What’s the difference?
What are the Group A Technologies?
Group A technologies are basic durability technologies. They are the pre-requisites to build a heavy-duty, heating machine. Every AOS water heater builds upon these technologies.
Blue Diamond tank: This special tank lining formula allows AOS tanks to last for over 10 years. The average lifespan of a water heater in Singapore is 5 years.
Blue Diamond element: These patented elements are anti-scale and anti-corrosion. They operate at high efficiency even after 10 years of use.
Low-disruption inlet: These inlets prevent high incoming water pressure from creating turbulence in the tank. This allows you to get a steady flow of hot water.
High density insulation: Other brands use 2cm of styrofoam. AOS uses 2 inches of high density expanding foam that leaves no air spaces in the heater jacket. This allows AOS heaters to conserve heat like a thermos flask. Less reheating means more money saved for you.
What are the Group B Technologies?
Group B technologies are digital technologies. With a control panel, you can tell how much hot water is inside your heater and control the way it heats.
Instant heating: Back from a vacation and need a shower right away? Gen 1 heaters make you wait 20min, but get hot water in only 2 minutes with a Gen 6 heater.
Built-in timer: Do you often forget to switch off your water heater? Timers can help to power off your heater when not in use.
MAX heating: In the past, Gen 1 electric heaters could only give you 2 showers. Now, digital heaters Gen 6 or Gen 8 can give you more hot water, up 4 to 6 showers.
What are the Group C Technologies?
Group C technologies harness renewable energy to save heating costs.
Heat pumps: Heat pumps are innovative systems that use free heat from the ambient air to heat up water. They save up to 80% or $600 a year compared to Gen 1 electric heaters.
Automatic timer (AES): No programming required. Your heater goes into energy saving mode when not in use.
