Temperature Control

One of the best parts about AO Smith geysers is that they generally come with a thermostat that allows you to manually adjust the heating settings for personalized hot water. This is great if you live in a region with varying climates. While temperature control is a very common feature, we do not get to see that in mainstream storage geysers in India. Those that do have that, are generally more expensive than the basic kind.

While some AO Smith geysers allow you to set the heating potential to exact temperatures, others come with three options to choose from, low, medium, and high. This is a great feature most AO Smith geysers come with, and really allows you much more control over the appliance.

Ease of Use

Geysers are rather basic appliances. They work on a simple methodology, so making innovations when usage is concerned can be a little tricky. AO Smith however, beats that too. First of all, most models come with a thermostat that allow you total control over your geyser. Besides that, some models even come remote enabled. So, you can easily control their functioning using a remote control. That’s great isn’t it.

AO Smith geysers are actually pretty good when it comes to ease of use and potential. Unfortunately not a lot of people have opened up to these extra features yet, and hopefully they might soon.

Ease of Installation

When it comes to installation, while they are just as easy to install as any other geyser, AO Smith geysers are actually a little more due to their smaller sizes. The compact geyser allows you to totally handle the installation yourself. If you have experience with plumbing and electricity, you can actually totally handle the installation by yourself.

There are no extra parts that you have to worry about, and you can even get a professional to do it for you. AO Smith has a great customer service system that provides professionals for installing the geyser.


When it comes to durability and quality of components AO Smith does not lag behind any other brand on the market. One of the best parts about AO Smith geysers is that they last an incredibly long time with minimal maintenance. If you are someone who just buys a geyser and forgets to maintain it until it breaks down, you might find AO Smith best for your requirements.

While they can last easily around 6-8 years, you can effectively double this time scale if you simply make sure to take care of your appliance. Maintenance of an AO Smith geyser is also incredibly easy and straightforward. Calling in professional help from the company itself can really help boost the life-expectancy of your geyser.

You will be glad to know that some AO Smith geysers come with 7+ years of warranty since their appliance are so incredibly durable.

Features and Key Technologies

Here is where AO Smith really takes the cake. They have some of the most comprehensive geysers on the market. Since they are unlike most other consumer brands out there, who tend to manufacture tons of different other appliances, AO Smith generally only works with geysers and boilers. This allows them to innovate their manufacturing line and come out with tons of great features.

Here is a list of the best features you can find in AO Smith water heaters.

  1. Blue Diamond Glass: AO Smith geyser’s inner layer comes with a diamond glass coating. This offers superior corrosion resistance when compared to basic, glass-lined geysers. This coating also helps the heating element very durable and effective against corrosion especially when working with hard water. If you are wondering which water heater will work best with hard water, you could easily try out AO Smith.
  2. Digital Display: While most Indian-made geysers save money on manufacturing and do not allow you the use of a digital display, AO Smith has a different policy. For them, more the information and features, the better the appliance itself. Therefore, AO Smith geysers come with a digital display that shows you the temperature and even the energy consumed by the geyser.
  3. Remote Control: One of the best parts about AO Smith geysers is the remote control they come with. It may sound like a very basic addition, but a remote really helps you go hands free and save a bunch of time as well. Plus it is kind of cool to switch on a geyser using a remote control.
  4. Suitable for high-rise buildings: If you know about purchasing geysers, you understand that bar pressure is an important aspect to note if you live in high-rises. This is where AO Smith excels, since all their models come with at least 8 bars of pressure which is perfectly aligned for use in high-rise buildings.
  5. Air2Heat: Since AO Smith generally only manufactures water heaters and boilers, they have made some incredible developments when it comes to geyser technology. One such is their Air2Heat technology that can help you save a ton of electricity and quicken the process of heating. Essentially, Air2Heat models generate heat from the environment, and only transfer it from one part to another, slowly heating the water in the process. This way electricity is not used directly to heat the water, thus saving you a lot on electricity bills and such.
  6. Adaptive Energy Savings (AES): AES is great to save you money and time. AES is a feature that analyses your usage patterns and figures out your when the geyser should start heating the water using the Air2Heat method. Essentially, if you tend to switch the geyser on at 7AM everyday, the appliance will start heating the water just before the time.
  7. All-Around Protection: AO Smith geysers come with protection from corrosion, excessive pressure, and the rest. The element itself is also much more durable than the ones you find in other water heaters. This alone is a great reason to get yourself an AO Smith geyser. The safety valve is great against high pressure and keeps it from damaging the appliance.
