ETC Solar Water Heater


ETC Solar Water Heater


The ETC Solar Water Heater, provided by us, can be safely used for hard water or bore well water. Our ETC Solar Water Heater does not require heat exchanger for preventing scaling menace, which causes temperature loss. Moreover, the high quality glass tubes in our ETC Solar Water Heater do not choke up or corrode and can be cleaned by using a simple brush. Additionally, total height of our ETC Solar Water Heater is less than that of FPC Solar Water Heater, due to shorter cold water tank requirement.


Known For
  • Quick & easy installation
  • Higher efficiency in cloudy weather
  • 20-25 % cheaper than Flat Plate Collectors systems
  • Less floor space required for the same capacity than FPC systems
