Настенный котел какой выбрать: рейтинг 2019-2020 года самых надежных для частных домов и отзывы владельцев

Что лучше — настенный или напольный газовый котел: какой все таки выбрать, какой наиболее эргономичный и принципы их действия

Из всех источников тепловой энергии наиболее эффективными и экономичными считаются газовые котлы.

Они используются как в частных отопительных системах, так и в мощных тепловых станциях промышленного уровня.

Возможности и надежность газовых агрегатов способствовали разработке большого количества конструкций, обладающих различными особенностями, набором функций и прочими качествами.

Особенным разнообразием отличаются агрегаты средней и малой мощности, которые используются для отопления частных домов.

Рассмотрим две наиболее распространенные группы — настенные и напольные.

Настенные газовые котлы

Настенные газовые котлы разрабатывались для использования в небольших жилых помещениях, где нет возможности отвести для котельной отдельное помещение.

Они монтируются навесным способом на прочные (несущие) стены, поэтому вес и габариты агрегатов ограничены. Как правило, мощность настенных котлов не превышает 40 кВт, а размеры примерно соответствуют формату навесных шкафов кухонных гарнитуров.

Помимо размеров и веса настенные котлы не имеют принципиальных отличий от напольных моделей и работают на общих правилах.

Разновидности

Существуют разные конструкции настенных котлов. Их можно разделить по собственным признакам.

По набору функций:

• одноконтурные. Предназначены только для нагрева теплоносителя и подачи его в отопительную систему;
• двухконтурные. Способны одновременно нагревать теплоноситель и готовить горячую воду для бытовых потребностей.

По типу камеры сгорания:

• атмосферные. Традиционная конструкция газового котла, в котором процесс горения происходит в открытой горелке с забором воздуха прямо из помещения. Удаление дыми происходит обычным способом, под действием тяги печного типа;
• турбированные. Камера сгорания изолирована от атмосферы помещения, что способствует чистоте и отсутствию нежелательных компонентов. Подачу воздуха для горения обеспечивает вентилятор турбонваддува. Возникает избыточное давление, которое способствует выводу дыма из котла. Обычно для таких конструкций используется собственный горизонтальный дымоход коаксиального типа.

По типу теплообменника:

• раздельный. Котлы оснащены либо одним (первичным) узлом, Либо двумя — первичный нагревает теплоноситель, а вторичный (пластинчатый) в проточном режиме косвенным способом готовит ГВС;
• совмещенный (битермический). Конструкция этого узла близка к коаксиальным типам. По одной полости протекает теплоноситель, по другой — вода для бытовых нужд. Конструкция эффективна, позволяет избежать скачков температуры, но очень быстро покрывается слоем известковых отложений, практически не поддающихся очистке.

По материалу теплообменника:

• стальной. Используется на недорогих моделях;
• медный. Применяется на продукции топовых производителей. Обеспечивает высокую теплопередачу и долговечность.

ОБРАТИТЕ ВНИМАНИЕ!

Настенные агрегаты обладают всеми возможностями и производятся во всех существующих конструкционных видах. Единственным видом, который не производится в настенном варианте, является энергонезависимый котел.

Плюсы и минусы

К достоинствам настенных газовых котлов следует отнести:

• компактность, малый вес, способность гармонично вписаться в интерьер помещения;
• широкий выбор функционала и мощности агрегатов;
• надежность, стабильность работы;
• простота управления;
• небольшой расход газа;
• удобство обслуживания и ремонта.

Недостатками можно считать:

• монтаж агрегатов трудоемкий, нуждается в использовании специального оборудования;
• мощность котлов ограничена из-за необходимости снизить нагрузку на несущие поверхности.

Имеющиеся минусы настенных котлов не являются серьезным препятствием для пользователей. Большинство владельцев сравнительно небольших помещений предпочитает покупать настенные модели.

Напольные газовые котлы

Напольные газовые котлы устанавливаются прямо на пол или, если он деревянный, на негорючую подставку. Это снимает ограничения на вес и габариты агрегата, но вводит требования к помещению — для напольных котлов нужна обособленная комната с полноценным дверным и оконным проемом.

При этом, возможности напольных котлов заметно выше, особенно это относится к параметрам ГВС. Все одноконтурные напольные котлы могут быть подключены к внешнему накопительному бойлеру косвенного нагрева, что позволяет получить полноценное снабжение горячей водой, заметно опережающее параметры двухконтурных моделей.

Основной принцип работы агрегатов ничем не отличается от настенных моделей, вся разница заключается только в мощности, размерах и условиях установки.

Виды

Напольные газовые котлы изготавливаются во всех известных конструкционных вариантах. Их можно разделить на группы по разным признакам.

По функционалу:

• одноконтурные. Используются только для нагрева теплоносителя. При подключении внешнего бойлера способны обеспечивать помещение горячей водой на уровне централизованного водоснабжения;
• двухконтурные. Способны параллельно с нагревом теплоносителя готовить горячую воду для хозяйственных нужд.

По способу теплопередачи:

• конвекционные. Обычный нагрев жидкости в пламени газовой горелки;
• конденсационные. Производится двухступенчатый нагрев теплоносителя — сначала в конденсационной камере от тепла выводимого дыма, а затем обычным способом. Конструкция имеет специфические условия для полноценной работы — нужен либо низкотемпературный контур (теплый пол), либо перепад наружной и внутренней температур не должен превышать 20°;
• парапетные. Агрегаты, способные работать в небольших помещениях без отопительного контура. В корпусе есть отверстия, которые обеспечивают циркуляцию горячего воздуха по принципу конвектора.

По материалу теплообменника:

• стальной. Используется нержавейка толщиной до 3 мм;
• медный. Как правило, устанавливают змеевик, обладающий высокой долговечностью и теплопередачей;
• чугунный. Применяют на мощных моделях, нуждающихся в стабильной и эффективной работе узла.

По типу электропитания:

• энергозависимые. Котлы, в конструкции которых использованы устройства, требующие подключения к сети;
• энергонезависимые. Агрегаты, способные работать без подключения к сети электропитания.

ВАЖНО!

Энергонезависимые котлы хороши в условиях нестабильной подачи энергии, или в отдаленных поселках.

Достоинства и недостатки

К достоинствам напольных котлов принято относить:

• высокая мощность, способность отапливать помещения большой площади;
• надежность, устойчивость к эксплуатационным нагрузкам;
• возможность соединять некоторые модели в каскад большой мощности;
• широкий выбор моделей с разными конструкционными особенностями и мощностью;
• простота установки;
• управление напольными котлами понятно и доступно любому пользователю.

Недостатками считаются:

• для установки напольных котлов необходимо специальное помещение с закрывающимися дверями и оконным проемом;
• для использования в квартирах или маленьких домах они не подходят;
• высокая мощность автоматически означает большой расход топлива.

ОБРАТИТЕ ВНИМАНИЕ!

Несмотря на имеющиеся недостатки, спрос на напольные котлы стабильно высок. Пользователи предпочитают надежность и долговечность, которыми обладают напольные котлы.

Принцип действия

Принцип действия обоих видов котлов одинаков. Основные элементы конструкции — газовая горелка и теплообменник, объединенные в единый узел.

Теплоноситель поступает в теплообменник, получает там высокую температуру и выводится во вторичный узел. В нем тепловая энергия частично расходуется на подготовку горячей воды. После этого жидкость проходит в трехходовой кран, смешивается в заданной пропорции с более холодным обратным потоком и получает температуру, обусловленную текущим режимом работы.

