I suggest that you save your money and do as I did for my vacation house. I left my electric one installed, but added inexpensive switching to turn it off and on remotely from my Iphone (need internet but no new wiring, equipment, or install). Because it gets pretty cold there, I also added a recirculation pump that I could also run remotely to keep the pipes from freezing in winter. I turn both on when temps are quite low so pipes will not freeze or when I am on my way to visit so the water is hot when I get there (and it gives me instant hot water throughout the house as well). Keeping the hot water heater off a lot of the time reduces costs a lot.
