The radiator is abnormal. Do you know the reason? How to deal with the noise of radiator? Let's take a look at it with the golden flagship flag brother.
when the heating system is started for the first time, there will be residual air in the pipeline or in the heating. If there is too much residual air, the heating will not be hot. Therefore, timely exhaust can make your home life warmer and happier.
The specific situation is as follows:
When discharging the air in the radiator, mainly observe the water outlet, and see if there is any hissing noise from the air-water mixture at the exhaust port. If the water flow is gentle, it means that there is no air in the radiator air.
Venting the heater in the right way will improve the use effect of the heater, which is more conducive to the normal operation of the heater. Some stubborn systems have accumulated gas and need to be exhausted many times to achieve a complete use effect.
Some users who have used heating for a while have reported: "In the dead of night, the radiator will make abnormal noises and there will be a rushing sound of running water." .
The main reasons for this abnormal sound are:
There is gas in pipes and radiators, and the noise caused by insufficient water supply.
In this case, you can open the vent valve of the radiator and hear the sound of flapping until the water flow is smooth and you don't spray water intermittently.
it is caused by uneven water flow in the radiator or sundries being washed away.
It is suggested that the radiator should be removed, and the residual sediment in the heating pipeline and radiator should be washed with an air pump.
when the water intake and water return of the radiator are not balanced, it will also produce sound.
At this time, the water supply and return valves of radiator gas can be properly adjusted to reduce the flow and make it balanced;
if the radiator makes abnormal noise instead of underwater sound, it is more like the sound of metal knocking, it is because it expands with heat and contracts with cold. When the radiator rubs against the metal bracket installed on the wall due to thermal expansion during heating, it produces sound.
It is suggested that users can solve the problem by stuffing paper with moderate thickness into the gap between the radiator and the metal bracket.

how long is the service life of radiators?
The service life of steel radiators in the market is generally about 5-1 years, and the service life of copper-aluminum composite radiators is 2-3 years. Because of the different raw materials used in radiators, the service life of radiators is also very different. How long is the service life of radiators? Different materials and brands are different. However, the golden flagship flag brother can be sure to choose radiators of well-known brands. The life of radiators is at least known, and it is longer than that of ordinary radiators.
The service life of radiators is closely related to the raw materials used, and also to the water quality of heating. Radiators are more susceptible to corrosion in complex water quality. Of course, it is also closely related to collective heating or household heating. If it is household heating, it can be used for about ten years.
how to improve the service life of radiators?
1. The steel radiator is suitable for the central heating system with full water maintenance. When purchasing, you should first choose the steel radiator with internal anti-corrosion technology, otherwise it will be easily corroded and lead to water leakage; Copper-aluminum composite radiator can be used in pressureless boilers and central heating systems. However, if the hot water in residential areas is in a high temperature state for a long time, exceeding 8℃, it will easily lead to the disconnection between copper and aluminum and lose the heat dissipation effect.
2. Wet things should not be put on the heater at ordinary times, which will further corrode the radiator and shorten the service life. Don't beat or shake the radiator or use the radiator as a support to put things up.
3. Do not drain water from the system at will. If there is a lack of hot water in the pipeline, it is necessary to supplement cold water to keep the pressure of the pipe network system at a certain level. The more hot water is released, the water temperature in the pipe network will drop rapidly, resulting in a decrease in indoor temperature.
what is the reason for the abnormal sound of the radiator? How to deal with the noise of the radiator, the way is here!
Friends who use steel heating should pay attention to closing the valve in time when the heating is stopped, so that the heating is filled with water, which can prolong the service life of the radiator.
4. The heating position should not be changed arbitrarily. The installation of radiators is arranged in a position that is conducive to indoor heating, which can ensure the air convection and the relative average indoor temperature. Once the position is changed, the indoor temperature will be unbalanced.
on the other hand, once the pipes and radiators are moved, it is very easy to leak and cause unnecessary losses.
It is worth mentioning that the radiator made of steel, copper and aluminum, or other materials is maintained with water.
