Our best non-vented greenhouse heater
Designed exclusively for greenhouses, these open flame heaters keep your greenhouse cozy with radiant heat. The polished aluminum back reflects heat and distributes it through the greenhouse from the floor up keeping floor-level temperature within 5 to 7 degrees of the ceiling-level temperature for an uniform warmth. A wall mounted multivolt thermostat lets you specify the exact temperature desired from 35 to 75°F. A safety feature shuts off the gas if the pilot light goes out. No electricity is required so your plants are safe in a power outage. Extremely clean burning - the only by-products are carbon dioxide and water vapor, which are beneficial to your plants. Detailed instructions and venting recommendations included. 22" tall x 12 1/2" diameter. Stainless steel burner rated at 20,000 BTU. Propane models require 100 lb or larger tank (not included).
