It differs from cold-water plumbing by heating water before it is distributed throughout the structure. The primary components of a hot water plumbing system comprise the water heater, pipes, fittings and valves. The water heater is the primary element of a hot water plumbing system. It is the one that heats the water and keeps it in storage until it is required. The pipes transfer hot water from the water heater to the fixtures, such as faucets and showers. Valves are used to regulate the flow of hot water while fixtures are used to disperse hot water to different parts in the construction.
