/edit -- oh, side question on solid firebox fuel... with my boilers up to full heat, do you guys see any reason I should be converting logs to charcoal? I am thinking I should be able to pipe logs directly to my fireboxes and just eliminate the charcoal conversion at this point. What do you think?
I run 2 solids on planks and I'm slowly generating extra logs. Logs and planks give the same heat, so as a pure guess based on the output of my SC tree farm (16x16 E shape) I'd say no. It would triple my log usage to run just one solid boiler; I don't think I'm producing excess fast enough for that. But with a larger tree farm, it would become feasible but not ideal.
