Which type of boiler do I need?

How do I decide which type of boiler best suits my needs?

There are 3 different types of boiler:

Combi boiler (or ‘combination’ boiler)
Regular boiler (often also referred to as a ‘traditional’ or ‘conventional’ boiler)
System boiler

Combi boilers provide heating and hot water directly from the boiler.

Regular and system boilers heat your central heating system directly and produce hot water for your cylinder.
