How to Clean Scale from Heating Tubes
 
There are several methods to remove scale from heating tubes, and you can choose the most suitable one based on your specific situation:
 
1. Vinegar or Citric Acid Solution: Mix white vinegar or citric acid with water in a specific ratio, heat the solution, and soak the heating tube to soften and remove the scale.
   
2. Baking Soda Solution: Boil water with baking soda and use the solution to soak the heating tube to eliminate scale.
 
3. Potato or Eggshell Method: Boil potatoes or eggshells in the heating tube to help break down and remove scale.
 
4. Alkaline Cleaners: Use alkaline cleaning agents, such as a soda ash solution, to soak the heating tube and dissolve the scale.
 
5. Specialized Cleaners: Use cleaning products specifically designed for heating tubes, following the instructions provided.
 
6. Mechanical Cleaning: Gently scrub the surface of the heating tube with a metal brush or sanding tool to remove scale.
 
7. Hot Water Soaking: Soak the heating tube in hot water and then rinse it thoroughly with clean water.
 
In addition to these methods, regular maintenance and inspection of heating tubes are effective ways to prevent scale buildup. Before using any cleaning method, ensure safety measures are in place, such as wearing gloves and a mask if necessary. For severe scale buildup, professional cleaning may be required.

 
How Often Should Heating Tubes Be Cleaned?
 
Due to long-term use and the impact of water quality, heating tubes are prone to scale buildup, which can reduce efficiency and significantly shorten their lifespan. The frequency of cleaning should be determined by the operating conditions of the heater and the water quality. Generally, it is recommended to clean the heating tubes every 2-3 months, with a deep cleaning every three years. Even water heaters labeled as "maintenance-free" should be cleaned regularly. When reinstalling the heating tube, ensure proper connections and tighten the screws on the flange to prevent leaks.
