The Junkers company existed until 1932. From that moment on, the company was purchased by Bosch Gruppe, which, however, did not affect the name of the water heaters produced by the division of the main office.
Junkers flow-through geysers are available in several modifications, differing in the principle of ignition, as well as the type of combustion chamber. Flow-through boilers operating using a pilot burner are popular among domestic consumers. Average term The service life of the Junkers column exceeds 15 years.
Junkers speaker design
The Junkers brand is considered synonymous with quality and reliability throughout the world. The speakers are distinguished by a well-thought-out internal structure and design. The following types of water heaters are offered to domestic consumers:- Semi-automatic- the company began producing speakers back in 1968. During operation, a pilot burner is used. Ignition is carried out using a piezoelectric element. The main burner turns on when the DHW tap is opened.
- Automatic - powered by batteries or a hydrogenerator. The series features simple Junkers geysers with open camera combustion and multifunctional models with modulated power. The performance of the burner varies depending on the water pressure.
In the internal structure of gas flow systems speakers Junkers are used exclusively quality materials. All water heaters undergo mandatory testing and are subject to certification.

How to light a Junkers gas water heater
Overwhelmingly water heating columns Junkers offered to domestic buyers operate in semi-automatic mode. Semi-automatic ignition gas boiler done like this:- on the front panel of the water heater there is a valve that opens the gas supply;
- the button is pressed and the wick is lit using a piezoelectric element;
- gas valve leave it clamped for another 20-30 seconds;
- Now the button is released, the flame on the burner should continue to burn.
How to clean a Junkers column with your own hands
Any renovation work gas consuming equipment must be carried out by a specialist who has the appropriate work permit. Cleaning the pilot burner and heat exchanger is a job that you must not do yourself. Maintenance is carried out at your own risk.To clean your Junkers speaker at home you will need to do the following:
- turn off the gas and water supply;
- remove the casing;
- disconnect the smoke receiver and water unit;
- pull out the heat exchanger.
Repairing Junkers geysers with your own hands leads to the manufacturer’s refusal to warranty service equipment.
Junkers speakers - malfunctions and methods for eliminating them

Today, many residential premises continue to use gas water heaters. Speakers are a great way to use hot water, if the apartment or house has gas and water supply. Very often in apartments hot water is turned off for the entire summer period. Everyone tries to make their life more comfortable through their efforts. For many, installing a gas water heater is the only solution. How to turn it on correctly geyser, you can read in this article.
Many consumers are confident that using geysers at home is life-threatening, as a gas leak may occur or the water heater may explode. Previously, old-style speakers were installed in homes, which could fail if the owners ignored safety precautions when using them. Modern geysers are the new kind devices with automatic protection.
If the column fails for one reason or another, then automatic protection makes it so that the gas stops flowing.
You should not use outdated models of geysers - they require an extremely careful and careful approach, which will make its use extremely inconvenient. In order to ignite an old-style column, you must use manual ignition. Modern devices in most cases they turn on and work automatically.
Methods for turning on units:
- Manual ignition. It is mainly suitable for igniting older models. Earlier to light the column. It was necessary to use matches to light the wick. First, it was necessary to open the water supply, which was connected to the column. Then open the main valve, and then make sure that gas is supplied to the ignition wick. The pilot wick continued to burn even in the absence of water pressure. The speaker had to be turned off manually. At home, using speakers of this type is not advisable.
- Piezo ignition. In many types of speakers this element is installed. When you press the button, the wick in the combustion chamber ignites. The ignition wick ignites due to the mechanical force causing a spark. To turn on the main burner, you must turn on working condition the main regulator that supplies gas.
- Automation. Modern modifications involve automatic ignition of the wick and main burner. The turbine is responsible for this; it turns on due to the water pressure. The only problem with the operation of such a column may be insufficient water pressure.
When installing modern speakers, you can be sure that they are safe to use. In order to use them you do not need special knowledge and skills. But if the column breaks down, you need to contact the gas service directly. Self-repair It is strictly forbidden to practice columns.
A simple ignition method: how to turn on a Bosch gas water heater
Using modern geysers usually does not cause difficulties. When purchasing speakers, you should pay attention to the presence of a passport and warranty for the product. It is also very important that the seller provides instructions for its use along with the speaker.
