Water heaters/ geysers are simple devices that convert electrical energy into heat energy with the help of a heating element in the appliance to provide you with hot water. With advanced technologies and features, modern water heaters have learned to withstand problems such as high water pressure, corrosion and saving energy. With variable sizes, designs and shapes available in the market, it is a matter of choice as to what kind, purpose and price you wish to look at.

Now, investing in the right water heater is important in order to make the most of it. Some might find it daunting to purchase a water heater without burning a hole in the pocket. Fret not, this comprehensive list brings you the best geysers/water heaters available in India to help you with making a choice. Still, confused with deciding the right kind? We present you with a solution for that too.

Scroll through our “Water Heater Buying Guide” to get an inside out information about choosing the right geyser for your home.

Quick Note: Make sure to check the water (if it is soft or hard) beforehand. If the water supply is hard (contains more salts), then ensure the geyser you purchase comes with the corrosion-resistant tank. Or else you can install a water softener to convert hard water into soft. Because hard water affects the heating element and diminishes the life of geyser.

Buying Guide – Water Heaters

When purchasing any home or kitchen appliance, it is very important to have proper knowledge of how to analyze the features and choose the best according to your requirements. Without this information, you can end wasting your money on the unsuitable water heater.

Below, we have briefed all the information required to analyze a geyser. Read it carefully to choose wisely.

1. Know Your Purpose

The main reason for the purchase of a geyser is the first important thing to consider – as it helps you further choose the type of geyser suitable for you. For example, A small geyser is sufficient to use in kitchens for hand wash and cleaning utensils while big sized geysers are used effectively in bathrooms. So, it’s important for an individual to take a wise decision before purchasing water heaters. Some of the questions you have to ask yourself are…

  • Are you purchasing the geyser for washing kitchen utensils?
  • Should the geyser be compatible with showers?
  • Do you want a geyser just to connect with a normal tap in the bathroom?

Questioning yourself helps to analyze what your requirements are.

2. Water Capacity/Heater Size

It is hard to pinpoint on the right water heater capacity as it depends on the number of people and the consumption rate. The purpose of your buy also makes a valid addition in deciding the right water heater for you.

A 10-15 litre capacity water heater is ideal for a family of 4. Similarly,  if you are looking for an instant geyser for kitchen utility, a 3-litre water heater would be recommended. Thus, depending upon the purpose, consumption and the number of users, here we give you a small table that paints a picture on this issue.

Size of Family Purpose Geyser type Capacity
2-3 members kitchen instant 3-litre
2-3 members bathroom storage 10-15 litres
4-6 members kitchen instant 3-litre
4-6 members bathroom storage 25 litres

Once you have decided on the capacity of the water heater, the next step is to choose the type of water heater.

3. Types of Geysers

Based on their working principle, geysers are categorized into two – electric and gas. Let’s have a clear description of each type in detail…

a) Gas Water Heaters/Geysers:

As the name suggests, LPG cylinders are used as the energy source for heating water. They were popular a few years back for its economic advantage but it is strictly not recommended any more due to the obvious safety reasons. Gas geysers are in general instant geysers. All the more, they are not available in larger tank capacity.

b) Solar geysers:

economical, efficient and highly reliable, solar water heaters are the future of water heating. However, they work out only if you are living in an independent house and are ready to invest in a large capacity tank. Solar geysers do not work out for apartments/flats or other commercial buildings. With initial investment forming a dent in the pocket, they are worthwhile only for 50-litre tank and more.

c) Electrical geysers: compact, energy-efficient and durable, electrical geysers are the best choice for small families living in apartments. Available for decent prices, these geysers are reliable with exceptional safety measures. Although it is all in all dependent on a power source, once heated, they hold the capacity to retain the heat within the tank. They can also work under high water pressure.

Now, based on the storage type, water heaters can be classified into

  • Storage water heaters: These water heaters are always stored with some water depending upon its storage capacity. Under sufficient power supply, the water stored in the tank heats up to the required temperature and even retains the heat after cutting off the power source. Although electricity supply and the bill might be an issue, all the water heaters nowadays are energy efficient and require low maintenance.
  • Instant/Tankless water heaters: These heaters are tankless as the name suggests. They are required to be connected to the water supply constantly. On your requirement, you just have to switch on the power/gas and let the water heat up for a few seconds. These geysers generally have a small heating capacity. It might require you to wait for a few minutes for the water to flow from the tank/tap, heat and then outflow.

