The water is heated during day time and it is stored in the solar tank for a period of 48 hours without any loss of heat. The solar tank is made of stainless steel and the collectors are with aluminium body, toughened glass, copper risers and copper absorber sheet (selectively coated). We also deal with ISI approved collector. The total system is installed in the roof top and on one side of the solar tank, cold water is connected and from the other side, piping is done upto bathroom and kitchen. The requirement at the site is basically shadow free area (as mentioned) facing south and the bottom of the overhead tank to be at a minimum of 5 feet height from the roof level. You can also choose to have optional electrical heater backup for the solar system to heat up the water during rainy or cloudy days. |
