What is an instant water heater?

Also known as a tankless water heaters an instant water heater, as the name suggests provides instant hot water and thus avoid any water wastage. Instant water heaters do not have Storage tank there is no chance of storing hot water this makes the device small and compatible it also consumes less space then storage water heater. Before knowing which is the best version to pick, you need to know how an instant water heater works.

Working of an instant water heater:

The instant water heater works on the principle of heat exchange. Storage water heaters have a storage tank which stores water engine sheets this container and then the water from the container is flow through pipes.

  • In a tankless water heater or an instant water heater, there is a heat exchanger instead of a storage tank. This heat exchanger contains coils and other heating element through which water passes.
  • When you open the tap and the Water tankers, the heat exchangers activate.
  • The incoming flow of water is circulated through the activated heat exchanger water is expelled and the heat of the exchanger is infused into the water.
  • This instantly heats of the water inside the pipes.
  • This form of cheating requires a lot of electricity or gas or any other system of heating.

Factors to Consider while choosing Best Instant Water Heater

1. Types of Instant Water Heaters:

Thought the principle of operation of an instant water heater is the same, it has two different types of modes. These type of heaters are of two types are as follows.

  • Point of use heaters
  • Whole house heaters

Point of use heaters are small in nature and provide hot water in one or two outlets of your house. You can either heat the water in your kitchen or your bathroom or just both. They are very small and can easily fit on top of the shower or any corner of the bathroom or even under the sink. They are preferred by small families and bachelors because they are small, easy to use and they do not have lag time, that is the time taken for the hot water to reach your outlet. The types of water heaters are usually electric in nature. And they also consume a lot of electricity.

The second type of instant water heater is the whole house water heater. As the name suggests it does not need only one outlet. It has more than one outlet but it consumes energy it has a lot of lag time. It is usually chosen by largest families and bigger houses. Whole house water heaters are not only electric but they are also gas propelled.

2. Water Tank Capacity

Knowing the water tank capacity helps to decide the right one matching with the family size and to your home/bathroom size too. Most of the instant water heaters in the list come with a tank capacity of 1-3 liters of water which makes it good enough for small families to perform activities like hand wash, face wash, cleaning utensils, bucket and shower bathing.

But a 1,2, 3 or 6 litres capacity does not need to be the only thing you have to consider while buying an instant water heater. Different homes and different family sizes need different sizes of the tanks.

Given below is a table that will let you understand how many liters of water tank capacity supports which family size. Have a look!

Water Tank Capacity Vs Family Size

Water Tank Capacity Family Size Application
1 Litres Singles/Bachelors (1) Face wash
2 Litres 1 – 3 Members Washing utensils
3 Litres 2 – 4 Members Bucket bathing
5 Litres 4 – 5 Members Shower bathing
10 Litres 6 + Members Hand wash, dishes, bathing

3. Hardness of Water

Hard Water is a bad news to your water heater’s health. Hard water is nothing but water with high mineral content such as magnesium and calcium which is not exactly a health hazard but can damage your clothes, containers and equipment it passes through. If the water you use contains more salts and minerals then it’s a clear indication of hard water which damages the lifespan of the geyser.

Try to be sure that the water you use for your daily usage is soft water. The best solution is to use corrosion-resistant water tank to avoid damage for heating element. It is also recommended to use a water softener inside the steel tank to convert the hard water to soft water.

4. Power Consumption

Let me establish this first that Instant Water Heaters are notoriously known for their energy consumption.

A quality and best water heater should consume less power but provides hot water within a few seconds while turning it on than any basic instant geyser models. A lot of companies promise miracles on touch but often than not, they are all false.

So, it’s important for an individual to choose the energy-efficient water heaters for home without falling into the marketing gimmicks.

In general, the energy efficiency of a water heater is determined by its energy star rating (5-star is mostly preferred). Higher the BEE (Bureau of Energy Efficiency) star rating less power consumption and thereby increases the lifespan.

