In my totally uninsulated house, the wall temp ran about 20 degree cooler
than the air temp during the winter.

My outside walls felt cold this past winter and I wanted to check if
they were insulated. Outside of knocking a hole in the wall is there
any better way of managing the destruction to see inside the walls? If
I put the hole low to the floor will I be able to see insulation or
does it generally start further up and how big of a how is necessary?

I don't know of any magic solution, and what you observe in one wall
cavity may not be representative of any other wall cavity. That said, I
think the least intrusive method is to remove the cover plate from an
outlet or switch box and try to peer past the edge of the box. You can
carefully widen the gap with a utility knife to get a better view if you
want and can always get an oversized cover plate to cover the widened
opening if necessary.
