Heat output is exceptional. Comes wired for 5000 watts, which puts out VERY hot air. Hand held 6" from louvers is too hot to leave there after 9 seconds.

INSTALLATION SAFETY WARNING: Unit mounts to inverted U-shaped bracket via bolts on left & right sides that settle into "keyholes" in the bracket. I slid each bolt down into the keyhole and tightened them medium-snug. The bottom panel of the heater hinges downward to accommodate wiring the 240V incoming power. When finished, I pushed/slapped the panel firmly to close it, and in so doing knocked one of the mounting bolts up & out of its keyhole, causing the heater to begin to fall. I caught it without harm, but if I'd been on a ladder, or if both bolts had popped loose, I might have lost some front teeth...or worse. Just thought I'd mention it to maybe prevent an accident. If you choose to go the plug & socket route instead of direct wiring, this won't likely be an issue, but I've wired many ceramic kilns and have seen the toll that resistance heating takes on plugs & sockets (melted brass/copper/plastic & smoke), so I prefer direct wiring.

Instructions specify #10 copper wire (3-wire: 2 conductors plus ground) and 30 amp breaker to use the factory setting of 5000 watts. A diagram is provided inside the bottom access panel for changing jumper wires for lower wattage output with correspondingly smaller wire and breaker options (as low as 15 amps at 2500 watts...but then why buy this heater??). I had to run a brand new circuit, and since I had #12 wire on hand I was tempted to lower the wattage enough to go with #12 wire and 20 amp breaker, but the manual suggested going with #10 & 30 amp in case bumping up to higher wattage was desired at some point in the future. That made good sense to me, so off to the big box store I went to get heftier wire & breaker, and I'm glad I did.

That little red light by the thermostat is NOT a "power on" indicator -- as one might assume of a little red light by a thermostat (!), but rather an alarm light that will only come on if the unit overheats. (When I first turned on the heater, I wondered if the light was faulty -- until I looked it up in the instructions...)

As others have mentioned, don't expect the fan to come on right away when you turn the knob clockwise and hear the thermostat click; the elements may need to warm up for awhile (a couple minutes in my case) before the fan will kick on.

Yes I knew this before I bought it, but at this price point it would be nice if the manufacturer would include an on/off switch on the front panel, with an "on" indicator light.

The elements are completely encased in metal tubing, which is nice; not exposed coils like many utility heaters.

Mighty for its size, blistering hot output, definitely recommend.

Purchased this heater for a three car, ~ 700 square foot, insulated garage. Temperatures in the hi plains dip to the 20s and the teens often during the winter, and the wind is always a factor. Also purchased 25' of 10/2 w/ ground via Amazon Prime. Had to get the 30 Amp DPDT circuit breaker from a local big box store - that ran about $9. Figure I'm in it for just under $290.

Heater comes wired from the factory to put out 5000W but, from the instructions, I gather that one could change some wiring around to reduce output. Based on the size of my garage, I stayed with the factory setting. I selected a location within 25' of the breaker box and had to install a couple of 2 x 4s in order to support the hanger, as I have a finished ceiling. Then ran the Romex from the 30 Amp breaker to a newly installed electrical box at the back of the heater. Used flexible 1/2" conduit from the box to the back of the heater. There is a large, hinged, door at the bottom of the heater that allows for easy access to the connections. Wiring was straightforward - all you need are the two 10 gauge wires (one black, one white) and the ground. Once I connected to the breaker, I threw power to it, and it was cranking out heat in no time.

The heater is smaller than what I expected so, consequently, takes up little room on the ceiling. The last few days have seen temperatures sustained in the 20s. I've had the heater running for about the last 48 hours (cycles on and off), and it has kept the garage at a very comfortable temperature. Again, I have an insulated garage and, to me, comfortable is in the 55 - 65 degree range, when the temps outside are in the 20s and teens. Best part is that I have not had the thermostat above halfway, and it maintains the garage comfortably and does not run too often.

