Many people are now facing the problem of uneven heating of batteries. And the colder it is outside, the more acute this issue will be, because the comfortable temperature in the apartment and house will depend on how the radiators heat up. Moreover, this does not depend in any way on the material from which the batteries are made. Is it possible to somehow combat this? It is possible and necessary. Let’s discuss the causes of such problems and how to fix them.
Air got in
This is the most common reason for uneven heating of radiators. An airlock has entered the heating system, and it is this that prevents the normal movement of the coolant.
Modern radiators have a so-called Mayevsky tap. This is a valve for bleeding off excess air. A couple of minutes – and the problem is solved.
Foreign body in the system
The cause of uneven heating of the radiator may be sediment or a foreign body that has clogged the system. Scale inside old batteries under pressure can separate and clog narrow coolant passages.
In the end, debris can enter the system from the outside if the system is not centralized, but receives recharge from open hydraulic tanks.
Dirt can accumulate in any place that is difficult for coolant to pass through, and usually, these are radiators. There are two working ways to clean batteries from debris. The first is a simple mechanical cleaning, in which the battery is disconnected, the water is drained from it, and the water is tapped with a rubber hammer to separate the debris. After this procedure, the radiator is washed with good water pressure and put in place.
The second option is to use cleaning compounds. This can be any remedy for blockages. It is filled with hot water and left in the disconnected battery for half an hour, after which it is washed.
Failure in the locking system
Modern batteries are equipped with ball valves with thermal heads to regulate heating. They can also cause uneven heating.
Low system pressure
The difference in temperature between the top and bottom of the radiator may be a result of insufficient pressure in the system. Old-type apartment buildings often suffer from this. The batteries there are cast iron, with passages half-overgrown with scale.
A decrease in pressure can occur if your neighbors have unauthorizedly increased the number of their batteries or adjusted them so that the equipment simply does not cope with its task.
You won’t be able to solve this problem alone. You need to contact the management company and convey to them not only your problems but also assumptions about the reasons. There is no time for friendship with neighbors – your shirt, as they say, is closer to the body.
