Question on installing Comfort Zone CZ220 Heater.

Hi,
I have this heater I want to install in my attached garage where Main Power Panel is. It’s 5000W, draws 21A. Plan is to install Overhead, back wall, center. This will of course require a belly crawl through Insulation in the overhead from panel to back wall.

The heater has 2 Terminals for L1 and L2 and a point to secure the bare ground wire.

Question: Aside from the trivial cost savings by Manufacture, why is there not a 3rd Terminal for a dedicated Return? It seems this would not meet Code due to lack of grounding for Safety. Just asking.

Plan is to use more expensive 10/3 in lieu of 10/2 and err on side of safety.

If anyone has experience with this CZ220, I’d appreciate your feedback.

Thanks
Leaky

A dedicated return? You mean a neutral? You are confused

240v utilization equipment does not have a neutral because it doesnt need it. A neutral is for 120v voltage.

I do not understand your last sentence. The heater has a grounding terminal.

Also, you dont need 10/3 which is 2 hots neutral and ground. Get 10/2.

It has no need for a neutral. The ground is already just for safety. It would function fine without the ground unless it develops a short to the metal case.

10/3 is a waste unless you like parking extra wire in a wall. Why not leaving an unopened roll in the attic or something. It would do the same amount of good.

Ok. Got it. Sorry I asked.

The more I read the original post the more I think the op does not understand how split phase AC works. Never to late to learn.

Power will flow from L1 to L2 without any need for a neutral. The neutral is only used if you want 120v

I just installed this heater in my garage a couple months ago. I used 10/2 (orange) wire plus a 30 amp 220 breaker. Two wires are hot plus a ground. Works great.

Because I tapped my heater off the 50 AMP circuit feeding the receptacle I plug my arc welder into. I protect the cable, and control the heater, with a 30 AMP fused disconnect.

When I want heat I push the handle UP when I am comfortable I pull it down.

Before the Flame Cannons are loaded, my tap conductors are less than ten feet long.
