Heat transfer is faster where the delta T is higher. The larger the
difference in temperature, the faster the heat transfer.
I suspect that the greatest delta T is between the inside of the
crawlspace and the outside air through the uninsulated side walls of
the crawlspace; and not so much between the floor above and the floor
of the crawlspace below.
That is why I think that insulating the now-uninsulated side walls of
the crawlspace would be the best (and easiest, and least expensive)
first option. I think that is where the most significant heat loss
is located.
Yes, that's what makes the most common sense to me.
I you do decide to go ahead and do that, let us know if it seemed to work
and solve the problem.
