B. Dehumidification of a wet room
The heat pump can be installed in laundries or other wet locations to take advantage of dehumidification in these rooms where humidity is often abundant.

 Heat Pump Schematic - Heat Recovery

C. Recovery of heat
The air is extracted from the outside where heat is available for free. The heat pump can also harness the energy produced by lighting, appliances, showers, bathrooms, etc. The recovered heat can thus be used for the production of hot water.
