Best Geyser for Hard Water in India 2023

In India hard water can be big problem due to erratic water supply in most areas even in 2023. So better select a water geyser which can overcome the effect of the hard water.

We recommend to use Geyser which have all these three properties for corrosion resistance:

1. Glass lined water tank: Coating of glass can help reduce the corrosion level of water tank of geyser to very large extent. Also material used should be corrosion resistant in it’s properties.
2. Glass coated incoloy heating element: Incoloy is an alloy which doesn’t corrode easily and is excellent on heating capability with high melting point while similar to tank now glass coating on heating element too save it from corrosion giving it double protection.
3. Anode Rod: Anode Rod attracts the sediment and corrosive elements (like minerals in the water) to corrode itself rather than the water geyser tank and its heating element.

Till date we found only two brands which give all these features and these are AO Smith and Havells. We have done even the comparison of these two : AO Smith vs Havells Geysers

Hard water can have several effects on a metal water tank, especially if the tank is part of a water heater system. The primary concern is the presence of minerals, such as calcium and magnesium, which can cause the following issues:

1. Scale Buildup: As hard water is heated and evaporates, the dissolved minerals can form scale deposits on the metal tank’s interior surfaces. Over time, this scale can accumulate and reduce the tank’s efficiency and capacity. It can also insulate the water from the heating element, making the heater work harder and potentially leading to premature failure.
2. Corrosion: Hard water can contribute to the corrosion of metal tanks, especially if the minerals cause pitting or weak points in the tank’s surface. Corrosion weakens the tank and can eventually lead to leaks and failure.
3. Reduced Lifespan: The combination of scale buildup and corrosion can significantly shorten the lifespan of a metal water tank, including those in water heaters. The accumulated mineral deposits and corrosion can create conditions that promote leaks and structural failures.
4. Poor Heating Performance: Scale buildup on the heating element in a water heater can act as an insulating barrier, making it more difficult for the heating element to efficiently transfer heat to the water. This can result in longer heating times and higher energy consumption.
5. Maintenance Issues: A metal tank affected by hard water may require more frequent maintenance to flush out scale deposits and address corrosion problems. Neglecting maintenance can exacerbate the issues and lead to costly repairs or replacements.

To mitigate the effects of hard water on metal water tanks, it’s essential to take preventive measures such as:

1. Regular Maintenance: Flush the tank periodically to remove scale deposits and sediment buildup. Flushing can help maintain the tank’s efficiency and extend its lifespan.
2. Install a Water Softener: Consider using a water softener to reduce the hardness of the water before it enters the tank. A water softener can help prevent scale buildup and reduce the negative impact of hard water on the metal tank.
3. Use Sacrificial Anode Rods: In water heaters, sacrificial anode rods are used to prevent tank corrosion. These rods attract corrosion and scale-forming minerals, protecting the metal tank from damage. Ensure the anode rod is checked and replaced regularly.
4. Choose the Right Tank Material: If possible, opt for water heaters with tanks made from materials less susceptible to corrosion, such as stainless steel or glass-lined tanks.

By implementing these measures and maintaining your water heater regularly, you can minimize the effects of hard water on the metal tank and extend its overall lifespan.

When dealing with hard water, it’s essential to choose a water heater that can withstand the effects of mineral deposits and scale buildup. Hard water contains high levels of minerals like calcium and magnesium, which can accumulate inside water heaters over time and reduce their efficiency or even damage the heating elements. Here are some considerations for selecting a water heater for hard water:

1. Tank Material: Look for water heaters with tanks made from materials that are less prone to corrosion and scale buildup, such as stainless steel or glass-lined tanks. These materials can better withstand the effects of hard water and increase the lifespan of the water heater.
2. Anode Rod: The anode rod is a sacrificial component in the water heater that helps prevent tank corrosion. For hard water, consider using an aluminum or magnesium anode rod, as these rods tend to work better in areas with high mineral content.
3. Self-Cleaning Feature: Some water heaters come with a self-cleaning feature that helps reduce sediment buildup inside the tank. This feature can be beneficial in areas with hard water.
4. Regular Maintenance: Regardless of the type of water heater you choose, regular maintenance is essential. Flushing the tank periodically and descaling the heating elements can help prolong the life and efficiency of the water heater.
5. Water Softener: If you have extremely hard water, installing a water softener for the entire household can significantly reduce the mineral content in the water. This will not only benefit the water heater but also other appliances and plumbing fixtures in your home.
6. Tankless Water Heaters: Tankless water heaters can be a good option for hard water areas since they don’t have a tank where sediment can accumulate. However, they are still susceptible to mineral buildup on the heating elements, so regular maintenance is necessary.
7. Brand Reputation: Choose a reputable brand known for producing water heaters that are designed to handle hard water conditions. Reading reviews and seeking recommendations from professionals can be helpful in this regard.

Ultimately, the best water heater for hard water will depend on your specific needs, budget, and the severity of the hard water in your area. Be sure to consult with a plumbing professional to determine the most suitable option for your home.
