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 in that it involves heating water before it is distributed throughout the building. The major elements of a hot water plumbing system include the pipes, water heaters, fittings and valves. Water heaters are the most critical component of a hot water plumbing system. It heats the water and keeps it in storage until it is required. The pipes carry warm water that is heated from the water heater to the fixtures, such as faucets and showers. Valves are used to control the circulation of hot water while fixtures serve to distribute hot water to various areas within the structure.

Different types of hot Water Heaters

There are three main types that hot water heaters are on the market that include tankless, storage tanks, and heat pump water heaters. Tankless water heaters warm the water upon demand and don’t conserve hot water. Storage tank water heaters store hot water in tanks until they require. Heat pump water heaters make use of electricity to transfer heat from air or ground to warm the water. Every type of hot water heater comes with its advantages and disadvantages. Tankless water heaters use less energy and have a longer life however, they are more costly. Storage tank water heaters are less costly, but they are less durable and aren’t as efficient in energy use.
