Will the acid react with the copper element ?
I would heat the tank in some sort of double boiler bath arrangement with anti freeze chucked in the heating water
A 200 ltr steel drum cut lengthways will give you a cheap tank with a screw fitting for the element. I would cut it so that the part you use is a bit more than half the drum - more a horse shoe shape than a half circle.

Drums are made out of sheet iron = ferrous, acidic immersion will give the acid breakfast.

Not what I wrote, 'double boiler' bath. Which means put the acid tank inside a larger heating tank (half drum) filled with water and anti freeze where the heat is transferred from the liquid in the heating tank through the wall of the acid bath tank. Cant boil over and any spillage is captured in the outer tank. Like a little pot sitting inside a bigger one as an example.