Instant Geysers Vs Storage Geysers

Instant Geysers don’t have separate storage tank capacity like storage geysers. In instant geysers, once you switch on, the water is heated quickly and delivered, and once you switch off, it will stop heat water immediately. If you want hot water again, then you have to again switch on the device. However, when it comes to storage geysers, once you switch on certain amount of water (depending on water tank capacity) water is heated and thermostat controls the water temperature for few hours, even after you switch off the device.

Let’s have a brief comparison of these two types in the below table…

Feature Instant Storage
Space requirement Narrow space Larger surface
convenience Not for showers Ideal for showers/washing
Time required Hot water supply within a few seconds Requires anywhere between 10-25 minutes
Cost Rs 6-8k Rs 7-10k
Available size 1-3 litres 6-35 litres
Shelf life Longer than 10 years except for a few miscellaneous changes Up to 10 years with little or no maintenance

4. Power Consumption

Electrical water heaters add up to 15% of your monthly electricity bill depending upon the weather conditions and consumption. Although most of the household appliances are energy-efficient, it is still essential for you to understand the amount of power your water heater consumes in order to make some savings.

All the branded water heaters are BEE rated. Look at the BEE label and study the annual power consumption in units. You can then cross-check that with this simple formula

Units consumed = Water volume X Temperature difference X Cost of electricity.

Other than this, there are a few factors you have to consider deciding the energy consumption of the water heater.

  • Input water: The rate of heating depends of the initial water temperature which will change with the season, also the power consumption.
  • Purpose of water: needless to say, the purpose of water usage plays an important role in energy consumption. The large quantity of water requires more power.
  • Thermostat setting: all the modern electric water heaters come with a thermostat that lets you set a temperature which is further maintains using the auto on/shut off feature.
  •  Auto-off- a geyser with auto-off feature shuts the device off after reaching the desired temperature which prevents unnecessary power consumption.
  • Heat retention: although most of the modern heaters do come with this feature, this is a less significant feature deciding the efficiency of the product. The more the heater retains the heat, the less power it consumes.

5. Tank Material

The material from which the inner tank is built matters a lot! Not just to prove its efficiency but also to ensure a safe water output. Tanks are generally built using the following materials:

  • Copper: Although these tanks are obsolete nowadays, it was one of the most used materials to build tanks for water heaters. Copper is a good conductor of electricity. This ensured a quick response in heating the water. However, it also causes corrosion and loss of heat putting the safety of the water in question. Also, it requires regular maintenance.
  • Stainless steel: Commonly used in most of the modern-day water heaters, stainless steel tanks are usually coated with anti-corrosive powder and glass lining to keep the tank free from corrosion and other electrochemical reactions. The insulation is better and also requires little to no maintenance.
  • Thermoplastic: A lesser-known material for a tank. However, thermoplastic tanks have a better non-corrosive feature when compared to copper. On the downside, they are not insulated.

6. Heating Element

 The heating element is also as important as the tank material. Most brands make copper heating elements with a coating used to prevent corrosion.  Some manufacturers use glass coated heating element, they are considered to be the best in resting corrosion and the most expensive ones. Another popular heating element is glass coated copper heating element, they are not so expensive but are quite good.

7. Anti-scale and non-corrosive feature

Since India has a hard water supply, when the water is exposed to certain heat for a prolonged period, there tend to be some electrochemical reactions happening in the tank. The calcium carbonate in the water forms limescale deposits in the tank as a side effect. This might harm the purity of the water, obstruct the function of the heater or even harm the device. This buildup will cost the consumer more as the tank needs to be changed in order to get the water heater back working. Thus, it is important for one to consider the make of the tank and ensure that it is coated with anti-corrosive powder/lining.

