Ground Source Heat Pump

What is a ground source heat pump?

A ground source heat pump extracts the heat from the ground source (which is vast reserve of free low grade heat which can be found just a few metres below the surface). Heat pumps can extract heat even during winter months when outside temperatures are low.

A heat exchanger within the heat pump will transfer the heat to the refrigerant which is then compressed to raise its temperature; a second heat exchanger called a condenser then takes out the heat from the refrigerant and transfers into the hot water for central heating, underfloor heating and domestic use.

A heat pumps efficiency is known as its COP (Coefficient of Performance). This is a simple ratio between the total energy produced and the amount of energy consumed to operate the heat pump. The higher the COP the more efficient the heat pump. Every 1 kW of electricity consumed by the Water-Water heat pump produces 4 – 6 kW heat energy for your home depending on the ground temperature.


Ground source heat pumps provide an ideal heating and hot water system for a wide range of applications from homes to swimming pools, and boats to businesses.

The infinite free warmth harnessed by a ground source heat pump means it is an ideal heating and hot water system for a wide range of applications.
