Ground Source Heat Pump
Based on refrigeration technology heat pumps are extremely reliable with no regular maintenance required, they have a planned life span of 25 years with no loss of efficiency. So how do they work and how can they be applied. The earth, water and air absorb and store heat from the sun. In the UK the average constant temperature of the earth at about 1.5M deep is around 5-12°C. It is also possible to extract usable heat from ambient air temperatures as low as -15°C.
