Thank you for the replies.
I do not have any tank pad heaters, from a visual I had on the tanks when I repaired the tank level gage wires.
I will have to dig deeper to look for the furnace duct so I can seal it up.
I do have the duct work running up through the basement storage to feed the bedroom and shower area, this also has some holes to allow warm air into the storage area...which I have sealed off right now.
However, I will wait for warmer weather before I crawl around under the unit.
