Besides homeowners, we have also helped several discerning businesses to achieve their desired hot water results.

Want stellar results?

It is the first step to getting the dream shower for your home.

Everyone starts off unsure of where to begin.

Here is your first tip.

Big tip #1:

Do not take the advice of your neighbour, friend, mother, designer, contractor or whoever else that has all these good intentions in store for you. Good intentions are aplenty, but that will not help you.


Because it is your house. It is your decision. No one understands what you need better than yourself. No one can do it for you.

You need to make your own decision

Do yourself and your family a huge favour and take your own water heater quiz.

Your customised water heater quiz results ensure you get a 95% accurate water heater recommendation based on your own UNIQUE set of:  

  • Bathing patterns
  • Morning rush usage
  • Water pressure preference
  • Bathroom layout requirements

2 minutes can save you years of regrets

You can see how this varies vastly for everyone.

It is all too easy to make one wrong decision and end up with the incorrect heater.

It is a mistake some people live with for the next 5 years.

Save yourself the trouble and avoid the mess with a simple 2 minute quiz.

It’s your new home. You want it to be perfect. Don't be forced to live with a lemon that can’t meet your basic everyday needs.

Hi, I’m Amanda from AOS Bath.

Today, let's talk about lemons.

Specifically, water heater lemons. Lemons are products that come in all shapes and sizes, but they have one thing in common.

They are products that do not work as advertised and they will drive you up the wall with: 

If you were to watch the video all the way at the top, you will learn why we only focus solely on educating homeowners over everything else.

Do your own research.

Define what you need,

Or you won’t know the right heater to get.

I’ve spent around 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 seen most homeowners leave this simple first step to contractors or bathroom retailers because they have no time. Sadly, the experience pretty much goes south from there. 

Avoid this mistake!

Why I understand your frustration, confusion and experience.

I don’t blame you. I can understand because just several years ago, I was there 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 a disaster. 

But people learn from the mistakes of others, and I’m hoping that my sharing today will help you avoid that too. I now take 5 minutes to study my own needs 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 and recommendation. 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 over here.

House-renovation is a black box.

There is a lot of dishonesty and distrust in the market, and I just want to make sure you don’t fall into those traps like I did.​

It makes me sad to hear horror stories from homeowners who could be treated so much better and with more respect.

I’m quite sure you’ve heard of..

The list can go on but it is just making me depressed, so I’ll stop here.

The bottom line is at AOS Bath, we exist to combat all the untruths and inaccuracies of a very messy marketplace. We do this best by educating you, the homeowner to make your own choice.

Good things begin slowly and from the ground up.

Sure, the entire process will take longer and we need to give you more detailed explanations but that is alright with us, because the main objective of our business is not to make money. Instead, it is to ensure we deliver happiness with your water heater at the end of the day, and that the hot refreshing shower you take gives you joy and washes your stress away. 

In all things I do, I ask myself this.

If the roles were reversed, would I hope to be treated the same way? 

This helps me to sleep well at night, but don’t simply take my word for it. See for yourself how AOS Bath became Singapore’s Highest Rated Water Heater Company.

Let me tell you a story. Tom is a layman homeowner and knows close to nothing about water heaters. To order a heater, he:

  1. Did a quiz to find his perfect heater
  2. Bought the heater online (everyone does that now, because covid)
  3. Arranged for an installation

Much to his surprise, the heater arrived but could not be fixed as his place was too small. 

Luckily, the other smart thing Tom did was to purchase his heater with AOS Bath. AOS Bath understands that homeowners cannot possibly know if the heater will fit. So they activated the 100% Installation Guarantee, took the heater back, and offered Tom a full refund. Case closed.

Did you know that water heaters are the second largest energy consuming appliances in your home, after the air conditioner?

The performance of a renewable energy heater is largely dependent on its operating climate. There are two main renewable energy water heaters types in Singapore. First, solar heaters which get free energy from the sun and second, heat pumps which absorb free energy from the ambient air.

Climate research has shown that the sun intensity in Singapore is low due to our proximity to the equator and subsequent cloud cover. The cloud cover affects the solar heater absorption rate such that its efficiency is lowered to 50%. Heat pumps on the other hand, benefit from our constant summer-like climate and enjoy a resulting efficiency boost to around 80%.

Today, heat pumps are used by over 70% of businesses and hotels in Singapore.

With Singapore’s latest renewable energy initiatives, this figure is increasing.

As a leading supplier of heat pumps in Singapore, we were featured on Channel News Asia.

Some clients like to make decisions guided by price, dropping thousands on the most advanced models without fully understanding what benefits they bring. Allowing you to make a decision this way is not correct and frankly, makes us a little uncomfortable.

Do not be surprised if we propose lower priced, more suitable alternatives for you. Our main concern is not how much you purchase. Our service levels to you will remain the same regardless of your purchase. We are more interested that you find a heater that serves your unique needs well for the long term.

You don’t have to be rich to be clever.

To find out which is the best-value solution for you.

Real technology vs. Fake technology

The concept of ‘Fake Technologies’ may come across as a strange idea but the truth is we’ve all had an experience with fake technologies before. Fake Technologies are just systems that don’t work as advertised.

