Ground Source Heat & Cooling Pump |
A Ground Source Heat Pump transfers heat from the earth to useful heat for space heating and hot water. Three meters below ground level the soil temperature stays mostly at a constant 11C all year round. Heat can be usefully extracted from temperatures well below zero Centrigrade.
The usual method for the domestic market is vapour compression and expansion cycle in a similar way to a fridge but in reverse for heat. This sustainable technology uses electricity very efficiently consuming two to five times less energy than the most efficient condensing boiler. For each unit of electrical energy you put in can you extract up to 5 units of heat (in the UK typically 3.5 - 4 units of heat) this is called the coefficient of performance or COP.
An efficient use of this technology is with under floor heating or cooling with the most efficient use when in the summer the heat pump is used to heat a swimming pool and cool the house.
For domestic systems the Government's Renewable Heat Incentive has been delayed and will be implemented as part of the "Green Deal" initiative in Autumn 2012.
For commercial, metered, systems the Renewable Heat Incentive will be introduced in July 2011.
Our Treadlighter Plus energy survey includes a detailed suitability assessment leading to system design, specification and a complete installation, commissioning and certification service.
