Géothermic
How does it work?
A geothermal system is composed of pipes buried outside your home ( a closed horizontal or vertical circuit in which an antifreeze mix circulates or by pumping water from the ground), an internal circuit (under floor heating, radiators or blowing radiators) and a heat pump linking the two circuits.
A geothermal heat pump works on the same principal as a refrigerator:
- An evaporator (inside the fridge) recovers the calories through a refrigerating fluid that would be the equivalent of the pipes system buried outside your home.
- A generator enclosing the compressor rises the temperature of the refrigerating fluid, that would be the equivalent of the geothermal heat pump.
- A condenser (the grid at the back of the fridge) releases the heat into the water of the underfloor heating, radiators or blowing radiators.
The horizontal external pipe system
The tubes are laid horizontally 60 cm deep. Those tubes made of polyethylene or copper are pressurized and filled with an antifreeze mix or refrigerating fluid. This system requires 1.5 or twice the surface of the house to heat up.
The ground water pumping system
The circuit pumps up the water from the ground through a 8 to 50 m drilling according to the region you live in. The heat pump gets the energy contained in the water which is at constant temperature all year round.ant les régions.
The vertical external pipe system
Tubes are installed into 50 to 80 m deep drillings. Those tubes are pressurised and filled with an antifreeze mix. They recover the heat deep down through the antifreeze fluid circulation.
Isara – water to water system
This system allows you to heat all types of houses, room by room, in the winter and as a cooling system in the summer. This heating circuit is adaptable to all types of existing heating systems and can replace a traditional oil or gas boiler.
