The problem of cold batteries is reading to interest in the period of junior frost. This applies to the apartment with central heating. There may be three problems here:
- Insufficient pressure in the system, as a result, 7 - 9 floors cold.
- Air in the system, as a result of partially cold batteries.
- Insufficient temperature of the coolant (water in the system).
Here are some tips, how to make batteries warmer, so as not to freeze in the student winter time.
Cold batteries due to insufficient pressure
There are two reasons for insufficient pressure in the system, these are leaks and formation of scale in the middle of the system.
The leaks appear when the heating system is trial started when the pipes are formed in the pipes, and puddles appear in the weakest places. It is very good if these places are in the available places, much worse - if it is difficult to get to them or difficult to detect. When removing the rubbing and restoration of sealing, the pressure will be restored and heat will appear in the batteries.
If the leaks are not detected, it means that it is scale. It is necessary to remove it at the beginning of the heating season with a special washing fluid.
Cold batteries due to air traffic jams in radiators
The formation of air traffic jams in professional terminology sounds like "enjoy". So, make it possible for several reasons:
- When filling out the system after repair.
- When water is heated, gases can be released and one large bubble is formed, which does not allow the thermal agent to move.
- Due to outdated radiators, where the air traffic jam is formed after a certain time (8 - 21 hours).
To remove air, you need to use the crane of Maevsky and the key, when you turn up 45 degrees, the accumulated air comes out, and the radiator is filled with moving hot water.
The probability of the formation of air traffic jams is large in systems with a variety of knees.
Cold batteries due to low water temperature in them
The temperature in the batteries should be such that the apartment rooms are from 18 s (living room) to 25 s (bathroom), this is a comfortable temperature for accommodation. Provides such a temperature of hot water in radiators, its temperature should be from 85 to 90 s (depending on the floor). If the temperature in the residential rooms is less, you need to contact the HSE, in writing to describe the problem and wait the same, written response. The problem of insufficient temperature of the coolant in the system does not solve independently, it is necessary to either inhibit the problem, or the ZHECs solved the problem, the task of tenants to report a situation.
Now you know the possible reasons for cold batteries in the room, so it will be easier for you to eliminate them.
