Repair of heating radiators
Heating malfunctions in a private house associated with battery failure:
1. Installed radiators of poor quality.
2. Incorrect installation of batteries.
3. A low quality heat transfer fluid is used, the operating conditions of the equipment do not correspond to those specified by the manufacturer (for example, exceeding the operating pressure).
4. Damage to the joints of radiators with pipes by corrosion.
5. Worn gaskets or threaded nipples located between the sections.
6. Deterioration of batteries as a result of prolonged use.
If the batteries are old, permanent repair is almost pointless. In this case, the best solution is to purchase and install new radiators. For relatively new equipment, which is equipped with heating a private house, the master will find and eliminate the existing malfunction.
Installation of a heating system in a turnkey apartment
But first, you will have to calculate the number of taps and plugs for each room, the footage of pipes, their diameter, how many radiator sections are required for a particular room, and so on.
If the installation of heating in an apartment is carried out by professionals, you can safely exclude special tools and equipment for soldering or welding from the shopping list. The price will be even lower if an expert proposes an optimal battery model.
We install heating systems, including underfloor heating, in Moscow and the Moscow region. The cost of work with us is affordable, despite the high quality of services. We guarantee the reliability and durability of the system, as well as the absence of leaks and other problems. If you want the house to be warm and cozy - call us!
There are two types of repairs to heating systems:
1. Capital - is performed during the reconstruction of a building or the wear of a large number of units and parts. It may consist in replacing a boiler or other type of heating devices, partially or completely replacing pipes, installing additional radiators, and installing a warm floor. It is done quite rarely if high-quality materials and equipment are selected when creating a heating system.
2. Routine repair is the repair or replacement of faulty system elements. This can be the elimination of a leak, minor repairs to the heating boiler, etc. This type of repair is usually carried out without prolonged interruption of the system and requires lower costs.
Cottage heating repair
Repair of heating a cottage may be required in case of improper installation of pipes or the purchase of low-quality products. An autonomous individual heating system is installed in the buildings.this determines certain features of the maintenance and operation of the installation. Users should monitor the condition of the heating radiators in all rooms. In addition, it is necessary to monitor the quality of the equipment and the operating parameters of the equipment. Therefore, the installation of the system must be carried out by a professional who can guarantee compliance with all regulations and existing rules.
Also, accessories and pipes should be installed so as to provide easy access to work. This will facilitate the process of locating the leak. Since it is this breakdown that is the most common. The quality and speed of repair work will directly depend on the experience and qualifications of the contractor. An experienced specialist will offer the best way to solve the problem, taking into account the client's requirements. The owners of cottages are obliged to carry out preventive measures and scheduled repairs of the heating system.
It includes the following list of works:
- Determination of leaks and subsequent elimination;
- Repair of valves and taps;
- Replacement of certain nodes when;
- Carrying out measures for the modernization and replacement of equipment.
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 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 an optimal scheme to eliminate it. Before making repairs to the heating circulation pump, turn off the system and wait until the coolant has cooled down. This can be avoided if a bypass is installed on the pumping unit. It is enough to redirect the flow of hot water along the spare circuit.
Independent repair of pumps for heating is carried out only after a detailed acquaintance with the design features of a particular model. Then the device should be dismantled for further restoration of operability. There are several causes of malfunctions, after the identification of which, do-it-yourself repair work on the heating pump is performed.
Let's 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 out due to voltage surges in the network. The solution is to replace the fuse;
- Increased operating noise. To repair pumps for heating, 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 when working. Most likely the bearing on the shaft is out of order. To repair the heating circulation pump, you will need to replace it;
- Incorrect rotation of the blades. Check the connection phase, as well as the correct installation of the pump;
- Small 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 the circulation heating pump, the condition of these elements is first checked. Almost all models are designed to replace components. But before purchasing, you need to choose the right components by writing out the brand of the pump and its model.
There must be sealing grease on the gaskets and pump nozzles. If it is absent, it is necessary to reapply it.
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 batteries will help not only 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 rusting process - the reduction of pipe walls. They do not withstand the pressure of the system, a gap is formed. To quickly fix the problem, you can make a temporary repair of the heating radiator with your own hands. It is best to use cold welding for this. First, you need to check whether it is designed for application to the material of manufacture of the radiator.
Below is the procedure for carrying out self-repair of heating batteries:
- Disconnect the radiator from the general heating system.
- Determine the place of depressurization and clean it from dirt, paint and grease.
- Prepare hot welding solution. If it is two-component, you should act strictly according to the instructions from the manufacturer.
- Do-it-yourself heating radiator repair - we apply cold welding to the fabric base and wrap the leak.
- For better sealing, it is recommended to secure the patch with a mounting strap. 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 final drying of the cold welding.
Doing such a repair of a heat supply radiator with your own hands will only temporarily solve the problem. The best option for restoring the working capacity of the radiator is replacing the section or using electric (argon) welding.
After completing the restoration work, you should remove the air plugs from the radiator by opening the Mayevsky valve.
Setting up heating systems
Setting up the heating system of a private house allows you to balance the heating system and provide many benefits:
- lack of noise during system operation; - easy control of equipment; - economical consumption of resources; - long service life.
A distinction is made between coarse and fine adjustment of the system. The first changes the thickness of the pipes contained in the wiring and directed to the radiators, as well as the number of batteries used. Precise adjustment is mainly the adjustment of the heating system valves.
Basic conditions for correct balancing:
1. Possibility of smooth and accurate limitation of the coolant flow by valves for regulating radiators. The use of ball valves is excluded.