The instructions for using a modern Bosch gas water heater say that it must be put into operation by the craftsmen who installed the water heater.
How to light up a Bosch speaker:
- Move the control to the right if it is in the “Off” position.
- The regulator should move to the “Piezo ignition” position. This means the spark icon and vertical buttons will connect.
- The start button should be pressed down with your finger while pressing the piezo power button. The fact that the piezoelectric element has triggered will be indicated by characteristic clicks.
- It is important to ensure that the flame does not go out for the first ten seconds. Then you can transfer the power to the desired level.
After the power is switched to the desired value, the flame constantly burns in the mode that was set. But when you turn on the hot water, the column starts automatically heating the water. It’s easy to turn off the column – you just need to move the slider all the way.
Open type: how to start a gas water heater
Flow-through geysers installed in residential premises cause a lot of controversy. It should be noted that modern geysers do not pose a danger if you follow all the rules for their use. Everyone who lives in an apartment or house and uses such a column to heat water should know the rules for handling a water heater.
If the smell of gas appears in the room while the speaker is operating, the device must be turned off immediately.
If there is a large accumulation of gas in the room, it is necessary to open the windows to reduce the gas concentration. It is important to know that if there is gas in the room, turning on electrical appliances and fire is strictly prohibited. If the water heater is not working properly, you should call the gas service.
How to light an open type column:
- It is strictly forbidden to light a fire if there is no backdraft in the chimney.
- Do not turn on the device without understanding the instructions.
- It is important that the room is equipped with a constant flow of air.
- You cannot repair or make changes to the operation of the gas water heater yourself.
When lighting, do not touch the front of the panel. When turning on the speaker, it is better to set it to low power. It should be noted that modern models The dispensers are equipped with safety devices that stop the dispenser from operating if there is no traction.
Ignition features: how to turn on the Ariston column
A geyser is a typical analogue of a water heater. The water is instantly heated using a flow-through water heater. The column allows you to use hot water constantly.
The type of ignition of modern geysers, although considered simple, raises many questions for many users after direct installation.
It is very simple to ignite the Ariston column, since it can have piezo and electronic ignition, which requires the user to simply open the tap. The device needs to be turned on only after it is installed. After this, the column will work smoothly.
Features of Ariston speakers:
- Compactness;
- Stylish and compact design;
- Available in different colors;
- Automated.
Interestingly, many modern geysers can be powered by batteries. When choosing a column, you need to pay attention to its ignition methods and installation options. In any case, for safety reasons, the old gas water heater should be replaced with a new and modern one.
Instructions: how to turn on the gas water heater (video)
Today many people use gas water heaters. They ensure the availability of hot water even when it is turned off. But many consumers have a preconception that geysers pose a great danger. Modern geysers debunk this myth. If you ignite the column correctly, it will work properly and completely safely. Good reviews Vaillant, Junkers, Bosch, Ariston gas water heaters are used.
Answers from users on repairing the Junkers geyser
Question: I have a Junkers WR-10 gas water heater installed and it takes a very long time to tinker with its ignition. Piezo ignition. At first you have to hold the button for a long time (about a minute). Then the piezo igniter somehow does not ignite it (rarely). Well, it doesn’t bother me anymore - we’re used to it. We light it with a match - after holding the button for a minute and a half (apparently so that the gas accumulates). Then, when the wick is still lit, hold the button for about a minute and only then move it to the right. Tell me what could be wrong. It's very difficult to light it.
Answer: The reason is simple - gas comes out of the tube. Therefore, until the tube is filled with gas, the wick does not burn (described in the manual). This column should operate in standby mode on wick. If you're worried about the wick constantly burning, buy an automatic one.
Question: The wick lights up, I keep it in this position for 5 minutes, switch it to working condition, it goes out. Gas water heater Junkers Bosch semi-automatic! Why is this so, what should I do?
Answer: I had the same problem. I removed the housing, disconnected the tube through which gas is supplied to the wick, and blew it out with a pump from the bicycle. put it back - everything works! as one speaker repairman explained to me, this needs to be done once a year, especially after the summer, when the windows are open and dust, etc. gets clogged up in this tube.
