Resource efficiency products

Water harvesting: Although not yet suitable for drinking and cooking, rainwater harvesting can provide water for things like laundry and toilets, saving up to 40% on mains usage. A rainwater harvesting system costs from £2000.

MHVR: Mechanical Ventilation with Heat Recovery provides fresh filtered air into a building whilst retaining most of the energy that has already been used in heating the building. Costs average £6450, with up to 50% energy bill savings.

Underfloor heating: Underfloor heating uses convection heat to create a constant comfortable temperature. Costs start from £2300, and is typically a more energy efficient way to heat a home than radiators.

Infrared heating: Infrared heating directly heats the walls, floor and ceiling of a building to build up thermal mass which then radiates back into the room. It has 100% energy efficiency, and costs around £75 per square metre to install.
