Outdoor units 

Daikin Altherma uses a natural source of energy.
The outdoor unit extracts heat from the outside air and raises its temperature to a level high enough to supply heating.
This heat is then transferred to the indoor unit through cooling agent pipes (thus, the additional advantage is that the pipes can never freeze).
The compact outdoor unit is easily installed and, as no drilling or excavation work is required, it can also be installed in flats and apartments.

Indoor units 

The indoor unit heats the water that circulates through low temperature radiators, 
floor heating systems or fan coil unit and also provides domestic hot water.

The outdoor unit comes in two ranges, 6, 7 & 8 kW and 11, 14 &16 kW (single phase and three phase).
This reversible air/water heat pump contains an inverter controlled compressor.
The inverter system constantly maintains the ambient temperature, which results in an energy consumption of 30% compared to a traditional on/off system.

The indoor unit is available in two versions:

 Wall mounted (EKHB*)

 Floor standing (EKHV*)

Both are available in a heating only or a heating and cooling model.
