Solar water heaters (SWHs)

Solar water heaters (SWHs) are renewable energy technologies that use available solar heat to warm a working fluid, which heats water in a heat exchanger and stores excess heat in a thermal store. They reduce fuel consumption and avoid greenhouse gas emissions. Proper installation and education on proper use and maintenance is key to the successful use of SWH technology.
