Best Geyser/Water Heaters In India – Buying Guide

You must check out every aspect of the geyser to get one that fully satisfies you. Hence, we’ve compiled everything necessary that you need to know with the help of our experts.

Different types of Geyser /Water Heaters

The types may initially seem confusing. There are two primary ways water heaters are categorised. Some are categorised through their energy supply, while some are done so through their storage capabilities.


Types of Geyser / Water Heaters depending on Energy Source

There are three types of water heaters based on energy sources. They are Electric Water Heaters, Gas Water Heaters and Solar Water Heaters.

1. Electric Water Heaters

Electrical Geyser

Electrical geysers work by turning electric energy into heat energy. They make use of heating elements to increase the water temperature. A few of these heaters also come with intelligent features like temperature adjustment, automation and time delays.

If you’re living in a rented house or an apartment, then this would be the perfect option. These geysers heat to temperatures higher than that of Gas heaters.

Advantages of Electric Water Heater

  • Compact size.
  • Easy installation and maintenance.
  • Budget-friendly.
  • Excellent for home use.

Disadvantages of Electric Water Heater

  • Inoperable during power cuts.
  • Wiring load capability can affect heating.
  • Highest operational costs among all types.


2. Gas Water Heaters

Gas Water Geyser

These water heaters work using natural gasses like LPG (Liquid Petroleum Gas) or propane gas.
They can heat water much faster in comparison to their electric counterparts.

If you’re installing a gas water heater, make sure to fix the device behind the LPG gas cylinder to provide gas through the pipelines.

Gas water heaters generally make water instantly with no forms of storage, like a tank. They’re a good fit for the kitchen, as that’s where you’ll keep a gas cylinder. However, if you’re going to install into it into the bathroom, keep the cylinder outside for safety. After all, as gas cylinders emit carbon monoxide fumes, ventilation is essential.

Compared to electrical heaters, these actually have a far cheaper operation and maintenance cost. But, the installation can be a hassle, as they take a lot of space and need separate gas connections. They can also be a safety hazard if they’re not made of high-quality materials. Generally, Gas geysers don’t last more than 6-7 years.

Advantages of Gas Water Heaters

  • Don’t get affected by power cuts or voltage fluctuations.
  • Due to more energy availability, water heats up faster.
  • Operation and maintenance costs reduced to a great extent.
  • No wastage of hot water or energy, as the water doesn’t get stored.
  • As the hot water comes heated from a continuous source, there’s a larger supply of hot water.

Disadvantages of Gas Water Heaters

  • Dangers of gas leakage and carbon monoxide poisoning.


3. Solar Water Heaters

Solar Water Geyser

If you live in an open area, then solar geysers can be beneficial. These use energy acquired from sun rays through solar panels. The energy turns into heat, which then gets sent to the water tank to heat the water.

With these heaters, you can save up significantly on money, electricity and gas. Though initial cost might be higher, it all pays off in the long run. Like all good things do. Although, if you don’t live in an independent house and rather live as a tenant, then this won’t work right for you.

The best water heaters to go for in this case would be the solar heaters that can use electricity or gas as a backup.

Advantages of Solar Water Heaters

  • Environment friendly.
  • Saves money.

Disadvantages of Solar Water Heaters

  • Most expensive among other types of heaters when it comes to upfront costs.
  • Work in very specific places and situations, ineffective in monsoons and winters.
  • Only available in large capacities, so only fit for large families.

Types of Geyser / Water Heaters depending on Storage

Based on storage, there are two types of water heaters. They’re Storage Geysers and Instant Geysers.

1. Storage Geyser

Storage Geyser

Storage Geysers have the highest capacity, as they come with water tanks that can reserve water for specific periods. Once the heater turns on, the reserved water heats up and stays at a set level using a thermostat.

Most of these water heaters have two kinds of water tanks- some have stainless steel tanks, and others have copper ones. Steel tanks are expensive in general, but they last longer and need less maintenance. Copper tanks are even more so, as they work much better.

There are models with various capacities, so you can get something that suits your needs. For instance, small families can have an adequate supply with a 20 Litre capacity. Though, for bigger families, 25L-35L capacity is the best choice.

Advantages of Storage Geyser

  • Most affordable.
  • Need minimal maintenance.
  • Store large reserves of water.

Disadvantages of Storage Geyser

  • Stored water loses heat after some time.
  • Water needs to be re-heated continuously, which wastes energy.


2. Instant Geyser

Instant Geyser

Unlike Storage geysers, Instant ones don’t come with additional storage tanks. Moreover, while Storage geysers heat water continuously, Instant ones operate differently. Once an Instant heater turns on, water is heated and delivered fast, though it will stop heating immediately after use.

Though these are said to heat water up instantly, it might still take some time if there’s more distance between the heater and the tap.

