Energy-Efficient Ground Source Heat Pumps
Are you considering a more cost-effective and efficient way to heat your home in Suffolk? Ground source heat pumps (GSHPs) offer a sustainable alternative to traditional heating systems by harnessing geothermal energy. These systems provide reliable heating and hot water, while reducing your energy bills and environmental impact.
How Do Ground Source Heat Pumps Work
Ground source heat pumps use the consistent temperature of the earth to generate heat. They transfer energy from the ground into your home through two main setups:
- Open-Loop Systems: These use groundwater as a direct source of heat.
- Closed-Loop Systems: Fluid circulates through pipes buried in the ground to collect heat.
Closed-loop systems come in two configurations:
- Horizontal Systems: Pipes laid in shallow trenches, suitable for larger properties.
- Vertical Systems: Pipes installed in deep boreholes, ideal for smaller plots.
This process provides efficient heating regardless of external temperatures, making ground source heat pumps an excellent option for Suffolk’s variable climate.
Why Choose Ground Source Heat Pumps?
Switching to a ground source heat pump offers numerous benefits:
- High Efficiency: Achieve over 400% efficiency, with one unit of electricity generating around four units of heat.
- Lower Running Costs: Reduce your energy bills while minimising your reliance on fossil fuels.
- Performance in Cold Weather: GSHPs function effectively even at temperatures as low as -20°C.
- Heating and Cooling: Many systems can also cool your home, offering year-round comfort.
- Minimal Maintenance: Annual service checks are all that’s needed, with no fuel deliveries required.
GSHPs vs. Air Source Heat Pumps (ASHPs)
Both GSHPs and ASHPs are renewable heating systems, but they differ in how they source energy:
- GSHPs: Use stable ground temperatures for consistent heating. This stability ensures predictable energy costs and reliable performance.
- ASHPs: Extract heat from the air, which can lead to reduced efficiency during colder months.
While both options are sustainable, GSHPs offer a more dependable solution for long-term savings.
Comparison of Heating Bills and Savings with a Ground Source Heat Pump
Although there is an upfront cost of installing a ground source heat pump, it offers long-term savings on running costs that can make it a worthwhile long term investment. On average, a household could save between £500 to £1,400 annually on heating bills, depending on the size of the property and its existing heating system. These savings are particularly noticeable when replacing oil or electric heating systems, which are often more expensive to run.
You may also qualify for grants or incentives, such as the government’s Boiler Upgrade Scheme, which provides up to £6,000 toward installation costs. This support can significantly reduce the initial expense.
Studies have shown that ground source heat pumps have been found to increase your property’s value by in some cases more than 3% due to their energy-efficient and environmentally friendly credentials
Cost and Savings
Below is an estimated comparison of heating bills for different property sizes when using traditional heating systems (such as oil or electric) versus a ground source heat pump. These figures are based on average energy costs, and the efficiency of ground source heat pumps, which can achieve over 400% efficiency.
| House Size | Traditional Heating Bills (Annual) | GSHP Heating Bills (Annual) | Estimated Savings (Annual) |
|---|---|---|---|
| Small (1-2 Bedroom) | £1,200 | £700 | £500 |
| Medium (3-4 Bedroom) | £2,000 | £1,200 | £800 |
| Large (5+ Bedroom) | £3,500 | £2,100 | £1,400 |
Geothermal Heating for Sustainable Living
Geothermal heat pumps play a key role in promoting sustainable heating solutions. By relying on renewable energy, you reduce your carbon footprint and contribute to Suffolk’s efforts to combat climate change.
Below you can see an estimated annual carbon emissions (in kilograms of CO₂) for heating different properties using traditional systems (oil or gas boilers) versus geothermal (ground source) heat pumps.
The figures are based on average energy consumption and emission factors for the UK.
| House Size | Traditional Heating Emissions (kg CO₂/year) | Geothermal Heat Pump Emissions (kg CO₂/year) | Carbon Savings (kg CO₂/year) |
|---|---|---|---|
| Small (1-2 Bedroom) | 3,500 | 700 | 2,800 |
| Medium (3-4 Bedroom) | 6,000 | 1,200 | 4,800 |
| Large (5+ Bedroom) | 10,000 | 2,500 | 7,500 |

Frequently Asked Questions
Installation costs typically range from £13,000 to £20,000, depending on factors like property size and ground conditions. The UK government offers grants up to £7,500 through the Boiler Upgrade Scheme to help offset these costs.
Clima-Tech offers 0% interest finance options, allowing you to spread the cost over affordable monthly payments.
Ground source heat pumps can reduce heating costs by up to 60%, depending on your current system and energy usage. They achieve efficiencies of 300–400%, meaning for every unit of electricity used, they provide 3 to 4 units of heat.
The installation typically takes 3 to 5 days, depending on the complexity of the system and ground conditions.
For horizontal systems you’ll need at least three times your home’s total floor area.
For vertical boreholes you can allocate less space, but the distance from buildings is an important consideration.
Generally not, except if it exceeds 0.5 hectares or for listed buildings.
Yes, they are an ideal match due to providing consistent, low-level heat.
Yes, MCS-compliant installations may receive a £7,500 Boiler Upgrade Scheme subsidy.
Routine maintenance is recommended annually, with servicing costs ranging from £100 to £200 per visit. Regular maintenance ensures optimal efficiency and prolongs the system’s lifespan.
No, they operate almost silently due to their underground components.
The heat pump unit itself can last for 20 to 25 years, while the ground loop, which is buried underground, can last up to 100 years. Regular maintenance ensures long-term reliability and efficiency.
