Probably the most Important consideration here is, Will The Stove Fit? The size and shape of a stove, as well as it's required clearances, will determine the actual space you will need to safely install and use it. A tall stove, such as an Antique Cylinder (circular) Stove, will take up less space than a Box Stove with the same surface area; thus same heat, but larger area or Footprint for the Box Stove. You should always consider the dimensions of the stove before you buy it. What are the recommended clearances for that particular Stove? In almost all cases, no less than 18" from a combustible surface, and many States vary as to the Safety Codes. Always check with the local Fire Marshall or Fire Department, they are your Friends, and want to see that you are complying with  the Local Codes and addressing Safety Issues when installing a wood stove; this will also help on your Insurance Rates, when your Stove Installation is Inspected. Many Insurance Companies require this. You may possibly have to sacrifice some living space to install the stove that you want, or possibly settle for a more compact one that is more efficient, but remember that the more space required for the Stove itself, the Bigger the Hearth area to protect your home, and the additional hearth space equals more money to purchase/install a hearth.
