Solar water heating. A hybrid solution that combines solar and conventional water heating to save energy and help the environment.

Benefits of Solar Water Heating

The average household uses 64 gallons of hot water per day for dishwashing, laundry, showers and other routine tasks. Heating all that water requires energy, which in turn costs money. However, if you harness the sun to generate hot water instead of relying solely on conventional means, you can benefit in many ways:

  • Reduce your carbon footprint and contribute to a healthier environment.
  • Save energy and reduce your monthly water heating costs by 50-80 percent.
  • Get money back on the installation in two ways—a PG&E rebate of up to $2,719 and a federal tax credit of 30 percent.*
  • Invest in a low maintenance, reliable technology that provides hot water around the clock.
*Final rebate amount will be based on the estimated savings as calculated by your contractor. Also check with your tax advisor to see if you qualify for the tax credit.

How Solar Water Heating Works 

A solar water heating system works side by side with your home’s existing water heater by preheating the water before it enters your tank. The sun does most of the work, so your conventional water heater uses less energy and costs less to operate.

1. Solar Collectors A pump circulates a liquid to the solar collectors on your roof to absorb the sun’s thermal heat. 2. Solar Storage Tank The heated liquid is pumped into coils that warm the water in the solar storage tank. 3. Conventional Water Heater Hot water flows into your existing water heater, which provides backup heating as needed. 4. Plentiful Hot Water 5. Hot water is supplied around the clock to meet all your household needs.