8. Mount

Vertical mount water heaters are the most common type of heaters found in the market. Horizontal heaters called H-wall water heaters are a new entry to the market that are suitable for areas with low ceilings, false ceilings or attics. Make sure your bathroom/kitchen has about 2 feet of space to fit a vertical mount water heater.

9. Water pressure

It might sound insignificant but it does make a lot of difference especially if you are staying in a high rise building/apartment. The water pressure in the tap that feeds the heater should be checked. An ideal water heater with more than 6 bars can withstand high water pressure. Any lower than that, leakages and tank bursts can be expected. Most of the modern-day geysers come with a safety valve to depressurize the water within the tank by releasing some amount of water. Other than that, glass lining and magnesium coated anode rods help in maintaining the water pressure.

10. Build and Material

Now that we know the importance of the material used in building the inner tank, let us look at the limitations set in building the outer body. Not to mention the importance of design and look. With most of the inner tanks built with stainless steel and coated with titanium, enamel and glass lining to provide insulation, the outer body can be built using plastic. However, sturdy material such as ABS is preferred. The plastic even helps in moulding the heater to the desired shape and design.

11. Appearance and Design

Though appearance and design are two least considerable facts to some customers there are always some hidden benefits to consider them when buying any electric household device. Like an attractive geyser can complement your bathroom colour and decoration. If it is well designed then it can also save wall space, especially when you have smaller bathrooms.

12. Rating

Star rating is something one has to consider in order to save money and time on a long run. All the water heaters are marked with a BEE star rating by the Government of India. Higher the number of stars (on a scale of 5), the more energy-efficient the device is. Always consider buying any home appliance with 4 or higher star rating.

13. Wattage

An average water heater generally works at 1500 to 2000 W A/C power while some manufacturers have increased it to 2500-3000 W. An instant water heater can draw an enormous amount of electricity over a very short time, they can work at 3000 W and sometimes 45000 W. Again a geyser with high flow rate such as 100L/ hour will consume more power than those with lower flow rates.

14. Additional Features

It is always good to have some additional features like good design, adjustable knob and others to make the bathing experience even more convenient. Our body cannot handle too hot water, so you don’t require hot water that exceeds 50 degrees Celsius. That is why it is better to have customized heat temperature adjustment in a geyser. This will prevent the struggle of mixing hot and cold water to get desirable hotness. And moreover, it saves electricity bill as well.

15. Durability and Maintenance

The durability of water heater represents the ability to withstand and function effectively even in unpleasant conditions. The durability of the geyser ensures long-lasting nature without any damage to the product. Moreover, the maintenance of the geyser depends on geyser type and frequent usage. To maintain geyser in good working condition, clean the tank once every week to prevent from rusting.

16. Geyser Brands

There are plenty of brands in the market manufacturing geysers- you can find one that costs1000- you can also find one that costs 10,000. No, we are not telling you higher price always comes with greater benefits but why there is so much difference in the price? Why brand matters so much?

Well, most of the time price does make a difference in terms of quality, durability and reliability. Paying some extra bucks for a branded geyser will always pay you back. A good brand geyser with good hardware quality always ensures safety, whether it is gas or electric. There are very rare cases of gas leakage or short circuits. It saves electricity consumption thereby saving your monthly electricity bills. A reputable brand comes with a warranty and ensures you don’t pay for a new geyser every year.

Our advice will be to always look for a geyser that has ISI marks if you want to reduce you geyser maintenance cost. Any geyser without ISI mark will increase the cost of its spare parts including the heating material, thermostat and service cost.

17. Warranty

It is always best to have a long warranty period when it comes to geysers. Usually, most of the high brand water heaters have 4 – 5 years of warranty on the water tank and 2 – 3 years on the body and other accessories. As geyser is not a small investment, we recommend preferring high warranty periods.

18. After Sales Service

Geysers are one of the important household appliances, so when you buy a new one it is always advisable to buy from a reputable brand which offers quick repairs and replacements in case any damage occurs.

19. Budget-friendly Nature

Finally, we end up buying a guide with the price. Though it comes last in the list, you should take into the count as you may strict to your budget low or high. If you’re on low-budget, go with the entry-level models that best matches with your heating or storage requirements. Otherwise, go with top-notch water geysers that come at expensive rates.
