- Element works harder, consuming 30% more electricity
- Scale buildup causes element burnout (3-5 years vs 7-10 years)
- Tank sediment reduces effective capacity by 20-30%
- Accelerated anode rod erosion in glass-lined tanks
Hard water service schedule:
- Every 6 months: Professional descaling service (₹800-₹1,200)
- Monthly: DIY partial sediment drain (2-3 liters via drain valve)
- Quarterly: TPR valve cleaning (calcium buildup clogs valve)
Long-term solutions for hard water:
- Install whole-house water softener (₹8,000-₹20,000)
- Inline descaling cartridge before geyser inlet (₹2,000-₹5,000)
- Magnetic/electronic water conditioner (₹1,500-₹4,000)
💡 Investing in water treatment pays for itself within 2-3 years through reduced service costs and extended geyser lifespan.
