Rod Pilcher, The Boiler Man, explains how a condensing boiler can save a third on your heating bills, and help sell your house.
A high efficiency condensing boiler works on the principle of recovering as much as possible of the waste heat which is normally rejected to the atmosphere from the flue of a conventional (non-condensing) boiler. The best high efficiency condensing boilers convert more than 90% of their fuel into heat, compared to 78% for conventional types.
This is accomplished by using a larger heat exchanger or sometimes two heat exchangers within the boiler which maximises heat transfer from the burner as well as recovering useful heat which would normally be lost with the flue gases. When in condensing mode (condensing boilers do not condense all the time) the flue gases give up their 'latent heat' which is then recovered by the heat exchanger within the boiler. As a result the temperature of the gases exiting the flue of a condensing boiler is typically 50-60°C compared with 120-180°C in a current non-condensing boiler. At the same time an amount of water or 'condensate' is produced.
A condensing boiler will always have a better operating efficiency than a conventional non-condensing one due to its larger and more efficient heat exchanger.
Is your boiler energy efficient?
If it's 10-15 years old then it probably isn't. Replacing your old boiler with a new high efficiency condensing boiler can save you around a third on your heating bills straight away.
And that's not all... If you install the right heating controls, you could save up to 40% on your fuel bill - that's about £190 - £240 off the average bill.
OK, but how much does a new boiler cost?
Condensing boilers are available for both gas and oil fuel supplies, installation time can be from one to three days and cost from £900 upwards.
How will it help sell my house?
Each of my installations is followed up by certification from CORGE or OFTEC if it is oil installations, who in turn inform building control that the installation has been completed to a satisfactory standard. This information is required for the new home information packs (HIPS)
