I posted awhile ago about our older 1300 sf two story cabin in the Cascades that needs greater efficiency from it's original 1920's masonry fireplace in the living room and wood cookstove in the always cold kitchen. Begreen and the rest of you were very helpful in getting me to focus I asked one of the most established sweeps in our area to scope out our situation. He says the cookstove's chimney draft is too short and kinky and chimney stack is unsafe for alot of reasons (Something mentioned by Joful) So we are putting off new wood-=heat in the kitchen until a drier season and putting in a small baseboard there for quickheat when we arrive late. (little Morso or Jotul out there later when we can suffer thru a 5' hoe in the roof for several days) Main issue is the big masonry hole in the house must be plugged. The local prosweep/stove dealer stated that a rear vent stove is better than a top vent stove in regards to cleaning because the baffle takes o bigger hit for cleaning on the top vent than the rear vent connected with a T connector. Is this accurate? FWIW - We'd narrowed our choices to something about 28"x3 with a 1.5- 2 CF firebox, with firescreen for occasional s'mores and cooktop/winter grill capabilities for power outages. Our pictured fireplace specs are 43wide front 27"wide back arch 30-33-30 depth = 27" bottom o box 16" @ top of box hearth 22.5" deep 25'+ brick chimney Stoves we're considering now are: Alderea T5 (top vent); Napoleon 1400c & 1600c (rear ven t) ; Hearthstone Shelburne (rear vent) and anything else the community here thinks we should look at. Thanks!
