Ground Source Heat Pumps

What is a Ground Source Heat Pump?

A ground source heat pump uses pipes buried underground to extract heat from the earth and transfer it into your home. The ground maintains a relatively stable temperature year-round, making GSHPs one of the most efficient and sustainable ways to heat (and even cool) a property.

Unlike traditional heating systems that burn fuel, GSHPs move natural heat — making them significantly more eco-friendly and cost-effective in the long run.

Key Benefits of Ground Source Heat Pumps

Exceptional Efficiency: Delivers 3 to 4 units of heat for every 1 unit of electricity used

Massive Long-Term Savings: Lower running costs compared to oil, LPG, or electric heating

Stable Year-Round Comfort: Reliable indoor temperatures, even in extreme weather

Minimal Carbon Emissions: A major step toward net-zero living

Low Maintenance & Quiet Operation: Eligible for Government Grants & Incentives (subject to availability in your area)

"Huge difference to our energy bills!"
We had an air source heat pump installed earlier this year by Tag Renewables, and we couldn't be happier. The house stays warm and comfortable even on colder days, and we’ve already noticed a big drop in our energy bills. It’s also reassuring to know we're using a more environmentally friendly system. The installation was smooth, and the team were professional from start to finish. Highly recommend making the switch!

"Outstanding service from start to finish!"
We recently had an air source heat pump installed by Tag Renewables and I can't praise the team enough. From the initial quote to the final handover, they were professional, knowledgeable, and genuinely helpful. They took the time to explain everything clearly and made the whole process stress-free. The system works brilliantly, and it's clear these guys really know what they’re doing. If you're thinking about going renewable, don’t go anywhere else — Tag Renewables are the best in the business!

Frequently Asked Questions

What is a Ground Source Heat Pump and how does it work?

A Ground Source Heat Pump (GSHP) is a renewable heating and cooling system that extracts heat from the ground using underground pipes. It transfers this heat to your home during winter and can also work in reverse to cool your home during summer.

How efficient are air source heat pumps?

GSHPs are highly efficient, typically delivering 3 to 4 units of heat for every unit of electricity used. This makes them 300–400% efficient, compared to traditional systems.

Can a Ground Source Heat Pump work in cold climates?

Yes. The ground temperature a few meters below the surface remains relatively constant year-round, so GSHPs can efficiently extract heat even during cold winters.

What kind of property is suitable for a Ground Source Heat Pump?

GSHPs are ideal for homes with enough outdoor space for horizontal pipe loops or the ability to drill deep boreholes for vertical loops. They work well for both new builds and retrofits with good insulation.

Are there grants or financial incentives available for installing GSHPs?

Yes. Many countries offer incentives like the UK's Boiler Upgrade Scheme or Renewable Heat Incentive (RHI) to help offset installation costs of GSHP systems.

How long do Ground Source Heat Pumps last?

GSHP systems are known for their durability. The ground loop can last over 50 years, and the internal heat pump unit typically lasts 20–25 years with proper maintenance.
