The term "hot water plumbing" refers to the system that supplies hot water to various areas of a building. It differs from cold water plumbing by heating water before it is distributed throughout the building. The main elements of a hot water plumbing system are the water heater, pipes, fixtures, and valves. A water heater can be described as the most critical element of a hot water plumbing system. It heats the water and stores it until it is needed. The pipes carry boiling hot water out of the water heater to fixtures, like showers and faucets. Valves are used to regulate how hot water flows, while fixtures serve to distribute hot water to different parts within the structure.
