Using the sun’s energy to heat water is not a new idea. More than one hundred years ago, black painted water tanks were used as simple solar water heaters in a number of countries. Solar water heating (SWH) technology has greatly improved during the past century. Today there are more than 30 million solar collectors installed around the globe.
Solar water heating systems use solar collectors and a liquid handling unit to transfer heat to the load, generally via a storage tank. The liquid handling unit includes the pump(s) used to circulate the working fluid from the collectors to the storage tank, control and safety equipment. When properly designed, solar water heaters will work when the outside temperature is well below freezing and are protected from overheating on hot, sunny days. Many systems also have a back-up heater to ensure that all of the consumer’s hot water needs are met even when there is insufficient sunshine.
