Soil-water heat pumps
Geothermal energy is the energy stored in the earth in the form of heat.This energy can be used through a heat pump.
The heat pump is basically a 'heat pump' that can 'extract'and focus heat from a primary source, using electricity.The yield (also called COP coefficient of performance) is positive,consuming 1 kW to produce the equivalent of about 2.5 ÷ 5 kW.
Such a system consists of:
- thermic source (earth or water)
- probe (mounted horizontally or vertically)
- collector distributor
- heat pump