После этого теплоноситель выходит из котла и поступает в отопительный контур, где делает круг и в качестве обратного потока вновь поступает в котел. Подача воздуха производится турбовентилятором, который также обеспечивает вывод дыма.

Циркуляция происходит под действием циркуляционного насоса. Работа постоянно контролируется платой управления и системой датчиков, способных обнаружить все неполадки и сразу оповестить о них владельца.

Что лучше – настенный или напольный?

Преимущество того или иного вида можно указать только применительно к конкретному помещению.

Если имеется квартира или маленький дачный домике, не располагающие лишней площадью, следует использовать настенный котел. Напольные конструкции хороши в больших домах, где есть возможность установить котел в отдельное помещение.

Как правило, котельную проектируют еще на стадии изготовления рабочих чертежей дома. В плане конструкционных или эксплуатационных преимуществ у обоих видов никакого первенства нет.

Все сравнения могут производиться только в отношении определенного места установки или использования.

Что выбрать

Для наглядности составим таблицу особенностей обоих видов:

Характеристики и особенности	Настенные	Напольные
Функциональные возможности	Полный комплект
Долговечность	Зависит от режима эксплуатации. В среднем, от 10 до 20 лет
Мощность	До 50 кВт	До 500 кВт
Электропитание	Энергозависимые конструкции	Энергозависимые и энергонезависимые конструкции
Стоимость	Средняя	Средняя и высокая
Вес, размеры	Небольшие, средние	Средние, большие
Сложность управления и обслуживания	Средняя

Итоги – что все таки лучше?

Напольные модели обладают расширенными возможностями относительно подачи ГВС. Если использовать внешний бойлер, то производительность такого комплекта значительно превысит возможности двухконтурных моделей как настенных, так и напольных.

В то же время, настенные котлы компактны, не требуют лишнего места, потребляют небольшой объем топлива. Поэтому сравнивать их с точки зрения «лучше-хуже» некорректно.

Для каждого котла есть свои оптимальные условия, в которых он заметно превосходит все альтернативные варианты.

Полезное видео

Данное видео поможет вам разобраться, какой котел все же выбрать, настенный или напольный:

Заключение

Настенные и напольные газовые котлы выполняют одни и те же функции, отличаясь лишь способом монтажа и размерами. Они обеспечивают помещения теплом и ГВС, создают комфортный и уютный микроклимат.

Вся разница заключается в компактности и небольшом весе настенных моделей и мощности, увеличенных возможностях напольных котлов. Принципиальных конструкционных расхождений между ними нет, выбор обычно производится исходя из размера и конфигурации обслуживаемого помещения.

Большинство пользователей руководствуется своими потребностями и финансовыми возможностями, стараясь получить оптимальный вариант источника тепловой энергии по доступной цене.

With oil and LPG boilers, you need to keep fuel on your property in a safe storage container and have your fuel delivered on a regular basis. 90005 90002 Of the gas combi boilers we have included in this article, the following are compatible with LPG: 90005 90061 Worcester Bosch Greenstar i 90062 90061 Viessmann B2KB Vitodens 200W 90062 90061 Vaillant ecoTEC plus Combi 90062 90061 Ideal Vogue Max Combi 90062 90002 If you are looking for an oil fired combi boiler, here are 3 of the best oil combi boilers on the market as well as average costs.90005 90210 90211 90212 90213 Combi Boiler Model 90214 90213 Available Outputs (kW) 90214 90213 Approximate cost of boiler (excluding installation) 90214 90217 90212 90219 Worcester Bosch Greenstar Heatslave II 90220 90219 18, 25, 32 90220 90219 £ 2,000 — £ 2,400 90220 90217 90212 90219 Grant Vortex Blue Internal 90220 90219 15-21, 21-26, 26-36 90220 90219 £ 1,500 — £ 2,500 90220 90217 90212 90219 Warmflow Kabin-Pak Combi 90220 90219 21, 26, 33 90220 90219 £ 1,900 — £ 2,200 90220 90217 90248 90249 90028 Which is the Best Combi Boiler Size for Your Home? 90029 90002 Combi boilers are available in a range of outputs to suit homes of most sizes from 1 bedroom flats to 4 bedroom houses and it’s vital that you get a combi boiler with the right output installed for your home.A combi that’s too small will not be able to meet your heating and hot water requirements, while a combi that’s too powerful will end up increasing your energy bills. 90005 90002 However, if you have plans to expand your home, e.g. you’re adding a conservatory, converting a loft space and / or adding more inhabitants, you may want to get a bigger boiler to ensure it meets your long term needs. 90005 90002 Generally speaking, the more bedrooms and bathrooms you have, the higher the output of your boiler needs to be.A professional installer will be able to recommend the best combi boiler for your home but to help you narrow down your search, we’ve put together some guidelines based on industry recommendations: 90005 90210 90211 90212 90213 Bedrooms 90214 90213 Bathrooms 90214 90213 Radiators 90214 90213 Recommended Output 90214 90217 90212 90219 1 — 2 90220 90219 1 90220 90219 Up to 10 90220 90219 24 — 27kW 90220 90217 90212 90219 2 — 3 90220 90219 2-3 ​​90220 90219 Up to 15 90220 90219 28 — 34kW 90220 90217 90212 90219 4+ 90220 90219 3+ 90220 90219 Up to 20 90220 90219 35 — 42kW 90220 90217 90248 90249 90002 For larger properties with multiple bathrooms, lots of inhabitants or a particularly high need for hot water, a combi boiler may not be suitable.This is because a combi boiler takes its water supply directly from the mains and heats on demand when a tap or shower is turned on. If multiple outlets require hot water at the same time, the combi boiler may struggle to maintain a consistent supply. For this reason a professional heating engineer may recommend a system or regular boiler rather than a combi as these systems include a hot water cylinder that stores a higher volume of hot water. 90005 90028 Best Combi Boilers for 1-2 Bedroom Home 90029 90002 Combi boilers are ideal for small homes with 1-2 bedrooms and one bathroom.Typically, the best size combi boiler for these homes is between 20-27 kW. If you have two bathrooms, e.g. a family bathroom and an ensuite, you may need a slightly more powerful combi boiler. Here are the best combi boilers in that size range: 90005 90061 Vaillant ecoTEC plus 25 kW 90062 90061 Worcester Bosch Greenstar i 25 kW 90062 90061 Baxi 800 Platinum Combi 24 kW 90062 90061 Viessmann B2KB Vitodens 200W 26 kW 90062 90061 Ideal Vogue Max Combi 18 or 26 kW 90062 90028 Best Combi Boilers for 3-4 Bedroom Home 90029 90002 Homes with 3-4 bedrooms and two bathrooms may need a more powerful combi boiler to cope with the higher number or radiators and greater demand for hot water.Here are the best combi boilers in that size range: 90005 90061 Vaillant ecoTEC plus 32 or 35 kW 90062 90061 Worcester Bosch Greenstar i 32 kW 90062 90061 Baxi 800 Platinum Combi 28 or 33 kW 90062 90061 Viessmann B2KB Vitodens 200W 30 or 35 kW 90062 90061 Ideal Vogue Max Combi 32 kW 90062 90028 Best Combi Boilers for 5+ Bedroom Home 90029 90002 Generally speaking, a combi boiler is not suitable for a bedroom with lots of bedrooms and multiple bathrooms. It’s likely that an engineer will recommend a system boiler which incorporates a hot water cylinder to store a higher volume of hot water.If you have an older home or weak water pressure in your area, a regular boiler may be more suitable. 90005 90002 Having said that, there are some manufacturers which produce powerful combi boilers for larger homes: 90005 90061 Vaillant ecoTEC plus 38 kW 90062 90061 Baxi 800 Platinum Combi 40 kW 90062 90002 To help in your search for the best combi boiler for your home, you can compare combi boilers with different outputs in these guides: 90005 90028 Benefits of a Combi Boiler 90029 90002 No matter which of the best combi boilers you choose, there are a number of general benefits to having a modern combi boiler provide your central heating and hot water.90005 90002 Combi boilers are the most commonly installed boiler type in the UK. When you turn on the heating or a tap, the combi boiler responds within seconds taking water directly from the mains supply and heating it on demand. There’s no need for a tank of cold water in the attic or a large storage cylinder in an airing cupboard — the combi boiler does it all from one compact unit. 90005 90002 90007 High levels of efficiency 90008 90004 All combi boilers installed in UK homes have to meet efficiency levels of at least 92%, meaning that combi boilers achieve incredibly high levels of efficiency which will not only help to lower your carbon footprint but could reduce your energy bills too.90005 90002 90007 Can help to lower your energy bills 90008 90004 Thanks to their high energy efficiency, a combi will help to save you money on your energy bills. A combi boiler with 92% efficiency, will only lose 8% of the fuel it uses, meaning that for every £ 1 you’re spending on your energy bills, only 8p is wasted. 90005 90002 So, if you’re planning to replace your current boiler with a modern combi boiler, then you could potentially be saving £ 315 * a year on your energy bills. 90005 90002 90007 Space saving thanks to their compact size 90008 90004 There are 3 different types of boiler: combi, regular (traditional or heat-only too) and system.90005 90002 Out of these, combi boilers are the only type that do not need any water tanks or storage cylinders. This is because everything it needs to heat your home and hot water is wrapped up into a single compact unit. 90005 90002 90007 Hot water to taps on demand 90008 90004 Rather than the hot water being stored in a hot water cylinder, which can mean having to wait for hot water, like with regular and system boilers, combi boilers take water straight from the mains and heat it on demand when you turn the hot water tap.Not only does this get you quicker access to hot water but stronger water pressure too. 90005 90002 90007 Easy to install 90008 90004 With everything being wrapped up into a single unit, combi boilers are the easiest type of boiler to install, especially when replacing an old combi boiler with a new one. This will help to save you time and money when it comes to the installation. 90005 90028 How does a combi boiler work? 90029 90002 Combi boilers are the most commonly installed type of boiler in the UK for a number of reasons.While system and regular boilers require a hot water storage cylinder, a combi boiler is an all-in-one unit which will produce hot water for central heating and your taps. This saves a great deal of space in your home and often means it can be tucked away in a kitchen cupboard. With no water tank or cylinder needed it also results in a simpler and faster installation. 90005 90002 A combi boiler takes its water supply directly from the mains which usually results in a stronger pressure. A combi boiler gives you the luxury of hot water on demand so there’s no need to worry about running out and having to wait for the tank to refill.CCombi boilers work by heating water directly from the mains, so you do not need a hot water storage cylinder or cold water tank. 90005 90028 Finding the Best Combi Boiler Installer 90029 90002 While the price of installation will vary depending on the type of installation, you can really help yourself by comparing quotes from multiple combi boiler installers and that’s where we can help. 90005 90002 Complete our simple online form to let us know the type of work you need, which should not take long at all, and we’ll match your needs with fully-qualified Gas Safe engineers in your local area.You’ll soon be contacted by up to 3 heating engineers who will all provide a free quote, leaving you free to compare them.

