We went through a major remodel where a lot of walls came down, plumbing was redone in multiple locations, new PEX was run almost everywhere. We asked for recirculation for instant hot water and have a recirculating water heater Navian npe-240a2.
Shower is about 30 feet from the water heater and takes about 15-20 secs to get hot when recirculation mode is on (I set the timer to on, and I hear the water heater turn on in that window and running). To me this sounds like we do not have a recirculating line. Plumber said this behavior was expected. I tried to ask him for clarification on how the recirculating line was installed and a diagram, but could not get a clear understanding. He explained that the recirculating line installed to the furthest point (kitchen), and also mentioned you cannot branch from the recirculating line, so it sounded like all hot water still had to originate from location of water heater. To me it sounds like recirculating line is a loop that warms up water to be pushed to the rest of the house when we turn on a fixture. I would actually say the kitchen and the shower in question are both just as far from water heater, in a triangle, and other bathrooms are closer to the line between the kitchen and water heater.
Questions:
1. Is this how a proper recirculating line works, taking tens of seconds to heat?
2. Anyone know what questions I can ask to GC or plumber to get clarification? GC is looking for final payment so I'm trying to understand if this is normal.
3. Was there a way to run lines to make sure everything was minimal delay for hot water when walls were down?
Thanks so much in advance!
