Even in the most reliable and modern heating system, a malfunction can occur. This may be due to the breakdown of individual components: radiators, pipes, pump or expansion tank. In some cases, repairs can be done by yourself. But for this it is necessary to know the features of its implementation, to determine the optimal set of tools and supplies for its implementation.
Autonomous heating repair rules
A breakdown in autonomous heat supply cannot always be detected immediately. Emergency repairs of the heating system are required only if there is an obvious malfunction - leakage of radiators, pipes or boiler failure. But it is more difficult to determine the malfunction by indirect signs.
There are several factors that indicate the need for repair of heating in a private house. First of all, a constant decrease in pressure in the system. The reason for this is a small leak. Another sign is the deterioration of the heat supply - a decrease in efficiency, uneven heat distribution. Timely repair of heating systems of a country house will help to eliminate these problems.
Before restoring the functionality of autonomous heat supply, the following steps must be performed:
- Turn off the boiler. For solid fuel models, it is recommended that air flow into the combustion chamber be limited to reduce heat transfer to a minimum.
- Determine the breakdown zone and block the access of the coolant in this area.
- Choose the optimal technology for the repair of heating in a private house. It depends on the type of failure - depressurization of pipes or radiators, failure of the boiler, expansion tank, circulation pump.
- Repair work on the heating system in a private house.
- Checking system performance, starting heating.
This is a general scheme, which has a number of nuances depending on the type of rehabilitation measures. All factors of influence should be taken into account - outdoor temperature, type of coolant in the system (water or antifreeze), heating supply package. In some cases, it is better to make an initial emergency repair of the heating system, and then call specialists for a professional solution to the problem.
For the quick repair of heating systems of a country house, it is recommended to purchase kits in advance to eliminate leaks in pipes and radiators.
Repair of heating in the apartment
The recovery of district heating is different from the above technology for autonomous. In many cases, you can not do your own repair of heating in the apartment, as this may affect the parameters of the heat supply of the entire house.
First of all, it is necessary to notify the utilities with which a heat supply agreement has been concluded. It is advisable to record the fact of the accident on a photo or video camera. Then, after consulting with representatives of the management company, try to make a temporary repair of the heat supply in the apartment. Overlapping common risers yourself is strictly prohibited.
Upon arrival of utilities, an act is drawn up, which indicates the following points:
- Possible causes of the accident;
- Taken measures for emergency restoration of the heating system in the apartment;
- The consequences of an emergency - damage to walls, flow, interior items.Be sure to inspect the apartment below.
It is important to remember that independent repair of heating in an apartment can be carried out only with the consent of the Management Company. The exceptions are those situations when a heating component is replaced with a similar one without affecting the heating of the entire house.
A copy of the accident certificate must be kept by the owner of the apartment until the issue of compensation for the consequences of heating failure is resolved.
DIY battery repair
Most often, emergency situations occur with radiators and radiators. This is due to the features of their operation. Timely repair of heating batteries will help not only to eliminate the accident, but also make it possible to use this element of heat supply in the future.
There are a number of reasons why a radiator fails. The main one is the process of rusting - reducing the walls of pipes. They do not withstand the pressure of the system, the formation of a gap. To quickly fix the problem, you can do temporary repairs of the radiator with your own hands. It is best to use cold welding for this. It is first necessary to check whether it is designed to be applied to the material of manufacture of the radiator.
The following is the procedure for self-repairing radiators:
- Disconnect the radiator from the general heating system.
- Determine the location of depressurization and clean it from dirt, paint and grease.
- Prepare a hot welding solution. If it is two-component, you should act strictly according to the instructions from the manufacturer.
- Doing repair of the heating radiator with your own hands - we apply cold welding to the fabric base and wrap the leakage site.
- For better sealing, it is recommended to fix the patch with a mounting clamp. If this is not possible due to the design of the battery, we apply an additional layer of cold welding.
After repairing the heat supply battery, you can reconnect it to the general heating system. But this should be done only after the final drying of the cold welding.
Doing such a repair of the heat supply radiator with your own hands will only temporarily solve the problem. The best option for restoring the radiator's health is to replace the section or use electric (argon) welding.
After performing restoration work, remove the air plugs from the radiator by opening the Mayevsky tap.
Repair of heating pipes
Due to its convenient design, repair of heating pipes in an apartment or house can be carried out in several ways. The only complication is the temporary absence of coolant circulation. In an apartment building, the central riser must be turned off for this. For an autonomous system, it is sufficient to deactivate the boiler.
The first thing to do when forming a rupture of a heating pipe is to protect the floor covering from moisture. To do this, you can use rags and containers. Then it is possible to repair the heating pipes without welding using available materials and tools. To do this, you need the following components:
- Clamps. Their diameter should correspond to the cross section of the pipe.
- Rubber gasket. To do this, you can use the old bicycle camera.
Before performing self-repair of heating pipes without welding, you must block the flow of coolant in this area. Then the stripping of the depressurization place is performed. The next step in repairing heating pipes in an apartment is installing a rubber gasket. It is wound in several layers. The clamp should be tight, with a stretch. Mounting clamps are used for fixing.