Each of the types of central heating boilers available have their own pros and cons, some vastly different, while others only seem to only change aesthetically.90004 90009 Condensing Central Heating Boilers 90010 90002 It is now law that all central heating boilers installed across the UK have to be condensing. Condensing boilers have a larger heat exchanger and generate heat from excess fuel which would otherwise be wasted, making them much more efficient than non-condensing boilers. 90004 90002 One of the issues often mentioned with condensing boilers is the pluming effect it creates from the flue terminal, which is often mistaken for steam. The pluming is due to droplets of water that are held in suspension throughout the boilers flue, and is not a danger, although is considered a nuisance and will occur for all the time that the boiler is running.Because of this, the placement of a condensing boiler can be more difficult. 90004 90002 With a minimum of efficency of 92%, no matter whether you install a Combi, Regular or System boiler, a condensing boiler will help to reduce your impact on the environment and could also see your energy bills drop. To give this efficiency rating some context, for every £ 1 you spend on heating your home, only 8p is wasted. When you compare this to non-condensing boilers that can have an efficiency rating around the 70% mark, this is quite a saving on your energy bills.90004 90009 What Boiler Type Should I Get? 90010 90002 Rather than thinking considering the number of bedrooms in your home to find the most suitable central heating boiler, you should add up the total number of the following: 90004 90021 90022 Radiators 90023 90022 Bathrooms 90023 90022 People in the home 90023 90028 90002 To help you get the right size boiler for your home, use our boiler size guide or boiler size calculator tool. 90004 90002 The boiler type you should get is dependent on your size, cost, output, storage and efficiency requirements.Whatever your needs, it’s imperative that you get professional advice and at least 3 quotes from Gas Safe engineers before you proceed. 90004 90009 Combi Boilers 90010 90002 The most popular boiler type on the market today, Combi boilers (short for Combination) account for more than half of boilers sold within the UK. 90004 90002 This is mainly due to its convenience, as most central heating systems will heat a copper cylinder located in an airing cupboard using a boiler to provide hot water, but a Combi boiler will heat the water needed around the house for taps and such from within its unit, and is combined with a central heating system.90004 90002 A combi system will not require a cold water tank or separate water cylinder to supply it, which means that the costs of hot water will be a little lower than with a boiler that holds water in a cylinder. 90004 90002 Benefits of a Combi boiler: 90004 90021 90022 Compact size — able to fit in a cupboard 90023 90022 Simple installation 90023 90022 Hot water on demand 90023 90022 No need for any tanks or cylinders 90023 90022 Highly efficient 90023 90022 Mains water pressure 90023 90028 90002 One of the few downsides to a Combi boiler is that hot water can only be sent to one tap at a time, whereas System and Regular boilers store the hot water in a cylinder ready to be sent to as many taps as required, until the cylinder needs filling up again.90004 90002 90060 Finding the right Combi boiler for your home 90061 90062 In general, Combi boilers are not recommended for larger homes with any more than 2 bathrooms as they can not supply hot water to multiple taps or showers at once, unlike Regular and System boilers. 90004 90064 90065 90066 90067 Number of Bedrooms 90068 90067 Number of Bathrooms 90068 90067 Number of Radiators 90068 90067 Recommended Output 90068 90075 90066 90077 1-2 90078 90077 1 90078 90077 Up to 10 90078 90077 24 — 27kW 90078 90075 90066 90077 2-3 90078 90077 2-3 90078 90077 Up to 15 90078 90077 28 — 34kW 90078 90075 90096 90097 90009 System Boilers 90010 90002 The way a System boiler operates is somewhere between Combi and Regular boilers, as the majority of components are built into the unit but but a cylinder or tank is still required to store hot water.Like Combi boilers, System boilers take their water supply directly from the mains whereas a Regular boiler has a cold water tank in the loft. They heat the water directly from the mains, which is then stored in a hot water cylinder, ready for use when a hot water tap is turned or the central heating is switched on. 90004 90002 Some of the benefits of a System boiler include: 90004 90021 90022 Quicker installation than a Regular boiler — no need for a cold water feed tank to be installed in the loft 90023 90022 Can meet a high demand for hot water 90023 90022 Stronger water pressure than a Regular boiler 90023 90022 Quick response when required 90023 90028 90002 In terms of things you should consider before installing a System boiler, it’s worth nothing that the hot water is not instant, like with a Combi boiler, and the amount of hot water available to your home will be determined by the size of the hot water tank.In addition to this, the hot water tank will be well insulated to reduce heat loss — less heat loss means that less energy is wasted. 90004 90002 90060 Finding the right System boiler for your home 90061 90062 Depending on the size of your home, the number of bathrooms and the number of radiators, the System boiler will need to be a certain output — which determines how powerful it is not. You should not simply look to have the most powerful System boiler installed as this will drive your energy bills up, while a boiler with an output that’s too low will not be able to meet the heating and hot water demands of your home.90004 90064 90065 90066 90067 Number of Bedrooms 90068 90067 Number of Bathrooms 90068 90067 Number of Radiators 90068 90067 Recommended Output 90068 90075 90066 90077 1-2 90078 90077 1 90078 90077 10 90078 90077 27kW 90078 90075 90066 90077 3 90078 90077 2-3 90078 90077 Up to 15 90078 90077 32kW 90078 90075 90066 90077 4 90078 90077 3+ 90078 90077 Up to 20 90078 90077 36 — 40kW 90078 90075 90096 90097 90009 Regular Boilers 90010 90002 Regular boilers are the oldest type of central heating boiler around but do not let that put you off installing one, if you live in a suitable home, because they’ve really advanced over the years to be more efficient than ever.90004 90002 While the latest addition to the types of central heating boilers, the Combi boiler, has everything wrapped up into one unit, Regular boilers require several parts, including: 90004 90021 90022 Boiler 90023 90022 Heating controls 90023 90022 Hot water cylinder 90023 90022 Cold water storage tank in the loft 90023 90022 Feed and expansion cistern 90023 90028 90002 The cold water storage tank fills with water from the mains, which then travels down to the hot water cylinder, where it is heated up and stored, ready to circulate to taps, showers — several at the same time if necessary.90004 90002 When it comes to the central heating, cold water from the same tank in the loft goes to the boiler, where a heat exchanger warms up the water which is then pumped to the hot water storage tank, circulating around the radiators when the thermostat is turned up. 90004 90002 Benefits of installing a Regular boiler include: 90004 90021 90022 Meet high demand for heating and hot water 90023 90022 Increased in efficiency over time 90023 90022 An immersion heater can be fitted to the hot water tank as an alternative way to heat water 90023 90022 Fully compatible with solar thermal panels 90023 90028 90002 On the other hand, Regular boilers can take up a lot of space so are not suitable for properties lacking in space, the hot water is not instant as it’s stored in a cylinder, if the cylinder is not insulated the water could be susceptible to heat loss and the installation could be a long and expensive process.90004 90002 Regular boilers are best suited to large homes, with a high demand for heating and hot water, that already has the pipework for a Regular central heating boiler. If you live in a property with 2 or fewer bathrooms, you’d be better off considering a Combi or System boiler. 