Ground source heat pump installation by Greenstone
If you need advice or would like to discuss your energy needs give us a call and we’ll help you choose the right system for your home or business.
Our Ground Source Heat Pump Solutions
Here at Greenstone we pride ourselves researching the market and exploring which manufactures and model are best suited for specific applications. Heat pumps in general will save you more money in running cost and reduce more carbon emissions if the flow temperature to your radiators or underfloor heating is kept low.
We have attended many heat pump manufacture training courses and our current preference for ground source is NIBE.
What are the benefits of an ground source heat pump?
- Can be used for both heating and hot water production
- Provides good levels of efficiency all year round
- Lasts three times as long as a conventional boiler
- Designed to be low maintenance
- Nothing visible from the outside of the property
How does a ground source heat pump work?
How ground source heat pumps work
Heat pumps are a source of renewable energy as they take a low grade heat from the ground and transfer it into a high grade heat.
Ground source heat pumps extract energy from the ground which on average is about 10°C. Extracting this low grade heat at this temperature is still enough for the heat pump to multiple or amplify this heat to 65°C. Therefore, satisfying your heating and hot water demands.
Location
The heat pump unit is positioned inside your home, garage, utility or kitchen and the ground loop pipes are then piped through into the ground outside to extract the renewable energy.
History
The first heat pump created was in 1856 by Peter von Rittinger who used the heat pump to dry salt in salt marshes in Austria. As any product since its conception, there have been many improvements and applications for heat pumps. The UK is relatively new to this type of heating compared to Scandinavian countries where they have been using this technology for over 40 years. Due to the lack of fossil fuels these counties had to be proactive if their choice of heating systems.
Ground loops (pipes which extract the energy)
There are a few options on how we can install ground loops and it can depend on the surface area required and space available. Capital costs are also a key decision maker.
Horizontal Group Loop
Is the most affordable way to extract energy from your garden / field. It requires a 1 metre deep trench and 1 metre wide. The number of these trenches and length will depend on the energy demand from your property for heating and hot water. The pipes are laid down separated by 1 metre from each other.
Slinky Group Loop
Is the most affordable way to extract energy from your garden / field. It requires a 1 metre deep trench and 1 metre wide. The number of these trenches and length will depend on the energy demand from your property for heating and hot water. The pipes are laid down separated by 1 metre from each other.
Bore Hole (Closed loop)
Is the most affordable way to extract energy from your garden / field. It requires a 1 metre deep trench and 1 metre wide. The number of these trenches and length will depend on the energy demand from your property for heating and hot water. The pipes are laid down separated by 1 metre from each other.
Bore Hole (Open Loop)
Is the most affordable way to extract energy from your garden / field. It requires a 1 metre deep trench and 1 metre wide. The number of these trenches and length will depend on the energy demand from your property for heating and hot water. The pipes are laid down separated by 1 metre from each other.

MCS Certification
We are MCS certified:
“MCS is a mark of quality and demonstrates compliance to industry standards that companies strive to meet. It highlights to consumers that companies are able to consistently install or manufacture to the highest quality every time.”
More information on MCS can be found here www.microgenerationcertification.org.
Since it’s classed as a renewable technology it will qualify you to receive the renewable heat incentive. The renewable heat incentive together with the savings you make against your old heating system is designed to pay off the capital cost of the installation and equipment.
For domestic installations the payment from Ofgem directly to you last 7 years. More information from Ofgem can be found here.
For commercial installations the payment from Ofgem directly to you last 20 years More information from Ofgem can be found here.
