Premium Preheat is suitable in buildings, where you want a combination of heat recovery ventilation and supply of comfort heating or cooling with the supply air. Before the fresh air is drawn into the house, heat is supplied to it in the counter current heat exchanger - heat recovered from the extract air. Then additional heat is supplied to the supply air by the heat pump and thereby it contributes to the home heating. If it is desired that cooling is supplied to the air instead, this is also possible. The supply air filter ensures that dirt and pollen is not brought into the house.
