Types of Geysers

If you’ve decided to upgrade and buy a new geyser, you’ll want to make a well-informed purchase so that you know the one you pick will meet all of your needs.

Finding the best geysers can be challenging, so it helps to know the pros and cons of each type. There’s a lot more to geysers than just getting your water hot. Here is a list of the different kinds that are out there.

  1. Electric: –

Electricity powers the most common kind of geyser. Electric geysers tend to heat water to a higher temperature than other geysers, which is one of the main reasons they are so popular.

An electric geyser is probably one of the least expensive options, and it’s usually easy to put one in. But you should know that running electric geyser costs can be pretty high. This is one reason you should choose a model with the right size and level of performance for your needs to keep your running costs as low as possible.

  1. Gas: –

Gas geysers are next on the list. This type of geyser needs to be hooked up to LPG, and compared to electric models; it doesn’t cost as much to run. But they pose a more significant safety risk and must be adequately ventilated. This is why people who want to upgrade their geyser are looking for other options.

  1. Instant: –

Another option to think about is a geyser that doesn’t store water but heats what you need right away. An instant geyser is a good choice for a small household that doesn’t need a lot of hot water. However, if you think you’ll need more than three litres of hot water, this geyser might not suit you.

  1. Storage Geyser: –

As the name suggests, a storage geyser has a metal tank that can hold enough hot water to give a family home the hot water it needs daily. This type of geyser is strong and lasts a long time, but you should know that it might cost more to run than other options.

  1. Solar: –

We all need to think about eco-friendly choices when we can, which is why a solar geyser is something to consider. A solar geyser can heat your water in just a few minutes, and you won’t have to worry about how much it will cost to use electricity. Installation is usually more complex and costs more, and stormy weather could affect how well it works.

  1. Tank Geyser: –

You could have the option of selecting anything like a tank geyser from the available options. This is the same as a storage geyser, which may be powered by the sun, gas, or electricity.

  1. Tankless Geyser: –

You might also see the word “tankless” used to describe a model. This section talks about models that heat water immediately and don’t have any way to store it. Now that you know a little bit more about the different kinds of geysers and how they work, you should be able to decide which type and model will work best for your needs.

A Buying Guide for the Best Geyser to Use with Hard Water

Here we have listed a few significant elements that you must think about throughout your purchase trip if you are clueless or confused.

  • Geyser Heating Element Coating

The component of a geyser responsible for heating the water is the most crucial portion. Because the heating element is responsible for increasing the temperature of the water, the scale will begin to develop on the heating element as soon as it comes into contact with hard water, covering the whole heating element. The geyser will not only be less effective as a result, but it will also last for a shorter time.

Therefore, to prevent this issue, you want to ensure that the heater is completely covered with glass or another material that may shield it from the damaging effects of hard water and extend its lifespan.

  • Geyser Size

It is not always easy to determine which size of geyser would serve your needs best when shopping for one. Therefore, it is essential to give some thought to the size of your family, whether it be little, medium, or large. Consider the amount of water that you will need as well.

Therefore, if you have a few members in your household, you won’t need more than 10L. If you have a family on the larger side, you should look for one with more than 15 litres capacity, while if your family is on the smaller side, 15 litres or less will suffice. If the size of your geyser is enough, it should be able to satisfy all of your requirements while reducing the amount of money you spend on power.

  • Warranty and Price

When making a purchase, careful consideration of the warranty terms is of the utmost importance. Because of this, if you want a geyser that can withstand the harsh conditions of hard water for an extended period. 

Then it would help if you looked into the guarantee that covers the tank and the heating element. In case you need to replace it or repair it in any way. There is a wide variety of pricing points for geysers, and several factors determine the final cost of a geyser. Therefore, you have to be aware of the amount of money you own.

  • Geyser Tank Material and Size

In particular, if we live in a region that has hard water, we need to inspect the material and coating that are found on the interior of the tank of the geyser before making a purchase.

Hard water may damage everyday objects considerably more rapidly, and your geyser will also function less efficiently. If you happen to live in a region with hard water, your best bet is to look for geysers with tanks that are coated to prevent rust from forming. This helps prevent the tank from rusting and building up scale inside.

  • High-Quality Anode Rod That Lasts a Long Time

Anod is effective in a wide variety of waters, prevents tank and heating element corrosion, and lasts twice as long as other forms of anodes. Therefore, you must ensure that the geyser you choose has a rod of sufficient grade.

  • BEE Energy Star Rating

The number of stars that the BEE awards to a product is determined by the total quantity of energy used over its lifetime. When you go shopping, this is one of the most significant aspects that you will need to pay some attention to, so make sure that you keep it in mind, as it is one of the components that you will need to spend some time.

As a consequence, you shouldn’t settle for anything less than a water heater that has been given a rating of five stars for the energy efficiency it delivers. The cost of a geyser may vary widely and is determined by several variables. To that end, you must be transparent about your financial situation.


Ques 1: Does water that is too hard damage the water heater?

Ans 1: – The use of hard water not only reduces this device’s efficiency but also can potentially destroy it. Therefore, if you are interested in purchasing a heater or geyser, you should choose one that can function well with hard water.

Ques 2: What are the best geysers for hard water?

Ans 2: – If you live in an area with hard water, you should acquire a geyser with an anti-corrosion water tank and an anti-corrosion heating element to ensure that it will last for a very long time. Hard water may cause more rapid wear and tear on your equipment.

Ques 3: What to do if your geyser won’t heat up?

Ans 3: Utilizing a water softener is the most effective method for preventing the breakage of other geyser components, such as the section responsible for heating the water. The water first passes through a water softener, modifies water, and then travels into a geyser, where it is heated. Because of the gentle nature of the water that emerges from the geyser to you, it won’t damage the geyser’s components.

Ques 4: Which geyser holds the most water and is the best?

Ans 4: – If you are looking for a geyser with a significant amount of room for water, another option is this water heater made by Bajaj. The inner tank of the four-star geyser is built of glass and covered with a technique called Titanium Armour, which prevents rust and corrosion from occurring within the tank.

Ques 5: How does a geyser work?

Ans 5: – Glass is used in the construction of the geyser’s heating element, which allows it to retain its integrity while being subjected to high levels of mineral content in the water. In addition, it prevents the minerals from clumping together, which guarantees that the system will operate correctly and that there will be enough warm water supply. The water temperature may be adjusted using a knob on the geyser.

Ques 6: How to decide which geyser is best for your home?

Ans 6: – If you want to buy home appliances online and require a lot of hot water, you may discover geysers that will satisfy your demands on the online marketplace. Geysers are constantly releasing large amounts of hot water into the atmosphere. Geysers are preferable to other options when young children are in the house.