90004 90064 90065 90066 90067 Number of Bedrooms 90068 90067 Number of Bathrooms 90068 90067 Number of Radiators 90068 90067 Recommended Output 90068 90075 90066 90077 1-2 90078 90077 1 90078 90077 10 90078 90077 27kW 90078 90075 90066 90077 3 90078 90077 2-3 90078 90077 Up to 15 90078 90077 32kW 90078 90075 90066 90077 4 90078 90077 3+ 90078 90077 Up to 20 90078 90077 36 — 40kW 90078 90075 90096 90097 90247 90002 90249 Get Free Boiler Quotes 90250 90004 90062 Get quotes to supply and fit a new boiler now 90002 90004 90247 90009 Where to Install a Central Heating Boiler 90010 90002 Boilers can be installed pretty much anywhere around a property, it’s even safe to have one installed in a bedroom.The most common places to have the boiler unit installed, however, is a kitchen or utility room. 90004 90002 Due to the compact nature of many modern boilers, they can be installed inside a cupboard, to be kept out of sight and mind. When looking for a new boiler, you’ll find that some are to be installed on wall, while others have to stand on the floor. 90004 90002 90060 Wall Mounted Boilers 90061 90004 90002 Most boilers produced today are made to be wall mounted, with more compact and lighter heat exchangers created with materials including lightweight cast iron, stainless steel, copper or aluminium.90004 90002 Wall mounted boilers come in many versions, such as with a Fanned Flue or Room Sealed. As with most new boilers, the wall mounted type of boiler is required to have fitted a «system by-pass», which is required to filter water throughout the boiler appliance to prevent the often loud noise that boilers are known to create, called » kettling «. 90004 90002 90060 Free Standing Boilers 90061 90004 90002 Usually created to be narrow enough to fit snugly between fitted kitchen units as other appliances would, these floor standing boilers can be installed in other suitable locations also.Free standing boilers were a popular choice in the 70’s and 80’s but are still a great option for homeowners who may not have the wall space for a wall mounted boiler now. 90004 90002 90060 Back Boilers 90061 90004 90002 Old back boilers located in fireplace areas in homes must be replaced due to new building regulations, and these are usually replaced by a high efficiency or a condensing boiler. 90004 90002 Back boilers should not be sold in many cases because of the open flued model, unless it is much too complex or pricey to install a new boiler replacement.90004 90002 Often people will choose to fill the space a back boiler leaves with a gas fire and install a new condensing Combi boiler elsewhere in the property. 90004 90009 Central Heating Boiler Add-ons 90010 90002 In addition to the boiler itself, it’s recommended that an installer performs a powerflush on your heating system and that a Magnetic Filter is fitted when replacing the boiler. 90004 90002 90060 Powerflush 90061 90062 A Powerflush clears the sludge and debris that can build up in the heating system over time, which if left can cause the system to lose efficiency and possibly even break down.The Powerflush itself involves a pump being attached to the central heating system, sending chemicals through the pipes, boiler and radiators to clear any build-up. 90004 90002 90060 Magnetic Filter 90061 90062 While a Powerflush clears the heating system of debris once it’s built up, a Magnetic Filter prevents it from building up in the first place. With a Magnetic Filter attached to the system, any debris in the system will be collected, helping to prevent blockages and increase the life of the boiler.90004 90009 New Central Heating Boiler Costs 90010 90002 All central heating boilers have their own price tag and tends to be in the region of £ 600 £ 2,500. You will then need to consider the cost of installation, which will add to the price of the boiler itself. There are several factors that will determine the total cost of installing a new boiler: 90004 90021 90022 Type of boiler (Combi, Regular or System) 90023 90022 Boiler manufacturer and model 90023 90022 Whether it’s a like-for-like boiler replacement (Combi for a Combi, for example) 90023 90022 If the boiler is being installed in a new location 90023 90028 90002 In addition to the above, the cost of installation will ultimately be determined by the heating engineer carrying out the boiler installation.To find the best possible deal on a new central heating boiler installation, we highly recommend comparing quotes from multiple installers. 90004 90009 Get Free Central Heating Boiler Quotes 90010 90002 Whether you’ve found the right central heating boiler for your home or are not sure, you can get free installation quotes from boiler installers near you with Boiler Guide. 90004 90002 Complete our simple online form, letting us know the type of work you need and we’ll match your requirements with local heating engineers.90004 90002 If you’re not sure which type of boiler is suitable for your home, then a professional heating engineer will be able to carry out a survey of your home and advise. 90004 90247 90002 90249 Get Free Boiler Quotes 90250 90004 90062 Get quotes to supply and fit a new boiler now 90002 90004 90247 .90000 CHOOSE GAS BOILER | With Your Hands 90001 90002 Despite the fact that gas prices are climbing up, the boilers in which it is used as fuel are still very indispensable. Now that most of the dachas are gasified (if you are unlucky and you do not enter into a happy number of such, then see the article How and what to choose solid fuel boiler), many summer residents want to install a gas boiler for heating , in turn, and at home. Before you ask yourself the question where to buy a gas boiler, with the help of the below, try to determine first with the choice of what you need.90003 90004 1 CHOICE — CONVECTION OR CONDENSATION BOILER? 90005 90002 A convection gas boiler is a standard type of device that uses only the combustion energy of the fuel. The layout of these boilers is very simple, and they are relatively cheap. The condensing boiler, because of its design, produces more heat at the outlet than in principle it can stand out when burning gas fuel. The so-called conditional efficiency (also called the fuel utilization factor) in such boilers can reach 110 percent.Condensing boilers use the heat of water vapor in the flue gases that form during combustion, and give additional energy to the heat carrier when passing from the gaseous state to the liquid. This boiler has a more complex device and costs a little more than convectional, but its operating costs are lower because its consumption decreases by a quarter and sometimes by a third 90003 90004 2 SELECT — OPEN OR CLOSED CAMERA? 90005 90002 Boilers with an open combustion chamber (with natural draft) take air from the room in which they are located.In them, traction does not depend on the power grid and they are cheap. When choosing such a boiler, take care of the good ventilation of the room in which it will be installed, and provide in the project of the house a suitable chimney 90003 90002 In boilers with a closed combustion chamber, the supply of combustion air and the removal of combustion products are forced — with the help of a fan, through a coaxial chimney (pipe in a pipe). This device allows you to supply air both from the premises and from the street.One tube collects air, and the other — the output of combustion products, which makes it possible to more compactly mount the system. Also, such a boiler can be used in rooms that are not equipped with a fixed chimney. The drawback of this boiler is its energy consumption — electricity is needed for the fan. 90003 90004 3 CHOICE — WHICH MATERIAL OF THE HEAT EXCHANGER? 