Same, our apartment complex has high-volume ventilation with heat exchangers in every apartment (The Netherlands). Humidity and mold has never been a problem and it's like continuously ventilating your house without the cold air. We recently replaced the gas heating and heat exchanger by an air-to-air heat pump that also acts as the heat exchanger and regulates the ventilation. Is a nice upgrade, because now the heat is fully controlled by one unit.
