How to Install an Electric Garage Heater: Comfort Zone Model CZ220

[@PainterD54]

I installed one in my three stall shop a couple years ago and it works great! If it's in the single digits outside I will use my 80,000 forced air diesel heater for about 15 minute to bring up temp to working conditions (65 -70) before it shuts down. Then the electric heater takes over and maintains the temp all day. It took me all of 15 minutes to install and hard wire it to the fuze panel. And the good part is my electric bill doesn't seem to go up much!

[@cgreenfield6655]

I just bought this exact heater. I was surprised at how well it has warmed up my 24x22 (10ft ceiling) garage.. I need to install a thermostat though.

[@RobDucharme]

@Jimi Bmore Fucking seriously? You think I can't figure out a knob? "Comfort Zone" was the name of mine. IT. DIDN'T. WORK. And before you run your mouth again, know the difference between the practicality of a knob thermostat on the unit hanging from the ceiling and one mounted on the wall that can be controlled remotely (and is within reach), as was going to be the case (and certainly is with what I have now). I've since moved on to a competent GAS unit that heats the garage in a fraction of the time and costs way less to run.

[@clifwilks]

Just installed this exact heater yesterday (per recommendations from KZbin) easy install...already had the 30 amp breaker in my breaker panel so easy peasy...we'll see how it does today.....thanks for the video.

[@keithharrington8715]

2 style points : 1) connect your wires ground first, then neutral (white) second, then any hots. This is the safest way. 2) always do the panel connections last.....it is hard to accidentally energize something that is not plugged in or connected to power.

[@Charlie1993ohio]

ive had this heater in garage for 3 years I got it for Christmas been too scared to mess with my panel I think ill do all the beginning part

[@charlesbeall2589]

I'm with ya' Charlie. I've been buying a heater like this for the past 20 years! Garage is well insulated enough, that a small 110 volt heater brings it up to 50 degrees when it's 30 outside. One like this shouldn't have to run full blast for long. Have a blessed Christmas!

[@halleyeve8138]

Thank you for the great video. Your instructions were perfect!

[@TheNezfamily]

garage insulated and still takes an hour to get to 50.....went with propane ventless and that did the trick

From the main box to where im going to keep the heater. Is 80ft. Do i need to use a different wire. Its a 5000 unit. Thank you.

I would have used 10/2 armored cable to power this; might hold up better over time and protect the conductors better.

[@mustangdemon87]

It's up above the joists so no need to. Not to mention he would have to change to a metal box for proper grounding. 😉

[@Jk-uo9oh]

Will be installing one of these heaters (different brand, but looks the same) in tomorrow. One question regarding heater that I have that cannot be found in poorly written manual. When I am not using the heater, is it technically still "on'. No where in the manual or on the unit does it show that you can turn it off. In watching another video, that guy just flipped his circuit breaker off when not in use for an extended period of time. Thanks

[@TheOriginalMechanic]

Mine is certainly not on when the dial is fully counterclockwise. By that I mean there is no heat and no fan. The small red light is on but that's it. I never saw any need to turn the breaker off but certainly that is an option in the off-season.

[@Mike-ht1ou]

Thanks for the reply, good to know that the heater will be off when turned fully counterclockwise. I was debating on installing a double pole thermostat to turn off power when not using.

[@ATappin]

How does the automatic thermostat work? The instructions say to turn it on high and when it reaches the desired temp to turn it off and it will switch on and off to maintain that temp. Doesnt seem to be working

[@TheOriginalMechanic]

I'm not sure. When I've used mine it is always quite cold weather and it runs like yours, continuously. I think the temperature control of these units is quite weak and a remote settable conventional thermostat would be better control solution.

[@Vault20boy]

I bought the 10,000 watt heater and need help with the 50amp 6wire. The wires have a Red, White, Grey and the cooper wire. But my heater is like yours.. only have 3 connections.. not sure what to do with the white wire.. if its neutral or if its power

[@BradyHommel]

I have the same exact issue. did you resolve this?? Do I just tie the white and copper wire together in both the panel box and heater??