90005 90002 The heat exchanger is one of the important components of the gas boiler. It is a metal container in which the coolant is heated.In boilers, it can be distinguished by the materials of which it is made. In cheap models of hinged gas boilers, steel heat exchangers are often used, the main advantage of which is excellent ductility. It is of fundamental importance, since a constant direct flame of the burner can cause thermal stresses, which can cause cracks in the heat exchanger. With steel models this will not happen. In addition, they are much lighter than similar cast-iron ones. The minus of steel heat exchangers lies in their susceptibility to corrosion and, therefore, in in a shorter service life.»Cast-iron» are more massive, heavy and are much more expensive. They are sensitive to a large temperature jump (thermal shock), but almost do not rust — their service life can be more than 50 years. Heat exchangers made of copper, which are used for compact wall-mounted boilers, are light and practically stainless. Most units can be removed from the boiler and cleaned as they are used. But such heat exchangers are considered the most expensive. They require special attention to exploitation, because with the leakage of water burn faster.90003 90004 4 CHOICE — WALL OR FLOOR BOILER? 90005 90002 Installation of the boiler in the house is related to its qualities and characteristics, such as weight (it depends most on the heat exchanger material) and power. 90003 90002 The power of both starts from 18 kilowatts. 90003 90002 Floor boilers can have a power of up to hundreds of kW and more, and wall-mounted, usually — 32 kW. 90003 90002 The wall-mounted boiler is usually lighter, smaller and costs less than the floor, but is not equipped with a cast-iron heat exchanger or remote burner.90003 90002 Therefore, boilers that use 2 type of fuel (diesel fuel and natural gas) are produced only in the floor solution. Most often, floor models are designed for heating homes with an area of ​​400 meters. So if you are the owner of a large cottage (from 100 to 300 m2), then you are better suited wall-mounted boiler. 90003 90004 5 CHOICE — ONE-CONNECTION OR TWO-CONVENTION BOILER? 90005 90002 A single-circuit boiler is simpler and cheaper. But it is only suitable for heating, and you will not receive hot water when using it.The dual-circuit boiler has an 2 heat exchanger, which is used for both heating and water heating. Therefore, it is possible to solve 2 problems at once. Most of these boilers are made according to the principle of the primacy of the supply of hot water. This means that when the flow of hot water is switched on, the coolant does not heat up. Therefore, in order to level the fluctuations in the temperature of the coolant, it is recommended to install a heat accumulator. 90003 90002 If you already have an electric boiler for heating water, you do not need to install a double-circuit boiler, enough for a single-circuit boiler.With the help of gas, heating the water will certainly be cheaper, but installing a dual-circuit boiler will require a reworking of the existing pipeline system. 90003 90002 90003 90004 6 CHOICE — A SINGLE-STAGE OR A TWO-STEP BOILER? 90005 90002 Gas boilers can be as single-stage, with one power level, and two-stage, with 2 levels, and also with modulation (stepless regulation) of capacity. When choosing a boiler for this characteristic, keep in mind that its full power you will need only in the coldest, the rest of the time you can do with a boiler and less power.On the other hand, choosing a boiler with a lower capacity, it will be possible to detect that the temperature in the house in the cold is not comfortable enough. Therefore, it is more correct to consider the option of purchasing a two-stage boiler. It has the following advantages: 90003 90002 Increase of the service life due to the reduction of the cycles of switching on and off; 90003 90002 Work at the first stage with reduced capacity and a moderate number of switching on and off will save gas, and hence finance; 90003 90002 A smaller volume of flue gases and toxic substances released into the environment.90003 90004 7 CHOICE — BOILER FORCED OR NATURAL CIRCULATION? 90005 90002 In units with natural circulation, the heated coolant under the influence of the density drop gravity goes to the radiators. Units with forced circulation (coolant supplied by an electric pump) consume 10-15% less gas and better maintain the thermal regime. Some types of boilers, for example, condensing and hinged, have only a forced circulation type. For heating cottages with an area of ​​more than 100 m2, you should choose this type of boiler.90003 90002 Installation of a boiler with natural circulation will cost more and will require the use of pipes with a large cross-section, which may not approach the interior of your home. 90003 90002 90055 Nuances when choosing: 90056 90003 90058 90059 A closed-chamber boiler uses air from the street, which is forced through a special pipe by a fan. 90060 90059 A boiler with an open combustion chamber takes air from the room. 90060 90059 Floor boilers, as a rule, are more powerful and installed in large houses.90060 90059 The floor gas boilers are large enough, so it is better to install them in the basement. 90060 90059 The most practical material for the heat exchanger is high-quality steel. 90060 90069 90070 90004 A modern gas boiler — what is it? 90005 90002 90003 90002 Connecting the house to the gas main eliminates the owners from solving problems with heating and hot water supply of the home. In addition, modern gas boilers can significantly save on the consumption of blue fuel. 90003 90002 Power — the main criterion when choosing a gas boiler (as, indeed, a boiler unit of another type).But this does not end with questions about the future heat generator in the house. Gas boilers are wall and floor, convection and condensing, one- and two-circuit (that is, working on heating and hot water supply). Which unit to purchase depends on the specific situation and personal preferences of the owners, as well as on their financial capabilities. Whatever it was, when selecting a boiler, one should be guided not by immediate benefits, but by significant dividends in the future, that is, to focus on efficiency, economy and ease of maintenance of boiler equipment.90003 90002 Owners of country houses planning to install a boiler in the kitchen should know that according to Russian standards the unit’s capacity should not exceed 35 kW. If by calculation the cottage needs more powerful heating equipment, then the boiler should be in a special room of at least 6 m2 with a ceiling height of at least 2,5 m, that is, the volume must be at least 15 m2. When installing a powerful condensing boiler, you should ensure the safe disposal of acid-containing condensate.90003 90002 Parts of the whole 90003 90002 Schematically, the arrangement of a gas boiler can be described in two sentences. Natural gas enters the combustion chamber, or rather the burner — the most important working element of the unit. When burning the blue fuel, hot gases are generated, which heat the heat exchanger filled with the heat carrier (water or antifreeze). Further, the heated liquid flows along the heating pipeline to the radiators or water heated floors. 90003 90002 The capacity and, to some extent, the cost of the boiler depend on the type of burner.In the basic kit of boiler equipment usually 90003 90002 includes simple, reliable, compact, quiet and inexpensive atmospheric burners. In most models, there is a transition to more efficient ventilator (supercharged) devices (air is forced into the combustion chamber by a fan). Such burners burn gas without residue, fuel is consumed rationally, which increases the efficiency of the boiler. But they are quite noisy and are more expensive than atmospheric analogues. 90003 90002 Adjusting the flame allows you to change the temperature of the heating medium without turning off the boiler.But this «trick» is taught only «advanced» modulating burners, the combustion of which is regulated smoothly, which has a positive effect on the service life of the unit (due to the reduction in on and off cycles) and provides almost 15- percent fuel economy. 