Despite the fact that the technologies for supplying hot water and heating to multi-storey and private residential buildings are constantly evolving, gas stoves are still installed in most apartments. Often users of these devices may encounter a problem - the column goes out after some time of operation, or it refuses to light up at all. Similar problems with such equipment are not uncommon. Let's find out why the gas column goes out and how to fix it.
Device
Before you repair the column, you should find out how it is arranged. In most cases, the repair method also depends on the design. 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 choose the gas flow water heater correctly. Reviews are the best indicator of quality. Users write pros and cons, and you can navigate through them when buying.
Centralized hot water systems have appeared relatively recently. Previously, the issue of heating water was solved by a variety of methods. The most common solution was the so-called storage solid fuel heater - "Titan". This system was drowned with coal or wood and fuel oil. The water in the boiler of this equipment had to be pre-heated. So, to take a bath, it took one hour of time to heat the water. Naturally, operating such a system was very, very inconvenient. The problem of the time required for heating was solved by the creation of gas columns. People gladly accepted and began to operate a gas-fired instantaneous water heater. Reviews about this equipment are positive. But this applies only to high-quality devices "Bosch", "Gorenie", "Zanussi."
So, a typical geyser heats ordinary running water with gas from the main. In order for the heating process to be fast, a heat exchanger is used in the design. In it, water is distributed through thin tubes located directly above the burner. Due to this, you can heat the water very quickly (almost instantly). The consumer does not need to accumulate it in special tanks.
This is the basic structure of a standard column. Everything else in the design serves to ignite the fuel, adjust the temperature of the fluid heating, ensure the safety of the gas device.
Ignition speakers
The column lights up differently. It depends on the particular construction. When firing from the igniter, the gas is ignited either by piezo-ignition, or by manual matches. This is true for older models. The ignitor burns constantly.
There are also columns where there is no pilot light, but instead there is piezo ignition. And finally, there are solutions with an electronic ignition system. This system is structurally reminiscent of a car ignition system. It works automatically.
Security systems
Most geysers, which are in many apartments and houses, have a mechanical security system. Even the most modern unit, in which there are many electronic sensors and devices, has a mechanical connection in the design between the membrane in the water supply system and the valve installed in the gas pipe.
Gas will be supplied only when the pressure force of the water is sufficient to pressure the membrane. The principle here is very simple. If there is no water, then gas will not be supplied to the column burner. If you unscrew the tap and the water goes, the column will light up.
Common problems
Let's look at why the gas column goes out. Attenuation can be caused by a number of reasons. A sensor that detects a gas leak may turn on. There may be problems with the operation of the chimney. Clogging in the pilot light also often causes attenuation problems. Sometimes automation fails.
Often the problem of attenuation is associated with the quality of the fuel. Some gas facilities do not deliver pure gas, but diluted. Such low-quality fuel is easily determined by the orange color of the flame. If serious automatic protective systems are installed in the column, they will turn off the system.
It is also worth paying attention to gas leaks. Even light leaks are the reason why these units fail. Repair of geysers at home can help. But you should only turn to professionals - gas jokes are bad.
Weak or missing traction
Among the main reasons for this unsatisfactory performance may be weak draft, or its complete absence in the ventilation channel. 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 trip. If you open a window or door, and the column lights up and does not go out, in this case the reason is related to overheating.
Clogged chimney
If there are too many products of combustion accumulated in the chimney or if foreign objects are inside, then the protection system will be activated in the heater system, which will block the gas. Check for what reasons the geyser lights up and goes out in this case, as follows. It is necessary to open a window or window, light a match, and then attach it to the hole in the chimney. If there is no traction, the flame will not deflect.
To eliminate insufficient draft or its absence by cleaning the chimney and ventilation duct. In this matter, it is best to contact specialists who for a small amount will qualitatively clean the chimney.
Low battery
Another reason why the geyser goes out is because of the batteries. If the column is equipped with an automatic ignition system, and it is powered by batteries, then it is recommended to replace them. Also in this case, it will be useful to test the button responsible for starting and shutting down.
Water node problems
The next reason why the gas column goes out is the absence and weak pressure of water. When the pressure of its supply is insufficient when opening a tap with cold water, this is a problem for the supply companies. Because of this, the gas column goes out. What to do? You need to understand the causes of low pressure.
If cold water will be supplied with a higher pressure than hot, then such a column operation is connected with the water part of the unit. Among the reasons are clogged filters, deformation of the membrane. Often the reason is that the hot water supply pipe is clogged. If there are additional filters (if they are clogged), the water pressure can also significantly decrease.
How to troubleshoot
The first thing that experts recommend doing is to clean and rinse the filters. It is better to completely replace the cleaning elements with new ones. If the reason is related to the water part, you should call the utilities and find out from them why the pressure in the system is so weak. Often problems are solved by cleaning the pipes and the column itself. Membrane replacement may also be required. For questions on the gas part, it is better to use the service "repair of gas columns at home."
Professional craftsmen will carry out repairs as safely as possible.
The column lights up and goes out
These cases can be heard from the owners of this equipment quite often. You can fix the problem 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 an extinguished flame, but also to a 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 goes out. After all malfunctions are fixed, the gas unit, which makes life more comfortable, will work stably.
