Ground Source Heat Pumps (GSHP)
Greenheat Renewables Ltd are experts in the installation of GSPH technologies with over 12 years’ experience. We have designed and installed heat pump solutions for all types and sizes of domestic and commercial properties from new builds to period and listed properties, and numerous industrial buildings.
No two projects are exactly the same, and each installation will start with a comprehensive assessment of the property including heat loss calculations.
We will meet with you to understand your project requirements, and work with you to build a bespoke solution for all your heating and hot water requirements.
How it works
Ground source heat pumps (GSHPs) use pipes buried in the ground to take solar energy stored underground to provide heating and hot water for your home. There are many benefits to GSHP, not least the efficiency - for every kWh of electricity used to run the heat pump extracts approximately 3 or 4 kWh of energy from the ground which is turned into heat.
A GSHP installation requires pipes to be installed in the earth to enable heat to be extracted from the ground – the type of ground collector installation (whether vertical or horizontal closed loop, or open loop / ground water) will depend on a number of factors including the physical space available. We can assist in findig the right solution for your project.
GSHP operate on the same principles as a domestic fridge, but use the cycle in reverse. A ground source heat pump circulates a mixture of water and antifreeze around a loop of pipe, called a ground loop, which is buried in your garden (or if space is limited, a vertical borehole can be drilled instead). Heat from the ground is absorbed into the water / anti-freeze mixture and then passes through a heat exchanger into the heat pump which then distributes the heat to the emitters. The ground stays at a fairly constant temperature under the surface, so the heat pump can be used throughout the year.
The GSHP can generate sufficient energy to heat your home and hot water.
There are a number potential benefits to installing a GSHP such as lower energy bills and carbon emissions (depending on the fuel type currently used), it could generate an income from the governments RHI scheme (see Grants) and generate heat for your home and water more efficiently than conventional heating systems.
A heat pump can reduce energy bills by 40-80% when compared to conventional oil or gas systems. The cost savings will depend on a number of factors including how well your home is currently insulated.

Things to Consider
There are a number of factors to consider in any GSHP project including:-
The size and type of the property - this will help determine the required size of pump
The current heating system and fuel type used - this will be factored into the potential costs savings a GSHP will provide
How well the property is currently insulated - a GSHP will work more efficiently in a well insulated draught free home
What type of installation (vertical borehole or loop ground collector) would be the best solution for your property / building - this may depend upon the space available
An ASHP requires electricity to operate. Adding Solar PV technology to the system can improve the efficient and increase cost savings.
We can help you assess whether GSHP is the best solution for your project and provide you with costings and estimated savings from the installation.
Grants and Subsidies
There are a number of different grants and financial incentives available from the Government to help with the cost of installing this technology.
The grants available will depend on where you are based (there are different schemes depending on whether you live in Scotland or the wider UK). There are also different schemes for domestic and commercial installations - See Grants.
How Greenheat can help
Greenheat Renewables can help you assess whether a GSHP is the best solution for your project.
We can provide you with more detailed information how the technology works and discuss the various options for ground collectors (including open and closed loop, horizonal and vertical boreholes).
Our design engineer can conduct an initial site visit (or can discuss your project over the phone) and provide you with a heat loss assessment and an indication of the size of pump and system you may need.
We can also provide you with estimated cost savings form the new system and potential income from the RHI scheme.
We have undertaken a huge variety of projects installing GSHP systems, both domestic and commercial and we thrive on finding solutions which are right for you.
If you would like more information on GSHP or would like to have a more detailed discussion about your project please contact us on (+44 (0) 1361 315000 or send us an e-mail to firstname.lastname@example.org. Our design engineer will be in touch to answer your query.
