Far from boring
Boreholes are the collectors used to extract heat energy from rock for ground source heat pumps. They are a very discreet and compact solution when space saving and minimal ground disruption is a priority, and ideal for heat network or district heating schemes.
Typically just one borehole is required per dwelling depending on the underlying ground conditions. Boreholes are the most expensive collector but become especially economically viable on large commercial projects, those with district heating or heat network schemes, and sites with heat loads above 100kW due to the costs involved of assembling the drilling rig and its speed when on site.Read more
