How does it work?
The principles of a heat pump have been well known in physics for more than a hundred years and they are the same laws of nature that are used in a fridge or a freezer. There are three separate loops involved; collector loop, heat pump, and the central heating system and hot tap water.
A collector (or ground loop) collects the stored thermal energy from the ground and brings it into the heat pump. The layout of the collector loop can vary. If there is a generous amount of space outside the property, and the soil is relatively easy to dig, the best option is to dig a horizontal ground loop. If the space is limited or if the building is located on a rock, the best option is to drill a bore hole. If the property is located near a body of water, the thermal energy can be retrieved from there.

It collects the thermal energy and then transfers it to the refrigerant in the evaporator where the refrigerant boils and turns into a gas which then flows into the compressor. This is where the temperature and pressure is further increased. The hot gas is then transferred into the condenser where the heat is relocated into the central heating and hot water system. The gas decreases in temperature and condenses back into a liquid. Finally, the expansion valve reduces the pressure of the refrigerant, which also decreases its temperature and the process begins all over again.Collectors.htmlshapeimage_2_link_0
