I have a space in finish basement where I have to supply heat from ceiling. But in ceiling, in some places, main supply trunk is not reachable or some occupied by other vent for upstairs. Now I am ending up with reuse the existing branch of 7" flexible duct, which goes up stairs currently. I think I just have add a tee and then attach boot. I know cons of splitting the supply.
I need to know what register vent boot, do I have to use which is compatible with duct tee or How do i achieve this ?
The joists in ceiling running 16 inch center and 2 in. x 10 in. in size. The floor space in basement is 180 sqft
Any help will be highly appreciated.
