Remodelling my basement bathroom.
Currently there is no heat register in the area where I'd like to put the bathroom, so I was thinking about tapping into the main heat duct, which fortunately happens to run right past the bathroom just outside the wall.
My question is: can I tap into the side of the main duct, or do I have to go in through the top? The side would be much more convenient, as it would only require connecting a duct that is about 2 feet long.
Any help would be much appreciated.