Advantages of Instant Geyser

  • They take up less mounting space.
  • Immediate heating of the water coming from the outlet.
  • Ideal for kitchen utility washing and hand wash.
  • Very energy efficient.
  • Suitable for nuclear families.

Disadvantages of Instant Geyser

  • Are more expensive than storage ones.
  • Installation can be tricky.
  • For bigger families, you might need more than one.

Things to consider before buying the Best Geyser In India

There is a multitude of things you need to need to know to find the best geyser in India and choose what fits you well. Each heater has its own shortcomings, and this guide will help you look out for what you need to get the performance best for you.

1. Capacity

Geyser Capacity

If you’re going to use a continuous water supply, for things like long baths and showers, then go for geysers with storage tanks.

On the other hand, for a medium-large family for about 4-6 members, a 10-15 Storage tank would be the best.

A small family has a much more different ideal choice. A 3-Litre Instant water heater would be best suited to the family.

Here’s a table to help you find the capacity you need, with all the essential factors.

2. Water Tank Material

Water heater tanks are usually made of materials like copper, thermoplastic or stainless steel. They help the heater generate more heat while still keeping a safe output.

Copper: A lot of the water heater tanks use copper as the build material. That is because of its heat conductivity. As copper conducts heat well, the heater can raise the temperature of the water faster.

Copper Geyser Tank
Copper Geyser Tank

Though, the efficiency gets lost in time, as corrosion can occur. Besides, there’s also a lot of maintenance necessary.

Stainless Steel: They’re just as common as copper, and you’ll likely find them in most modern water heaters. Stainless steels have coatings of anti-corrosive powder on them, along with glass linings.

Stainless Steel Geyser Tank

This way, the tank stays safe from corrosion along with other electrochemical reactions. Moreover, the insulation is better, and you need to put in much less maintenance.

Thermoplastic: This tank material is much less common. Though it offers protection against corrosion, which copper doesn’t, it still lacks insulation.

3. Anti Corrosive Design

You’ll be using the geyser regularly, so its crucial to check if the water tank of the geyser you’re going to purchase is anti-corrosive or not. This step is especially important, as in some part of India, water is terrible.

Hard water can easily corrode, building up calcium scales in the water tank. As a result, you will be notice lower heating efficiency. In fact, you might have to replace the heater once a year.

Manufacturers use anti-corrosive coatings to solve such problems. Most of them use glass linings, but some also use porcelain enamel glass, vitreous enamel, blue silicone enamel, titanium and several other materials.

Glass coatings provide the best insulation, alongside steel-based alloys. They’re also less corrosive, maintaining original surface for a long time. With magnesium rods at the centre, the heaters can be even more effective in keeping the corrosive salts at bay. Just in case, you can also use water softeners to convert hard water to soft water, as this will fully take away the chance of corrosion.

4. Heating Element

Geyser Heating Element

The heating element is as vital as the tank material. Most brands use copper heating elements, with anti-corrosive coatings on top. A few manufacturers use glass coated incology heating elements, which have the best resistance against corrosion.

Though, they’re also the most expensive. These elements can even withstand hard water, upto four years. Glass coated copper heating elements are also an excellent choice, they’re affordable and the best value for money. A heating element with only a copper coating lasts a mere two years in areas with hard water.

5. Wattage

Electric waters operate the best at 1500-2000 watts, most of the time. Some geysers come with a power of 3000 watts, meaning that it draws a lot of power over a short time. In fact, a geyser with high flow rates (100L/hr) can draw more power than heaters with lower flow rates.

6. Build Quality

We already know how important the quality of the inner tank material is. Now let’s talk about what kind of outer material you should look for. The outer part is made up of plastic.

However, that isn’t an issue as the best water heaters use ABS plastic as outer body material. This allows the heater to be sturdy while leaving it free to have a good design.

7. Insulation

Geyser Insulation

To reduce energy drain, geysers come with heat insulation. Moreover, the insulation also makes the heating process faster while maintaining the operating temperature.

The thicker the insulation is, the lower the heat loss. All geysers have different insulation ratings. However, for the best results, you should add extra layers of insulation outside the heater.

The most common form of geyser insulation is with fibreglass wool, fixed with straps or trap. Whenever the burner runs, the insulation stops combustion gas outflow and airflow.

Also, some modern geysers come with PUF (polyurethane foam). They can work even better than the glass wools, as they have a longer water retainment capability. As a result, this saves 40% more energy. Even better, there’s a lot of money saved because of that.

8. Electricity Consumption

All water heaters are BEE rated, look at the BEE label and study the annual power consumption. Afterwards, you can confirm the consumption with this formula.

Consumed units = Water volume x Temperature difference x Electricity costs

There are also a few other things that factor in with the energy consumption of the heater:

Input water: The amount of heating the geyser will do depends on the initial water temperature. Thus, during colder seasons like winter, there will be increased power consumption.

