I purchased this product to heat my 24x24 (7'6" ceiling) garage under my house. During the coldest periods where I live (Western Connecticut) the garage gets down to the low 40s.
After installing the heater and powering it up, in about 10 minutes the chill is gone from the space. After about an hour the space is very comfortable (about 62 degrees an increase of about 15 degrees from when it was turned on). By the end of the second hour the space warmed to 68 degrees. The built in thermostat turned down to about 3/4 maximum maintains that temperature.
The unit's internal fan is a little bit noisy, but since the unit is intended for a garage/workshop the fan noise is in my opinion not a big deal.
The unit is very well made and easy to install. After installing a 220 Volt 20A single circuit receptacle, I hung the unit in the center of the room from the ceiling about 4 feet from the rear wall of the garage. The bracket that came with the unit is very sturdy and will accommodate several differnt mounting options.
If you had a bigger space or an uninsulated detached garage, a larger unit with more capacity will be needed (5000 watts or more), however for a single car garage or a well insulated two car garage this unit is an excellent value.

I have a 24x24 garage with 10 feet ceilings. I did exactly as the last review did, mount it on the ceiling about four feet off the wall. Don't expect this to heat your space quickly. It works quite slowly and you can't really notice the heat, which I think is great. I turned it on at 4am in the morning and the garage temp was 40 degrees. After about 15 minutes, temp was up to 43 degrees. In about an hour it was up to 52 degrees and after 90 minutes it was up to 60 degrees. This unit is quality built and extremely quiet. It lacks the bell and whistle but is very inexpensive compared to other units. It only requires 240 volts and 20 amp breakers, all standard in the home. ( the other heaters require 30 amp breaker which requires more cost). it also come with a cord which save you another $40 over the other models. I highly recommended this unit as it compares well with the 5000 watt units with out all the extra cost. Plus if you want it to heat up a small area in the garage a little quicker then go buy a $40 floor heater and you will have the best of both worlds. Enjoy !

Installation was very simply and it does the job of warming up my garage. However......
It's only been in use for about 2 months and the built-in thermostat sticks so the heater doesn't shut off at it's preset temperature!!! It just stays on full heat!!! This could be a hazard!
Instead of going through the headache of sending it back for warranty service, I'm just going to buy a programmable thermostat rated for this unit and controlling it that way.
I would not buy this product again due to the thermostat problem. The built-in thermostat is very cheaply made aparently. Quality should be paramount due to the type of unit that it's in. I should have looked for a unit made in the USA. This unit is, like most everything else, made in CHINA.
*************************
I've installed a programmable thermostat and it's working great, since it's not being controlled by it's built-in thermostat.

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!
Want Dimplex DGWH4031 4000-Watt Garage/Workshop Heater Discount?
Pleasantly surprised by this heater. I was in the midst of finishing my detached oversize two car garage and the heater choice was on my to-do list. I was going to require about 16000 BTU with standard insulation in my climate (Syracuse NY), which would equate to about 4800-5000W electric heater. Since I was over insulating the garage walls (R17 walls, R40 ceiling), I was confident I could get away with a slightly smaller unit the 4000W Dimplex. If needed I can supplement in a local area of the garage with a small 1500W space heater that I already had.
Installation was straight forward, since I was putting in all new electrical circuits in the garage anyway, it was easy enough to add the dedicated 240V circuit for this Dimplex unit. My unit required a NEMA 6-20 recepticle.
I started using the Dimplex unit with only some of the walls insulated, and was pleased that I could get a 10degF increase in room temperature in about 60-70 minutes even with the outside temp being 22-25 (starting temp in unfinished garage around 32degF).
I do not anticipate a large impact on my electric bill. I pay $0.05 (5 cents) for 1 kWhour. This ia 4kW heater, so for one hour of run time I pay $0.20 (20 cents). The heater will likely get used for about two hours a day ($0.40), for a total of about $12 a month.
Why only four stars? Well my only complaint about the heater is that it doesn't have a built in fan delay. When the unit kicks on, it powers the heating element and fan right away. So the fan is blowing cold air over a heating element that isn't up to temperature yet. This is a very small annoyance and a small inefficiency of the heater. The heater does have a shut down delay on the fan, it will keep the fan blowing over the hot element when the thermostat kicks the element off. This extracts and distributes the remaining residual heat from the element. Still the start up fan delay would have been nice.
