Below is a really good video to explain the principles of a ground source heat pump operation. It is a manufacturer produced video and so features their product.

Ground Source Heat Pump Library

Why not check out our library, over the years we have collected a great collection of technical documents from a number of manufacturers.

In simple terms a ground source heat pump works by circulating fluid through buried pipes in horizontal trenches or vertical boreholes, this passes through one side of a heat exchanger with a  liquid refrigerant the other side. As the refrigerant warms, it expands into a gas; just as the water in your kettle expands in to a gas (steam) when you heat it. This is evaporation and it requires energy.

You can prove the principle to yourself by gently blowing across the back of your hand, it feels warm. Now wet you hand and gently blow across it again, this time it feels cooler, that is because the water is taking the heat energy out of your breath to enable it to evaporate.

As the refrigerant evaporates into a gas, it stores the heat energy it has used to change from a liquid to a gas. By compressing the refrigerant gas it can be changed back into a liquid and it releases the heat energy.

Now what is really great, is that the energy required to compress the refrigerant gas back into a liquid, is a lot less that the energy the refrigerant collects from the air changing from a liquid into a gas. So by running a refrigerant cycle we can collect ‘free’ energy from the ground or even lakes, ponds and rivers.

A typical heat pump will deliver three to four times as much energy out compared with the energy put in to drive the compressor.

A well designed GSHP system provides the lowest running cost of any heating system – because it uses a small amount of electricity to transfer a large amount of naturally occurring heat from the ground into your building.  Ground source heat pumps generally do not require any planning consent to install.

Last night’s BBC Panorama focused on what ordinary people had to do to reduce their carbon footprint, looking at food, transport and energy, including Ground Source Heat Pumps. @vaillantuk
