Singer Down-Flo Electric Wall Heater
Series 5990 (1.5 -2.0 kw Model) 220 volt - 20 amp circuit
Originally installed in 1980, unit worked with automatic thermostat but in reinstalling to new location, I forgot which way black/white wires go. I reconnected but unit now constantly runs (with or without heat) . I wonder if polarity should be reversed to run correctly.

I am not an electrician. But it sounds like a disaster of some scale waiting to happen. Ask an expert.

polarity makes all the difference.

that's why plugs are made the way they are now days.

keeps things from malfunctioning and burning up, shorting out.

it's the optimal performance you see... not having it polarized correctly can really shorten the life of things or operate using more power than nessesary or fluctuate...

i didn't think it mattered for the longest time but i lost alot of junk over the years and burned out a many of things because i reversed it.

I don't know your heater but the two hot lines carry 110V each. It's single phase so you could interchange them at the breaker. Wouldn't make a difference.

Probably makes no difference, you should be able to tell if it is working correctly, if not switch the wires.