90003 90002 Break away from the earth 90003 90002 For heating small cottages, modern wall-mounted boilers are ideally suited. Such units are essentially a mini-boiler house — in addition to the heat generator itself, the components of the hydraulic piping are arranged: circulation pump, expansion tank, make-up valves, automatic control devices, temperature sensors, safety equipment, etc.A special room is not required. The unit is most often placed in the kitchen — level with the cupboards for the dishes. But it happens that the boiler is mounted in a spacious bathroom or hallway. Models of the latest generation are distinguished by an elegant design. Such machines fit perfectly into a modern interior. The class of wall equipment includes both single-circuit and two-circuit units. The second option is great for winter cottages and houses with three to five points of water. Two-circuit boilers not only heat the building, but also serve as a kind of gas column (equipped with a built-in instantaneous water heater).True, with a large consumption of hot water, it is better to install a single-circuit unit plus a boiler (storage water heater) of indirect heating, operating from the heat exchanger of the boiler unit. 90003 90002 Demonstration of power 90003 90002 In houses larger than 300 m 90098 2 90099 install floor gas boilers. The floor units are famous for their reliability and very worthy efficiency. Sometimes such heat generators are reproached for massiveness and heaviness. However, such a judgment is only partly true.Modern floor boilers have compact dimensions and do not take up much space. 90003 90002 Relatively large mass of «napolniki» owe the cast-iron heat exchanger — an important technical «chip» of aggregates of this class. The fact is that the production of models of the latest generation uses a special eutectic cast iron. This metal is durable, homogeneous (has no internal caverns and other defects), is resistant to all types of corrosion. 90003 90002 Eutectic cast iron withstands large and sharp temperature changes, which is very important for the successful operation of the boiler (the pouring of ice water will certainly not cause the formation of cracks).The high heat capacity of the metal was used by 8 to achieve energy efficiency and save resources. From «advanced» cast iron heat exchangers of a special design are made — three-pass channels of passage of hot gases with an optimum configuration of heat transfer ribs. As a result, the heating medium temperature is reduced. Such heat generators are also called low-temperature generators. That is, in the boiler water is heated to 60-70 DC {in the traditional unit to 95 ° C), and when it comes from the return line it cools down to 40-50 ° С.At the same time, the workload on equipment is reduced, fuel consumption is reduced and the amount of harmful emissions to the atmosphere (nitrogen oxides, etc.) decreases. And, of course, the productivity of the unit improves. 90003 90105 Remove the cream 90106 90002 The exhaust gases carry with them not only numerous oxides, but also thermal energy. Save each calorie allow condensing boilers. In such units, heat is captured, which is released by condensation of the water vapor contained in the smoke (just like in the air conditioner, but with the opposite effect).At the same time, a cooled and cleaned off-gas comes out into the street, that is, it is solved 90003 90002 acute environmental problem of environmental safety of boiler equipment. True, when planning the installation of a condensing boiler, you need to consider a scheme for removing acid-containing condensate (water dissolves the oxide compounds). The volume of «caustic» water is good. Judge for yourself. When combustion 1 meg gas consumes 9 m3 air, resulting in the formation of 2 m3 water vapor, with the condensation of which forms 1,6 liters of liquid.The boiler with the power of 40-45 kW consumes 4-5 m3 / h. It is easy to calculate that an hour from the unit will result in more than 6 liters of condensate, which can not be easily discharged into the sewer system. Fortunately, many models aimed at the private consumer have a system of neutralization and drainage of condensation moisture. Technical details can be found with the representatives of the manufacturer (official dealers and others). The main thing is to specify in advance the key moments of the correct installation of equipment.90003 90105 A solid increase 90106 90002 The heat of condensation significantly increases the efficiency of heating technology. Here it is necessary to explain. The coefficient of efficiency of convection (traditional) boilers is determined by the so-called lower heat of combustion, that is, the amount of heat produced by complete combustion of the fuel and subsequent cooling of the combustion products to standard conditions. For EFFICIENCY, the ratio of useful thermal energy, providing heating and hot water supply and heat of combustion (lower heat) is adopted.For convection boilers this figure is 90-93%. The efficiency of condensation units is determined by the higher heat, that is, taking into account the condensation of water vapor (efficiency — 94-98%). But in promotional materials often appear out-of-bound values ​​in 104-107 and even 111%. And this is a very reasonable explanation. 90003 90002 In order to compare the two types of boiler equipment, the calculation of the efficiency is carried out according to one method — according to the lowest heat.To the obtained index, the percentages of the heat of condensation are added and pass over the 100% boundary. You can differently refer to similar marketing techniques. One thing is clear — condensing boilers are more efficient than convection units. The line of equipment of this class includes wall models up to 60 kW, which is of particular importance for owners of country houses, each having a square centimeter on the account. 90003 90002 Boilers are supplied with built-in thermostats, which control the water temperature set by the user, as well as the temperature limit, which can trigger the emergence of an emergency situation.90003 90002 The room thermostat switches off the boiler burner when reaching a comfortable temperature. But in this case the hot water-filled system continues to give off heat, and the room warms up to a temperature above the set one. 90003 90002 The increase in temperature at 2 ° C leads to a fuel overexpenditure of 6%. Synchronize the process allows smooth controllers, working with modulating burners. 90003 90002 If the boiler is equipped with a simple single-stage burner, it makes sense to install a programmer, that is, a room controller, which contains various programs that regulate the operation of the boiler (lowering the temperature at night and in the absence of owners, etc.). The greatest economic effect is achieved with the installation of integrated automation — a programmer plus a weather-compensated temperature controller (its sensor monitors the weather on the street). In this case, heating costs are reduced by almost 30%. In a house with floor heating, it makes sense to install a wireless collector management system that provides a comfortable mode in the house, and is set up for the daily schedule and personal preferences of the owners (the Uponor Smatrix Retrofit system).90003 90002 And do not count it for us? 90003 90002 The consumer can calculate the required boiler output independently. 90003 90002 If you have a compact house with well-insulated walls, then to determine the power of the heat generator, use the simple formula: 1 kW of heat energy for 10 m7 area of ​​the boiler is true for both single-circuit and dual-circuit units. 90003 90002 In the second case, the boiler automation is set to the DHW priority, that is, as soon as the hot water tap is turned on, the heating of the coolant in the heating circuit is suspended.However, owners of houses of a decent area and complex architecture — with panoramic glazing, high ceilings and second light, bay windows, warm loggias and ta — should act in accordance with the requirements of professionally executed design documentation (the heat supply section is included in the overall project of the house). 90003 90002 OUR ADVICE: 90003 90002 The power of the boiler should be determined on the basis of the calculation of the actual heat demand of the house. 