HotJet w (water-water)

Many parts have been improved in the development of the new generation of water to water heat pumps: completely new design of unit, cooling circuit and control electronics.

Minimization of noise and dimensions were ones of the main requirements on this model and developers have successfully fulfilled them. Siemens basic control is also equipped with a cheap in use function of passive cooling. On your wish it is possible to deliver a unit with active cooling. Heat pumps of this model have output temperature up to +75 °C.

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

 

High technology with top electronics at a reasonable price
