Built in bathroom heater/fan on 15 A circuit. Possible?

I've had a request to replace an existing light/ exhaust fan with a heater/ fan combo.
I don't think it's possible on the current 15A breakers and 14G wire that goes to that bathroom.
I think they'll need to stick to a small space heater plugged into the wall outlet.

I think you would need 12g wire 20amp breaker. I'm not an electrician though.

It looks like there are some that are 15A acceptable. Of course it should be on it’s dedicated circuit, not shared with the receptacles or anything.
For example:
4-Sone 70-CFM White Bathroom Fan and Heater

I saw one like that, but that's 1300W or about 11A. I always thought you try to keep "normal" running amps around 60% of rated breaker. Maybe not?

80% of breaker if continuous load.

That heater will be used 2/3 times a year

If you are worried about code I am 95% sure NEC requires bathroom heaters to be on a dedicated 20A circuit.
