System Boilers

Much like a conventional boiler, a system boiler operates using stored hot water. However, there are important differences between the two.

A system boiler contains many major components of the heating and hot water system already built in. This allows installation that is not only faster, but easier, tidier and more efficient.

Unlike a regular boiler, a system boiler pumps the hot water straight through the heating system to the radiators and hot water cylinder, reducing the amount of time it takes for the dwelling to heat up and as such, reducing running costs.

There is no need for a feed and expansion cistern with a system boiler.
