Heat pumps extract the warmth from solar energy which is stored in the ground, water courses and in the air. The systems use electricity to drive a pump which extracts the warmth and upgrades it into useful heat. Fridges are heat pumps and work by the same principal but in reverse, moving heat from inside the fridge to outside, thus cooling the inside. There are 3 main options; Air Source Heat Pumps (ASHP), Ground Source Heat Pumps (GSHP) and Water Source Heat Pumps (WSHP).
Air Source Heat Pump
With air source heat pumps (ASHP) a fan draws air in to the unit and this flows over a closed loop of coiled piping circulating a fluid (either a mixture of water and anti-freeze or brine) which extracts the heat from the air. Air to water systems then use the heat to provide for central heating systems. Air to air systems mostly use fans to circulate heat into the property, but don’t produce hot water.
Ground Source Heat Pump
A ground source heat pump (GSHP) extracts heat from the ground by circulating a fluid (either a mixture of water and antifreeze or brine) through a closed loop of underground piping. This fluid absorbs the heat stored in the earth and carries it to the heat pump in the building.
Water Source Heat Pump
Water source heat pumps (WSHP) extract heat from a local water source and usually operate exactly like ground source heat pumps with a fluid pumped around a cyclical “closed” system. However, some systems are “open” and involve water being pumped out of the ground from a borehole and discharged via a heat exchanger to a river or sewer.
Combining Heat Pumps with Solar Energy
Heat pumps, being powered by electricity, are the perfect renewable energy partner for Solar Photovoltaic Panels (PV) as any free energy generated through solar power can be used to heat your home, so with careful use a heat pump and solar PV system in your home could mean an end to heating and electricity bills.
If you install an Air, Ground or Water Source Heat Pump between 20th May 2013 and March 2014, and have had a Green Deal Assessment carried out, you can get up to £2,300 towards the costs in the form of a voucher with the Renewable Heat Premium. (Smaller voucher amounts are available if the install was before 20th May 2013).
Plus look out for the Renewable Heat Incentive (RHI) in Spring 2014 when you can earn a fixed income for every kilowatt/hour of heat you produce from Ground Source Heat Pumps...
