  • Where can the water heater be installed?

    Your water heater can be installed in your home, or at the place of installation requested by you. Whether you buy water heater for your home or for commercial use, our expert technicians will install it for you.

  • Will it be installed in a warm or a cold climate?

    Given that in colder climates the ambient temperatures are lower, the heating element will take longer to heat water to the desired temperature. In such colder climates, it helps to have a larger capacity water heater to ensure a steady supply of hot water.

  • What is the suggested family size for using a certain capacity of water heater

    In large-sized families, several members tend to use the bathroom in a short span. It helps to have a larger water heater capacity, to ensure a steady supply of hot water for everyone.
    We have given you a rough idea above of the capacities required for average use. Do remember that capacities vary according to family size, water usage patterns and weather conditions. In colder climates, for instance, hot water consumption is higher.

  • How to choose between a vertical and a horizontal orientation

    Besides choosing the capacity of the water heater, you will also need to choose between horizontal and vertical models.

    1. Smaller water heaters [6 to 25 litres] are usually vertical models, many of these usher in a new elegance.
    2. Large water heaters [35 litres and above] are available in both vertical and horizontal models. These are generally cylindrical in shape with few embellishments and can be installed in lofts as well.

    Depending on the space available in the installation area, you can choose between horizontal and vertical models. A. O. Smith has a range of really attractive vertical and horizontal models, in capacities from 1 to 100 litres.

  • How effective is the inner container[tank] of A.O.Smith water heaters?

    The inner container tanks of A. O. Smith Water Heaters are constructed using a heavy gauge mild steel and Blue Diamond® technology. A. O. Smith offers 5 to 7 years warranty on the inner container tank.

  • How does the Quality of Water Affects the Inner Container [Tank]

    The quality of water has a major effect on your water heater. Hard water contains high levels of mineral salts like calcium and magnesium. The minerals present in the hard water can cause scaling. Scaling leaves behind a white, chalky kind of salt deposit in the inner container and on the heating element.
    The problem is particularly acute in areas where the water is very hard [large dissolved salt content]. Over a period of time, this residue keeps building up and starts interfering with the efficiency of the water heater.
    To avoid major functionality issues of geyser, it is recommended to run some water for the removal of the residue.

  • How good is the heating element of A.O.Smith Water Heaters?

    The elements in A. O. Smith Water Heaters are glass coated, which is the most effective in the industry for prevention of scaling. This also extends the life of the water heater.

    A. O. Smith has a range of water heaters in different capacities with dual heating elements. This helps heat water faster and in case one of the units fails, then the other acts as a backup ensuring that the water is heated. It is recommended in all areas that have hard water.

    A. O. Smith offers a 2-year warranty that can be extended to 4 years if registered within the first 2 months of purchase. Once again, this is the longest warranty offers in the industry.

  • How does the quality of insulation affect the water heater?

    A. O. Smith water heaters use high density, high quality extruded PUF. This provides a superior insulation blanket which retains the heat generated by the heating element in the water stored in the inner container tank. It saves more energy making your water heater energy efficient.
    A. O. Smith Water Heaters also have a safety valve that helps to relieve and discharge water in case the water pressure or temperature overshoots the pre-set limits. The safety valve opens up and discharges water through the drainage.

  • What are the safety features in A.O.Smith Water Heaters?

    A. O. Smith provides protection against very high temperatures and pressure.
    While accidents with water heaters are rare, most of the accidents that happen are largely caused by absence or failure of safety features.
    A. O. Smith Water Heaters have a thermal cutout which rapidly cuts off the live and zero line simultaneously, effectively cutting off the electricity supply in case the water temperature exceeds the highest pre-set temperature and ensuring safety.
    A. O. Smith geysers also have a safety valve that helps to relieve and discharge water in case the water pressure or temperature overshoots the pre-set limits. The safety valve opens and discharges water through the drainage.

  • Does the water heater come with a remote control and digital display?
