I did my research and came across AOS product by myself while I was planning for my house renovation. What convinced me was that their quality of they of commercial level. Even their most affordable electrical heater spec can be compared to other brands highest quality.
I was served by Sanny! Extremely happy with his service and product knowledge. He is really helpful and patient with my queries though. End of the day, he helped me in choosing the product and even go as far as to inform me some of the items are unnecessary. Kudos to him for not being pushy at all. In fact all their staffs are not pushy at all.

Purchased the AOS 40L Intelligent Heater in Sep 2020. The sales person who attended to us was very detailed in her presentation of the product, and was able to help us make the best choice based on the usage habits and bath preferences of our small family. Due to renovation delays, the delivery for the heater was only able to be done end of 2020. The installation team was prompt in responding to schedule an installation date, and the installation was done seamlessly. Very professionally run company with great after sales service. Heater has been working without a glitch, and our hot water supply has been steady ever since. Highly recommended product!

Everyone starts off unsure of where to begin.
Here is your first tip.
🔥 Big Tip 1: Don’t Do This! 🔥
Do not, we repeat, DO NOT take heater advice from your neighbour, your friend, your mother, your interior designer, your contractor, or that overly confident uncle at Sunday dinner.
Why?
Yes, they mean well.
Yes, their intentions are good.
But good intentions don’t keep your water hot!
Make Your Own Choice
What worked for them may be totally wrong for you. Different house? Different water pressure? Different lifestyle? Yes!! It all MATTERS.
So before you get swept up in well-meaning advice, pause.
Let’s get the facts straight. it is the KEY to get your setup right.
2 Minutes Will Save You YEARS of Regrets
Take our 2-min Quiz. We will help you figure out exactly what you need.
No guesswork. No regrets. Just expert advice, tailored to you.
Save yourself the trouble and avoid the mess with a simple 2 minute quiz.
I got my water heater directly from AOS distributor. Sales lady explained their products in very clear and concise manner, and I did not have any difficulty choosing the right size and model for my new home. 2 weeks after installation, the heater did not manage to switch on. I texted the sales and she troubleshoot for me to realise it's my wiring which was not installed properly, so I approached my electrician to fix the problem for me. Excellent after sales attitude and expertises offered.

Was looking to replace my faulty water storage heater. Communicated with AOS Bath via WhatsApp and they are very patient in answering my questions and also gave very useful advice.
During installation, the technicians (Suraj and Moez) are knowledgeable, friendly and helpful.
They even highlighted an issue that I had with other appliances when they noticed something is amiss. Did not regret engaging AOS Bath for my water tank storage heater. Highly recommended!!

It’s your new home.
You want it to be perfect.
Don't be forced to live with a lemon.
Hi, I’m Amanda from AOS Bath. let's talk about lemons.
What are lemons!!? Lemons are things that do not work as advertised. Examples of water heater lemons:
🍋 Gives very little hot water. Run out of hot water in 3 mins!!!
🍋 Painfully long waiting times for hot water, especially after a slow hard day of work.
🍋 Dreadful water pressure that transforms your expensive rain-shower into an expensive drizzle-shower.
🍋 Wasted water. Ever turn on the faucet only to have LOTS of cold water flow out for about a minute till hot water FINALLY arrives?
These are all things you MUST know about before you buy a heater. But were you told? I don't think so. This is why we prioritise educating you over everything else!!
Knowledge is Power
Don't define your needs?
Others will define them for you.
I’ve spent over 10 years working with water heaters.
Enough to know that shooting in the dark gives you correct results about 10% of the time.
If you’re lucky.
It only takes 2 minutes to do a simple quiz!
But I’ve too many people leave this simple first step to their contractors or IDs.
Reason? They have no time!!
Sadly, this is the biggest mistake.
I did this too.
Avoid My Mistake!
Have been using AO Smith heat pump water heater (model HPW-80) for the past 9 months. Whole family are very happy with the steady supply of hot water. No more long wait for water to heat up. I am happy I longer burn a hole in my pocket with the high electric bills.

I wish to add that this brand is superb reliable and lasting. The current 72L is a vertical model which has been discontinued and replaced by horizontal model, has been in use for more than 30 years, and never failed me once. The job done by Kalam and Rana team was impeccable. I can tell that they are very experienced in what they do.
Everything was done to my satisfaction including a thorough cleaning of the bathroom before they left. AOS Bath is highly recommended.

