Mine looks different, but still a great heater!
I had been shopping for an affordable garage heater for some time, and I decided that this heater fit the bill. [...] Although I was confused by the substitution, I was happy with the price difference and once the heater arrived, I was unable to find any differences between the Oullet model I received and this Dimplex model that I ordered, other than the color. The pictures and specs all appear to be exactly the same. Since it's in my garage and being a Buckeye fan I like anything scarlet, I was happy with the red color and decided to keep and install the heater. Most reviews I've read on both models complain about the noise level. Well, when I removed the heater from the box it came in, I blew on the fan to see if it rattled or anything, and noticed that one of the blades clipped the electric motor while turning. I simply removed the metal cage, bent the offending blade ever so slightly so it no longer contacted the motor, and re-installed the cage. Easy, but definitely something worth checking before you install it. This heater requires a 220v outlet (see pictures of what the plug looks like) and since I did not have one in my garage already, I had to install one which I'd never done before. I needed 50 feet of wire, a dual pole 20 amp breaker, various pieces of conduit, a receptacle and a couple of junction boxes. I got pretty fancy with the receptacle (added a weatherproof plate over the receptacle, etc) and total cost to wire up the new outlet was about $70. You can certainly do it cheaper than I did, but be advised if you need a 220v outlet, it will add to the cost of installing this heater. I hung the heater on the wall using the included bracket, but it came with no screws to attach it to the wall. I went to the hardware store and bought two lag screws, and screwed it right into a stud. VERY sturdy installation, I could probably hang on the bracket if I wanted to. This heater really pushes a ton of warm air. It is a bit noisy, but the fan blows really hard so I can't really see how it could be any quieter and push as much air as it does. It has a nice dial-type thermostat on the back. It doesn't have a certain temperature that you can set it to, but you can just turn it on until it's as warm as you want it in the garage, then twist the dial until it clicks off. Then, it will click back on and regulate the temperature. I haven't tested it yet on a really cold day to see how long it takes to raise the temp, but I can tell you that with as much air as it moves, I'm confident it will work great. I'll update this review once I try it in really cold weather. Overall, I'm very satisfied, but just be advised, if the price drops about $50 and the heater ships from Northern Tool, there's a good chance you'll receive the red Oullet model. But it's a great heater and you'll save $50, so for me it was a win-win!

Works good not loud heats 2car garage
I bought this heater to replace my tank top propane heater. The propane heater works great, but it's loud and you need a fresh air source, additionally I need to cycle it on and off as it gets to warm and then to cold. The dimplex unit works great the built in thermostat cycles the heater for you. I don't expect it to warm up the garage from cold the way the propane unit did. If it's below 30 degrees F I will first warm up the work area w the propane unit. I will then set the dimplex unit on about 2 and it will maintain the temp in the low 40s. I find the low 40s comfortable to work in wearing coveralls. My 2 car garage is insulated w two windows, 2 man doors and 2 std garage doors. Compared to the propane unit the dimplex heater is quiet enough to hear the radio while it runs the propane unit was so loud talking was difficult. If you want to heat your workspace to 60 or 70 degrees you may want a larger heater or a smaller workspace.

If you get a good one, they're a great little shop heater.
I just bought my third Dimplex heater. I want to add my experiences to all the others here. I bought my first one about 10 years ago, and it has performed well, heating my 1000+ sq ft insulated shop. I keep it at 55 degrees, and boost the temp as needed. I have occasionally had to add extra heat if the outside temps are below zero. I bought a second one about five years ago as a spare. That one had a bad thermostat, I could not keep it at a set temperature, so for me it was basically either on or off. Unfortunately I did not return it in time, so I use it in another building when I am there to operate it manually. The fan on the original 10 y.o. heater started making bad noises recently -- ready to go out, so I took my chances and bought another. The third one is doing fine. So after reading many of the reviews, my opinion is that, rather that excersise good testing and quality control in the factory, Dimplex instead sends them all out and the customer does the quality control by returning the ones that don't work well. This is not the best way to run a business, but I think it keeps the price low. I like the price. I would buy another if needed, with the idea that I would test it well upon receiving it. I haven't seen any safety issues on the three I've had. I like the size. I like the fact it has a cord and plug. I like the durable element. My only complaint is that they are pretty noisy, but OK for a shop.

very good for where i use it
i mounted this heater in my basement as it was very cold down there. I did have to change the plug in end as I was unable to find one that matched it. Mounting was easy using the supplied bracket, and 2 cement anchors... I ordered a thermostat to be used with it because of the reviews i was reading. total install took about 4-5 hours. Before i turned it on my basement was 40 degrees, and within an hour it is a comfortable 65. The main floor of house feels warmer, and it does not run a lot to keep a pretty air tight basement warm. i like the run after shutting down the heat coil so it does cool off before shut down. I got lucky, maybe, as it is whisper quiet and runs smooth. it can only be heard in that one room in the basement. Some of the reviews talked about how the fan kicks in right away and blows cool air, then slowly gets warmer, but that is because if they turned on the element and then the air, the element would get very hot very fast, and this will greatly reduce life. I am pleased with this heater with its location. I dont think it is a hi output heater, so do some research before you order it. dont order it if you are borderline about going to the next size

I bought this a month ago. Also bought a 20 amp power outlet and had an electrician install everything as I wasn't sure how to do it. The unit itself comes ready to be plugged in. It's a little heater and I wasn't sure how great a job it would do. My garage is 15' x 30'. Once it was installed, I put it at the lowest setting. I just didn't want the garage freezing. The heater has maintained the temperature above freezing, even when the temperature outside was -22 Celsius (with a wind chill of -30 Celsius. I could keep the garage warmer by simply turning the dial up (and I tried that and it works!!), but I don't want to waste electricity -- just want to keep the garage from freezing and feeling damp. Great heater!! Very pleased with this purchase.

As far as the heater is concerned it looks like it will do the job nicely. I have a single car garage (250 sq. feet) and although it has not been extremely cold (about 5 C.) it heats up the garage nicely within a 1/2 hr, I purchased this heater because it is rated at 20 amps and has a 240 volt plug, 20 amps, I purchased this house a few months ago and saw that the previous owner had installed a 20 amp line from the circuit breaker panel. Here is what I think the issue is here. At 4000 watts the heater is drawing about 16.7 amps. This about 83 percent of the capacity of the line and the circuit breaker. 80 percent is the maximum safe load so this heater is marginal safe on a 20 amp circuit. I don't know how companies can get away with this. I've seen quite a few heaters advertised and sold as 20 amp heaters and have a 20 amp plug but I really question how they can say it meets code.

I spent decent amount of time choosing a proper garage heater. The ceiling options din't work in my situation cause I have suspended ceilings and also wanted a heat source pointing towards the garage door. This one does a good job heating up my garage quickly after opening the garage door. 4k watts is more than enough for my insulated garage of 280 sq ft. (I used 12 watts per sq.ft + extra just in case). It can be mounted to the wall or the ceiling which I really like. It also comes with mounting screws for wooded studs. On a cold start it does take 1-2 minutes to warm up to full heat. One of the disadvantages is the theromostat. I am not sure how accurate it is. Also it is impossible to set specific temperature, you will have to heat your room to the desired level and then dial it down until it "clicks" to maintain that temperature. Also not sure how the thermostat will behave when the power comes back after an outage. Overall, it keeps the necessary temperature so far. Overall, I am satisfied, good value for the price.

Seems to work well but so noisy I can hear it from my house while it’s running in the garage. It’s the sheer volume of noise that dropped the overall rating…a shame!
