I have my setup in a tin shed. The only tank with enough heat to fume much is the sealer. The dyes at 140* evaporate a bit but don't really fume. The anodize tank should not be getting that much heat. Yes heat is generated from running electricity through it but if it heats enough to fume like overcharging a battery something is wrong and you will not be growing any anodic coating. Being in a shed, you might have to use a glass aquarium heater to get you anodizing tank warm enough to anodize.
