Rated 4.0 out of 5 by 8 reviewers.
Rated 5.0 out of 5.0 by Great little garage heater I bought this to make it more comfortable while working in my 575 sq ft garage. Using the btu calculator this unit doesn't quite put out enough btu's to efficiently heat the space, but I decided to try it anyway. Tho it doesn't get up to 70 deg out there, it makes it comfortable enough to work in, while the outdoor temps are below freezing. Obviously it can get a little pricey if use it daily, so I just turn it on a couple hrs before I go out there. It runs most of the time, but again, it is small for the sq ft. Overall it does what I want it to do. February 4, 2014
Rated 4.0 out of 5.0 by Small in size ... but does a great job We were SHOCKED when the unit arrived. We expected it to be much larger in physical size (and we were okay with that, as this is being used in a commercial building), so we are delighted that it is not huge, as it looks much nicer than we thought it would. I am pleased with the appearance, the effectiveness and the price. April 1, 2014
Rated 4.0 out of 5.0 by works great My shop is basically the size of a 2 1/2 car garage and this keeps it from dropping below freezing. When I will be working in frigid weather it warms it up fairly quickly. January 7, 2015
Rated 5.0 out of 5.0 by Great Heater This little unit puts out a lot of heat. I added a plug to the end of the wire to plug in the unit. October 15, 2013
Rated 3.0 out of 5.0 by Good but could be better. The small size is great. Works well for basements, garages, and in process construction as a temporary heater. It could be more efficient if the fan continued to run for 30 seconds after the set point was reached, so it would cool down. A hot heater unit with no air flow can be dangerous and will shorted its life expectancy. December 11, 2013
