Cold and warm batteries are far from uncommon for many. This applies to skyscrapers and private homes. After all, warmth helps us find comfort and coziness in our homes. In the absence of proper heating, a cold appears in the room, which can contribute to various colds. So what is the cause of ice radiators? And what measures should be applied?
Dirty batteries
First, inspect the pipes along which the coolant goes to you. If they turn out to be hot, then it is necessary to conduct a conversation with the neighbors, to find out how things are going with their batteries, how warm the radiators are. If it turns out that their temperature is much higher than yours, then the problem should be sought only with you. Most likely they are contaminated with metal oxides and other dirt. It may interfere with the flow of hot media. Contamination of batteries can still be determined by touching them with your hand. If they are colder below and hotter above, then all impurities are deposited below the batteries themselves. If you try to heat the radiators themselves, the water warms up and moves, then the dirt will probably go away. But you can hardly clean it yourself. Experts are needed here. However, in winter, as a rule, they do not clean and flush batteries. Not only that, in our country there is not a single state-owned enterprise that would officially carry out such work, only some commercial firms carry out such work. But they are unlikely to be engaged in cleaning in the cold. In this case, we can only advise you to put new radiators.
There is air in the batteries
You have a new heating system and are convinced that they are not filled with dirt. Then in this case, probably, the air in the batteries interferes. You can get rid of it yourself. Each heating battery is equipped with a faucet, which can be opened and drained part of the water. After this manipulation should become hot. There are taps that are on the batteries themselves, and there are taps on the risers of heated pipes. You can open the crane on the battery or on the riser itself. Today they put cranes with a handle or Mayevsky cranes. According to the first situation, it is clear - you just need to turn the handle of the faucet, and the water will run, and air should also leave with it. If you have an automatic Mayevsky crane, then you will need a screwdriver. It will be necessary to unscrew the cap, push on the valve, only substitute the dishes in advance where the water will merge. When it merges, it will be necessary to close the air vent, and it will already be possible to be content with heat. In case you have a private house, it will be necessary to check each radiator separately. And if necessary, then open the tap and drain the water.
Mounting a heating system
Today, you can see several types of connection: lateral, lower and diagonal. Best is the last location. The connection will be incorrect if the hot water goes down the batteries. In this case, it will not warm up in full. In this situation, installing the extension of the fluid channel will help. An incorrect connection will also be considered a lateral one. Here, as a rule, the first 3-4 subsections warm up in the batteries. Others will remain cold, and only plumbers will be able to cope with this problem.
It happens that the last floors of residential buildings with hot batteries, and the lower floors with cold. Here, most likely, the point is the improper assembly of the entire heating system. It is impossible to cope with this problem on your own, here you will need the help of a heating engineer who is obliged to make calculations for the best heat supply system, and then in the summer deal with the installation of a new heating system.
Pay attention to the number of sections in the radiators. If you take each battery separately, the number of sections should not exceed 12 pieces. This applies to the gravitational system. The circulation system contains, as a rule, no more than 20-24 sections. If your battery has a larger number of sections, then they will not warm up sufficiently. Surely, the diameter of the pipes, which is responsible for the distribution of hot water, is still incorrectly selected in the design. If it is too small, then the pressure, accordingly, will be scanty and then, to warm up the batteries to the fullest extent, it may not be enough. It will save only the change of pipes with a large diameter.
Currently, in many dwellings and private houses, the owners put specialized and modern batteries with temperature controllers that work without a bypass device. But it is better to take care of its installation, otherwise you will have to live in a cold house.
In addition to all the methods described above, it is possible to increase the heat transfer from the batteries in the following ways, namely: constantly clean the batteries of dust, fasten the foil to the battery, which will be a reflector, paint it in a dark shade, since it gives off heat energy well. Take care of your heating system in advance!
