Factors to Consider while Buying Solar Water Heater

  • Water Source- You should determine whether the water available is hard or soft. Direct Solar eater is suitable for soft water while Indirect Heaters are recommended for hard water sources. In an indirect system, the heating is done by a fluid, which gets the heat from the solar panel. Heating hard water by direct means could cause pipe blockage.
  • Size- The size of a water heater is indicated by LPD(Liters per day). A heater with 100 LPD capacity would be sufficient for a 3 member family. Accordingly, a heater with 500 or more capacity would be the minimum for industrial or commercial requirements.
  • Type of Collectors- In general, there are two types of collectors, FPC and ETC. FPCs are made of metals and get heated quickly and also lose heat quickly. They are durable but only suitable in tropical regions. ETCs are made of glass and are delicate but have better heat retention ability. They are suitable for both tropics and the temperate.
  • Tank- The tank should be able to retain heat for a long period and also be rust-free.
  • Temperature Regulation- It is best to get a water heater with a thermostat so as to maintain the temperature at an optimum level.
  • Warranty- Most water heaters come with a warranty of 5 years. If regularly serviced, the heater can last upto 15 years or more.