Question: We installed and started up a Junkers gas water heater and the problem is constant in winter. There is also not enough gas, and besides, the gas that is often supplied is not pure. But it’s European, they don’t understand what red gas is instead of blue.
Answer: on your column at the bottom there is a screw under the seal (blue plastic). You remove it and, with the burner on, turn it counterclockwise within reason (you will see it by the flame). You'll be back for the summer. If this doesn't help, the pressure may actually be low.
Question: I use a Junkers WR-275 gas water heater in my house. Over the course of 10 years, two columns of the specified company and brand failed. I didn’t clean the first one at all - it worked for 5 years and the heat exchanger leaked. The repair resolved the issue for 3 months and a new one was purchased. The installer said that the whole problem was that he did not do maintenance (cleaning). So I cleaned the new one. Result: I worked for 4 years. The reason for the failure is the same - the heat exchanger. Why is this happening?
Answer: You simply have a problem with water quality. Because of this, heat exchangers fly.
Question: after the column has been running for 2-3 minutes, it turns off completely, after which the wick can only be lit with matches. Does anyone know what to do with Junkers?
Answer: There was such a problem, they changed the water overheating sensor. Everything works well.
Question: The Junkers burner worked for 7 years. The igniter does not work. and if you light it with matches, the wick goes out when moved to the working position. what can you recommend?
Answer: I have the same problem. The technician said that the thermocouple had burned out.
Question: Column Bosch Junkers WR-13-2. Installed two years ago. From the very beginning there were problems. The first time I couldn’t light it for about half an hour. Something was stuck there and the column did not want to light up. Then something clicked and it seemed to start working. And so it worked for two years, igniting every other time. And now I’m starting to get really weird. The display shows a temperature of 40 degrees, and the water flows a little warm. You increase the temperature with your hands to normal to wash, and the display shows 62 degrees!
Answer: The thermometer there has no connection with the gas supply and burner power. It's just a thermometer. Well, this what’s-its-name generator. With our water and its pressure, this is often a useless device. And sometimes it works, but there is not enough power, especially during ignition, since at this time the maximum current is consumed. Treatment - transfer to batteries.
Checked, the symptoms are exactly the same - ignition every other time, puffing, etc. since the spark is weak and cannot ignite the burner. At a minimum - for starters - connect the power from two new R20 alkaline batteries in parallel (without mixing up the polarity, red is positive, and the connection should be 1.5V, not 3). Regarding the thermometer - if it is lying too much - most likely the temperature sensor has gone sour, replace it.
Question: please tell me the electronic unit for Junkers gas water heaters, why might it fail? Explanations from the service technician due to power surges in the network. I somehow don’t understand, the speaker is not connected to the network. Who has encountered this?
Answer: We will try to help you. The house is equipped with a Junkers WR-10 B gas water heater. The water heater did not work for even a year and suffered its first failure - the burner stopped turning on (but the igniter did light up). Reason - breakdown field effect transistor Q2 in the electronic control unit (without it, the circuit does not sense the burning igniter and does not want to open the burner valve).
I replaced the broken transistor with a KP303V (KP303B should also work). It turned out great, but a month later it was rejected again. I replaced the transistor again, but it barely lasted a couple of months. Having replaced the transistor (Q2) for the third time, I bypassed its gate circuit with a varistor of type 390KD07 (39V), i.e. added a new component to the circuit. Such protection turned out to be sufficient - the column gained new life and 3 years only makes me happy!
Question: A Junkers WR-13-P gas water heater with piezo ignition is connected. We bought it in January 2008, that is, it is not even a year old. It worked without any complaints. We were very pleased. This afternoon the column simply turned off (the flame went out). Trying to light it again was unsuccessful; I can’t even light the igniter. I checked the hood and everything was fine (I thought the hood control sensor was cutting off gas), the gas pressure was also normal. The question is: What could be the matter? Has anyone encountered such a problem?
Answer: Try cleaning the igniter. Perhaps you need to check all contacts: on the thermocouple, overheat sensor.
