Advantages of Condensing Boilers
Condensing boilers are super clever, super at saving energy and super at saving money.
Here are the best condensing boilers of 2021, as according to Boiler Comparison website Let’s heat recent review:
Did you know that every year, more than 1 million new boilers are installed into UK homes?
That’s an incredible amount of boilers, and thanks to the introduction of ‘Boiler Plus’ legislation back in 2005, all new installs are now condensing boilers that are a huge improvement on the inefficient non-condensing models of the past.
But what exactly are condensing boilers?
Condensing boilers are water heaters fuelled by gas or oil. These boilers achieve a high-efficiency level (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.
This condensed vapour leaves the system in liquid form, via a drain.
In many countries, the use of condensing boilers is compulsory or encouraged with financial incentives.
And how do you know why condensing boiler to choose?
