I do plumbing in Austin Tx and i like to use the Navien NPE-240A2, it has the built-in in recirculation pump and we run the the water loop as close to the anglestop, shower valve etc as possible and return it back to the return inlet. When customers open the faucet, it take like 2 seconds for the how water to come out (even in a kitchen island). We also use the shortest possible flex on the hot side to reduce even more the wait. We also insulate every single hot water line with 1" thick insulation to prevent heat loss.
Hello I've had a ticklish hot water tank for 15 years recently in 2018 good results then bring a pump I saw it on This Old House where they where they said to put end of the father's fixture on your hot it water side it works quite well it takes the cold water from the hot side pumps it to the cold side and when it reaches temperature turns off and the check valve closes it could be either push button on demand or on a timer something to look into and talk about have a great one
So what do you think about recirculating pumps? I was thinking that running continuous hot chlorinated water through PEX for 30+ years sounds like a recipe for disaster, but your thoughts? (Dedicated return line to the fixture furthest away)
Well we don't really know the true life expectancy of PEX yet. Give it 20+ years and it maybe the new Polybutylene , CPVC was supposed to be the "jam" but it is garbage now. we will see.... recirculating pumps work well on tank heaters. but for tankless it's best to get one that comes with the pump on board. I don't see many dedicated return lines in residential. Most tankless use by-pass.

Yes, those pumps are neat. I have a video on them too
Awesome video ! Should do a video of Trac Pipe !
That would be a fun one
Thanks.
