Best Electric Geysers in India - Reviews and Comparison 2021

Geysers are of three types- gas, solar and electric. Electric geysers are further divided into two i.e. storage and instant.

• Storage geyser

Storage geysers come with a water tank that can store water in high capacity. Once the heater is switched on, the stored water heats up and stays at a set level using a thermostat.

The water tanks used in storage geyser is either made of stainless steel or copper. Steel tanks last longer and need less maintenance; however, copper tank outperforms the steel one. Under storage type, you get different capacities models ranging between 6 litres to 35 litres.

• Instant geyser

As the name suggests, instant geysers give you hot water in no time. They don’t come with additional storage tanks. The instant water heater does not heat water continuously as in the case of a storage geyser. Once an instant geyser is switched on, water is heated and delivered fast, and heating stops immediately after use.

Copper and stainless steel are the two common material used in making geyser tanks. Thermoplastic is also used to create a water heater tank; however, this is not a common material.

Copper: Copper is the best build material due to its high heat conductivity. Copper is a good conductor of heat, and it raises the temperature of the water faster. On the negative side, the copper tank is prone to corrosion and needs a lot of maintenance.

Stainless Steel: Stainless steel tank is commonly used in water heaters. They have coatings of anti-corrosive powder and glass linings. Besides, steel demands less maintenance and provides better insulation.

Thermoplastic: The uncommon thermoplastic tanks are corrosion resistant but lack insulation.

The capacity of a water heater matters a lot, and it entirely depends on the number of family members and their purpose. For instance, if around 4-5 members need a continuous water supply to take a shower, then get a geyser with at least 25 litres storage tank. A small and instant geyser can meet the hot water needs of a small family.

For quick analysis, refer to table.

Anti-corrosive and anti-scale nature of tank matters because not everywhere people receive soft water. Hard water has the potential to completely corrode the tank’s metal and give room to calcium scales. This results in a short lifespan of a geyser and low heating efficiency.

There are several ways to make a tank corrosion resistant. Different types of anti-corrosive coatings like glass linings, porcelain enamel glass, vitreous enamel, blue silicone enamel, titanium are used by manufacturers to make a tank corrosion-free.

Most manufactures use glass coatings alongside steel-based alloys for best insulation. If your geyser has a magnesium rod in the centre, the problem of corrosion is less likely to occur. To reduce the chances to zero, use a water softener.

It is very crucial to find out how much power your geyser consumes else you better get ready to pay a heavy electricity bill! The best way to find out if your geyser is energy efficient or not, check its BEE rating. All the electric water heaters have it; otherwise, you can use the following formula to find out power consumption.

Power units consumed = Water volume x Temperature difference x Electricity costs

Some other factors that influence the electricity consumption of the heater are:

Initial water: During the cold season, the temperature of the input water is low, and the geyser consumes more energy to heat up the water.

Water quantity: This is quite simple. More water needs more heat and for a long duration. This eventually consumes more power.

Thermostat setting: The thermostat option lets you set a specific temperature. Once the heat reaches that temperature, the geyser turns off on its own, saving power.

Heat retention: This is another simple point. If your geyser retains heat for a long time, the less energy it will consume.

The importance of the heating element is at par with the tank material. Manufacturers usually use copper heating elements with anti-corrosive coatings. Better geysers have glass-coating heating elements as this provide better resistance against corrosion. These elements are stronger than we think they are. On the one hand, copper can face hard water for up to two years, and on the other hand, glass coating can last for four years.

If your apartment is in a high rise building, then you might know that high-pressure pumps are used in apartments for supplying water to every flat. If the water entering the geyser have the same high pressure than it can cause leakage or tank burst. However, the water pressure inside the geyser depends on the tap providing water to the geyser and the expansion of water inside the heating appliance. This pressure is measured in bars. So, if your geyser has more than 6 bars, it can take high water pressure otherwise water can leak, or the tank can burst. Glass lined coating helps here as well as the coating is ideal for resisting not just corrosion but high pressure as well.

Insulation helps in draining the energy and improving the water heating process. Thicker insulation ensures low heat loss. Therefore, an extra layer of insulation is always beneficial. Fibreglass wool is the most common insulation type used in electric geysers. However, if your geyser has PUF (polyurethane foam), that is even better because it has a more extended water retainment capability and helps you by saving 40% more energy.

