Just converted to Navien NHB-150 boiler from a 30 year old oil boiler. Still just learning and installer is on vacation.
I press the display mode button 3 times, until it says info. Press + for the supply temp, 148. Press + again for return and its 149? I know I don't have enough radiation for this zone for high efficiency ( about 25' baseboard and 2 8K btu kickspace heaters (one who's aquastat won't close at this water temperature), but shouldn't I see some type of temperature drop?
Its a warm day today, in the 40s, house has been at 68 for hours, turned this thermostat to 71 degrees to see what the supply and return temperatures would do. Sometimes the return temp is a few degrees colder than supply, sometimes the same, and some times a degree or 2 above.
Thanks for any suggetions.
