Complete heater set for flange mounting on a 280 mm diameter flange. The heating element with thermostat can only be used for heating water in enamelled water heaters. For heaters with cathodic corrosion protection using magnesium or titanium anode, the heater shall be partially insulated from the tank wall by a resistive wire. As a result, the electrochemical potential difference between the copper elements and the carbon steel heating element in the water-filled tank is partially equalised. This has a great affect on the durability of the heating element and the magnesium anode.

The operating temperature range of the heating element is between 25 and 77°C (±5°C). The heating element has a built-in temperature regulator which protects the heating element from overheating (98°C (±8°C)). The heater is designed to operate at pressures up to 10 bar.

In the case of water heating systems in which the glycol (propylene- and ethylene glycol) dilution does not exceed 10%, the electrical heating element can be used, with the use of an inhibitor additive.
