Figure 4 shows how it works:
- Step 1: Turn on any hot water faucet in the house for 1 second and then turn it off.
- Step 2: The circulation pump is activated
- Step 3: Cool water from the hot line is circulated back to the water heater through the cold water line
- Step 4: Enjoy hot water without wasting it down the drain.

How much does it cost to recirculate hot water?

How does a hot water recirculating system work?
A hot water recirculation system is a plumbing system that moves hot water to fixtures quickly without waiting for the water to get hot. Rather than relying on low water pressure, common in most water lines, recirculating systems rapidly move water from a water heater to the fixtures.

What's the best way to recirculate hot water?
The most efficient “traditional” recirculation method would use a combination of both a temperature sensor and a timer to activate the system. The temperature sensor monitors the hot-water line: Once the preset temperature is reached, the pump automatically shuts off.
How does a hot water recirculation pump work?
The result is a continuous loop of hot water. If the recirculation pump system is activated with a sensor or a timer, the pump kicks on to match your hot-water usage needs and, again, shuts off once the preset temperature in the return line is reached. Some hot-water recirculation pumps are built into the water heater itself.
Is there a hot water recirculating system under the sink?
This type of under-the-sink hot water recirculating pump will require power under your sink to operate. This type of recirculating system is similar to the instant recirculating system, but rather than running constantly or at preset timed intervals, it requires the user to activate the pump when hot water is needed.
When to use hot water recirculating system in shower?
This means that as soon as you open a faucet or turn on a shower, warm water is already present in those pipes, so you don't need to waste water down the draining waiting for the water to heat up.
