Q What kind of fuel does your boiler use?

Which type of boiler is best for a medium sized house?

combi boiler

Most houses in the UK have about 2-3 bedrooms. A key factor in deciding what boiler you’ll need to install is considering the number of bathrooms your house has.

For a medium-sized house, which generally has about 1 or 2 bathrooms, we recommend a standard combi boiler.

If your house has three bathrooms or more, you’d be better off installing a system boiler or a conventional boiler, as these will be able to provide more hot water at once.

The key difference between these and a combi boiler is that they have a hot water cylinder to store hot water.

Combi boilers, however, have no separate hot water cylinder and have all the parts needed to heat your home inside of the boiler.

This is one reason why this boiler type is popular for medium-sized houses; it saves space.

Another reason why combi boilers are so popular is their energy efficiency rating. Modern boilers have an efficiency rating of 94%, which means that for every £100 you spend on heating, an actual £94 goes directly towards heat. Only about £6 is lost in the heating process.

Every boiler loses some heat in the form of waste gases but combi boilers are highly efficient compared to regular, older models. Installing a combi boiler could really help you save money on your heating bill.

Why are combi boilers best for 3 bed homes?

no hot water tank

Not only are combi boilers efficient, but they are also perfectly suitable to cater for 3-bedroom houses.

On a cold winter day, you would generally need about 4kW to 8kW, depending on how old and well insulated your house is. On warmer days, this would be around 1kW to 2 kW.

Generally, combi boilers have an output of about 24kW to 38kW for hot water and about 18kW for heating. This perfectly suits the needs of anyone or two-bathroom house.

Note that a combi boiler wouldn’t be sufficient for a house with more than two bathrooms. If you have more bathrooms than this, choose a model that suits your hot water requirements, such as a system boiler.

FAQs

How many kilowatts do I need for a 3 bedroom house boiler?

faqs

The average kW you need for a 3-bedroom house is lower than you might think. On a cold winter day, this would be about 4 to 8 kW.

If your house is newer and better insulated, this will be lower and vice versa. For a warmer day, for example during spring or autumn, your house would need about 1-2 kW.

Combi boilers have a kW output of about 24kW up until 38kW for hot water production. For heating, this is about 18kW. This is more than enough to heat your 3-bedroom home and provide enough hot water.

Can a combi boiler be used in a large house?

We advise installing a combi boiler in a 3-bedroom house with 1 or maximum 2 bathrooms. For a larger house with multiple bathrooms, there are other more suitable boilers, such as regular boilers or system boilers.
