AOSmith Heat Pumps for Landed Homes
In Singapore, Heat Pumps are more efficient than solar heaters. Use free air heat to save hundreds of dollars each year.
Huge Households risk of having High Maintenance Heaters
If you have several bathrooms, installing each area with energy guzzling high consumption out-dated water heaters will devour your energy and money.
This is where heat pumps come to your rescue. Watch how this sleek and powerful technology transforms your heater into an efficient cost saving machine.
Take Down Sky-high Electric Bills
Heat pumps use a whopping less 80% energy than a traditional electric powered water heater.
How? They are powered by a tiny fan that draws in 100% free heat from the ambient air.
You're not creating new heat, you're just tapping into 100% free resources from the environment.
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.

Have been using the heat pump water heater for 6 months. It's possible to use climate change voucher for it. Idle power stands at 4w only, so you can always on it without worrying about eating too much power. Its large tank is also good if multiple bathrooms use the hot water simultaneously. Overall, it's the best heater l've used and totally no complaints.

Heat Pumps: The Top Choice for Landed Homes
At AOS Bath, we highly recommend going green with Heat Pumps.
Using renewable energy is the only real way of saving energy because you are using free and clean sources which are ALREADY available in the environment. Other gas and electric sources run on fossil fuels that don't save our earth.
The Heat Pump will deliver great hot water pressure, 5-star showers and baths, all while saving the earth.
How to do this?
Heat Pumps reduce your water heating bills by 80%
Heat pumps transfer heat from the outside air to your heater, providing hot water at a fraction of the running cost of an electric heater.
AOS installed their 180L outdoor heat pump on my flat roof in Feb 2024, replacing a 300L solar heater.
The Company is very capably staffed, every tech and administrator is well versed to address all queries and situations. I do not see many building equipment suppliers as attentive and technically able as this one.

I researched and chanced upon AOS in Singapore and I was sold when I visited their office. The sales person/Ada has been very helpful in answering and responding to my questions and also working around the delivery and installation schedules according to my house renovation stage, all in the thick of the Covid pandemic; kudos to the team!
For record, I bought an integrated 180L thermal pump system (HPI-50D), along with circulating pump Z25-6 and the pre-filter.

Keep Your Space Private
When you install a central heat pump, it will be out of sight and far away from your personal areas.
If ever a service is required, you never have to worry about a stranger entering your bedroom or personal bathroom, and looking through your pictures, clothes, or mess. What's yours, stays yours.
Find out how to keep your privacy:
Weatherproof Heaters Save Space
Our heat pumps are weather proof so make full use of that feature and fix it outdoors. This frees up precious space.
Because your water heater is no longer in the house, you can now raise the bath ceilings to max height to create a spacious concept.
Central heat pumps should be installed in a public space. Good spots are the roof or aircon ledge.
This keeps the messy installation works far away from your personal area.
If your heat pump needs a check, we can get to it easily at the roof.
This is just one of the useful tips we've observed and picked up from the thousands of architects and designers we've worked with.
Say Goodbye to the Chaos of Ceiling Works
Don't worry about falling objects or damaged items!
Forget about the high costs that come with with cut ceilings, plaster, and patch work.
We can help you upgrade to a stress-free, easy solution today.
High Tech in a Single Tank
Heat pumps have evolved beyond our wildest dreams. Once upon a time, these high tech systems were only for large hotels and big buildings.
Today, this Energy Saving Tech is ready for landed home owners. Heat pumps are now neat, easy and low-maintenance.
Send us your floor plan and will give you a no obligations quote right away.
Get FREE Cool Air, and SAVE TONS of Energy!
Here's a cool fact. Bet you didn't know that heat pumps are air conditioners working in reverse.
The big difference is that while air conditioners struggle to work in Singapore's hot climate, heat pumps effortlessly extract abundant heat from our air to heat water at very low power consumption.
This time-tested, proven technology that has been working money saving wonders! It is 4 times more efficient than a normal water heater.

