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.
