🏆 Why 5-Star BEE Rating Matters
Lower Electricity Bills
5-star rating means maximum energy efficiency – uses least electricity to heat water. Perfect for daily use – save ₹100-150 per month on electricity bills!
Better Insulation
High density PUF insulation keeps water hot longer, reducing reheating frequency. 5-star geysers maintain temperature better than lower-rated models!
Environmental Friendly
Using less electricity means lower carbon footprint. 5-star Otto is the eco-friendly choice for environmentally conscious buyers!