90003 90002 If you are guided by rough estimates, it’s easy to make mistakes and you do not have to choose the one that you really need.90003 90002 A low-power boiler in the system will not be able to maintain a comfortable temperature. 90003 90002 Excess capacity also creates problems. At low load the boiler operates in the «stop-start» mode. 90003 90002 © Author: Tatiana Gagarina 90003 90070 90004 Gas boiler: operating rules 90005 90002 With the approach of winter, many people are thinking about how to heat a house, to properly start equipment that has been preserved for the summer, or what kind of heating device to purchase.On numerous questions on the operation of gas boilers we were answered by the specialists of TPK «Rusklimat» 90003 90002 © Author: MIKHAIL GUREEV 90003 90002 90055 Major mistakes when using a gas boiler 90056 90003 90002 The most part of possible problems is connected with poor-quality installation of the equipment and the first start-up. 90055 It is impossible, 90056 trying to save money, trust installation to specialists without sufficient knowledge, who do not know the regulatory requirements and who have not passed specialized training with equipment manufacturers.90055 The first start-up of the boiler is allowed only by a technician 90056 (engineer) of an authorized service center. He will check the correctness of the installation work of the entire system: 90003 90058 90059 connection of hydraulic systems of HVS and DHW, heating systems to the boiler; 90060 90059 the presence of mud filters and the necessary shut-off valves on the pipelines for connection. Makes calculations and checks: 90060 90059 pressure of the boiler in front of the boiler, in the heating system and compare the characteristics of the boiler; 90060 90059 conformity of quality of cold water and coolant to manufacturer’s requirements: 90060 90059 quality of boiler power supply and its compliance with the requirements of ROM; 90060 90059 correct installation of smoke removal systems and air ducts, their maximum permissible lengths and diameters; 90060 90059 system of flow-and-exhaust ventilation; 90060 90059 correct installation and tightness of the gas pipeline.90060 90069 90002 If there are no remarks, the engineer will proceed to the procedure itself and the scrapping work, which includes various checks and adjustments to the boiler control systems, adjusts its automation to the client’s needs, taking into account various factors: the heat source of the building, the type of heating system, the area of ​​the heated rooms, e. 90003 90002 The second most important problem is the neglect of annual maintenance, because of which, after a while, various failures begin to occur.This can be associated with the contamination of the combustion chamber, the fan of smoke exhaustion in boilers with a closed combustion chamber, the formation of carbon deposits on the ignition electrodes and other natural contaminants arising during operation. If you call a service engineer and timely eliminate such problems, the equipment will last for a long time. 90003 90002 90055 Work before the start 90056 90003 90002 What to do before the heating season, if the house already has a heating system, which besides the boiler includes heating appliances, supply pipes, stop valves, smoke removal system? 90003 90002 Diagnostics, setting up and first start-up of the boiler must be entrusted to qualified professionals, the rest can be checked and prepared for the upcoming colds yourself.90003 90002 Before starting, it is necessary to check the heating system for leaks-there are no leaks at the connection points, recheck the shut-off and control valves, remove and wash the mud filters at the cold water supply and return the heating system, check the operation of the voltage regulator and the boiler ground. Also it is necessary to check that in the smoke exhaust system the birds do not have a NEST. 90003 90002 When the boiler is started independently with the heating system closed, it is necessary to make sure that the pressure in the heating system is within the range allowed by the manufacturer.If the pressure has fallen during the downtime of the equipment, it is necessary to energize the boiler (add the heating medium to the appropriate starting pressure in the heating system), without forgetting to open the Mayevsky cranes to remove air. Modern boilers have automation, which independently monitors the state of the boiler. If necessary, inform about possible errors in the operation of the equipment, and subject to annual maintenance, it will work for many years. 90003 90196 90002 90198 Setting up a modern boiler with an electronic control unit, connecting smoke exhaust systems and any repairs must be carried out only by specialists of service organizations.According to the law, only persons having a work permit with gas can repair gas equipment! Annually the boiler must be serviced. 90199 90003 90201 90002 What to do if there is no boiler yet 90003 90002 First you need to determine what is needed for the boiler: only for heating or for heating hot water. Choose a model — single-circuit or two-circuit. Understand what area, taking into account future extensions, is planned to be heated, where it is planned to divert combustion products, how the boiler should behave in your absence.90003 90002 Recently, wall-mounted gas boilers have been very popular. They are a small boiler house — finished), a product that must be adapted for a particular heating system during installation and first start-up. To calculate the boiler output, use the following proportion: 1kW of power at 10 m 90098 2 90099 area. With calculation of capacity for water heating, it is necessary to take into account the number of consumers and points of draw-off. 90003 90002 Approximately, to wash the dishes, you need 6-7 l of hot water per minute, and on the shower — 11-12.In the market there are models producing up to 20 l / min. Pay attention to the speed of DHW heating and the technology by which the boiler operates silently. By the way, the built-in programmer can save a lot on energy resources (when you are not there, the boiler lowers the temperature by itself, saving gas). 90003 90002 When selecting smoke removal systems and providing airflow to the boiler, pay attention to the insulated coaxial kits. They have proven themselves at negative temperatures: they prevent icing of condensate and ensure stable operation of the boiler even at -50 ° C.If the length of the smoke exhaust pipe is more than 5 m, a heated separate system can be used, which will also prevent condensation inside the room. 90003 90002 Choose the boiler equipment trust professionals. They will make a calculation, recommend the equipment, make up the project and ensure the start of the equipment. 90003 90070 90004 WALL-MOUNTED BOILERS FOR HEATING A COUNTRY HOUSE: ADVICE AND FEEDBACK 90005 90002 The demand for gas boilers for heating systems in Russia remains constant, despite the crisis.Experts explain this by the fact that in addition to new construction there is a need to replace the old equipment. A gas boiler — this is a basic necessity, and few people risk pulling with his replacement 90003 90002 It is generally accepted that the service life of expensive floor boilers with a massive cast-iron heat exchanger is 25-30 years. Most of the same modern models (both floor and wall mounting) it is smaller, about 8-10 years. But the cost of such devices is much lower. Thanks to this, the devices remain accessible to most of the population.Thus, the most inexpensive boilers produced in the CIS can be purchased, for example, for 10-15 thousand rubles. True, these will, as a rule, be models not very sophisticated from a technical point of view — bulky (almost all for floor mounting), not fully automated. But they are quite suitable for replacing old domestic floor-standing boilers such as AGN 120, and therefore they have a steady demand. 