Best Instant Water Heaters In India 3 LTR | Best Choice | Updated February 2020

Table of Contents

Instant water heaters are water heating systems with low storage capacity that are available in 1 liter or 3 liters to a maximum capacity of 10 litres. And it can quickly heat up a small amount of water.

Often known as tankless water heaters or tankless geysers, Instant water heaters. The power ratings are usually 3000 Watts and 4500 Watts for instant water heaters. For smaller families, instant water heaters are appropriate.

The instant water heater, as the name implies, is able to heat the water immediately and is made ready for immediate use. Such geysers may or may not have storage space and have a comparatively smaller storage tank for those that do.

The instant water heaters are very compact with their smaller storage tanks and do not take up much room. This is one of the main reasons people go to the water heaters instantly. You’ll also save some power and water with it since the heater won’t run idle or heat up the water that isn’t eventually used.

It is incredibly difficult to find the right Instant Water Heater since there are many options on the market. But you don’t need to be afraid, as we came up with this article, so you can easily choose the right one. Here, to help you select the right one, we have compiled a list of the best Instant Water Heaters from all well-known brands.

Why should you buy an Instant Water Heater?

There are no storage tanks for instant water heaters and they provide hot water on demand. These water heaters are also around 1/5 of the size of standard water tanks, making them easy to fit in the smallest of areas. Tankless systems are normally mounted on the wall, allowing the floor space of your home to be preserved. Another advantage is that you can mount instant water heaters and enjoy its advantages in more areas of your home.

While compared to a conventional water tank, you have to pay more for a tankless hot water system, you save a lot by running tankless for a lifetime. Firstly, the tank-free system would last twice as long as a heating system. In the first place, this makes it a smart financial decision. Even, while it is not being used, you don’t have to pay extra for heating water. The water passes through the tankless heater when you turn the tap on and delivers you a sufficient amount of liters per minute. You can save about 30 to 50 percent of your electricity by switching to an instant water heater.

Instant water heaters are designed to last longer. Modern water tanks have an 8 to 12 year lifetime. However, an instant water heater typically has a 10-15 year warranty and can continue for two decades if properly managed. You automatically double your heating system’s lifetime when you decide to turn to an instant water heater.

Traditional tank heaters for storing water can only heat a certain amount of liters at once. Although conventional heaters hold a large supply of hot water on hand, the supply is not reliable. During the day there may be plenty of water available, but as the day goes by and more people take a shower, you’ll run into trouble within no time. Water keeps running for as long as you need it, with instant water heaters. No matter how many family members take a shower, you will certainly not run out of water.

Buying Guide

Geyser Wattage

Another aspect that makes you choose the right geyser for your home is the wattage of the geyser. The wattage of instant heaters is normally high as the water heats up rapidly. They are supplied with either 3000 W (3kW) or 4500 W (4.5kW). 4.5kW instant heaters heat up the water faster than a 3kW instant heater.

Since the wattage is high, this means the electrical load would be high too. In metro cities such as Bangalore or Mumbai, for example, if all houses in the vicinity use a 4.5 kW instant heater, the electrical grid load will be too high. Eventually, this can lead to tripping or power loss.

Therefore, you should always consider your environment before purchasing an expensive and high-powered system to see if the transformer has the capacity to handle the load. 3kW geysers are an excellent choice for India houses, as they don’t impose an excessively high load on the device.

Heating Element

The heating element is just as important as any other component. Most brands use heating elements in copper with a coating to avoid corrosion of the material. Some manufacturers also use a glass-coated Incoloy heating element because it is considered the best in the industry for corrosion prevention. However, they are costly and can last for approximately 4 years, even with hard water as a source.

The glass-coated copper heating element that works well is another choice and is not that costly. Even when used with hard water, the copper-coated heating element will last for about 2 years.

Water’s Toughness

Since we all know that hard water causes scaling within the geyser’s water tank, this also causes the heating element to be harmed. The corrosion occurs quicker because of this, and you can have to either fix your geyser regularly or purchase a new one. For this reason; you must buy a heater with a water tank resistant to corrosion that is either lined with glass or covered with Vitreous Enamel.

You can also buy a water softener to prevent damage caused to other parts, such as the heating element. The water goes first to the water softener here, and the softener’s output will act as an input to the water heater. Since the hard water is turned into soft water, the geyser does not confront any corrosion-related problems.

Size of Water Heater 

For the geyser, the ideal size should be the amount of hot water that you will need for immediate use at once. There are instant geysers available in sizes from 1 to 3 liters. You will also find a few with a 6-liter size. If you are searching online, most of the available instant water heaters give a 3-liter capacity. 1-liter capacity is not really adequate to provide a constant flow of hot water and is therefore not ideal for bathing. You may use this for the washbasin too. Here is a table to help you analyze the amount of water needed that will be sufficient for your family. Let’s have a peek.

Bar Pressure

In “bars” the water pressure is determined in the water heaters Bar pressure, therefore, implies the water pressure in the geyser or heater that reaches the water tank.

That pressure varies from construction to construction. For example, if you live on the 4th floor of a four-story house, your home’s water pressure would be lower than that of those living on the ground floor. There is a high likelihood that the inner walls will become thin and weakened over a period of time as the water pressure comes into direct contact with the inner walls of the water heater tank. Often even water from the geyser tank starts leaking.

