Water Heater(Geyser) Buying Guide

What Is Heater/Geyser?

The water heating unit or geyser is a machine that creates a heat transfer process using the energy source. The energy source is used for heating water above the initial temperature. 

Typically, the water heater is used for domestic usages like cleaning, cooking, shower bath, and space heating. In various industries too, water heaters have got multiple usages in terms of steam.

Different Types Of Geyser Or Water Heater

The following are the various types of water heaters – 

● Electric Water Heater

Best Water Heater In India 2023 - Reviews & Buyer’s Guide 11

An electric water heater works just like the standard water geyser that you have seen or heard about. It would bring cold water from the dip tube and then try to heat it using the electric heating element present in the storage tank. 

Here the hot water would rise in the tank, and then it is moved into the home using the heat-out-pipe. 

Gas Water Heater

Best Water Heater In India 2023 - Reviews & Buyer’s Guide 12

A gas-powered water heater takes the cold water brought into the tank using a dip tube. This water is then heated using a gas burner. 

The burner would burn the gas, thereby releasing extremely hot and toxic air right up through the chimney present in the middle of the water heater storage tank. The chimney would move the toxic air outside while the chimney’s metal is heated that ultimately boils the water.

Here the energy is transferred to the closed-loop system, and this should contain the heat conductive material that would heat the water present in the tank. So, this can save a lot of money right on the sunny days and would work particularly better for those living in warm and sunny climates. 

But such water heaters would need a backup plan like electricity and natural gas. So, this type of water geysers would continue to run even on cloudy days.

Storage Water Heaters

It would be wise to keep in mind some aspects while purchasing the best geysers in India.

The major ones are –

► Capacity

Always think about the household usage of the hot water that you want. Here this is what determines the capacity requirements of the water geyser you need. Now for a single person or any nuclear family, you would have to go with the smaller tank water heaters. 

There is another factor you might have to take into account. Does the water heaters have both usages in the kitchen and bathroom? Or should you install them individually at each of the locations?

In areas where there is extreme winter, you would have to go with a water geyser with a larger capacity. 

► Material

Now when you live in areas where they are getting hard water, you need to pay special attention to the tank and even the heating element material. So, when both of them come into direct contact with the water and even hard water, there would be a high magnesium and calcium content, leading to building up or scaling. 

Frankly, this can lead to decreasing the efficiency, corrosion, and shorter lifespan of the heater. You might also better check out for a corrosion-resistant water heater that is reliable, efficient, and even long-lasting. 

► Heating Element

One of the major necessary things to look for in any of the water heaters, especially in the electric storage water heaters, is whether the tank would directly contact the water or not. 

Now, if you have hard water at your home, then the water heater tank would be more prone to scaling and corrosion. Most people don’t know that hard water has a high concentration of minerals. These are usually magnesium and calcium, which would make the inner tank corrode faster. 

So, you must check out the quality of the tank just before purchasing it and even make sure that it is an anti-corrosive powder coating tank. Here, it is equally necessary to check whether the heating element used right inside the water geyser is resistant to corrosion. 

► Insulation

For a high energy-efficiency of the water heater, the heat that is created by the heating element should be inside the tank. It must be for a longer period. Now it is the poor insulation among the tank and the water heater’s outer body that would lead to high power consumption. So, one needs to make sure that the water heater’s insulation material is of high quality.

► Wattage

According to the Energy Star program, BEE (Bureau Of Energy Efficiency), they rate electric water heaters right on a scale of 1-5. Here the more stars, the more energy-efficient the water heater is. So when you purchase the water heaters, check for bee rating.

In most cases, the water heater’s wattage would not be the right aspect to consider when evaluating power consumption. Rather the necessary aspect is to consider the amount of hot water used and the standing loss (the heat loss from the sides, top, and bottom). The standing loss is the major factor that increases the power consumption of water heaters. The water heater’s time to raise the water temperature by a particular degree is another major factor.

► Build Quality

When you live in an area that is getting hard water, you need to pay special attention to the tank and even the water heating element material. 

Here, both of them would contact the water and even the hard water with a high content of calcium and magnesium. These would be leading to built-up and scaling. Also, this can lead to the decreasing of corrosion, efficiency, and a shorter lifespan. 

► Electric Consumption

When installing the water heaters, you would know that it would increase your power bills a lot. The power consumption of the water heater is based on various factors. The first one is the volume of the water used. 

So, here if more hot water is consumed, electricity consumption will be more. Another aspect to be considered is the temperature of the input water. If you live in colder places, you need more heating effects than people living in a warmer climate. 


Some of the major features of the best water geyser in India are – 

● Automatic Shut Off

The water heater’s automatic shut-off safety valve helps detect the leakage as early as possible, and it would allow the flow to be stopped. The better part is that some of the automatic shut-off safety valves can contain a disconnect for the power. It would mean that there would be a huge difference between repairing the leak and replacing the water heater. 

Here the idea would be to place the device at a location that can measure small amounts of water and even turn off the flow just before any serious damage happen.

● BEE Star Rating

Suppose you check the BEE rating or star level. In that case, it refers to the grade of the standing loss that is commonly displayed on the electric water heater label. You might see it among the minimum and the maximum that is five stars. 

● Fuel Or Circuit Breakers

Most of the water heaters, especially the electric geysers, might use the directly immersed heating element to heat water. The best water heater would have this heating element controlled by a microprocessor control module or a simple thermostat. 

Now they would make these materials in the form of heating elements that can affect one’s option and output. So, the voltage or wattage of a good water heater and the storage water heater capacity are some of the major options you would like regarding the fuel or circuit breaker. 

● Fire-Retardant Cable

Nowadays, most electric water heaters have fire-retardant cable, and this would resist the combustion and even the propagation of the flames when there is a fire.

● Flame Failure Protection

This feature is used to avoid the basic buildup of huge amounts of gases when the pilot system goes out at the gas heater. Most of the famous brands like Havells and Racold use this. Here You would do it from the arrangement of the coil, thermocouple, and valve. Some of the latest gas heaters would be having a default timer that would be around 15-20 minutes.

● IPX4 Protection

The water heater would have a safety system that protects against all kinds of dry heating, over-temperature, over-pressure, and even various kinds of electricity leakage. Much of the water heater brands would have this feature to secure the water seepage from the protection’s IPX4 level.


Nowadays, most water heater manufacturers would provide a six to ten-year warranty on their product. Even the heating element and thermostats would have a certain warranty and help the tank fail in the first six years. 


The price at which you choose the water heater is an important factor. Most of the water heaters are available at a low and discounted price, and they would be based on one’s needs and necessity.


When you are purchasing a water heater, always go for the branded ones. They provide a good warranty and have great features.
