Heat pumps work by moving heat from one place to another. A ground source heat pump uses the sun’s heat by collecting it from the ground via a circulating loop of glycol. When the loop reaches the heat pump a refrigerant system extracts the heat energy which is then used for heating and hot water.
Ground source heat pumps can use heat from the ground with an average temperature of 10 degrees to heat hot water all year round. This works by the ground loop gathering a few units of energy per metre of the loop. As it uses a very large area in which the heat is constantly replenished by the sun, this then generates lots of units of energy in which it can then be utilised into a small area of your home.
The ground surrounding your property needs to be around 3 times larger than the floor area of your home for a horizontal loop . Borehole loops, which are vertical can also sometimes be a solution where space is of a premium.
For every unit of electricity, a heat pump will produce between 4 and 5 units of heat energy for your home. With a high proportion of heat from a heat pump coming from a sustainable environmental source, CO2 emissions are substantially lower than fossil fuel systems. This helps to reduce your carbon emissions and save the planet.
We have vast experience of designing and installing effective heat pump systems in various properties and can advise you on your options and which system is best suited for your needs.
