I am considering an outdoor type wood burning furnace to heat my house. It is presently heated by oil hot air. If you have an outdoor furnace, has it met your expectations? What make do you have? How often must you add wood? How much wood do you burn/year? What is the size of your house?

We are thinking about getting an add on wood burning furnace. Wondering if we need to make changes to the existing flue, or need to go with a wood burning stove instead. Advice as well as informative links would be appreciated. Thank you.

After a friend in Iowa told me that they heat their house to 80 degrees for only $1 per day, I had to figure out a better way to do what I am doing. They use a shelled-corn-fueled-furnace. After doing some research I have found that many recommend wood pellet furnaces. So, which is most efficient and which has a stronger future (ie. fuel supply, less volatile price for the commodity, etc.)? Thanks

We have a wood burning furnace that is hooked up to our central ht/ac. I have heard that black mold spores are dangerous to your health. I'm wondering if I burn wood that is covered in black mold if it will incernate it or release it into the air. It runs through a filter on the central heat unit, but I'm not sure if I need a special filter or not. I'm curious since one of my children has asthma. I grew up burning wood and have asked everyone I know and no one has an answer. Anyone out there can you help me?
