15L — The Right Size for Indian Families
15L gives 10-12 minutes of hot shower for 3-4 people — enough for a family. Smaller 10L models need reheating between showers. For a family of 4+, 15L is the minimum.
5-Star BEE Rating — Real Electricity Savings
A 5-star geyser uses ~15% less electricity than a 4-star model. For daily use, that's ~₹500-800/year savings. Over the 8-10 year lifespan, it pays for itself.
Hard Water Resistance — Critical Spec
Indian water has high mineral content. Feroglas/glasslined tanks + magnesium anode rods prevent scaling — the #1 cause of geyser failure. Check if your area has hard water before choosing.

FAQ
Q1. Is 15L enough for a family of 4?
Yes — 15L gives hot water for 3-4 consecutive showers. For larger families, 20L is better.
Q2. What's the electricity cost per shower?
A 2000W geyser uses ~0.5 kWh per shower — roughly ₹4-5. 5-star models reduce this by ~15%.
Q3. Do I need a voltage stabilizer?
Not usually — modern geysers handle normal fluctuations. Only needed in areas with extreme voltage swings.
Q4. How long does a geyser last?
8-12 years with proper maintenance. The heating element may need replacement after 5-7 years.
Q5. Which is better — 5-star or 4-star?
5-star saves ~15% electricity. Over 10 years, it saves ~₹5,000-8,000. Worth the small price difference.
Q6. Can I install it myself?
Not recommended — professional installation ensures proper pressure fitting and safety valve setup.
Q7. What's the difference between storage and instant geyser?
Storage = tank heats and holds water (10-30L). Instant = heats on demand (1-3L). Storage is better for families.
Q8. Does hard water damage geysers?
Yes — mineral scale builds up on the element and tank. Choose models with feroglas/glasslined tanks + magnesium anode.
Q9. Best geyser for hard water areas?
Venus MegaPlus or Havells Greta Pro — both designed for hard water.
Q10. Do I need a separate bathroom fitting?
Yes — the geyser mounts on the bathroom wall, connected to water inlet and shower outlet.
