What Is A Dedicated Hot Return Line?

When it comes to knowing about a dedicated return line, the clear-cut answer is this is such a system that uses a return pipe from your last sink back to the tank. 

The system acts like a hot water circulation line converter that helps convert your existing water circulation into a proficient and energy-saving hot water delivery system in your house.

Where Should I Connect The Hot Water Recirculation Line To The Water Heater? 

When installing a dedicated return line on any hot water system, most people ask the same question, where they should connect the recirculation line to their water heater because there are two points available. 

  • At the drain.
  • Or at the top of the cold water inlet.

Some people think that connecting the recirculation line at the drain can cause problems as it’s made of plastic.

On the other hand, some people say that connecting the line to the inlet will require using an additional check valve to prevent the line hot water from fostering the un-heated lines.

Here you can simply connect the recirculation line to the cold water inlet because our research says that you don’t need any check valve because your pump will only keep circulating the water into the continuous loop, and the normal water is outside that loop.
