Tubular heating elements and copper corrosion

With hard or chlorinated water the tubular heating elements can be protected with a magnesium anode

The company Gnali Bocia srl produces tubular heating elements that can be used in water heaters and boilers both open and pressurized.
The range available in the catalogue covers a wide variety of needs with heating powers ranging from 1000 to 3000 watts, normally functioning with 220 Volt single-phase power supply. However it is possible to have tubular heating elements which also function at 110 and 240 volts, standards different from the Italian ones.
For the connection of the power Faston Standard Female connectors are outlined to guarantee the universality and an optional connection for the magnesium anode protection can also be provided for the tubular heating elements.
This device is used in environments which are particularly capable of causing corrosion and wear on the heating elements. The products are always made with the best materials but despite this in order to prolong their life sometimes it is necessary to use this method for the protection of the tubular heating elements.
The temperature reached by the fluid during the heating is high, especially with water containing high quantities of minerals and therefore particularly hard, or on devices that treat water with large quantities of chlorine. In these cases the corrosion is shifted by inserting a sacrificial anode which corrodes instead of the copper.
In more complicated cases tubular heating elements made from stainless steel can also be used.
