In recent years, automatic gas water heaters are even much more common than semi-automatic ones. These are mainly Chinese gas water heaters of such brands as Oasis, Vektor, Ladogaz, Ariston and domestic gas water heaters Neva.

Let's identify the main typical malfunctions of gas water heaters and algorithms for establishing a specific problem of your gas water heater with our own hands. Consider all options for emerging problems:

Most likely, your gas water heater has simply run out of batteries. Therefore, with them, I recommend starting troubleshooting in an automatic gas water heater. You need to buy only fresh by date, alkaline batteries. Salt batteries are cheaper, but they also last much less. If the malfunction cannot be resolved in this way, then it is necessary to pay attention to the gaps between the ignition electrode and the gas column burner. Problems will arise if the gap is either too large or too small. With a large gap, there will generally be gaps in sparking, with a small gap, the spark will be weak, poorly igniting the gas mixture. In any of the cases, the gas will first accumulate in the gas column, then ignite untimely with a pop or even a tangible explosion.

2. You turn on the water, and the gas column is generally "silent" - there are no sounds. Piezo ignition does not work in this case.

First of all, we look between the water and gas block of the column in the area of the microswitch. It is more convenient to do this together. One opens the water, the other looks at what happens. When you open the water supply, you can see how the rod of the water block moves and releases the column microswitch button. There are two options:

Video (click to play).

- the stock does not move at all or barely moves. So the water block membrane is to blame. Most likely, the membrane is deformed, has micro cracks or even a hole. If such a defect is found, then you need to climb into the water block, first stock up on a membrane. Not the fact that it will be easy for you. The quality of the bolts and self-tapping screws of the Chinese speakers is, to put it mildly, poor, it is inconvenient to unscrew them without a certain skill. Sometimes it’s even easier to remove the column from the wall in order to do something .. And all the fasteners are often rusty. For those who decided to do it themselves, I advise you to read my article on disassembling a Chinese gas water heater Vector https://my.housecope.com/wp-content/uploads/ext/1003/poleznye-stati/remont-gazovoy-kolonki-vektor .html. If you really don't want to suffer, then leave a request to me;

- the rod walks quite briskly, releases the foot of the gas column microswitch, but that’s where it all ends, then there’s silence. No piezo sound is heard. The microswitch is most likely to blame. It's easy to check. The microswitch connector is removed, and the contacts are closed directly in the connector. If the crack goes, then the reason is the mikrik. If there is no cracking at the same time, then you need to look at the thrust sensor, overheating sensor, the column ignition unit itself.

Usually, dead batteries are to blame. There is enough energy for a spark, but the coil on the gas valve is no longer pulled in. The gas valve emits a characteristic click when opened. If you hear a piezo crackle, but do not hear the valve click, then gas does not flow to the burner precisely because of the valve. Either it is faulty (which is rare), or the column batteries do not have enough energy to open the valve.

A very unpleasant and terrible breakdown, which can lead to both failure of the water block and injury to the one who uses this column. If this happened repeatedly, then the gas column must be stopped using.Most likely, the reason lies in the water block (the stem is jammed, the plate has collapsed, or something else).

The reason lies in the ignition electrode. It either oxidized and became covered with a layer of soot (clean it), or it does not warm up well with the burner flame, and the column "does not see" that the gas is on and shuts off the gas supply to the burner.

There are several options. The most easily eliminated breakdowns of traction or overheating sensors. A less successful arrangement if the radiator of the gas water heater burns out (and this is almost the cost of the entire column as a whole), or the absence of draft in the chimney. Some have not encountered this, and those who have encountered it will agree that the problem is unpleasant. Usually, if there is no draft in the chimney, then it is not always removable by the employees of public utilities. The problem is sometimes not permanent, but appears when there is a strong wind outside, frost or, conversely, heat.

I described typical malfunctions and methods of finding them. I see no reason to consider faults such as water leaks. They are visible and easy to define. If you have any questions for me, you can call or email me.

This article is useful for clarifying the causes of a speaker malfunction. You can carry out minor repairs yourself, but for more serious ones (although you understand the cause of the breakdown), I would advise you to call a master. The gas master has the skills and experience of repair, knows where to get spare parts or he has them.

