Condensing Boilers

From 2005 the Building Regulations require that in virtually all new domestic boiler installations which use Gas –condensing boilers will now be the only type permitted. This is in line with the government’s commitment to reduce the UK’s energy consumption and emissions of harmful green house gases such as carbon dioxide.

During the operation of condensing boilers, exhaust gases are expelled out of the flue; a condensing boiler is able to extract and use much of the heat from the gases before the flue gases discharge. This ability to extract more heat from the fuel it consumes makes it more efficient and also reduces emissions.

Around one quarter of Britain’s carbon monoxide emissions originate every year from the energy we use to heat and light our homes.

It’s because we burn fossil fuels (gas) to produce that energy. And over time the resulting waste gases do add to the effect of global warming. To a degree just changing an older style boiler to a new conventional or combination boiler (around 80% efficient) is a big step in the right direction, any boiler over 15 years old is inefficient (approximately 50% efficient), wasting natural resources and your money.

If you’d like to really reduce emissions and your gas bill then installing new ‘High Efficiency Condensing Boilers‘ (around 91% efficient) would be the best way forward. Yes, it is a little more expensive initially, but you’ll gain in the long term when you notice that your fuel bill has been reduced substantially. In some homes more than one third.

But it has to be mentioned, condensing boilers need to have a lot of thought when it comes to the position of the boiler and the flue, this is because there is a large amount of ‘Pluming’ (steam / water vapour) which comes out of the flue outside. Consideration needs to be taken regarding neighbouring properties and boundary lines.

Condensing boilers mean high efficiency. The type of system you have installed will be either a ‘Conventional System’ (see our page on conventional boilers) or a ‘Combination System’ (see our page on combination boilers).

We can survey your property and help you to decide the right type of system for your property and the best place for us to install your condensing boiler.
