An ERV/HRV System for your Home
An Energy or Heat Recovery Ventilation System (ERV and HRV respectively) provides your home with fresh air all year round without disrupting the internal temperature. This calculator helps you to determine which system would be best for your home. You can choose to either enter the floor area and average wall height of your house, or, if it’s easier, the number of rooms:
Floor Area (m2)
Average Wall Height (m)
N.B. An appropriate decentralised solution to ventilation is highly dependent on the position of each room of your house in relation to one another. For a more accurate analysis, send us a copy of your floorplan for a free estimate.
