AOS Heater High Density Insulation
24/7 Energy Saving, No Maintenance Needed
High Density Foam will save you Hundreds of Dollars!
Almost everyone avoids the topic of insulation. That is because it is the perfect place to cut corners without you noticing! This is why you should pay attention.
If you have thin insulation, be prepared to lose 50% of your tank heat in 4 hours. But if you have good insulation? You only lose 8%.
Most people forget.. that a tank has TWO functions, not one.
You win the game if you can:
• heat water AND
• keep the water warm
Most people forget about the second part. Your heater should be good enough to retain heat like a thermos flask.
High density insulation like in an AOS heater is not easy to achieve. You can only get this kind of foam effect in huge, fully equipped factories.
Beware of cheap and ineffective styrofoam insulation
This is an actual cut out of a water heater we replaced in Singapore. It is insulated with styrofoam, the kind that is used to make huge boxes.
This foam is low-cost. That makes the heater cheap. But be careful, because 'cheap' can cost you more in the long run.
Look at all the gaps in the insulation! Styrofoam has a low R-value. Your heat will leak out like a flood, and you'll be stuck.. wondering why you have to keep waiting for hot water, day after day.
Been using another brand of heater for over 5 years and always felt that the insulator is not working well, the heated water always cools off by morning time. After using AOS, there is definitely difference in insulation and the water remains warm even 24hours later!

What are R-values and how can they help me save money?
The R-value measures how good insulation is. For best results, you want high R-values.
The R-value of styrofoam is 3, it is light and easy to carry around. This type of insulation is good for temporary use, like packaging food. You don't want this as your heater insulation.
The R-value of AOS heater insulation is 6. A similar kind of foam is used in high-quality wall insulation.
Super cool stuff like aerogel has an R-value of 10.. but it is crazy expensive. You don't want your water heater to cost $10k 😅
Eeeeek! Black mould can grow on styrofoam?
Styrofoam has an open-cell structure that absorbs moisture. That is terrible for Singapore. With high humidity, mould is our enemy. You don't want mould growing in your heater.
AOS high-density foam is anti-mould. It has a closed-cell structure that rejects moisture. Your insulation will stay clean and mould-free for years!
High density insulation has micro heat-trap bubbles
Here's an inside look at how foam is injected into the heater! It expands to fill every gap. Then it hardens into a dense, solid layer.
Not only does this keep your water warm. It is also ranked high in safety because the sold foam offers extra stability to the heater.
Foam traps air. Millions of tiny gas bubbles are sealed inside each foam cell. These air cells slow down heat transfer.
I have chosen AOSBath Digital due to its thicker thermos insulation and the instant water function. It has been 6 months of use now. Some times I forget to switch on the heater but it still delivers hot water. We are glad to have found AOS, and I am happy with the decision.

The water heater is amazing. Hot water that never fails. It can keep hot water for long periods of time. Saving me some money of not needing to switch it on again.
