Great info, thanks!! You guys have a wealth of wood burning knoweledge!! I have a felling I'm going to as well by the time I'm done beating this to DEATH! As for burn times, I think I'm fine with 10, 12 or 14 hours. That would be perfect for me, remembering that this will only be a suplimental heat source. In the dead of winter, I could start a fire in the morning, let it burn all day long, then reload in the evening and enjoy a nice fire show, then turn it down to low and let it slow burn overnighjt so I stil have hot coals to re-load onto the next morning. I just don't want to have to "start" a new fire twice a day.... Here is a quetion, if I buy an larger than required unit, will it burn more wood faster because it is bigger, even when I don't entirely fill it, and try to turn it down? Or can you really manage a bigger unit by not loading it with alot of wood....?
