There are two main types of solar heating. The first is active solar heating, which heats either liquid or air in its collector. Then the solar collector will move the air or water into a building, storage area or any other location. On the other side of the spectrum there is what is called passive solar heating. This method of solar heating relies on the design of the place it is going to heat. The structure of the area determines where the heat will collect and how it will be distributed.

A typical household solar heating system consists of a solar panel (or solar collector) with a heat transfer fluid flowing through it to transport the heat energy collected to somewhere useful, usually a hot water tank or household radiators. The solar panel is located somewhere with good light levels throughout the day, often on the roof of the building. A pump pushes the heat transfer liquid (often just treated water) through the panel. The heat is thus taken from the panel and transferred to a storage container.
In a simple system the water for consumption or heating can directly be heated in the collectors. If the tank can be installed at a level higher than the collector a pump is not needed: the hot water rises by itself into the tank and the cold water sinks into the collector (Thermosiphon system). This system is cheap and easy to build and can be found in many developing countries.
