Hi Chris:

We extract honey without heating. We used to put the stuff in a hot
room and leave it for a day to reduce the moisture content, but it
really doesn't make any difference to the extracting. The combs seem
to break up a lot more if they are hot. You don't want to leave them
very long before extracting because they will granulate and then you
can't extract them at all.
