FACT SHEET:  RENEWABLE HEAT TECHNOLOGY

HEAT PUMPS (AIR AND GROUND)

Heat pumps work like fridges in reverse. They extract warmth from the air or ground which is used to heat the home. The system is made up of liquid-filled pipes which absorb the heat from the air or ground, the liquid is then passed through a heat exchanger which warms the air or hot water supply. The cooler fluid is then re-circulated.

Air source heat pumps (ASHPs) are usually mounted on the outside of a building and domestic models are around the same size as air conditioners.

Ground source heat pumps (GSHP) extract heat from the ground from a series of pipes buried in the soil either in a horizontal network or in deep vertical holes.

SOLAR THERMAL

Solar thermal technologies are usually roof-mounted panels, which contain a network of liquid-filled tubes that are heated by the sun. The liquid can then be used directly to provide hot water within a building, or an exchanger can transfer the heat from the liquid to the building’s hot water system.
 
BIOMASS BOILERS

Biomass boilers generate heat through burning organic matter such as wood. The heat can either be used directly for heating, or to produce hot water. Most domestic installations would run on wood logs or pellets and have a storage area or a container, known as a ‘hopper’, located next to the boiler. Pellets can be manufactured from wood, sawdust, straw and crops specifically grown for energy purposes, such as willow and elephant grass and are designed for use with hoppers which automatically feed the boiler as more fuel is needed.
