The efficiency of a boiler is assessed by their ability to turn fuel into heat. From now on all newly installed boilers must be condensing boilers as they typically rate around 90% efficient.

To dispel some of the myths surrounding condensing boilers, here are some facts about installation:

• Your old boiler can be replaced with a condensing type be it floor standing or wall mounted - there are also different fluing options available

• With regard to siting the condensing boiler this will be much the same as a conventional boiler.

• Condensing boilers are available as system boilers, regular boiler and combination boilers. They can be installed in fully pumped systems as well and all with the same ease as a conventional boiler

• When installing a condensing boiler as a replacement, there is no need to change the current installation, as the improved efficiency will still be met. Over-sized radiators will not increase this efficiency enough to warrant any costly changes. Typically a condensing boiler will have an efficiency of 83-92% in comparison to a conventional boiler of 75% or older boilers of 55-60%
