Solar power is groovy—just ask the homeowners who installed
solar water heaters in the 1970s. But many of these went on a permanent hiatus because an owner was unfamiliar with the system, and evaluting its condition may have seemed daunting.
If your home has a solar water heater and you aren't using it, consider launching its reunion tour so you can use renewable energy and save money. With international interest in
renewable energy and using resources wisely, using an existing solar water heating system could be a sustainable, feel-good way to lower your energy bill. It's essentially free, and maintaining a solar water heater properly could provide warm showers and maybe
heat your pool or
spa, too. You may need to hire a contractor or talk to the orginal manufacturer to verify the equipment is in working condition. The Department of Energy has a detailed
solar water heater maintenance list: Solar collectors may be dusty or shaded by new construction or plant growth, for instance. Consult the owner's manual or seek guidance from local contractors if your solar water heater is in good shape—it could be a cost-effective water heating solution!
