Providing controlled and better ventilation for a healthy and comfortable indoor climate, while retaining the heat to an efficiency of up to 90%. The new Heatrae Sadia Advance Plus heat recovery unit comes with the additional benefit of an automatic 100% summer bypass. The summer bypass automatically opens when the outside temperature exceeds 20°C. During the summer nights when the outdoor air is cooler than the indoor air, warm internal air is taken straight through the unit to outside and bypasses the heat exchanger, whilst the outside cooler night time air is still filtered and supplied into the dwelling.
