My home is a mid-century ranch. I have re-layed the vapor barrier. I am now faced with a choice of wether or not to insulate the sub-floor OR the heating pipes. Over the years it appears that the burlap bag/fiberglass insulation has disintegrated or been taken away by rats. No matter. I can only afford to insulate one or the other. There is not a lot of room so large fiberglass bats is out of question. I have purchased the foil faced "bubble" wrap type to insulate the space. So my question is this; Insulate the sublfloor or heating ducts?

It sounds as though you are on a crawl space.
I have had successful results by insulating the walls of the crawl space. Allow the insulation to bend 90 degrees & cover the soil a foot or so from the wall. I did not attempt to attach the insulation at the bottom, but just layed scrap wood on it to hold it in place.
