Explore the Heat Distribution Kit, your choice for optimal air exchange and temperature balance in different rooms. This ventilation solution perfectly distributes excess heat from a warmer area to an adjacent cooler one, making it an ideal addition to apartments, saunas, private homes and office spaces. The system has a built-in non-return valve that ensures air flow only in the intended direction, preventing backflow when inactive. The thermostat controls the ventilation fan, turning it on to transfer heat until the set temperature is reached. With Hot Air Distribution Systems, you can effortlessly distribute the temperature evenly between adjacent rooms.
