Hot Water Plumbing Basics

Hot water plumbing refers to the plumbing system that distributes hot water to different parts of a building. It is different from cold water plumbing in that it involves heating water prior to it being distributed throughout the structure. The main components of a hot-water plumbing system include the pipes, water heaters, valves, and fixtures. Water heaters are the primary element of a hot water plumbing system. It is the one that heats the water and stores it until it is needed. The pipes transport the hot water from the heater to fixtures, such as faucets and showers. Valves are used to control the circulation of hot water, while fixtures are used to distribute hot water to various areas within the structure.

There are three main types of water heaters available on the market: tankless, storage tank, and heat pump water heaters. Tankless water heaters warm the water upon demand and don’t keep hot water in storage. Storage tank water heaters keep hot water in a tank until it is required. Heat pump water heaters make use of electricity to transfer heat from air or ground to warm the water. Each type of water heater is hot and has its advantages and disadvantages. Tankless water heaters are more efficient in energy use and have a longer lifespan however, they are more costly. Storage tank water heaters are less expensive but have a shorter lifespan and are less energy-efficient.
