Heat Pumps use conventional refrigeration technology to extract and harness the sun's energy stored in the environment, and raise it to a temperature suitable for heating purposes.
Heat Pumps are among the most efficient heating and hot water systems available today. In the region of 75% of the energy needed for heating comes from the environment, and so for every 1kWh of electricity used to power the heat pump compressor, between 3 and 4kWh of heating energy is produced, providing an efficiency of 300-400%.
This efficiency is known as the Coefficient of Performance, or COP, and you may occasionally see reference to the Seasonal performance which takes into the difference in temperatures throughout the seasons.
Heat pumps can be used with the more traditional radiator systems, if the appropriate allowance are made, however they will work most efficiently with low temperature sources of heating such as underfloor heating, as the lower the flow temperature of the circulating water the higher the efficiency of the heat pump.
Before installing a heat pump it is essential to ensure that an accurate heat loss calculation has been carried out, consideration has been given to insulation levels, are there secondary heat sources, is hot water required, if radiators are being used have they been sized in line with a lower flow temperature.
In order to benefit from any grants of funding, and renewable heating incentives (when they are confirmed by DECC) you will need to have your heat pump system installed by a contractor approved by the Microgeneration Certification Scheme.
