Rated 3.5 out of 5 by 4reviewers.
Rated 5 out of 5 by I bought this heater to heat my 400 sqft garage with 10' ceilings. This heater worked perfect. It only takes about 20-30 min and the garage was nice and warm in the winter. September 1, 2013
Rated 2 out of 5 by I would not buy again. 1 yr and 3 mo after installation the unit will not shut off. Time to replace the thermostat/switch.... after only one year. The previous heater (other brand) we had in this location lasted over 5 years. Not very impressive quality. March 14, 2013
Rated 2 out of 5 by A lot weaker than I thought it was going to be. Worked fine for a few weeks, then thermostat wire cooked on the thermostat. For the life of me I can not find a new thermostat for sale anywhere. The fan is so weak it might have been overworked. March 6, 2013
Rated 5 out of 5 by I bought this unit for my Garage, approx. 400 sq.ft. and it has worked flawlessly for nearly six years now. I use it to heat my garage, I live in the Northeast and I have many valuable materials in the garage that I no longer need to carry to my basement. I recommend this unit for anyone looking for a reliable space heater. January 8, 2013

One of the wires on the front controller completely burned off so that the unit didn't work. I replaced and soldered a new wire, and now it runs constantly. Can the controller be replaced, or do you have another suggestion?
Thanks.
