5 key points of heating system maintenance

  • 2022-01-03 15:47

1, good water maintenance
Whether it is a central heating system or an independent heating system for a home wall-hung boiler, whether it is a steel radiator, a cast iron radiator or a copper-aluminum composite radiator, it can be fully maintained with water. Full water maintenance can isolate oxygen, reduce the oxygen content in the water, prevent oxygen corrosion, and extend the service life of the radiator.
2. After the heating is stopped, check for water leaks
After the heating is stopped, the temperature of the heating equipment will drop. Due to thermal expansion and contraction, water leakage may occur at the pipe connections and valves. Therefore, it is recommended to carefully check whether there is water leakage at the interface after stopping the heating. If there is a slight water leakage, you can tie a towel. The towel will suck the water away and will not harm the floor and wall in the short term. If the water leak is serious, you should contact a professional for repair as soon as possible.

3. Replace the old radiator in time
For radiators that are not hot during the heating season, water seepage at welds or joints, serious surface deformation, and old styles, the radiator should be inspected and repaired by a professional radiator installer, if necessary, as soon as possible Replace with a new set of radiators. It is recommended to replace the radiator that is not used for an extended period of time and the radiator that is not energy-saving and environmentally friendly in time during the heating period. When replacing, choose a radiator with high safety, energy saving, environmental protection and long service life.
Radiator cleaning method:
After a heating season, the cracks and surfaces of the radiator will accumulate dust or oil, and become unhygienic, so it is necessary to clean and clean the radiator. When cleaning the surface of the radiator, please use a soft towel or brush. You can use daily detergent, weak alkaline soapy water, etc. to help clean it. Do not use any kind of organic solution.
4, floor heating equipment should be cleaned in time
floor heating has become the choice of many families because of its convenience and beauty. After the heating is stopped, the floor heating equipment needs to be overhauled. The water in the floor heating pipe circulates for a long time, and the water contains a lot of microorganisms. Under certain conditions, a large amount of biological mud, bacteria and scale will be produced on the inner wall of the pipe. There is a possibility of blockage. Therefore, it is good to perform a thorough cleaning of the floor heating pipeline after the heating is stopped, and thoroughly remove the dirt, impurities and bacteria formed in the pipeline in time to prevent the sediment formed in the pipeline from causing pipeline embolism.
5. Carry out a thorough maintenance and inspection of the wall-hung boiler
Internal cleaning and descaling can effectively reduce the load of main components such as water pumps and heat exchangers, reduce the wear of operating parts, reduce the failure rate, and make the boiler run more smoothly. If the boiler is cleaned and maintained every 1 to 2 years, it can be Extend the service life of the equipment by 3 to 5 years.
I would like to remind users here that once the heating season is over, the wall-hung boiler only undertakes the daily household central hot water function. When using it for bathing, you should pay attention to the following two points:
1. The hot water faucet should not be opened to the full. Turn on the hot water faucet until hot water flows out. There is a delay of about 10s. At this time, the pipeline between the boiler and the faucet is full of cold water. If it is turned on, water will be wasted. Therefore, when using hot water, you should turn on a small water flow first, wait for the boiler to start to the ignition delay, and then adjust the water flow according to your needs, especially for large apartments where the bathroom is far away from the boiler.
2. Minimize the number of taps on and off during the bath. Since the boiler must be started every time the hot water faucet is turned on and off, there will be a delay of about 10s, and when the wall-hung boiler is boiling water, it burns with a large fire before reaching the set temperature, which also increases the gas consumption.
During the period when heating is stopped, we must not neglect the maintenance of heating equipment. On the contrary, this period is precisely the best cleaning and maintenance time, which not only prolongs the service life of the equipment, but also ensures its normal operation in the next heating season.
