Mild Steel TBH - 100 Resistance Heating Machines

The electric resistance heating is the least expensive way to change electricity into heat in any metallic object. In a furnace, the entire furnace has to be heated, the elements have to be heated, which in-turn many times heat a muffle which in turn heats the part in which heat is desired. Resistance heating is a more direct method of producing heat only in the object in which heat is needed.
