A recent study by the Energy Saving Trust of Northern Ireland on domestic heat pump systems indicates that the highest energy efficiencies were achieved by the most basic home heating systems.
Heat pumps offer home owners a method of obtaining hot water and heating their house by taking advantage of the heat trapped just below the ground in their gardens and lawns. In the ground source system, the heat pump circulates a refrigerant which collects the heat trapped in the ground around the house and delivers it into the house. During the winter, the soil under gardens is at a higher temperature than the air above it and the ground source heat pump system uses this situation to move heat around to the place it is wanted, in exactly the same way as a kitchen fridge operates, but on a larger scale.
