Geothermal
Geothermal takes its energy from the ground and works on the basis that the underground temperature remains constant throughout the year as opposed to overground temperatures which can fluctuate greatly by season. Because of this Geothermal Pumps can generate heat very efficiently at a constant temperature which is most suited to underfloor heating systems.
Coupled with specific weather compensating controls and stats this system is ideal for most dwellings and has an overall payback period of between 10 – 15 years. There are two main types of collectors, horizontal collectors via pipe coils buried at specified intervals approximately 1m below ground level or vertical bored wells which range in depths of 100m to 150m. The former is least expensive in terms of installation costs whereas the latter is used where ground space is limited or specific soil conditions are unsuitable.
