This does not mean that you’ll need a boiler that takes up a lot of space, however. When referring to boiler size throughout this article, we will actually be focusing on its output size in kilowatts (kW).</p>\n\n\n\n<h3 id=\"How-many-kW-boiler-for-a-4-bedroom-house\">How many kW boiler for a 4-bedroom house?</h3>\n\n\n\n<p>While there is no single correct answer for which size of boiler is best for a 4 bedroom house, there are some simple calculations we can use to provide a decent estimate. The size of the boiler you require does not depend on the number of bedrooms you have. It is actually dictated by the number of <a href=https://www.greenmatch.co.uk/"https://www.greenmatch.co.uk/blog/2015/07/central-heating-radiators/" title=\"Central Heating Radiators\">radiators</a> within your home.</p>\n\n\n\n<p>A good rule to follow when calculating what output size a boiler will need to be to heat your home effectively is to allow 2kW for each radiator in your home. This will give you a good idea of what kind of boiler will be best suited to your home. For example: A home with 20 radiators will require a boiler with a central heating output of around 40kW.</p>\n\n\n\n<p>The only way to find out exactly which boiler will be best for your 4 bedroom home is by getting expert advice from a professional installer. However, finding the right installer can prove to be difficult itself. Not only do you need to find boiler installers near you, but you also need to vet them, and compare several quotes to ensure you aren’t overcharged.</p>\n\n\n\n<p>Fortunately, we can make this process considerably less painful for you. Simply click the button below and answer some simple questions. Then we’ll find up to 3 trusted boiler installers in your area and provide you with free comparison quotes from them. Then all you need to do is pick the deal that’s best for you. You don’t have to accept any of the quotes you receive.</p>\n\n\n\n\n\n\n<CtaBlock key=\"block_64d0c4687dbda\"\n class=\"wp-macro\"\n title='Get your best deal'\n subTitle='Quickly compare 3 FREE quotes'\n usps='<ul class=\"ul1\">\n<li class=\"li1\">Quotes from local engineers</li>\n<li class=\"li1\">Payment by finance available</li>\n<li class=\"li1\">Save up to £1080</li>\n</ul>\n'\n :uspsImage='{\"ID\":67205,\"id\":67205,\"title\":\"person\",\"filename\":\"person.png\",\"filesize\":53348,\"url\":\"https:\\/\\/cdn.greenmatch.co.uk\\/cdn-cgi\\/image\\/format=auto\\/2\\/2023\\/03\\/person.png\",\"link\":\"https:\\/\\/www.greenmatch.co.uk\\/cta-block\\/solar\\/person\",\"alt\":\"\",\"author\":\"1\",\"description\":\"\",\"caption\":\"\",\"name\":\"person\",\"status\":\"inherit\",\"uploaded_to\":67204,\"date\":\"2023-03-24 15:51:17\",\"modified\":\"2023-03-24 15:51:17\",\"menu_order\":0,\"mime_type\":\"image\\/png\",\"type\":\"image\",\"subtype\":\"png\",\"icon\":\"https:\\/\\/www.greenmatch.co.uk\\/wp-includes\\/images\\/media\\/default.png\",\"width\":124,\"height\":277,\"sizes\":{\"thumbnail\":\"https:\\/\\/cdn.greenmatch.co.uk\\/cdn-cgi\\/image\\/format=auto\\/2\\/2023\\/03\\/person-124x150.png\",\"thumbnail-width\":124,\"thumbnail-height\":150,\"medium\":\"https:\\/\\/cdn.greenmatch.co.uk\\/cdn-cgi\\/image\\/format=auto\\/2\\/2023\\/03\\/person.png\",\"medium-width\":124,\"medium-height\":277,\"medium_large\":\"https:\