Trying to understand my Winnebago Basement Heat

One clarification is that you don't have "electric heat" in the normal sense, that is, there are no electric heating elements in the unit. So, it will work when you run out of propane, but only if the outside temperature is high enough for the heat pump to pull heat out - about 35-40 degrees or higher. Below that, the heat pump's efficiency essentially drops to almost negligible
