Gas Combi Boilers

A combi or combination gas boiler is an energy efficient water heater and central heating boiler all in one. There is no need for a separate cylinder or cold water storage tank when using a combi boiler, as hot water is delivered directly and instantly at mains pressure. Combi boilers save on installation costs and save you space too!

You can expect to pay anything from £600 up to £1500 for a combi gas boiler, but the costly market-leading brands such as Vaillant and Worcester Bosch have similar or identical inner parts to lower-priced models a lot of the time. Call our sales team to make sure you're getting the best deal.