\/\\/cdn.greenmatch.co.uk\\/cdn-cgi\\/image\\/format=auto\\/2\\/2023\\/03\\/person.png\",\"medium_large-width\":124,\"medium_large-height\":277,\"large\":\"https:\\/\\/cdn.greenmatch.co.uk\\/cdn-cgi\\/image\\/format=auto\\/2\\/2023\\/03\\/person.png\",\"large-width\":124,\"large-height\":277,\"1536x1536\":\"https:\\/\\/cdn.greenmatch.co.uk\\/cdn-cgi\\/image\\/format=auto\\/2\\/2023\\/03\\/person.png\",\"1536x1536-width\":124,\"1536x1536-height\":277,\"2048x2048\":\"https:\\/\\/cdn.greenmatch.co.uk\\/cdn-cgi\\/image\\/format=auto\\/2\\/2023\\/03\\/person.png\",\"2048x2048-width\":124,\"2048x2048-height\":277}}'\n buttonText='GET QUOTES NOW'\n buttonDescription='It only takes 30 seconds'\n optimizeText='Optimise your home and save the planet'\n :optimizeImage='{\"ID\":67392,\"id\":67392,\"title\":\"earth-globe-square\",\"filename\":\"earth-globe-square.svg\",\"filesize\":8466,\"url\":\"https:\\/\\/cdn.greenmatch.co.uk\\/cdn-cgi\\/image\\/format=auto\\/2\\/2023\\/03\\/earth-globe-square.svg\",\"link\":\"https:\\/\\/www.greenmatch.co.uk\\/cta-block\\/boilers\\/earth-globe-square\",\"alt\":\"Earth globe icon\",\"author\":\"48\",\"description\":\"\",\"caption\":\"\",\"name\":\"earth-globe-square\",\"status\":\"inherit\",\"uploaded_to\":67362,\"date\":\"2023-03-31 08:31:49\",\"modified\":\"2023-03-31 08:32:07\",\"menu_order\":0,\"mime_type\":\"image\\/svg+xml\",\"type\":\"image\",\"subtype\":\"svg+xml\",\"icon\":\"https:\\/\\/www.greenmatch.co.uk\\/wp-includes\\/images\\/media\\/default.png\",\"width\":1,\"height\":1,\"sizes\":{\"thumbnail\":\"https:\\/\\/cdn.greenmatch.co.uk\\/cdn-cgi\\/image\\/format=auto\\/2\\/2023\\/03\\/earth-globe-square.svg\",\"thumbnail-width\":150,\"thumbnail-height\":150,\"medium\":\"https:\\/\\/cdn.greenmatch.co.uk\\/cdn-cgi\\/image\\/format=auto\\/2\\/2023\\/03\\/earth-globe-square.svg\",\"medium-width\":300,\"medium-height\":300,\"medium_large\":\"https:\\/\\/cdn.greenmatch.co.uk\\/cdn-cgi\\/image\\/format=auto\\/2\\/2023\\/03\\/earth-globe-square.svg\",\"medium_large-width\":768,\"medium_large-height\":1,\"large\":\"https:\\/\\/cdn.greenmatch.co.uk\\/cdn-cgi\\/image\\/format=auto\\/2\\/2023\\/03\\/earth-globe-square.svg\",\"large-width\":1024,\"large-height\":1024,\"1536x1536\":\"https:\\/\\/cdn.greenmatch.co.uk\\/cdn-cgi\\/image\\/format=auto\\/2\\/2023\\/03\\/earth-globe-square.svg\",\"1536x1536-width\":1,\"1536x1536-height\":1,\"2048x2048\":\"https:\\/\\/cdn.greenmatch.co.uk\\/cdn-cgi\\/image\\/format=auto\\/2\\/2023\\/03\\/earth-globe-square.svg\",\"2048x2048-width\":1,\"2048x2048-height\":1}}'\n bottomTitle='Call us to get quotes'\n bottomSubTitle='We will get you the best deal'\n phone='0330 808 0405'\n ctaBlockBackgroundColorStart=''\n ctaBlockBackgroundColorEnd=''\n ctaBlockTitleColor=''\n ctaBlockSubtitleColor=''\n ctaBlockUspImageColor=''\n ctaBlockBottomTextColor=''\n ctaBlockBottomBackgroundColor=''\n ctaBlockPhoneTextColor=''\n />\n\n\n\n\n<p></p>\n</div></div>\n\n\n\n<div class=\"wp-container-5 wp-block-group\"><div class=\"wp-block-group__inner-container\">\n<h2 id=\"What-Boiler-is-Suited-for-Your-4-Bedroom-House\">What boiler is suited for your 4-bedroom-house?</h2>\n\n\n\n<p>As the average 4 bedroom house has between 10 and 15 radiators, you will most likely require a boiler with an output rating of around 20 to 30 kW.

