Combi Boilers

A combi (or combination) boiler provides heat for central heating and heats water instantly whenever a hot tap or shower is turned on. Water is fed from the mains, so the water pressure is generally better than with traditional boilers and there’s no need for a tank in the loft. Condensing combi boilers are the most popular type of boiler in the UK. They’re reliable, convenient, easy to install and economical – producing an endless stream of hot water, whenever it’s needed. However, if you have a high hot water demand, you might wish to consider a system boiler with an unvented cylinder. Combi boilers are generally available in 24 to 40kW outputs. We have a huge range of the leading brands, offering you the best deals on boiler prices. To help you choose, we’ve compiled a list of our top ten selling combi boilers.
