This more conventional form of renewable energy uses the heat from the sun’s solar radiation to supply a source of hot water and heating. Directly beneath the Earths surface, the ground maintains a relatively constant temperature of approximately 12 degrees, and during colder months, will be substantially warmer than the air & buildings above. By using a system of pipes buried in the ground, a mixture of refrigerant and water is used to absorb heat from the ground, before being concentrated and transferred to a building. This system can then provide a perfect low temperature heating system such as underfloor heating. The efficiency and size of the system will determine how much heat can be harvested. Longer ground loops will draw more heat, although if space is limited, a vertical borehole can be used in a similar manner.