This is Why..
I understand your frustration,
and confusion!
I don’t blame you. Just several years ago,
I was renovating my house too.
I trusted my contractor to give me recommendations!
For lights, tiles, and water heaters.
All I did was shop at the retailer list he handed to me.
The result was an absolute disaster.
But you can learn from my mistakes.
I’m hoping that my sharing today will help you avoid making a wrong decision too.
I now take 5 minutes to study my own needs.
This is before even listening to any sales advice or
checking out any promotional brochure.
Trust me, that 5 minutes you spend is worth it!!
For water heaters, this comes in a simple form of a quiz.
Go ahead and try it. I promise you an unbiased result.
The best part is that it is completely no-strings-attached.
You can take that information and fly with another water heater provider.
I just want to ensure you have at least the basics down, like sizing the tank right.
Get the basics right.
House-Reno can be Scary!
So many Sharks!
All trying to make fast money.
Don't fall into traps like I did.
It makes me disgusted.
I hear horror stories every day.
from NEW homeowners who were cheated.
They deserved so much more respect.
I’m quite sure you’ve heard of..
❌ Crappy brands that only last a pathetic 2 years
❌ Dangerous installations where the heater is literally dangling by a wire
❌ Cheap but disaster installers that disappear
❌ Bad plumbing that in leaks and causes massive ceiling water damage
❌ $2500 quotes for a $500 simple job
❌ 3 nerve-wrecking days to finally get through an after-sales service hotline
Oh, we could keep going..
The shady “lifetime warranties” that vanish the moment you need them. The “premium” heaters that break down within months. The sweet-talking salespeople who sound convincing, until you realise they’re just reading off a script.
We’re not here to rant. We’re here to rewrite the rules.
At AOS Bath, we exist to combat all the half truths and gimmicks floating around this chaotic, confusing marketplace. True, it's a jungle out there, but you're not going in unarmed.
We don’t believe in pushing products. We believe in powering YOU with knowledge.
We educate you. We explain. We break things down. We shine a spotlight on every little hidden clause, dodgy shortcut, and misleading claim out there.

Your home deserves better.
So no pressure. No tricks. Just crystal-clear guidance.
When you’re ready to choose...
You can do it with eyes wide open.
That’s our promise to You.
Find the best fit for your family.

Purchased the Gen 6 40l Digital Water Heater 10 months ago. Sales representatives were very knowledgeable and helpful during the process.
Good thing about this product is that i don't have to turn on and off the heater on a daily basis; i just set the timer and I get hot water whenever I shower.

Sanny was very helpful and knowledgeable when it comes to the questions that we have on their products. We left the place happy and satisfied with our purchase. When it came to the installation about half a year later, the people who came did a really great job installing AND explaining to us in full detail how each one worked!

100% Installation Guarantee: Protects You from Pointless Purchases!
Let me tell you a story. Tom just got his BTO keys!! He was clever and read some reviews. Then he decided to go with AOS. Next, he:
1. Did a quiz to find his perfect heater
2. Bought the heater online. EASY!
3. Fixed an installation date
Much to his surprise, the heater arrived but could not be fixed for (insert the crazy reason here) 🚧😵💫 😵💫🚧
Luckily, WE know.. that YOU have no way of knowing if the heater will fit! We quickly activated the 100% Installation Guarantee, took the heater back, and offered Tom a full refund. Case closed.
We Price Guarantee -

Tell us where you found the same product for a lower price, and we’ll refund you the difference. No further questions asked.
While you may be tempted to take advantage of these generous guarantees and just buy our Best Selling heater right away, we do not recommend this shortcut. Instead, we recommend you:
I want to express my gratitude to Ada Goh and her fantastic installers for their exceptional service.
Ada Goh deserves praise for her responsiveness. I initially reached out to her in 2021, and she guided me through the entire process, helping me choose the right unit which I purchased in 2022 and the installation was only recently completed in 2023.
Despite reaching out to them in 2021 and finally installing in 2023, their response time remained remarkably quick. The installers were extremely cheerful and efficient, completed the installation quickly, and patiently explained how the system works, which was crucial for a first-time user like me. Thank you for making the entire process incredibly smooth. I highly recommend their services for both home and commercial

After considerable research on the various storage water heaters, I decided to buy the AOS gen 6 digital heater (40L/10 gal). Right from inception I was served well by the folks at AO bath. They answered all my queries promptly. I also visited their showroom to look at the heaters and ask questions to clear my doubts.
Thereafter I made a decision to invest in the heater. No regrets whatsoever. One of the best investments I have made. It is trouble-free from day 1. Works like a dream right out of box. You can take the product reliability for granted. My family and I immensely enjoy warm baths every day. It is obvious that these heaters have high quality and have a very good quality control process in the back end. I would most certainly recommend the products of this company and given an opportunity I will certainly buy from them again. Good people to deal with. Excellent trustworthy and reliable product.

