The technology and sequence of repair of heating radiators depends on the type and design of the battery itself. In addition, the cause of the breakdown is also important. For example, the repair of bimetallic heating radiators is not very different from the repair of any others, it all depends on the specific situation. Next, we will consider in detail how to find, localize and eliminate the malfunctions in heating radiators.

Types and design of heating radiators
In this article, we will analyze the sequence of repair of such types of radiators as:
- heating steel radiators,
- aluminum heating radiators,
- cast iron heating radiators,
- bimetallic heating radiators.
When repairing, the design of the radiator should also be taken into account. The main types of structures are four:
- Sectional radiators - collected from separate single -type sections, reliably fastened to each other.
- Monolithic radiators-are one large section-corps.
- Tubular radiators - does not have a unifying case, because The coolant circulates through pipes, which make up the radiator body. Often made in non -standard forms and sizes.
- Panel radiators. They consist of two metal plates that are cooked among themselves.
In order to start repairing the heating radiator, you need to know what main and additional elements, details and components are included in its design.
General device of radiator batteries
Consider the components and parts that equip heating radiators. Depending on their type and design, components and additional devices will be different, but in general, the list of possible components, the following:
- sections and tubes - channels inside which the heat -growing liquid circulates,
- nozzles - are connected to the pipes for the supply and removal of the coolant,
- detachable rings - close the output of the pipe from the wall panel,
- plastic rod - fixes the detachable rings,
- traffic jams - plugs on the sides of the radiator,
- ball crane with a valve - for overlapping the circulation of the coolant,
- maevsky crane - for manual dumping in the heating system, as an option, an automatic pressure tap is installed,
- the heat regulatory head, with which the room temperature is tuned,
- steel bushings, intersecination nipples, silicone gaskets - place sections in places of connection,
- clushes, counter -players and brackets for attaching heating radiators.
The set of aluminum heating radiator sometimes includes a circulation pump, which provides uniform heating of the room. It is also used for other radiators when the lower connection of the heating system is installed, i.e. Pipes approach the radiator from below. In this case, the use of the circulation pump is necessary, otherwise the level of heat loss will increase significantly.
Signs and causes of heating radiators breakdown
Possible causes of damage and breakdown of heating radiators:
- Initially, an incorrectly selected radiator. Depending on the diameter of the pipes, pressure and water temperature in the heating system, various types of radiators are set.
- Incorrect connection of the radiator to the heating system pipes.
- Tough operating conditions of a centralized heating system. The increased acidity of the coolant and sharp pressure drops lead to electrostatic and electrochemical corrosion of the metal.
- The coolant of poor quality in the heating circulation system forms a plaque at the joints of the sections and at the places of fastening of the pipes.
- Poor quality coolant clogs the radiator sections and the radiator as a whole. This makes it necessary to wash them periodically.
- Degradation of intersecration gaskets and the destruction of threaded nipples. It is necessary with a certain periodic to replace the gaskets between the sections of the radiator.
The main signs of breakdown and damage to heating radiators, the following:
- during the heating season, the rooms became colder than usual,
- at the joints of the sections and in the places of fasteners, a plaque formed,
- there was a leak.
If the heating radiator is very old, it is best to replace it. Modern models are more effective, have high thermal conductivity - the house will become warmer, and heating costs will decrease. In addition, new batteries are compact and are distinguished by a beautiful design.
In the case when it is not possible to change the radiator, it is necessary to correct the breakdown as soon as possible. The best solution is to contact specialized services or resort to the help of professional masters. But you can also try to repair heating radiators with your own hands.
Repair of sectional heating radiators with your own hands
Serving radiators include the vast majority. First of all, it is cast -iron and bimetallic, less often metal.
Of course, the preventive repair of heating radiators is best done before the heating season or after its completion. However, we often begin to do something only when the problem becomes critical. The main reason why it is necessary to repair is a leak of hot water. Therefore, the instructions are given below how to quickly carry out the repair of the radiator with your own hands and get rid of the leak:
1. Diagnize the leak. Often the place where the water flowed from is visible with the naked eye. But it happens that it is difficult to identify it. In this case, the radiator must be dismantled and loaded into the bathroom with water. From the place where the hole was formed, bubbles with air will begin to rise. However, most often there is no need to remove the battery, and the repair is carried out locally.
