That, IMO is gonna be your ultimate problem with this project. Air not warm enough by the time it reaches Mrs Cat.
It is a real issue with warm air wood furnaces, I've seen indoor installs that didn't work out just because the duct runs were too long or ran through a "unconditioned" space. I would hazard a guess that you have a unfinished basement? Gonna be a real sum beach getting warm air to the rooms running through cold ducts. You would think they would warm up eventually and then transfer heat to the house...doesn't seem to work that way. But when you have the furnace in the basement it heats things up enough just from radiant heat to help offset the duct losses...and it is much closer, so that helps a lot too. Oh, and don't forget, warm air rises, so most indoor installs have warm air flowing to some degree all the time.
The other issue with long ducts is cold air purge. When the blower kicks on you get a blast of cold air...I would think this is even more of an issue in a outdoor set up like this...MC (Mrs Cat) prolly not gonna like CAB (Cold Air Blast) which, with the cyclical nature of a blower on a wood furnace could be a deal breaker even if you get past the other hurdles
Oh and just a tip @catriverrat ...when you reply to somebody just hit the reply button, no need to also highlight and quote them unless you want to just reply to part of their comment...then just highlight and hit the popup "quote" button in that case...the double quotes were makin me cross eyed (er)
that's BBTUs (buttloads BTUs)
