Tank comparison

 COMPARISION BETWEEN SS TANK AND ENAMEL TANK

 
ENAMEL TANK
Porcelain Enamel Tank - is a trusted & proven technology for inner tank of water heaters. Used widely across the world, it is ideal for long life & trouble free performance in all kinds of water. More than 95% of water heaters produced worldwide are with enamel tanks. Corrosion protection is very good due to fusion of glass layer to metal.

 
SS TANK
Stainless Steel Tank - this is an outdated technology that manufacturers are moving out of now. Corrosion protection is very poor, particularly in hard water and due to poor welding quality.
 
SL Description Enamel Tank SS Tank
1 Protection Coating Porcelain Enamel -
2 Coating Type Inorganic None
3 Coating Thickness 250 - 400 microns None
4 Coating Adhesion Fused with metal None
5 Baking Temperature 850 deg C -
6 Life of the Coating Long life -
7 Usage Widely used Internationally Limited. In very few countries
8 Material Mild Steel Stainless Steel

12 Hard water Suitability Good Poor
13 Corrosion Protection V.Good Poor-Average
14 Hot Water resistant V.Good V.Good
15 Approved Quality Standards BIS, IEC, DIN & UL BIS
 
HARD WATRT
As so common problem for millions of households across the country.Hard water means excessive dissolved minerals, specifically calcium and magnesium in tap water various in different countries.
Hard water is a negative impact because of much limescale it brings, Thus, in water heaters the heated hard water forms a scale of limescale deposits on the tank surface and reduces the heat conductivity of heaters sometimes even leading to its breakdown. and this contributes to inefficiency and costly electricity bill . Limescale has been known to increase energy bills by up to 25%.
