The reliability and the heating speed of a water geyser are usually not given much importance before the buyer is faced with an emergency situation where it is impossible to use the appliance at all due to breakdowns. So, in addition to the impressive features list, the buyer should be more interested in the reliability and the heating speed of a geyser. Being equipped with 2KW heating element and having 5-star BEE rating, we examined the AO Smith VAS PLUS 15 Litre model in the course of several weeks of daily tests, measuring the heating speed of a full tank of cold water, checking its hot water consistency in the process of back-to-back usage and seeing whether the energy rating influences the electricity bill.
Why Do You Need a Good Water Heater in Your Bathroom?
Finding a balance between energy efficiency and effectiveness is what makes water heaters complicated. The AO Smith VAS PLUS 15L water heater comes with a promising offer – high pressure compatibility and durability. If you are living in an apartment or hard water areas, this device is made just for you.
The Performance Analysis
At the center of this appliance stands the Blue Diamond glass-lined tank. No, it's not just a name, as it significantly improves durability by protecting the appliance from corrosion, which causes most water heaters to malfunction after several years of operation. Combined with the 5-star BEE rating, it provides great heating capabilities while maintaining low electricity expenses.

What makes it worth buying is not only heating speed but also the comfort of 7-year tank warranty, which is better compared to many other budget alternatives in this price range.
Benefits of This Water Heater for Your Home

When to Consider Buying This?
This is a perfect solution for a small or medium-size family living in an apartment building with changing water pressure. For those who care about warranties provided by a brand and quality construction, this product should be considered as a smart choice.
When Not to Consider Buying This?
In case you are a big family and your household needs continuous supply of water to use it for several showers in a row, the capacity of 15 liters would be insufficient, so maybe you should look into 25 liters device. Another thing to consider is that you would need to buy separate hose pipes as they come without this product.
