Bio Green 240v Stainless Steel Waterproof Heater

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 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.

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.

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.

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.
