How to avoid dirt and rust problems in electric wall-mounted boilers

Electric wall-mounted boilers can develop dirt and rust around their exterior during operation. How can we prevent these problems? Let's explore the potential issues.

After a period of operation, the boiling and evaporation of water in the boiler creates chemical reactions and continuous concentration of impurities in the water. Some boilers with poor water quality or pre-treatment processes create conditions for chemical reactions and continuous concentration of impurities in the water. When the tank of water reaches saturation, solid matter precipitates and settles on the heated surface, a phenomenon commonly known as scale. This long-term accumulation causes the interior of the electric wall-mounted boiler to become dirty. After extended operation, electric wall-mounted boilers inevitably experience scaling and rust. The primary cause of these problems is the hardness of the water. Continuous evaporation and high-temperature, high-pressure concentration trigger a series of physical and chemical reactions within the boiler, forming a hard, dense oxide scale on the heated surface.

Common Material Selection for Corrosion-Resistant Centrifugal Pumps for Electric Wall-Mounted Boilers: The corrosion resistance of most corrosion-resistant pumps depends primarily on the material of their flow-through components. For corrosion-resistant pumps, the material of the flow-through components must be selected based on the specific medium being conveyed. This material is only suitable for use with certain corrosive media, but is essentially resistant to all acids and alkalis, earning it the nickname "the king of plastics." In addition to the materials listed above, ceramics, enamel, and glass are also used in certain applications to manufacture corrosion-resistant pump flow components. Scaling on the inner walls of electric wall-mounted boilers reduces thermal efficiency and is a major cause of energy waste. It is recommended to treat boiler water by magnetizing or softening it, which not only saves energy but also extends the boiler's lifespan. Atmospheric pressure boilers, also known as electric wall-mounted boilers, are boilers with the top open to the atmosphere and are not subject to the static pressure of the water column from the heating system. They are equivalent to open hot water tanks. Circulating water pumps can only be installed on the hot water supply main and must be equipped with a check valve and flow control valve. Therefore, circulating water pumps do not circulate water, but rather pressurize it. They are essentially booster pumps, much like cold water booster pumps in water supply projects. They pump water from the reservoir to the water tower, and then by gravity to the user.
