Mini Digital Water Heater

The most powerful hot water solution to date

The mini is perfect for those who love their long showers

Touch screen panel

The control panel tells you the real time quantity of hot water in the heater tank. Use the panel to lower your thermostat an energy saving level of 50ºC to save energy.

The only instant-storage heater in Singapore

With an unparalleled hot water recovery rate, the mini generates hot water 2.5 times faster than a first generation electric water heater. Get hot water instantly.

A sensor at hot water outlet detects your hot water requirements the minute your faucet goes on.

HOW MINI COMPARES TO GEN 6 >

Same tank size, 600% better performance

The mini water heater easily outperforms a first generation water heater.

1st gen 40 lit: 8 minutes of hot water
8th gen 40 lit: 24 minutes of hot water

GEN 8 MAX HEATING >

Intelligent Maintenance Monitor (IMM)

Patent ZL201210318688.9

The mini monitors tank ion activity in real time. When corrosive ions cross a threshold, users are prompted to perform maintenance on the heater. This effectively maximizes the tank lifespan.

What is the difference between digital gen 8 and digital gen 6?

Gen 8 is equipped with more advanced technology and its performance is better.

Speed heat time from full cold tank:
Gen 6: 2 min
Gen 8: 0 min

Run-time of hot water in minutes:
Gen 6: 16 min
Gen 8: 24 min

How does IMM prolong the life of my heater?

Intelligent Maintenance Monitor or IMM, actively measures the level of corrosive ions in your tank and prompts you when maintenance is required.

Regular maintenance will prolong the lifespan of the water heater.

What maintenance should I do and when?

There are two maintenance types. Safety maintenance should be done every 3 years after the initial AOS Bath 3-year warranty.

A tank flushing is recommended every 5 years. This helps to keep water in the tank and sediment free.