More rapid repair of heat supply pipes without welding can be done using a special kit. It includes a clamp and rubber gasket. It differs from the self-made installation speed and lifetime.
It is purchased in advance, as it is designed for pipes of a certain diameter. If the cross section of the highway is different, it is recommended to buy several different sets.
Repair of polymer heating pipes in an apartment can be done using a welding machine. There should be a set of mounting fittings and a pipe segment of this diameter. To carry out restoration work, the following actions are performed:
- The pipeline section is disconnected from the common trunk;
- Using special scissors, the defective area of the pipe is cut out;
- A new pipe is welded by the welding machine.
For temporary repair of plastic heating pipes without welding, you can use a special putty. It is important to ensure that it is suitable for this type of pipe.
In copper pipelines, most often depressurization occurs at the joints. To solve this problem, you can re-solder or replace the entire section of the highway.
Repair of heating boilers
Heating boilers are the most complex element of heat supply. To restore their performance in the event of a breakdown on their own is almost impossible. Therefore, before performing repairs of diesel heating boilers or their other analogues, all possible consequences should be analyzed.
First you need to check if the equipment warranty still applies. If this is true, then it is necessary to call specialists to fix the problem. Self-repair of electric heating boilers can lead to a premature termination of the warranty.
But primary knowledge of the cause of the malfunction will help the specialist. It is possible to describe the emergency in a telephone mode. The company representative will bring along the optimal set of tools and accessories needed for replacement.
Repair of electric heating boilers may be necessary in the following cases:
- A sharp decrease in coolant heating;
- Failure of the control unit;
- Damage to the heat exchanger - leakage;
- The influence of external factors that led to the occurrence of a breakdown is a sharp surge in voltage in the network, overheating of the coolant.
Often, the cause of the repair of diesel heating boilers can be the quality of the fuel used. In this case, you can clean the nozzle yourself and check the primary fuel heating unit. If these actions did not solve the problem, you will have to call a specialist.
But there are a number of breakdowns that cannot be fixed by repairing electric heating boilers. This primarily concerns the destruction of the housing and the lack of maintainability of the heat exchanger. In these cases, it is more advisable to purchase new equipment than to repair diesel heating boilers.
After the repair is completed, specialists in the warranty card make a mark about this fact. If the breakdown is associated with a factory defect in the equipment, an extension of the warranty period may be required.
Repair of circulation pumps
To increase the speed of the coolant in the heat supply, a circulation pump is installed. Its breakdown will not only worsen heat transfer, but also negatively affect the performance of the entire system.
Despite the apparent complexity of the design, you can do the repair of the heating pump with your own hands. To do this, first determine the cause of the problem and develop the optimal scheme to resolve it. Before repairing the heating circulation pump, turn off the system and wait for the coolant to cool. This can be avoided if a bypass is installed on the pump unit.It is enough to redirect the movement of hot water along the spare circuit.
Self-repair of pumps for heating is carried out only after a detailed familiarization with the design features of a particular model. Then you should dismantle the device to further restore performance. There are several causes of malfunctions, after the identification of which repair work is done on the heating pump with your own hands.
Consider the most common of them, as well as ways to solve the problem:
- The power plant does not work. First you need to check the condition of the terminals - the fuse on them often blows due to power surges. The solution is to replace the fuse;
- Increased noise during operation. In order to repair heating pumps, in this case it is necessary to remove air from the pipe. It is best to install an automatic air vent in advance;
- Strong vibration during operation. Most likely, the bearing on the shaft is out of order. To repair the heating circulation pump, it will need to be replaced;
- Incorrect rotation of the blades. It is necessary to check the connection phase, as well as the correct installation of the pump;
- Low pressure. This is most often due to clogged filter. In this case, it will not be necessary to repair the heat pump, but to clean the filter.
After prolonged use, some components of the pump lose their hermetic properties - the geometry of the impeller and shaft changes. To repair the circulation pump, the condition of these elements is first checked. Almost all models are designed to replace components. But before purchasing, it is necessary to choose the right components by writing out the brand of the pump and its model.
Sealing grease must be on the gaskets and nozzles of the pump. If it is absent, it is necessary to reapply it.
Repair of heating expansion tanks
The expansion tank is included in the heating safety group, ensuring the normal operation of the system. In open circuits, it can perform several functions - control of the coolant level and the unit for adding water. It practically does not fail. But in closed heating circuits, a breakdown of the expansion tank is a frequent occurrence.
Most often, repair of an expansion heating tank is caused by the destruction of the elastic membrane. But keep in mind that not all models have a collapsible design. Tanks of small volumes are made by welded methods - two parts of the steel body are connected in a non-separable way. In this case, the only option to repair the expansion tank is to purchase a new one.
Less common is damage to the case due to mechanical stress or rust. In the latter case, the design is also impossible to restore. If the depressurization of the housing is of a small nature, it is possible to repair the expansion tank of heat supply by the method of arc or argon welding.
For possible malfunctions of the heating system should be prepared in advance. Probable places of breakdowns are analyzed and schemes for their elimination are developed. Using this technique, it is possible to independently and quickly carry out heat supply repairs.
