No Bedroom Heat
2007 Imperial won't heat in bedroom or bathroom. Lots of heat in front part of coach. First cold weather with rig and first experience with Aqua hot system. Any ideas?

I think you may have a problem with the zone circulation pump. If you feel comfortable taking the cover off your aqua hot you will see the circulation pumps. when you turn that zone on you should see and hear that zone pump running. if not some times you can give it a little rap and it may start. if not it may need to be replaced. that will give you a starting point.

There is a check valve on the output line that can become stuck. A sharp rap with a small wrench or screwdriver handle on the valve should jar it free.
I had all zones turned up, green lights for each zone were light indicating demand, all pumps were running. It was fairly obvious by feeling the pipe which zone was cool and not flowing. Or just give them all a rap. :-)

Before you start tearing things apart and banging on stuff, make sure zone 2 on the thermostat is turned to heat. Zone 1 is the front of the coach and zone 2 is the rear.

Thanks for all the info. The pump in that zone wasn't working. Turns out loose thermostat wire was the problem. Took thermostat off wall and disconnected main wire, cleaned, and re-attached and everything worked fine. Also loose wire on circuit board so that might have been a factor as well

The check valves are part of an Aquahot system. It sounds like you have a forced air setup.
On the front of the Aquahot unit there are a couple of screws holding a panel in place. Remove the screws and the panel can be moved to expose the circulation pumps. There is a short piece of plastic pipe on the output of the pump, about 8-10" long that has a metal fitting about 2" long attached inline. Inside that fitting is the check valve.
