£320 K energy saving trial sees bills halved for participants

11th May 2012

An experiment in green living conducted in Cambridgeshire has seen energy bills halved for those taking part, partly due to the installation of a new boiler.

The residents of Rampton Drift in Longstanton have benefitted from a host of energy saving measures installed as part of an ongoing government scheme to include the settlement into a new town called Northstowe. The houses involved were all built between 1956 and 1970, so their central heating systems most definitely need updating. Other houses have also benefitted from solar panels and new insulation.

Wilmott Dixon have teamed up with South Cambridgeshire District Council to retrofit the homes which will be opened to the public for inspection this week. The houses are all ex-MoD stock and some of them have been fitted with high efficiency combi-boilers equipped with flue-gas heat recovery. There are also heat recovery extractor fans fitted in the bathrooms and kitchens.

The combi-boilers supplied are Alpha-CDC combi boilers with Gas Saver top boxes. This boiler has a built-in seasonality valve which automatically adjusts the hot water flow based on the temperature of water from the incoming main thereby allowing more flow in spring, summer and autumn.  The boiler is also fitted with Alpha Hydroblock which reduces the amount of pipework in order to save space and make servicing much easier. All the boilers have LED fault indicators and easy to use control panels. They also have easy to remove components which also helps with servicing.

Alpha’s high efficiency boilers are SEDBUK A rated, which is the highest possible SEDBUK rating. They operate at 90% efficiency which helps to save household energy bills as well as cutting carbon emissions.The boilers come with a 3 year warranty and are available with three flow rates ranging from between £757 to nearly £900.

Alpha are highly regarded as one of the best manufacturers of combi-boilers alongside Vaillant.
