It is the one that heats the water and stores it until it is needed. The pipes carry hot water from the water heater to the fixtures, including showers and faucets. Valves are used to regulate the circulation of hot water, while fixtures are used to distribute hot water to different parts in the construction.

Storage tank water heaters store hot water in tanks until it is needed. Heat pump water heaters use electrical energy to transport heat to the air or ground to heat the water. Each type of hot water heater comes with its advantages and disadvantages. Tankless water heaters use less energy and have a longer lifespan however they are also more expensive. Tank water heaters for storage are less costly, but they have a shorter life span and are not as energy efficient.
