Abstract: | Corrosion in warm water heating systems Corrosion in warm water heating systems is due to the presence of oxygen. In open systems oxygen can penetrate into the warm water by expansion vessels, at high through-puts because of unfavorable fitting connections of pumps and as a consequence of malfunctioning. Corrosion in closed systems occurs only in cases of temporary penetration of oxygen followed by air cushion formation. In view of the fact that the formation of protective surface layers from water constituents is able to reduce oxygen corrosion it is recommended to apply water softening only in such cases where the inhibition of incrustation becomes a necessity. |
