Positioning on the soil using a circuit with Sol liquid:
Hundreds of meters of a plastic tube are laid at a soil depth of about 1 - 1.5 m. Thanks to the re-circulation pumping of the antifreeze (Sol) heat is extracted from the soil.
Cooling. Cooling is possible by reversing the process.
For a calorific power of 10 Kilowatts, from 500 to 600 meters of tubes are needed, or from 230 to 360 m² of soil surface.
50-year warranty for the plastic probe-tubes!
Positioning on the soil with direct evaporation
Copper tubes with a plastic protective lining are laid horizontally on the soil. The liquid for the heat pump flows directly in these tubes.
As a result, it is not necessary to use an additional re-circulation pump. Direct evaporation makes it possible to obtain extremely high efficiency levels in the energy performance.
For a calorific power of 10 Kilowatts, from 380 to 450 meters of tubes are necessary, or from 230 to 360 m² of soil surface
Remains unaltered for more than 50 years!
In-depth hole with circuit by means of Sol:
A geothermal probe consisting of plastic tubes is inserted into a hole dug deep into the ground.
Heat is absorbed through the re-circulation of the Sol fluid deep in the ground and its return.
For a calorific power of 10 Kilowatts, one or more probes inserted at a depth of 100 meters are necessary, depending on the characteristics of the soil.
The plastic probe-tube remains unaltered for more than 50 years!
Hole dug deep in the ground with IDM Direct cooling
At a depth of 20 meters, there is a constant temperature of +10°C (no seasonal fluctuation).
In the wintertime, this constant offers a warm temperature while in the wintertime it provides an ideal cooling.