I am ready to help you personally if you call or place an order at the bottom of the article. You can just call for a consultation. It's free.

Let's say right away that repairing a gas water heater, like any other gas equipment, is a matter exclusively for professionals. But, although repairing speakers with your own hands is not allowed, knowledge is not superfluous. The ability to determine on your own what exactly has broken down, how this breakdown threatens, and what the repair can be will not interfere with anyone. What breakdowns of gas water heaters are there, and what "symptoms" are they accompanied by?

At first glance, repairs may seem difficult

To begin with, before getting acquainted with the basics of troubleshooting, it is not out of place to find out how the gas water heater is arranged, the repair will largely depend on the device. We will not delve into the intricacies of the device of many speaker models, we will limit ourselves only to acquaintance with the general principles.

Centralized hot water supply appeared relatively recently by historical standards. The issue of heating water at home was solved in various ways, but the most common one we had was a storage solid fuel heater - the so-called titanium. Titanium was fired with coal, less often with wood or fuel oil. The water in the boiler had to be warmed up in advance. So taking a bath had to spend at least an hour. Of course, using such a device was very inconvenient. The problem of fast heating of water was solved in gas water heaters.

Gas water heater device

The work of the geyser consists in heating tap water with gas from the city main. To speed up the heating process, a heat exchanger serves, in which the water flow is distributed through a system of thin tubes located directly above the gas burner. Due to this, it is possible to heat the water quickly enough, right in the process of use, there is no need to pre-accumulate the heated water in the tank.

This is the fundamental device of the gas water heater, all the rest of the filling serves to ignite the gas, regulate the heating of the water, and also ensure safety.

The main burner is ignited:

From the igniter. The constantly burning igniter, in turn, is turned on by piezo ignition (automatic or manual from a button) or manually ignited from a match. Unless, of course, you are lucky enough to get ownership of such a rarity.
Piezo ignition without igniter.
Electronic ignition. By its structure, electronic ignition is similar to the ignition of a car.

Security systems are:

Mechanical. Almost any column, even stuffed with electronics, is equipped with a simple device - a mechanical connection between a membrane in a water intake device and a valve in a gas pipe. The gas valve only opens when the water pressure pushes against the diaphragm with sufficient force. The principle is simple: no water - no gas is supplied to the burner, turn on the water - the burner turns on.

The column may not work for many reasons. Now we will tell you about the most common ones.

There may be several reasons why the gas column does not light up. First of all, make sure the pilot is on. If the igniter does not work, call the gasman from the public service, he will replace or clean the igniter jet.

In columns with electronic ignition, if ignition has not occurred, the gas supply is cut off by a valve, which the user is informed about by the corresponding indicator. Study the instructions (which you should have studied before turning on the column for the first time), perhaps the problem can be solved with your own hands by simply replacing the battery. Otherwise, contact the manufacturer.

Another reason that the gas column does not ignite may be the lack of draft in the ventilation shaft. You can check the draft by holding a sheet of paper or a lighted match to the ventilation grill. If there is no draft, you can eliminate the blockage of the ventilation well with your own hands, or by contacting the utilities.

Warm water will not give a lighted column

Another reason for burner failure is deterioration of the water diaphragm. The membrane deforms over time from constant loads, the burner switching device loses sensitivity when water is supplied and does not work. Unfortunately, nothing can be done about this, even in the columns of serious Western manufacturers, the membranes have to be changed every 5-7 years.

Try to open the water tap to the maximum, if the column is turned on at maximum pressure, then it is the membrane that will have to be replaced. It is also necessary to check the filter that is equipped with the water intake of the column. Insufficient water pressure to open the gas valve may be due to a clogged filter. The water filter does not belong to gas equipment, and you can replace it yourself.

