Condensing Combination Boilers

Combination boilers, often referred to as combination boilers, provide hot water for your taps from within the boiler. Combine this with central heating, combi boilers are easily the most popular boiler type, accounting for over 50% of all new boiler sales within the UK.
Using a ‘combi’ the cold water feed tank and the cylinder is not required providing more space in your home.

Other factors to be considered
One small disadvantage is that although a continuous flow of hot water is constantly available, the hot water flow rate from some combi boilers is not likely to be as good as with a traditional storage cylinder, particularly in Winter.
Because the boiler is fed directly with mains cold water, it is important to establish that the minimum design water pressure is available otherwise the hot water performance will suffer. For this reason a combi boiler is not always suitable and a site survey is often required.

There are five types of combi boiler

A combi (instantaneous) boiler is the most widely used type and directly heats incoming mains cold water to supply hot water to your taps, showers and other hot water points.
A combi (instantaneous condensing) boiler operates as an ‘instantaneous’ boiler but at somewhat higher efficiencies than the standard combi boiler.
A combi (storage) boiler is a variant of the Instantaneous type above and is designed to give you better hot water performance through the internal storage of hot water. The stored hot water also can give you better initial hot 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 hot water delivery will depend upon the size of hot water store, and this can vary widely.
A 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 hot water flow rate to taps and other draw off points and to quickly heat-up to radiators before the hot water store is used.
