Energy efficiency

Boilers account for around 60% of the carbon dioxide emissions in a gas heated home. By fitting a new high efficiency condensing boiler and improving your heating controls, you will significantly cut your home's carbon dioxide emissions and could save as much as *£275 a year.

Condensing Boilers
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 DTW can tell you which type of condensing boiler, regular or combination, is most suitable for your home.

What is a high efficiency condensing boiler?
A high efficiency condensing boiler works on the principle of recovering as much as possible of the waste heat which is normally wasted 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.

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. 

Condensing boilers can be easily fitted to most new and old heating systems. Why don't you ask DTW for more details?