In order to obtain better results in water pressure management, it is recommended that 8 bar pressure geysers for high-rise buildings be purchased.A heater with 6 or 6.5 bar pressure can be bought for those living in an individual home and the water pressure is a little low for them.

Power Consumption

Instead of falling for the marketing gimmicks, you have to purchase an energy-efficient water heater. In general, the energy efficiency of a water heater is determined by the energy star rating (heaters with a rating of 5 stars are considered to be the best). The lower the power usage would be, the higher the BEE (Bureau of Energy Efficiency) star ranking. This, in turn, would increase the heater lifespan.

Tank Material

The material the tank was made of determines the geyser’s consistency. Its consistency is directly influencing the geyser’s durability and performance. Generally, copper, thermoplastic, or stainless steel are used to make water heater tanks.

Copper: Copper is a strong electricity conductor, and easily heats the water. The pace at which the water cools down, though, is also rapid. Thus, in the copper tanks, the heat retention capacity is limited. Copper isn’t immune to corrosion. This, it must be covered with anti-corrosive high-quality content.

Stainless Steel: Compared to both copper and thermoplastic, it is considered the strongest material as steel provides great properties in insulation and heat conductivity. It is also robust, but a little corrosive. You can, however, solve this problem by using a technology-free from corrosion.

Thermoplastic: Thermoplastic tanks are corrosion resistant. Heat retention properties, however, are a bit poor. It needs an extra inner coating on the tank walls to keep the water hot for a long time.

Fuel Type

Most instant water heaters are based on two forms of combustible: electricity and gas. In India, it is a little troublesome to use natural gas as an alternative for power. Therefore, most of the models are only electricity-based. When it comes to installation and power consumption, these versions are also easy.

We will discuss in this article the best electric instant water heater in India. 

Tank Material Coating

Vitreous enamel coating: for a stainless steel water tank, this coating is recommended as it provides great corrosion resistance. It also prevents scaling of hard water. 

Glass-lined coating: This type of coating is performed over a long period of time on either copper or thermoplastic material to retain the water temperature. With continuous use, there are chances of long-term harm to this insulation.

Warranty

Water heaters are more vulnerable to damage, particularly if your home has a hard water supply. They will need routine maintenance and maintenance. Thus, buying a geyser from a reputed brand that provides strong warranty and after-sales service support becomes even more important. If you buy from a local or lesser-known brand, you can face problems when supplying the geyser for maintenance. Some brands offer a 4-5 year warranty on the tank, and 2-3 years on the geyser’s body and other parts. Some companies also give a 3-year overall warranty with a 4-year warranty on the heating element and an 8 + 2-year warranty on the interior tank. The longer the warranty span, the better it will be.

Price

In a price range of Rs. 2000-Rs. 3500, you can easily find an instant water heater. The price depends primarily on the ability it has, along with the wattage used. High-capacity tanks cost a little more than regular-sized geysers with higher wattage. The material of the tank and the heating material used also have an influence on the instant water heater price.

Advantages and Disadvantages of an Instant Water Heater

For households that use 41 gallons or less of hot water per day, the market for water heaters can be 24 percent – 34 percent more energy efficient than traditional storage water heaters. They can be 8 percent-14 per cent more energy efficient for households that use a lot of hot water about 86 gallons a day. You can achieve even greater energy savings of 27 percent-50 percent if you install a demand water heater at each hot water outlet.

A tankless water heater ‘s initial cost is higher than that of a traditional storage water heater, but tankless water heaters normally last longer and have lower maintenance and energy costs, which may compensate for its higher purchasing price. Most tankless water heaters have more than 20 years of life expectancy. They also have easily replaceable components which prolong their lives for many more years. In comparison, water heaters for storage last 10-15 years.

The standby heat losses associated with storage water heaters will prevent tankless water heaters. Although gas-fired tankless water heaters appear to have higher flow rates than electric ones, they may waste energy if they have a constantly burning pilot light. As opposed to a storage water heater, this can also counteract the reduction of standby energy losses. The pilot light heats the water in the tank so that the energy is not lost in a gas-fired storage water heater.

In a tankless water heater, the cost of running a pilot light varies from model to model. Ask the maker how much gas is used by the pilot light for the model you’re considering. If you buy a model that uses a standing pilot light, you can always turn it off to conserve energy when it is not in use. Instead of a standing pilot light, suggest versions with an intermittent ignition system (IID) as well. On certain gas kitchen ranges and furnaces, this device resembles the spark ignition device.

Frequently Asked Question

Can instant water heaters be connected to shower?

Is an instant water heater good for the bathroom?

An instant water heater with a 4.5kW heating element can heat up to 1 litre of water in around 20 seconds. So an instant water heater will heat up the appropriate amount of water you need in the bathroom, for at least 1 shower.

What is the difference between storage and instant water heater?

At maximum temperatures, instant geysers are responsible for providing instant hot water. In the bargain, the storage geysers consume 2 KW of fuel. If you heat 15 litres of water, the same amount of power would be absorbed by both geysers. The only difference is that less time is required for instant geysers.

Is an instant water heater safe for Bath?

If it is certainly electric or gas geyser but if it is a natural geyser produced in volcanic prone areas then it may or may not be suitable depending on the salt level in the water. Just make sure that the water temperature is healthy, so that your skin does not burn.
