Water heating is the process of raising the temperature of water for various uses, such as bathing, cooking, and cleaning. This can be achieved through different methods, including electric heaters, gas burners, and solar panels. The heated water is typically stored in a tank or delivered directly through plumbing systems. There are several types of water heaters, including tankless water heaters, which heat water on demand, and traditional storage water heaters, which keep a reservoir of hot water ready for use. Efficient water heating is essential for energy conservation and can significantly reduce utility bills when using modern technologies.
