What is so special about Blue Diamond glass?

Blue Diamond glass is a revolutionary formula of glass which fuses itself to the inner heater tank completely, expanding and contracting without cracking or shattering as water cools and heats.

Blue Diamond glass lined water heaters means cleaner, purer hot water because glass cannot rust.

Mrs. Price and the water heater which lasted 52 years

The 52 year ‘Blue Diamond’ water heater miracle

In 1998, A. O. Smith received a letter from Mrs. Price of Virginia, who was amazed that the water heater her father installed half a century ago was still running. The decommissioned water heater is now placed in the A. O. Smith museum, a testament to the high durability of the Blue Diamond tank.

What Singaporeans are saying:

I bought the ‘Blue Diamond’ Technology to replace my 5-year old storage tank that had its heating element corroded due to the build-up of scale. Even though the price is slightly higher, I genuinely and truly believe it’s money worth spending.

An Interior Designer myself, I have been recommending water heaters from AOS Bath to my clients and all of those who got them had no complaints. Definitely one of the best-looking and well-built ones I’ve come across.

After experiencing multiple cold showers with our previous water heater, we decided that it’ll be a priority for us to invest in a good water heater for our new home. After extensive research, we decided on A.O Smith as it was a reputable brand from the US with a long history in manufacturing water heaters. We have no regrets at all as we believe in quality of the product.
