New System Boiler

A System boiler heats your central heating system directly and produces hot water for your cylinder.

They work just like a Regular (Conventional) boiler on the principle of stored hot water, however, a System boiler has some distinguishing features.

Installation is quicker, neater, easier and more efficient than it is with a Regular boiler, due to many of the major individual components being built into a System boiler. By building-in components, which most other boilers situate outside, the unit can provide a compact and attractive installation.

Another noticeable difference is there’s no need for a feed and expansion cistern. This can save you additional space and means the system has fewer components to maintain.

How Does a System Boiler Work?

With a System boiler the hot water is pumped through to the radiators and the hot water cylinder, resulting in a fast response and more economical running costs.
