A system boiler is the term for a heat-only boiler. System boilers are a type of condensing boiler which occupy the middle ground between combi boilers and the regular boilers.
Unlike combi boilers which provide almost instantaneous how water, system boilers and regular (conventional) boilers work on the principle of heating stored water in a copper cylinder (usually in the airing cupboard). A system boiler will provide heating together with the power to heat water to be stored within the cylinder as part of a sealed system. Notwithstanding this system boilers differ from regular boilers in some fundamental respects.
Compact installation
The key difference with a system boiler is that all the major components are built in to the boiler. By building in components, which most other boilers situate outside the unit, system boilers can provide a compact and attractive installation. One noticeable difference is that a feed and expansion tank in the attic is no longer needed. This can save you space and the system has fewer components to maintain.
Building the major individual components of the heating and hot water system in to the system boiler means that installation is quicker, neater, easier and more efficient.
Loft space not required
As noted the header or feeder tank required by a regular boiler to continually feed water to your central heating system is not required. System boilers take a direct feed from the cold water mains and store water in a small tank built into the boiler. Accordingly space is freed in your loft which may enable you to use it for alternative purposes.
Hot water cylinder retained
The storage of hot water in the hot water cylinder means that the boiler is less dependent upon a flow of water from the cold water mains and can be used in areas where the water pressure is too low for a combi boiler to be used.
