The Energy Savings Trust has published new figures for expected savings from heat pumps.
The Right Honourable Clare Short visited Ice Energy Heat Pumps to learn more about heat pump technology and its role in tackling fuel poverty.

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.
