Rated 4.3 out of 5 by 29 reviewers.
Rated 4.0 out of 5.0 by Good bang for your buck The Heater is quiet and heats my insulated 2 car garage in no time even on a cold winter night (Montreal QC) and I have 12 ' cielings. I find it great value for money so far. I'm not sure how it will last long term as I only just got it but it seems well made. That being said I intend to find my own thermostat that I can leave inline with the heater as a backup. (I had a friend with a similar heater who came home to find his heater thermostat failed and it was running constantly. The plug was melting and he had to turn it off at the braker) January 16, 2014
Rated 5.0 out of 5.0 by Excellent value Used this to heat my 12' x 20' workshop. Good heat output and fan is quiet yet powerful. May 3, 2014
Rated 4.0 out of 5.0 by Compact efficient heater This heater works well, not too heavy, well constructed, reasonably priced. The only problem I had was the plug, which I have never seen in western Canada. I had to replace it ($15.00, Home Depot) with one that would fit my welder extension cord. November 16, 2013
Rated 4.0 out of 5.0 by Good Heater This is the third heater I have tried, all were 4800W units and the first two were from other stores not Home Depot and not Dimplex brands, the first two did not heat up as quickly and were extremely noisy, one vibrated so badly it almost fell off the shelf I made for the heater and fan sounded like it was shredding leaves. This Dimplex is the quietest I have tested, can hardly hear it when it's on in my shop, and provides great and quick heat. Last night it was below freezing and I was a comfortable at 65 degrees F inside my 14x28 fully insulated with 8' ceiling garage (R12 walls and R20 Ceilings). Only complaint is when the unit shuts down, element is extremely hot, fan should have a delay and run until element cools as a safety feature and to take advantage of the residual heat in element, just keep unit at least 1 foot from anything that may be effected by this residual heat and it's fine. Other than that it is the best I have tried so far, would recommend this unit. November 29, 2012
Rated 5.0 out of 5.0 by Very HOTT Little Box !!!!! This is one hot little box..... A lot of heat out of a small package, Measuring only 9 wide x 13 high X 8 inches deep this thing puts out a ton of heat for the price, All I had to do was change the plug so I could use the same 220 volt receptacle I use for my table saw. Has a built in thermostat that works well, I am using it to heat my Poorly insulated one car garage shop/lounge, in the morning it will raise the temperature to a comfortable 70 degrees in about 15-20 minutes when its 20 degrees outside. They must have made some improvements as I did not think it was loud.. With the TV on I cant even hear it running. I had another 5000 watt made by a competitor and it died after 2 years, was twice as noisy and didn't put out as much heat even though it was larger. I dont think you can go wrong for the price and it looks well built as well February 7, 2015
Rated 5.0 out of 5.0 by As Advertised! Great Value! Initially thought I made a mistake when unit was delivered. It was way smaller than I pictured it. Hung it from the ceiling, plugged it in, and WHOA! You can bake cookies in my oversized one-car garage now! Quiet, looks good, well constructed, hung it from the ceiling. Love it! January 29, 2014
Rated 5.0 out of 5.0 by Great little heater for construction projects -- with a 220v outlet We are working on a major remodel for a home in Wareham, MA. The project schedule slipped (as always!) and the old furnace in the basement was inoperable. Frozen pipes and damage to building products became an issue, not to mention trying to make our team work inside a refrigerator! With months of work remaining through the winter, a temporary propane / fuel fired heater did not make sense. An electric option with a thermostat was best. I reviewed a number of products and picked the Dimplex 4800 watt unit from Home Depot. It arrived on schedule, just before the first big freeze. I was surprised by the small size of the heater -- but when I plugged it in, wow! We put it in the basement and it kept the basement warm (and the upper floor above freezing). Our contractor slept in the basement one night and said it was "toasty" and comfortable. The heater does require a 220v outlet -- which is essential to provide significant heat. If the home does not have one, it should be quick and cheap to install; ours cost $50. This gives me an opportunity to recommend another Home Depot product: foam board insulation. This house had old fiberglass bats in some walls, and no insulation in others. We filled all of the stud bays with foam board and sealed the edges with cans of spray foam -- all from Home Depot. This created a tight air barrier, plus 4" of insulation. We also 'wrapped' the house with 2" of XPS on the outside. The result: that little heater now keeps the entire house warm when it is 20 degrees outside! 4800 watts = 16K BTUs, so this is a great real-world example of the effectiveness of good insulation! The homeowner will be very happy with the heating and AC bills. December 10, 2013
Rated 5.0 out of 5.0 by WORKS FOR ME I live in Arizona so it's not like there is snow on the ground but our winters can be cold. My shop is 800 sq ft with a 12 ft ceiling. It has fiberglass insulation in 2 x 4 walls and in 2 x 6 rafters. If it's 50 degrees when I get there, this heater takes it to 70 in about 1 1/2 hours. I use a box fan to circulate more air in the shop which seems to help distribute the heat all around. I set the heater on the concrete floor. you will most likely have to change the plug end it comes with. I did. My heater rattled a bit when I first tried it out. After it cooled I opened it up and bent the coils a little to eliminate that problem. That's the only issue I've had. It's fan does not run after it reaches temp, so give it time to cool before you handle it. I have only had it for two years but so far so good. December 13, 2014
