Winters are around the corner and are you looking for a geyser that suits your home the best? You have arrived at the correct spot!
We have listed your best geyser for hard water along with some additional information. Do not forget to look out in the FAQ section if you have any doubts.
Does hard water damage the water heater?
Yes, hard water contains excess minerals such as calcium and magnesium which do no harm when you consume it. On the other hand, when hard water is supplied to the geyser it builds up a layer at the bottom of the heater which reduces the heating rate of the water inside the tank.
It could also result in severe damage to the heater. Hardwater leads to reduced efficiency, high operation cost and also decreases the actual capacity of the tank.
However, you can reduce the damage the hard water causes to your geyser following these three methods –
1.Flushing the geyser once in a while
2.Maintaining the right temperature
3.Treating the tank with chemicals
How to choose the best geyser?
- Firstly, take into account the number of members of your family. Accordingly, choose a geyser that has a tank capacity equivalent to the count of people.
- Next, your region or the area where you install the heater plays a major role. If your place is hot, purchasing a solar water geyser might be beneficial.
- If you live in a colder place, you and your family would require a heater that has a bigger storage unit as you might tend to bathe more than once per day.
- Regardless of the weather conditions, you should have a fair knowledge of the water that is supplied to your homes. Hard water might damage your heater, so prefer to buy a geyser that comes with corrosion resistant technology.
- The electricity that is being consumed by the water heater is another factor to be considered. While solar geysers do not shoot up your bills, the ones based on electricity and gas might cost you a bit more. So, plan accordingly.
- Lastly, do not forget to check the BEE star rating that is given to the product.

FAQs
1. Does hard water cause damage to my water heater?
Hard water not only stains and builds upon the appliances you use. It causes even more harm to pumps, pipes, nozzles, and motors.
The limescale that builds up may cause damage to moving parts and might even lead to dysfunction of the machine.
2. How to safeguard my water heater from hard water?
The hard water leads to the formation of calcium deposits and below are few suggestions to fight against deposits:
a. Flush the geyser – Once in a year, switch the water heater OFF and let it cool and then drain. This will flush out the calcium particles if present.
b. Treatment with chemicals – Using lye or vinegar you can combat the buildups of calcium. After flushing once, allow the chemicals to sit in the storage tank for some time. Flush once again before you turn the geyser ON.
c. Maintaining the right temperature – The higher the temperature set, the hotter the water. This will lead to increased deposition of calcium. It is advised to not go beyond the recommended temperature by the manufacturer.
3. How long do water heaters function well with hard water?
An average geyser should last anywhere between 8 – 12 years, it might even last 15+ years when maintained well. Also, when hard water is supplied frequently it reduces the life span by two years.
As the anode that attracts the corrosive element wears away after a maximum of 10 years. However, the lifespan depends on many factors such as quality of the product, maintenance, proper usage of the heater, power source, installation location, etc.
4. Can filter reduce damage by hard water?
Yes, filters are capable of removing the minerals that cause scale formation. A filter treats the water before it enters the water geyser to prevent deposits from piling up on the base of the heater and obstructs its performance.
Using a filter helps in reducing maintenance costs and the continuous flow of hot water.
5. Why do I hear noises from my water heater?
You might hear rumbling sounds from the heater and might wonder the reason that caused it. When heaters are used over time, a layer of sediments gets deposited at the bottom of the tank.
When the machine starts to function, the water inside gets heated along with these sediments. So, when the particles boil, it produces sound.
CONCLUSION
If your family is small and you feel that a 10-litre storage tank would work fine, then go for Havells Montana water heater. Whereas if you are on a budget, the Crompton Amica water heater would suit you the best.
If you are a technology freak, try opting for the AO Smith water heater. Pick up the best one based on your choice and make a wise decision with the help of the review above.
