An effective way to solve the problem that the radiator is not hot
If the entire set of radiators is not hot or hot, it may be that the lock valve at the inlet of the radiator, the temperature control valve and the return valve at the outlet are closed, making the hot water unable to move normally.
No heat treatment method:
Turn the lock valve and temperature control valve of the radiator in the water return position counterclockwise to open.
What should I do if the pipe or valve is blocked by debris and the radiator is not hot?
If the heating effect of your radiator is worse than every year, or lower than the previous stage, or some radiators are not hot, especially those users who do not have filters installed on the outdoor mains. At this time, the reason is probably that the radiator or valve is blocked by debris in the system.
Treatment method: find real estate to thoroughly clean the piping, heating equipment and valves of the entire heating system.
Third, what should I do if there is no timely exhaust during the initial heating, and the heating radiator is not hot?
In the early stage of heating operation or when the heating is restarted, the heating pipes and radiators are prone to air blockage, which makes the heating radiator flow poor, and the heating radiator is not hot? How to do it
The processing method is as follows:
1. Automatic exhaust valve exhaust of the entire heating system: The exhaust valve can automatically exhaust, and it is generally located at the highest point of the entire heating system, that is, the top layer. When the automatic exhaust valve is exhausting, do not cover the valve with plastic cloth or other objects, so as not to affect the exhaust effect, and the exhaust pipe should be led to the outdoors.
2. Manual exhaust valve for each group of radiators: You can use the manual exhaust valve on the top of each group of radiators to stop the exhaust: quietly screw in the manual exhaust valve until water flows out steadily, and then tighten the exhaust valve. When exhausting, you need to use a container such as a washbasin to collect water to avoid wetting the air.
What should I do if the inlet and return water pipes are installed reversely and the radiator is not hot?
The installation method of the radiator is generally top in and bottom out, that is, the hotter water inlet pipe is on the top and the colder water return pipe is on the bottom. If the device goes in and out, the bottom of the radiator will be hotter than the top. Of course, the radiator will not be very hot due to poor circulation of hot water.
Solution: Find the equipment company of the radiator and reinstall the top-in and bottom-out.
The pressure of the heating system is low, so what should I do if the heating is not hot?
If there is some heating in the room, some radiators are not hot, or they are not hot at all, or the effect is not good, it may be that the pressure of the heating system is low. Under normal circumstances, it is generally necessary to ensure that the heating pressure of the home is not less than 0.3Mp. During the heating test or when the heating is just started, the heating company generally runs at low pressure to avoid excessive pressure in the system and leaking of pipes. If it is still not hot after one week of formal heating, and the entry pressure is still lower than 0.3Mp, go to the heating company or the property company to deal with it.
In addition, the small pressure difference of the return water at the home will also cause the radiator to not be hot. The direct manifestation is that the radiator is not hot, or some are hot, some are not, or the top of the radiator is hot but the bottom is not. Turn off other radiators and only turn on a set of radiators that are not hot. If it is hot at this time, it means that the cargo pressure difference under pressure is small. The inlet and return water pressure difference is small, the water flow is slow or if you are happy, you will not be active. The difference between the inlet water pressure and the return water pressure of ordinary households is not less than 0.05Mp.
Disposal method: find a heating company to adjust the household pressure difference.
