Hot and Cold water systems in buildings are used for washing, cooking, cleaning and other specialized functions.
Cold water for buildings is also known as potable water.
Non-potable is supplied in some countries; this is not for drinking or cooking.
Hot water is used for washing and cooking. The temperature required is about 45oC. Water is usually generated at a higher temperature (55oC to 65oC) in a vessel and mixed with cold water at mixing taps or mixing valves.
