I currently own two of these heaters and am buying a third in the very near future for a small art studio for my wife. The two heaters I already have, have been in my 36 x 20 shop with 10' ceilings. I rarely use both at the same time unless its super cold I have had both for 12 years with no issues. One keeps the shop at 65 degrees with no issues but when I want to kick it up to 72 - 75 one will do it but I will turn the second one on to make it easier so they run less. Would recommend this to everyone. Not the cheapest little heater on here but its true you get what you pay for.

I use this unit to heat a Georgia garage work space of about 530 SF with 14' ceiling (volume ~7400 cu-ft). Space has minimally insulated walls, ceiling and double overhead door.
One Marley Fahrenheat Ceiling-Mount 5000 Watt Electric Heater, Model# FUH5-4 (mounted 12' AFF) is able to maintain this space at 68F with an outside air temp of <20F while running <10hr per day.
I modified it for remote thermostat control, exactly as recommended in review above by JohnHMA, (Honeywell R841C-1169 Electric Heat Relay and a Honeywell Digital T-stat (mounted 5' AFF)) with addition of a Hour-meter that records actual heating element run time. I installed it in November 2013. Its now the end of June 2014 and it has accumulated a total flawless run time of <800 hours.
At a cost of about 10 cents per kWh, this heater costs about $0.50/hour to run. This works out to about $67/month for the cold months it was heating, Well worth it to have a comfortable winter work space.
John, thanks for the tip!

Best product at an affordable price.
Reviewed several heaters online and looked at complaints. Talked to an electrician who will be installing the same and received favorable results from him. He recommended this product as an easy model to install and that the lifetime of the product was also favorable. I can give a better review when winter comes again and it has been installed. I bought it at the end of winter because of recommendations and the sale price.

Very Surprised How Strong It Is
I have a 1100 sq ft. garage with 9.5 ft. ceilings. The winter of 2014 was COLD in New Hampshire (went for a month without going above freezing). When I ran the numbers it was marginable that I needed 3 of these heaters, I brought 2 to save the money. I figured if they couldn't handle it I could add the third one. I CAN'T believe how well they work for the money. No problem keeping the shop at 68 degrees. I am very happy with the purchase, even buying two of these heaters it is still half the price of a oil or propane furnace. I had heat in an afternoon. Just connect the wires. No chinney, no ductwork, and no plumbing. Unless you are heating finished living space do yourself a favor and go with this heater.

Awesome Awesome Heater
This heater is what every antique car garage hobbyist is searching for to deal with the 2014 Arctic Vortex Winter Storms. Set controls on mid setting and waited about two hours to test temperature in my un-insulated garage, the heater warm my two garage to 65 degrees and was cycling off and on by the thermostat. The outside temperature was 22 degrees and falling . Don't under estimate this heater - thinking it is small in size so it must be inadequate. It's worth every penny. And that is how the cow ate the cabbage. Jack

I bought this heater for my garage so I could work on car in the winter and it works great. Easy to install, you can change air flow direction easily and temperature seems to stay constant at temperature setting.

Installed 2 -- Results detailed
I installed two of these heaters—one in my 200 sq ft shop and one in my 500 sq ft garage. For each unit I installed a double pole, single throw, wall switch rated at 30 amps. The heater does have an internal thermostat with a positive off setting (you can feel it click off), but I prefer also having the remote disconnects in addition to the dedicated 30-amp breakers for each. I used Romex 10-2 w/ground wiring (which is rated for 30 amps) where the walls are or will be enclosed, and then from the walls to the heaters I used flex conduit so no sheaved wiring will be left exposed. (4-ft flexible conduit whips with 10 gauge stranded wire are available at the big box stores, plus they have the 30 amp double pole switches that are needed to interrupt both legs of the 240 VAC supply.)
I am puzzled by some of the reviews. One dissatisfied reviewer mentioned that the yellow light stays on so he knows that the unit is receiving power…but there is no yellow light on the 2 units that I have. There is only a single red alarm light that indicates when an overheated condition has occurred, so normally this light would never come on. Another reviewer mentioned an off-balance fan and noisy operation. For the record, neither of my units has fan problems, and although you can certainly hear the fans when operating, the noise level is what you would expect…not objectionable at all for an industrial type heater. And then there was a reviewer who said that the unit doesn’t really have a thermostat, but a timer with the option of choosing low to high heat settings. A timer??? Not on mine. I am left wondering if people have accidentally reviewed the wrong heater. At any rate, something isn’t right. Two back-to-back negative reviews almost seem like they were written by the same dissatisfied person.
My 200 sq ft insulated shop heats up from 30 degrees to 56 degrees within in 45 minutes. My 500 sq ft partially insulated garage (one wall is yet to be insulated) heats up from 30 degrees to 50 degrees in 45 minutes. Once the temperature that I want has been reached, the heaters cycle on infrequently as holding a temperature is considerably easier than first reaching one. Here are specific test results:
Starting temperature was 30 degrees for each.
@ 10 minutes: Shop = 39 degrees / Garage = 34 degrees
@ 15 minutes: Shop = 42 degrees / Garage = 39 degrees
@ 20 minutes: Shop = 45 degrees / Garage = 41 degrees
@ 25 minutes: Shop = 47 degrees / Garage = 45 degrees
@ 30 minutes: Shop = 50 degrees / Garage = 46 degrees
@ 35 minutes: Shop = 52 degrees / Garage = 48 degrees
@ 40 minutes: Shop = 54 degrees / Garage = 49 degrees
@ 45 minutes: Shop = 56 degrees / Garage = 50 degrees
Test halted—temperatures still rising.
As others have stated, a remote thermostat would provide improved performance, but then you invite additional wiring and more places for things to go wrong and for people to make mistakes. The internal thermostat should be considered a necessary compromise, and it functions well enough for satisfactory operation. Also, the fan initiates operation AFTER the coils come up to temperature (reduces the chill effect), and the fan has to continue operation for a while AFTER the coils no longer are receiving power and are cooling down. Here is where you don’t want to rely on a remote on/off switch or typical thermostat since cutting power to the unit when the coils are still energized prevents them from being properly cooled down by the fan. You should normally turn power off to the unit only when assured that the coils do not require cooling.
If these heaters prove reliable after more extended use I will be more than satisfied with them. It sure beats having a propane or kerosene heater to refuel with their related odors and increased risks of fire, not to mention potential carbon monoxide issues. Incidentally, a 1500 watt 120 VAC heater cannot begin to compare with the heat generated by these efficient 5,000 watt heaters. I used 3 nearly identical 5,000 watt Dayton heaters at a remote site in Alaska for 5 years with one failure—and that was for one of the heaters that had been in use an unknown number of years prior. It wouldn’t surprise me if the same manufacturer makes these Fahrenheat heaters. If I had to do this all over again, I would make the exact same choice.
By the way, I tried to upload 2 photos showing these 2 installations, but the server would not allow this even after 4 tries. The photos met all the required guidelines.

bringing the heat
This heater did an excellent job of replacing OEM.
And it used as an addition at another location where it proved easy to install and effective.