What is the warmest you had it in the garage like on a 20 degree outside day or night?

[@willpulera7303]

"minimum height" is 6'-4" so I'm curious why you felt the need to hang it as low as possible instead of hanging directly from rafters?

[@TheOriginalMechanic]

I hung it that way so I can get at the controls without a ladder. It doesn't come with a remote.

[@futbol1972]

Now iam wondering if I should get just one of this heaters or a window ac/heater for my fully insulated 3 car garage? If I get just a heater then I have to worry about getting something to cool it in the summer. I just don't know which way will be the way to go, two separate units one for the summer and one for winter or just find a unit that has both in it ac and heating? Garage is about 660sq ft and 8ft ceiling night, fullybinsulated even garage doors. Live in Clovis ca with a climate zone of 9b

10/3 wire will not work?

[@Ozicool]

10/3 work perfect

[@darrylt1031]

does it matter which wire (black or white) goes to which terminal inside the heater?....also, you didn't mention to use a 220-240v circuit breaker.

[@keithharrington8715]

No, not in 240vac. The wires are physically the same size and can carry the same amount of amps.I But Remember, the electrical guys color code the wires for an understanding of what that specific wire does. They leave a white wire white if it is connected to the neutral bar in the panel. If that white wire is connected to a breaker, they normally "colorize" it red, blue, or black with tape or marker. Hope that helps.

[@milagrossmith4891]

One I'm a little confused. Don't you have to install a wall outlet for this? He did not plug it in the wall

[@TheOriginalMechanic]

A wall outlet isn't necessary unless you want the heater to be mobile. I'm using it in this one place in this one garage so I hardwired it into a dedicated 220V breaker in a 200Amp household breaker box. If you want to move it around to different buildings, sure then install 220V outlets.

[@BIG_DRU]

Is it still doing the job today?

[@TheOriginalMechanic]

Sure still works. The only issue is a burned out power on light.

[@Pmason718]

I just bought this heater and now I’m afraid I can’t use it after reading the installation manual. My garage ceiling height is 6 1/2 feet high and if I mount this to the ceiling my minimum distance to the floor will be 5 1/2 instead of 6ft, anyone know if this will be a real issue for some reason?

It’s all relative to safety of course. Keep any flammable/combustibles away from that area

[@roberthastings6050]

Do you have any suggestions on how to install a remote thermostat on this model / Thanks !

[@TheOriginalMechanic]

It's going to have to be in the control circuit in series with the temperature dial. You'll have to open that circuit and wire it in there.

[@joeoconnell5706]

I have this exact model and the instructions say that the minimum clearance from the bottom of the unit to the floor is 8 ft, not 6’4”. Do your instructions say different?

Yeah mine was 6'4". They must have changed it. Maybe some really tall people hit their heads and complained.

[@jz497]

Great video straight forward 👍

[@futbol1972]

Hello I been looking at many youtube videos about this heaer and many people said their electricity went up quiet a bit:( If I buy this electric heater I will be only using it when I play pool in my garage which is once or 2x a month for about 6 or 7 hours. Since I have natural gas I wanted to install a natural gas heater but this sounds expensive to tap into the gas line or run a gas line to garage. However I think on the long run it will be cheaper that the electric heater??? Some people on you tube said it went up to $100 dollars a month others said about $30 or $40?? Anyways I will be installing a 240V outlet into my garage since I will also be getting a used electric car and need to charge it. So if I decide to get this electric heater I will already have an outlet for it. On the videos I see people installing the electric heater high in the ceiling usually on the corner. If i get electric heater can I just use an extension cord to plug it in or iwill it be better if I just install 240V outlet close to ceiling where heater will be?

[@TheOriginalMechanic]

I didn't notice much with the electric bill. I only use mine intermittently when I do a job in the garage though. i wouldn't use an extension cord in a 240V high current circuit due to risk of overheating. Maybe a two socket 240 volt outlet?

