Steve,

Forgive me for asking such an obvious question, but wouldn't it be simpler
and cheaper to simply build a small heated addition to your building to
house a simple tank system?  It would seem that the tricky prospects of
keeping the syrup from freezing, not to mention fuel costs, specialized
tanks, machinery, etc., would most likely be far more cost prohibitive than
a simple insulated pole structure.

Just thinking out loud.

Regards,

Todd.
