Best water heater in India 2023 – A Buying Guide

Choosing water heater is not much of a problem if you go for the brands which are well-known for quality and services they deliver. Nevertheless, there is awesome competition between these brands which is directly reflected both in their utilitarian and technical product designs. They always plan their offerings for specific segments of this market and see to it that they do not shake the confidence of their customers and thereby compromise their own interests.

Therefore, you have considerable options to choose from. We are trying, here, to help you get the best geyser in India 2023.

Instant Water Heater

Best Instant Water Heater

Which geyser is best for you largely depends on the way you prefer to take bath and the amount you need. If you use bucket bath, then you need instant geyser; if you use shower bath, you need storage water heater.

By the way, shower bath is recommended because fresh water constantly flows on your body making it easy for you to remove dirt from your body. Since the dirty water also constantly drains away, your skin doesn’t retain dirt. It is more hygienic. However, you cannot enjoy it in winter unless you have a storage water heater installed in your bathroom.

The advantage offered by the instant geysers is altogether different. They are usually small in size and compactly designed. They offer higher wattage than storage heaters in order to deliver properly heated water instantly.

If they deliver high wattage, it doesn’t mean that they are not energy efficient. Unlike the storage water heaters, they don’t have to turn on and off in order to maintain temperature of the water. They spend their energy once to heat water that is needed on-demand and to be used instantly.

Technology Considerations

There are different types of geysers, offering different levels of functionality and facilities that not only make taking bath a joyous experience but also safe and cost-effective. These functional elements owe themselves to different technologies that are employed for the purpose. Therefore, we now proceed to consider the tech-specs of the two main types of water heaters, namely, instant water heater and storage water heater.

There are also heat pump water heaters and solar water heaters. But they are beyond the scope of this brief buyer’s guide.

Types of Instant Geysers – Condenser & No Condenser Geysers

The geysers that feature condenser are to be preferred to those that come without it; because the condenser makes them more efficient.

The geysers featuring condenser have two metal heat exchangers which are usually made of stainless steel. The second heat exchanger is introduced in order to save the heat of the flue gases from being wasted and preheat the incoming cold water. This results in energy saving up to 90%!

The heat exchanger is there in place of a tank in order to deliver water on-demand. Water is not stored in a tank. Stored water loses energy. To maintain such energy loss, the storage heaters have to keep on turning on and off. Therefore, they use more energy than the instant geysers.

This also explains why the non condensing geysers cannot match up with the condensing geysers.

Safety Features

While buying instant water geyser, you must look after the following safety features:

  • Thermostat cut-off: It addresses the issue of short-circuit incidence by automatically switching off the device
  • Thermal cut-off: It comes into operation when heating reaches certain level
  • Anti-siphon system: It wards off backflow of water
  • IPx4 protection: It makes the device waterproof

Most heaters now come with the facility of automatically switching off when any safety-related issue crops up. Mostly, these issues have to do with overheating, dry heating and overpressure.

To make it plain for you, all you need to look out for is a term ‘three-level’ or ‘four-level’ or ‘multi-level’ or ‘IPx4’ safety system.

The Storage Water Heaters

Best Storage Water Heater

This type of water heaters are meant for consumption of large quantities of water in a cost-effective way. They come with storage tanks with different holding capacities. It is for you to decide whether you need 25 liters or 15 liters or 10 liters.

Normally, storage heaters use natural gas, propane, fuel oil and electricity. Here, we are limiting ourselves to electric storage water heaters.

These are electric convection heating appliances. They store up energy in storage elements during the time of a day when charges per unit are quite low compared to the time when they are high. Then, as per your requirement, they release the heat during on-peak tariff periods. This is the mechanism that makes it cost-effective.

But the downside is that storage water heaters do leak heat which, in technical terms, is called standing loss. It necessitates them to turn on automatically to keep the water hot at the temperature that you have set. In spite of this the advantage that accrues from their drawing energy for storage during the off-peak periods is not small. It does significantly lower your utility bills.

Another advantage is that storage water heaters remain full because cold water enters the tank from its bottom so that the hot water is released from the top of the tank.

The down side of storage heaters is that, if not enough energy is stored and the next day turns out to be chilly or if more than enough is stored and the next day is a bit hot, then in either situation you are not going to enjoy your bathing experience.

Vertical or Horizontal Storage Heaters

It is said that vertical storage heaters are more energy efficient than the horizontal. However, the major difference that marks the two types lies in the functionality that is offered to come to terms with an incidence that in technical terms is called turbulence. It takes place in the water tank where the cold and hot water meet.

As it is, due to less density the hot water remains on top and the cold water at the bottom. This is called stratification. Where these two meet, there takes place turbulence. It is less in vertical geysers than in horizontal storage heater.

What’s more, horizontal geysers are costlier. You go for it only if the roof of your bathroom is low.

Storage Tank Technology

This plays very vital role in storage heaters. It is usually made from three different elements:

  • Copper
  • Stainless steel &
  • Thermoplastic

Different manufacturers use different materials to line this tank in order to make them durable. Some use superior quality polymer for coating the tank. But more often than not glass is used for the purpose. And, in order to avoid heat loss, PUF is introduced between the wall of the tank and insulation.

Glass is good for stopping corrosion from taking place in the tank. This does not mean that tank will not rust. It will; but depending on the quality of the glass lining, the process of corrosion is slowed down considerably. Again, the glass they use in order to line their tanks also vary.

There is another technology that is commonly used in the tank of storage water heaters. It comes in the form of anode rod that consists of different materials. Normally, it is made of Magnesium, Aluminum, & Zinc

The function of the anode rod is to save the storage tank from rust. If you are living in areas where water is hard, then it is good that you ensure that the water heater you use features aluminum anode rod. But if the water is soft, then better go with the one that has magnesium rod.

Efficient Inlet Water Diffuser in Storage Tanks

This innovation is quite interesting and works by diffusing the water that vertically enters into the tank into smaller streams in horizontal directions. This function significantly minimizes the turbulence that occurs at the time of mixing of hot and cold water.

Heating Elements

As the name suggests, these perform the task of heating operation. Their efficiency largely depends on the materials used in composing them.

  • Incoloy: It is made from nickel, iron and chromium to resist high temperatures, oxidation and corrosion
  • Nichrome: It is composed of 80% nickel and 20% chromium. This, too, is quite effective in resisting high temperatures

Heating Controls

These could be

  • Automatic
  • Manual
  • Power switches
  • Thermostatic controls &
  • Intelligent controls that not only control temperature settings but also tracks your usage pattern. They are also enabled with preset instructions to follow. So when you need, then only it delivers hot water; when you don’t, it doesn’t. You can use them by connecting them to your smartphones through app

Fitness for Installation in High-Rise Buildings

It is measured in MPa, that is, megapaschal pressure. It is also called bars. The more bars the product offers, the more capable it is to resist pressure. For multi-storey buildings 8 bars pressure resistance is required.

If you are not staying in high-rise building, then 6 or 6.5 bars would suffice.

Safety Features

Most of the part these are offered as

  • IPx4 protection: Makes the device waterproof
  • Multi-function safety valve (MFSV): Safeguards you against high pressure with a pressure valve, flowing back of hot water into cold water pipeline with a non-return valve, built up sediments with a drain valve and vacuum relief valve
