#Solar-Water-Heater-Supplier-in-Vadodara #Geetanjali-Engineers Solar water heaters use solar energy to heat water for a variety of applications, including swimming pools, hot tubs, domestic hot water, and space heating. Solar water heaters typically use either rooftop solar collectors or evacuated tube collectors to capture the sun’s energy and transfer it to a heat exchanger, which then heats the water. In many cases, the heated water is stored in an insulated tank, while in other cases, the heated water is circulated directly to the point of use.
