FAQs – Best Geysers for Hard Water in India 2025
Q1. Why do normal geysers fail in hard water areas?
Normal geysers have regular steel tanks and basic heating elements that corrode and scale quickly due to hard water minerals, reducing efficiency and lifespan.
Q2. Which tank coating is best for hard water?
Blue Diamond, Titanium Plus, and Feroglas coatings are the best as they resist scaling and rust caused by hard water.
Q3. Is copper heating better than Incoloy for hard water?
Both are good, but copper heats water faster and has antibacterial properties, while Incoloy is more resistant to high temperatures and scaling.
Q4. Do I need a water softener with these geysers?
It’s optional, but adding a water softener can further extend the life of your geyser in very hard water conditions.
Q5. How often should I service my geyser in hard water areas?
At least once a year – to remove scaling and check the anode rod for corrosion.
