Haier Electric Water Heaters: Features Built for Hard Water

• The defence of Haier against hard water lies not in the coating but in the material used for making the tank. 
• The tank of ED and Precis Pro models is made either of Incoloy 800 or titanium-coated, and it is also equipped with a glass coating that prevents any corrosion or scale. 
• In addition, since the tank is protected by the shock-proof technology keeping the voltage up to 5V throughout its whole life cycle, there are no safety risks regardless of the mineral presence in the water.

Crompton Geysers: How Do They Tackle Mineral Deposits?

• The Crompton technology relies heavily on coating and a physical barrier to corrosion.
• Their Glassline and Anti-Scale coatings are benchmarked on water with TDS of up to 2000 ppm, hence providing customers with a concrete number to measure their water hardness.
• The Acenza model includes a Sacrificial Anode rod (a device which corrodes in lieu of the tank itself), making the tank work for longer periods in areas where there is scale build-up.
• In light of the 5-level safety systems used by Crompton across their 5-star rated models, Crompton puts an emphasis on damage prevention through coating, not the tank itself.
