A combi boiler provides heating and hot water directly from the boiler. A combi boiler is both a high efficiency water heater and a central heating boiler, combined within one compact unit. Therefore, a separate hot water cylinder is not required providing space-saving in the home.

Combis are like standard unvented boilers but they have a second heating circuit, which is what gives you the instant hot water whenever you need it. If fed directly from the main water supply to the heat exchanger, the combi boiler can have an unlimited hot water supply as long as the boiler is firing.

Key Benefits

• Saves space in a home (does not require separate tanks for hot and cold water)
• Reduces operation and installation cost
• No hot water cylinder, loft tank, or pipework
