Norfolk County Council has recently set up an energy company to take advantage of new government incentives (including the renewable heat incentive). Because of this and the fact that Norfolk is a rural county with a lot of space we are likely to be seeing the installation of many more heat pumps.
There are two main types of heat pumps air source and ground source, in this post I shall be talking about ground source. Ground source heat pumps, as the name suggests, take heat from underground and use it to warm a building, basically using the earth as a heat reservoir. The temperature under the upper 6 meters of the earth’s surface is generally between 10 and 16 °C (depending on latitude). The heat pump does not disturb this, it just harness the heat. This heat actually comes from the sun and gets stored in the ground.
Ground source heat pumps can also be used for cooling in the summer by transferring heat back into the ground. Heat pumps will automatically adjust whether they heat or cool adjusting depending on the outside temperature. Heat pumps are much more energy efficient than electrical heaters, and it is a smart move to have more ground source heat pumps in Norfolk.
