A reliable water heater can make daily routines more comfortable, especially during colder months or in homes where a consistent supply of hot water is needed. Whether you’re upgrading an old unit or purchasing your first geyser, choosing the right model depends on factors such as capacity, energy efficiency, safety features, installation location, and household size.
Modern water heaters are available in two primary categories:
Instant Water Heaters, which heat water on demand and are commonly used in kitchens and bathrooms with lower hot-water requirements.
Storage Water Heaters, which store heated water in an insulated tank and are better suited for families or homes with higher usage.
In this guide, we compare seven popular geysers available in India, evaluating their capacity, safety features, energy efficiency, durability, and ideal use cases.

2. Is a 15-litre geyser enough for a family?

3. Which geyser capacity is suitable for a kitchen?
A 3L to 5L instant water heater is commonly used for kitchen applications.

Higher-rated storage geysers are designed to be more energy efficient, though actual savings depend on installation, usage habits, and maintenance.
