Outside Wood Burners
Our heating costs are now essentially ZERO, combined with no longer having to buy fuel and with the new heating/cooling geo system's efficiency, overall our electric bill is essentially the same. Only about $30/month higher in the winter months compared to what it was 4/5 years ago even with the price increase WE engeries pushed through on electric rates this past winter. (Before we had an older oil furnace...at least 30 years old when it was replaced. When the blower fan kicked in you could watch the meter spin so fast you thought it might fall off.)
We seriously looked into using a wood boiler system. For us it was not worth the hassle or the cost. I would rather spend the day or two, NOT cutting wood and take a vacation away from the farm. And for those people out there burning creosote treated telephone poles in there wood burners the smell travels for miles and is nothing special.
So for people out in the country with the 300ft front or back lawns it is not as costly, ours is under an alfalfa field.
These are a lot different than the indoor woodburners and a big reason is the water jacket around the firebox, it doesn't allow the fire chamber to get hot enough to burn efficiently- I know my indoor woodburner never had any creosote buildup inside it and the outdoor one has quite a bit- both have blowers forcing air into the firebox
