Do you know that 18% of domestic energy is used in water heating? Yes, heating water is an expensive affair which requires a significant amount of energy. In businesses and home, energy is generated from oil, gas and fossil fuels. Domestically and in some manufacturing business, it would be hard to manage. Instead of relying on fossil fuels it is better to opt for solar hot water systems.  we can save energy and environment too. They are getting more affordable and efficient with each passing year.

Household water is circulated through the collectors. They are suitable for areas where temperatures don’t decrease below zero.

Indirect circulation system: 

Heat transfer fluid is circulated through a heat exchanger and the collectors.  They are popular in freezing temperature regions.


Integral collector-storage passive systems:

They are suitable for areas where temperatures rarely decrease below freezing. They work well for household significant hot-water requirements.
