Coating of the heating element

The outer covering of the heater is a significant factor in determining the characteristics of the kettle because it is in direct contact with the heated water. Therefore, the material used for this coating is an essential consideration in the kettle's properties.

— Stainless steel. "Stainless steel" is the most commonly used coating for kettles as it is affordable and provides good resistance to scale buildup. However, compared to more advanced materials, it may not offer the highest level of scale resistance.

— Aluminium. Another common material, slightly more expensive and resistant to scale than stainless steel, but in general not having significant differences.

— Ceramic. Ceramic coating is known for its exceptional resistance to both scale and corrosion. Although it cannot provide a complete guarantee against scale buildup, it does tend to form plaque at a much slower rate than on surfaces made of steel or aluminium. Additionally, many of these heaters can be cleaned with more aggressive descaling products that would not be suitable for metal coatings. However, due to their high cost, ceramic coatings are typically only used in premium kettles.

— Silver. Silver is another premium material that has good resistance to both scale and corrosion. In addition, it also possesses some antibacterial properties, making it a suitable choice for those who use the kettle to store cooled boiled water. However, the cost of silver pla...ting is quite high.
