Sometimes referred to as ‘sealed system’ boilers, a system boiler works in the same way as a conventional boiler, storing hot water separately, in a water cylinder.

With many of the individual components of the heating and hot water system built into a system boiler, installation is usually faster and more efficient when compared to other types of boiler. Great for homes that need to have hot water in more than one place at the same time, system boilers heat the central heating system directly.

How does a system boiler work?

Removing the need for a feed and expansion cistern, system boilers pump hot water from the boiler through the heating system to the radiators and hot water cylinder.
