Rinnai uses the cold water line as a recirculating loop to save the cost of adding more plumbing
We’ve all been frustrated waiting for hot water to actually get hot. In colder climates—and if the water has a long way to go to your water heater—you may wait more than for a minute or two for hot water to actually reach your sink or your shower.
This results in a lot of wasted water and money right down the drain. The good news Rinnai has the solution called recirculation, and here's how it works.
An internal or an external pump allows your Rinnai tankless water heater to push warm water through your plumbing lines at scheduled intervals or on demand, by pushing a button or using motion sensors at the faucet.
In the video, recirculation is accomplished with a dedicated return line.
That’s great if your home has one but many homes don’t have a built in return line. Adding one can be really pricey and time consuming. But Rinnai has a unique and effective solution for this varied problem.
Rinnai’s ThermaCirc 360™ technology and its SE+ Series is equipped with a thermal bypass valve, allowing water already in the system to recirculate.
It flows through the install valve and recirculates back to the tankless water heater through the cold water line.
ThermaCirc 360 gets you faster hot water at your faucet regardless of your plumbing configuration.
How cool is that?
