How does the Geoflo ground source heat pump work?
The Baxi Geoflo ground source heat pump system taps into the natural heat found in the ground just metres below the Earth's surface. The heat pump works by keeping fluid in the evaporator slightly cooler than the source, enabling it to draw latent heat from the earth via heat collectors which are buried in the ground.
This stable, consistent energy is used to provide hot water for a domestic heating system.
The heat pump collects the heat at around 10oC and increases the temperature to a level suitable for a heating system. The more the heat pump raises the temperature, the less efficient it is, which is why this system is more suited to underfloor heating systems at around 35oC
Highly energy efficient
For every 1kW of energy used 4kW is transferred into an underfloor heating system (COP4:1). This can provide substantial carbon reductions per annum.
