DIY Solar Water Heaters
How Does a Solar Water Heater Work?
A solar water heater consists of a collector to absorb sunlight and a storage tank to store hot water. The collector is mounted on the roof and connected to the storage tank through a pipe. When the sunlight hits the collector, it heats the water inside the tubes. The heated water then flows into the storage tank, ready for use.
