Wood
BTU Heat Values
The way to interpret these results is
to remember that BTU's are a measure of heat (energy) produced from
a single cord of wood. So, since hickory produces nearly twice
the BTU's of pine, a single stick of hickory will burn about twice
as long as the pine provided the stove can be dampened down to
produce the same amount of heat per hour and the efficiency remains
the same. Oak is one of your best bets for high energy content wood,
while pine or aspen (a.k.a. poplar) will get a good hot fire going
quickly since the lighter pine and aspen also burn faster.
