 Buying Guide for the Best Geyser for Hard water

One of the most commonly seen problems with hard water is the formation of scaling. Hard water has a high concentration of iron which causes scaling in the inner side of a water tank. Scaling is a  kind of rust that corrodes the wall of a storage tank if it is not maintained properly. Therefore, it is better to have a geyser that can effectively handle hard water scaling issues.

If you are confused about how to select the best geyser for hard water in India, then we have curated the list of the best geysers for hard water from which you can easily pick the most suitable one for you.

But, hold on a second.

How can you find out whether your water source is hard water or soft water? Well, to know the answer you need to go through our detailed guide about how to buy the best geyser for hard water. 

What is Hard Water?

Water in which magnesium, calcium, and ferrous (iron) are dissolved in large quantities is called hard water. Magnesium and calcium are present in hard water in the form of salts like magnesium sulfate, magnesium bicarbonate, calcium carbonate, calcium sulfate, etc. The presence of iron also makes the water hard. 

What is soft water?

Water that is free from the salts of calcium and magnesium is known as soft water.

What are the differences between Hard and Soft water?

Hard water

  • High concentration of magnesium and calcium salts
  • Hard to get foam and lather from soap
  • Magnesium and calcium create hard scaling inside the water tank, pipe kettle etc
  • Brown or yellow spots are seen on cooking dishes and utensils and washed clothes 
  • Requires a lot of soap and detergent
  • Damages water tanks, clog pipes
  • Comes from groundwater where there is the presence of magnesium and calcium in soil.
  • Creates dry skin and dry hair issues
  • Good for health as drinking water if magnesium and calcium are present within specified limits.

Soft water

  • Low or free from calcium and magnesium
  • Easily produces lather and foam when soap is mixed with water
  • No such formation of scaling or hard disposition
  • Free from spots and stains
  • No wastage of soap and detergent
  • No such damage happens
  • Present in rainwater etc
  • Skin and hair remain soft and silky
  • No so good as drinking water

How to know if the water is hard or soft?

The following tests will tell us whether it is soft water or hard water.

Soap test

Mix soap with water. If it does not produce any foam/ lather or very little foam then it is hard water. 

Calcium and magnesium dissolved in hard water react with soap fats and form a curd-like layer without producing foam or lather.

Check cooking utensils:

Hard water generally leaves brown or yellow spots. If you notice any such stain mark on them then the water is hard water.

Scaling or solid disposition:

Check the insides of your water tank, water spout, coffee maker, and tea kettle. If any hard disposition or scaling is noticed then the water is hard water. 

5 Tips to protect Geyser from the damage of hard water

Corrosion Resistant  Water Tank

Certain tanks are specially designed to prevent decay and corrosion. Corrosion happens when the hard deposition of magnesium and calcium forms scales and rust. So, go for the geyser that offers a water tank protected with inline glass enamel or titanium coating.

Choose a geyser with the Magnesium anode rod

Magnesium anode rod actually collects dissolved minerals like magnesium, calcium, etc so that they can not form a hard layer inside the water tank.

Set heating point at low temperature

 When water is heated, hot and boiled water discards dissolved particles of iron, calcium, and magnesium and they get settled at bottom of the water tank and create scaling. So, the lower the temperature, the less will be the hard disposition.

Buy  water softer

This is the best way to solve hard water issues. Install water softer at the source of water. This will make hard water soft by removing magnesium and calcium.

This will not only protect your water geyser but also other tools and appliances like washing machines, electric kettles, stainless steel utensils, etc.

Use water filter

Install a water filter with the supply water pipe leading to your geyser. This will remove iron and other particles and will save the geyser from corrosion and rust.

These filters are not costly and available in the market.

Secret Tips to remember before buying  the best electric geyser for hard water

Price of geyser

Before buying anything including a geyser the first that comes to our mind is the price of that product.  In many cases, we check the price first then we look for the features.

So, decide how much you spend on a geyser and what features you are looking for in a water geyser. The list that we have provided here will fit the budget of most of the users. However, choice and capacity differ from person to person. 

Geyser  water storage capacity

Choose a geyser size based on your family size.

For 2 persons with a child, a 10-liter geyser is sufficient.

For a 3 to 4 member family, 15 Litre is ideal.

For more than 4 member family go for 25-litre geyser.

Having said that, the capacity may still vary according to the water usage. If you take a long shower in a cold atmosphere, then you might need a bigger storage geyser. But, we will urge you to save water.

Protection from hard water corrosion

Pick that geyser that has extra protection against corrosion, rust, and scale from hard water. Glass coated enamel tank and the titanium-coated tank will provide you with the best protection. It will not only extend the life of a geyser but also save money.

Electricity consumption

Go for the geyser that saves energy. Bureau of Energy Efficiency (BEE) specified geysers with star ratings are the best.

4 stars and 5 stars rated geysers save maximum electricity. So, try to buy the geyser with higher star ratings because a higher number of stars means lesser energy consumption.

Besides, some advanced features of a geyser-like fast heating, and titanium coating, will save energy.

Again, other factors like quality of water, water pressure, and weather are some of the factors that determine energy consumption. So, consider all these aspects before buying a geyser.


Again, a warranty is an important factor in purchasing a geyser. Some brands are offering 7 to 8 years of warranty.

The more the better. Within the warranty period, it is the responsibility of a company to take care of the geyser if anything goes wrong. So, with an extended warranty period, you remain trouble-free.

Customer Feedback

It is a smart thing to have a look at the opinion of the customers who are actually using the product. So, they will provide you with unbiased feedback, pros, and cons about a particular geyser.

This valuable information will help you a lot to make decisions about your purchase. You can easily check customer reviews on platforms like Amazon by visiting the site.

Installation and After-sales service

These are the two vital points to consider.  Most companies offer free installation services. However, a few of the charges for installation. Therefore, check this aspect before buying.

Also, look for the after-sales service of the company that you are choosing. Most of the brands provide quick and free installation services in Metro cities.

But, when it comes to smaller cities and towns the service sometimes becomes very poor and pathetic.

So, before selecting geysers from a brand, check very well as to whether they offer better customer service in your area or not.
