Trying to decide if it is worth it or not:

two of us moving to a home in Florida, currently all electric. We are considering adding a 250 gallon LP tank for hot water, cooking, and drying clothes.

I'm trying to figure out the cost, payback time, and on-going costs. Like, with a 250 gallon tank, how often odes a family of two need to fill it. (Obviously, the answer varies, but there has to be a common average...) What maintenance is required on the tank?
