Honestly, I wouldn’t have a clue, but the best way to test this before putting it on a boiler is while it’s flat putting a flat thing of water that’s made of metal, preferably something similar to a boiler like copper or brass, maybe you can find a flat brass plate somewhere, so long as every part of the hot plate touches it, put water in it, and see if it boils the water and doesn’t burn out out (blow out)

If it’s an Amazon purchase, returns are pretty easy. If it isn’t Amazon, be weary on your tests. Do not fully trust this until you test it in some way mentioned above.

Perhaps someone else on the forum with more
Knowledge may be able to guide you? Don’t fully take my words of advice for gravy because there are more “seasoned” folks on here.

Just thought it’s a “possible” way of testing it first.
