In final steps of dismantling 100plus tank fish room. Heatilator is a wall-mounted air transfer unit that exhausts stale air and humidity out and brings in fresh air. Main feature is that it captures the warmth in the exhaust air to warm the incoming air. Does not require special wiring , but does require two exterior 12" exhaust and air manifolds.
Purchased for $946. Asking $250.