Finally, the column may not light up due to improper operation of the bimetallic sensors. They will be discussed below.If the column ignites but goes out, the culprit is most likely a bimetallic temperature sensor designed to protect the column from overheating. A malfunction usually has two manifestations:

The burner lights up, the column works normally for a while, after which it goes out and does not work for some time - attempts to ignite the results do not give results. After 15-20 minutes, the column can be turned on again, the burner lights up, and then again, after about the same period of time, it goes out again. This happens due to the "innate" increased sensitivity of the sensor.

It also happens that the column goes out at the most inopportune momentIn principle, this is a warranty case, but the fact is that the problem is seasonal in nature and arises during the heat of summer or winter, when the windows in the kitchen are constantly closed. In both cases, the air temperature is elevated and the column is not cooled properly. It may happen that the problem will manifest itself when the repair period has expired. Alas, in this case, the repair will have to be done at your own expense.

Disconnections of the column are chaotic, the device sometimes does not light up at all. Such behavior of the heater may indicate deterioration of the insulation of the sensor conductor. A short to the body occurs, causing the safety valve to operate. It is useless to call the gasman - the problem is not in the gas part, you should also not try to fix it with your own hands.For repairs, it is better to contact the manufacturer of this model or to the service center.

If the gas supply occurs, it means that the water pressure in the water intake is normal, the problem is in the blockage of the heat exchanger with scale. One of the reasons may be "idle" combustion of the igniter for a long time. The igniter has enough time to heat the heat exchanger, causing active evaporation of the remaining water. The formed scale is not washed out due to the lack of water flow and until the next turn-on of the column has time to "grab", the result - the column does not work. Repair consists in cleaning or replacing the heat exchanger.Scale-clogged heat exchanger Reduce water pressurePossible reasons are as follows:

The gas pressure is too high, the burner ignites too actively, as a result of which the flame breaks out.
The gas pressure is too weak, air gets inside the burner, which is accompanied by a microexplosion.

The burner needs cleaning and adjustment. In principle, nothing complicated, but you do not need to take on this work with your own hands, the repair of the gas water heater should be carried out by a specialist.Insufficient heating of water can be associated with a low power of the column. Do not turn on the hot tap in the bathtub, sink and kitchen at the same time, or buy a more powerful unit.An incorrectly selected column will not have time to heat the waterAnother possible cause could be a clogged burner, as indicated by a yellow flame. Call a gasman, a specialist will solve this problem in an hour.This is already serious and threatens with the most dire consequences. Turn off the column immediately, turn off the gas supply valve, provide constant ventilation in the room, call the emergency service (104) and wait for the arrival of the brigade.In conclusion, once again I would like to remind you of security. Do not try to disassemble, clean or repair gas equipment yourself. This is a job for qualified professionals only.Despite the widest range of electrical heating appliances on the market, the gas water heater is still one of the most popular means of heating a house and providing it with hot water. This is a fairly economical option, since it allows you to simultaneously provide several drainage points in the house. Another advantage of gas water heaters can be considered the fact that they allow you to use hot water, practically unlimited, without any restrictions.

The first of them is designed for gas supply, the second - for cold water supply. In addition, a pair of burners is located at the bottom, one auxiliary and one main.Important! The device of the gas column can be different, depending on the method of ignition - it (ignition) can be electronic, manual and using a piezoelectric element. Image - Column Ladogaz DIY repair

Such devices are designed to provide domestic and industrial facilities with hot water. The essence of their work is quite simple: cold water from the pipeline enters the column heat exchanger, where it is heated by burners (they are located under the heat exchanger). As you know, fire needs oxygen, therefore, so that the burners do not go out, the column is connected to the ventilation system of the house / apartment. The exhaust gas is eliminated by means of a special chimney, which is combined exclusively with a gas water heater.

All the described types of columns function somewhat differently.

So, if the device is turned on manually, that is, the gas has to be ignited with matches, the burner will ignite from the fact that you turn the fuel supply valve. Although it is worth noting that such designs have become outdated a long time ago. Modern designs are equipped with either an electronic ignition or a piezoelectric element.

New models are activated at the touch of a button located on the front panel of the device. Piezo ignition creates a spark that ignites the pilot. In the future, everything happens in automatic mode - the tap opens, the column lights up, hot water begins to flow.

