current building code where I live dictates that heater/fan units in a bathroom require their own circuit. Just an FYI. I had one installed back in 2002 when I purchased my house. And it should be on a GFCI circuit as moisture from the shower/tub in the form of steam can get into the fan motor portion and cause a short. Now all this is to do it right, safely, and up to code (based on Seattle's building code).
