Blue Diamond Glass Coating to Avert Corrosion

When talking about the geyser, the inner tank is the essential section. Now, the water quality directly affects the water heater. There is a hard water problem in many regions of India. 

This hard water contains high levels of magnesium and calcium, which can lead to scaling. After some time, this residual layer accumulates and inhibits the heating performance of the geyser. Therefore, measuring the inner tank will make it more susceptible to corrosive elements to cause a water leak.

AO Smith, backed by a decade of experience, has introduced the Blue Diamond Glass Coatings to counter this complex issue. It produces better corrosion resistance when compared to ordinary glass-lined geysers. 

Moreover, modern geysers heating elements have a glass coating to combat corrosion. As the AO Smith has the breakthrough technology, it significantly improves the life of the inner tank. That’s why AO Smith offers a 7-year warranty on its elite storage heaters with this technology.

Ideal for Tall Buildings

Most geysers have copper or stainless steel tank construction. These are vulnerable to high water pressure so you can find these tanks in high-rise buildings or apartments. 

However, the AO Smith’s inner tank is heavy-duty mild steel reinforced by patented Blue Diamond technology. As a result, it can withstand high-pressure conditions. Premium storage AO Smith water heaters can withstand 8 bar pressure.

The water heater is equipped with a digital thermostat. It regularly checks the temperature of the water, and it automatically shuts off the power supply when the temperature exceeds the allowable level. It ensures safety and helps reduce electricity bills and prevents electricity wastage. 

Energy-efficient PUF Injection Technology

Advanced PUF needle ensures high density and uniform foam distribution. Zero gaps between insulation and tank guaranteeing to ensure maximum energy efficiency and power saving.

Efficient Inlet Water Diffuser

The next notable feature here is the efficient inlet water diffuser. It breaks the incoming water jet into small streams and converts the water flow vertically to horizontally.

The major disadvantage that we have found in this geyser is the lack of stunningly designed geysers. 

Temperature Control Knob