If the gas water heater is fired up electronically, then it is perhaps the most reliable and durable device. The system is turned on by means of a pair of batteries supplying the charge necessary for the formation of a spark. No buttons, no matches, the only thing you need to do to turn it on is to turn on the tap. In most cases, batteries last a very long time because the energy required to charge is minimal.

The use of gas water heaters, however, like any other equipment, is accompanied by malfunctions, frequent or rare. At the same time, there are such malfunctions that can only be eliminated by specialists who have the necessary knowledge and admission for this. But there are those that can be easily eliminated with your own hands, so we will consider them.

Video - sensor malfunction

If the internal elements of the device are covered with soot or dirt, then this can also lead to failure. To solve this problem, you must remove the outer casing of the device, then clean each of the elements using a vacuum cleaner.

The next sign that the gas column has stopped working correctly may be the burner decay immediately after switching on. This happens due to the fact that the ventilation channel is clogged. Modern models of gas water heaters are equipped in such a case with special sensors that will inform the owner if there is no traction. After that, immediately turn off the gas supply. Next, the chimney should be checked. For this, the plug is dismantled and everything that has accumulated there is removed.

Important! You can check the draft of the chimney in the old "old-fashioned" way: bring a lighted match to it. If the fire on the match deflects in the direction of the chimney, then everything is in order with it. If this did not happen, then he needs a complete cleaning.

It is for this reason that the gas water heater should be inspected annually - this is the only way it will work correctly.

We also advise you to familiarize yourself with the basic requirements.

Modern gas water heaters are small and compact, so they can be placed in almost any convenient place. Their service life depends largely on how correctly they are installed and used in the future.

As you know, the device of the gas water heater is such that it has to work with a rather dangerous fuel. For this reason, during installation, make sure that, God forbid, there is no gas leak. If you cannot, for one reason or another, take care of this, or, even worse, cannot eliminate all the leaks, then further operation will turn into a dangerous activity, which sooner or later can lead to an explosion.

For this reason, it is categorically not recommended to install a gas water heater with your own hands. It is better to have professionals who have all the necessary skills, experience, and the appropriate equipment to do this.

So, for installation, you need the following tools:

dowels;
magnet and salt filter;
drill;
the required number of taps;
pipeline;
chimney corrugation;
gas pipe;
Mayevsky valve;
actually, the column itself.

The device is installed only in the kitchen and only on the wall, which is made of refractory material. The distance from the column to the wall surface should be at least 2 centimeters, if it turns out more, then this is even better. An asbestos sheet should also be laid here, which must have a minimum thickness of 0.3 centimeters.

Important! The apartment / house must have a chimney that will remove the products of gas combustion. It will consist not only of vertical, but also of horizontal sections, and on them it should go at a slope (approximately 0.2 centimeters per each running meter).

So that the pipeline does not accidentally burst, the gas column should be installed only when the water is completely drained from the system.

But editing, as we have already said, is not the most important thing. It is also important that the device is used correctly, for which certain operating rules must be followed. If you do not do this, then even the most expensive and high-quality model will soon break down. So we want to prevent this from happening. Firstly, we must not heat the water to a temperature that would exceed 60 degrees. The fact is that too high a temperature will lead to the formation of salt scale on the walls of the heat exchanger. The result is more frequent cleaning or, even worse, replacement of the heat exchanger.

In addition, we can damage the structure of the heat exchanger by using too hard water. To avoid this, the water should be softened using special means, or a special filter should be installed in the system.

Finally, it is not recommended to dismantle and clean the gas water heater with your own hands, because, as we have already said about this, professionals should deal with this procedure. Doing this with your own hands is extremely dangerous.

If you decide to purchase a geyser device for yourself, then pay attention, first of all, to the power of the model you have chosen. It should be enough to provide all your family members with hot water. The power of almost all modern models fits into the range from 3 to 60 kilowatts.

Important! The more powerful the gas water heater, the more water it will be able to heat up within a certain period of time.

