Why We Love the Micro Heat Pump!
I got an AOS 80L micro heat pump recently to replace my electric heater.
My electricity bill has been reduced by a lot and also have never run out of hot water since the installation due to the large tank.
Not to mention my toilet is much cooler due to the cold air emitted from the heater when heating the water.
Highly recommended!

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.

I am a return customer of AOSBath.
The most recent purchase was for the heat pump water heater, which promises to be energy efficient. One thing is for sure: I enjoy the cool air exhaust a lot and I find myself sitting/standing near the heater when it is in operation a lot.
1st purchase was for a digital water heater and it worked reliably over 6 years. I have also recommended my sisters to get the same heater and they are happy users as well!

Make Your Dollar Work Three Times Harder
For the same amount of money, heat pumps give you 3 times more hot water.
New Tech, Now Micro Sized for You
Once, heat pumps were only used in large buildings. Today, they are small enough to fit in your home.
Are micro heat pumps suitable for your own home?
Reduce Long Wait Times to ZERO
Planning on having several showers at one go? Heat pumps can handle that without breaking a sweat.
If you're connecting sink taps and other basins, the heat pump will serve the entire family's needs all at the same time.
Few years back I read an article on Straits Times on the advantages of heat pump over solar water heater. I kept it in mind and finally when I bought a landed house, I decided to engage AOS Bath to install AO Smith integrated heat pump... Finally, my electricity bill is low and I am happy that I am able to use renewable energy.

Authorities Want MORE Heat Pumps in Homes!
Rejoice in The Micro Heat Pump's Free Cooling effect
Bet you didn't know that heat pumps can emit cool air while they are working.

Where's the best to fix your heat pump?
Knowing Gives You Absolute and Full Control
Forget the days where you have to guess how much hot water is left in your water heater. Erase all ambiguity with easy hot water visuals.
Now you know exactly how much hot water is available before you even step in for a bath.
Don't get a Low-end Heat Pump Which Only Lasts 5 Short Years
When you buy a heat pump, you're in it for the long haul. You want a good tank that can last you around 10 years.
A. O. Smith's Blue Diamond tank has been a market leader for over 100 years. Why? Their high durability tank has an impressive track record of a 52 year lifespan!
The Inverter Micro Heat Pump is 30% More Efficient than Other Heat Pumps
Just like an aircon! Did you know heat pumps have inverter and non-inverter versions?
Inverters have higher technology and precise motor control. This means you get lower power consumption and quieter operation!
I love the AO Smith heat pump. Have been using it for 5 years now without any issues, hot water throughout the unit anytime of the day. Low upkeep price as it uses little electricity. Highly recommend this, and you'll see ROl in less than 3 years.

Alhamdulillah! Kalam and Sumon did an amazing job, and we were really hoping against hope that, insya'Allah, the heat pump would fit!
I'm excited for more climate-friendly and comfortable showers! No more dealing with intermittent hot water or waiting for turns like we did with our gas heater.. After three years of waiting, this upgrade feels like a blessing!

Micro Heat Pump FAQ
What can the remote control do?
The remote control is for heat pumps installed above false ceilings.
Use the remote control to program your water heater.
After the initial set up, there is no need to always adjust the panel or use the remote control.
You can power on and off at the main heater switch outside your bathroom.
How often should I maintain the heater?
You should perform a maintenance every 3 years. This comes with a tank flushing to clear out any sediments in the tank, keeping your shower water clean.
Keeping a clean tank also prolongs the life of your water heater.
What is AES and can I use it?
AES is an automatic timer function.
Due to Singapore’s warmer climate, AES has been known to restrict the heater’s heating cycle. You are advised to disable the AES function.
My heat pump is drips water, is this normal?
Yes, it is normal. Heat pumps produce condensation and water droplets from the relief valve.
All drips should pipe off to a proper drainage. The dripping should not wet your false ceiling.
What is the warranty like?
At AOS Bath, we’ve got you covered with the most extended onsite warranty for water heaters in Singapore.
And here’s the best part—it’s a complete onsite warranty with no extra costs from your pocket. This means you’re fully covered for three years, including transport, parts, and labor.
