Offices And Commercial Buildings Use Geothermal Energy

 

For applications in the commercial sector, large borehole heat exchanger (BHE) fields or ground- water wells are the preferred groundside alterna- tive. While BHE are feasible virtually everywhere, and promise maintenance-free operation, their individual capacity is limited, resulting in huge BHE fields for systems with high heating/cooling demand (see table below).

Residential houses

For small houses, 1-2 borehole heat exchangers or a horizontal collector. A larger house may need more, but they are space close together. The installation is not visible from outside, the heat pumps (incl. buffer tanks and/or DHW tank, where appropriate) do not need much space, and a fuel oil tank or connection to the gas grid is not required.