Typical storage geysers have a 2 KW power rating but instant geysers tend to have near double of that rating from 3-4.5kw. But your choice should also be considered while looking at your neighbourhood too.

For instance, you are living in a metropolis such as Mumbai or Bangalore, if all the houses in your vicinity are using 5 Kw instant water heaters, it will inadvertently cause load to your grid and cause it to trip or worse, fail.

Hence before going for a flamboyantly costly or high powered machine, please consider your surroundings and the capacity of your areas transformers and your own house wiring.

5. Stylish and Attractive Design

It is also important to look after the build design and quality. If the product you purchase has average build quality, then the electric water heater may damage quickly resulting in a huge loss – power issues, water leakage, improper functioning etc. It’s totally a waste of your time and money.

Also, nowadays people are showering their interest to the high-class geysers so as to fit perfectly into the home interiors and look stylish when you place in kitchen or bathrooms.

6. Check Online Prices and Warranty Information

At this point, almost everyone knows that offline prices have a large gap with online prices. So it is important to compare the product you choose to that of the same product available in different portals. While Amazon is the defacto trust house for quality, you need to check with the warranty information of the product.

Popular brands offer high quality products along with the standards customer support services. When you find a damaged piece, visit the authorized service center to get repair for free of cost. Whereas, the cheap quality models has less lifespan and do not provide warranty information too. So, it’s better to go with the high-end geysers that offer decent performance throughout the usage.

7. Smart Features in Instant Water Heater

a) Temperature Control

Tankless water heater comes with an adjustable temperature controller to set the water temperature at a steady rate. If you run the water quickly, then the water won’t be too hot. Hence, it’s good to maintain the ideal temperature conditions to flow the water and warm water instantaneously.

Understand that not every model comes with a temperature control option. This is usually a high end version option and basic versions have a default water boil temperature setting.

b) LED Indicators

LED indicator is a must-have feature in water heater that helps the user to know what operation is carried out. Ideally speaking, the water geysers come with 2 LED indicator options – green and red light. Green light indicates the power on/off and red for heating element.

c) Auto off Feature

This is an important feature of any water heater that automatically turns of the appliance even if you forget to switch off the heater after use. This feature helps to save electricity and protects the heater from burning or damage.

d) Pressure Valve

You should never forget about the pressure valve. Because, a pressure valve in a geyser plays a prominent role that allows hot water to fill in the bucket at the outlet pipe. It is made of sturdy materials, hence there are less damaging the valve. The bigger the pressure valve, the higher is the water pressure.

Pressure valves are usually narrow, thus give very narrow stream of hot water. Takes a few full minutes to fill up the bucket of water. Hence, look for a model with a slightly less narrow pressure valve. You don’t want to wait for a long time to get the already heated water right?

Advantages of a instant water heater:

  • Faster and instantaneous water heating for bathing and regular usage purposes
  • Smaller body makes for easier fitting to almost any corner of the bathroom, kitchen or any room required.
  • Most instant water heaters are “tankless”. This means that there is no tank that first needs to be filled and then needs to be heated. Water gets heated on the go.
  • As they heat only when required, this adds to the safety of maintaining them.

Safety Tips and Precautions While Using Water Heater

  • Always keep the surroundings of water heater clean and hygiene.
  • Keep the device away from combustion and flammable materials.
  • Do not allow your children to touch or play with the water heaters.
  • Save your electricity bills by keeping the temperature to low/medium.
  • Make sure the LEDs, switches, pressure valve are in good working condition.
  • Never forget to switch off the geyser once you collect bucket full of hot water.
  • Clean the device once a week to prevent from blockage, rusting and other issues.
  • If you do not know how to install the water heater, make a call to the professionals.
  • Choose the right sized geyser for your home purpose and keep it at certain height.

  • When you buy water geyser online, check the product quality, price and warranty information.

Frequently Asked Questions ?

1. What is the difference between a storage geyser and an instant geyser?
