Functioning principle of the pump to heat
Geothermal - how does it work? Can you get 65 degrees?
Geothermal Energy (GEO) is relatively new to the UK. In Switzerland (GEO) over 50 years, been installed in 1:8 houses, with 1:3 new houses, and a far harsher climate than the UK. The Swiss recognised that Energy from the earth was sustainable and over the last few years economic and secure. Low maintenance and reliability means the Swiss do not have any need for back – up systems.
The Ground Source Heat Pump (GSHP) acts exactly like your fridge, but in reverse – a combination of evaporator; compressor(s); condenser and expansion valve. The working fluid changes from liquid to gas (evaporates) as heat is absorbed from the heat source. Later in the cycle, the working fluid condenses to liquid as heat is released to where it is needed - modern turbo pumps deliver up to 65 degrees, topping up the buffer tank. The buffer tank – a Swiss feature - retains water with almost 100% efficiencies – permanently topped up from the “free” GSHP.
These super turbo pumps are excellent for older properties with older radiators. Because of the buffer tank the continual use of the pump, allows a average coefficient of 4 - or 4Kw of free energy for every 1Kw of electricity used.
