You name it, this house has it: an air-source heat pump, a rainwater harvester, central-vacuuming system, triple-glazing and motion-sensitive lighting system. It also features underfloor heating and self-closing loos. The five bedrooms are arranged over three storeys.
Geothermal heat pumps, or ground source heat pumps (GSHP) have been around for more than half a century. The technology exploits the constant temperatures we find right below the Earth’s surface, either for heating or cooling purposes, and has significantly higher efficiency than electrical heating, furnaces or even air source he
Geothermal heat pumps provide wintertime heating by extracting heat from a source and transferring it to the building. A ground source heat pump uses the top layer of the earth crust (usually three to 500 feet deep) as a source of heat, thus taking advantage of its seasonally moderate temperatures. In the summer, the process can be reversed so the heat pump extracts heat from the building.
Eco living: the Leicestershire home that powers itself - "Traditional rooftop solar panels are joined by more experimental technology including “solar walls”, which preheat air before it is pumped into the home’s ventilation system, and an “Earth Energy Bank”, which stores excess summer heat in super-insulated underground pipes, releasing it during the winter."
