I posted on this issue some years ago and got flamed off but I remain resolute.  Do not buy a Spanish wood burning stove -full stop.  They are made of thin steel sheet, will bend and permit uncontrolled combustion.  You'll be sold nasty thin walled flue pipes that will bleed creosote at every joint . You must go for a solidily built cast iron one such as Dovre, Jotul etc. and get enamaled steel pipes in the house, then twin walled stainless steel tubing through the roof and out into the atmosphere.    Google for Scandinavian, Belgian or British stoves.  Anything less is a complete waste of money and will reflect on the resale value of the house.  I will get flamed.  Your call.