90003 90002 However, over the past two decades, many houses have appeared, equipped with newer and more perfect gas boilers.These are basically models for wall mounting. They are equipped with burners and heat exchangers of improved design that allow the development of sufficient power for heating of 150-200 m2 mansions, which were previously thought to be heated exclusively with floor-mounted boilers. More than half of these boilers are dual-circuit, adapted not only for heating, but also for the preparation of hot water for the DHW system. Now a two-circuit wall-mounted boiler of well-known manufacturers (Ariston, BAXI, Bosch, Buderus, Kiturami, Protherm) can be purchased for 30-A0 thousand rubles, and the choice will be quite wide.90003 90225 WHEN POWER IS NEEDED 90226 90002 For the first time, the models of condensing boilers have become widespread in Russia, not even because of the economy, but because of the large capacity. Only these models in the wall version provided performance up to 60-90 kW. In the conditions of a large house and a small boiler room (or even its absence), only such boilers provided the necessary amount of heat and hot water. 90003 90105 WILL WE EXPECT GAS? 90106 90002 What do «manufacturers» offer us producers? Probably, the number one theme is the notorious condensation type boilers.Such equipment is now produced by all the leading manufacturers and is very popular in Europe. It can be said that conventional convection type boilers are considered obsolete there, and their complete replacement is only a matter of time. The secret is that the efficiency of condensing boilers can be 10-15% higher than convection boilers, due to which costs when buying more expensive condensers pay off in Europe for D-5 years. Plus, you get environmentally cleaner equipment, since the emission of harmful substances into the atmosphere in condensing boilers is small, several times lower than in traditional models.90003 90002 The increase in efficiency is ensured by the condensation of the vapors contained in the flue gas together with the combustion products. Smoke is cooled on the secondary heat exchanger (heat transfer medium from the return line of the heating system is fed to it) to about 55-57 ° C, water vapor condenses on the heat exchanger, and additional energy is added that gives an increase in efficiency. The condensation mode will work only in conditions when the temperature of the heat carrier in the return does not exceed 57 ° C and the greatest efficiency is achieved at low (30-35 ° C) coolant temperatures in the return.90003 90002 Why is the cost of condensing boilers noticeably higher than usual? In many respects this is due to the materials from which the heat exchanger is made. The resulting condensate contains acids and other aggressive chemical compounds that can completely disable, say, a heat exchanger from cast iron (it is no coincidence that the temperature of the flue gases in the convection boilers is specifically maintained at an outlet of not less than 1 DO-160 ° C). These parts in condensing boilers are made of stainless steel and similar, rather expensive materials.90003 90002 In Russia, the number of sales of condensing boilers is growing, but the pace is not high — hardly the volume of their sales is more than 5% of the total market. The reason for the lack of interest is the low cost of gas: in some European countries it costs the consumer 5-6 times more expensive than in Russia. Accordingly, the payback period of such boilers in Russia is too high, sometimes more than 10 years, which constitute the entire design life of the boiler itself. In addition, structurally condensing boilers are designed in such a way that the highest efficiency is achieved with small «European» frosts, and at strong (-20..- 25 ° C) it decreases, and the difference between the efficiency of condensing and convection boilers becomes small, somewhere around 5% (and the payback period becomes quite «indecent»). 90003 90002 But it seems that with the condensing boilers the same story will happen, as with energy-saving lamps. Gas will grow in price, equipment — on the contrary, will become cheaper, and little by little all users will switch to more economical equipment. Therefore, when planning a new house, it is better to immediately put into the project the possibility of placing a condensing boiler: how to equip the air supply to the boiler for normal operation and neutralize the condensate formed during operation.90003 90002 90003 90225 NOT SO SIMPLE! 90226 90002 Models of traditional (convection) boilers are also constantly complicated by design. So, today devices are demanded with the possibility of connecting weather-dependent automation. Depending on the settings, external temperature controllers allow the boiler to reduce or increase the heating intensity. Such possibilities are provided already in many convection boilers: in the series Vaillant turboFIT, Bosch Gaz 6000 W, Ariston Genus Premium Evo.90003 90002 In many models there are several modes of operation besides the main one. For example, in the WBN6000-35CR (Bosch) there are two additional modes: comfortable and Eco. In the comfort mode, the boiler constantly maintains the set temperature in the secondary heat exchanger, thereby reducing the waiting time for the selection of hot water. In the Eco mode, the heating to the set temperature is carried out only directly during the selection of hot water. 90003 90002 In most models, a closed combustion chamber is used, into which air is supplied by means of a special fan.This is a more complex version of the design, and, unlike traditional open cameras, it allows for better power management, which generally provides a higher efficiency. The disadvantage is that you need a constant connection to the electrical network. 90003 90002 Many convection boilers have an optimized control system. Increasingly, a variety of additional devices are used, such as remote controls — they are completed, say, the Atmo and Deluxe (Navien) series. And in the Smart (Navien) series, you can use a smartphone or a tablet as a control panel.90003 90002 90198 OPINION OF THE SPECIALIST 90199 90003 90002 What limits the spread of condensing boilers? First, they are quite expensive. The difference in price can make and 30, and even 100%. But keep in mind that to the price of the boiler you need to add the cost of purchasing and installing a gas removal and smoke removal system. For condensing boilers, these systems are much cheaper, so the «turn-key» price for the end customer will be comparable. Secondly, for the connection of condensing boilers, a low-temperature heating system is required.The maximum efficiency can be achieved only with the use of water-heated floors. However, the laboriousness of installation, the likelihood of pipeline leakage and the unquenchable belief in the exclusivity of radiator heating does not allow the warm floors to gain popularity among consumers. 90003 90002 SERGEY CHERNOV, MANAGER ON THE PRODUCT «VAYLANT TRUP RUS» 90003 90002 90198 HOW MUCH CIRCUITS DO YOU NEED? 90199 90003 90002 Quite often people choose a double-circuit boiler, believing that only such a device can handle both heating and hot water supply at home.This is not quite so, sometimes a single-circuit boiler is even more preferable. For example, if you have a large family and four or five pumping points. In this case, the best solution will be to buy a boiler and a separate boiler, since a two-circuit model can not cope with the intensive load. But if you have a family of two or three people and one or two points of water, the double-circuit boiler will be enough. 90003 90002 90003 90070 90270 90004 Popular and reliable producers of gas boilers 90005 90058 90059 90055 Ariston 90056 90060 90059 90055 Ferroli 90056 90060 90059 90055 Valliant 90056 90060 90059 90055 Viessmann 90056 90060 90059 90055 Junkers 90056 90060 90059 90055 Buderus 90056 90060 90059 90055 Navien 90056 90060 90059 90055 Beretta 90056 90060 90059 90055 Baxi 90056 90060 90059 90055 Daewoo 90056 90060 90059 90055 Gas boilers of the Zhukovsky plant 90056 90060 90059 90055 Protherm 90056 90060 90069 90323 90324 TOOLS FOR MASTERS AND MASTERS, AND HOME GOODS ARE VERY CHEAP.FREE SHIPPING.
