But, wax holds much more heat energy than wood, so your claim doesn't make sense, since the one could just use more wax in place of the wood. (paraffin ~= 20,000 BTU/lb, wood ~= 6,000) >All wood has the same energy? Pretty close, by weight. >Oh wow, think of all the time I spent messing with the oak rather than >the aspen... See that was my problem, I thought I was getting more >heat from the oak than I did from the softwoods all those years. I know what you mean. If you don't study or research things, and just believe "old wive's tales," then you don't always make good choices. Don't you wish you had found out sooner that aspen holds 14.7M BTU/cord, weighs 2290 lbs/cord, and produces 6419 BTU/lb, while white oak holds 25.7M BTU/cord, and weighs 4012 lbs/cord, which is 6405 BTU/lb? So, the difference is a full 0.2% in energy per pound. The US Forest Service ranks pine at the top. Sources: http://www.daviddarling.info/encyclopedia/W/AE_wood_heat_value_BTU.html |
