Navien NCB210 Heating Help
Hello all I am running into some problems with my new install.
I finished my install today and fired it up at 9AM, it took 6 hours to reach 70 degrees from 56 starting temp. Does not seem normal to me. Single Zone, 1400sqft 65 Feet of Baseboard, Temp set to 180, 20 degree delta. What is the deal here ? Unit is at 31 PSI pressure which does not seem normal to me on top of the i have a manual gauge on the manifold supply tee and that reads 20. What gives ? I have purged the unit and i am pretty sure its not an air problem. I have a 1/25HP circulator on the supply side, could it be that it is too weak to overcome the primary loop pump ? All baseboard piping feels very hot. Here is the install picture for piping purposes, its been completed since. -I am hoping i'm missing something here ?
