Reupholster radiator in aluminum = adhesive that withstands heat?

[RilleRock]

Hello,

I have a radiator in the entrance that has been wallpapered d^_^b
After I started removing the wallpaper and glue, I realized that the radiator had a dent, and the first thought of repainting it went out the window.

So I thought I could cover it with a nice new sheet metal that a metalworker has bent to fit.
Ideally, there should be no visible screws.
Is there any adhesive for metal-to-metal that can withstand the heat?

Why spend so much work and money (sheet metal work and metal are not free) on an old radiator? If you involve a sheet metal worker in the project, it becomes cheaper to buy a new radiator.

Not to say that sheet metal workers are more expensive than other craftsmen, but in this context, their hourly rate (including VAT) exceeds the cost of a new radiator.

Can't help but be curious: Why bother with an old radiator that's not even from the turn of the century?

Cutting and bending a sheet twice should be cheaper than a new radiator?
That is, I call them and provide dimensions and pick it up when it's ready.

I have a brand-new radiator standing in the garage that I bought from an HVAC wholesaler. However, an acquaintance who is a plumber said that my existing super old aluminum radiator heats up to one and a half times more than the new one. And that's reason enough for me since I can save a lot of energy.

Does it make more sense now?

This recycling element is the only one I have and keeps the whole house warm except when it's the coldest. Switching to an element that is not as efficient, so I need to use more electric heaters, is foolish. In the other rooms, there are electric heaters and, in addition, I have an LLVP. Thus, I need to maximize the heat output as much as possible so I only need to rely on electric heating when it's the coldest.

Yes, there is heat-resistant glue. It is used, among other things, for gluing heat sinks to semiconductor components in computers, etc. Go to the hardware store and ask; I recall seeing it at clas ohlsson too. However, keep in mind that you alter the heat conductivity of the element when you apply an extra layer of metal. I have no idea what that would entail, but it feels like it would be worse. Maybe you should consider a radiator cover instead?

They will be open at the top and half a mm of metal around shouldn't deteriorate it that much.
But yes, I might be wrong.
I will test with metal since it only costs around 300 kr then we'll see.
Do you mean a wooden radiator cover?
That, if anything, must deteriorate the heat conductivity?
Looked around a bit and many have said just that.
But sure, many of them are nice-looking.
