I just recently bought a tank, 8'x4'x2' and have some questions. Everything is up and working, and I know I'm probably going to sound dumb, but how to I heat the entire tank? I have my heating side, but does that water automatically run through to the tank? Do I have to run my pumps the entire time while heating? We do auto paint and body work, so we're not strangers to this world, but on this side of things I have no clue. Any help would be appreciated and tips on getting started.
