Thanks for the input so far Joseph Glenn and Mike!
Joseph, good to hear that we could likely just throw some more fuel in to get the barrel or equivelant hot in pretty short order for cooking needs as they arrive. I honestly don't know enough about RMH yet as to have made the assumption I could do that without overshooting on the intended heat output.
Glen, glad to hear some positive feedback on likely getting enough convective heat upstairs to keep things reasonable. I won't discount passive solar gain, and will plan for it and take what we get, just won't count on it.
We are hoping to be able to build the ceiling/floor "plank on beam" as you're calling it (I've never been sure what to call it), partly for heat transfer's sake (sound transfer too though I'm sure, whatever), partly for utility's sake (I'd love to be able to just tap in trim nails and hang things as needed for example), partly for the spaciosness (I'm 6' 4" and want a compact home for heat efficiency's sake), partly because I think structural transparency is useful and homey, and partly because I'm interested in omitting materials (like ceiling drywall) and other frills wherever possible or reasonable to save on expenses. Only problem is I haven't been sure how to pursue a floor like this without doing full timber frame or something which might be (likely) out of the budget unless I do a lot of self assembly. I've been considering that, but that's a whole other can of worms probably not for this forum. Starting next weekend though, I am meeting with several generally conventional home builders to start getting ballpark bids on stick frame variations to see how small we have to ultimately build to stay in budget. After that I can really start nailing down the design. Is "plank on beam" a known or at all common ceiling/floor system for modern stick framing do you know?
I'd also be curious to know a bit more about your experience with the radiant floor and heating with RMH in tandem, since that may very well be my final scenario as well. Since it's a new build on slab, and everybody and their brother is telling me I would be reaaaaal stupid not to at least put the radiant floor heat tubes in, I have been leaning the way or radiant floor with respect to the backup/conventional heating system that would in theory only really get used in the event of winter travel or illness etc. local plumber just has an on demand electric boiler he says, and buys off peak electric for it or something. Seems like maybe the ticket for very occasional use and minimizing standby losses but I've not decided. One question that's been bother me (not that NOT having radiant floors would fix it) is if I'm living on a finished concrete slab on the main level, with radian't floor option, but don't actually (rarely) USE it (that being the goal) is it unreasonable to expect a RMH or wood stove to be able to prevent the slab from constantly feeling cold as ice? Or am I going to find myself running it just to keep the ankles warm? If thats the case then maybe I put down an overlay with less heat transfer, but again, I'm trying to keep materials to a minimum wherever I can. I'll likely just get some nice moccasins, maybe a few thick rugs too, and compression mats at sink etc. I'll be insulating below the slab of course. Stove folks have told me that radiant floor and stoves are a great combo because the floor is generally slow to tackle dynamic temps swings, and thats where the stove can step in. But in my case, I really just don't want to run the conventional system, whatever it happens to be, outside absence or illness. Still trying to figure out what the best system to rarely use is haha. Some have just suggested regular old cheap electric baseboard or wall units, but if I already have the floor tubes in.... and if the baseboards encroach on space and look stupid.... tough call for me still. Electric radiant floor? How bad an idea is that?
Thanks for clearing up the heat source close to cold surface dynamic being a pursuit of comfort, not efficiency. I thought I read somewhere though that radiant baseboard below a bay of windows for exmaple actually works to counteract heat loss at those windows. Idk, seems to me it would just more readily send that hard earned heat out the window to outers space.
The details on the rocket mass setup seem helpful, I'll refer to those ideas if/when I settle on doing rocket mass. Thanks.
Have tested the co detector. Maybe a leak in chimney but doubtful, its a straight vertical run
Mike, it could be a consequence of ash inhalation while loading I suppose. I might explain why wife has no problem, I'm the one messing with it, and do load more often than is typical, doing many half loads rather than a full. But it doesn't explain the alms instant partial relief when departing from the stove room.
Mike I haven't considered a tall masonry heater mainly because I don't think I have the budget to hire a mason. I expect a true masonry heater to be out of budget unfortunately, given prices I've heard quoted. I've seen exterior photos of that cordwood house you mention, but not the interior or its heater. Does sound a little gigantic for my application. Thanks for the idea though.
