Power Sources for Heat Pumps

Underground water

Thermal energy is taken from water-wells of underground waters on depths of 40 meters in which water keeps its temperature in range from 10°C to 14°C throughout the year. Water is driven to heat exchanger which takes 4 to 5K (Kelvin) of water's thermal energy. After that water is returned back into the underground water-wells.

Ground

Implementation with horizontal tubes

The heat is collected from the ground using horizontal plastic tubes. There's a few circular water flows with parallel comprehension on 1 to 1,5 meter depth in which water circulates and keep permanent temperature of 5°C.

Implementation with vertical tubes

The heat is collected from the ground using vertical plastic tubes (sondes) buried on 40 to 100 meters depth in which water circulates and takes heat from the ground.