Very pleased with the quality of the item, the ease of installation, and performance so far. Cannot comment on how the heater will affect my utility bill until next month but I don't expect it will be too drastic, as it does not run that often. Based on my limited experience, I recommend this item for similar situations/installations.

All the above is personal opinion, based on my experience. Your mileage may vary,

Hey, no nonsense heater when the power goes out you don't have to reset like other heaters on the market. Well made sturdy construction simple design.

I installed this heater in my insulated 3-car garage with a 10' ceiling. I live in the Pacific Northwest so our winters are mild compared to the east coast, but when the outside temperature is in the high 20's or low 30's I have no trouble heating the garage to a very comfortable temperature in less than an hour. I agree with one other review that the fan noise level compares to the sound of a box fan, maybe on low or medium speed. Much quieter than the last garage heater I had and very acceptable to me. The heater has adjustable vanes to direct air. I connected it with a 6' 10-Gauge 3-conductor Non-metallic Liquidtight A/C Whip purchased at my local Lowe's store. After running it for 30 minutes I felt the wiring and it didn't seem to be warm, so I have confidence it will not overheat. After using it a few times I find the thermostat, even though it doesn't have temperature markings, keeps a consistent comfortable temperature when I point the dial to the same place each time. Its near my step ladder so even though its high, its not really a problem. One other review complained about the thermostat, that it didn't have an off position. Mine does have a click feel when turning all the way down. Another review criticized that the heater won't come on when the temperature is below 50 degrees. That is false. The heating elements take time to heat up before the fan clicks on thereby creating a delay. The manufacturer explains that if the ambient air temperature is very low, that the fan may cycle on and off. Also, my suggestion would be to not connect it to a line thermostat ahead of the heater supply as this would disconnect power to the blower and the heating element at the same time. This heater is designed to expel residual heat after the heating elements are powered off so the fan needs to continue to run for a couple minutes. I'm not an electrical engineer but I would expect the added buildup of heat within the unit will shorten it's life. I very much like that it's made in the US. All in all, I am very happy with this heater and glad I bought it. I would recommend it to a friend.

I converted my attached two car garage into a wood working shop three years ago, I insulated the walls and ceiling and added some 220VAC circuits and a few more 110VAC (20 amp) outlets. What I have been struggling with is heating in the winter. I have been heating my New Hampshire workshop with a propane heater until the Christmas rush is over and then just call it a season until spring hits. The propane is just too intense, uses up too much oxygen, gives off too much CO2 and cannot be used while applying finishes. I tried some portable electric oil filled radiators that where inefficient, and cost about $70 for one month of intermittent use. After going back and forth and reading through several blogs and user reviews I decided on this electric heater with blower and thermostat. I ran a new dedicated 220VAC/30 amp circuit using 10/2 wire and instead of hard wiring to the heater I installed an electric dryer outlet to the ceiling and installed a dryer cord to the heater, all rated for 30 amps. I used the included lag bolts to attach the bracket to the ceiling and easily hung the heater centered about three feet away from the house wall. For a unit that is about a cubic foot in size it heats my 24'x24' shop with no problem, I can feel the warm air reaching all the way across the shop. The fan is quiet and runs without vibration, I cannot even tell when the heater runs from inside the house. I've had the unit for about a month, leaving is set on LO(which equals about 60 degrees on my unit) while I'm out of the shop, and easily heats the air up to 70 deg. in 30 minutes, however it does take quite a bit longer to heat the cast iron tools up to room temp. Even with the temps dropping to the teens and single digits overnight I have checked on the temps first thing in the morning, and it's a solid 60 deg.

PROS:
QUIET
COMFORTABLE WARMTH
AUTOMATIC THERMOSTAT/FAN CONTROL

CONS:
THE TEMP DIAL SHOULD SHOW DEGREES
NO REMOTE CONTROL (WITH THE UNIT MOUNTED TO THE CEILING IT CAN BE DIFFICULT TO ACCESS)
A minor issue, the access panel for installing the wiring does not fit well and the closure screw was driven in at an angle.