[@futbol1972]

@@TheOriginalMechanic oh cool I did not know they had a 2 socket 240v outlet? Well, in this case when charging car I have to maybe get on stool or something everythime I wanna charge my car. Or maybe I can live car charger pluged in all the time and just coil it and hung it up on wall so I don't have to use a ladder or anything to get up there to plug it in all the time. My ceilings are only 8ft high but still.

[@josephvance8900]

Your bill will go up a lot if tou use it everyday. I have one in my shop and when it gets below freezing outside i have to let it run all night because my chemicals and pressure washers will freeze. My electric bill for my shop during the summer spring and fall is only 45-65 dollars a month. When I use this heater it jumps up to 120-150..The highest it ever hit 230 dollars. But that was when we had a an extremely cold spell and ice storm. Plus I was also using a small heater fan in my bathroom to keep pipes from freezing.

[@donniefisk2252]

I know this is hardwired in but is it possible to use 240 v plug and outlet ? Thanks

[@TheOriginalMechanic]

Sure, as long as the breaker in the circuit is able to handle the load. A clothes dryer is an example of a corded 240V appliance.

[@donniefisk2252]

@@TheOriginalMechanic thank you so much . So the 240 I have ran is 10/3 Romex. Not 10/2 . Would you recommend just running a new piece of 10/2 from the heater to the box instead of the 10/3 Romex? I initially wired the outlet with the Romex . Safety comes first though . I appreciate the reply and help.

I bought a 15000w heater for my pole barn. I used your video to help install, but my breaker blew. Can the 10/2 romex and a 2 pole 30 amp breaker?

That heater is three times the wattage of my install. So you to step up both the wire and breaker. The manufacturer should have a recommendation.

[@richardgast7824]

I used 10ga SO to make a plug wire when I opened it this year after running it last winter the black side of the terminal block had over heated and partially melted. Any idea what may have caused this.

[@TheOriginalMechanic]

That gauge of cord should be fine. I would check the tightness of the connection at the terminal block. It needs to be very tight.

[@keithharrington8715]

@@TheOriginalMechanic remember that every nut and bolt has a torque specification. I do not know that spec off hand. But, it is kinda like a car tire lug...."ass-ton" should be good, but the ones on my truck were torqued to 75 ft-lbs. Yes, a big deal for my tire guy. A loose connection on wires allows heating and problems.

[@derekw40]

Do you feel like the temp increase is adequate? Or below expectations?

[@TheOriginalMechanic]

It's well worth it to me under most conditions. Although in periods of extreme cold we can get here in the north it will not get the garage t-shirt warm. Maybe 40 degrees when it's below zero outside. Still, I can work in that.

[@kissfreak333]

I have the 7500W version, would i need a different sized breaker or thicker wire?

[@TheOriginalMechanic]

If the instructions don't cover that, you will need the full load amps at high power setting to determine both the breaker and wire required.

[@DanielBrown3]

The instructions for the 7500 watt recommend 8 gauge wire and a 50 amp breaker

[@Shoobylives]

My garage already has a dedicated 240 volt outlet for my ESAB MIG welder, on a 50 amp breaker. Is there any reason I cannot wire the heater to an appropropriate plug?

[@TheOriginalMechanic]

Yes it would work. However, your breaker is over-sized for this 22 amp heater. A 30A breaker is the appropriate size.

[@russellsgarage415]

I had the same question. I bought a 40ft welding extension cord and cut 10 foot off to use as a power cord. It works great, but as you pointed out, the breaker would be oversized. Biggest concern would be a fire of course. I plan to unplug it when I’m not in the garage.

[@Beecharmer799]

The breaker at the end isn’t the same as the one in the beginning

I commend your observation skills. The GE breaker I bought first did not physically fit in my breaker box. I wound up using a Square D breaker. Both were 30A breakers.
