Ground-Source Heat Pumps

You can now take advantage of free heat stored in the ground by using a ground-source heat pump! Solar energy stored in the ground can be collected through pipework buried in your land and used to heat your home or business.

Although this may sound too good to be true, ground-source heat pumps have been in use in other parts of Europe for many decades, so the technology is tried and tested and a highly efficient way to provide you with heat.

How do ground-source heat pumps work?

The principle of a ground-source heat pump is simple and the same as a standard domestic fridge. A fluid is pumped through a series of pipes which extracts heat from its surroundings (like the internal space of a fridge, or in the case of a heat pump, the ground in which the pipes are laid). Rather than losing this useful heat (as is the case at the back of a fridge), a heat pump compresses the fluid to raise the fluid's temperature, then passes it through a heat exchanger, to transfer the heat to a water supply (usually around 35-40 degrees but can be up to 65 degrees), which is then circulated around a central heating system.

Surprisingly, solar energy which is absorbed by the ground remains at a fairly constant temperature throughout the year so heat pumps can utilise this energy during the winter months when it is needed.

Although energy from the ground is free, there is a running cost involved in pumping the fluid around the system. Typically ground-source heat pumps can produce 2.5-4kW of heat energy for each 1kW of electrical energy used to run the heat pump. Heat pumps are virtually maintenance free and produce no emissions on site* as there is no combustion of fuel involved in the running of a heat pump system.

* Note that the electricity used to run the heat pump is likely to be generated using some fossil fuels, so some carbon emissions at the power station should be considered. However, these CO2 emissions are typically around 37% less than gas and 55% less than oil.

Are ground-source heat pumps suitable for my property?

There are two main issues to investigate when considering installing a heat pump:


A heat pump with hot-water buffer tank

 


Two NIBE heat pumps connected in series
