What is a ground source heat pump?
A ground source heat pump extracts heat from the ground outside and transfers it to your home to heat your radiators or underfloor heating. It can also be used to heat water stored in a hot water cylinder.
It works by pumping a mixture of water and antifreeze, otherwise known as thermal transfer fluid (TTF), into the ground outside through the heat pump. This mixture is then continuously warmed by the constant temperature of the ground. The heat is absorbed into the liquid mixture and passes through a heat exchanger, which boils it to turn it into gas.
The gas is then fed into both a compressor and a condenser, where it can be distributed to the central heating system in the home or commercial building, providing heating and hot water where it's needed.
