What size boiler do I need?
Whether you’re in a one-bedroom flat or a four-bedroom house, it’s important to consider the boiler size you need to have hot water and heating when you need it.
Importantly, boiler size refers to the output in kW rather than the physical size of the boiler. The higher the heating output the more hot water it produces, however if you have too large an output for your home then you’ll be wasting energy.
We’ve put together a handy guide so you can see what size boiler is right for your home.
Combi boilers.
Combi or combination boilers are stand-alone units that heat water directly from the cold mains. They’re ideal for small to medium sized homes.
Regular boilers.
Regular boilers come with a cold water tank and a hot water cylinder, so will take up more space in your home than a combi boiler. They work well with older heating systems and are suitable for larger homes that need more hot water.
System boilers.
System boilers have a separate hot water cylinder which provides heating and hot water. You won’t need a cold water tank in the loft. System boilers are great for larger homes, for example if you have multiple bathrooms or underfloor heating.
How does the type of fuel I use affect my boiler choice?
You can get combi, system and regular boilers available in a range of different fuels, including:
Gas.
Oil.
Liquified petroleum gas (LPG).
Additionally, different types of fuels can be more effective with certain types of boilers. For example, gas combi boilers tend to cost less to run than oil-fired boilers. Speak to one of our heating engineers if you have any questions.
