Not only this, but the big problems come into the picture when all these brands promise to produce the best instant water heater. At that moment, It might get tough for you to make the decision.

To make your life easy, we have created this buying guide where we will be discussing various important factors that you must consider while buying the best instant water heater in India.

Factors to consider while buying the best instant water heater in India

1. Size

The size of the water heater plays a very important role as different sizes are available in the market for different kinds of requirements. This feature accounts for the capacity or the water the heater can uphold for your immediate use.

The best instant water heaters that are discussed above as you must have seen have 1 litre to 3 litre and straight 10 litres.

Usually, a 1 litre water heater comes into use for a single person, and for families of good 3 – 4 people, the water heater of 3 litres is required.

A few water heaters also have a capacity of 10 litres which can be used for huge and joint families.

A 1 litre water heater is most likely to be used at the washbasin and to really have a bath and it cannot provide you with the continuous stream of hot water.

But water geysers ranging from 3 liters to 10 liters can be easily used for literally anything in the house, be it washing dishes, bathing, or washing clothes.

2. Geyser Wattage

This is said to be the second most important feature that needs to be checked before you buy a water heater. The instant water heater usually has a standard wattage consumption of 3000 Watts.

Few of the instant water heaters consume upto 4500 Watts but they also tend to deliver better performance.

3. Bar Pressure

The pressure of the water is measured in bars. It can be said that bar pressure is the pressure with which the water will be heating the tank. The tank should be strong enough to withstand the forces of water and not get crushed under it.

This pressure usually varies from place to place and from height to height. The pressure on the ones living on the top will be lesser than the ones living on the ground.

If the walls are thin they might get damaged under the high pressure of the water. An 8 bar pressure tank is an ideal one and is recommended if you live in a high rise building. If you have an independent house you can always go for the one with 6 or 6.5 bar pressure.

4. Tank Material

You must check the material the tank has been made of. This is because it will reflect upon the durability and efficiency of the geyser in the long run.

Generally, a water heater is made of stainless steel, copper, or even thermoplastic. So, let’s talk about all these material individually, so you have a clear vision as to what you should go for.


Copper as you already may know is a quite good conductor of heat and electricity. But the drawback here is that the rate at which the water cools down is also faster than others. We can say that copper tanks have a very low heat retention capacity.


Thermoplastic tanks work the best with an inner coating on the walls. These walls usually are corrosion resistant but the heat retention property is low. And thus, the inner coating on the wall is required.

Stainless Steel

Stainless steel is one of the best materials that can be used in the making of a tank. It is better from both copper and thermoplastic.

This is because of its great insulation and heat conduction is quite durable and quite corrosive too. This can be easily overcome by the usage of a corrosion-free technology.

Coating of Tank Material:

  • Glass – Lined Coating :

Copper and thermoplastic can be coated by a glass lining. It maintains water temperature. With regular usage, this may get damaged in the long run.

  • Vitreous Enamel Coating :

It is usually used for stainless steel because of its great resistance abilities to prevent corrosion.

5. Heating Element

The usual heating element used needs to prevent the material from corrosion. It is generally a copper heating element that has a coating. The glass-coating is used as the heating element as it one of the best to prevent corrosion.

It is considered to be a bit expensive though but assures a long life to the appliance. It can last upto 4 years. Another can be the glass-coated copper as the heating element that can work wonders and is not very expensive too. It can last upto 2 years.


6. Power Consumption

An energy-efficient water heater is what you should strive for. It will reduce your bill as well as is beneficial for the globe. The energy star rating of the water heater usually determines it’s energy efficiency.

The ones with 5-star ratings are the best. Higher is the rating given by BEE (Bureau of Energy Efficiency) the lesser will be the consumption of the power. This in turn also increases the life of the Instant water heater.

7. Hardness of Water

The hardness of water is a thing that is taken lightly by many but is as hazardous. It is harmful for your skin, hair, and many more appliance like the water heaters. Hard water has calcium and magnesium salts which damage.

The heating element and can abrupt the working of the water heater. It is really important for you to choose a water heater that can withstand hard water. Such a water heater has a corrosion-resistant water tank. These tanks are either lined with glass or are Vitreous Enamel coated.

In case you live at a place where hard water persists throughout, the best option would be to buy a water softener. This will serve as a softener and would reduce the effect of hard water on the heating element. Thus, would save it from getting damaged.

8. Fuel Type

Most of the Instant Water Heaters have commonly two fuel types, electrical and gaseous. It can be considered a bit tricky to used the gas geyser in India.

Thus, most of the instant heaters mentioned above and in the industry are usually electrical and reduce the power consumption of it too.

9. Price

You should buy any appliance that has the quality as well as that matches your budget. For that, we would like to tell you that the price of an instant water heater usually ranges from 2000 to 3500.

The ones with high capacity usually cost more than those which have less capacity. The material used inside the geyser also plays a huge role in setting the prices of the appliance.

10. Warranty

Something that you should keep with yourself your whole life is the warranty. The longer the warranty period the better the offer is for you. Instant Water heaters are quite prone to damage and thus, a warranty is a must thing for you.

Many brands offer a warranty period of 4-5 Years while some give for 2-3 years. As already mentioned the longer the better. Some brands offer special warranty on the exterior body and the interior tank.
