Any advice highly appreciated with choosing the correct non-catalytic wood stove size. House: 1,900 sq. ft., two floors (second floor only 400 sq. ft.), low (7.5 ft) ceilings. First floor:living area, dining area/kitchen, entrance hall and stairway (all-together 900 sq ft) are well connected, but not typical open floor plan. Two bdrm. downstairs quite separated. Third bdrm upstairs above the living area. House is somewhat insulated (floor R19, attic R29, walls R?, double windows). Planning to use the wood stove as the primary heat source and supplement it with electric wall units in the distal first floor 2 bdrm (as needed). Planning to locate the wood stove centrally to the living/dining/kitchen/entrance hall area, in the living room. Mild pacific northwest (Oregon, Willamette valley, Eugene) climate: January Avg. Min 35 F, January Avg. Max 46 F, heating season from mid October to mid May. Dealer recommends the Lopi Republic 1250, definitely not a bigger stove. I like the Jotul F400 Castine because of slightly larger firebox (and thus hope of a longer burn time) and because of the look. It would be great to have an overnight burn time for some of those cold days (even short overnight is OK). My main worry is that the Castine, especially when fully loaded for the overnight burn, will produce too much heat making the house uncomfortably hot. And secondly, if only small fire maintained the stove will not be at the optimum temperature for burning, thus less efficient. I will appreciate any comment or experience in wood burning in this climate. Many thanks.