We would only recommend replacing an existing regular boiler with a new one.</p>\n\n\n\n<p>Here are the top 3 regular boilers for a 4 bedroom house:</p>\n\n\n\n<h4>Worcester Bosch Greenstar 8000 regular boiler</h4>\n\n\n<div class=\"wp-block-image no-shadow\">\n<figure class=\"alignright is-resized\"><img loading=\"lazy\" src=https://www.greenmatch.co.uk/"https://cdn.greenmatch.co.uk/cdn-cgi/image/format=auto/2/2022/10/worcester-bosch-8000-life-boiler.png/" alt=\"Worcester Bosch Greenstar 8000 regular boiler\" class=\"wp-image-62730\" width=\"157\" height=\"200\" /></figure></div>\n\n\n<p>Greenstar 8000 regular boilers are only available in the high gloss white variant. However, they are available in a wide range of output sizes from 30 to 50kW too. This means that they can easily heat a 4 bedroom property, and could even heat a home with more than 25 radiators if required.</p>\n\n\n\n<p>Key features:</p>\n\n\n\n<ul><li>Robust and lightweight design.</li><li>Intelligent filling system.</li><li>Wireless connectivity.</li><li>LPG (liquified petroleum gas) compatible.</li></ul>\n\n\n\n<h4>Vaillant ecoTEC Plus regular boiler</h4>\n\n\n<div class=\"wp-block-image no-shadow\">\n<figure class=\"alignright is-resized\"><img loading=\"lazy\" src=https://www.greenmatch.co.uk/"https://cdn.greenmatch.co.uk/cdn-cgi/image/format=auto/2/2022/10/vaillant-ecotec-plus-boiler.jpeg/" alt=\"Vaillant ecoTEC Plus regular boiler\" class=\"wp-image-62725\" width=\"124\" height=\"201\" /></figure></div>\n\n\n<p>The ecoTEC Plus regular boilers from Vaillant are available in outputs that go up to a maximum of 35kW.

