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 then stored in a tank or delivered directly to faucets and appliances. There are several types of water heaters, including tankless, storage, and heat pump models. Each type has its own advantages and disadvantages, depending on factors like energy efficiency, cost, and space requirements. Proper maintenance of water heaters is essential for optimal performance and longevity.
