It heats the water and stores it until it is needed. The pipes transport the warm water that is heated from the water heater to fixtures, like showers and faucets. Valves control the circulation of hot water while fixtures are used to distribute hot water to various areas in the construction.

Tankless water heaters are more energy-efficient and last longer however they are also more costly.
