  • Water heating - Wikipedia

    2021-9-6 · Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated to steam have many uses.. Domestically, water is traditionally heated in vessels known as water heaters, kettles, cauldrons, pots, or coppers.
