Now that I have my new smoker I am trying to figure out the most efficient heat source. For those of you who have not seen pics yet, it is an 8ft smoker w/ a top baffel system, which really is irelevant to my question. I know that there are several factors that contribute to the cost of fuel: price of wood vs. charcoal, availability, etc. My question is: which is more effecient all the way around? Keeping in mind that I will need to pre-burn my wood before using it (time) vs. using charcoal ($$) what is the best heat source? Does wood burn longer than charcoal? I know charcoal usually burns hotter but longer?? Any advice would be greatly appreciated!! Thanks!
