Good morning,
Our 2008 Navien NR240A started leaking in several places. After trying to repair a couple of times we decided to update to a new NPE-240A2.
The old unit pump was set to run 24/7 and has done well for the last 13 years. In order to minimize plumbing install issues, switched to NPE-240A2. House is about 95 feet wide with a return loop running between the floors. So, I guess about 200 foot hot water loop - 1" pex.
New unit has been for a couple of days and I've noticed a difference. The hot water coming to the various faucets is not as hot as before, even though the unit is set at 125. In reading the setup books, I noticed that the new heater has settings for hot water temp drop of 9 degree before activation and I think it checks temp and turns on the pump on every 20-30 min. I understand this can be changed.
Does anyone know if the old 2008 unit was set up the same way- I think it only had dip switches.
Any thoughts would be appreicated.
Thanks,
Andrew
