Looking for a 7500W garage heater that doesn't not NEED a remote to power on

I have a Dr. Heater DR-975 7500W garage heater. I wanted to be able to remotely power it up, so I had my electrician (who installed the heater originally) put in a DEWENWILS 800 Series Z-Wave Long Range switch, 40-Amp, in series with the heater.

Then I found out that the switch can turn power ON and OFF just fine (as expected), but the HEATER does not power ON when the switch is ON -- the heater requires a manual press of the "power" button of the accompanying remote to actually turn ON.

I've confirmed with Dr. Heater support that there is no way around this.

SO, query: does anyone know of a 7500W garage heater that powers ON when its mains are powered ON, no remote required?

Can you push the button on the heater instead of the remote? You could just add a button pusher device to turn on the heater after the 40-Amp switch turns on.

If it is only on the remote, you could also use an IR or RF blaster (depending on remote type) to turn on the heater.

I'm assuming you are not looking for either of those types of options.

You could also bypass that switch, if you were OK with opening the heater.

Also, what is up with the thermostat that is optional? The optional thermostat can turn it on and off, so why not use that terminal? If it was being controlled by a thermostat, nobody needs to push a button for it to come on. So a simple relay device on Terminal A could be used as a switch.

This also has a wired thermostat option. That's the angle I would take. Wire up a relay to the leads for the thermostat.

That will bring it on but what will keep the room from getting to hot?

You are somehow seeing this as different than the op's objective? A thermostat is a switch. On and off. We assume the OP wants on and off. I assume the relay goes off when the OP wants it to go off.

There are lots of ways to approach it. I would assume you could or would add a temp sensor somewhere in the mix of items.

You would then have a simple rule to turn the relay on and off by temp, or possibly even use one of the built-in thermostat controllers.

If you wanted to be simplistic you could just turn it on for a few minutes every hour. If you wanted to add complexity you could use outdoor temps to fine tune things.

I think you could even use a dumb thermostat (the old bimetallic style) in series with the relay that would control the temp. That would be a bit silly if you have a temp sensor in your hub ecosystem, but would work if you had nothing else.

You just get their thermostat and break the leg with a relay.

Internally there is a contactor.

Or you could wire a smart thermostat to a relay if that's what you wanted.

We have a Marley ceiling mounted heater in our garage. Simple dial thermostat on the heater. Looks like they have a 7500W version and is widely available. I put a Sinope heavy duty switch in line and it works as expected.

That looks like it would work, but Marley is VERY proud of their products, judging from their pricing!

Looks like Marley is made in the USA. And came with the house. Unfortunately it looks like Dr Heater doesn't publish CFM fan specs, so it's hard to see if that might be a performance difference. We don't use ours a whole lot, but the 5000W version keeps our 2 car detached and insulated garage at a reasonable temperature.
