What is a recirculating water line?

What is a recirculating water line?

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.

How does a hot water recirculating system work?

Connecting the recirculating system check valve to the system under the sink furthest away allows the system to provide quick hot water all along the line because the hot water is circulating throughout the house. An instant hot water recirculating system usually comes with everything you need to install it.

Where does the water go in the Recirculating loop?

These pumps are often located near the water heater, however, they can be anywhere in the loop. The pumps circulate water at low pressure and low speeds. Once again, there’s no need to have lots of water moving through the loop. It is just important that the water is hot near the fixtures.

How does a demand recirculating system work?

In a demand recirculating system, when the system is activated the pump starts recirculating cooled water that’s been sitting in the hot water line and sends it back to the water heater through the cold water line. When the water reaches a desired temperature a control turns off the pump.

Which is better recirculation or drain to waste irrigation?

Contrary to popular belief, recirculating hydroponic systems are not an “easier” solution as compared to drain-to-waste irrigation. These systems require special practices to provide optimal growing conditions. Knowledge and regular maintenance of all system components is required in order to prevent system failures.

What are the different types of recirculation systems?

There are two kinds of recirculation systems: closed or open. Cast-iron pumps are designed for closed systems. Closed systems are usually associated with hydronic heating and cooling applications like radiant floors and baseboard systems.

Why do you need a return line for hot water?

This loop keeps hot water going throughout the house so when a fixture is used hot water is right there because the water in the hot water pipe is kept warm at all times. If you have a dedicated return line, then this is a great system to use.
