Looking to install a new stove here very soon and really need help. We're looking to heat 4100 sqft as much as possible in Northern Virginia. The main floor is 2300 sqft with 500 being 23ft. vaulted ceilings and the house is an open floor plan. What cast iron style wood stoves would be up to it, I do not want a catalytic stove. I was looking at the Quadrafire Explorer 2 and then saw the Explorer 3, not sure I want a first year model. Any advice/help truly appreciated, this will be our first stove.
