Tankless water heater
This diagram illustrates the plumbing system of a tankless water heater with a recirculation loop.
Cold water enters through the blue-labeled inlet, where it is heated on demand as it flows through the unit.
The heated water is then sent to the hot outlet, supplying warm water to fixtures such as the sink.
The recirculation loop, controlled by a dedicated valve, ensures that hot water remains readily available by continuously cycling warm water through the system.
This setup reduces water wastage by eliminating long wait times for hot water at the faucet.
The inclusion of mixing valves helps regulate temperature, ensuring user safety.
Overall, this system improves efficiency and convenience, making it a practical solution for modern plumbing applications.