After the tank material and heating element, next in the queue is the outer material of the geyser. This has to be of superb quality as well. Like tank and heating element material, variety is not used in making the body of a geyser. Almost all geyser manufactures use ABS plastic for making outer body material. High-grade plastic is an excellent choice as it doesn’t corrode and also it leaves a large room for manufacturers to design a geyser well.

BEE star rating is vital to consider because it will tell you how much energy the geyser uses. All manufacturers have an obligation to put a BEE star rating label on their box. A geyser with a higher star rating will cost you more but save your electricity bill in the long run. A 5-star rating geyser is unbeatable, but a 4-star water heater is also good enough.

The feature is relatively self-explanatory. To prevent overheating of water, modern geysers come with a function that lets you set the temperature. Once the geyser reaches the desired set temperature, it turns off automatically.

The flow rate of water is also known as Gallons-per-Minute or GPM. It helps in measuring how many gallons of water can come out of your kitchen or bathroom tap or bathtub per minute. The flow rate usually remains 3 per minute in case of a tap and 7-8 minutes in case of a shower. An instant water heater with 3 litres capacity is ideal for tap flow rate, and a storage geyser with a larger capacity should be used for the shower.

Most electric geysers, especially high capacity water heaters, consume 2000 watt of power. Whereas, instant geyser mostly operate at 3000 watt and therefore, it draws a lot of power in a short time.

Durability is essential for a geyser to perform efficiently, and it very much depends on the quality of material used to make the tank, outer body and heating element. And having an anti-corrosion rod is like a cherry on the cake. A few other factors which increase the durability of a water heater are safety features like thermal cutouts, fire-retardant wires and safety valves.

Electrical water heaters either have vertical or horizontal mount type. Amongst these two, vertical mount is the most common type. Horizontal heaters, also called H-wall geysers, are still new in the market as they are most preferred in homes with low ceilings, false ceilings or attics. A vertical mount heater calls for at least 2 feet of space to fit.

Just like in the case of any other product, brand matters while buying electric geyser as well. A brand ensures you that the geyser is qualitative, has all the useful features, comes with an extended warranty and exceptional customer service. Some of the famous electric geyser brands in India are Bajaj, AO Smith, Havells, Crompton, V-Guard, Longway, Racold, Usha.

Additional features never harm, in fact, extra function like good design, adjustable knob gives a wholesome experience and makes things more convenient. For example, our body doesn't need water with a temperature exceeding 50 degrees Celsius. Therefore, the feature of customised heat temperature adjustment comes in handy.

For excellent after-sale service, buy from a brand. A brand might have multiple service centre, and one can be near your home as well. If that's the case, you can get your geyser fix anytime. Otherwise, a good brand takes responsibility for its product, so even if it doesn’t have a service centre nearby, you can always seek help from customer care.

Unlike gas geysers, electric geysers come with long term warranty and different years warranty on different parts. The high brand gives around a 5-years warranty on the water tank and two years warranty on heating elements and other components. Comprehensive warranty or the overall product warranty against manufacturing defects also remains of 2 years in the majority of cases.

Usually, an electric geyser price range remains ₹ 6,000 - ₹ 12,000. However, the cost can go below or higher than this in a few cases as per the storage capacity, BBE star rating, brand name, etc. There are so many types of geyser available in the market from several brands that we are positive whatever be your budget; you will not have to compromise on your requirement.

• Avoid using copper chambers electric geysers at places where high-pressure water supply pumps are used because that can damage the geyser in the long run.

• Keep the cut-off at 60˚C for an electric geyser. It prevents overheating in the absence of user surveillance.

• Try to buy a geyser with BIS/ISI mark. This ensures that the product has undergone the required quality checks.

• Keep the children away from the geyser when it is switched on.

• Keep other electrical appliance in the bathroom off when the geyser is on.

• Regularly flush out the scales and sediments to prevent high electricity consumption.

• Use an exhaust fan while using the geyser. The hot water creates mould due to moisture which can damage your bathroom.

• While installation, makes sure that there is enough space between the apparatus and the walls. Also, the water heater should be easily accessible in case you want to set the temperature, or need to get it repair.

• Install the geyser at the height of at least 1.8 metres from the floor for right water pressure and a strong hot water flow.

• Electric geyser is a high power consuming appliance. Therefore, connect it to a Miniature Circuit Breaker (MCB). It will minimise the chance of a short circuit in case of power fluctuations.

