I appreciate that you thought to ask me. But the truth is that even though I've kept Redfoot for several decades and I've observed and learned a lot, I have very little experience with heat or heaters for a tortoise. I've only used CHE in my outdoors houses. And before that I used Black incandescent bulbs. (And @Tom cured me of that a few years back)
Wow thats some heater. Im not sure about the noise factor maybe some of our more informed members can help us out on that one. The computer fan that I use is practically silent.Im not sure about using a ceramic heater with that high of a wattage in a small insulated area like a night box I would be afraid of it starting up and overheating by the time the thermostat kicks it off. I guess the only way to know is install it and check it with a heat gun before you put you tort out to use it. I have found out from trial and error that its hard to beat dog trainer Toms layout for nightboxes.I just sent this today so you are quick on the reply.
Would this heater work? cut and past that into amazon search bar.

You don't think the noise of this heater in the tight space would be irritating?
Thinking I would raise this heater off the ground if I do go with this.
