Safe shopping by GeoTrustBoth a system boiler and a regular boiler work on the principle of stored hot water unlike the combi boiler. Although the system boiler stores hot water similarly to the regular boiler, they are still different in some significant respects.
The system boiler is very efficient for many reasons, most of the important individual components to the boiler are already built in which means the installation will be easier, quicker and it will look a lot tidier.
Having a system boiler means that space will be saved. It also includes an expansion vessel meaning that there is no need for a feed and expansion tank in the loft area.
