Mount whatever you buy in that big steel case. Fire the bast**d up. You'll get warm.

I have an infrared space heater that I’ve had for close to 10 years now, it still works as well as the day I got it.
They don’t make the model I have anymore, the only thing online I could find about it was from 2010 and it didn’t even have a picture.
Here is something similar though. It’s going for like $80 on Amazon (I think I paid closer to $100 for mine).

I use the space heater for my bedroom specifically but,I like it because it is portable so I can bring it into any room easily (mine has wheels and is pretty lightweight). It’s also cool cause it doesn’t get hot so there’s no burn or fire risk.

Oh, and to add, it makes my room HOTTTT and it stays that way for a while too after it shuts off.

Best heater you'll ever own.

I had one of those infrared box heater things (like this one). Kept my house to sweatshirt-level comfort when my central heat died one week. Area was bigger than your request, but also insulated living area.
