Why does the gas column go out? Repair of gas columns. Gas water heater

Despite the fact that the technology of hot water and heating to multi-storey and private residential buildings are constantly evolving, most of the apartments still have gas columns installed. Often, users of these devices may encounter a problem - the column will go out after a while, or even refuses to ignite. Similar problems with such equipment are not uncommon. Let's find out why the gas column will go out and how to fix it.

Device

Before you perform the repair of the column, you should find out how it is arranged. From the design in most cases depends and the method of repair. We will not delve into the structure of each individual column. But the general principles should be known to every home master. In order to avoid such annoying breakdowns, it is necessary to select the right gas flow-through water heater. Feedback is the best indicator of quality. Users write pluses and minuses, and on them it is possible to be guided at purchase. Centralized hot water supply systems appeared relatively recently. Previously, the issue of water heating was solved by various methods. The most common solution was the so-called storage solid fuel heater - "Titan". This system was heated with coal, or with wood and fuel oil. The water in the boiler of this equipment had to be preheated beforehand. So, to take a bath, it took one hour to warm up the water. Naturally, it was very, very inconvenient to operate such a system. The problem of the time needed for heating was decided by the creation of gas columns. People gladly accepted and began to operate a gas water heater running. Reviews about this equipment are positive. But this concerns only high-quality devices "Bosch", "Gorenie", "Zanussi".

So, a typical gas column warms ordinary running water with gas from the main. In order for the heating process to be rapid, a heat exchanger is used in the design. In it water is distributed through thin tubes located directly above the burner. Due to this, it is possible to heat water very quickly (almost instantaneously). The consumer does not need to store it in special tanks.

This is the fundamental structure of the standard column. All the rest in the design serves to ignite fuel, adjust the temperature of heating the liquid, ensure the safety of the gas device.

Columns by type of ignition

The column lights up differently. This depends on the particular design. When igniting from the igniter, the gas lights up either by piezo-ignition or by matches manually. This is true for older models. The pilot burns constantly. There are also columns where there is no ignitor, and instead there is a piezo spark. Finally, there are solutions with an electronic ignition system. This system is structurally similar to the car ignition system. Works automatically.

Protection systems

In most gas columns, which are in many apartments and houses, a mechanical safety system is installed. Even the most modern unit, in which there are many electronic sensors and devices, has in the design a mechanical connection between the membrane in the water supply system and the valve installed in the gas pipe.

The gas will be supplied only when the water pressure force is sufficient to pressurize the membrane. The principle here is very simple. If there is no water, the gas will not be supplied to the column burner. If you turn off the tap and the water goes off, the column will light up.

Common Problems

Let's see why the gas column goes dead. Damping can be caused by a number of reasons. A sensor may be activated that detects a gas leak. There may be problems with the chimney work. The clogging in the ignitor also often causes damping problems. Sometimes the automation breaks down.

Often the problem of damping is related to the quality of fuel. Some gas farms supply not pure gas, but diluted. Such a low-quality fuel is easily determined by the orange color of the flame. If serious automatic protection systems are installed in the column, they will disconnect the system. Also it is worth paying attention to gas leaks. Even non-serious leaks are the reason why these units fail. It can help repair gas columns at home. But it's only worth treating professionals - gas is a joke with gas.

Weak or missing traction

Among the main reasons for such unsatisfactory work may be a weak pull, or its complete absence in the ventilation duct. However, the most popular reason is a locked plastic window. As a result, there is no air flow. The column will overheat, and eventually the thermal protection relay will work. If you open a window or door, and the column lights up and does not go out, in this case the cause is due to overheating.

Clogged chimney

If too many combustion products have accumulated in the chimney or if there are foreign objects inside, a protection system will operate in the heater system, which will block the gas. To check for what reasons the gas column lights up and then dies in this case, it is possible in the following way. It is necessary to open a window or window, light a match, and then attach it to the chimney hole. If there is no traction, then the flame will not deviate. Eliminate the lack of traction or lack of it can be cleaned chimney and ventilation duct. In this regard, it is best to turn to specialists who will clean the chimney for a small amount.

Low battery

Another reason why the gas column will go out is battery power. If the column is equipped with an auto-ignition system, and it is powered by batteries, then it is recommended to replace them. Also in this case, it will be superfluous to test the button responsible for starting and stopping.

Water node problems

The next reason why the gas column dries out is the absence and weak pressure of water. When opening the tap with cold water the head of its supply will be insufficient, then this is the problem of the filing companies. Because of this, the gas column will dry out. What to do? It is necessary to understand the reasons for the weak pressure. If cold water is supplied at a higher pressure than hot water, then this column work is connected to the water part of the unit. Among the reasons - clogged filters, deformation of the membrane. Often the reason lies in the fact that the hot water supply pipe is clogged. If there are additional filters (if they are clogged), the water head may also decrease significantly.

How to troubleshoot?

The first thing that experts recommend is to perform cleaning and washing the filters. It is better and at all to replace the cleaning elements with new ones. If the cause is related to the water part, you should call the utility companies and find out from them why the system has such a weak pressure. Often the problems are solved by cleaning the pipes and the column itself. It may also be necessary to replace the membrane. When questions on the gas part is better to use the service "repair of gas columns at home." Professional masters will carry out repairs as safely as possible.

The column lights up and goes out

About these cases you can hear from the owners of this equipment quite often. The fault can be rectified by adjusting the volume in which hot and cold water is supplied. It is not recommended to dilute excessively hot water by adding cold water. This will lead not only to the dying flame, but also to the violation of the operating rules of the unit. To adjust the water supply, reduce its level in the tap.

Conclusion

So, we found out why the wick in the gas column will go out. After all the malfunctions are eliminated, the gas unit, which makes life more comfortable, will work stably.