Question: Gas. Column Junkers WR 13-P, installed about 4 years ago, used little, sometimes did not turn on for several months (due to departures), a year ago, began to go out periodically, then did not light up at all (when you release the button, the igniter goes out), they called a technician from the service center, he came and ran sandpaper over the thermocouple several times - everything worked. Three minutes, and not such a cheap call. Six months later, the same story again, the igniter goes out as soon as I release the button, I, like a master, periodically cleaned the thermocouple with fine sandpaper, at the very least it worked.
But now nothing helps, the igniter tube is clean, the heater is not clogged (the pressure is normal), the overheating and draft sensors seem to be normal, there is draft. Apparently the problem is in the thermocouple, I called to find out about the money and the work, the cost is half a new column. A little expensive. Does it make sense to change or buy a new one? Is it generally possible to somehow directly short-circuit, bypassing the thermocouple, or install a thermocouple from another, cheaper brand?
Answer: Maybe my experience will be useful. Symptoms: The igniter does not light, if you manage to miraculously ignite the igniter, then the gas water heater works for a short time until the hot water is turned off for the first time (the igniter goes out again). One of the reasons: The igniter flame does not reach the thermocouple or reaches it, but is unstable. The igniter in a Junkers gas water heater is usually secured with two clamps. Over time, for one reason or another, the igniter tube becomes displaced (when trying to clean it, ignite it with matches (and probably everyone has tried this), or in the “hearts” - they tapped the tube with something).
If you pay attention, you will see that the tube is not rigidly attached to the gas outlet from the column. Try adjusting the gap between the gas supply hole in the tube and the igniter tube itself, so that air gets into the tube along with the gas and draft appears. You will immediately see that the flame from the igniter will lengthen and “lie” more horizontally and will reach the thermocouple. And the wick will light up more stable from the piezo spark.
Question: Can you tell me where the Junkers WR-275-1 geyser can have water pressure adjustment? The instructions only describe adjusting the gas pressure (screw under the sealed lid), but nothing is written about water. I suspect the healthy screw is at the very bottom of the block, but I would like to clarify.
Answer: This means there is no water pressure adjustment. On such columns, only a flow regulator is installed - a large knob on the front panel. But for real pressure regulation you need a reducer - they are not installed in columns.
Question: Column Junkers WR 275-1, everything worked fine before. It hasn't been used for about a year, and now the gas doesn't turn on when you turn on the water (the ignition is still on). Please advise what can be adjusted there?
Answer: The rod is soured or the membrane of the hydraulic flow sensor is torn. Maybe gas regulator is in the “Ignition” position. If the former, then try to disassemble and check the rod and membrane. The hydraulic unit is located at the water inlet to the column. This is a large flat round frog to which two pipes are screwed - from the input cold water and a tube going to the heat exchanger. It is necessary to unscrew both water tubes and remove the assembly.
As a rule, it is fixed with 2-3 screws. After removing the assembly, you will see a thin rod that presses on the gas control valve. Once you disassemble the unit, you will immediately understand its design. Just remember the position in which the membrane is placed. Inspect the membrane for tears. If the membrane is damaged, then only replace the membrane, but this is very rare. It is best to lubricate the rod with a greasy, water-resistant lubricant. You can disassemble the hydraulic unit as much as you like, but don’t get into the gas part. The malfunction is standard, it can be treated quickly and without problems.
Question: There is the following problem with the Junkers WR 275 gas water heater. To start the water heater, you need to turn on the hot water at full blast, reducing the pressure - the water heater goes out. I monitored the reaction of the column to manipulation of the hot water tap - it reacts, but only in the upper position, that is, it is not possible to set a convenient low pressure; when washing dishes, for example, water scatters throughout the kitchen. It is not possible to measure the water pressure in the system; it is impossible to hold the water in the tap by turning it off with your finger (due to the pressure). Is it possible to somehow make the column react and turn on with less water pressure?
Answer: All speakers do not like to work on a small flow. If it worked fine before, but now it has become bad, then disassemble the frog and change the elongated membrane. At the same time, it is very useful to lubricate the rod with a fatty, water-resistant lubricant. This unit is responsible for turning the gas on/off.
Question: How can I turn down the gas supply when the water is very hot? The lamb is turned all the way down. Does not help.
