Heat pump air to water

HOTJET i (indoor unit)

Using the outside air as an energy source.  

Designers of the HOTJET manage to fit our heat pumps in any small spaces of 0.5 m3. HOTJET-i can be installed in house interiors, e.g. in cellars, garages or in spaces for a building equipment. Atmospheric air is supplied and drained by air lines through a wall.
