they seem to think the Fireview would be a better fit for our size house (which is actually the one we were considering to begin with; the price tag is about a grand less on the Absolute at the moment tho...).The only thing that I'm struggling with is no ash pan.
Before Woodstocks, I had a Dutchwest 2460. That's when I got spoiled on the ash grate. I also picked up a Fireview for a while, before really learning how much heat I could get out of the Keystone, thinking I would need more firepower. It was a notch up in output from the Keystone, but not a huge leap, so I figured I would be fine with the Keystone if I tightened up the air leaks in the house a bit. There's no wall insulation here, and the wind can get between the walls and the 1" wallboard, pulling heat out of the house. It's about 1000 sq.ft. We keep the mudroom/bedroom door open about 6", and it stays a nice sleeping temp out there. The wood stove is our only heat now but we plan to get supplemental heat.
I got pretty good at shoveling ash out and keeping the dust pulling in the door of the Fireview, but it's a pain. Multiply that by how many times you will have to do it as the years roll by, and to me there's no substitute for having the grate. Plus the Keystone has a nice, big window. You can see the cat glow from the couch.
I know it gets cold where you are, my wife's cousin lives in Spokane. But I'm assuming that in new construction the insulation and air-sealing will be good. I'd bet the Keystone would handle it most of the time, and leave you coals to start, but my experience is with hardwoods, mostly Red Oak, medium-high output wood. If you are burning Pine you might need a bigger firebox to have coals left. But once you get better using kindling and firestarters, starting a fire is not too big a deal, and takes not much more time to get the stove up to temp, cat light and stove cruising, as loading onto a coal bed which isn't real big. Burning Pine, you may opt for a bigger firebox to stretch out the burn.
I also assume you have backup heat..?
You
could go for the AS, where you have a big window, ash grate, welded steel box with no cemented seams that will eventually leak (although it may be many years before they need attention.)
The other contender next to the Fireview is the Hearthstone Shelburne. What I don't like on that one is that it only claims to have an 8 hr burn time. The firebox is the same size as the Fireview too, which I don't understand; as Fireview is 10-12 hrs. Is that because the Fireview is a cat?
Yes, cat stoves can run lower and stretch out the load. With your tight house, you may be able to run on low quite a bit.
I know the Fireview has two layers of soapstone and the quality on those things is second to none. Those guys at Woodstock seem to bleed wood stoves. Any thoughts or opinions on the two?
My SIL got a used Fireview, that's when I saw the quality construction and thoughtful engineering. I had no qualms about buying the Keystone, sight unseen. I've never seen an AS, but what I've seen in the others inspires confidence.
The Fireview came to mind when I first read your post. It is an easier install with the 6" flue requirement vs the Keystone's 7".
Woodstock says it's fine to run the Keystone on a 6" chimney, which is what I'm doing using their 7 to 6" adapter. I saw no difference in apparent draft between the Ks and Fv, with both rear-vented. They are both easy breathers.
