Heat pump water to water

HOTJET w (water-water)

New generation of heat pumps water to water a very new design of casing and control electronics. Simply we have to say that “ not a stone was left standing” compared to the original model.

Minimisation of noise and dimensions were ones of plenty requirements on these models. Even basic control technology Siemens can ensure very cheap operational passive cooling.

On your wish it is possible to deliver a unit with active cooling. Support of passive or compressor cooling, Optional workmanship version with output temperature up to 75°C, Destined for unmanned, fully automatic water heating up to 55°C, More constant output from earth or water, Higher heat coefficient, Without aerodynamic noise, Compact design with extremely low space requirements (ground plan 0.35 m2), As heat sources there are an earth collector, a borehole or a water well, Central control of heating and warm service water warming-up by means of delivered heating controllers, Effective and efficient corrosion protection

Advantages over water-to-water heat pumps


  • more stable heat output
  • higher COP
  • without fan noise
  • run without the influence of weather