• Do not keep the geyser switched on for a long time as that reduces the life of the apparatus. Switch it on just 5 minutes before you need it and not half an hour before.

• A lower temperature setting helps you save electricity. Lower temperature means the geyser will have to work less due to which it will consume less power.

• The anti-corrosion anode rod inside the tank doesn’t let rust and other impurities present in the water settle on the tank. However, to protect the tank, it rusts away in a few years. Therefore, check the anode rod every three years. If the outer layer of magnesium has corroded away or 6 inches of the inner steel core is visible, that indicated the rod needs replacement. A few other indicators for rod replacement includes rod coated with whitish calcium sediments or reduction of thickness to below half an inch.

• Check the working of temperature knob/settings and pressure release valves once a year. The checking process is easy. All you have to do is release the pressure a couple of times. And if you want to remove the valve in case of leakage then first drain some water from the geyser and remove the discharge tube.

• Your plug needs a regular check as well. The use of low capacity wiring for the power socket leads to spark now and then. Also, there could be burn marks on the plug pins due to burning from higher electricity. Such acts can cause a short circuit in the long run. Therefore, use a new plug and socket. Also, use an MCB switch instead of a regular one. Another thing you can do to prevent any kind of burn is switch on the water heater only when you need it and switch it off immediately after use.

• Use metal inlet and outlet pipes rather than plastic pipes as metal is more resistant to heat. Also, check the joints from time to time. If there are whitish deposits from hard water or rust around the joints, replace the pipe.

Our comparison winner is an electric geyser with 25 litres storage capacity. Bajaj has a reputation in the Indian market when it comes to home and electric appliances. We were sure that our selection is not wrong, and more than 6,000 positive reviews only backed us up. The geyser is available in 10 and 15 litres storage capacity as well.

Bajaj New Shakti Storage is perfect for a medium to large size family. It can fulfil all their needs from primary to secondary. With 43.3cm length, 44.1cm breadth X 57cm height, the size is relatively compact, and you can fit it anywhere. And it is a durable geyser so by storing 25 litres; there are no performance issues.

As we mentioned earlier, the material of the tank, heating element, outer body contributes to the lifespan of a geyser. So, if the tank is made using a material that keeps corrosion at bay, then you are going in the right direction. The inner tank of this Bajaj geyser has a glass-lined coating which minimises the chances of corrosion and rust. Also, the presence of magnesium enhances the protection against corrosion and leakage.

Safety features are essential, and Bajaj knows that too. Therefore, the geyser is equipped with a heap of safety measures to prevent overheating, dry heating and excess pressure. Additionally, the cable extension of the geyser is fire-retardant as well.

Despite offering so many powerful features and such large storage capacity, it consumes a reasonable amount of power- 2000 watt and has a 4-star BEE rating.

AO Smith is a US-based company; however, their products perfectly meet the needs of the Indian audience just like this electric geyser.

The colour and design of SDS-Green Series-015 make it stand out among its competitors. We really admire the compact size and sleek design as they can complement any interior.

AO Smith is known for using innovative technology, and in this geyser, it has used Blue Diamond Glass-Lining technology which provides corrosion resistance two times better than any other. It is a bit pricey than other geysers on our list; however, the use of such advanced technology lower down the maintenance and running costs. Besides the Blue Diamond tank, the anode rod with a steel core of stainless steel also protects the tank from hard water.

Apart from hard water, other things that can affect the performance of a geyser is the building up of scales and sediments, but with the glass-coated heating element, you need not worry even about that.

SDS-Green Series-015 is ideal for a family with 2-3 members, and if you have more needs, you can pick its 25-litre package. Furthermore, the water heater is perfect for a high rise apartment as it can manage a pressure of 8 bars.

The geyser is reliable in terms of usage. The safety valve releases air pressure, discharging the water and preventing accidents. Another safety feature tat the geyser comes with is auto-shutoff. Further, the temperature control knob lets you adjust the temperature from 25℃ to 75℃ easily.

Along with the price, the BEE star rating is also on the higher side - a 5-star rating. On the contrary, the power consumption is on the lower side with only 2000 watt.

V-Guard is known for delivering the best inverters in India. However, we believe, by providing such fantastic geyser features, the brand will soon get its position in the water heater market as well.

V-Guard Victo has an elegant design that sets it apart from other water heaters. In fact, due to the white colour, it will make a bathroom or any space look polished. And due to the temperature control knob and indicator lights on the front panel, it offers convenience. Apart from this, the geyser has 4- star BEE rating, and it is available in 10, 15 and 25 litres storage capacity. Our review is on the 15-litre tank.

