A building constructed with ENVIGA'S THERMO SCREW PILES™ and fitted with one of our ground-source heat pumps (GSHPs), is likely to be more cost-effective than a building constructed with traditional concrete foundations and fitted with an air-source heat pump.

Our GSHPs will be up to twice as efficient than air-source, halving the heating bill for the household, and potentially reducing the electrical energy demand to a level that net zero energy can be achieved with the use of PV, battery storage and gird export.
