Ok for first few months
After that, the thermostat quit working, so it was in all the time in the winter, which was ok in my case. ??It is the next season, and it worked for a few days, but now only the light comes on. ??No fan or heat. ?? It was the cheapest, rattled when it ran, and isn't high quality, but you get what you pay for. It died just past 1 year of course. I won't buy this brand again, but will shop Air and Water. ??

Nice garage heater
This is the perfect heater for a small 2 car garage. My garage is drywalled and insulated. If not all the heat would rise to the rafters. It took about an hour to take the chill off with temps in the 20's outside. I also put a simple box fan in to circulate the air even more. Nice product, great price.

Product came as Ordered
Theordering and shipping were as advertised. On-time and complete. Installation was easy and products works as advertised. It has to work hard if I want to raise the temperature in my 460sf garage, but it can do it. I bought it to keep the moisture out of my garage air during the winter by keeping the garage at about 52 degrees. It does that very well even when the outside temp has been in the 20's. It should work better when I have the garage fully insulated and rocked.

Excellent Garage Heater
I've had the unit installed for about a week and so far it's working perfectly. The thermostat feature is terrific and enables a consistent temperature setting. The fan isn't too loud and it quickly heats my 600 square foot insulated double garage. I'm also glad I bought the unit with the hanger since it keeps it high up off the ground and throws the air better. Only downside is it runs on 240v and I had to pay 4x the unit's cost to have an electrician install a new circuit/outlet to power it (unfortunately I'm not skilled enough) - but that's the price you pay for a electric unit powerful enough to do the job right. Now that it's installed and working I'm kicking myself for not doing this 8 years ago when I first set up the workshop in the garage!

Gentlemen, thank you for your interest in your product. Recently built a new workshop. The weather has been warm here in the Ozark hill country and have not needed heat. I purchased it to have ready for next winter. However, it is a very nice unit. It looks to be very well made. The mounting bracket made installation simple and effective. The shop was prewired for its installation. Thanks for including technical information on your wed site. The electircian knew what plug and wiring to install ahead of time. I am retired and looking forward to next winter and having a nice warm shop to entertain myself in. Thank you.

We use this in our garage and it gives out plenty of heat after it warms up. It only takes about a minute to get warm, it is a small furnace, make sure your room is air tight, that way you get more heat!!!

If I close off one side of the 2 car garage, I would be heating a 15 X 25 area. With outside temp in the 20's, my garage would go from 48 degrees to 55 degrees in approx 2 to 3 hours.....guess I expected more.

Bought this heater for a 2 car, 9 foot ceiling, partially insulated garage. I'm, very happy with the little unit. I turned it on when it was 40 degrees in the garage and 2 hours later it was 60 plus. Granted the heater is undersized for the space but it still performs well.

When I received the heater it was packaged well and there was no damage. I had my electrician son wire in a 20 amp 220 v circuit and I plugged it in and turned it on. The temperature was 44 degrees and after being on for 3 hours brought the temp up to 54 degrees. The space is a single car garage at 320 sq ft with no ceiling. The heater is only rated for 200 sq ft so it did ok considering the circumstances. I will get a larger unit next time. If I am working at the bench under the heater it is fine.

If you plan to heat an insulated garage that is a little over 500 sq. ft., this may not be the heater for you. It's just not strong enough. You will have to have it on all night @ the highest temperature and then your garage should be workable with a sweater. Overall it's a good working heater. It makes a little bit of noise, kind of like an old refrig.

I have used my Duplex Electric Garage Heater in my 3 season porch. It has heated it very well. I find the thermostat awkward to use. I have not been able to control the temperature with the thermostat. I will be using it in my shop this winter and will find out how best to set the control.

My workshop is in an unheated 2-1/2 car garage, and can get quite cool even though there is heated space above it. On cold days here in the mountains of western NC, the workshop temperature will drop into the forties. The heater is mounted near the ceiling in the middle of the shop and can be swiveled towards wherever I am working. On medium power it will raise the temp into the low sixties in a short time. I am very pleased with it.

Ordered over the internet and after looking at many units locally and on-line. I liked the size, output, thermostat feature and mounting bracket...and fact that these heaters can be mounted up on the wall away from any fire hazards or low lying flammable liquid vapors which are present in many garages with and without cars. I installed a dedicated 240v circuit for the plug. This is for a single car garage being used as a small shop. The unit heats up the garage well...allowing me work in comfort, even on cold days.

