OMG! This is no BS!
When I was a teenager, my dad decided to put in a double-boxed wood furnace with vents holes on top that connected to the heating ducts in the house. It had electric fans under the stove box that moved air around the outside of the interior box and out into the ducts. Put it in the corner of our family room in the walk-out basement to "save money on the heating oil bill." Yeah right!
Buy wood furnace
Cut hole in wall for stove pipe
Buy stovepipe
Buy brick
Have mason make brick chimney on the outside of the house all the way up three stories
Strip walls in the corner and install heat shield tile

We spent every other weekend after sports games all summer driving into the forest, felling trees, then carry wood to truck, drive home, unload wood in pasture behind backyard, split wood, reload wood in truck, drive to house, unload wood, stack wood on patio. You handle the wood four or five times! But when you have two boys (slaves) who cares?? Got so damn hot in the family room that you could hardly stand to watch TV all winter. Lol. What a BARGAIN!
I was so sick and tired of wood heat that I put gas log fireplaces in the first two houses I built.
