3-Star vs 5-Star Geyser Comparison: Power, Efficiency & Savings Explained 

A 5-star geyser is much more efficient than a 3-star geyser because the former uses less power and it heats up much faster in a more stable manner. Customers are able to compare related products from brands like Havells, AO Smith, and Haier which ensure safety, durability, and excellent energy efficiency, thus saving them in the long run. It is crucial to choose an effective and trusted water heater in India that will allow you constant access to warm water in the winter and will not turn into a waste of electricity that is used unnecessarily. 

The BEE star rating indicates the energy efficiency of geysers, with a 5-star water heater consuming significantly less power than a 3-star model, which helps reduce long-term energy expenses. Although the price of a 5-star geyser is higher, it is much more reasonable, as the latter is more insulated and has further developed heating devices, energy-efficient systems, etc. Their stability, quick heating capacity, and low electricity costs make 5-star geysers a wiser option than 3-star water heaters. The following is the list of some of the best 5-star water heaters in India from reliable brands like Havells, Haier, AO Smith, V-Guard, and Bajaj.
