One Zone Stopped Working (troubleshooting ideas or call a plumber?)
I have a tankless oil water heater with 4 zones (2 up 2 main level) of baseboard heat. Just yesterday one zone stopped working. Baseboard is cool and both ends up pipe are cool in this zone.
I checked the temp on what I believe are the return pipes for each zone and they are all 100+ degrees.
My main question is how do I troubleshoot whether I have a thermostat issue or something else? As part of an energy audit by Mass Save a month+ ago they put in a timer thermostat in the zone affected. I could try putting back the old thermostat.
I've read several other posts and have heard about possible frozen pipes, air in the system, etc, so wasn't sure where to start. I'm probably not comfortable doing anything to my system that requires emptying the water, so I may be in the 'call a plumber' category. Thanks!
Some pictures of a few pieces of the system attached if that helps.
