Heat PumpsHeat pumps are an efficient way to heat buildings, and are widely used in Scandinavia. They work by moving heat from one place to another, working on the same principle as a fridge. A heat pump moves heat from a natural heat source, such as the ground, or a well, to the inside of a building. Even at low temperatures, air, ground and water can contain useful heat, and heat pumps are about three times more efficient than electric storage heaters. For every one unit of electrical energy used, three to four units of heat are obtained. A heat pump can also easily be be reversed to provide cooling during summer. Ground source heat pumps require coils to laid under the ground. Water source heat pumps require a pond, well or stream. Further Information |
