When using radiators in winter, you need to pay attention to many details, if you find that the radiators at home are hot and cold, then you need to investigate the cause in time and deal with it according to the specific reason.
1. There is too much gas in the radiator: the pipeline is blocked, resulting in the radiator not being hot. At this time, the exhaust valve in the system can be opened to deflate until the gas is drained and the water flows out.
2. Pipeline access error: the thermal circulation line is abnormal. It is necessary to understand the thermal circulation system and piping of the whole building, and carefully inspect it to correct the wrong piping.
3. Blockage of heating system pipes: resulting in the radiator not being hot or partially not hot. It is necessary to identify the blockage, disconnect the pipe, remove the dirt from the pipe or replace the pipe section.
4. Unreasonable installation of pipeline slope: it leads to air locks inside the pipeline, which hinders the normal circulation of hot water. The slope of the pipeline needs to be adjusted to meet the slope and aspect requirements of the design.
5. Heating adjustment is not in place: indoor adjustment is required. For radiators connected in parallel, the valves of the first group of radiators entering the house can be opened smaller, and the subsequent radiator valves can be opened larger in turn.
6. Distinguish the connection methods and treat them separately: when the radiator is hot and cool, this indicates that there is sediment, and the loose joint cleaning plug needs to be opened; The radiator is cool and hot, there may be air blockage, and the radiator release valve needs to be opened to vent the air; The overall radiator in the indoor area of the series user is cool, and the upper and lower parts of the single group are not hot, or the upper and lower are cool, and the method of exhausting the gas from the single household, venting at the top floor, and discharging sewage at the bottom is adopted to solve the problem.
What are the common faults of radiators
1. Pipeline freezing and cracking: Due to the long-term absence at home in winter, the water in the pipeline was not released and was frozen and cracked. In this case, you can only find a professional installer to repair it.
2. Surface patent skin damage: due to carelessness, it is easy to damage the paint surface of the radiator. If possible, the paint should be repaired immediately, and nail polish can also be applied instead of spray paint.
3. Rusty valves: We will often encounter this situation, generally speaking, it can be wiped with rust remover, and if there is no rust remover at hand, you can use engine oil to lubricate it.
4. Radiator leakage: It should be selected according to the water leakage, and the valve must be closed immediately and replaced if the water leakage is serious; If it is not serious, you can use an elastic leather strip to wrap the leakage point tightly to stop the water.
5. Filter blockage: At the beginning, the heating was still hot, but after a few days, the heating was not hot, and this phenomenon was mainly caused by the blockage of the filter. At this time, it is necessary to close the entrance valve and disassemble the filter to rinse.
6. Radiator gas blockage: Some parts of the radiator are not hot, which may be due to the problem of radiator gas blockage. In this case, you can check whether the radiator has gas that cannot be discharged, and open the exhaust valve to expel the air inside the radiator.
7. The radiator is installed in reverse: a group of radiators is partially hot, or only the main pipe below is hot, this phenomenon may be that the radiator is installed in reverse. A reinstallation is required.
In short, in the heating process, users should check frequently, find problems in time and deal with them in time to ensure normal heating. If the problem cannot be solved, it is recommended to contact a professional heating repairer for inspection and repair.
