CSI-Thermal Program (Solar Water Heating)

solar water heater san diegoSolar water heating (SWH) systems reduce greenhouse gas emissions and conserve fossil fuel resources, while cutting energy use and saving money on utility bills. Systems can offset up to 75% of the natural gas, electricity or propane used by your current water heater. SWH systems work to supplement the existing water heater - you do not need to replace or remove it.

SWH systems preheat the water used in a home or business (such as showers, dishwashers or sinks) and can help protect consumers against future gas and electricity shortages, as well as price increases. They help preserve the environment by eliminating carbon dioxide emissions and reducing harmful pollutants. For more information visit the Solar Water Heating Resources.

There are currently financial incentives available to install a Solar Water Heater on your home or business.  To learn how to apply for a rebate with the CSI-Thermal Program, please visit: www.gosolarcalifornia.org/solarwater/ or visit our FAQs about CSI Themal.

SWH Fact

Solar Water Heating (SWH) makes good sense. The lifecycle cost of using a SWH system to heat water is lower than using gas and electricity at current prices.

Notable & Quotable

"Powering the world's growing population and economy could require 50 to 60 percent more energy by the year 2030. That means more use of fossil fuels, biomass, nuclear power and alternative energy."

- National Petroleum Council, July 2007
