Solar heating is a relatively easy way to capture solar energy for our benefit.  A solar heating system saves energy, reduces utility costs, and produces clean energy.  Solar heat can be used for water heating, and space heating.  Water heating includes heating water to supply hot water in the house and heating the swimming pool and spa.  Compare to the solar power system, the construction cost of solar heating is relatively low.

Solar Collector is the key component of active solar-heating system.  There are a few types of solar heating collectors:

• Flat-plate Collectors
• Evacuated-tube Collectors
• Integral Collector-storage System
