System Boiler

A System Boiler is a high efficiency boiler that generates heat for the central heating system and hot water indirectly via an indirect hot water cylinder. A system boiler also contains many of the features that would be found external of a regular or combi boiler within the boiler such as the expansion vessel and heating pump. Also a system boiler is fitted to a sealed unvented system which is more efficient than an open vented system.

There are a number of System Boiler models available that run on different fuel types including Gas, LPG, Oil and Electric with different heating output options of most models. Also most System Boilers are also Condensing System Boilers which are more energy efficient than non-condensing equivalents helping household reduce their fuel costs and carbon emissions.
