Your water-heating bills should drop 50–80 percent if you install a solar water heater. And, of course, you’ll be shielded from future price increases in the cost of fuel.

Consider installing a solar water heater when you get a new mortgage or refinance your home. It’s a good time to make the investment without needing a lot of cash up front.
