       ii. Thermoplastic (Also some companies indicate as a polymer tank)

      iii. Stainless steel

Copper is a very good conductor of heat, but the problem is that it results in the loss of heat which we do not need in water heaters. Moreover, it is corrosive. Thermoplastic is non-corrosive, but the insulation used in it is not as good as stainless steel. A Copper or Thermoplastic tank will need better insulation as compared to stainless steel to keep heat from going out of the tank. Also, the Life of stainless steel containers is better than other two containers.
