Heat Pumps: The Undisputed #1 Landed Choice

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.

It's a fact. Your Heat Pump is only as Good as Your Service Support Team!

Only commit to professionals when investing in a high cap heat pump.
I have been sourcing for a thermal pump water heater to supply to my house for reason of long term running cost and reliability.

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 prying eyes away from your private spaces

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:

Make your Bathroom Space Look Larger than Life

Our heat pumps are weather proof so make FULL use of that feature and install it outdoors. This frees up precious internal living 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 an easy to access public space - at the roof or aircon ledge. This keeps the messy installation works far away from your living areas.

When you require a service or maintenance, installers only need to access these places.

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 installations

Eliminate your worries about falling objects or damaged items in your personal space.

Forget about the exorbitant costs associated with cutting ceilings, plastering, and patching. 

Find out how to upgrade to a stress-free, elegant solution today.

Revolutionary Technology in a tiny package, small enough for your personal use

Heat pumps have evolved beyond our wildest dreams.. it used to be that giant systems were only available for large hotels and businesses. 

Today, the latest technology has made this energy saver available to home owners. Heat pumps are now neat, easy and low-maintenance.

Find out the best placement for your heat pump by sending in your floor plan. We'll 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. 

Find out how you can get free cool air today!

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.

Something 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.

Large Landed Properties with over 5 Baths.. Energy Saving Heat Pumps Will Save you Thousands!!

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 are Authorities so HYPED about 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!

Don't delay saving money! Start accumulating 80% of heating costs in your bank now. We can help!

Here's a Secret Hack To getting your Heat Pump working for You 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.

I am using the AOS heat pump (180L), water purifier, hot water dispenser and pre filter.

If you have a circulation loop, you need a circulating pump to pump hot water around the loop.
Solar heaters have high-power backup heating elements. There are often activated when conditions are unfavourable. These conditions include rainy days, cloudy days and evenings. When heating elements activate, solar heaters are low efficiency.

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.
