I love these vintage appliances. I noticed your channel about 10 years ago but just recently subsctribed. I am facinated, and fond of, the NuTone ceiling heater videos. I think that's how I discovered the channel. I remember my sister had one in the bathroom of one of the apartments she used to live in. I remeber its control panel was push buttoned with a pilot lite. Could the Nutone heaters be used in lieu of base board heaters? My thinking is the way "radiant ceiling" heat was use. Instead of having a baseboard heater, you would have these units over the places where peole would sit or stand. Controled by wall thermostat.
on these the fans run slow and speed up after the heat strip gets hot ,the motor is wired in series with the element like some cheap record players with tube amps
