Buyer’s Guide – Features of Best Instant Water Heater

While buying an instant geyser, many factors come into play. These defining factors are very essential to understand and they help you to choose top quality instant water heater to meet your requirement.

1. Size of water heater

The appropriate size for the geyser should be the amount of hot water that you would need at once for immediate use.

The instant geysers are available in 1 to 3 liters size. You can also find a few with a capacity of 6 liters.

If you check online, most of the instant water heaters that are available offer a capacity of 3 liters. 1-liter capacity is not really enough to provide a continuous stream of hot water and is thus, not suitable for bathing. However, you can use it for the washbasin.

Here is a table that will help you analyze the quantity of water required that will be suitable for your family. Let’s have a look.

Thumb rule: Geyser capacity vs. Family size

Tank CapacityFamily SizePurpose
1 LiterSingles/Bachelors (1)For Washing utensils or face wash
3 Liters2 – 3 membersBucket bathing & washing utensils
3 Liters4 – 8 membersFor washing kitchen utensils or for hand wash
6 Liters2 – 4 membersBucket bathing & washing utensils

2. Wattage of the geyser

Another factor that helps in selecting the best geyser for your home is the geyser wattage. Since the water heats up quickly, the wattage of instant heaters is generally high.

They either come with 3000 W (3kW) or 4500 W (4.5kW). Instant heaters with 4.5kW heat the water quicker than an instant heater with 3kW.

Since the wattage is high, it means that the electric load is going to be high too. For example, in metro cities like Bangalore or Chennai, if all the houses in the vicinity use a 4.5kW instant heater, the load on the electric grid would be too high. This will eventually lead to tripping or power failure.

Thus, before buying a costly and high-powered device, you should always consider your surroundings and see if the transformer has the capacity to handle the load.

For India houses, 3kW geysers are an ideal choice as they don’t put an unnecessarily high load on the system.

3. Bar pressure

The water pressure in the water heaters is measured in “bars”. Hence, bar pressure means the water pressure that hits the water tank in the geyser or heater.

This pressure varies from building to building. For example, if you are living on the 4th floor of a four-storeyed building, the water pressure at your home will be lesser than for the ones living on the ground floor.

When the water pressure gets in direct contact with the inner walls of the water heater tank, there is a high chance that the inner walls get thin and damaged over a period of time. Sometimes, even water starts leaking from the geyser tank.

It is recommended to buy 8 bar pressure geyser for high rise buildings to get better results in water pressure handling.

For those living in an independent house can buy a heater with 6 or 6.5 bar pressure and the water pressure is a bit low for them.

4. Metal used for tank

The material with which the tank has been made decides the quality of the geyser. Its quality has a direct impact on the durability and efficiency of the geyser. Generally, the water heater tanks are made using copper, thermoplastic, or stainless steel.

Copper: Copper is a good conductor of electricity and heats the water quickly. However, the rate at which the water cools down is also quick. Thus, the heat retention capacity is low in the copper tanks.

Copper is not corrosion-resistant. This, it must be coated with a good quality anti-corrosive material.

Thermoplastic: The thermoplastic tanks are resistant to corrosion. However, heat retention property is a bit low. To keep the water hot for a long time, it requires an extra inner coating on the tank walls.

Stainless Steel: It is considered as the best material when compared to both copper and thermoplastic as steel offers great insulation and heat conductivity properties. It is durable too but a bit corrosive. However, you can overcome this issue by using a corrosion-free technology.

Tank Material Coating:

  • Glass-lined coating: This type of coating is done on either copper or thermoplastic material to maintain the water temperature for a long period of time. With persistent use, there are chances that this insulation can get damaged in the long run.
  • Vitreous Enamel coating: This coating is recommended for a stainless steel water tank as it offers great resistance against corrosion. It also prevents hard water scaling.

Note: Every company has its own patented name for the tank materials. So, don’t get confused because they all are more or less the same at the end of the day.

5. Coil (heating metal)

The heating element is as important as any other factor. Most of the brands use copper heating elements with a coating to prevent the material from corrosion. Some manufacturers even use a glass-coated Incoloy heating element as they are considered as the best in the market to prevent corrosion. They are expensive though and can last for around 4 years even with hard water as a source.

Another option is the glass-coated copper heating element that works well and is not that expensive. The copper-coated heating element can last for around 2 years even when used with hard water.

6. Energy efficiency

Rather than falling for the marketing gimmicks, you must buy a water heater that is energy-efficient.

The energy efficiency of a water heater is generally determined by the energy star rating (heaters with a 5-star rating are considered as the best).

Higher the BEE (Bureau of Energy Efficiency) star rating is lesser the power consumption will be. This will, in turn, increase the lifespan of the heater.

7. Hardness of water at home

As we all know that hard water creates scaling inside the water tank of the geyser, this leads to the damage of the heating element too. Because of this, the corrosion happens faster and you might have to either repair your geyser frequently or buy a new one.

This is why; you must buy a heater with a corrosion-resistant water tank that is either glass lined or Vitreous Enamel coated.

To avoid the damage caused to other parts like the heating element, you can even buy a water softener. Here the water first goes to the water softener and the output of the softener will serve as an input to the water heater. Since the hard water is turned into soft water, you might not face any corrosion-related issues with the geyser.

8. Fuel type (gas/electric)

Most of the instant water heaters are based on two fuel types: electricity and gas. In India, using natural gas as a fuel alternative is a bit tricky. Hence, most of the models are electricity-based only. Also, these models are convenient when it comes to installation and power consumption.

We have covered only electric instant water heaters in this article.

9. Cost of the geyser

You can easily find an instant water heater in a price range of Rs. 2000 – Rs. 3500. The price majorly depends on the capacity that it offers along with the wattage used. High capacity tanks with higher wattage cost a bit more than the regular-sized geysers.

