Solar water heating (SWH) is the conversion of sunlight into renewable energy for water heating using a solar thermal collector. Heating water with the sun is a simple concept. Its history dates back to the beginning of time.
To understand the concept, consider your garden hose. When you get a drink of water from a hose, you often have to wait for the hot water to run out before you get cold water. We can show how to harness this heat and store it for your personal use.
Presently, an electric element that comes with a never-ending monthly bill probably heats your hot water.
To collect this natural heat, simply use a collector that gathers the sun’s rays. Then, circulate water from the panel to a storage tank, where the hot water waits until you call for it for a hot shower or to wash.
