I've recently been getting tepid water at my faucet. Navien NPE-240A about 8 years old. I tried cleaning the air filter, water inlet filter, and condenser drain. Descaled for 30 mins. No change. Then I started changing the set temp and recorded the output temp the heater reports vs. the temp at faucets after they stabilize. Here are my results:
Flow was anywhere from 1gpm - 2.5gpm depending on faucet. Input water temp was around 55F. Faucet temps are ballpark since my thermometer sucks. Even though I don't have "before" temps, temps are noticeably different from what they were before.
No plumbing changes since we moved-in 8 years ago (newly built home). The only thing I can think of is that we had a power outage a few weeks back, but I don't recall if the issue started then or is more recent. We are also getting colder temps outside, but we've been in much colder weather before so that shouldn't matter.
Any ideas on what could be the issue? Thanks in advance!
set temp (F) | output temp (F) | faucet temp (F) |

110 | 110 | 100 |
120 | 120 | 110 |
130 | 130 | 115 |
140 | 140 | 120 |