The tank material and the heating material used also have an impact on the price of the instant water heater.

10. Different warranty offers

The water heaters are more prone to damage, especially if you have a hard water supply at your home. They might require regular servicing and maintenance. Hence, it becomes even more important to buy a geyser from a reputed brand that offers a good warranty and after-sales service support.

You might face issues while giving the geyser for servicing if you buy from a local or lesser-known brand.

Some brands offer a warranty of 4-5 years on the tank and 2-3 years on the body and other parts of the geyser. Some companies even offer an overall warranty of 3 years with a 4-year warranty on the heating element and 8+2 years on the inner tank. The more the warranty period is the better it is.

Buyer’s Guide – Advanced Features of Best Instant Geyser

Apart from the essential features, some brands offer additional features to the users to make their product more trustworthy and efficient. Some of the useful additional features that you can check for are as follows:

11. Temperature control

Most of the tank-less water heaters comes with an adjustable temperature controller so that you can set the water temperature as per your requirement.

Not every model comes with this feature. It is mostly available in high-end versions.  All the basic versions come with a default water boil temperature setting.

12. LED display

LED indicators are very helpful for the users so that they know what operation is being carried out. It is a must-have feature. Most of the water heaters come with 2 LED indicator options – Green and Red color where green represent power on/off and red is for the heating element.

13. Automatic turn-off

With an auto-off feature, the heater turns off automatically after it reaches a certain temperature. This feature is very helpful in saving electricity and protecting the heater from any damage or burning. If you have a habit of forgetting to switch off the heater after using it, this can be a really useful feature for you.

14. T & P valve

These days, along with high bar pressure, some manufacturers even offer temperature and pressure relief valves or T & P valve.

The T & P valve relieves the excess temperature and pressure in the heater when either of them reaches the critical point. The thermal expansion in a closed water heater system is an inescapable fact of the functioning of both normal and abnormal water heater.

In a standard water heater, the water is heated by using either an electric element or a gas burner. When the temperature of the water reaches between 120-140 degrees Fahrenheit, both the water and the heater’s metal tank starts to expand. While a little amount of expansion is considered normal, too much expansion is totally unsafe.

When the water temperature reaches 210 degrees or when the pressure reaches 150 PSI (pounds per square inch), the T & P valve opens and starts expelling steam and hot water through the discharge tube.

Glass-lined coated inner tanks are capable of resisting high pressure and thus, are the most preferred ones.

15. ABS plastic body to avoid rusting

The ABS (Acrylonitrile butadiene styrene) plastic helps in preventing the accumulation of rust. It also offers a shock-free body to the users.

16. Fire resistant cable

These cables are helpful in limiting the spread of fire, whenever there is a short circuit.

Buyer’s Guide – What are Instant Geysers?

Lets us first check on basic facts about instant water heaters and how they work.

How does an instant water heater function?

The instant water heaters have a limited water storage capacity with high heating capacity so that the water heats up instantly.

The cold water enters inside the small storage tank via an input valve. The high capacity heating element then heats up the water quickly in the tank. This hot water is then discharged via an output tap.

Since these heaters heat up the water very quickly, they need a lot of power for a short period of time. Thus, they have such high wattage when compared to storage water heaters.

How instant are instant geysers?

The time taken by the instant water heater to heat the water depends on three factors: storage capacity of the geyser (1 liter or 3 liters), the temperature of the input water, and the wattage (3 or 4.5 kW).

On average, the temperature of water in India in the winter season varies from 4℃ to 21℃, depending on the city that you live in.

For the above temperature, it should hardly take a minute to heat the water to bath-ready temperature i.e. 40℃ and around 2 minutes if you like having a bath with very hot water i.e. around 60℃.

These instant water heaters are more suitable for areas where the water temperature does not drop too low like in most parts of South India.

Instant geyser – Advantages vs Disadvantages

Instant Geyser: AdvantagesInstant Geyser: Disadvantages
The compact body makes it easier to install the heater in any corner of the bedroom or kitchen.Since the average flow rate of a bathroom shower is around 8 liters/min, the instant water heater cannot provide so much hot water instantly.
These appliances are more energy-efficient as it heats only a required amount of water. Whereas, the storage water heater heats a lot of water which is not even used.It is not suitable for the colder area as it takes some extra time to heat up very cold water.
They are cost-effective and come at a cheaper price when compared to storage water heaters.With 3 – 4.5 kW power consumption, the heater puts extra load on the system that can lead to overload or power failure issues.
The instant water heaters are light in weight.
They are highly durable and a few models can even last for 5-10 years.
Since they have very limited (close to no storage at all), to get a continuous flow of hot water, you will have to keep the tap’s flow at a minimal level. Hence it is not suitable for families with more than 2 members.

Optimum way to use an instant water heater

Even though there is no rocket science on how to use the heater properly, there are some basic tips that can help in increasing the efficiency and the durability of the appliance. They are as follows:

As soon as you get up, you can turn on the geyser. It would take around 4-5 minutes to heat up the water. As the indicator tells you that water is hot, you can open the hot water tap at a flow rate of around 20-30%.

This way, you can start filling the bucket with a continuous stream of hot water.

In the meanwhile, you can brush your teeth and use the towel. Let the bucket fill till it is 50-60% full. You can now turn on the cold water’s tap and once the bucket is full, you will get a mix of hot and cold water.

Once you start using the water from the bucket, you can again turn hot water tap on at a 20-30% flow rate followed by cold water so that the bucket is again full for the next member.

If you use the hot water tap at a 100% flow rate, you will have to turn the tap on and off at regular intervals and you might not get hot water so quickly.