Water quantity: The more the water, the more the heat will need to spread. As such, the heating process will be longer and need more power.

Thermostat setting: Newer water heaters come with a thermostat, which you can use to set a specific temperature. Once the heat reaches that temperature, them machine will turn off on its own, saving power.

Heat retention: Heat can dissipate as the heater works. So, if power consumption is a concern, heat retention is essential. The more the heater retains the heat it produces, the less power it will use in making more heat.

9. BEE star rating

Geysar BEE star rating

BEE star ratings play a vital role in letting you know how much energy the geyser you’ll buy uses. As all manufacturers are obligated to include the BEE star rating for a product, you should find it on a label somewhere on the box. The higher the BEE rating, the higher the price and energy savings. It can save you a lot of money in the long run.

If you want to save some on upfront costs though, then 4-star water heaters are still good enough.

10. Water Pressure

If you live in a flat or on a multi-story high rise building, then you likely have a high-pressure pump. These are used to ensure water reaches every flat. If the water pressure inside the geyser gets too high, then that geyser might leak.

The pressure inside the geyser comes from the pressure the tap providing water has, alongside the water expansion inside the geyser itself. Generally, this pressure is calculated in bars.

Water heaters with more than 6 bars can withstand high water pressure. Lower bars may lead to the hazard mentioned earlier. Recent geysers have a safety valve that depressurises the water within the tank by releasing some water. Glass lined inner tanks also help, as they can resist high pressures.

11. Durability

Durability is crucial to the heater’s efficiency. As we’ve mentioned before, get the best materials for both the inner and outer portions of the geyser, to get the most durability. Having an anti-corrosion rod is also beneficial.

Besides, some of the best geysers in India also comes with useful safety features like thermal cutouts, fire-retardant wires and so on. These features will keep both the machine and the user safe.

12. Automatic Shut Off Feature

This automatic feature is especially important, as it can save you not only electricity bills but your skin as well. Most geysers come with an intelligent mechanism that lets you set a certain temperature. Once the heater reaches that temperature, it turns off automatically, thus preventing overheating of the water.

13. Brand

Brands are just as important as the product itself. A good brand will provide you with a long warranty, genuinely distinct and useful features and exceptional customer service. Make sure you learn about the major water heater brands, as they’re not something you hear about regularly.

14. After Sales Service

As we said before, the brand can have a large impact on the quality of the after-sales service. You’ll be needing the assurance, as you’ll be using the geyser frequently and it might need occasional checkups.

15. Warranty

Most premium water geysers come with 4-5 years of warranty on the inner tank, along with 2-3 years of warranty on the other parts. During this warranty period, if your product ends up malfunctioning, you can get it replaced or repaired without paying.

16. Price

A lot of the geysers have premium features and thus have a high price tag. You can bring the price levels up or down through the heater capacity, along with the type. So get whatever fits your budget, and your needs without compromising anything. For instance, if you’re a bachelor, you can save a lot of money by getting a 3 Litre Instant Heater.

Power Consumption of Geyser

You’re going to use the Geyser every day, or though that usage can be a little less often as well. Either way, your electricity bills are going to spike up. Here are the primary factors that can vary your electricity bills.

Factors affecting electricity consumption of Geyser

  • The more the storage, the more electricity your Geyser will use to heat the water in it.
  • Seasons can have a great impact on your electricity bills, colder water during winter would need much more heating, and thus more power.
  • Filled up storage can cause more power drain, because the water heater will keep running if there’s any water remaining in the tank. So, always be sure to turn it off.
  • The auto shut-off feature can change the electricity consumption, a running geyser will not only overheat the water but eat up a lot more power as well. Having the auto shut-off feature prevents this otherwise common problem from happening.
  • BEE ratings are vital and informative. The higher the star rating, the less the overall power consumption.

Safety measures to follow when using the Geyser

A geyser is an electrical machine, and not having proper safety measures can lead to disasters.

  • Don’t use electric geysers with a copper tank with a high water supply pump, as the pressure can damage both the geyser and the tank.
  • While installing a gas heater, make sure to place the LPG gas cylinder up. Keep it outside the bathroom with a proper leakage proof pipe. Because, the gas heater emits Carbon Monoxide gas, so proper ventilation is necessary.
  • Make sure the electric heater you purchase has an auto cutoff feature that prevents the heater from going past 60°. Anything further can make pressure build up inside and burst.
  • Don’t use other electrical devices around the geyser while it’s operational.
  • Keep kids away from the geyser, lest they burn their hands with hot water from it.
  • Take out ant sediments inside often, to prevent unwanted power drain.
  • Don’t keep the geyser running for a long time.
  • The temperature level the heater is running at can greatly impact energy consumption. For instance, setting the temperature to 50°C instead of 60°C can save you 18% more electricity.
  • Most geysers have their thermostats set to 60°C by default, so please be cautious when using yours. Such a high temperature can cause severe damage and burns to your skin. Always make sure you mix in some cold water with the hot water to take down the temperature.

