Active heat recovery
The system exploits the energy stored in either the air or ground and converts it to heat via a heat pump.

Passive heat recovery
The system exploits the energy stored in the air extracted from the home and converts it to heat without the addition of extra energy.

Ventilation
The system extracts the stale, humid air from the home and draws in fresh, temperate and filtered air.

Comfort heating
The system heats the fresh air drawn into the home to a temperature level which reduces the energy consumption for central heating.

Comfort cooling
The system cools the fresh air drawn into the home relative to the outdoor air temperature.

Sanitary hot water production
The system exploits the energy stored in either the air or ground to produce sanitary hot water.

Heating
The system exploits the energy stored in either the air or ground to provide space heating via radiators or underfloor heating.
