water heaters and booster Solar trade association we refer to the article entitled "Solar Water Heater" published on page 2 of the Express newspaper dated Wednesday, February 2, 2011, and would make the following corrections:
Item No. 1 - Look at the fact that professionals do not recommend the use of booster - The booster costs between Rs 400 and Rs 1500 and consumes enormous amounts of energy. In fact, the heater (booster) is part of the solar water heater, which is to say that it is installed at the time of manufacture of the device. It is sold with the heater, and does not cost anything at the time of purchase.
The heating element is very low power consumption of 1.5 kw and not 5 as stated in the article.

solar water heaters currently on the market operate on the latest technology, including "Vacuum Tubes" that are known on the world market to their unsurpassed efficiency. The Express
