What Is a Hot Water Heater Recirculation Pump?

A Hot Water Heater Recirculation Pump is a plumbing device designed to circulate hot water through your pipes either constantly or on a demand basis. This keeps water from going cold in the line, thereby providing you with immediate access to hot water and saving water-wasting gallons.

How the Plumbing Recirculation System Works

A plumbing recirculation system functions by creating a loop of water flow from the water heater to fixtures and back. Here's how:

Water that has cooled while sitting in the pipes is sent back to the heater.

This loop ensures hot water is always near the point of use.

Some systems include timers or motion sensors to activate the pump only when needed.
