Protect Geyser from Hard Water

How to Protect Your Geyser from Hard Water?

Just like every other electrical appliance, your geyser also has a definite life cycle. However, the life of your water heater largely depends on the quality of water being used. In India, water is utilized from diverse sources like rivers, borewells, and tankers. Some of these sources may provide you with hard water, which can be highly detrimental to your geyser.

Hard water can harm your geyser in many different ways. It can cause sludge and scaling which can lead to corrosion,. This could reduce the heating efficiency of your geyser and increase your electricity bills. As a result, your geyser may break down much earlier than its anticipated lifespan. Hence, it is crucial to protect your electric geyser from hard water and get it serviced regularly.

In this blog, we will provide you with various methods to safeguard your geyser from hard water and keep it up and running for years.

What is hard water?

When there is a high level of calcium, magnesium, and other minerals dissolved in water, it is considered as hard water. It means that hard water has a high mineral content that can damage your geyser internally as well as externally.

Hard water is measured in parts per million (ppm). If the water is between 60-120 ppm, it is moderately hard, while water beyond 120 ppm is con as hard water.

How does hard water affect your water heater?

Hard water can be highly detrimental to your water heater. It can damage your geyser in many ways. Here are some of them for your understanding:

1. Hard water can cause scaling

Hard water can cause scaling in your water heater. Due to this, the thermostat may cease to function. Besides that, scaling could also affect the heating efficiency of your geyser. That means your water heater could take much longer to heat a lesser amount of hot water. As a result, your electricity bills could increase drastically. In some cases, scaling could also lead to a complete failure of the heating element.


2. Hard water can cause corrosion

Hard water can damage the tangible parts of your geyser.

Salty water or excessive chlorine content in water causes deterioration of the surface coating which can lead to tank corrosion and tank leakage. This can severely affect the lifespan of your geyser.


3. Hard water can increase your electricity bills

Hard water takes more time to get heated. Thus, your electric instant geyser consumes more power to heat the water. This can drastically increase your electricity bills.

4. Hard water can lead to sedimentation in your water heater

When hard water gets heated, it leaves behind some mineral residues in the tank. These minerals get deposited on the tank surface in the form of sediments. As a result, your water heater may begin to make a rumbling sound when you switch it on.

How to protect your water heater from hard water?

While hard water can be harsh on your geyser, you can take preventive measures to safeguard your water heater. Here are some of the things you could do to shield your geyser from hard water:

1. Service your water heater regularly

One of the best ways to prevent corrosion is to get your water heater serviced regularly. Servicing your water heater every six months reduces the chances of corrosion on the rod. As a result, it leads to efficient heating, greater savings, and improved durability. In fact, regular servicing not only improves the performance of your geyser but also helps you sustain its lifespan.

2. Replace the sacrificial anode on a regular basis

To prevent corrosion caused by hard water, water heaters are equipped with a sacrificial anode. However, this sacrificial anode gets consumed over time. Thus, it needs to be changed on a regular basis otherwise the tank and the heating element become vulnerable to rust formation. However, the ideal frequency of changing the anode will depend on the water conditions.

3. Use water softeners

Hard water can be converted into soft water using a softener. A water softener converts magnesium and calcium into softer forms. Softeners also help you avoid salt formation on the geyser walls. Additionally, the extra lather generated by soft water is good for your skin and hair. Thus, it enhances your overall experience.

At Racold, we recommend using the Anti Scaling System to prevent salt formation. It’s an effective product that can easily be installed. Not only does it saves space but also ensures zero water wastage.

4. Go for geysers with corrosion-resistant features

you live in a hard water-prone area, we recommend choosing geysers that have corrosion-resistant features. Look out for features that protect the tank and the heating element from rust.

Our range of electric geysers includes a sacrificial anode called Smart Guard. It employs an electrolytic process to shield the heating element from corrosion and secure the efficiency of the water heater.

Additionally, Racold’s electric water heaters are equipped with Titanium Plus Technology that safeguards the tank as well as the heating element from corrosion and ensures a longer life.
