Rated 3.5 out of 5 by 6reviewers.
Rated 4 out of 5 by Purchased for a 4 story staircase, installs easily and maintains temp to prevent sprinkler freeze ups, will recommend to others February 2, 2016
Rated 3 out of 5 by Have this heater installed in my garage and after 3 years it has stopped working. Thermostat appears to be calling for heat but heater no longer operates. Disappointed to say the least. Will attempt to replace the thermostat on the Heater Unit in the hopes that will fix it and hope it is not something bigger ( like the fan motor) or something. December 28, 2014
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
