Best Water Heater in Singapore

1. A. O. Smith Gen 6 Digital Water Heater

Singapore’s first digital water heater: Energy-efficient, enjoyable showers

Having a storage water heater is a lifesaver. It means having hot water supplied to multiple bathrooms at high water pressure. However, storage heaters of the past are high-consumption guzzlers as they heat water to 70°C. Users have no option to reduce this.

Enter Singapore’s first-ever digital water heater, the A. O. Smith Generation 6 (Gen 6). The Gen 6 is a digital heater that comes with its own control panel. This panel allows you to program your heater according to your family’s needs. You can even reduce the heater thermostat at the touch of a button to save energy! The recommended setting for Singapore is 50°C.

Now you can do your part and change your habits. Lower your thermostat and save up to 10% energy while enjoying your shower. Saving energy is important in Singapore, where electric tariffs and costs are on the rise.

Multiple back-to-back morning rush showers? No problem.

Despite its smaller size, the A. O. Smith Gen 6 Digital Heater can also supply 2 times more hot water than a regular electric heater (Gen 1). This is due to its patented MAX Heating technology.

The smallest Gen 6 tank is only 40 liters and fits well in a BTO bathroom, but don’t be fooled by its size. The digital heater produces enough hot water to allow your family to take 4 back-to-back showers. This is perfect for accommodating your morning rush hour.

Speed Heat: Get hot water almost instantly

Another thing we love about the A. O. Smith Gen 6 Digital Heater is how it allows us to heat water almost instantly.  At the touch of a button, you can get hot water from a 100% cold tank in just 2 minutes! Currently, there are no storage water heaters with this amazing speed heating ability. In the past, storage heaters needed at least 20 minutes to heat up. We are incredibly impressed with this new technology.

Did I mention you could set a timer? The A. O. Smith Gen 6 Digital Heater even comes with its own built-in timer. Get your warm water ready for you when you step into your bathroom as early as 6AM. You never have to worry about forgetting to switch off the heater when leaving home. The timer automatically shifts your heater into energy-saving mode for you.

A reliable 150-year brand, the #1 Water Heater in the USA

Having the A. O. Smith Gen 6 Digital Heater makes life so much easier for us. After all, it comes from the largest water heater manufacturer in the world. For 150 years now, A. O. Smith has outperformed industry durability with their famous patented Blue Diamond tanks.  Those patents are why they have a reputation for lasting well over 10 years.

In Singapore where water is really clean, the longest-lasting AOS heater ran an impressive 28 years with zero issues. This is a true testament to their leadership in technological innovation. Though A. O. Smith heaters are on the pricier side, their technologies are well worth every penny.

What we love about A.O. Smith Gen 6 Digital Heater:
  • Longest onsite 3-year full warranty
  • Digital control panel for convenient and eco-friendly use
  • Compact 40L capacity

Rheem’s Xwell Classic Plus Electric Storage Water Heaters are fitted with an exclusive RheemFoam™ insulation, a high-density and top-grade polyurethane foam that provides 16% more heat retention. This means that water remains hot for a longer amount of time in the inner tank, leading to reduced heating cycles. They are also equipped with the RheemHot+™ Diffuser which regulates the incoming flow of water into the tank so that heating is optimised, resulting in 45% more hot water for your hot showers. With less waiting time and more hot water, your showers will be much more enjoyable, be it on a rushed morning or on a tiring night after a busy day.

Safe for the entire family

While taking hot showers is a relaxing and comfortable experience, there may be the fear of scalding especially if you have children or elderlies at home.

Built to last 

Naturally, when buying home appliances, you would want to invest in something that is durable and reliable. Rheem’s Xwell Classic Plus Electric Storage Water Heaters do not disappoint in this aspect. They are built with a RheemHD+™ sacrificial anode rod that is placed inside the water heater tank. The sacrificial anode rod allows aggressive water to attack the anode rod before the walls of the inner tank, so if corrosion were to happen, it would occur on the anode first.

To enhance energy efficiency, consider insulating your water heater tank, setting the thermostat to an energy-saving temperature, and installing energy-efficient models. Regular maintenance, like flushing the tank and checking for leaks, can also contribute to efficiency.

Are there any safety precautions I should take with my water heater?

Yes, it’s essential to set the water heater thermostat to a safe temperature to prevent scalding. Regularly check for leaks and ensure proper ventilation for gas-powered heaters. If you notice any issues, it’s advisable to contact a professional for repairs.

How long can I expect my water heater to last, and when should I consider replacement?

The lifespan of a water heater varies, but on average, it can last between 8 to 12 years. Signs that your water heater may need replacement include a decline in performance, increased energy bills, or visible corrosion. Regular maintenance can extend the lifespan of your water heater.


In conclusion, navigating the realm of water heaters in Singapore involves careful consideration of factors such as household size, energy efficiency, and available space.
