Ground source heating & geothermal energy from Earthtest

Earthtest Energy's experienced team of Geologists and Mechanical Engineers provide comfortable warm homes using ground source heating, a sustainable and renewable energy source.

Ground source heating - The benefits

Escalating energy costs and the increasing concerns of global warming dictate that alternative sources of energy must be considered by individuals, businesses and the government. We are here to provide you with that alternative energy source, at the same time as saving you money!

At Earthtest Energy we harness geothermal energy by using ground source heating pumps, this is heat from the ground that occurs naturally, both from the sun and generated by forces within the earth to maintain a relatively constant temperature (usually 10°C to 12°C) at depths of more than 15 metres beneath the surface. Therefore, it is clean, green, environmentally friendly and sustainable. Plus, geothermal heat also has its advantages over shallow ground source heating, as this relies solely upon heat from the sun and is thus less efficient in winter.

To make use of geothermal energy we put in place ground source heat pumps that draw the heat from the ground in order to heat buildings. This means that these pumps use less energy than conventional heating systems - for every kilowatt of electrical energy three and a half to five kilowatts of heat energy are produced.

Geothermal heat can then be removed from the ground by various methods, such as abstraction of water - open loop - or from an antifreeze mix (brine) – closed loop - passed through pipes within boreholes that have been sunk in to the ground. The warmth from the ground is captured in the groundwater or brine and is extracted by the heat pumps.

We also use other methods to support this process in order to make each property as efficient as possible. Therefore, Whole house ventilation is used to manage the airflow in to and out of a building, ensuring a healthy odour-free environment. With our system of heat recovery you can reduce the heating requirement by a half.

In addition, correctly installed Underfloor Heating can effectively heat a building using water at 30°C, thus enabling heating systems to operate at peak efficiency. total solution, reducing heating costs and reducing carbon dioxide emissions.
