Ground Source Heat Pump
Overview
Ground source heat pumps extract renewable heat stored naturally in the ground and use it to efficiently provide space heating and hot water. The recovered energy is distributed through radiators, underfloor heating systems and hot water cylinders, delivering a highly efficient, low-carbon alternative to conventional heating systems.
Ground source heat pumps are particularly well suited to properties with sufficient outdoor space, as they require ground loops to collect heat from the earth. They are an excellent option for new-build projects, self-builds and retrofit installations, especially in well-insulated homes and buildings where maximum efficiency can be achieved. Although installation is more involved than air source heat pumps, the system benefits from stable ground temperatures, resulting in consistent performance, lower running costs and minimal ongoing maintenance.
Greenio installs only proven, high-quality ground source heat pump systems, supported by strong manufacturer warranties. Combined with our expert system design, professional installation and commissioning, this ensures reliable performance, long-term efficiency and confidence throughout the system’s lifespan.
How Do GSHPs Work?
A ground source heat pump system is connected to a network of underground pipes known as ground collectors, ground loops or ground arrays. These pipes are installed either horizontally in trenches or vertically in boreholes, depending on the available space and ground conditions.
A mixture of water and antifreeze circulates through the ground loops, absorbing renewable heat stored naturally in the earth. This low-grade heat is then transferred to the heat pump, where an electrically driven compressor raises the temperature to a usable level.
The captured heat is passed through a heat exchanger and distributed throughout the property to provide space heating and hot water, supplying radiators, underfloor heating systems and hot water cylinders efficiently and reliably.
Benefits of a GSHP
Environmentally friendly
Ground source heat pumps are a clean, low-carbon heating solution. They are combustion-free, producing no on-site emissions and removing the need for fossil fuels such as gas or oil.
​
Exceptional efficiency
GSHPs are among the most efficient heating systems available. They can achieve efficiencies of up to 400%, meaning for every 1kW of electricity used, up to 4kW of heat energy can be delivered. This significantly reduces overall energy consumption.
​
Reduced carbon footprint
By harnessing renewable heat stored in the ground and using only a small amount of electricity to operate, GSHPs greatly reduce carbon emissions compared with traditional heating systems.
​
Potentially carbon free operation
When powered by renewable electricity sources such as solar PV or wind, a ground source heat pump system can operate with near-zero carbon emissions, supporting long-term sustainability and net-zero goals.
​
Heating and cooling capability
In addition to providing space heating and hot water, GSHPs can also deliver passive and active cooling. This removes the need for a separate air conditioning system, saving space, installation time and overall cost.
​
Long lifespan and reliability
Ground source heat pumps are built for long-term performance. The heat pump unit itself typically has a lifespan of 25–30 years, while the underground ground collectors can last 100 years or more, making GSHPs a highly durable and future-proof investment.
Ground Source Heat Pump – Frequently Asked Questions
Will a ground source heat pump work with my existing radiators?
Yes. Ground source heat pumps can often be connected to existing radiators, underfloor heating systems and hot water cylinders. During our site survey, Greenio will assess your current heating system to confirm compatibility and advise if any upgrades are required to ensure efficient operation.
​
Are ground source heat pumps noisy?
No. Ground source heat pump systems operate very quietly. The majority of the system is installed underground, and the internal heat pump unit produces minimal noise. GSHPs fall within permitted development requirements and are designed to operate without causing disturbance.
​
Is a ground source heat pump difficult to maintain?
No. Ground source heat pumps require very little maintenance. There are no combustion-related safety checks, and routine servicing is straightforward.
The heat pump unit itself typically lasts 20 years or more, while the underground ground loop can last 50 years or longer, making GSHPs a reliable long-term solution.
​
Is my property suitable for a ground source heat pump?
Suitability depends on factors such as your existing heating system, energy demand and the amount of available outdoor space. Properties with sufficient land for ground loops or boreholes are generally best suited to GSHP installations. Greenio will assess feasibility as part of a detailed site survey.
​
What additional benefits come with installing a GSHP?
With a ground source heat pump, there is no need for:
-
A flue
-
An oil tank
-
A gas connection or fuel storage
This improves safety, frees up space and removes the need to pay in advance for fuel deliveries, while providing a stable and efficient heating solution.
