Partner replaced a 1969 American standard gas boiler and dying water heater with a Navien NCB 240 Combi Boiler. Heat was fine from Feb thru April. Off for last 5 months, DHW works very well at all times.
Cold snap and expected heat to come back on without issue. Heard it "click on" when I lifted the lever on the thermostat.
Yes, you read that correctly, lifted the lever. Boyfriend is the homeowner and decided he did not want the new thermostat and remote for the Navien combi Boiler. In fact he didn't even ask the installers to leave the Navien thermostat/remote her paid for.
So the thermostat that was connected to the American Standard boiler was wired for the Navien. I quietly pitched a fit because it made the most sense to install the new thermostat, but hey it's not my house. I just live here.
So 2nd night of no heat and a record low temp. BF wants to go tinker around with things and even though he's an engineer I'm not wild about thought of him messing with anything gas related. He' has a paid maintenance contract but will take 2-3 weeks for them to service it he says.
Terry Love forum literally saved our lives about 8 years ago when we had dancing disco lights and a weird power surge. BF shrugged it off, but from the assistance of TL members I alerted the Power company and it would have had dire consequences without that phone call.
So here I am again with a less pressing but annoying matter.
What's the most probable issue? Valve not opening / switching to heater from DHW correctly?
Thanks
