What Is A System Boiler?

A system boiler links with a hot water storage cylinder to provide a home with central heating and hot water. It does this by taking cold water directly from the mains (instead of a cold water storage tank) and heating it via an internal heat exchanger, this transfers gas energy to water.

The hot water is then moved to the hot water cylinder for storage.

Unlike some regular boilers, such as oil or heat only, that use bulky external components, with a system boiler the majority of components are integrated within the appliance.

The only external part is the aforementioned hot water storage cylinder; This is a much smaller unit than some of the other hot water storage tank systems used by regular boilers, these tend to eat up an excessive amount of loft space.
