You are correct in that limit. I had not thought of it as being anything that I would want/need to have both plugged in at the same time. I think of cooling as being a different season than heating, so to unplug one and plug in the other would not be a bother. Right now, I have both my heaters all disconnected to avoid heater failures killing any fish. If one does not use any type of heating or air and the outside temperature varies enough to need both, it would be a problem.
