I recently remodelled a small basement bathroom and added an exhaust
fan & a shower.
Now after a year of use, I'm finding that I really need to tie it into
my central heating/cooling system for my house to keep the air moving,
and to ensure it stays an acceptable temperature. (The previous owners
had never done so.)
Should I tie it into the output of my forced air system (blowing into
the bathroom) or should I tie it into the air return? My thought is
the former, however I have seen the latter done on several occasions
(to continue venting the air from a bathroom even after the exhaust
fan is shut off).
Thanks for any info,
