A ground source heat pump draws heat from the earth and converts it into energy for heating and hot water through a system of pipes and heat exchanges.
Loops of pipe are installed underground, either along trenches or down a borehole. Through these pipes runs a liquid solution which absorbs the low-level heat from the surrounding earth and rock.
The warmed solution is transferred through a heat exchanger inside the pump into a refrigerant circuit, which when compressed, raises the temperature to a much higher level.
This usable heat is then transferred through another heat exchanger into the heating and/or hot water system of your home. The cooled liquid continues through the pump and back out into the pipe loops, ready to be warmed again, providing a constant flow of energy.
It’s an energy efficient, renewable source of heating for your home – which is a great choice if you’re not on the mains grid system and need to use alternative energy sources.
