Enamel water tank
|
VS
|
Stainless steel water tank
|
The inner tank use professional enamel material, CO₂ welding process and special adhesion. It will not leak easily
|
Weilding
|
Direct contact with water will be easy to leak.
|
After 480 hours of salt resistance test, the tank has a good anti-corrosion effect
|
Anti-corrosion
|
After acid resistance test,prone to corrosion and leak
|
The internal water tank is easy to clean, and there is almost no water scale.
|
water scale
|
easy to have water scale and difficult to clean, which will affect the heat transfer effect.
|
It's still intact after reaching 70°C
|
High temperature resistance
|
High temperature will accelerate the corrosion of the tank weld and reduce the service life
|
Usually more than 15 years
|
Service life
|
It will happen corrosion and leakage after 2 years
