The ground underneath your property acts like a solar heat battery, with an average temperature of around 12C. This temperature is high enough to heat a mixture of water and antifreeze running through a closed loop pipe system laid within the subsoil by Baystar approximately 1 meter deep. A heat exchanger uses this liquid to evaporate a more unstable, refrigerant liquid, similar to the one used in domestic and commercial fridges. The evaporated refrigerant is compressed inside the Heat Pump, raising its temperature much higher. A heat exchanger then ‘robs’ this higher heat, transferring it into your building’s internal network, powering radiators and underfloor heating systems, and delivering piping hot running water. Whether you have a horizontal or vertical ground source system put in place will depend on the space available around your property, but both are very similar in performance.
For both horizontal loop and borehole systems the size/length/depth of these is determined by the heat loss of the building area. Depths of boreholes range between 75m and 200m. The boreholes must be spaced accordingly to avoid any interference between the collectors, usually between 5-6meters minimum for boreholes. In each of these scenarios there will be considerable disturbance to the ground during these works however the ground will be reinstated and can be used as normal again once installed.
