Type of combi boilers we install

Combi (instantaneous) boiler is the most widely used combi boiler type and directly heats incoming mains cold water to supply your taps, showers and other hot water points.

Combi (storage) boiler is a variant of the Instantaneous combi boiler type above and is designed to give you better performance through the internal storage of heated water. The stored water also can give you better initial water supply from cold water mains on first turning on the tap. Once the stored heat has been used, this boiler will tend to operate as an ‘instantaneous’ type. Dependent upon the make and model, the improvement in heated water delivery will depend upon the size of water store, and this can vary widely.

Combi (storage condensing) boiler operates in principle as a ’storage’ type but at higher efficiencies.

Combined Primary Storage Unit (CPSU) – This is a special category of storage combi which will incorporate a very large water store allowing a high water flow rate to taps and other draw off points and to quickly heat radiators before the water store is used.
