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.
Smaller water heaters [6 to 25 litres] are usually vertical models, many of these usher in a new elegance. 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.

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.

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.

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.
