Ground Source Heat Pump

What is a Ground Source Heat Pump?


A Ground Source Heat Pump takes the naturally occurring energy either in the ground or in the water. The energy is then passed either through a system of pipes or a heat exchanger to the heat pump.
heat pump then produces heating on one side and chilling on the other in two separate hydraulic circuits.
The Calibrate Heat/Chill H
eat Pump system then uses the heating to apply to the farmers’ agricultural process, whether it is grain drying, space heating, daffodil drying or any other type of agricultural product drying.
We also use the chill to chill products like potatoes, milk.
dehumidification or the cold fluid is sent to the ground or to the water to be heated naturally again.
This chill process is recovering the waste energy which increases the efficiency of the system by taking heat from the product and boosting the ground with that waste energy.
It is a combination of recovered energy and naturally occurring energy used to run the heat pump system.
Making the GSHP a high efficiency heating and cooling system.

What are the benefits of a GSHP?

Ground Source Heat Pumps not only save the environment, but they save money.

There are no fuel storage requirements for Ground Source Heat Pumps therefore, they save space.

Heat pumps don’t emit any potential dangerous gases therefore, are extremely safe.

GSHPs are the only kind of renewable energy technology that can benefit from the thermal energy storage properties of the ground arrays to recycle heat from summer to winter. They provide heating during winter but can also provide chilling during summer.

GSHPs are safe, silent, unobtrusive and out-of-sight: they require no planning permission.

Heat pumps can help to lower your carbon footprint as it uses a renewable, natural source of heat – the ground. Therefore, reduces the use of fossil fuels as these are not imported.



We can dry grain through this system by either pre-heating onto an existing flowdryer or heating onto a drying floor. We can also provide dehumidification in this process whereby we install a chill coil before the heating call which chills the air in order to dehumidify before heating again to be drawn over the product by the fan. 

Other heating applications include: 

  • Space Heating: a fan draws air over a warm radiator
  • Grass Drying
  • Product Drying. 
  • Underfloor heating in chicken sheds


We use the chill to: 

  • Dehumidify
  • Chill down the products including potatoes, swedes, milk and fruit; in doing this we recover the energy from the product and give the chill to the product.
    (Potatoes and swedes are chilled through air chilling and milk is chilled through fluid to fluid chilling through a plate exchanger).

Temperatures and Efficiencies 

  • The temperature range can go from 45 degrees down to -6 degrees.
  • Installation costs vary depending on the wattage size of the Ground Source Heat Pump
  • A GSHP minimises the use of fossil fuels, by using naturally occurring energy. Therefore, is very energy efficient creating energy savings and also benefitting from the Government’s RHI.
