Man that stinks. I have a 13 page thread going, just came across this last night. Mine is doing the exact same thing but I have a direct vent. When I first lit it just before thanksgiving I was trying to set it up like they said...find max burn, set it and forget it.....problem is the direct vent would not keep enough draft when I try and run at max rate with both burners. I am just heating my house and hot water right now burning through 2 40# bags a day with temps in the 40's-50's and running 1 burner. I will say I am impressed what 1 burner will do if you turn it up! I had some setup issues and I was burning more coal 3-4 bags a day in November. I burned 2400# in 2 and a half weeks in fairly mild temps? But like I said I am getting a better burn now and burning less but I still need to figure something out. Matt and Dave did find a trouble spot (I hope) with the direct vent fan...it was to far away from the housing so it was not working efficiently so I did move the blades about 3/4" closer which is a lot. It has been so warm though that I have not been able to fire up the second burner to see if that made a difference. I like you have my boiler in a garage 200' from the house but am only losing 1-3* on a 1" line. It is very well insulated. But all I have is a 1" line so one would think that this unit should keep up fairly easy but is proving not to be the case. I will keep working at it and get this thing to be more efficient with whatever it takes. We seem to be the only ones having issues, at least that's what it feels like. I have nothing to say but good things to all the people who are trying to help me out and because of them I have am burning 1-2 bags less a day but I still feel I am burning way to much for the outside temps. I was running mine at 180* on and 190* off like you but I turned it down to 160-170 and is doing better so far. It's nice to finally be able to talk with another owner of this boiler, hopefully we can help each other out! I'm a midnighter so it's time to call it a night, Hope to hear from ya, Shane!
Oh, BTW, my idle fire rheostats do work and my fire stays lit. I did a test just running my loop to the house and the boiler went to idle fire for 4 1/2hrs straight and the boiler temps were rising headed towards high limit so I aborted that test proving I was not losing all my heat into the ground!