YIKES! A Poor Quality Heat Pump's efficiency can drop from 80% to 40%??
We're here to make sure that you don't get shortchanged like that. It's important to get a heat pump from a reputable, top ranking brand.. We trust AOSmith.
Backed by over 150 years of experience and integrity, an AOS heat pump is a high fidelity system with an extremely long lifespan of over 10 years. It also retains its high efficiency over many years of use.
Investing in a good heat brand will save you thousands of dollars in the long run. Don't compromise on quality.
2025 Efficiency Update
If you have a central heat pump, you are likely to have a circulating hot water loop. This hot loop runs around your house. The good part: It helps you get hot water fast.
The bad part: it costs around $1k/ year to run. (Semi-d, 3 baths) We recently designed a new AI device to reduce this by 70%. That's $700 of savings a year! All our central heat pumps have this new gadget now.
What they don't tell you about solar heaters
Solar heaters don't work over 50% of the time. They don't work at night, on hazy days or even on rainy days! In their down time, solar heaters transform into 300-litre, high-wattage, high energy consuming electric heaters without you knowing. But heat pumps don't give you that problem. They run at high efficiency as long as it is 15ºC and above.
Because of this, we've replaced many solar heaters to heat pumps for hundreds of satisfied customers!!
Got a solar heater to replace? We'll give you some solutions.
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 to supply hot water to all 5 bathrooms in my house.
The entire engagement with AOS Bath has been very professional. They are always willing to explain the details and clarify all doubts. They also offer advices specific to the individual needs. For example, they advised me to opt for a circulation pump so that I do not have to wait to get hot water in the farthest bathroom. I did that and now I get hot water in 3 seconds.
They worked directly with my renovation contractor to get the installation completed on time. When I moved into the house, they sent a technician to explain the settings in the control panel. By the way, I did not have to touch it after the initial setting. Finally, my electricity bill is low and I am happy that I am able to use renewable energy.

Low Quality Heat Pumps get Super Noisy over Time
Is it really worth annoying the neighbours with your loud and noisy heat pump? Absolutely not! Everyone deserves peace and comfort when they return home.
Heat pumps of poor quality wear down faster and the compressor can go as loud as 90 decibels! That's as loud as a hairdryer. Here is where AOS heat pumps shine, they are built with silent compressors that never exceed 50 decibels.
Being considerate will keep you and your neighbours on good terms for years.
Why does SG Government Love Heat Pumps?
Electric and gas heaters consume 3000 watts of power. Heat pump use only a fraction of that.. just 400 watts. That's why heat pumps are getting so much attention!

Secret Tip to Get Your Heat Pump Working Harder than Ever!!
While heat pumps use air heat to create hot water. If you place them close to your air con compressors, their efficiency increases.

Fast Service is Critical to Smooth Operation
I am using the AOS heat pump (180L), water purifier, hot water dispenser and pre filter. I am very happy with their products and service from the time when I first went to their showroom right till the complete installation of all my products.
Ada and Felicia they were very helpful, friendly and quick to reply with details to many of my queries over phone calls, emails and messages. Kalam, Luke and Bee Lim - the technical team were also friendly, helpful and very professional in their installation service. They were very patient and made multiple trips to help resolve my issues.

It's been 3 years since we started using the HPI-50D and it has brought our household much convenience with its supply of accurately controlled hot water.
AOS reminded me of its need for servicing recently and we are thankful for our service staff today - KALAM - who was thorough and meticulous. He worked tirelessly under the hot sun and still took time to explain to us how to optimise the use of our water heater system. Thank you and Kudos to AOS Bath!

Landed Heat Pump FAQ
Do I need a circulating pump?
Almost 95% of landed homes use a circulating pump. Hot water from the heater will run in a circulation loop around the house. Each bathroom will tee off from the loop to get hot water fast.
A circulating pump pumps hot water around the loop. This pump does not increase or decrease your water pressure.
Without a circulating pump, each bathroom will have to wait several minutes for hot water!