V-Guard geyser can stay in your room for a long time thanks to the high-quality mild steel outer body, which also has an anti-corrosive powder coating. It can smoothly withstand the humid bathroom environment. As tank material also matters in increasing the life of a geyser, so we took that too into account. Thick-gauge steel using single-lined welding technology has been used to make the inner tank. And the superior glass-lined coating provides further protection against corrosion happening due to hard water.

The geyser is safe to use as it comes with a four-layered safety system- thermal cut out, thermostat to precisely control the temperature, the multifunctional valve regulating pressure control and magnesium sacrificial anode protecting the tank from corrosion.

Racold Pronto Neo is a 6-litre instant geyser. If we had made a buyer’s guide solely on instant geysers, this would have been our comparison winner.

The brand says it is an Italy inspired and crafted design with a rare combination of technology and style, and we couldn’t agree more with them. Not just the design is elegant even the features with which this geyser come are remarkable.

The geyser’s capacity might be not much as compared to storage geysers, but it gives a tough competition to them with 6.5 bars of pressure. Therefore, this instant geyser is suitable even if you live in a high rise building. The insulation feature is equally vital. PUF Insulation technology has been used in it which retain internal heat and temperature and reduces power consumption.

The auto cutoff function further helps in saving electricity bills as the geyser turns off when the desired heating temperature is reached. The safety valve further ensures safety as it stops the pressure from getting unbearably high. The anti-siphoning system prevents the back flow of water and dry heating makes this geyser more reliable.

Being a 6- litre instant feature, a medium-size family can use it for washing hand and dishes in the kitchen. For the bathing purpose, it is suitable only for 2-3 persons. It is also available in 1 and 3 litres capacity.

With Havells Monza EC 10, we are providing you with a review of a 10-litre capacity geyser. However, you can also get 15 and 25 litres capacity tank in the same model.

Havells is a renowned name in the electrical market. It has never compromised on the features even in that market, nor it has done it here. The water heater tank has been made using the best technology-  Feroglas, which has a glass lining protecting the tank from corrosion. To protect the tank from scales and sediments, the geyser has a heavy-duty anode that balances the pH levels  of water.

The geyser comes with an efficient temperature knob, and you can choose the settings from 25°C to 75°C. Havells water heater is suitable if you live in a high rise building as it has 8 bar pressure. Moreover, it has a stainless steel braided flexi pipe, making it ideal for both cold and hot water passing.

On top of it all, the water tubes using Whirl Flow Technology helps in saving energy. The technology prevents any direct contact between cold and hot water, thereby promoting fast heating and 20% more hot water output.

We have another entry from AO Smith-HSE-VAS-X-025. This is a 25-litre storage electric geyser which is also available in 15 litres capacity.

HSE-VAS-X-025 has also used Blue Diamond Glass-Lining technology in making its tank, which reduces scaling and enhances the durability of the tank. It provides twice the corrosion resistance and strength of the tank. The heating element is made up of a customised alloy which also protects against corrosion. Lastly, the glass coating on the element ensures uniform heating and continuous water supply.

Just like SDS-Green Series-015, it also has a 5-star BEE rating and the advanced PUF insulation technology helps you in saving power by leaving no gaps between the tank and insulation.

The design has not been compromised in this model also. You get a sleek design with a thermostat feature.

Our last water heater is the second instant geyser on the list. Although it has promising customer reviews and ratings, however, our reason for putting it in the last spot is only two years warranty and less storage capacity options. Crompton Bliss is available only in 1 and 3 litres.

If you can ignore those two pints, the geyser has everything to offer. It has superb heating speed due to  a 3000-watt heating element  made out of high-quality copper. The body material is also strong enough to protect the geyser from rusting. The  stainless steel body retains heat and multiplies the heating element’s performance.

The brand has not cut corners in terms of safety. You get a precise thermostat, a thermal cutout, and a reset knob. Moreover, the anti-siphon protection technology prevents the backflow of water and dry heating. At such a low price, the water heater is equipped with even LED indicators  that inform you when the water is ready to use.

If budget constraints are there and you need a geyser for primary purposes like washing hands and utensils, Crompton Bliss is the right fit. Checkout reviews, features, buying guide and comparison of best gas geysers in India.
