Types of Boilers

Condensing Boilers: All new gas or oil boilers installed must be a condensing boiler.Condensing boilers are highly efficient thereby using less fuel and having lower operating costs than other gas or oil boilers. The higher efficiency levels are made possible by extracting heat contained in the combustion gases and vapours capturing the energy which would otherwise be wasted to the atmosphere.

Combi Boilers: Combination boilers provide instant hot water and heating as water for the heating system and the provision of hot water is combined. This removed the need for a hot water

Boiler Lifespan

Oil and gas boilers have an approximate maximum lifespan of 15 years. Boilers of that age would typically have an efficiency of less than 70% so if you have an older boiler it is time to consider replacing it with a new high efficiency model which will save on fuel costs and avoid having to content with a breakdown. High efficiency boilers have an efficiency of over 90% which is estimated to represent an actual fuel saving of 25% over an older low efficiency model.
