Ground source heat pumps – Geothermal

Citigas are experienced domestic and commercial Renewables engineers. Citigas can install an ground, or air, source heat pump at your home and commercial premises.

Ground source heat pumps extract geothermal energy from the earth.

A ground source heat pump uses a system of pipes buried in your garden or outside space to extract heat from the ground. This heat can then be used to heat radiators, underfloor or warm air heating systems and hot water in your home.

A ground source heat pump circulates a mixture of water and antifreeze around a loop of pipe – called a ground loop – which is buried in your garden. Heat from the ground is absorbed into the fluid and then passes through a heat exchanger into the heat pump. The ground stays at a fairly constant temperature under the surface, so the heat pump can be used throughout the year – even in the middle of winter.

The length of the ground loop depends on the size of your home and the amount of heat you need. Longer loops can draw more heat from the ground, but need more space to be buried in.  If space is limited, a vertical borehole can be drilled instead.

In our view those customers have a large area of land where the pipework loops can be installed will benefit the most from this type of technology.
