My father used to tell of when he was on searchlights in WW2. Their unit had a 'comedian' who thought it was hilarious to stagger back into the hut and piss on the hot pot-belly stove, then laugh about the complaints about the resultant steam.

They fixed him. The unit sparky wired the stove to a frightening voltage.

I've used it on my wellies/gumboots when fishing on VERY cold days.
