well well now... this is funny because we used to own many sailboats and ive used many boat stoves in my youth... these were great lil' units but these are not really for a home (or even a room), they are for boats, cars, RV's, etc. They are thin to be sure and put out very swift heat in a small area. You cant use anthracite (well, maybe you could burn a few peices in the middle but we all know anthracite wont burn like this
), if you filled the pot with anthracite it would make this lil' guy buckle, twist and fold up like a cheap suitcase. Edey & Duff made a quality cast iron unit you might get away with it in, but ive seen them all and the best one i ever used was called a Shipmate and if i were looking for a product like this i would search high and low until i got my hands on a shipmate!!!
EDIT: found it... the one i used was acually called a "Skippy"
they appear to make them still http://www.shipmatestove.com/Details.cf ... category=6
BUT...look at those prices
