Hot water heater recirculating pump diagram.

Any cold water in the recirculation line is returned to the heater. There are two main components to an effective hot water recirculating system.

The recirculating pump installed on the hot water discharge line of your home s water heater and the sensor valve installed on the supply lines of a faucet at the farthest distance from the water heater.

A hot water recirculating system can give you instant hot water but you must mind some important safety tips. With this option an additional pipe that is designated for hot water is installed in your home s plumbing. A pump at the water heater moves hot water through the recirculation line.

In a traditional hot water recirculating system there is a dedicated return line for the hot water pipes which runs from the furthest bathroom or fixture back to the water heater. Near the water heater area a recirculating pump pulls the water from the furthest fixture back into the water heater creating a loop. The pumps circulate water at low pressure and low speeds. The recirculating pump keeps hot water moving through your home s hot water pipes at all times on demand or set for specific hours via a timer different from a water heater timer.

A check valve must be installed in the line to ensure hot water. A recirculation line is a separate water pipe that runs off the hot water line from the farthest plumbing fixture back to the water heater. If the hot water is not used it simply returns back to the tank.
