Water heating systems are devices designed to heat water for various uses, such as bathing, cooking, and cleaning. They can be powered by different energy sources, including electricity, natural gas, propane, or solar energy. Common types of water heaters include tankless, storage tank, and heat pump systems, each with its own advantages and efficiency levels. These systems work by transferring heat to water, either by heating it directly or by using a storage tank to keep hot water ready for use. Regular maintenance is essential to ensure optimal performance and longevity, helping to prevent issues like sediment buildup and leaks.
