Get to know the different boiler types you can get

Combi boilers

The most popular type of boiler

Combi boilers are the most popular and cost-effective choice for many homes. They provide heating and hot water from one compact unit, heating water directly from the mains whenever a tap is turned on.

Regular boilers

For busier family sized homes

Regular boilers work with both
a hot water cylinder and a cold-water tank in the loft. They’re ideal for older homes with existing vented heating systems, especially where the pipework or radiators may not handle the higher pressure of a modern combi or system boiler.

System boilers

Common in larger newer homes

System boilers store hot water in a cylinder but store most other components within the boiler itself. They’re perfect for homes with multiple bathrooms where hot water may be needed in several places at once.

Why Upgrade to a New Boiler?a New Boiler?

Replacing an outdated boiler

long-term benefits.
