The New Year is traditionally seen as a time for change and in light of recent figures released by the Department for Energy and Climate Change (DECC), this may never have been more true if you are one of the million plus people using oil to heat your home.
The moment we have all been waiting for has finally arrived as the world's first Renewable Heat Incentive (RHI) launches to the Commercial sector.
Information published on the legislation.gov.uk website indicates that the rules governing permitted developments have been extended to cover the installation of Air Source Heat Pumps.
Claire Graham uses 2x17kW ground source heat pumps to heat her large detached home.

Ground loops consist of a series of pipes buried in the garden at a depth of 1 metre. The ground temperature at this depth is fairly constant between 7 and 13°C throughout the year. The heat pump uses a ground loop (pipe) with a water and glycol mix to "capture" some of this heat.
There are two main types, and the one to use depends on the amount of land available:
Straight ground loop;
Slinky ground loop;


Bore holes offer a solution where very little land is available. A vertical hole is drilled to a depth of 50 to 80 metres through the rock underneath the garden.

The option also exists to bury a pipe on the bottom of a lake or river and collect heat from the stream water.
