CAUSES OF COPPER CORROSION IN PLUMBING SYSTEMS …
www.fwr.orgThe following covers failures which can occur in both hot and cold domestic water systems, not closed central heating systems. Although failures of copper and brass fittings can occur in central heating systems, they are extremely rare as the dissolved oxygen content of the water is normally insufficient to cause corrosion.

gml.noaa.govone would find on oceans' surfaces. Water near the poles is very cold while water near the equator is very warm. The differences in temperature cause water to change physical states. Extremely low temperatures like those found at the poles cause water to freeze into a solid such as a polar icecap, a glacier, or an iceberg.
Safe management of industrial steam and hot water boilers
www.hse.gov.ukSafe management of industrial steam and hot water boilers Water treatment As with all systems where water is heated there will be a potential for scaling. This can lead to a loss of efficiency or, in extreme cases, premature failure of the boiler due to either scale build-up on the internal surfaces or debris from corrosion