Best Geyser In India – Frequently Asked Questions

What's the best temperature setting for a geyser?

You can’t set the temperature when it comes to instant heaters. However, you can set it with storage heaters using a thermostat. You must set the water beyond 50° as anything below that can get contaminated by bacteria. The ideal settings are 60°-65° during winter and 50°-55° during summer.

Why should I turn the geyser off when not using it?

You do it so save electricity. A geyser’s thermostat maintains its temperature at a set level. It turns the heater off once it reaches the set limit. However, it also restarts to heat the water back up to the right level. So, if you’re not using the heater and the water inside cools down, the thermostat will repeatedly turn the heater on and off.

As a result, you’ll end up consuming more electricity instead of saving any, so always remember to turn your heater off.

Can I get shocked as I bath?

First, you should always ensure you have the correct earthing in the house for all your electrical equipment. Then, get a professional to install the water heater for you. Wrong installation may lead to the electric current not isolating properly from the water. Thus, it will flow through the water and cause electric shocks.

Can I shower with an Instant geyser?

Using instant geysers for showering causes harm to your body. It delivers high-temperature water right away; the temperature cannot be adjusted. On the other hand, with a storage heater, you can set it to heat to a specific level, after which it turns off.

How does the auto cutoff system work in the geyser?

If you leave a geyser turned on by accident, without a water supply, it will keep heating. Once the coil temperatures reach a set cutoff point, the heating element overheats. This trips off the thermal switch, which then cuts off the power supply.

Is it alright if I install the geyser myself?

Unless you are a professional, it’s in your best interest not to do it yourself. We advise you not to ask a local plumber either, as they don’t follow safety measures and aren’t very professional.

The best thing to do is to seek out an authorised service centre. Most manufacturers will provide installation services for their items, some free of charge and some at a small cost. You should always buy other installation accessories if your heater doesn’t come with them.

Are there smart geysers available, and what features do they provide?

Some of the best geysers come with features that fit in with any smart home. You can control these geysers remotely, so you can set them on with your phone a few minutes before you head into the bath. Other times you can also schedule the heater to run at certain times, during your bath times, for instance.

Are noises normal with water heaters?

Yes, if you only hear a faint noise every time the water heater reaches the necessary temperature. But if you hear popping, hissing or other unusual sounds, you should get it checked.

The problem could be due to the presence of limescale deposits or sediment build-up inside the tank. Either flush the tank or check the heating element to get rid of the issue. You can also get it checked in customer service.

How should I know if my water heater needs a replacement?

You should check if your heater supplies sufficient hot water or is losing out the heat every few minutes. A steady supply of hot water shows that your water heater is still up for running for a few more years. But, if the temperature fluctuates or the water output has sediments, it’s time you change your water heater.

The water heater is leaking. What do I do?

If you notice water leaking from the pipes, inlet valve or bottom tank, then it’s probably time to get a replacement. If the water leaks from the top/inlet valve, that indicates installation issues, while leakage from the bottom means there’s a crack in the inner tank. It’s best if you use the product warranty and replace the tank or the water heater.

What can cause my heater to produce insufficient hot water?

If your water heater runs out of hot water quickly or produces lukewarm water, it could be due to two main reasons. For one, the heating element or thermostat could be burned out. Or else your inner tank must have gotten clogged with sediments and scale build-ups over the years.

Why does my heater release water?

Most modern water heaters discharge water often. They do that to maintain internal water pressure within the tank. A multifunctional safety valve helps keep the water pressure and temperature in check to prevent leaks and bursts.

My heater produces smelly water. What do I do?

Bad odour in water comes from sedimentation and limescale build-up. Besides, with heavy chlorination of the inlet water, unwanted microbes and minerals may grow within the tank. This could lead to even fouler smelling water. But, you can keep the tank clean and safe for use through regular flushing.

How long can a water heater last?

A water heater can last upto ten years, depending on the hardness of water, daily use, build quality, installation and maintenance.

Once a heater starts ageing, it will need a replacement soon. For instance, rusty water can produce rust everywhere in the heater, leading to damage over time. Sedimentation can make the heater start making odd sounds at the bottom of the tank. The build-up of sediment forms calcite which is also heated and re-heated often.

As a result, the heater starts losing its efficiency soon. Water leakage means there are not a lot of chances left to fix the geyser, though you can look for repairable loose connections, fittings and pipe leaks.



Getting the right water heater is quite a task, as a lot seem identical at the start. However, all of them have small differences that significantly impact a heater’s performance.