2. We prepare the tool. When the site is determined, it is necessary to proceed to the repair of the radiator. To do this, prepare the following tools and materials:
- thin steel cable,
- putty. You can use the choice: a mixture of epoxy and metal (bronze or aluminum) powder; thick zinc white; polymer or powder sealant; “Cold welding” (pay attention to ensuring that it is moisture -resistant and withstand the temperature up to 100 ° C),
- a canvas, a bandage or other fabric for applying a putty,
- metal clamp. If it is not - isolet (or rubber) and wire.
3. We equip the repair site. Under the battery, put an oilcloth, a waterproof fabric or a piece of film. On top - a large rag that absorbs water well. If necessary, put a pelvis or a bucket for collecting water nearby.
4. We clean up the leaks. Most often, the place of leaks is the joint between the sections of the radiator. In this case, it is necessary to remove the old winding, remove pieces of the destroyed gasket and layers of paint. Use the string (thin cable with nodules at the ends) and clean the damaged joint to the metal. Rinse the cleaned area with gasoline or acetone so that the new winding is firmly fixed on the radiator.
5. We cover the damaged area of \u200b\u200bthe radiator. Mix epoxy resin and metal powder, apply the composition to a narrow tape made of fabric. Win the tape with the mixture to the joint in two or three layers as tight as possible. If zinc white is used as a smearing agent, then in four to five layers. When using "cold welding", you need to cut off a small piece from it and knead it with your hands until a homogeneous consistency. They apply welding around the circle of the junction, you do not need to use the fabric tape.
6. We fix the smeared area with a metal clamp. Put the clamp over the putty. Cut it and securely fix it with bolts and nuts. The connection of the clamp should be in the opposite place of the course. If there is no clamp, use an insulating tape or a piece of rubber. It is better to cut rubber from an elastic medical tourniquet or a bicycle chamber. Wrap the tape or rubber into several layers, twist the edges tightly with a metal wire.
When the heating season is over, it is recommended to replace a defective heating radiator or at least its damaged sections. In the absence of such an opportunity, you should remove the old winding and process the place of course over the same scheme. This must be done before the next heating season, so that the new winding has time to dry well. Repair of cast -iron heating radiators is carried out in the same way.
Repair of aluminum heating radiator method
In some cases, damaged areas of aluminum radiator must be sold out. In the presence of skills in working with a soldering iron, it is not difficult to carry out such a repair. However, keep in mind that aluminum and its alloys are poorly soldered, so this work needs to be done extremely carefully. So:
- prepare the surface for soldering and apply an iron-drift flux on it;
- wipe the damaged area with a heated soldering iron;
- when the rosin spreads over the surface, enter a tin-sungau solder with an admixture of iron sawdust.
Soldered aluminum radiator is recommended to be redone again. For this:
- Wash the old layer of paint with special washing.
- Carefully process the radiator with sandpaper.
- Apply heat -resistant paint or enamel in an even layer from top to bottom. If the radiator is sectional, start painting from the sections between the sections. Keep in mind that when painting, the radiator should be cold.
Some tips and recommendations for increasing heat in the house
Finally, some tips to improve the operation of heating radiators and heating system as a whole:
- Painting of the radiator (in particular, cast iron) in dark color increases the fraction of heat, allotted by radiation.
- The recommended distance from the radiator to the windowsill is 100 mm, and from the wall to the battery - 20 mm. Otherwise the heat flux is disturbed, and the efficiency of the heating system is reduced;
- To increase thermal radiation directed into the room, attach a heat -insulating film with a foil surface to the wall behind the radiator.
- The optimal distance from the floor surface to the battery is 120-150 mm. If you do not follow this rule, sharp temperature differences will cause drafts in the house;
- With the reverse connection (when hot water is supplied to the radiator from below), the total system power decreases by about seven percent.
- The effectiveness of the heating system also significantly affects the installation site of the radiator. The maximum effect gives placement under the windowsill-96-97%. If the battery is in the niche in the open form, then the effectiveness is reduced to 93%; If the radiator is partially closed-up to 88-93%, if completely-up to 75-80%.
