Baxi Geoflo 4kW to 10kW

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

The heat pump consists of four main components:

. the compressor
. the expansion valve
. two heat exchangers (the evaporator and the condenser).

We also provide the matching ground array (slinkies) and manifolds to complete the package

The diagram shows how the from the ground is transferred to a usable heat within the system.

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.

Thanks to our continuing commitment to the environment, Baxi can now provide one of the largest ranges of heat pump systems on the market. There are seven single phase models available ranging from 4kW up to 20kW.  The 4kW - 10kW range is suitable for small to medium sized properties and the 12kW to 20kW range is suitable for medium to large sized properties.
