Ground Source Heatpumps use the natural energy stored in the earth to heat your home. This is achieved through the system having a water based plate exchanger on the cold side of the system that pumps the water into the earth through closed loop pipes at a specific depth to maintain 7-10c. Alternatively we can utilise boreholes or natural springs and underground aquifers. 
Ground Source Heatpumps behave in a similar way to Air Source Heatpumps efficiency wise (COP of 3.2 - 5.2) albeit over the whole year Ground Source Heatpumps are more efficient as the winter temperatures don’t vary as much under the ground.  
All Ground Source Heatpumps that CALIBRATE ENERGY install qualify for the Commercial 20year Governemnt RHI tarrif and with savings of over 60% per annum on your commercial heating they are a viable, easy alternative to fossil fuel heating. On top of this most systems qualify for the green deal or carbon trust loan making it easy to finance the systems for your business.
