An insulating board structure is placed into the chamber along at least a side portion of the housing. The insulating board structure contains heat within the housing for maintaining the metal in a molten state. A heater assembly is provided in a side of the furnace. The heater assembly is installed in the side of the furnace with a structural arrangement that protects against leakage of molten metal from the furnace interior to the furnace exterior.