The Dimplex heater does a good job. My only objection is that it rattles sometimes during the heating cycles. Rattle seems to be the calrod element, cannot pinpoint. It stops rattling after a minute or so of heating. I have mounted the heater on the wall, above a window. I attached a small mirror to the wall in order to see the thermostat setting, which is also the on-off switch.

I purchased this heater to replace 2 1500 Watt oil filled heaters. The extra 1000 watts heats up the room much faster and does a good job of holding the temperature which solved the problems with the 2 slower and less efficient heaters. I found this heater easy to install. Well worth the money spent.

This unit was very easy to install right out of the box, I use it to heat a 20' x 20' garage (insulated), this unite heats it very well, does not take long to make a cold area warm enough to work. Wearing a sweatshirt, it makes it comfortable without making it hot, I would recommend this unit to anyone with a space the size of mine or smaller, does a great job for a good low price.

I have not installed it yet but my electrician tells me that I may need a bigger unit. When I install it, I will provide you with feedback. If I have to return it for a bigger model, I will provide you with my thoughts after that. That said, your company was a pleasure to deal with. The prices were competitive and the product arrived on time and as promised. Thanks.

Installation was simple. The wall bracket is well designed. My garage is a little over 400 sq/ft. The heater raised the temp. From 29-degrees to 50-degrees in 15 minutes. The temperature control is on the back, at the bottom of the unit. The control works perfectly. The unit is installed near the ceiling. It is not easy to access the controls without a ladder. I will be installing a 20-amp switch, 48-inches above the floor, below the outlet.

It works pretty much as advertised. I have a 3 car garage and partitioned one bay with plastic tarps. It was 20+ degrees outside and about 40 degrees inside. After an hour it raised the temp. about 10 degrees. After about 2 hours it was comfortable with a sweatshirt. Of course the tarps allowed some heat to transfer to the rest of the garage and warmed it also. Total space is over 800 sq' and this unit raised the heat in the whole space so that you could be comfortable with a jacket on. I think next year I will add another unit and heat the whole garage.

Good heater for the price. A little weak for a 3 car garage, but even then it is workable. If turned on early, then it will allow work in the garage area. Needs a remote or you have to stand on a chair to use it, especially if you don't plan ahead and put in a variable switch.

I use this unit in a basement workspace to take the edge off the cold when the furnace isn't running. The heater heats a large area (about 1000sqft)and raises the temp. 4 to 5 degrees quickly with no problem. the structure is pretty heavy duty and is easily adjustable. I wish it was a bit more quiet, but all forced air electric heaters are susceptible to a bit of vibration. Overall a nice unit for the price!

Did not want to hard wire heater. Had recepticle in place. Just fine. However, did not get Click to work when trying to adjust temperature. Packaging. I have never received anything so well protected in the mail. I do like the ease of mounting in different configurations. I will recommend it if it has the longevity that I believe it should. I was very very impressed with your website, and ease of ordering, plus the good pics which allowed me to see the 220v plug style.

Can you recommend a wall mount thermostat for the Dimplex DGWH4031 Electric Garage Heater?
- George C. on 11-29-2014
Answer:
I did not use a wall thermostat
- james n. on 11-29-2014
Answer:
I don't have any knowledge of a wall mounted thermostat for this particular heater. I use the one built in to the heater itself. I would think that wiring in a stand alone thermostat that connects to the dimplex would require a professional electrician and would probably be very expensive and outweigh the cost of the heater itself, especially when you can just use the built in thermostat. Hope this helps.
- Dylan M. on 11-29-2014
Answer:
I have owned two of these and just installed shop section of my barn. Thermostat is built into into unit on rear. It works fine, but has no temperature markings. You need to gauge settings and mark it based on thermometer. I use my current one in part of barn to keep it above freezing. I guess you could wire in a wall mounted thermostat to the unit, but it would seem unnecessary. On type of thermostat, you would to look at unit to see if line voltage runs through or not and the get the correct type. Manufacturer would be able to tell or look at schematic. Either type of thermostat is available. Hope that helps.
