Faq's
- What does a 5-Star BEE rating actually mean for a water heater, and how much can it save me?+A 5-Star BEE rating signifies that the water heater has minimal standby heat loss, meaning it keeps the water hot for a longer time after being switched off. This efficiency can reduce your electricity consumption specifically for water heating by 20% to 50% compared to a non-rated or lower-rated geyser, leading to significant savings on your monthly electricity bill.
- Are 5-star water heaters suitable for high-rise apartments or buildings with pressure pumps?+Yes, all the top 5-star storage water heaters, including the models listed above, are typically rated for an 8 Bar working pressure. This high pressure tolerance makes them perfectly suitable for high-rise buildings (generally up to 30-35 floors) and homes utilizing pressure booster pumps, ensuring the tank can safely handle the increased water pressure.
- Which component is most important for a water heater’s longevity in hard water areas?+The most critical components are the inner tank coating and the anode rod. Look for advanced coatings like AO Smith’s Blue Diamond or V-Guard’s Titanium Enamel. Additionally, a sacrificial magnesium anode rod (often extra thick) is vital, as it chemically protects the tank and heating element from corrosive scale build-up caused by mineral content in hard water.
