Smarter heating with Heliotherm’s modulation technology

Even SMARTER HEATING plus additional savings

with Heliotherm modulation technology®!



Infinitely variable modulation = heat output is adjusted to match the building heating load!

The heating load of a building is lower on hot days than on cold. The special regulation technology and modulating compressor in the Heliotherm heat pump take this into account and draw less current on hot days than on cold ones, by adapting the number of rotations. This enables you to save heating costs (electricity costs) effectively the whole year round.

Your benefits:

  • Up to 20% lower energy costs and savings on CO2 compared to conventional heat pumps! 
  • Longer lifespan due to gentle starting performance (starting current = operating current)
  • More flexible use of buildings with smart regulation technology – you do not need to heat unused rooms
Heat and save with Heliotherm’s modulation technology


Apart from the Heliotherm compact air heat pump, all Heliotherm heat pump systems
(within an output range of 0-18kW) are available in a modulating version.
