Difference between hot water flow and cold water flow? ?

The main difference between hot water flow and cold water flow is the temperature of the water. Hot water flow refers to the movement of water that has been heated to a higher temperature, typically for use in activities such as bathing, cooking, or cleaning. Cold water flow, on the other hand, refers to the movement of water that is at a lower temperature and is typically used for drinking, washing hands, or other purposes where hot water is not necessary. Additionally, hot water flow may be controlled by a separate hot water heater or boiler system, while cold water flow is typically supplied directly from a municipal water source.
