Ground Source Heat Pumps

Enjoy constant heat and hot water without worrying about large energy bills. You can save money with a ground source heating system that uses a renewable energy source.

Using the Earth’s constant temperature as an energy source, building energy consumption and associated emissions can be reduced by more than 40% when compared with air source heat pumps and by over 70% when compared with electric resistance heating and standard air conditioning.

How do Ground Source Systems Work?

The earth is a huge solar collector, absorbing 47% of the sun’s energy, more than 500 times more energy than mankind needs, every year, in the form of clean renewable energy.

Using conventional heat pump technology and a ground loop heat exchanger, low grade heat is drawn from the earth and transferred to a fluid inside the ground loop, buried underground. The fluid then travels along the loop to the heat pump through a compressor where the temperature is raised to provide heating and hot water. For cooling the process is reversed with heat being rejected back into the earth.

A Renewable Energy Source

Ground source energy is a renewable resource. In the heating cycle, a ground source system will move at least 3 kW of energy from the ground for each 1 kW of electricity used by the heat pump. In the reverse cycle the same heat exchanger rejects excess heat to the earth at similar returns.

Benefits of Ground Source Heat Energy

  • Lowers your fuel bills and saves you money.
  • Uses renewable solar energy.
  • Reduces building energy consumption.
  • Reduces your home or business carbon emissions.
  • Reduces maintenance costs (ground loops require no maintenance).
  • Higher Coefficient of Performance (COP) than air source equipment due to the constant ground temperature.
  • No requirement for on-site fossil fuel consumption.
  • May provide income from the government backed RHI Scheme.
