The integral passive solar water heater. A review on solar water heating systems has been presented by vinubhai et al 2014. Passive solar systems typically are very simple. Solar systems for heating space or water can be divided into two classes passive and active systems.

However passive systems can be more reliable and may last longer. The authors stated that solar water heating is one of the most effective technologies to convert solar energy. Passive systems may be less efficient at any given moment but they are much more dependable and cost less per unit of heat captured. The essential difference is that passive systems need no auxiliary power to operate while active systems are dependent on externally driven fans or pumps.

Passive solar technologies use sunlight without active mechanical systems as contrasted to active solar such technologies convert sunlight into usable heat in water air and thermal mass cause air movement for ventilating or future use with little use of other energy sources a common example is a solarium on the equator side of a building. Integral collector storage passive systems. Passive solar water heating systems are typically less expensive than active systems but they re usually not as efficient.
