Condensing Boilers

Condensing boilers are the most efficient available as they convert over 90% of the fuel they use into useful heat, compared to around 60% for an old conventional boiler. If everyone in the UK who could, installed a condensing boiler, CO 2 emissions would be cut by more than 12 million tonnes and the energy saved would be more than enough to heat every household in Scotland for a year.

Is your boiler energy efficient?

If it’s 10-15 years old then it probably isn’t. Replacing your old boiler with a new condensing boiler can save you around a third on your heating bills straight away.

Around 60% of CO 2 emissions from your home are down to your boiler. With an efficient new boiler you could save up to 875kg of CO 2 and £170 a year.

Add in a full set of heating controls as well as a new boiler, and you could increase the total savings to around £275 and 1.4 tonnes of CO 2 a year.

Save a third on your heating bills by replacing your boiler

Condensing boilers can be easily fitted to most new and old heating systems, ask us for more details.

Did you know?

If everyone in the UK with gas central heating installed a high efficiency condensing boiler, we would save enough energy to heat 3.4 million homes for a whole year and save around 12 million tonnes of CO 2.

What is a high efficiency condensing boiler?

Condensing boilers get their name because they condense periodically. In other words, they extract heat from the exhaust gases that would otherwise escape through the flue - turning water vapour from the gas back into liquid water or condensate.

A condensing boiler captures much more usable heat from its fuel than a non-condensing boiler. Its high operating efficiency is made possible by the design of the condensing boiler’s larger - or sometimes dual - heat exchanger.

The heat exchanger makes sure that as much heat as possible is transferred from the boiler’s burner - and as little as possible lost in gases through the flue.

There are two types of condensing boiler: regular and combination. Regular condensing boilers heat your hot water through a hot water cylinder. Combination condensing boilers give you instant hot water without the need for a cylinder.

Please bear in mind that not all home heating systems will be compatible with a combination boiler. We at Gas Trading will tell you which type of condensing boiler, regular or combination, is most suitable for your home. The costs and paybacks shown are approximate and are provided for illustrative purposes only and are based on a gas heated semi-detached house with 3 bedrooms. Savings assume a gas price of 4.03p/kWh.
