The Greenhouse Power Vented Unit Heaters are perfect for horticultural, commercial, industrial and agricultural uses.
- 80% thermal efficiency, maximizing seasonal efficiency through the use of a collector box and the power exhauster.
- A power exhaust that can be rotated 180°. The unit can be vented vertically or horizontally.
