Wolfgang Doemens:

In my new building, it was important to me to use a sustainable heating technology that meets all requirements without compromising living comfort. Therefore, it could only be a heat pump, because the heat pump is the only heating system that can heat and prepare domestic hot water as well as cool.

Ulrich Konen (CEO Lumitronic GmbH):

We have now installed several thousand heat pumps, almost all of them from alpha innotec. This has been my brand right from the start. Here I simply get really good quality and a lot of value for money.

Ground source heat pump


Compact is the synonym for small footprint and many already integrated components, which in standard heat pumps usually have to be mounted on the wall outside the unit. In the further development of the alpha innotec top seller, the possibility of combining it with other heat generators, solar thermal energy or photovoltaics as an important feature has also been consistently further developed. The machines cover an output range from 5 to 19 kW and can be supplied with a cooling function on request. With the many output gradations, the heat pumps fit into almost any object.


  • Can be combined with ventilation, solar domestic hot water support, wood stove or pellet stove
  • Highest domestic hot water comfort
  • Optionally also available with cooling
  • Flexible heating system for all needs
