Published 25 January 2023

Whether you live in the chilly hills of Himachal Pradesh or the tropical coasts of Kerala, a water heater is an essential home appliance. With many models from many brands to choose from, it can be cumbersome to find the right water heater for your needs.

So, this practical guide from HNK will walk you through everything you need to know about buying a water heater in India.

Understanding Water Heaters

Before beginning your search for the perfect water heater, consider your specific needs.

First, take into account the number of people in your household and how frequently hot water is needed.

Next, consider the capacity that best suits your daily hot water usage.

Finally, don’t overlook the importance of energy efficiency, as an energy-efficient model can save on electricity bills in the long run.

Types of Water Heaters

Storage Water Heaters

Storage water heaters come in a range of capacities, typically between 6 to 35 litres.

These are suitable for larger families that require a continuous supply of hot water. They generally consume more electricity and need more space.

While they offer the benefit of providing hot water whenever needed, it’s essential to choose models with a BEE 5-star rating for energy efficiency.

Safety features such as safety valves and thermal cut-offs are also crucial in storage water heaters.

Instant Water Heaters

If you’re looking for a quick heating solution, instant water heaters might be the choice for you.

These are designed for small families or individual use, usually holding 1 to 3 litres. Instant water heaters consume less power compared to storage types and are ideal for providing hot water quickly.

However, the limited capacity means they might not be suitable for households requiring a constant supply of hot water.

Gas Water Heaters

Gas water heaters, with capacities ranging from 6 to 10 litres, operate on LPG or natural gas.

They heat water faster and are more economical in terms of energy consumption. However, they require proper ventilation and regular maintenance.

Gas water heaters are an excellent option for those looking for an efficient and cost-effective solution but bear in mind the maintenance and installation requirements.

Solar Water Heaters

For the environmentally conscious, solar water heaters offer an eco-friendly option.

Utilizing solar energy makes them highly efficient, and while they can be economical over time, they have a higher initial cost.

Solar water heaters depend on sunlight, so their effectiveness might vary with the weather and location.

What to Consider When Buying a Water Heater

Regional Climate

The local climate plays a significant role in choosing a water heater. In colder regions, you may require a heater with a higher capacity.


Balancing the upfront cost and long-term energy savings is crucial to stay within budget without compromising on quality.

Energy Rating

When shopping for a water heater, it’s essential to consider the BEE (Bureau of Energy Efficiency) rating. The higher the stars, the more energy-efficient the appliance.


A thermostat feature will allow you to set the desired temperature, making usage more convenient.

Safety Features

Safety features like auto shut-off, safety valves, and thermal cut-offs should not be overlooked, as they can prevent accidents.


Consider the installation requirements for different types of heaters, ensuring proper ventilation for gas heaters and sunlight for solar models. 

Warranty and After-Sales Service

Choosing models with an extended warranty provides peace of mind and ensures long-term satisfaction with the product. Check for reliable customer support and after-sales service in your area to avoid future hassles.
