What are Ground Source Heat Pumps?
Ground source heat pumps collect energy stored in the earth and use it to heat water in a cylinder for distribution to taps, appliances and radiators. This is one of the most advanced technologies available for home heating and hot water. Because the earth ‘stores’ low temperature heat energy it is an extremely reliable and constant energy source, it creates no harmful emissions and uses a very small amount of electricity.
Geothermal or ground source heat pumps have been around for many years in various forms but many people in the UK are still not aware of them or would consider them a viable option for heating their homes when considering a new heating system. Ground source heat pumps began to grow in popularity in Sweden in the 1970’s and today their popularity is still increasing all over the Western world. It is estimated that around 80,000 ground source heat pumps are installed in homes in the USA each year and around 27,000 in Sweden each year alone. These are becoming increasingly more popular in the UK and here at BES we are striving to promote this form of heating.
Why Heat Pumps?
Heat pumps use free energy from ground, air or water outside to produce space heating and hot tap water. Correctly designed and for the right kind of property, heat pumps can deliver both energy savings and carbon reduction. Correctly sized, heat pumps can produce all required heating and hot water.
The “right kind of property” for a heat pump is a well insulated property outside of the gas grid with a heating distribution system able to operate at relatively low temperatures (typically under floor heating or over sized radiators).
