Me & my husband installed a wood/coal furnace in our last house, couldn't stomach the price of gas, we built the chimney and spent alot of time gathering free wood, we saved alot of
$$ in those 2 year living there. But it was alot of work. Here is one of our piles before he got the maul & axe out, my dad let us borrow his Log splitter, that was a blessing... I was the Stacker.
We sold that house, now we have oil heat.
My husband still entertains the idea of getting one of those outdoor wood furnaces for our house. Still throwing the idea around... we can make it so it can heat our garage & the house with underground piping. I used to visit forums on these things trying to decide & checking them out at the Fairs. But we just never took the plunge to get one yet. I know they will take alot more wood than the indoor ones, but one plus -you can throw HUGE logs in there & they'll burn all day long.
We're not sure we want to go back to all that work of searching for wood, I don't feel like chopping all our trees down to heat our house. I like my woods. But we had some fond memories from using wood heat too.
