Do you have other gas usage, besides the WH? Even if you do, you should
have a good idea of how much it's costing per month. In the summer
months there won't be furnace usage, if you have one. Only WH, cooking,
maybe a dryer. Here in the summer the gas bill for just the water heater
is $20 or less. It would be a hell of a long payback to switch that out.
And that's with just the old style WH with pilot. Newer ones that are
more efficient are another choice. Maybe there is a rebate for those?

Beware the hucksters and hippies.

If there is a furnace that is not used for many months, I bet the
minimum connection fee (however it is called) would be more than what
the gas water heater uses, or close to it every month. In that case you
could almost say you are heating the water for free.

Even at the $ 20 per month you are looking at over 10 years for a
payback. Then it is probably time to replace the water heater with
another that is much more than a standard gas heater.

While many things like the heat pump water heater are nice, they are
just not redy for 'prime time'. Just like the electric cars for many
areas.
