Repair of the heating system - we care about the "health" of

Heating

Without proper maintenance, no heating system can operate for long. Just a few years and the risk of leakage increases, and even with the pressure in the pipes can cause problems. A person can cope with minor defects independently, but in the case of serious problems, the help of specialists will be needed. In any case, it will not be superfluous to get acquainted with what needs to be done in an emergency.

Repair of the heating system

What threatens to neglect in relation to the heating system

Maintenance and repair of heating systems are interrelated concepts. If maintenance is performed irregularly (or not at all), then it is possible to find out about the deterioration of the state of individual elements only when a pipe breaks through or something else equally unpleasant.

Maintenance allows you to identify at the early stages such possible defects as:

  • pipe corrosion (reducing the wall thickness of the pipe increases the risk of its gust);
It can be seen that due to corrosion the wall thickness has decreased significantly

Note! This is especially true for residents of high-rise buildings, where water hammer occurs quite often. If the pipe is old, it may well burst.

  • problems with tightness of pipe joints;
  • air plugs in radiators.

Another negative consequence of the devil-may-care attitude to the state of the heating system can be considered that the defects themselves will manifest themselves fully only at the start of the heating season. Well, if this happened in a private house - the heating can simply be turned off for the period of repair. But in the high-rise building, the heating is turned off - the whole story, because ZhEKi are famous for their slowness

Repair of heating systems is most often the result of the fact that the examination was not conducted for a long time. And if it came to extremes, then you need to at least know what to do in a critical situation. To do this, it will not be superfluous to familiarize yourself with the main types of faults in heating systems - some of them can be corrected by yourself, but some will have to be left to specialists.

Types of defects in heating systems and how to eliminate them

For example, we consider the procedure for eliminating the most common failures of a typical heating system.

  • pipe rush - is a consequence of excessive thinning of the wall and with the possible hydraulic shock. The only way to repair is to replace the damaged area. As a temporary measure, you can consider the imposition of a repair clamp, the price of such a device is cheap, so the repair will not be very expensive;
Pipe crack
  • flow of joints - if a plug-in connection is used, it is enough to turn off the heating system for a while, disassemble the connection and reassemble it using flax winding. It is possible that this will solve the problem;

Note! In addition to turning off the heating, you will also need to drain the coolant from the pipe. So this is quite a troublesome job.

  • barely warm batteries - a typical indicator that the canal inside the radiator is blocked and only its cleaning will help. If a bypass was installed in front of the battery, you can do without turning off the heating; it is enough to turn off the battery from the heating circuit, remove, drain the coolant and clean it. This task can also be done with your own hands;
The thermogram of the battery clearly shows that the extreme sections almost do not work
  • flow between battery sections - most likely, the nipple burst, to eliminate the damage, you need to completely move the battery.
Battery leakage

Problems can be observed with the circulation pump:

  • after the summer idle time, quite often the pump simply does not rotate, the reason for this is shaft oxidation. In this case, you will have to remove the engine and manually rotate its wheel;

Note! In low-power models, it is sometimes possible to rotate the shaft with a conventional screwdriver; at the end, the manufacturer does a serif specifically for this.

The shaft can be turned with a simple screwdriver
  • in the absence of a filter in front of the pump in a foreign object may simply block the operation of the device. In this case, it is enough to manually dismantle the casing and remove it;
  • the cause of periodic spontaneous shutdowns of the pump can be a thick layer of scale on the stator shirt, the repair instructions consist in the descaling of the stator shirt;
  • damage to the fuse can also cause problems with switching on the pump;
  • strong vibration is a consequence of the wear of the bearing, in which case only its replacement will help.
Circulation pump device

In addition to these, you can highlight the problems with the electric part of the pump. For example, if the 3-phase pump is not properly connected to the network, a reduced pressure is observed, and the required circulation of the coolant is not ensured.

On the work of special services

To maintain the heating system in working condition requires regular inspection by experts.

Also, the list of services provided by specialized companies includes emergency, current and capital repairs:

  • emergency repair - elimination of problems occurring directly during the heating season. This may include the elimination of such faults as a fistula on the pipe, the lack of hot water in the riser, heating radiator leakage, etc. In any case, to eliminate the malfunction, it is necessary to turn off the heating of a part of the house, so that work is carried out as soon as possible;
The classic example of a breakthrough worn-out heating main
  • Maintenance - carried out in preparation for the heating season. The list of works includes checking all stop valves, if necessary, rewind lock nuts, eliminate fistulas on pipes, replace strongly corroded heating pipes;

Note! Modern flaxen have an unpleasant feature - burn out over time. Therefore, periodically they have to be restored.

  • at major repairs a defective statement for the forthcoming types of work with an indication of the types of work and the cost of materials is necessarily compiled. Works on the complete replacement of heating pipes, radiators, the installation of new valves and so on are being carried out.
Defect List Example

From the point of view of the law, the customer is obliged to hold a tender for overhaul repair. Ideally, a dozen or two organizations will compete for the right to perform work, in the end, the one that will take on the task at the lowest cost will win.

In practice, often the overhaul is given without a tender to the service organization. This is a kind of guarantee of quality - after all, it will be unprofitable for this company to try to deceive the customer.

Note! Only those enterprises that have the right to render heating repair services are allowed to submit applications for participation in the tender, that is, according to the classifier, the OKDP code 453 was specified during registration.

Preparing for the heating season

It is clear that the ideal time to prepare for the heating season can be considered summer-early autumn. The heating system does not work at this time, so nothing will prevent a specialist from checking every element of it.

In preparation for the heating season, specialized companies, as a rule, offer a comprehensive check of all components of the heating system, ranging from checking the tightness of the joints and ending with checking the efficiency of the circulation pump.

The list of services provided includes:

  • inspection of the heating boiler (it is important for owners of autonomous heating), replacement of defective parts;
  • check the operation of the circulation pump, its cleaning;
  • check the degree of clogging of pipes, wall thickness;
  • cleaning of radiators under pressure;
In the photo - washing the radiator under pressure
  • check tightness of regulating valves, its replacement;
  • replacement of worn pipe sections with new ones;
  • system operation diagnostics.

It is also important that such companies provide a guarantee for the work performed. So in the winter, when an emergency situation arises, the elimination of consequences will be carried out free of charge.

Summarizing

Problems with the operation of the heating system are a rather unpleasant thing, because they only appear during the heating season. And their removal is associated with certain difficulties - after all, you have to turn off the heating for the period of repair work. Timely inspection and preparation of heating for the winter will avoid these troubles.
