Government Changes

From April 2005 the goverment has insisted that all new central heating boilers must be highly efficient 'Condensing Boilers' which are able to recover heat, which, in the past, has been typically wasted by older more inefficient boilers.

Boilers are rated by SEDBUK standards for 'seasonal efficiency' of domestic boilers in the uk, you can check your own boiler, or the one you may be considering buying.

The central heating boilers we fit are 'A' rated highly efficient, and can reduce your fuel bills by up to 30%

Is a Condensing Boiler greener than a non-condensing one?

A condensing boiler makes better use of the heat it generates from burning fuels such as gas or oil. In a conventional boiler some of the heat is wasted because the boiler releases very hot waste gases from its flue.

A Condensing boiler uses some of the heat from these waste gases to heat water returning from your central heating system, so it requires less heat from the burner. This makes your condensing boiler more efficient.

The efficiency of a boiler is normally expressed as a percentage, some new condensing boilers can be up to 92% efficient compared to new non-condensing ones that are around 78% efficient and older boilers that are only 55 to 65% efficient.

How does a condensing boiler reduce carbon dioxide emmissions?

Carbon dioxide savings come from burning less fuel to meet your heating needs.

Imagine that one unit of fuel potentially contains enough energy to heat your home for an hour. Burning that fuel in a boiler that is 100% efficient would heat your home for an hour.

Burning that fuel in a boiler that is 90% efficient would only give you enough to heat your home for 54 minutes, and if it's 60% efficient you would only get 34 minutes per unit.

So, the lower the efficiency of your boiler, the more units of fuel you need to burn to keep your home at the right temperature.

The more fuel you burn, the more carbon dioxide you emit.
