Greenhouses need fresh air for CO2 and humidity control, but winter ventilation throws away expensive heat. An air-to-air exchanger recovers that heat without starving plants of airflow.
What to specify
- Sensible plate recovers heat; keep streams separated to avoid moving pathogens.
- Balanced airflow preserves effectiveness.
- Frost control for cold-climate houses.
Payback
Heating is often a greenhouse's largest variable cost. Recovering 70% to 80% of ventilation heat routinely pays back in one to two seasons, see the ROI walkthrough.
