Active maintenance tips 140 years of AO Smith once again upgrade the "fast forward button" electric water heater

As a flagship product of the AO Smith family, the electric water heater with the "fast forward button" has undergone another significant upgrade. This time, it introduces a new active maintenance reminder function, along with a much faster heating speed and an impressive increase in hot water capacity—up to five times more than before.

This year marks the 140th anniversary of AO Smith, one of the most respected names in the water heating industry. Since entering the Chinese market, the American brand has consistently focused on R&D, innovation, and delivering high-quality products. It continuously adapts its offerings to meet the evolving needs of consumers, ensuring that technology serves real-life convenience.

Water Heaters Now Have "Self-Maintenance" Capabilities

Electric water heaters require regular maintenance, even in areas with good water quality. Over time, the anode rod inside the tank can wear down, reducing its effectiveness. "If not maintained in time, impurities in the water can start eroding the inner liner," said Ding Wei, Senior Vice President of AO Smith Group and President of the Chinese subsidiary. "To address this issue, the AO Smith Global R&D Center has innovated and upgraded the 'fast forward key' feature."

The IMM Liner Intelligent Maintenance Prompt System (Invention Patent: ZL201210318688.9) developed by AO Smith automatically adjusts protection strength based on local water quality. It releases protective ions to neutralize aggressive elements in the water, effectively protecting the inner tank. Additionally, the system regularly monitors the condition of the anode rod. With the "maintenance self-test" function, users can instantly check the tank’s status. When maintenance is needed, simply call for service, and a professional will come to your door for a full inspection and repair.

In addition, the new model now includes an "inner tank self-cleaning" feature, ensuring cleaner and safer hot water for bathing.

"Fast-Forward Button" Upgrade Boosts Hot Water Capacity Fivefold

One of the core challenges with electric water heaters is heating efficiency. According to reports, AO Smith's Global R&D Center spent three years developing a solution to this problem, eventually launching the "fast forward key" electric water heater. On the occasion of its 140th anniversary, the company has made another breakthrough, increasing the heating speed by five times and expanding the hot water capacity fivefold. The output rate of hot water now far exceeds national energy efficiency standards.

"The name 'fast forward button' reflects its unique rapid thermal variable capacity and MAX capacity expansion system," explained the development team. The patented MAX rapid heating/heat storage 2-in-1 technology (Patent No.: ZL200820185859.4) ensures fast heating, with the speed of heating half a tank of water being five times faster than the second-generation model. The "MAX compatibilization" system allows for super-fast heating, using a unique structure to achieve a relay heating effect, providing up to five times the capacity of the water heater continuously.

140 Years of Commitment to R&D Has Made AO Smith a Water Heating Expert

With the latest upgrades, including "active maintenance tips" and "inner tank self-cleaning," AO Smith continues to enhance the user experience, proving its strong technical foundation. The company has established three global R&D centers, aiming to build the most professional product base. In China alone, there are nearly 200 R&D personnel dedicated to innovation and improvement.

Through continuous technological innovation, AO Smith remains committed to offering users a better water life. This focus has led to the brand’s current industry leadership and a reputation for excellence in water heating technology.
