Because the heating elements heat the water in this fashion and come into direct contact with the hard water, the hard water causes the heating element to scale. To prevent this from happening and to extend the heater’s lifespan, the heater should be completely covered in any glass material.
  3. Anode Rod; Anode Rod has a lifespan of two times as long, works in various water conditions, and guards the tank and heating element against corrosion. Therefore, you must ensure that the geyser you choose has a sturdy rod. Magnesium, which is resistant to corrosion, was used to make the best anode.
  4. Size; Size is also the main feature of a water geyser. Always prefer that which needs you and suits your needs.
  5. Warranty; The most crucial element you must consider when shopping is the warranty. Because if you want a hard water geyser that will last for a long time, Then you should look into the heating element and tank warranties. That you can replace or repair something if necessary.
