Repair of copper, plastic, steel heating pipes

Repairing a heating system is an expensive, complex, but necessary procedure. It must be carried out regularly, with a certain frequency, both in a city apartment and in private real estate. If you do not pay attention to this design, over time it will begin to fail until it falls into disrepair. The drop in pressure and temperature is just the beginning. The most tragic consequences are manifested in leaks and breaks in the main line. This is dangerous to health and is fraught with large material costs. The scope of repair of the heating system is determined by its age, degree of wear and existing damage. Based on the diagnosis, a decision is made on local or major intervention.

Overhaul of the heating system

The main indicators of a heating system are stability and reliability, which directly affect the living conditions of people in the building. Stopping the system or malfunctioning of certain of its components forces professional repairs to be performed to restore operating condition.

Our team of technicians works not only to restore the defective heating system, but also to improve it, thereby increasing the efficiency, reliability and economics of heating.
At the initial stage of a major overhaul, the heating system undergoes a visual inspection. Initially, EuroHolod specialists assess the situation taking into account all the customer’s comments. The client receives information with a proposal to replace specific equipment so that the system begins to function better. A detailed inspection is accompanied by drawing up a overhaul plan, after which the customer is given the opportunity to familiarize himself with the estimate for maintenance.
When performing repair operations, the specifics of the heating system, as well as the structural characteristics of the serviced object, are taken into account. It is recommended to draw up a preliminary application for performing these operations in order to timely complete all repair stages and prepare the heating system for seasonal operation.

Description of repair measures

During a major overhaul, valves and other shut-off valves are changed, the working condition of pipelines is restored, and their specific elements are changed (if necessary). In addition, air collectors are installed and a sludge separator is installed.

The overhaul carried out by the company’s specialists will reduce heat loss during the operation of the heating system and increase its reliability. The operation of the equipment will be long and uninterrupted.

Major and current repairs of heating systems

Current repairs are the repair and replacement of worn-out system elements. As a rule, this involves eliminating leaks, minor boiler repairs, etc. Such an event usually does not require a long shutdown of the entire system and costs little. Major repairs become necessary during periods of major repairs and reconstruction of buildings, in cases of wear of all or many parts and assemblies:

replacement of a boiler, furnace or heat accumulator;
complete or partial replacement of heating pipes;
installation of new radiators or underfloor heating systems.

The need for major repairs arises infrequently; sometimes systems last for several decades without serious breakdowns. The frequency of replacement and retrofitting of the system depends on the quality of heating devices and pipes that owners choose for specific buildings. Therefore, when choosing, you should pay attention to the products of companies with a good reputation and the technical characteristics of the models.

Chronology of current repairs

During routine repairs of the heating system, the following activities are performed:

If defects are detected in the pipelines, they are eliminated or the damaged element is replaced. Eliminating pipeline leaks contributes to its full and safe operation.
Specialists replace or repair shut-off valves, replace faulty pumping equipment and automatic control systems.
The shut-off valves are checked and the thermal insulation of the pipeline is repaired (if its integrity is damaged).
Heat exchangers, radiators and risers are washed. This is required in order to improve the functioning of the heating system. If the system is characterized by insufficient heat transfer, a comprehensive flushing is performed. It is advisable to install additional fasteners to increase the safety of the system.

Before starting routine repairs, a detailed check of the condition of the components and elements of the heating system is carried out. The system is also analyzed for wear levels.

Autonomous heating repair rules

A breakdown of an autonomous heating system cannot always be identified immediately. Emergency repair of the heating system is required only if there are obvious malfunctions - leaking radiators, pipes or boiler failure. But it is more difficult to determine a malfunction based on indirect signs.

There are several factors that indicate the need for heating repairs in a private home. 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 in a country house will help eliminate these problems.

Before restoring the functionality of the autonomous heat supply, the following actions must be performed:

Turn off the boiler. For solid fuel models, it is recommended to limit the air flow into the combustion chamber to reduce heat transfer to a minimum level.
Determine the breakdown area and block the access of the coolant in this area.
Choose the optimal technology for heating repairs in a private home. It depends on the type of failure - depressurization of pipes or radiators, failure of the boiler, expansion tank, circulation pump.
Carrying out repair work on the heating system in a private home.
Checking the functionality of the system, starting the heating.

This is a general scheme that has a number of nuances depending on the type of restoration measures. All influencing factors should be taken into account - the temperature outside, the type of coolant in the system (water or antifreeze), and the heating supply package. In some cases, it is better to make an initial emergency repair of the heating system, and then call specialists to professionally solve the problem.

