The Thermpave® renewable energy system reduces reliance on gas or electricity for heating and cooling.
The system allows heavy rain to infiltrate through a permeable concrete block surface into a granular sub-base. The water is collected in a tanked area that combines with a layer of flexible piping connected to a ground source heat pump to generate 6 kilowatts of energy for domestic space heating and hot water.
The payback period on the system is typically between three and six years after which, other than the cost of running the heat pump, heating and cooling costs are completely removed.
In addition, the water in the system is cleaned by filtration and microbial action and is therefore also suitable for secondary non-potable uses such as flushing toilets and watering soft landscaping.
