HOTJET i (indoor unit)

New generation of heat pumps HOTJET „i“ has a high level of functionality at small sizes while the price is still unbeatable. How did we achieve this? By optimization of the design, careful choice and serial production.

Company’s designers have developed a very compact design of the heat pump: it takes up just 0,5 m of space. Device is installed inside the building, in a garage or a technical room. Airway makes external air to come in and out through the wall. All models are equipped with Siemens controller.

Benefits:

  • Compact unit;
  • Indoor installation;
  • Guard cover is made of stainless steel sheet or powder coating;
  • The maximum flow temperature to 55 ° C;
  • Sound-optimised through low-noise axial-flow fan;
  • Central control of heating and heating of DHW;
  • Suitable for floor and radiator systems;
  • Wired and wireless control;
