Types of boiler

The first factor to consider when buying a new boiler is what type of boiler you have and need. There are three main types of boiler that are commonly found in UK households:
Combi boiler – combi boilers are the most common types of boiler found in the UK. They are perfect for smaller families with a house with only one bathroom, and a smaller water and heating usage.
System boiler – System boilers use water cylinders to store hot water used in the heating system. System boilers also get the water directly from the mains, unlike conventional boilers.
Conventional boiler – Conventional boilers are like system boilers in that they both use cylinders to store hot water. However, conventional boilers do not get their water directly from the mains.

Needs and house size

The size of your house and how much you will use the heating system will impact which boilers will be best suited for your house. For example, a combi boiler is best suited for smaller families and one bathroom due to receiving water directly through the mains. System boilers are able to handle larger heating and water demands, which is ideal for larger families, or for houses with more than one bathroom.

Boiler size

Boiler size refers to how many kiloWatts (kW) a boiler can produce. Depending on how many radiators your house has, and what type of boiler you have will impact what size boiler you should go for. Please note that you should never get a boiler that is too powerful: it will not make your boiler more efficient, it will instead waste the fuel.

Combi boilers:
-Up to 10 radiators: 24kW – 27kW
-10 – 15 radiators: 28kW – 34kW
-15 – 20 radiators: 35kW – 42kW

System and Conventional boilers:
-Up to 10 radiators: 12kW – 15kW
-10 – 15 radiators: 18kW – 24kW
-15 – 20 radiators: 30kW – 40kW

In conclusion, there are a variety of factors to consider when purchasing a new boiler, including the type of the boiler, the size of the boiler and your house’s water and heating needs.
