The most popular type of boiler. A combi boiler only heats water when you need it, running the hot tap or when your shower is being used, providing maximum efficiency. Hot water flows to your taps at the pressure of your mains supply, so you can enjoy a hot powerful shower without the need for a pump.
For households that require more available hot water to cater for multiple bathrooms and central heating a system boiler could be the perfect choice.
The system boiler provides hot water to your taps and feeds your radiators via a pump. Hot water stored in a sealed storage cylinder.
System boilers are reliable, versatile and highly efficient.
