What is a combination boiler (Combi Boiler)?
The major difference between a combi boiler and any other type of boiler is that it eliminates the need to store hot water, meaning no hot water cylinder in the airing cupboard. It is both a high-efficiency water heater and central heating boiler, combined (hence the name combi) within one compact unit which usually sits in the kitchen or utility room. The Combination Boiler results in space saving from the fact there is no hot water storage cylinder, cold water storage, cistern or other familiar components of a regular (conventional) heating system.
