The HRU ECO 4 ensures year-round comfort and low energy bills to occupants of the modern airtight home. While removing contaminated wet air from kitchens, utility rooms and bathrooms, the unit simultaneously introduces fresh preheated air to other rooms in the home.
The HRU ECO 4 diverts up to 91% of heat from the air leaving the building into the incoming supply. A 100% summer bypass valve prevents unwanted heat entering the home on hotter days, while, at the other end of the temperature gauge, a frost protection device prevents the unit from freezing. Suitable for homes with up to 175 square metres of floor space, the HRU ECO 4 uses less energy than intermittent fans.
