Building regulations now insist that all new boilers installed in any domestic home should be high efficiency condensing boilers. Condensing boiler prices vary depending on size and other features, but the price is well worth the benefits. With 60% of your home energy costs being directly linked to the boiler you use, it is well worth installing a high efficiency boiler to hopefully lower your bills.

What is a condensing boiler?

High efficiency condensing boilers are a great choice for those who care about the environment (every year a condensing boiler could save up to 1.7 tonnes of carbon dioxide). Condensing boilers are able to fully utilise the heat they generate from burning fuels, making them on average 25% more efficient than non-condensing models.

Michael Hanson says:

Interesting, but one page ( says a condensing boiler is u.t. 12% more efficient and the next page ( says 25% on average more efficient!
Then the Energy Saving Trust says a condensing boiler can save up to £300 – per week, per year or during the life of the boiler?
Why am I so sceptical over these claims?

Good pick Michael. I have checked the sources and have updated the article. The correct number is 25%. I guess it was a typo error. Sorry about that. Regarding how much could you save? – You can save £300 per year. I have now updated that as well. Thanks again.
