Heat pump air to water

HOTJET s (split system)

Split system using the outside air as an energy source

The compressor is inside the house and the refrigerant temperature in the connecting pipe is low, the evaporator can be placed 20 meters away in the garden and to eliminate the noise problems and needed a place. 

• High coefficient of performances 

• Indoor and outdoor unit connected with refrigerant circuit

• Remarkably low sound level

35S optinal 2 evaporators.

50S standard 2 evaporators.

 

 

 Benefits

HOTJET s

  • The air compressor inside indoor unit, 
  • The evaporator outdoor unit
  • The evaporator can be 10m from indoor unit,
  • The losses of heat outside the house
  • Between indoor and outdoor units is refrigerant (not freeze)
