Frequently Asked Questions:

What is a High Efficiency Condensing Boiler?

High efficiency condensing boilers convert more than 88% of their fuel into heat, compared to 78% for conventional types. Replacing your old boiler with a new HEC boiler will save you around a third on your heating bill straight away. By law, from the 1st April 2005 onwards, all new gas boilers fitted in England and Wales must be HEC boilers (with a few exceptions depending on suitability). HEC boilers can be easily fitted to most new and old heating systems.

Is my boiler a High Efficiency Condensing Boiler?

If it’s 10-15 years old then it probably isn’t. Boilers are rated according to how much of the fuel they consume is converted to heat, as a percentage. These ratings are from A-G, A-rated boilers being more than 90% efficient. Only A or B rated boilers (having efficiencies above 86%) carry the energy saving recommended logo.

What about Heating Controls?

To get the most out of your new High Efficiency Boiler think about combining it with new heating controls. Heating controls manage how central heating systems react to changes in temperature, provide different levels of heat in different rooms and switch hot water on and off at times specified by the homeowner. Heating controls will pay for themselves in less than five years. The more control, the greater the savings on energy and money, as much as 17% on the average heating bill.
