This heater is about useless. The fan is does a good job circulating and the thermostat works which concludes the pros. The heating element could not maintain a 10×10 greenhouses temperature.
ACF Greenhouses: I'm sorry you are not satisifed with the heater and are welcome to return it for a refund. We highly recommend using our
Heater Size Calculator before purchasing a heater for your greenhouse. It is easy to underestimate the amount of heat needed for a greenhouse because it has so much less insulation than structures like a home or garage.
