The Modul-AIR Blue Exhaust Air Heat Pump (EAHP) and optional Climate Control Module (CCM) provides balanced mechanical ventilation with heat recovery (MVHR), domestic hot water (DHW), heating via radiators, underfloor (UFH) or fan coils & cooling.

It uses the waste heat from the extract ventilation through a heat pump cycle to provide the heating and hot water for the dwelling. When fitted with the optional CCM the supply air to the habitable space is pre-heated to increase the occupants comfort level and thus reducing the load on the radiators or underfloor heating in the dwelling. In addition to this in the summer months the heat pump cycle can reverse and provide up to 3kW of cooling via the CCM supply ductwork & an additional fan coil.