What are REAL technologies?

You don’t have to be rich to be clever.

the first digital water heater in Singapore was sold. It could:  

  • Produce 1.5 times more hot water than an electric heater and
  • Produce hot water 2 times faster than an electric heater

In 2021, the most advanced digital heater in Singapore can

  • Produce 6 times more hot water than an electric heater and
  • Produce hot water 8 times faster than an electric heater

These are REAL technologies with REAL patent numbers that have progressed over time with the support of an active R&D unit.

What are FAKE technologies?

In the span of 10 years, many digital-like water heaters have emerged in Singapore. These heaters may look like digital heaters because they come with a control panel but their performance is far cry from real digital heaters. 

I consider these Fake technologies because they are designed to mislead the unknowing layman homeowner. 

Common characteristics of Fake digital heater technologies include systems that: 

  • Cannot produce more hot water than electric heaters
  • Cannot produce hot water faster than electric heaters
  • Come equipped with low functionality features like Wifi which end up increasing your time spent using the product instead of freeing your time up
  • Are commonly manufactured in an OEM factory and not by the actual manufacturer
  • Have short lifespans of about 5 years 
  • Frequent breakdown of parts 

It is disappointing...

Some big brands employ OEM factories to produce these FAKE technologies in the interest of getting more short term market share. We dislike this practice because we believe that the client’s interests should be protected for the long term.

Short-sighted practices bring down the image of the water heater industry as a whole and create a low-trust environment that is more difficult to operate in the long term.

How can you identify real technologies from fake technologies?

When shopping for appliances for my own home, I find that these steps can be easily applied across most product categories including water heaters to set apart Real from Fake technologies.

#1. Read the reviews

Be very aware of companies who have disabled google reviews. Honest client feedback is important so why would anyone do that?T

#2. Ask for reports

Independent third party vendors can verify a system’s performance for a fee. A trusted retailer of real technologies should be happy to have their systems tested and have these reports on hand for you.

#3. The brand has a good track record

How long has this brand been in the market?
Are they top in their category? 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.

#4. Specialists or Generalists?

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.

#5. Patents

How many patents does this company file? 1 or 100? Do they talk about having a dedicated R&D unit? Companies with no R&D and in-house manufacturing usually shy away from the mention of patents simply because there aren’t any technologies to protect.

Take a heater quiz

Thanks to the internet, a quick background search to verify these key factors should only take you a few minutes. These few minutes of research are worth your time.

Still not convinced? Read about our client’s experience.

Research is education

Thankfully at AOS Bath, we make research easy for you with simple infographics and well researched results, all this specially for the Singaporean household.

Buying a heater for the first time?

First time buyers, you really need to know what heaters are suitable for you. Whatever you do, do not take the one-size-fits-all recommendation from your contractor. Some shortcuts really do lead you to the wrong place. Instead, take 2 minutes to find out your unique heater type with a short quiz.

Frequently asked questions (FAQs)

For apartments, a good time to order your heater is at least 3 months in advance. For landed homes, at least 6 months is advised. Fix the decision on your heater early as the heater choice affects:

  • heater placement
  • laying of pipes
  • ceiling height drop
  • whether you can use rain showers or bathtubs

Covid Update: Recent container hold-ups can delay shipments up to 3 months. To avoid disappointment, you are advised to reserve your heater ONE month earlier than scheduled. Popular 40 lit digital does go OOS. You can downsize to 40 or upgrade to 50.

HDB (no false ceiling): Fix your heater as soon as your floor and wall tiles are up, during the renovation stage. The installation process involves drilling and it will get dusty.

Landed and Condo (false ceiling): Fix your heater before the false ceiling is up to avoid extra false-ceiling work charges. This should als be in the renovation stage. 

Landed (roof): If you are using a central heater, the most common installation location is on the roof or close by your aircon compressors. Start installing the heaters as soon as the structure is up. Use of a crane may be required.  

Yes, you may use your own installer. We will provide additional guides on top of the instruction manuals for clarity. Most experienced installers can follow these guides without a hitch. Your warranty will not be void if the heater is installed according to the guides. 

We provide homeowners with a 4-Point Installation Checklist for you to verify that the installation was done correctly.

Certainly. Most homeowners pass us their contractors or IDs contact details right after the purchase. We will take care of all the coordination from there so that your time is freed up for more important decisions.

If just got your keys to a new BTO estate, there may be a group buy going on (minimum 10 pax to fly) 😀 Otherwise, you may start your own group buy. It is very easy, we keep track of all the numbers for you. 

We also have heater bundle promotions with AOS water filters. They are an excellent pairing to keep your tank water clean and prolong the life of your heater by 30%. Do check them out on our online store.

HDB installations supervised by Licensed Plumbers should cost at least $250. 

If you are doing a bundle deal with your ID or contractor, they may charge you less. If they are trusted installers, go for it. 

There have been many instances of one-off contractors installing heaters for $100+. Spring Singapore has repeatedly issued warnings about such unlicensed installers. The heater is a high wattage appliance. It is wise to keep safety as a priority over cost when making a decision.
