Electric tubualr heater has been widely used in water heating, most of them are made of stainless steel, but some customers use copper tube. But as the water tank electric heating, which pipe material is better? copper or stainless steel?
Let's discuss and analyze the both pipe material from the following aspects
1、 Thermal conductivity
The thermal conductivity of copper material electric tubular heater is better than that of stainless steel electric tubular heater, and the heat transfer of copper material of the electric tubular heater has a faster thermal conductivity than the same size of stainless steel material.
2、 Production cost
Because copper is a rare metal compared with stainless steel, the cost of copper material electric tubular heater with the same size parameters is higher than that of stainless steel electric tubular heater.
3、 Installation
Because of the high cost of copper material, the water tank on the market is basically made of stainless steel. Therefore, when welding the external connection of the mother tooth ring and the mother flange, the stainless steel water tank and copper material belong to dissimilar metal welding, which must be brazed. Adding silver electrode, this kind of electrode is more expensive, which increases the cost.
Compared with copper electric heating pipe, stainless steel electric heating pipe and stainless steel water tank are easy to weld and firm.
4、 Impact on water quality
Copper electric heating pipe will produce copper green and pollute water source for a long time. Stainless steel electric heating pipe will not produce copper green.
Therefore the advantage of copper material electric tubular heateris faster heat conduction, but stainless steel electric heating pipe has more advantages in production cost, installation and impact on water quality. Therefore, whether the water tank electric heating pipe is copper or stainless steel depends on which aspect of advantages you attach more importance to. This is depends on the requirements from the customers' appliacation requirements. For Jaye industry, we can meet our cutomers' needs on both materials.
