1. Cleaning the copper tube of the heat exchanger: In the long-term use process, some impurities such as oxides and calcium salts may accumulate in the wall-hung boiler, which will affect the circulation and conduction of hot water and even short-circuit the pipeline. Therefore, it is necessary to clean the copper tube of the heat exchanger regularly. Cleaning method: first stop the water supply of the wall-hung boiler, open the wall-hung boiler panel, then remove the heat exchanger or install an external circulating pump, circulate water repeatedly, and thoroughly clean the inside of the pipeline.
2. Replace the heating plate: The heating plate of the wall-hung boiler is an important part of the hot water heat exchanger, which is responsible for converting electricity, gas and other energy into heat energy. If the heater is damaged, dusty or aging, it should be replaced in time. Replacement method: First, you should know the model, specification and location of the heater of the wall-hung boiler, then remove the damaged heater according to the instructions, compare it with the new heater, determine the installation position and direction of the heater, and then reinstall the new heater.
3. Replace the heat exchanger: The heat exchanger is one of the core components of the wall-hung boiler and the key component of the hot water exchanger, which mainly undertakes the task of converting the heat energy in the gas into hot water. If the heat exchanger fails, it needs to be replaced in time. Replacement method: first turn off the gas and water, then remove the heat exchanger and replace it after cleaning the internal impurities. Before replacement, you need to prepare the corresponding heat exchanger according to the model, and fill in the corresponding technical data and maintenance company warranty card before replacement.
4. Replace valves and accessories: The valves and accessories of wall-hung boilers also need to be inspected and replaced regularly. If there is leakage and aging, it should be replaced in time. Replacement method: first close the valve, unscrew the fastening screw of the valve, then remove the old valve or accessory, install a new valve or accessory, and seal the valve core.
In a word, it is very necessary to maintain the heat exchanger of household wall-hung boiler, which can not only make household heating more comfortable, safe and secure, but also have better economic benefits. When removing and replacing parts, you need to be careful. If you are not clear about the specific operation methods and technical requirements, please consult a professional maintenance master.
