Rated 4.7 out of 5 by 20 reviewers.
Rated 5.0 out of 5.0 by Works like a champ! Installed this in my 22'x32' garage/shop and for the first time the garage is a cozy place to hang out and make wood chips. Staying at a comfy 70 degrees with low settings. Well made, quiet and seems to be a quality made product. The only noise from it is the sound of the air being pushed. Fan comes on and off with heater. Mounted it sideways on the wall so the air can be redirected so as not to blow dust on projects when finishing. The bracket may need additional support for this application, it isn't designed for it and sags a little. November 19, 2015

Rated 5.0 out of 5.0 by Nice Heater I have a well insulated double garage. It does a great job of warming the space. I really like the fact that it is so quiet. I hung from the supplied bracket near a 220 outlet. Works great March 27, 2015
Rated 5.0 out of 5.0 by Hot One Garage Heater I have 2 of these heaters in my 30 x 32 garage. They have been in use for 7 years with no problems. It gets very cold in Minnesota but these heaters do the job even on a medium setting. They replaced an LP ceiling mounted furnace that cost more to run than these 2 Hot Ones. I restore collector cars so a heater that works 24/7 is a must. They are built like a tank and I am very happy with them. It is nice getting in your car on a sub 0 morning and it is all warmed up for you. My friend saw how mine worked and he bought one for his garage and is happy with his also. Great heater.

Rated 5.0 out of 5.0 by "cadet heater/a little workhorse" I've owned and used this product in my 20 x 40 cabinet shop for 4 years. I did extensive shopping before deciding on this heater. It is by far the best value for the money. For such a small unit it puts out a great deal of heat. Easy to install, operates very quietly. I'm purchasing another one for my garage. November 3, 2006
Rated 5.0 out of 5.0 by A "MUST HAVE" for the shop ! Bought this jewel for my small cabinet shop in Maine, it's always comfortable and I keep it on the low setting. I mounted it 6' off the floor in a corner so it blows diagonally across a 24'x28' area, when it does come on, it heats the place quickly and quietly. I definitely recommend this for the garage, cellar or small to medium shop! September 30, 2008
Rated 5.0 out of 5.0 by Great Purchase I have a small woodworking shop (250 sf) and was using an unvented propane heater for heat. This did not allow me to keep heat in the shop at all times. I researched other means of heating and decided to try the 4000 watts 220 heater (Hot One). Coming from Home Depot I knew that if I was not totally satisfied I could return the unit at my local Home Depot store (great folks to deal with). I have used the heater for about a month and I am 100% satisfied with performance. I have only used the high setting once, which was to test the unit; otherwise, it is always on low and provides more than adequate warmth. The thermostat feature also worked perfectly. Money well spent – should have done this years ago. February 23, 2010
Rated 5.0 out of 5.0 by My work shop is 24'x52' with a 10' ceiling, partitioned with garage at one end and workshop at the other end. I use the electric heater to replace a much larger gas furnace for my wood work shop. I have found the thing to work really well, even in the 20 degree weather that has gone on for more than a week, the heater does not run more than 50% of the time, probably less than 20%. And the temperature is comfortable. When I first got it, I mounted it on a low stand but that was in the way so I mounted it 7' above the floor. PERFECT. January 19, 2007
