Why do I need to have the Ventilation kit with the GreenGro heaters?
All heaters require ventilation to support combustion and for proper operation. In the conventional gravity or power vented heaters, ventilation are built-in to the greenhouse as the heater is using the inside air and of course outside air being drawn inside the greenhouse for combustion and 20% or more of the heat and the product of combustions (CO, CO2, NO2, NOX, ethylene etc) are vented in the atmosphere which results in inefficiency. Also, once the vented heaters are operational, to keep the presure/air balance, cold air is being drawn from any infiltration in the greenhouse further reducing the inefficiency to 65-78% efficiency. In dollar terms, if you’re spending $10,000 for the heating season, $6,500 to $7,800 are being spent in heating the plants while $2,200 to $3,500 are being wasted into thin air. Any leaks from the heater to the smoke stack for a vented heater inside the greenhouse would be devastating to the plants. The same can be said of any leaks from either natural gas
