Instant vs Storage Geyser: Which One Should You Buy in 2025? 

Are you uncertain about the ideal type of water heater? An instant geyser is suitable for occasional use, while a storage geyser is preferable for families and frequent use. Compare the most popular water heaters from both categories, such as those made by Haier, Havells, and AO Smith. India primarily has two types of geysers: instant and storage, which serve various household needs. Families or individuals seeking a constant supply of hot water during the winter would find storage water heaters ideal. Instead, instant water heaters are more efficiently adapted to the smaller spaces, less frequently used, and less expensive, which is why they are ideal to use in a kitchen or a second bathroom. Storage geysers are used to heat and store water in the internal tank of the geysers, which are generally offered in 15L to 25L with storage capacity and are becoming a very common purchase in Indian houses. Instant geysers are ready to supply hot water almost immediately and are most suitable for use in households when it comes to washing dishes or short-term use. The type, capacity, and price range of some of the best-selling and highly rated geysers in India (2025) available on the Amazon website were taken into consideration.
