Insulating ductwork

[Aseret_in_MO]

My basement is not finished. The ceilings are less than 8 ft in height. The walls of the basement are very thick - Stone/granite foundation. I would say that so far this year, the basement has been around 55-60 degrees on the chilliest days.

Would insulating the ductwork be a good way to save on heating costs? Although the furnace is new, the ductwork is very old, probably original to the house or at least when they converted from oil to gas furnace.

Thanks.

You dont say if you have AC on this furnace down there.. Ill say no dont do it any heat that gets out down there is in the home and helps to warm the floors so its not a loss. We always cut one or two registers in the duct down there to cut the chill off down there. It would pay to stud the walls and put insulation in them. For right now check up on the sill plate in the joist they should have block of R -19 insulation cut and fit in there. All around the home. It sure helps
