How efficient is the HV?
The HV uses 116 watts (HV1000) or 276 watts (HV1600) of power while the fans are running, 6 watts when the insulated motorized doors are opening or closing, and 0 watts when turned off. The doors are insulated to R-22 or R38 model to minimize conductive heat loss or gain when the fans are not operating. Both doors are fully gasketed, like a refrigerator, to ensure a tight seal.
