1.3 DESIGN AND GENERAL HEATER DIMENSIONS
The heater tank is made of a steel plate and tested by 0.9 MPa overpressure. The inside of the receptacle is
enamelled. A flange is welded onto the bottom of the tank 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 the flange lid. An anode rod is mounted onto the M8 nut. Electric
wiring is placed underneath the plastic removable cover. Description of basic parts of the heater – Figure 1.
