Solar water heating uses the sun's energy to provide hot water for your home. System components for cold climates typically include a solar collector, a heat exchanger, and an insulated storage tank. The sun is used to warm a heat transfer fluid (such as a propylene glycol), which passes through the heat exchanger to transfer the sun's heat to your domestic hot water. Types of solar collectors include evacuated tube collectors (pictured here) and flat-plate collectors. For more information about solar water heating technologies, see the US Department of Energy's solar water heating information.
How much will a system cost?
Residential solar water heating systems often cost less than $10,000, and can reduce your water heating bills by 50-80%.
