Best Geyser For Hard Water : Buying Guide

When it comes to choosing the best geyser for hard water, it can be tricky sometimes. However, there are a few things to keep in mind when making your decision. These include the cost of the unit, the energy efficiency, the installation process, the size, the fuel source, and the warranty.

Tankless or with the tank

You’ll first need to decide whether you want a tankless or a tank geyser. Tankless geysers don’t have a storage tank and heat water on demand. It makes them more energy-efficient since they only heat water when needed. They’re also smaller and take up less space.

With tank geysers, hot water is stored in a tank and is available on demand. These models are typically less expensive than tankless models, but they’re also less efficient since they keep heated water in a storage tank.


The next thing to consider is the cost of the unit. Again, selecting a model within your budget is essential, so you don’t overspend. However, you also don’t want to choose the cheapest model available since it may not be durable or energy-efficient.

Energy Efficiency

When selecting a geyser, it’s important to choose an energy-efficient model. This will help you save money on your utility bills and do your part to protect the environment.


Next is the installation process. Some models are easy to install, while others require professional help. It’s important to select a model that you can install yourself to save money on installation costs.


The first is the size of the unit. Geysers come in various sizes, and it is essential to select one large enough to heat all the water you will be using. If you have a large family or plan on using the geyser for commercial purposes, you will need a unit capable of heating a large volume of water.

Fuel Source

The second thing to consider is the fuel source. Either electricity or gas can power geysers. Each has its advantages and disadvantages. Electric geysers are more expensive to operate, but they are much more efficient. Gas-powered units are less costly to use, but they can be less reliable.


You should consider the warranty that comes with the geyser. Most units come with a one-year warranty, but some have more extended warranties. If you plan to use the geyser for an extended period, selecting a unit with a longer warranty is essential. It will ensure that you are covered in case anything goes wrong.

Safety Features

When selecting a geyser, choosing a model with safety features is important. It will help you avoid accidents and injuries. Look for a model that has an automatic shut-off feature. It will prevent the unit from overheating and causing a fire.

Family Size

Selecting the right size is important because if the geyser is too small, it will not be able to heat all the water you need, and if it is too big, it will be a waste of money.

If you have a large family or plan on using the geyser for commercial purposes, you will need a unit capable of heating a large volume of water. On the other note, if you have a small family, you might not need such a big-sized geyser which will help you save money.

Heating Element

The heating element is an important factor to consider when selecting a geyser. The geyser’s heating element will help heat water quickly and efficiently. The element’s material also plays an essential role in determining how long the geyser will last. Titanium is the best material for the heating element as it is durable and resistant to corrosion.

Considering these factors, you can be sure to find the best geyser for your home. With some research, you can find a quality product that will provide you with years of service.

Frequently Asked Questions (FAQs)

What are the effects of Hard Water on Geysers?

The main effect of hard water on geysers is the build-up of scale inside the heater. This can reduce the efficiency of the geyser & in some cases, cause it to fail completely.

Does hard water damage the geyser?

Hard water is bad news for your geyser. All types of geysers are impacted by hard water, making it difficult for them to function correctly.

How can a hard water problem be resolved?

A Water Softener is the most common method to address hard water. This water filtration system filters out hard water minerals.

Is hard water safe to drink?

Water with high mineral content, such as hard water, isn’t dangerous, and while it does have extra minerals that might make the flavor unpleasant, it is usually safe to consume.

How does hard water affect hair?

When calcium and magnesium accumulate in the water, it is called hard water. This causes a film to form on hair, preventing moisture from being absorbed. The result is dry, brittle hair that breaks easily. If these issues are not resolved, they could even lead to hair loss.

How long will a water heater last with hard water?

Using hard water will shorten a water heater’s lifespan by a few years.


Although selecting the best water heater for hard water is similar to choosing any other home heating system, one key exception exists: you must find a unit with unique features that make it more resistant.
