A renewable energy heating system is composed of several elements: a source of energy, equipment in the plant room and a method of distributing the heat within the building.
Ground Source Heat Pumps (GSHP) extract energy from the ground or from water. Air Source Heat Pumps (ASHP) take their energy from the air. The technology found in heat pumps is not new. The same basic principles are used in a fridge or freezer which means that heat pumps are reliable and have a long life. More...
Heat pumps run at their highest efficiency with lower heating system flow temperatures than traditional heating systems. The method of heat distribution used in a building is therefore important. Heat pumps run very effectively with under floor heating, which is a popular choice in new buildings but can be integrated with radiator or fan coil based distribution systems. More...
