I don't see how, unless your electricity is even cheaper than dirt. It just equates to electric resistance heating, which is about the most expensive heat there is.

In fact, I'd think it's less than half as efficient as burning the propane directly. If you're getting electricity from a fossil-fueled power plant, it's converting maybe 50% - often less - of the fuel's heat energy to electricity, then there are transmission & distribution losses on top of that.