No hard Sell.
To start, You need to make the first move!!! Take a short quiz and tell us more about what your family needs.
We will use that info to give you a solid recommendation. If you are choosing between two heaters, we'll give you useful advice on what is better for you.
No. We are not interested in blindly recommending you the most expensive product. We want your long term happiness. We want your lifetime satisfaction. We hope you recommend us to others, and that means we must serve you to the best of our ability.

Real Technology vs. Fake Technology
You buy something that sounds high-tech, but then...
it under-delivers. Welcome to the world of Fake Technologies.
✨ Forget flashy features you’ll never use!
🔊 Goodbye fancy-sounding functions!
Fake Tech is designed to impress in the showroom, not in your home.
At AOS Bath, we cut through the hype. We focus on Real Technology.
Interview by CNA on AOS Heater Technologies
AOS Heater lasted 33 years, Chiltern Park, Singapore.
What are REAL Technologies?
It is stuff that actually works.
Not fluff. Not gimmicks. Just pure performance, backed by real-world results.
Take the Gen 6 Digital Heater, for example. Compared to the average electric heater in Singapore, it can:
✅ Produce 2X more hot water
✅ Heat up 80% faster
Another feature? Blue Diamond™ Tank Lining.
💎 Boosts tank lifespan to 10 years
💎 The current record? 33 YEARS!!
💦 That’s insane!! An average heater here in SG lasts only 5 years!
These are not just marketing claims.
These are patented technologies with real numbers, real history, and real impact.
That's how you become the #1 Water Heater in USA.
Get Tech You Can Trust.
🚫 Stay Away from Fake Technologies at ALL COSTS!
They’re everywhere. Cleverly marketed, and Completely Misleading.
Here are a few we seriously can’t stand
❌ Slow "Speed Heating".. even slower than your grandma 🐢
❌ Fake Booster Pumps. They say it improves water pressure. You only find out it doesn’t after you’ve installed it. Too late. Too bad.
❌ Built to Break heaters that barely last 3 years. Total rip-offs!
At AOS Bath, we don't play those games.
We help you choose only real, tested, proven technologies.
I was searching for the best quality water heater in town as my previous water heater was not as good as it used to be. I chanced upon the AOS Bath reviews which most of the customers' reviews are positive and satisfied with AOS products, before and after sales services. Thanks for the excellent sales service staff (his name is Sunny) and also the men who did the installation, they are professional and genuine. Please keep the excellent services. Thank you.

As house owners know, renovation is always a stressful period even with an ID or a good contractor. AOS's professionalism and their high quality products really makes it much much easier. Down at the showroom, Ada was very kind and patiently explained all the features of the digital water heater and filter to us, this ultimately convinced us to buy the water heater and filter from them. Fast forward 6 months later, the water heater and water filter works well without any issues. Heating is fast and can even set a timer, very convenient features. Would recommend highly to anyone looking for water heaters or water filters!

Big, Bad Brands are Disappointing...
Some big brands employ bad, low cost factories to produce these Fake Technologies. Then, people like you and I get deceived. We get fooled once or twice.. but then we get smarter.
These kind of sales tactics are not nice. They won't benefit these companies in the long run. You will eventually find out and never buy from brands that have not been truthful to you.
It is time you take control and start finding out what you need, versus being sold.
How to Spot Fake Technologies?
I follow these steps when shopping for appliances for my own home.
It is easy and only takes a few minutes.
You can use this strategy for your whole reno!
Always works!
#1. Read Reviews
Be very aware of companies who have disabled google reviews. Honest client feedback is important so why would anyone do that?
#2. Buy from Established Brands
How long has this brand been around?
Are they top in their country? If they are so good, why are they not Number One? I also learnt that the country of origin matters. Being ‘Top in America’ is quite different from being ‘Top in Malaysia'. The standards are just different.
#3. Buy from a Specialist, not a Generalist
If the entire company exists to deal with a very specific category, you can be sure they do it better than a company that dabbles in hundreds of products.
You don't want to work with a jack of all trades, master of none.
#4. Patents
How many patents does this company file? 1 or 100?
Do they have a dedicated R&D team? Companies with no research and no in-house factories usually don't mention of patents simply because there aren’t any technologies to protect.

We purchased a heat pump water heater from
AOS Bath and have had a positive experience. They were quite helpful in answering presale questions and explaining the system operation.
The installation was on time and professionally done, and in efficiency mode (the best choice for our needs) there's a big improvement (reduction) in our monthly electric bills compared to a conventional electric water heater.

The water heater from AO Smith is really considered as next gen. As compared to my old water heater, the one from AO Smith heats up really fast and I really love the control that comes with it. It allows me to know how much hot water I have exactly so I can properly time when I need to heat up more.
