Rated 4.4 out of 5 by 26 reviewers.
Rated 5.0 out of 5.0 by Exactly what we needed! My wife and I live in a house that was built in the 70's and never had a central unit installed. For years we've ran multiple 120v heaters in various places throughout the house (massive fire hazard I know!). On a recommendation from a family member I checked this heater out and am VERY glad I did. It came fully assembled in the box, all I had to do was plug it in. After paying an electrician $125 to wire a 240v plug in my living room, it was ready to go. I've now spent a total of $425 and my house (1400sq ft) is a comfortable 70 degrees with the new heater set just below the middle of it's dial. It cuts on and off with a decent degree of frequency and seems to be vastly more energy efficient than my previous heating arrangement (not to mention way safer!). Compared to the $8k I would need to have a panel upgrade and a brand new HVAC installation, $425 is pretty sweet to have this quality of heat in my home. If you are thinking to use this to heat a workshop or garage, I would assume you'll be very pleased indeed as it's currently heating my house just fine as I write this. February 25, 2015
Rated 5.0 out of 5.0 by Very Good Purchase I bought two of these heaters and both are exceeding my expectations. I wish I had bought them sooner. So far they are running great, heating the areas I bought them for 100%, and neither one has been turned up to their highest setting. February 17, 2015
Rated 5.0 out of 5.0 by Keeps up even when below zero I use this in my walk-out basement. The walk-out area is actually an uninsulated 9' garage door and a door with a dog door in it. The dog door flap lets in a considerable amount of cold air, little more than just a 18"x30" hole cut in the door. This little heater does a great job heating up the basement, approx. 450 sq ft to 63-69 degrees quickly. Outside temps will be below zero, the basement stays a constant 45-50 in the winter and this heater with the temp nob turned to about the 10:00 position heats up to 63 degrees in 30-45 minutes. My basement thermometer is behind the heater and about 8' away, it is getting no direct heat. The t-stat on the heater works perfectly, I am sure it would heat the basement more but I have no need to since I use it as a work area. I have had the heater for 2 winter seasons now, it routinely gets below zero and this unit keeps up no problem. It is a good buy, money well spent. I have mine mounted on the ceiling and I angle it towards the floor and the garage door. February 12, 2015
Rated 5.0 out of 5.0 by In use for 5+ Years I purchased radiant heaters to heat my insulated work shop first. They ran my bill up and were on all the time. I purchased this unit and wired it to an outlet that was controlled by a line voltage thermostat. It works great. It has two wattage settings. Normally I have it set to the low setting and keep the temp arround 50 degrees. When I am in the shop I set it on the higher setting and it raises the temp to 70 in just a few minutes. Built extremely sturdy. I am about to purchase another one for another space I need to heat. December 10, 2010
Rated 5.0 out of 5.0 by The Five Star rating says it all. First, let me state I live on San Francisco's East Bay. Winters here are most mild compared to the Northeast from wench I came. My workshop here in California was previously a 3-car garage with a 12' ceiling. The two 120amp space heaters were not doing a good job of heating the entire space; I had to place them but a few feet away from my work area for any benefit. After converting the circuit breaker box to 240amp it raised the temperature in the entire shop 10 degrees in an hour. Only downside I can expect is how much my electric bill will increase now that I've doubled the output. A small price to pay for being able to work in comfort. November 12, 2013
Rated 5.0 out of 5.0 by The real deal This heater is the real deal. It heats my insulated two-car garage with ease. It's 220 volts, so it's also efficient. I typically leave the heater on about 1/4 of the way at all times in the winter and bump it up to about 1/2 while working on projects, etc. I have not noticed any difference in my electric bill. I'm quite happy with this purchase. Sure, it's not cheap, but you get a great value in the long run. I've wasted much time and money in the past on portable heaters for my garage work shop. I've tried electric, propane and kerosene, which gives me a terrible headache. Propane is nice, but you typically only get about one workday per bottle of fuel, and that gets expensive and inconvenient. If you're looking for workshop heat, look no further. This unit is built well and does what it should without disappointment. FYI... You'll need a 220 volt outlet within 6 feet of the unit. November 29, 2010
Rated 5.0 out of 5.0 by Why change something that works so well I've had one of these heating my 24' x 30' garage for over 15 years now and it is still going strong. The garage is under the house and insulated. On the coldest days, 10 degrees or so, the garage is about 45 degree's and this heater will warm it easily to over 60 in little over an hour. For me that is a comfortable temp to work in. Of course on warmer days or letting it run longer it will get much warmer and it does keep up quite well not running continuously. All I do for maintenance is blow it out with the air gun on occasion. I'm glad to see these are still available all too often you find something that works right and they stop making it. If I ever need to replace mine I will buy this same one again no question. November 27, 2014
Rated 5.0 out of 5.0 by Outstanding!!! Keeps the Chicago winter outside where it belongs Over the past few years our cinder block walled maintenance shop would get down to 30 - 40 degrees in the winter here in Chicago. I purchased this in the hopes of at least taking the chill out of the shop so that we could wear a sweatshirt or something instead of our winter coats all the time. We put it up on the wall about 8 feet high and to our surprise it has not only taken the chill out of the room but actually made it comfortable. The shop is consistently in the 65 - 70 degree range even with the -18 degree below zero we had this past week. This heater gets 5 stars from us. January 15, 2014
