Heater works just as it should

review-star review-star review-star review-star review-star
This heater works well in a 10’ x 13’ greenhouse. It can get temps to 85 degrees for seed germination, even with outside temps near freezing.
The accessory thermostat seems to be accurate.
I can only give it 4 stars because I haven’t owned it long enough to know how durable it will be.

Great addition to the heater

review-star review-star review-star review-star review-star
I originally tried to use the heater without this external thermostat but it was erratic and hard to control the temperature in the greenhouse. After adding this thermostat, it has been “set it and forget it”, the temperature stays within a two degree F range through the cold nights.
It was easy to install and the directions sent with the thermostat were easy to follow.

Greenhouse heating system

System is working well at this point. Was a little upset it wasn’t American made product like the old hulk. Waiting to see if it will cost less to run! Only loaded one photo. This is the greenhouse it is heating.

Just what I have been looking for!

review-star review-star review-star review-star review-star
Every 220 volt heater I could find was only available with a dial thermostat built into it. It has been my past experience that none of them are very accurate and tend to be the first point of failure. Finally I found one with a separate thermostat that I can place away from the heater! I now have the thermostat mounted where it is easy to read and make changes to, and it does not constantly cycle on and off like those cheap ones made into the heaters. THANK YOU!
