What is a combi boiler?

A combi (short for combination) boiler is the most compact option because it generates both your heating and hot water from a single unit, usually wall hung. With a combi boiler, there’s no need for a separate hot water tank.

How do combination boilers work?

Combi boilers are connected to the mains cold water supply and can heat water on demand. They burn fuel when you ask for hot water and have an integral heat exchanger that then gets hot enough to instantaneously heat the cold water from the mains supply as it flows over it.

Guaranteed -10 years peace of mind subject to annual boiler service after your first year (not included).
