I am pretty new here, and was wondering if picking the right pellet stove is as easy as observing usage of your current fuel source? Example: I currently have an oil boiler. Over the last week, during the cold snap, we have averaged burning around 3 gallons per day. Based on the assumption that there are 119,000 BTU's in a gallon of oil, based on a boiler with 85% efficiency, that equals 357,000 BUT's per day. If a pound of pellets contains 6,000 BTU's, based on a stove with 75% efficiency, that means I need to burn 60 pounds of pellets per day to equal the output of the oil boiler. Or a stove that is capable of putting out roughly 15,000 BTU's per hour. Is it this simple? Or is there more I need to consider?
