How does an iDM heat pump work?

Our heat pumps heat large areas in underfloor or wall-mounted heating systems. Rooms are kept comfortably warm at all times, even at low heating temperatures.
No soot, smoke or wood dust can impair the air quality. If the heat pump is operated with ecologically-friendly power (e.g. hydropower, photovoltaics, etc.), the entire energy generation process is completely free of emissions and is CO2-neutral.

Heat and energy from nature are available for free – an advantage that pays off:
4 x environmental energy + 1 x electrical energy = 5 x heating energy.
In principle, the heat pump works like a refrigerator: Refrigerators extract heat from food and release it back into the room via their backs.
A heat pump also obtains heat from air, water or the ground.


iDM air source heat pumps use the outside air as a heat source. They are easy to install and almost invisible when installed indoors.

deep drilling (GROUND)

Ground source heat pumps (brine/water) use geothermal heat as a heat source.
Geothermal heat pumps can operate all year round with constant temperatures from the earth.

direct evaporation (GROUND)

The direct evaporation is a perfect and cost-effective alternative to the brine flat collector.
Here, the solar pipes are laid in loops in a trench with, for example, a width of 2 m and a deep of 1. 5 m.

flat collector (GROUND)

The flat collector draws its energy from sun and rain. This means that the ground above the surface collector must not be sealed: no asphalt, concrete or similar.
Even deep-rooted plants may not be planted on the area used.


Groundwater heat pumps (water/water) use heat directly from the groundwater via two wells.
