Got the 240 Volt unit and installed independent line for it. Works very well indeed. Throws the air a long distance without being too forceful. On-board T-static switch works as it should. Of course greenhouses don't have much insulation, so am resigned to the fact that I may have to add another when the Winter really sets in. Only downside is that edges of stainless housing are sharp. They should edge treat the steel at the factory.

Received sooner than expected. Easy installation. Works flawlessly. We love it.

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.

I purchased this heater for a 130 sq. ft. lean to greenhouse. It's worked well this winter to keep the temps at 50 degrees with outside temperatures dipping below 20. Please with how quiet it is and it helps to move the air in the greenhouse. Build quality seems very good.

Seems to be working well. Anyhow its keeping my orchids warm. Jacksonville can get nippy in the winter with temps down to upper 20's.

I have been using this heater in my Grow More 10' x 13' greenhouse for several months, and the temperature had dipped into the lower 20s outside a number of times. The greenhouse temperature has been maintaining around 60 (where I currently want it to be) without any problem. Overall, I am very happy with this purchase.

So far, this heater has done a great job in my small greenhouse. It keeps the space quite warm, and it is very quiet. The coldest it has been outside so far is about 20-25 degree, and the greenhouse has been MUCH warmer than that with this heater.
