Well I finally got my OWB installed. It's an Earthwood Woodsman 405 with 325k btu output. The furnace works awesome, I've been getting 12hr burn times. I load it in the morning around 0730 am and when i reload around 0800 pm there is still wood there. I went one day without reloading it for 18 hours and there was lots of coals still in there. I paid somebody to install it because my insurance company wanted a licensed contractor to do the work.
trench dug by hand lol