2. At the time of adjustment, the premises in which it is made must be fully exploited, to the extent that this will occur in the future.
Choice of materials
Before starting installation work, it is necessary to carefully consider the choice of equipment.
Pipes
Installation of heating systems is carried out using the following types of pipes:
- Cross-linked polyethylene (both for the radiator network and for water-heated floors)
- Metalloplast
- Polypropylene reinforced with fiberglass or aluminum
- Cink Steel
- Copper
- Brass
- Stainless steel
Unreinforced polypropylene pipes have a maximum heating temperature of 60˚C and therefore heating systems from them are not installed.
Steel black or galvanized pipes have excellent strength and are resistant to high temperatures in superheated water. However, they are susceptible to rust and are more difficult to install. The prices for these materials make it advisable to use them for piping furnace and boiler rooms.
Plastic pipes of small cross-sections are durable, easy to install, but have limitations in operating temperature and pressure.The laying of plastic heating piping systems is not practiced in those areas where emergency operating modes are possible. For example, at the outlet from hot water solid fuel boilers and drainage discharge lines in furnaces.
Copper, brass, stainless steel pipes are rarely used due to the high cost of the material and the need to use special tools when performing installation work.
Today, the installation of heating, using pipes made of cross-linked polyethylene (with hidden laying) or pipes made of reinforced polypropylene (with open laying), is the most optimal option. For piping boiler equipment, it is advisable to use copper or reinforced polypropylene.
Heating devices
The choice of the type of heating radiators depends, first of all, on the efficiency of their heat transfer, the pressure of the water heating systems, the heat carrier used, the requirements for their appearance, and cost.
Depending on the material of manufacture and design features, radiators are of the following types:
- Steel panel
- Steel tubular
- Bimetallic sectional
- Aluminum sectional
- Cast iron
In closed-loop circuits, the oxygen supply to the water is minimal and heating systems can be installed with any type of radiator. The limitation is imposed by the heat carrier used.
The best results in the middle price segment are shown by steel panel radiators. When using bimetallic sectional radiators, it must be remembered that the coolant (if it is not water) can corrode the gaskets between the sections and the radiator will flow.
What malfunctions exist? Eliminating them
Naturally, in a country cottage, or rather in its heating system, problems will appear sooner or later. Problems and malfunctions that occur inside the water heating are eliminated on their own, without the help of a master. But if a situation arises when you have to replace or perform serious work with a heating boiler, then you cannot do without a professional specialist.
Let's take a closer look at the problems that can arise in the operation of the boiler and radiator:
- Low level of heat transfer from the radiator. Such a low level can occur for several reasons:
- the presence of a large amount of air in the heating system, the formation of air jams;
- extremely long service life. At the same time, there was practically no care for the radiator and the heating system itself. It is also possible due to the fact that an extremely low-quality radiator was used, there may be a large amount of dirt inside the battery;
- a sharp drop in pressure, leaks;
- previously performed installation work was performed poorly, there are violations;
- the usual shutdown of the heat supply tap. But this option is rare.
Let's start in order and analyze a little how to fix these breakdowns. If there is a large presence of air inside, then the best solution would be to launch the descent with the help of cranes. Just in case, put a container underneath if there is a leak.
Also, if it was not possible to fix the system, then it is worth doing a complete flushing of the system. We unscrew the cork, there should also be a container from below. We drain all the water. We do this until there is clean water. If this method does not help, then we perform a complete flush.
Do not forget that the pump and the expansion tank are responsible for the pressure in the system. In order to increase the pressure in the system, turn the supply valve. Next, on the pressure gauge, we look at how much you need. This kind of problem is often found in double-circuit boilers.
- Low pressure in the system. What are the reasons for the breakdown here:
- the presence of leaks;
- air leaves the system with difficulty;
- if new radiators are installed, the rollback time has not yet passed.
In order to solve these problems, you must first find the place of the leak.We take a close look at the entire system. Where there are holes, there is a white coating, and it is along this that you can find a leak. It is also extremely common to see how the heating system is incorrectly filled. Before the very first work, experts advise releasing unnecessary air from the system. Otherwise, air pockets may occur.
- Lack of circulation. The problem is common enough for many owners of private buildings. There are two ways to solve the problem of heating in a room. Either using a pump or convection. If there is no circulation in the radiators, then they will not heat. The reason often lies in the presence of dirt in the radiator or pump malfunction.
By the way, all these types of heating repairs are also used in office buildings. The heating problem is so common that, according to statistics, every second person is faced with it.
Before you start repairing the heating system or repairing radiators, do not forget that you will have to make an approximate estimate for the repair! You should initially know how much money it will take you to carry out this type of work.
Repair and replacement of radiators
If the radiator leaks, it is not at all necessary to replace it with a new one. It will be cheaper to repair. Our specialists perform this work in the following sequence:
- a tool and putty are being prepared to eliminate leaks (cold welding, special sealants);
- water is blocked and drained from the circuit in which there is a leak;
- the leak point is cleaned and degreased;
- the sealant is applied to a strip of fabric, which is wound around the joint in several layers;
- on top, the fabric is fastened with a clamp.
The repaired radiator will work reliably, but it is better to replace it with a new one by the next heating season. If you choose, it is better from aluminum, and not from cast iron. Such a heating device is much lighter than a cast iron radiator. In addition, aluminum conducts heat better than cast iron. Steel batteries are also popular, they also have good thermal conductivity and look good.
