I have two old stoves and a house with air leaks, bad windows, and a new addition without insulation yet. I have been reading on the other sight how great these modern stoves are, but there are a few here that do not agree. Our main stove that we have been burning for over twenty five years is a Earth stove without grates works great. Spider please make a comment on no grates air on top no problems with wet green wood. Our new stove is a Riteway furnace that is a hybrid down drafter with grates makes lots of coals. We have only been burning it for few weeks and have a lot to learn about it. WE did burn a smaller Riteway for over ten years.
let's just cut right to the chase. the only reason these new downdraft, cat, recirc, etc. stoves are being sold and pushed now, is EPA keeps cutting the particulate limit on new stoves. these stoves are NOT easy to fire. if you live in an area that isn't heavily regulated and enforced, keep your old stove. fix the draft leaks in the house, windows, get the insulation installed, and tune up the old stove. just like engines in cars with cubic inches, there's no replacement for displacement. get a wood stove with a big firebox and smoke shelf in it, to slow down the flue gas and extract maximum heat, and you'll be warm. use a manual pipe damper in the chimney pipe and that will keep more heat in the house and stove. my in-laws heated since the 1970's with a Franklin wood stove and to date I've never seen anything throw heat like that thing with a full firebox of hardwood, the draft knobs CLOSED, and the pipe damper closed. it would bake you out of the house being located in the basement, and this house has 3 floors total. they just recently switched to coal because now, wood is more expensive, and everyone is either too busy, or too old, to find and cut/split/stack/process 6-8 cords of wood/year for that household. with coal at $200/ton and wood at $150/cord, and 2 cords of wood needed to equal one ton of coal, coal has become cheaper.
if you "must" go with a new stove guess what, there's a limited list of ones that will pass the new emission laws, so the EPA is going to make most of the choices for you. If you can afford it, get a Blaze King. I'd steer away from a recirc or cat stove, because when the cat comb or recirc block cracks or burns out of it, they cost $400-$600 to replace.
it's a damned shame too because an old used stove is $100, sometimes free, but they're well on their way to outlawing them. we are going to have smoke police going around checking chimneys and issuing fines, they are already beginning to do it in some areas on the West Coast.
