Performance & Metrics
Maximum Efficiency.Zero Deep Drilling.
Surface Thermal Systems harnesses the massive thermal potential of your existing footprint, delivering SCOPs that rival deep borehole geothermal systems.
What makes a heat pump truly efficient?
Heat pump efficiency is measured by the Seasonal Coefficient of Performance (SCOP). This indicates how much heat energy is produced for every unit of electrical energy consumed over an entire year.
"If a system has a SCOP of 4.0, it produces 4kW of heat for every 1kW of electricity you pay for. That is 400% efficiency."
The Physics of Surface Thermal
Traditional Ground Source systems rely entirely on ambient ground temperature deep beneath the earth.
Surface Thermal turns your driveway into a massive active solar collector. It harvests solar radiation, ambient air temperature and stable ground temperature in phenomenal recovery rates and high source temperatures that drive exceptional SCOPs.
Built for Maximum Yield
Engineered to extract every joule of available environmental energy from your existing footprint.
Extremely High SCOP
Achieve 400-500% efficiency (SCOP 4.0+), delivering 4-5 units of heat for every 1 unit of electricity.
Massive Solar Absorption
Dark surfaces like tarmac and resin bound stone act as giant solar collectors, rapidly absorbing solar radiation.
No Defrost Cycles
Unlike air source systems, Surface Thermal doesn't lose efficiency to energy-wasting defrost cycles in freezing weather.
Rapid Thermal Recovery
The immense surface area of a driveway ensures thermal recovery is almost instantaneous during daylight hours.
The Defrost Dilemma of Air Source
Cold Air Drops Efficiency
As air temperatures plummet below 5°C, Air Source Heat Pumps (ASHPs) must work significantly harder to extract heat, causing their efficiency to drop precisely when you need it most.
Wasted Energy on Defrost Cycles
In freezing damp conditions, outdoor fans ice up. ASHPs must reverse their cycle, taking heat from your home just to melt the ice off their own coils—a massive waste of energy.
The Surface Thermal Advantage
Surface Thermal is buried beneath the paving, protected by strict engineering margins and massive thermal mass.
No fans to freeze over
No energy-wasting defrost cycles
Consistent high efficiency through deep winter
