I think one of the lines on my OWB is frozen, but not sure. Here's the scoop:
My system is a CB classic with 2 pumps - attic furnace for upstairs only (in unheated attic) and basement standard furnace for main floor and basement. Propane backup set for 55. Area temps have been subzero for quite some time, with nasty wind chills. 2 days ago I came home to 61 degrees and found a tripped breaker, but no evidence of any other power failure. I chalked it up to a bad breaker and planned to replace it this weekend.
Very late last night I figured out the pump for the attic was not running and to make matters worse, the propane burner wasn't working either. I unplugged the pump but left the valves open, and (unwisely) chose to stay cold overnight and get the pump running in the morning. The main floor heat was fine.
Due to a series of unfortunate incidents, I was not able to get the pump running again until late this afternoon. While the pump works, it seems clear that the line is at least partially frozen. I'm at my wits end - not sure how to correct this or if I even can. The only advantage is that with the propane working up there, at least there is heat blowing past the boiler coil at the furnace.