The average “cell of society”, consisting of four people, needs a device with an average capacity of 16-24 kilowatts. It is more than enough for the dishes to be washed and everyone was able to take a shower. Even if the device has a low power of 16 kilowatts, it will be able to give 10 liters of hot water, which is enough to be able to wash and wash dishes at the same time.Of course, if you can, then buy a column with a capacity of 24 kilowatts, since it can provide 24 liters of heated water.

In addition, it is advisable to take into account the water temperature that a specific model can provide. For its designation, the Latin letters DT are used. For example, if water is already supplied to the heat exchanger at a temperature of 12 degrees, then it will heat up to 24 in it. therefore, it can be used even without preliminary dilution.

Today there are models that are capable of heating water even up to 50 degrees. Their power, as well as the cost, is an order of magnitude higher than conventional models. For this reason, if several plumbing elements are simultaneously connected to the system at once, then it is better to purchase a more powerful column so that it can provide them all with hot water at the same time.

Also, when buying a gas water heater, see if it is equipped with safety sensors. They are of the following types:

overheating;
damping of the burner;
burning;
reduced pressure;
temperature;
sudden interruption of water supply.

And remember: gas water heaters are only allowed to be installed in the kitchen! Installation of a gas water heater in the bathroom is prohibited! Unless she (the bathroom) meets all existing requirements.

So, we have analyzed what a gas water heater is, what are its features, what malfunctions may arise during operation and how to fix them later. We only note that such devices are extremely economical, especially in light of the ever-increasing utility rates. And the last thing: do not forget that prophylaxis of the column's performance should be carried out annually.

I wrapped the microswitch, which is under the flow sensor rod, in plastic wrap and now it is not afraid of leakage. And my leakage is so small that I couldn't see the drop nirazu, and the dampness still limescale the microswitch button, so that it did not come out of it and did not turn on the electronics. The microswitch can be easily removed from the bracket with two small screws.

I have a problem with a Selena gas water heater. As soon as the lid in the battery compartment is closed, the gas immediately ignites even when the water is closed. To heat the water, I first open the tap with water, then close the battery compartment lid. To turn off the gas in the column, I open the battery compartment cover. I called the master, changed the microswitch, but it did not help. The foreman cannot determine the breakdown. Who knows how to fix it, leave a comment, please.

Such a complex device as a gas water heater serves for quite a long time, care and operation is carried out according to the instructions attached to this unit.But all things deteriorate and sometimes minor or major repairs of gas water heaters or their prevention are necessary. As well as replacing some of the components of the gas column.

The internal structure of flow-through gas water heaters is of the same type and almost does not differ from different manufacturers. The main difference may be in additional options (display, automatic gas ignition, second temperature sensor, etc.), in the appearance of the device or in the design.

This is a gas column heat exchanger, it may look different from different manufacturers, but the principle of operation is the same.

A heat exchanger is installed inside - a finned copper tube through which a water flow moves. The burner standing under the heat exchanger heats up the tube and the water passing inside it heats up. With a low water pressure or its absence, the incoming flow is blocked by a valve (curtain), to which a spark ignition switch is attached. This is for fire safety.

To repair a faulty gas water heater or prevent a gas leak (if you smell), you need to call a gas water heater repairman. But if you decide to call the workers of Gorgaz, then do not think that they will immediately come, sometimes they refuse to come, explaining that the repair should be carried out by the company (or store) that installed the gas water heater.

Now a lot of "left" firms have divorced. and calling the workers of such organizations to their homes brings a number of other problems. Many craftsmen, seeing your incompetence in this area, find non-existent faults in the gas column or deliberately raise prices.

To increase the safety of the population, it is prescribed that malfunctions associated with gas equipment be eliminated by employees of the relevant service. But there are some problems that you can fix yourself. If you know how to hold the tool in your hands, you can repair the gas water heater with your own hands.

It is not very difficult if you know the typical problems of these water heaters. Below we will tell you about the most common of them and show you how to fix this or that breakdown. And let's start by setting up the unit.

Adjusting the height of the burner flame - the closer to the maximum the hot water is.
Adjusting the water flow - the closer to the maximum, the greater the flow, therefore, the water is colder.
Winter / Summer - the mode of using the speaker at different times of the year. In winter, the power is greater than in summer.

