GROUND SOURCE HEAT PUMPS

Heat pumps work on a very similar principle to the common refrigerator in that they pump heat from one location and into another. At about one metre beneath our feet, the earth maintains a constant temperature of around 10-12 Celsius. This is because heat from the summer sun is stored in the ground and gently released back to the environment during colder periods.

Heat pumps tap into this energy, transferring the solar energy stored in the ground to provide heating and hot water for the home, in much the same way as your refrigerator transfers heat from inside the fridge and into the room. At the end of the heating season, the sun allows the temperature of the ground to recover again.
