I'm in a dilemma and am looking for some help, not knowing any experts in the area. We have a drafty 55 year old 24 x 40 rancher that we are trying to heat from the basement with an outside lined masonary chimney. Total chimney rise is 26 to 27 feet with a total length of about 30 feet. This puts it within code for roof clearence. For the prior 3 years I used a Century Hearth stove that was rated for up to 1000 square feet with good results using about 2 1/4 to 2 1/2 cords per year. Other than the small firebox our only complaint was that once the temperatures dropped below 30 degrees the stove could no longer keep the house warm. Seeing where oil prices were going I bought a Napoleon 1400 PL last spring and sold the Century. With the 1400 PL being twice the size of the Century I am confused and disappointed with the results. I am burning twice the wood and gaining almost no heat increase on either floor. The stove does not maintain a high temperature very long and always has 2 to 3 inches of hot coals that are hard to burn up. This was not a big problem with the Century. I'm thinking it is a draft problem since the stove has to be ran with the damper wide open in order to maintain 200 to 300 degrees except when first fully loaded. Forget trying to burn 4 to 6 inch rounds. Putting an interior chimney or moving the stove to the main floor is financially impossible at this time. Would going back to a smaller firebox stove be more efficient since the chimney apparently cannot draft the bigger stove? I feel like I'm wasting too much time and energy prepping wood and not getting the heat I want in return. I'm open to any suggestions.
