Ground source heat pump (GSHP
) system for second floor heating and cooling.
The first barrier to wider application of quality GSHPs
is the high cost of the ground loop.
List the operation and maintenance advantages of GSHPs
arranged in cascade (total capacity of 120 kW/409,457 Btu/hr) provide warm water for TABS, for the heating coils in the variable air volume (VAV) system, and for floor heating.
Mr Brown added: "GSHPs
have the potential to make a difference to the Government's bold aims in the Clean Growth Strategy and, crucially, the wider environment and UK carbon footprint."
This low grade energy could potentially be extracted by nearby vertical ground heat exchangers (GHEs) or ground source heat pump (GSHP
While we recognize that the source energy for GSHP
systems in heating mode is stored solar energy in the earth's crust, we believe that the term geothermal is not necessarily incorrect.

Yet, as Dan Ellis cautioned, "Flow can you create a market for geothermal if there's nobody there to service the demand?" Ellis is CEO of Cl imateMas-ter, the largest and most well-known manufacturer of GSHPs
in the world.
use a fair amount of space - although you can get borehole systems which take up less - and you'll need to dig up at least a part of your garden to install one.
