Heat Pumps from Hafner-Muschler: Eco-friendly, efficient and safe

Innovation meets tradition:

We combine almost 90 years of experience with innovative and sustainable energy concepts. For many years, Hafner-Muschler has been developing heat pumps and is producing them on series level. No product leaves our production without prior intensive testing and is delivered along with corresponding testing protocols.

For more information on the Heat Pumps made by HM, including an overview of the technical data and details of our series range, also please refer to our  Heat Pumps Brochure.

HM Heat Pumps – well positioned for the future:

  • Use of natural refrigerants, such as propane or ammonia
  • High level of planning and investment security
  • Certification acc. to DGNB standards possible
  • Simultaneous heating and cooling
  • Freely programmable control
  • Customisation (dimensions, container size, sound level, silicon-free construction, special temperature parameters and others)
  • Efficient raising of the usable temperature level up to 95°C

The HM Heat Pumps are able to use several sources simultaneously:

Ambient air - The ambient air is relatively warm also in winter. Our air heat pumps utilise the ambient heat at a temperature of, for example, -2°C and raise it up to approx. 40°C for the purpose of heating.

Energy stores - Energy stores allow collecting freely accessible energy surpluses simultaneously (energy from production processes, the environment, etc.) and to store and supply these energies on demand in the form of either heating or cooling energy.

Geothermal energy - Heat pumps equipped with heat collectors or geothermal probes use geothermal energy from a depth of 99 meters. From a depth of about 10 meters, the degree of heat of the earth amounts, all throughout the year, to approx. 10°C (efficiency through a low rise in temperature).

Ground water - The ground water is relatively warm also in winter. It is being taken from the earth, cooled down by a heat pump and, via an absorption well located at a different place, fed back into the underground.

Waste heat - Waste heat from sources with temperature levels ranging from, for instance,
-10 to 45°C (process heat, heat exchangers, exhaust air, solar systems, mine water, waste water, etc.), can efficiently be raised to levels within a range from 40 to 95°C.
