Consumes Very Little Power: You will never have to worry about high utility bills if you choose this model. For starters, it is quite efficient and can produce hot water in a short period of time while utilising very little power. Because it has a modest capacity, its power consumption will be even lower. As a result, it’s an excellent choice as a long-term investment, especially if you live alone or have a small family.

Compact Yet Pleasing Design: This heater can be installed on the wall, so your bathroom won’t have to accommodate much space. Its white finish and blue diamond glass-lined tank offer it a contemporary appearance that will go well with any bathroom’s design.

Comes With Enhanced Durability: The AO Smith 15-Litre 2000-Watt Vertical Water Heater is composed of high-quality materials. The inner tank, for instance, is lined with glass to prevent corrosion. This increases its lifespan and makes it much more durable than most models on the market.

Notes About This Model

Display Could Be A Little More Visible: While the body of this geyser is mainly well-designed, the little LED display could’ve been designed better. It’s sunken in rather than level with the rest of the geyser’s surface. When installed at a height, the lower section of the led panel obscures the view, making it difficult to see the set temperature.
