I have a small house, no basement, just a crawl space for the furnace, hot water heater, water softener. Would it save me money to open the duct work on the furnace to heat the area, or keep it closed so all the heat goes up to the house?

If the crawl space is encapsulated and since heated air rises, wouldn’t one achieve warm floors at minimal cost if the crawlspace were heated?
That’s what I am wondering, too. Makes perfect sense to me!
