The ground itself is a very efficient source of energy for heat pump systems. Ground source heat pumps use the Earth’s natural solar collection and heat storage capabilities as an infinite heat source/heat sink.
At between 1.7m and 3m below the ground, the temperature changes from 17ºC in the summer to 10ºC in the winter.
Deeper down however, the temperature of the ground is a constant 10ºC all year round. It is these relatively constant, dependable temperatures that can be harnessed using ground source heat pumps. The constant ground temperatures allow the heat pump to operate at optimum efficiency, producing higher COP’s than its air source rivals as the high summer or low winter temperatures do not influence performance. Heat is extracted from the ground using water which is pumped through a network of plastic pipes.
