I'm working on a bathroom update. 1950s vintage, 70ish square foot,
southeast MI. I have an existing exhaust fan/light that needs
attention as birds invaded the attic and built a nest in the plastic
exhaust pipe. Since I have to crawl up there any way I'm going to
replace it with rigid metal. I figure I might as well replace the fan
itself since it is probably 25+ years old. The light has a 7 watt bulb
since I only need it for a night light.

I was looking at units such as this:

with the addition of a heater. I have the heat drop back to about 63
in the winter at night, so it would be nice to warm up the bathroom
quickly for late night trips or early in the morning if the central
heat has not caught up in time for a shower.

I would have to do some additional wiring with the heated version, but
it would not be too difficult as I have an unused attic fan that
already has a dedicated 20 amp circuit I can steal.

Are these units actually worth the extra cost and installation headache?

Does it really need a 20 amp? that's a lotta wattas.
An alternative is some with the IR heatlamp, they don't use much watts.
