Solar water heating systems almost always require a backup system for cloudy days and times of increased demand. usually provide backup and may already be part of the solar system package. A backup system may also be part of the solar collector, such as rooftop tanks with thermosyphon systems. Since an integral-collector storage system already stores hot water in addition to collecting solar heat, it may be packaged with a for backup.

Water flows through the system when warm water rises as cooler water sinks. The collector must be installed below the storage tank so that warm water will rise into the tank. These systems are reliable, but contractors must pay careful attention to the roof design because of the heavy storage tank. They are usually more expensive than integral collector-storage passive systems.

• Integral collector-storage passive systems

  These work best in areas where temperatures rarely fall below freezing. They also work well in households with significant daytime and evening hot-water needs.

  2) Passive solar water heating systems are typically less expensive than active systems, but they're usually not as efficient. However, passive systems can be more reliable and may last longer. There are two basic types of passive systems.

  Pumps circulate a non-freezing, through the collectors and a . This heats the water that then flows into the home. They are popular in climates prone to freezing temperatures.

  B: Indirect circulation systems

  Pumps circulate household water through the collectors and into the home. They work well in climates where it rarely freezes.

  A: Direct circulation systems

  1) There are two types of active solar water heating systems:

  Most solar water heaters require a well-insulated storage tank. Solar storage tanks have an additional outlet and inlet connected to and from the collector. In two-tank systems, the solar water heater preheats water before it enters the conventional water heater. In one-tank systems, the back-up heater is combined with the solar storage in one tank.

  2. How Solar Water Heater Work?

  Solar water heating systems include storage tanks and solar collectors. There are two types of solar water heating systems: active, which have circulating pumps and controls, and passive, which don't.
