yes, i have seen a sedore! i've got one in my dining room.
it's a sedore 3000.
my husband (an anal-retentive engineer) asked the US manufacturer tons of questions before we purchased our stove. the manuf. said that the sedore actually will burn coal, but it's not UL-approved for it.
ya know, it'd be a shame to not go sedore just because it sounds too good to be true. some of the dealers offer guarantees. so, you could get your money back if you find it really is too good to be true. right?
we burn all sorts of things in our stove. we've cut our trash load almost in half, because now we have a productive place to throw our paper and cardboard. even our cornstalks from the garden are going into the stove this winter!
we have our sedore hooked up to our hot water heater, which has been lovely. during the cold months, i can run the dishwasher, laundry, shower AND a bath without running out of hot water.
our house is not set up for radiant heat, but i know other sedore-users (including the manufacturer) run their stoves through their hydronic radiant heat system.
here's an image off of the website we purchased our stove from:http://sedorestoveWEST.com
my stove is just like the one in the picture, with the red color. i insisted to my husband that we make it a fun color, since it does take up some space, and we don't use it all year-round.
i hope that helps your search!
