A combi boiler (or combination) heats water whenever a hot tap or shower is turned on, removing the need to find space for a tank in the loft or the risk of a storage cylinder running cold. Water is fed from the mains so the water pressure is generally better than with traditional boilers.
Combi boilers are now the most popular type of boiler for gas central heating and domestic hot water production in the UK. Reliable, durable, convenient and easy to install, gas combi boilers are also economical to run. They produce an endless stream of hot water, whenever it is needed and only when it is needed.
