What does such a small difference in altitude have to do with a pressure differential measured in hundredths of an inch of water? 0.05 in/H2O is 0.00368 in/Hg not much difference. Draft is a chicken and egg sort of problem no heat no draft no draft no heat. Looked up some different pines vs. oak for heat per cord and average a little more than half. If stove not up to temp draft is not so good and if closed down early never gets better in my mind. I had an Avalon Pendleton and a small stove at 1.3 CU/FT firebox and if not brought up to full temps before closing the air down not much good is happening. IF this stove the same technology as the Pendleton in a different size it will burn the same I would think. Only way to get real heat was a full load of well seasoned wood and let it go until up to temp and close down in stages then secondaries light off and runs well shut down too early or not very well seasoned wood not much happening. If me I would get a couple bundles of bio-bricks or similar and put them in the stove without crowding them together. I ran a sort of pyramid with 3 N/S 2 E/W on top of them and 1 E/W on top of the 2 E/W. Some say too many but ran fine for me and package says not to crowd them. At least this takes the wood quality out of the mix right away.Ding ding! Very good question.
The only other thing mentioned was no one sells what you have in your area and begs the question as to what they sell and is a very different type possibly better suited to the wood available?