To promptly repair heating systems in a country house, it is recommended to purchase kits for eliminating leaks in pipes and radiators in advance.

Plumbing repair

Planned or emergency repairs of the water supply system are carried out by the operating organization. In order to restore the water supply, leaks are eliminated, new shut-off valves are installed, and the existing circuit is cleaned of contaminants.

The duration of the repair depends on the complexity of the breakdown and the degree of damage to the line. In the most difficult situations, fragmentary replacement of the section is performed.

Along with plumbing repairs, sewerage maintenance may also occur. The main cause of malfunction in these networks is blockages. They accumulate on the walls of the pipeline, reducing its throughput. Removal of contaminants is carried out mechanically or chemically. In the second case, the material from which the pipes are made is taken into account.

Heating repair in an apartment

Restoring the functionality of centralized heating differs from the technology described above for autonomous heating. In many cases, you cannot repair the heating in an apartment yourself, as this may affect the heat supply parameters of the entire house.

First of all, it is necessary to notify the utility services with which the heat supply contract has been concluded. It is advisable to record the fact of the accident on a photo or video camera. Then, after consultation with representatives of the management company, try to make temporary repairs to the heating supply in the apartment. It is strictly forbidden to block common risers yourself.

Upon arrival of utility services, a report is drawn up, which indicates the following points:

Possible causes of the accident;
Measures taken for emergency restoration of the heating system in the apartment;
The consequences of an emergency are damage to walls, flow, interior items. An inspection of the apartment below is required.

It is important to remember that independent heating repairs in an apartment can only be carried out with the consent of the Management Company. Exceptions are those situations when a heating supply component is replaced with similar ones without affecting the heating of the entire house.

A copy of the accident report 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, emergencies occur with batteries and heating radiators. This is due to the peculiarities of their operation. Timely repair of heating radiators will not only help eliminate the accident, but will also make it possible to use this heating element in the future.

There are a number of reasons why a radiator fails. The main one is the rusting process - the reduction of pipe walls. They cannot withstand the pressure of the system, and a gap forms. To quickly resolve the problem, you can perform a temporary repair of the heating radiator yourself. It is best to use cold welding for this. You must first check whether it is designed for use with the radiator material.

Below is the procedure for self-repairing heating batteries:

Disconnect the radiator from the general heating system.
Determine the location of depressurization and clean it of dirt, paint and grease.
Prepare hot welding solution. If it is two-component, you should act strictly according to the instructions from the manufacturer.
Repairing a heating radiator with your own hands - apply cold welding to the fabric base and wrap the leak area.
For better sealing, it is recommended to secure 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 heating battery, you can reconnect it to the general heating system. But this should be done only after the cold weld has completely dried.

Carrying out such a repair of a heating radiator with your own hands will only temporarily solve the problem. The best option for restoring the functionality of the radiator is to replace the section or use electric (argon) welding.

After completing the restoration work, remove the air plugs from the radiator by opening the Mayevsky valve.

Heating pipe repair

Thanks to its convenient design, repair of heating pipes in an apartment or house can be carried out in several ways. The only complication is a temporary lack of coolant circulation. In an apartment building, this requires turning off the central riser. For an autonomous system, it is enough to deactivate the heating boiler.

The first thing to do when a heating pipe breaks is to protect the floor covering from moisture. You can use rags and containers for this. Then you can repair heating pipes without welding using available materials and tools. To do this you will need the following components:

Clamps. Their diameter must correspond to the cross-section of the pipe.
Rubber gasket. You can use an old bicycle tube for this.

Before performing independent repairs of heating pipes without welding, you should shut off the flow of coolant in this area. Then the depressurization area is cleaned. The next step in repairing heating pipes in an apartment is installing a rubber gasket. It is wound in several layers. The pressure should be tight and tight. Mounting clamps are used for fixation.

More efficient repair of heating pipes without welding can be done using a special kit. It includes a clamp and a rubberized gasket. It differs from homemade ones in the speed of installation and service life.

It is purchased in advance, as it is designed for pipes of a certain diameter. If the cross-section of the line is different, it is recommended to buy several different sets.

Repair of polymer heating pipes in an apartment can be carried out using a welding machine. A set of mounting fittings and a piece of pipe of this diameter must be available. To carry out restoration work, the following actions are performed:

The pipeline section is disconnected from the general pipeline;
Using special scissors, the defective area of the pipe is cut out;
A new pipeline is welded using a welding machine.