energy bills by installing an energy efficient boiler We’ve helped over 500,000 homeowners reduce their carbon footprint What is the best boiler for a 4 bedroom house? Whether you are looking for a combi, regular or system boiler, you’ll need to get the right output size for your home. In this article we’ll cover what size boiler you will need, and help you to decide which boiler type is best suited to your 4 bedroom home. Your house and current heating system make your situation unique. If you would like customised information for your individual situation, you can compare up to 3 quotes to help you find a boiler installer that fits your needs. It is at no cost and is obligation-free. The size of your home will directly affect the size of the boiler you’ll require. This does not mean that you’ll need a boiler that takes up a lot of space, however. When referring to boiler size throughout this article, we will actually be focusing on its output size in kilowatts (kW). While there is no single correct answer for which size of boiler is best for a 4 bedroom house, there are some simple calculations we can use to provide a decent estimate. The size of the boiler you require does not depend on the number of bedrooms you have. It is actually dictated by the number of radiators within your home. A good rule to follow when calculating what output size a boiler will need to be to heat your home effectively is to allow 2kW for each radiator in your home. This will give you a good idea of what kind of boiler will be best suited to your home. For example: A home with 20 radiators will require a boiler with a central heating output of around 40kW. The only way to find out exactly which boiler will be best for your 4 bedroom home is by getting expert advice from a professional installer. However, finding the right installer can prove to be difficult itself. Not only do you need to find boiler installers near you, but you also need to vet them, and compare several quotes to ensure you aren’t overcharged. Fortunately, we can make this process considerably less painful for you. Simply click the button below and answer some simple questions. Then we’ll find up to 3 trusted boiler installers in your area and provide you with free comparison quotes from them. Then all you need to do is pick the deal that’s best for you. You don’t have to accept any of the quotes you receive. As the average 4 bedroom house has between 10 and 15 radiators, you will most likely require a boiler with an output rating of around 20 to 30 kW. You will also need to take the number of bathrooms into account as well. For a bit more information on which type of boiler will be best suited to your home, check the sections below for each different boiler type. A combi boiler is suitable for a 4 bedroom house, so long as it doesn’t have too much demand for hot running water. If your home has more than 2 bathrooms, you may find that even the best combi boilers will struggle to meet your hot water needs. If your home has 2 bathrooms or fewer though, a combi boiler could be a great choice. Here are the top 3 boilers with output ratings between 20 and 30kW. The ecoTEC Plus combi boiler is available in output sizes ranging from 25kW to 38 kW. This makes it more than capable of heating a 4 bedroom home effectively and efficiently. It has the following key features too: With a central heating output of between 25 and 32kW, the Vitodens 200-W combi boiler is perfect for heating a 4 bedroom home. It also has a number of key features which we’ve listed below: The Greenstar 8000 is not only available in output ranges of 30 to 35kW, it is also available in 2 high gloss colours (black or white). This means it can easily heat a 4 bedroom house and look good doing it. It has the following key features: For a 4-bedroom house you will need an 18kW to 43kW combi boiler depending on how many radiators you have. System boilers can be suitable for a 4 bedroom house with any level of hot water demand, so long as they are installed alongside a big enough hot water cylinder. They take up less room than a regular boiler, as they draw water directly from the mains with no need for a feed tank in the loft. We’ve provided our top 3 system boiler picks below: Available in output ratings of between 24 and 30kW, the Logic Max system boiler is perfectly suited to heating a property with 4 bedrooms and several bathrooms, depending on the size of hot water cylinder it is paired with. Some of its key features are: A great choice for homes with hot water, the Baxi Megaflo is available in a range of output sizes up to 32kW. It is compatible with the Megaflo Eco cylinder which can be used to provide a large supply of hot running water throughout your home. Key features: As well as being available as a combi boiler, the Vitodens 200-W can also be used as a system boiler. It is available in a 25kW and 32kW model, making it ideal for a home with 4 bedrooms. When it is combined with a hot water cylinder, the vitodens 200-W can easily provide sufficient hot water for homes with multiple bathrooms. Key features: As regular boilers combine with a hot water cylinder to provide hot running water, they are suitable for use in any 4 bedroom home with any amount of bathrooms. However, they do require a feed tank in the loft to provide them with water, which means they can take up a lot of space. We would only recommend replacing an existing regular boiler with a new one. Here are the top 3 regular boilers for a 4 bedroom house: Greenstar 8000 regular boilers are only available in the high gloss white variant. However, they are available in a wide range of output sizes from 30 to 50kW too. This means that they can easily heat a 4 bedroom property, and could even heat a home with more than 25 radiators if required. Key features: The ecoTEC Plus regular boilers from Vaillant are available in outputs that go up to a maximum of 35kW. This makes them suitable for use in houses with 4 bedrooms or up to 18 radiators. It includes the following key features: With a maximum output range of 30kW, Ideal Logic Max Heat boilers are easily capable of heating a 4 bedroom home. They are easy to use too, with a large digital colour display.
