Ground Source Heat Pumps

Drawing as much as 75% of the energy needed by the heating system from freely available, inexhaustible solar energy stored in the ground, NOBO Eco-Series ground source heat pumps are available in an extensive range of models types and capacities suitable for either domestic or commercial applications.

Due to highly stable temperatures below the earth’s surface, ground source heat pumps provide high levels of efficiency for space and water heating all year round.

Heat from Your Garden

The earth stores an enormous amount of solar energy from both solar radiation and rainfall. To extract this energy, ground collectors consisting of flexible poly ethylene pipes are buried in the earth, either horizontally or vertically. A mixture of water and anti-freeze is then circulated through the pipe loops, attracting the heat energy and transferring it to the heat pump.

 

  

 

Horizontal ground collectors

If a large enough land area is available, horizontal ground collectors provide an effective method of extracting heat from the ground. The pipework is buried at a depth of approximately 1.25m and spaced 0.75m apart. The land area required is dependent on both the capacity of the heat pump and heat conductance of the soil type in which the pipes are buried. As a space saving alternative to horizontal collectors, slinkies - consisting of coiled pipes buried in a trench – can be used.

 

Vertical boreholes

If land space is limited the ground collectors can be installed vertically in a borehole, drilled up to 100m deep in the ground. Multiple boreholes are commonly used in large installations where very high levels of heat extraction are required.
