The TDA Exhaust Air Source Heat Pumps

Is a compact appliance which utilises aerothermal energy. It extracts heat from the ambient air, intensifies it and delivers it to the water in the tank. The unit is installed in a non-dwelling room with constant intake of fresh air. The condenser unit is a large aluminum coil wound around the water tank.

Due to its dehumidification capabilities the system can be installed in moist locations to balance humidity. The TDA-S model comes with a Heat Exchanger Coil meaning the unit can be used with different heat sources, such as Solar Thermal or Biomass. Convenient and compact design.
