If you are using that much propane for water heating and nothing else in
the house uses propane, you would probably be better off switching to an
electric water heater. I was using somewhere around a gallon/day for
mine (1 person), and when I switched to electric, I barely noticed any
increase on the electric bill. Larry

You must have cheap electric. Where I live the same amount of energy from
electric will cost 35% more than propane. Oil is considerably less that
either so I'd look at that option first.
For 100,000 Btu of heat here in CT, the cost is as follows
Electric 4.75
Propane 3.33
Oil 1.86

I don't know the cost of natural gas right now.
