After reading many posts here I lean toward buying a pellet stove to replace my 24 year old oil boiler. I need to convince my wife on several fronts. My house (shown, if I have set this up correctly) is about 1800 sq ft in a climate similar to upstate NY but with more wind. We can burn 600 gallons of oil in a bad year, with the thermostat at 68 in the day and 58 at night. If we use one quarter of that oil in January, we are putting 21 million BTUs into our house in 31 days. That is only 28,000 BTU of input per hour. Any pellet stove can do that, right? But the Harmon P38 claims only 1400 sq ft, and it comes from a warmer location. What gives? Am I calculating something wrong? And what about my basement? All my pipes are down there!