Not all masters know how to properly set up a gas water heater and simply don’t do it, leaving it as it is (by default). But we do not recommend leaving the factory settings and making adjustments yourself.

Set the gas and water knob on the heater to minimum.
Open the gas and water supply valves on the pipelines.
Open a hot water tap and adjust the water pressure you need using the knob on the gas water heater.
Wait 1-2 minutes and measure the temperature. Use the gas knob on the column to increase the flame, thereby increasing the temperature of the water to the one you need.
When the water temperature is comfortable, you can leave all adjustments alone and use the water.

In the future, you can adjust the temperature with another knob (supply of heated water).

This is a membrane in the gas column, if it fails, then the unit stops responding to the pressure of water.

When adjusting the speaker, sometimes unpleasant moments arise. The new column either turns on at a very low pressure, or does not want to start at all. It depends on the increased or decreased water pressure in the pipeline and is eliminated in the following ways.

With our water quality, the heat exchangers in the gas columns are clogged with scale quite quickly and very much, which reduces their thermal conductivity and increases gas consumption.

The longest, in time, process - cleaning the main tube (radiator) from deposits arising from heating tap water.If you turn the gas knob all the way, and the outgoing water is barely warm, then this indicates that the heat exchanger is clogged with ordinary scale, which does not transfer heat well.

This happens quite often in the case of a gas water heater without auto-ignition (with an igniter). Scale also forms if you set the water heating temperature too high. The unit overheats, the tube (radiator) heats up to 80-850, which contributes to the rapid (a little over an hour) the appearance of scale. Isn't it better to just turn off the speaker in time? Then there will be no problems, because 40-600 are enough for all washing and washing processes.

Check the inlet cock or valve before starting work on the heat exchanger. Maybe the whole reason is their clogging. But if they are in good condition, it is necessary to get rid of the deposits in the tube.

There are two ways to deal with the scale problem. We'll look at both options.

The Cillit KalkEx cleaning system does its job pretty well. With its help, you can quickly clean any boilers from scale. Unfortunately, it is not very accessible for ordinary users of gas water heaters.

This is an expensive method using a special device. (Cillit KalkEx) and a set of special preparations for flushing. Your speaker does not even need to be removed from the wall. You just need to disconnect the water hoses (inlet / outlet).

The purification device is connected to the column, and it runs the heated reagents in a closed loop (in a circle). Scale under their action decomposes, is washed out and drained.

Cheap but time consuming and laborious process... For its implementation, it is necessary to disassemble the water heater almost completely and then rinse it manually.

The following materials and tools will help us with this:

open-end wrenches (set);
screwdrivers (Phillips and regular);
paronite gaskets (set);
rubber hose;
vinegar essence or anti-scale agent.

To remove the heat exchanger, proceed as follows:

first, we block the access of cold water;
then we remove the external elements that prevent disassembly (knobs of switches, regulators);
remove the casing, and for this we unscrew the screws located on the rear wall of the unit, lift and remove the cover;
we open the "hot" tap;
unscrew the supply pipe from the heat exchanger and move it aside;

After the water has completely disappeared, we put the hose on the heat exchanger tube and raise it above the column level. Slowly, pour the solution prepared by us into the hose and leave the column for 4-6 hours.

Next, you need to slightly open the water supply tap and watch the water that will come out of the column, if you saw a lot of scale, then our work was not in vain - we got rid of it... If there is no scale in the outgoing water, then we repeat the whole process again.

The failure of a water heater can occur for many reasons. We will list the most likely ones:
The simplest reason for this trouble is the lack of normal draft in the chimney. If the chimney is clogged and there is no "draft" in it, then the column may not ignite.
To check for a malfunction, you can bring a piece of newspaper, a napkin or a lighted match to the chimney. If they flutter, then the cravings are in order. Otherwise, you will need to clean the chimney.
If the device (only in units with auto-ignition from batteries or an electrical network) does not ignite, then it is all the fault of the discharge of the batteries or the malfunction of the wires, the igniter unit. Eliminated by inserting batteries or checking the electric ignition system.

