Have you been looking through the major water heater brands in Singapore trying to decide if you should get an instant water heater, a storage water heater or a heat pump water heater?

With so many types of water heaters in the market using different technologies and having different features and sizes, you’re probably at a loss trying to find one that will fit your needs and your home.

That’s why we’re here to help. Here are 10 best water heaters in Singapore to solve different problems and meet different needs.

 

1. Gen 8 Digital Water Heater (Mini)

Also known as A. O. Smith Mini Digital Water Heater, the Mini (Gen 8) is one of the bestselling water heaters in Singapore!

Despite its small size (880x340x350mm), this water heater has an unparalleled hot water recovery rate, so you can be sure to get hot water instantly. Simply turn on your bath or shower and the sensor at the hot water outlet will detect your hot water requirements the minute your faucet goes on. All you have to do is wait 10 seconds for 10 minutes of hot water, making this water heater perfect for those who enjoy a long, hot shower after a day of work!

The Mini (Gen 8) heater also comes with a control panel that shows the real-time quantity of hot water in the tank and an Intelligence Maintenance Monitor (IMM) that actively measures the level of corrosive ions in the water, prompting you if maintenance is required to keep your tank water clean and free from sediments. Flushing out the corrosive ions will help your tank last longer.

Pros:

Instant water heating, 5-10% energy saving

Cons:

Panel cannot be detached from the heater body

Best for:

High usage families of four to six members, equipped with rain showers or a small tub

At the touch of a button, this water heater is able to heat up a cold tank in 2 minutes compared to a regular electric heater, which will take 20 minutes.

Unlike electric heaters that only have a standard heating mode, this digital water heater lets you toggle between three different modes for optimal hot water delivery. If you only need hot water for a single shower, you can program it as such to save energy. A regular electric heater can only give you 2 quick showers at a time, but in the event you need hot water for more, the Gen 6 heater can deliver up to 4 back-to-back showers.

This water heater also features a built-in timer so that you can program it to preheat water for you at a specified time. You no longer have to endure a cold shower in the morning or wake up early to wait for hot water.

3. Gen 1 Electric Water Heater

The A. O. Smith Gen 1 Electric Water Heater has an inner tank, lined with a patented formula of Blue Diamond glass by A. O. Smith, making it one of the toughest and most durable tanks worldwide with a lifespan of well over 10 years. The heating element in the heater is also coated with Blue Diamond glass and compared to their steel counterparts in regular electric heaters, these fittings have a 65% higher corrosion resistance. Produced by the only water heater factory in the world that is 95% mechanised, A. O. Smith generates world-renowned consistent performance over years without downtime, trips or repairs.

The Gen 1 heater comes with a temperature indicator that lights up to notify users when heating is in progress. One of the most sought after heaters especially for false ceiling installations due to their long lifespan, this heater comes in a variety of sizes ranging from 30-litres for single showers to 100-litres for long baths and multiple users. You can customise your tank size based on your unique hot water consumption. The most popular size among HDB or apartments with 2 baths in Singapore is the 40-litre heater tank.

4. Integrated Heat Pump Water Heater

The A. O. Smith Integrated Heat Pump Water Heater boasts a revolutionary green technology. This system works by absorbing free ambient warm air, converting it into useful heat and transferring it into the water. This method of heating water will save you over 80% in hot water heating electricity consumption.

Utilising the highest efficiency heat pumps with cutting edge, patented heat transfer technology, the integrated heat pump heater is able to provide centralized heating for up to 5 bathrooms with bathtubs and rain showers. The integrated system is the ideal choice for landed properties. Instead of having individual tanks placed in each bathroom’s false ceiling, all heaters can be unified into a single system. This greatly reduces your overall power load and eliminates messy false ceiling maintenance work in each bathroom. This heat pump is a design favourite as it allows all bathroom ceilings to be raised to the maximum height to create the perception of space.

Due to its weatherproof construct, heat pumps are usually installed outdoors on the roof or next to the aircon compressors. All heat generated in the area around it will boost the heat pump’s efficiency.

The heat pump water heater features temperature controls, a built-in timer, instant heating and several modes including a high efficiency option that can save up to $800 in heating bills annually. Heat pumps are equipped with smart heating functions that allow it to operate automatically.

Pros:

80% energy saving. The more you use, the more you save

Landed properties with up to 5 baths and rain showers

Using A. O. Smith’s high performance heat pump technology, the Light Commercial Heat Pump Heater operates with the highest rated and most consistent efficiency in its category. This system can cater to residences with up to 10 bathrooms and is compatible for commercial use in businesses who are interested in exploring energy-efficient green solutions. The Light Commercial Heat Pump water heater comes with patented microchannel coils that maximise heat transfer and ensure high fidelity performance even after many years of use. Most other heat pumps experience a significant efficiency drop after just 3 years of performance as non-patented heat transfer coils can easily go out of shape.

The system features built-in timers, high-density insulation and a self-regulating automated system that users can leave to run on its own. The heat pump is equipped with a back up heating system that can easily be activated from the control panel.

The Light Commercial Heat Pump Heater is an integrated system, which means it is extremely space saving and does not require a space for a separate compressor. Like all A. O.

6. Split Heat Pump Water Heater

For residences of around 5 bathrooms with tight installation spaces, we recommend the A. O. Smith Split Heat Pump Water Heater. This system uses heat pump technology to convert ambient warm air into energy that heats up your water. The use of renewable energy will save you over 80% or $800 in hot water heating electricity consumption each year.

This split system is extremely versatile and popular for solar heater replacements, where space is limited and difficult to access without a crane. The heat pump’s weatherproof design allows it versatile placement and water pressure is high regardless of whether it is installed on the roof or the basement. Its touch screen panel can be run to a convenient location within the house and users can access energy-saving features using temperature and operating mode controls. The heat pump range is heavily insulated to reduce standby heat loss, and comes with a built-in timer that facilities smart, full automation for maximum convenience.

Split system requires refrigerant top up every 3 years

Smith Roof Solar Heaters apart from other solar heaters are their patented tube solar collectors that can absorb a spectrum of sunlight from greater angles than a flat surface solar collector. Evacuated tubes are a functional design where single tubes can be easily exchanged if there is partial damage, compared to flat panels which have to be fully replaced.

On a sunny day with no cloud cover, solar heaters can produce hot water for up to 5 bathrooms with zero electricity cost. On cloudy or rainy days, easily activate backup elements from the touch screen panel conveniently located in your home to ensure no down time.
