Question on electrical heater

I have an Newair 208v to 240v electric fan heater. Newair SKU number NGH500GA00.

It says the power input is 208v to 240v 60 htz.

Can I operate this electric fan heater with a 50 htz (208v to 240v) power input?

You can also ask directly to the maker (on Amazon, there is a section where you can ask questions to the seller).

In my opinion, the speed of the fan "may" be slower than when run under 60Hz, but otherwise, there should not be a major problem. If used over a large number of cycles, the energy is essentially independent of the frequency, for (most, if not every) heaters.

Note that some buyers comment that they experienced some issues related to the speed of the fan. The maker also issues a warning about a possible hissing sound from the fan (no damage though) if used over 220 volt.

The heater portion of your electric fan heater will work fine at either 50 or 60 hz (assuming it is a plain old resistance heater). The fan motor would probably overheat at full load 50hz but the fan will not run at rated speed with 50 hz so it will not be running at full load so that will work in your favour. I think you would probably get away with it.
