The Teratherm Heat Pump
Purpose-built to work with our Surface Thermal collector network. The Teratherm heat pump extracts energy from driveways and hardstanding at just 50mm depth, delivering COP 4+ efficiency for heating, cooling, and hot water, without boreholes, outdoor fan units, or visible infrastructure.
Unlike conventional air source systems, the Teratherm heat pump benefits from stable ground temperatures year-round, ensuring consistent performance regardless of weather.
Why Surface Thermal over Air Source?
Air source heat pumps extract energy from ambient air, which fluctuates significantly with weather and seasons. The Teratherm heat pump draws from a stable underground thermal store, delivering more consistent efficiency and eliminating the need for visible outdoor equipment.
- Stable ground temperatures vs fluctuating air temperatures
- No outdoor fan unit: silent, invisible operation
- Higher seasonal efficiency (SCOP 4+) across all conditions
- No defrost cycles required in cold weather
- Collector network doubles as a driveway or hardstanding

Domestic Systems
Surface Thermal heat pump systems for homes. The collector network sits beneath your driveway, feeding the heat pump for year-round heating, cooling, and hot water with zero visual impact.
Commercial Systems
Scalable Surface Thermal installations for commercial properties. Car parks, access roads, and hardstanding areas become energy sources, with cascade heat pump configurations for high-demand buildings.
Hybrid Systems
Surface Thermal heat pump paired with a gas boiler under intelligent control. The system selects the most efficient source automatically, ideal for properties transitioning to full renewable heating.
Teratherm Heat Pump FAQs
Common questions about the Teratherm Surface Thermal heat pump.
"The Teratherm heat pump was designed to work with our Surface Thermal Energy System. By drawing energy from stable ground temperatures rather than fluctuating air, we achieve consistent COP 4+ performance year-round. There is no outdoor unit, no noise, and no visual impact. For clients who want the efficiency of ground source without the disruption of deep boreholes, this is the solution."