For temporary repairs 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, depressurization most often occurs at the joints. To solve this problem, you can re-solder or replace the entire section of the line.

Pipeline repair cost

The cost of repairing a pipeline line or section of it depends on several factors:

purpose of the network (transportation of drinking water, technical fluid, coolant);
method of laying the highway;
system device parameters;
the material from which the pipes are made;
degree of wear and contamination of the line;
external conditions that impede work;
terrain features of the site;
pipeline depth;
seasonality, weather conditions;
need for technology.

Work on installation and dismantling of lines is estimated in linear meters. The cost of repairing shut-off valves is determined taking into account the number of points.

If necessary, other operations associated with repair activities are performed. These works require agreement with the customer and are paid separately.

Heating boiler repair

Heating boilers are the most complex element of heat supply. It is almost impossible to restore their functionality in the event of a breakdown on your own. Therefore, before repairing diesel heating boilers or their other analogues, you should analyze all possible consequences.

First you need to check whether the warranty on the equipment is still valid. If this is indeed the case, you need to call specialists to fix the problem. Self-repair of electric heating boilers may result in premature voiding of the warranty.

But primary knowledge about the cause of the malfunction will help the specialist. You can describe the emergency situation over the phone. The company representative will take with him the optimal set of tools and components necessary for replacement.

Repair of electric heating boilers may be necessary in the following cases:

A sharp decrease in heating of the coolant;
Failure of the control unit;
Heat exchanger failure – leakage;
The influence of third-party factors that led to the breakdown - a sharp surge in voltage in the network, overheating of the coolant.

Often the reason for the repair of diesel heating boilers can be the quality of the fuel used. In this case, you can clean the injector yourself and check the primary fuel heating unit. If these actions do not solve the problem, you will have to call a specialist.

But there are a number of breakdowns that cannot be eliminated by repairing electric heating boilers. First of all, this 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 by specialists, a note about this fact is made in the warranty card. If the breakdown is due to a manufacturing defect in the equipment, you can request an increase in the warranty period.

Battery Installation

Their performance capabilities will depend on what type and model of radiator you plan to purchase. When choosing devices, you need to know:

features of the heat supply system and its operation;
pay attention to the size of the living space;
area of residence northern or warmer regions;
quality of insulation of the room, if any.

After the selection and purchase have been made, it is time to begin installation work.

The first condition, without which the installation cannot begin, is the presence of fastening materials or brackets. To prevent cold air from entering the room, it is necessary to install a radiator under the window. When installing, it is necessary to take into account a number of parameters - at least 15 cm from the floor and 12 cm from the window sill, a distance from the wall of approximately 5-7 cm.

There are different types of connecting radiators to the heating system:

one-sided;
cross;
lower;
single-pipe.

Cast iron radiator wiring diagram

It is believed that one-way connections are more efficient.

For preventive inspections and repair work, a pressure gauge, taps regulating the supply of coolants, a spirotop for bleeding air from the system and some other auxiliary mechanisms are installed.

The time required to repair and maintain the heating system will depend on the number of installed radiator sections.

Repair of circulation pumps

To increase the speed of movement of the coolant in the heat supply, a circulation pump is installed. Its breakdown will not only worsen heat transfer, but will also negatively affect the performance of the entire system.

Despite the apparent complexity of the design, you can repair the heating pump yourself. To do this, first determine the cause of the problem and develop the optimal scheme to eliminate it. Before repairing the heating circulation pump, you should turn off the system and wait until the coolant cools down. 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 heating pumps is carried out only after detailed familiarization with the design features of a particular model. Then the device should be dismantled to further restore functionality. There are several causes of malfunctions, after identifying which repair work on the heating pump is carried out with your own hands.

Let's look at 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 in the network. The solution is to replace the fuse;
Increased noise during operation. 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 has failed. To repair the heating circulation pump, you will need to replace it;
Incorrect blade rotation. The connection phase should be checked, as well as the correct installation of the pump;
A little pressure. Most often this is due to a clogged filter. In this case, it will not be necessary to repair the heat supply pump, but to clean the filter.

After long-term operation, some pump components lose their hermetic properties - the geometry of the impeller and shaft changes. To repair a heating circulation pump, the condition of these elements is first checked. Almost all models are designed to replace components. But before purchasing, you need to select the right components, writing down the brand of the pump and its model.

There should be a sealing lubricant on the gaskets and pipes of the pump. If it is missing, it must be reapplied.
