Here in the cooler part of New England, my heating bill will be $0 per month or $0 per winter or $0 for the year (I like easy math) for 2400sqft. Well insulated and heated all with wood.

Sure I pay for the equipment and fuel to process the wood but I equate this cost to a gym membership.

Plus (if you read the latest university studies) I am doing the world good by selecting wood and not oil. In short not pulling something up from underground to burn that has no right being above ground, versus a dead tree would emit the same gases when dead plus new growth forest is better for a green earth.

Been heating with wood all my adult life and the one thing I witnessed in Europe and is key to any heating is the air that is burned. Applies to any type of combustible heat source in a house and is similar to why we all consider a regular fireplace so inefficient.

If your heat source (no matter what it might be) uses air inside the structure to burn , not only is it burning air that you already heated even more damaging it is creating a negative pressure in the house. This pressure will of course try to even itself out by sucking in outside cold air.

I have seen studies where 10% to 14% of savings where realized just by drawing in outside air to burn.

Unfortunately the trend has not caught on in the US as much, but I see it from time to time. My wood stove comes from Norway and I would not trade it for the world. It has duct work much like a dryer to suck air from the outside, thus the combustion gases and all are completely isolated from the inside air. Same with the oil heater here (if needed).

While I do not keep the house hot and the temp inside swings a lot, I will use about 5 cord a wood this year and half of that will be pine ( please no preaching about burning pine).....

I did look into Geo-thermal to compliment the wood. But like electric cars all I see is switching from one evil that you have no control over (oil or gas) to another evil that you have no control over (electricity).

Much like another poster mentioned they went back to 50 year old technology and switched to coal and saved significantly. I would much rather go back 100 years and save it all. Plus I stay warm when the lights are out. :)
