And that’s why this section is helpful for those who want to know how to decide the best geyser. To make it simpler, we have broken down the process into 5 easy types.

Step 1. Choose Your Purpose

It is always good to know why you want to buy a geyser. Depending on the no. of family members and the use, you can roughly find what type of water heater you want and how much should be its capacity.

This step will help in narrowing down the search to a few options. Below we’ve given a table for your reference:

Step 2. Choose Your Type

In the above step you found out the capacity and the type of water heater you may need. In this step we will see how many types of geysers are there and what are their main features.

Depending upon the technology, Geysers/Water heaters can be divided into three types:

  1. Electric Water Heater
  2. Gas Water Heater
  3. Solar Water Heater

1. Electric Water Heater/Geyser

By their names you can guess that they run on electricity to heat the water. They are easy to install and are used by most of the people. Due to their compact and sleek designs they can be installed anywhere in the house.

Electric water heaters are also further divided into two categories:

  1. Instant Water Heater
  2. Storage Water Heater
A. Instant Water Heater

These water heaters heat the water instantly. But they come in only 1 & 3 litres versions. Due to the lack of storage, they are more compact than the Storage Water Heater and can be mounted on the wall easily and without acquiring any extra space.

They can give the hot water immediately upon starting. They are also cheaper than the Storage Water Heater.

Who should buy the Instant Water Heaters?

If you want to buy a water heater for Kitchen uses then it is a perfect option for that. It can also be bought if you have a small family of 1-4 family members and prefer bucket bath.

Showering will not be possible using the Instant Water Heater. Also, if your area has the problem of frequent power cuts, then it is advisable to not buy the Instant Water Heater.

B. Storage Water Heater

These water heaters store the water and heat them depending on their storage capacity. They come in 3, 6, 15, 25+ litres versions. Due to the storage feature they are bigger in size than the Instant Water Heaters and require more space for the installation. 

Upon starting you may have to wait for up to 5 minutes to get the hot water.

They also keep the water hot for a certain period of time. Due to their advanced features they are more expensive than the Instant Water Heaters.

Who should buy the Storage Water Heaters?

If you have a family of 3+ family members and prefer to shower bath, then this type of geyser is perfect for your use. You’ll just have to choose the capacity according to your family size.

They are also recommended for those people who experience frequent power cuts in their area or they live in areas with very low temperatures. 

2. Gas Water Heaters

These types of water heaters use gas for the heating of water. They are connected with the LPG gas connection of the house or a separate gas connection.

They are cheaper than the Electric Water heater and they also provide instant hot water. Due to less technologies they are lighter than the Electric geysers.

Why are they not recommended?

Many experts believe that the Gas Water Heaters are dangerous to use without proper precautions. As these geysers run on LPG, they produce Carbon Monoxide gas.

If this gas is inhaled by any person in excess then this can cause even death. Also, there’s always a  possibility of gas leakage from them.

Due to it’s unsafe nature we don’t recommend Gas Water Heater to anyone.

3. Solar Water Heater

These types of water heater are powered by the sunlight. Due to their large size they can only be installed on roof-top. They are economical in the long run and don’t need any special maintenance once installed.

As they run on sunlight, there will be no dependency on the gas connection or any type of electricity.

While they are a good option if you have a high budget, they cannot be installed in apartments or rented places. Also, they can become ineffective during Monsoon and winter due to lack of sunlight. 

Who should buy Solar Geysers?

If you have a large family and a slightly higher budget then you can install them on your roof-toops.

While there can be some problems if enough sunlight is not provided, some of the solar geysers come with gas or electricity as a backup option. 


Step 3. Choose Brand

water heater brands are important factor

Many people buy Geysers/Water Heaters from local brands, and when some problems occur after purchase they experience zero after sale service and no warranty. This can cost extra money in the long run.

There are many benefits of buying geyser from a popular brand like:

  • Good after sale service.
  • Extended warranties on the product.
  • Availability of spare parts in the market if needed.

Here, we are listing some of the popular brands in the Indian market which provide good quality water heaters:

Havells, Bajaj, Crompton, AO Smith, Racold, V-Guard, etc.


Step 5. Important Features To Look For

Now, after following all the steps above, this step will help you in buying the best geysers with the latest safety features. These are some of the essential features which must be present in a good water heater.

1. Auto Thermal CutOff

This is a safety feature which stops the water from overheating which if not present can damage the heating element of the geyser.

It cuts off the power automatically when a desired temperature is reached and prevents any further damages. This feature is present in all of the popular geyser brands in India.  

2. Safety Valve

This feature prevents any excess pressure build up in the geyser due to heating of the water.

If anyhow a high pressure starts to build up then it releases it to the outside which can prevent any damages to the water heater.

3. Power Consumption

power consumption is also important for the geysers

As geysers are a daily need in winter seasons and in cold areas, they must be efficient enough to consume reasonable power. You can check the efficiency of a geyser by its BEE Rating.

These star labels are issued by the Bureau of Energy Efficiency (BEE) for the electrical appliances, which is an agency of the Indian government.

The more stars are there, the more efficient the geyser will be in consuming electricity. That’s why, try to buy a 5 star rating geyser, which will help you in the long run.

4. Warranty

warranty is an important factor for water heaters in india

As geyser is an expensive home appliance, you should always look out for a geyser with good no. of years in the warranty.

If possible, you can also take extended warranties which will help you to use geysers for a good 5-8  no. of years without any major problems.

5. ISI Mark

You should always buy a geyser/water heater with an ISI mark on it. It signifies the quality and safety of the product.

If it’s not present, then it’s better to not buy it, as it can be dangerous to use a geyser without an ISI mark.

6. Hard Water And Soft Water

hard water is not good for inner tank of geyser

If your area has hard water then it is best to choose a Water Heater with a corrosion resistant tank and Blue glass coating.

This is because hard water has calcium and magnesium salts which start to deposit in the inner tank. This causes damage and the geyser becomes inoperable in a very short period of time.

You can also use a water softener which will convert the hard water to soft water and then supply it to the geyser.


Immersion Rod Water Heater – Geyser Alternative

While geysers are always a better and more convenient option, you can also use Immersion rods. They are a cheap and good alternative for simple uses.

With a good immersion rod you can heat water to it’s boiling point in less than 10-15 minutes.

It is a good option for Kitchen uses and bucket bathing. For people having hard water in their area, they can also use immersion rods for their daily uses.

FAQs – Geyser Buying Guide India

Which is better instant or storage geyser?

Well it depends on how you want to use it and how many members are there in your family.

For Kitchen purposes Instant geyser is best. But if you want to use it for bathing then, a storage water heater will be the best choice for you.

What happens if the geyser is left on for 24 hours?

If the geyser is left on for 24 hours then, it can explode due to dry heating and overheating.

That’s why most modern geysers have an auto cut-off feature which automatically turns off the geyser after the water is heated to the set temperature.

For how many years does a water heater last?

If the geyser is of good quality, then it can last up to at least 10-12 years. For a geyser to last more than this, you should always provide it with good quality water because hard water shortens the durability.

Also, you should regularly provide its servicing for maximum efficiency.

Can I install the geyser myself?

We don’t recommend this unless you are a professional. As a proper installation of geyser requires safety measures which must be followed for prevention from any damage.
