Solar Water Heating

A simple, but important first step towards big energy savings.

Did you know your home’s largest energy hog is the electric water heater especially if you don’t have air conditioning or a swimming pool? For families of four or more, installing a solar water heater can save you at least $600 on your electric bill per year. That’s enough to buy 200 pairs of slippers!

Are You Ready For Solar Water Heating?

A solar water heating system harnesses the sun’s energy to heat water, so your water heater uses less electricity to do the same work.