Answer: There are two user adjustments on Junkers WR 275 geysers. The first is a lamb, which can be used to reduce the temperature at the outlet of the device by allowing part of the flow to bypass the Venturi. the second is the burner power control knob. Has three positions - burner off, ignition - minimum power, maximum power. If the water temperature is still hot when the flow regulator is fully open, move the burner power regulator to the minimum position - the temperature should drop. If not, then look for the gas supply adjusting screw. It's under an aluminum cap. It’s always like this for summer, but you’ll have to put it back for winter.
Question: Yesterday the gas heater went out when the hot water was turned on, I tried to light it, but it didn’t work. I put the slider in the center, click on it, click the piezo. The wick burns while I press the slider, as soon as I let go the wick goes out. I tried a hundred options, but the wick goes out. Tell me if anyone knows what the reason is?
Answer: the thermocouple is washed by the igniter flame; it must be completely in the flame. there is a blockage and the flame barely touches it, then such a defect is possible or the thermocouple itself is covered
Question: We use a Junkers gas water heater. If gas does not flow due to incorrect adjustment, how can I check/adjust it correctly?
Answer: There are two types of speakers: 1. With a constantly burning igniter. Everything is extremely simple there. I pressed the start button, the gas went only to the igniter, ignited it with a piezo ignition or a match, the igniter caught fire. Wait 10-15 seconds during which the gas control thermocouple warms up and you can release the start button. The igniter burns due to the flow of gas through a valve, the coil of which is powered by electricity from a thermocouple.
Please note that there is a safety thermostat in series with this coil. poor traction, located at the top of the column near the chimney connection. The operating philosophy of all speakers is the same, regardless of manufacturer. Basically, the speakers of this type Any technically competent person can repair it. The main thing is not to climb into the gas part. It is, as a rule, eternal. All faults in these columns are in the plumbing or weak chimney draft.
2. Junkers geysers with automatic start. Everything is more complicated there. The gas ignition circuit is started by a signal from a microswitch, which is triggered by a water flow sensor. After this, the gas supply valve to the igniter opens, which supplies gas for about 15-20 seconds, and then turns off. Simultaneously with this valve, the ignition spark generator begins to operate. The control circuit begins to control the ignition of the igniter based on the ionization current (for this purpose, there is another electrode next to the ignition electrode).
There is no thermocouple there. If the ionization current does not appear within 15-20 seconds, then the gas supply to the igniter and spark generation will stop. Then everything will repeat only after closing/opening the water. When an ionization current appears (ignition of the pilot), the control circuit gives a signal to open the main gas valve, which opens gas to the burner.
There is a modulation unit in series with the burner, which regulates the gas supply depending on the water flow rate and the readings of the hot water temperature sensor. Often a power regulator (winter/summer mode) is installed in the gas path, which limits the power of the burner. Naturally, the gas supply stops when the low draft sensor is triggered or when the water flow stops.

Gas water heaters are necessary for houses and apartments that do not have a central hot water supply. This technique is safe and reliable, it is easy to use, and it allows you to change the degree of heating, which is a big plus.
Peculiarities
The characteristics of Junkers indicate that the device is ideally suited to Russian conditions. It is adapted to the pressure maintained in Russian gas pipelines and is equal to 13 millibars. In addition, the system is able to work with the low water pressure inherent in Russian water supply systems. For Junkers, 0.1 atmospheres is enough to perform the intended functions.
Such a gas burner is capable of heating from 11 to 16 liters of water per minute, which is considered a very high figure. In addition, the flame power automatically changes depending on the strength and size of the water flow. The structures are safe and can serve for a decent time. The devices are able to provide fast water heating and look great, which explains their popularity around the world.
Strict design, a variety of models differing in performance, design and ignition system, affordable price and simple controls are among their main advantages.
Design and principle of operation
A typical column consists of a casing that is connected to the chimney through a pipe, a heat exchanger (the best is copper), gas burner, ignition system, sensors and mechanism responsible for gas supply. The gas water heater is connected quite simply.
Its operating principle can be examined on a model that has piezo ignition.
- The slider is set to the middle position, after which you need to click on it. At this moment, the valve opens and gas enters the wick, also known as the igniter.
