· If an inert anode is used there is no participation in the chemical reaction and no heat generated into the bath. To keep the same pot thermal balance the missing heat has to be provided through external voltage. As a rule of thumb the heat generated by the burning of the anodes is equal to 1 Volt in electrical terms.
