enamelled. A flange is welded onto the bottom of the tanks with a flange lid screwed to it.
A sealing ring is inserted between the flange lid and the flange. Thermowells for placing a heating element,
thermostat sensors and safety fuses are located in tone flange lid, and the safety fuses and the second
flange lids are without thermowells. An anode rod is mounted onto the M8 nut. Electric wiring is placed
