Now a word about installation. First and foremost, DO NOT believe another reviewer who said it needs a 25 AMP breaker. Not only is he wrong, but both common sense AND the manufacturer state that a 30 AMP circuit is required. That means BOTH 10 ga. wire AND a 30AMP breaker. And even then both the wire and breaker get warm after extended use. Not hot, but warm. Some people mentioned using a separate service switch. Instructions do not mention it and this unit CAN be turned off. I did install one. I used an Industrial 30 Amp double-pole switch, which looks and fits just like a standard light switch. Costs about $11 bucks, but cheap if you want a 240 volt switch. I also recommend using stranded wire which would go in some kind of conduit, either solid or flexible. 10 ga. solid wire is VERY difficult to work with especially if you decide to use a switch.
Now about the heat. Keep in mind that BTU is BTU. I got this mainly to try and replace my propane heaters because when it's really cold, they just pump too much moisture into the air for my uninsulated metal shop. Eventually it will be insulated. I have been using UP TO 70,000 BTU propane heaters to quickly heat up on cold days, so the 17,000+ BTU of this heater is not a fair comparison. But how well anything heats probably depends as much or more on the weather conditions and insulation. My shop is about 625 sq. ft. and even with 2 other 120 volt heaters, it would barely warm it up (14' peak roof also). So I saved the best until last. What better recommendation is there except that I ordered another one? Hopefully, 35,000 BTU will suffice for most conditions at least until I get it insulated. I will hook the second one up to be portable since I already have a heavy duty 10/4 cable.
I was fortunate to have the breaker panel next to where I mounted the heater, so installation was a breeze! I turn the thermostat down to 50F at night and turn it up to 70F about 30 minutes before I go out to work in the garage and it’s nice and warm when I go out there.
I purchased the Comfort Zone CZ220 for my garage that is 19'L x 14'W x 10'H at the peak. This heater is rated for anywhere from 600-1000 sq ft (depending on which site you go to). My garage being under those specs, this heater should be perfect.
Here is a list of things I used to wire up my heater properly into my sub panel in my garage:
-30A double pole breaker
-15' 10/2 NM wire (black/white/ground)
-15' flexible conduit
-1/2" water tight conduit connectors (x2) -one for sub panel & one for heater
I hardwired the heater to my panel routing it less than 5 feet from the panel. I first killed the power at the main in my house, then the sub main power and tested both phases to assure there was no power. I installed the 30A breaker in the panel and the black and white wires were connected to each pole on the 30A breaker and the ground to the ground bar in the panel. I then wired up the other end of the wires to the heater (which knockouts are available in multiple spots on the sides/rear of the access panel for your conduit) *white goes to L1 *black goes to L2 and the ground goes to the green ground screw. VERY simple hook-up even for the novice do-it-yourselfer. Dont be confused about which wire goes to L1 or L2 because it really doesnt matter. Just make sure it is properly grounded.
Now, I'm all hooked up and ready to turn it on.
I flip the breaker and voila....fan begins blowing and heat begins blowing. It runs very quiet and seems very well made. No buzzing/humming/rattling etc. DO NOT BE FOOLED BY THE SIZE-this thing cranks! I can feel the heat blowing from over 15' away which is amazing for this size and how quiet it is. It was 24 degrees F in Michigan the day I installed it and it took about an hour or a bit more to bring it from a frigid cold to approx 65 deg F. I came back out and was impressed with how warm it had gotten in such a short time. I switched it from 5000W to 4000W now that it is up to a decent temp in the garage and it keeps my garage a constant & toasty 70 Deg F with ease. The thermostat is pretty easy to set. Just get the room to the temp you want, then dial it back til it shuts off. There is no "temp" setting in degrees but is labeled with a dial from low-high The cycle times are different from application to application I'm sure, but in my application I have a 1 car garage that is now insulated top to bottom with R13 and partially drywalled. The insulation around the big door is terrible. With all of that in consideration this heater is more than enough for my application. On a cold, below freezing day my cycle times are short with 9 min ON/17 min OFF. You cant beat the cost/quality/quiet/etc for the price. I got mine delivered to my door for less than 150 plus add 35 or so in extras needed to hook it up. If you are budget minded and looking for a great heater that is easy to hook up and very cost effective....look no further. Now that I have witnessed what this heater is capable of, I have no doubts about its claims on square footage it can heat. After doing the math I am guesstimating that it will cost approx 70 a month to run this heater but the truth will be when I get my bill. I am 2 weeks into the month as of this review, so I will update with power consumption once it is calculated accurately.
The unit ran flawlessly through the 2015 winter. The Temps are now getting down to where I need to run the unit and so far so good in winter 2016. I set it so not comes on at 65ish degrees and last night it got down to 30° and it maintained 65°, cycling on and off as it should. I love this heater and so does my dog.