Failure of the igniter system can occur from poor pressure water. Open any tap with cold water and check the pressure, if it is weak, you can call the ZhEK and find out what the problem is.

If the column does not ignite when water is supplied or only turns on at a very high pressure, then the problem is most likely in the membrane, which, due to wear, reacts poorly to the water passing through it.In this case, it must be replaced.

This is a temperature sensor that measures the temperature of the gas column during operation, preventing it from overheating.

A temperature sensor is installed on each gas column, which makes sure that the column does not overheat in the event of a failure the column may turn off spontaneously during operation... It usually looks like this:

After normal operation, for some time, the heater “stalls” for 20 minutes. After this time, it can be turned on for the same period of time. The malfunction, as a rule, is seasonal and appears only in summer or winter with closed windows.

The device turns off when it wants and then does not light up... This can happen when the sensor wire is shorted to the body. Check wires are intact and well insulated.

In order to check the sensor itself for operability, two contacts should be removed from it and short-circuited with a needle, a paper clip, a piece of tin. If the gas appliance turns on and works, the sensor must be changed.

If you see similar spots on your column, then be sure that it is leaking and needs repair.

This malfunction can occur mainly in gas water heaters that have been operating for a long time. The two main reasons for the leak are:

Tubes (bends) or gaskets in the joints are cracked.
Replacing a radiator or taps is quite expensive. Therefore, there is a reason to repair the gas column on your own. For repairs you need:

screwdrivers (cross and regular);
open-end wrenches (set);
solder with rosin;
a vacuum cleaner;
solvent;
"Skin".

Due to the harsh operating conditions, the radiator or bends can burn out and holes appear on them. If you have determined where the leak is, then you can repair the small hole with an ordinary soldering iron.

Preparing the gas water heater for repair

Drain all liquid from the system - open only the hot water tap, unscrew the nut on the cold water inlet pipe, and most of the water will flow out;
Remove the radiator completely;
Examine the entire tube. - if you see "greenery" - clean and inspect these places for cracks.

Soldering a heat exchanger does not always give good results, here a lot depends on your skill. If the soldering is poor, the heat exchanger will quickly flow again.

When you have found the leaks, you need to do the following:

clean the holes found with "sandpaper" and immediately wipe it with a cloth and solvent (this will remove the remaining grease, carbon deposits and dirt);
using rosin with solder, tin this place with a 100 watt iron (in the absence of rosin, use aspirin);
rub the crack or hole with solder, and after it cools down, add more tin (the layer should be 1-2 mm).

Replacing flexible hoses of this type does not require special skills; anyone can do it with a wrench.

Very often, leaks are formed in the places where the outlets are connected to the heater from the outside or to the internal assemblies of the column. All connections are made by "American" with gaskets inside.

Due to constant heating / cooling, the rubberized liners either melt or lose their properties and harden. Cracks appear in them, along which water flows.
If you notice a gas column leak in such connections, then replace the gaskets. Using a wrench (mostly 24), unscrew the nut and replace.

It also happens that the flanges on the pipes crack over time - in this case, you need to replace the entire pipes.

Be sure to change the batteries in the gas water heater in time, because if they are dead, your column will start to emit pops when it is turned on. Also, due to dead batteries, the column may turn off spontaneously.

These startup and operating sounds indicate the following:

a little air got into the system (into the burner) due to the low gas pressure, which generated a microexplosion;
the flame breaks down due to the high pressure of the gas;
nozzle blockage;
low draft of ventilation;
the batteries are dead.

On your own, you can only eliminate the malfunctions described in the last two points.

This can happen for several reasons.

The simplest reason is incorrectly selected gas water heater... You have saved money and bought a low power heater that is unable to meet your hot water needs.
The second reason is the low gas pressure in the pipes (in the apartment). Call gas workers to check the system.
The third reason is the usual blockage (jet, filters, scale, hoses, etc.), some types of which are described above. You can check this by the color of the fire, which changes from time to time. This is evidenced by the presence of soot.

You can only adjust the temperature and clean the column yourself.
