New construction with a propane NPE-240A, dedicated (insulated) hot water loop, external recirculation mode, internal pump. The water heater is in the garage so it's roughly 80' to the farthest fixture/end of the loop.
I want to schedule recirculation to 4:30 am to 10:30 pm. It appears the remote controller will do that just fine. The NaviLink is appealing because it claims to monitor gas usage. I've used what I think is a significant amount of propane in 2 months. If I could monitor usage more accurately with NaviLink, maybe I could adjust some of the parameters to still provide hot water recirc with less gas usage? The downside to me is the complication of WIFI and a phone app.
Interestingly, I don't see in my operation manual anything on settings such as return line sampling or recirc differential temp that are mentioned in other threads here, though my manual is a version 5.4 Jan. 2020 and the one on the Navien website is version 5.3 May 2019.
Opinions?
