It seems like it would only be close to “reasonable” to run in a place where snow is so minimal that you don’t even need to bother dealing with it.
But if you live somewhere like where I live, where a bad storm is 10-14” of snow, that’s gotta take what, days of running the system?
I would think if you’re getting heavy enough snowfall it would outpace the heating effect. I don’t know, no one around here has one.
