Solar 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.