- The piezoelectric element, located at the bottom left of the gas column, supplies a spark that ignites the gas. In this case, the slider button is kept pressed for up to 40 seconds. When it is released, the wick still continues to burn.
- At this time, the thermocouple of the column is heated, which will then keep the electromagnetic gas valve open.
You can set the required water and gas consumption.
Varieties
In general, all Junkers speakers can be divided into three groups, depending on the ignition method.
- Those that belong to the B series do not have an igniter that can burn continuously. Two batteries are responsible for ignition, and the speaker itself turns on automatically. Safety systems control draft and flame, there is a fuse. The water pressure in the water supply affects the temperature.
- The P series operates on the basis of piezo ignition. This means that the igniter does not stop working. Water and power have to be adjusted separately.
- Finally, the G series models work thanks to HydroPower technology. There is no igniter at all, and a hydrodynamic generator is responsible for ignition.
Such a water heater can serve up to three water points.
The models produced are standard and mini. The difference between them is only in size. Prices for Junkers brand products are determined based on dimensions and such additional services like delivery and installation. Reviews are most often positive character. Users only mention the need to timely clean equipment and remove blockages.
Preference is most often given to Junkers brand models with piezo ignition. When the hot water tap opens, gas will flow to the main burner. As a result, it will ignite from the pilot and heat the water.
Installation and connection
It is better to entrust installation and connection to a specialist who has been trained in working with this type of equipment. In addition, he will be able to suggest which original spare parts are worth purchasing, diagnose the equipment and prevent any malfunctions from occurring. However, even a professional must follow the instructions that are sold along with the product itself.
- The column is usually mounted in a warm room near the chimney so that the supply of combustion air is not obstructed. Need for additional protection There are no flammable surfaces. The device is installed in compliance with the required gaps separating it from the wall and furniture. The room temperature should be positive.
- First of all, the casing is removed, then it tilts towards itself and rises up. Having connected Junkers to the gas network, you need to install shut-off valves as close to installation as possible. Before connecting to the water supply pipes, they will need to be thoroughly washed, otherwise sand, lime and other contaminants will lead to a delay in water supply. Both pipelines (gas and water) must be ideally combined with the parameters of the column.
- To avoid blockages, it is necessary to install protective filters.
- The column is attached to the wall using brackets. It should not rest on water or gas pipes. If the speaker has an electric ignition, you will need to insert two batteries with a power of 1.5 Volts.
- At the end of work stopcock and the water valves are closed, and the operation of the draft sensor is checked. The launch occurs according to the instructions.
Operating rules
It should be remembered that some actions can lead to damage to the gas water heater. Junkers operations will be disrupted if inflow is not ensured fresh air. In addition, breakdowns will occur when using too long hoses, which lead to a decrease in pressure and the simultaneous opening of hot and cold taps. Naturally, the lack of periodic prevention will also lead to negative consequences.
It was already indicated above how you can turn on the Junkers column - this is done using a valve and a piezoelectric element that can light the wick. Once you light the burner, it will work throughout the day. Moreover, as soon as the hot water tap opens, the boiler will be connected automatically. You can change the gas pressure and water pressure by switching two control knobs.
If you decide to clean gas equipment, this is done according to a certain algorithm.
- First, the gas and water are turned off, then the casing is removed.
- At the next stage, the water unit and smoke receiver are dismantled.
- Finally, the heat exchanger is removed at the end. The radiator can be washed in warm water with a non-abrasive cleaning solution added. The brush should be long-haired and quite stiff.
- The wick and main burner can be easily cleaned using a special awl. In addition, you will have to remove carbon deposits from each injector. However, it is not recommended to do this yourself. Better time invite a specialist per year who will combine inspection with descaling. The professional will also remove deposits, check the tightness of the fittings and clean the plates on the flue gas side.
If you smell gas, do not use it. electrical switches and a telephone in the area where the gas burner is located. It is important to immediately close gas tap, open the windows, ventilate the room and call the specialists who installed the equipment. To prevent dangerous situations, do not store liquids or objects that are prone to ignition near Junkers.
When the room temperature drops below zero degrees, the burner turns off and empties. If before winter months such a procedure was not carried out, then when connecting the device the next season, you need to check whether the water is heated.
Possible faults
