With ease of installation, operation and safety geysers Junkers are gaining popularity both in private homes and in ordinary high-rise buildings. Such a device will be very useful in families with small children, because due to frequent shutdowns of the hot water supply, the child can get sick, and constantly heating water on a gas stove is not very convenient.
Types of speakers
All German Junkers gas water heaters are equipped various types igniter This serves as the basis for distinguishing them from each other. Gas water heaters are produced in the following versions:
- Junkers V;
- Junkers R;
- Junkers G.
The first type of speakers does not have a burning igniter, so ignition in it occurs using two batteries.
The water column in this case is fully automated and therefore it starts itself, controls the level of water pressure and monitors the pressure in the water supply in order to correctly set the heating mode. It is also equipped with a sensor that will notify the owner at the right time about any malfunctions in the column, which will help eliminate the malfunction as soon as possible and prevent breakdown of the entire device.
If you look at the customer reviews of this version of the speaker, you can conclude that its service life is more than 10 years, which is a big plus in comparison with analogues.
Junkers R is equipped with piezo ignition, that is, the igniter that is installed in the device will be constantly ignited when the device is operating. It is not automated, so you will have to independently regulate the water pressure in the system.
Type G is equipped with a hydrodynamic generator, which ignites the burner (it does not have an igniter). This device is capable of operating at a pressure of 0.35 ATM and is equipped with Hydro Power technology. Also this type of Junkers column Available in two sizes:
- standard;
- mini.
All the components are the same, the only difference is the size.
Advantages and Disadvantages
The device has both advantages and disadvantages. The advantages include the following characteristics:
- equipped with flame modulation;
- increased security;
- adaptability for use in Russia;
- wonderful appearance.
Thanks to its design, Junkers will fit perfectly into any interior. The device operates at a gas pressure of 13 Mbar. This pressure is present in all gas pipelines in Russian homes. If we compare it with European pressure (20 Mbar), then it is significantly lower, which creates problems when purchasing other geysers. The device operates effectively in multi-storey building, where the pressure in plumbing system very low (works from 0.1 ATM.)
Junkers has increased safety and low cost compared to its analogues. When the water pressure changes, the device will automatically select the power at which water heating will be optimal. The device is assembled by German designers and has a 2-year warranty. At correct installation and operation, the device can last more than 13 years.
Among the disadvantages are the fact that in most modifications of Junkers geysers there is an increased noise level. During operation of the device, problems appear with the heat exchanger and leaks in the seals, which creates a risk of damage flooring under the gas water heater or completely flood your neighbors.
Common breakdowns
Often the device breaks down due to improper use. It happens that this happens due to corrosion, poor water quality and surges electrical voltage. If a defect is discovered after purchase, it will be repaired free of charge at the service center.
Paid repairs will cost approximately 1,500 rubles. The price depends on the complexity of the breakdown. It is recommended to take the device to the service yourself in order to save on delivery or calling a private technician. The most common malfunctions are:
- water leak;
- overheat;
- the occurrence of loud sounds emanating from the device;
- the water does not heat up;
- The sensor stopped working.
Basically, these breakdowns occur due to the formation of a large layer of scale. In order to repair the device yourself, you need to determine the cause, purchase original spare parts, follow the recommendations of specialists and study the basic rules for repairing this type of boiler.
After repairs, you must make sure that all fastenings of the device are correctly secured and that no gas leaks occur during operation. Repairing the device yourself is only permitted if you have such experience. Only original spare parts purchased from Bosch should be used.
Device cost
The cost of the device depends entirely on the size (standard or mini) and its version (B, P, G). On average, the price for type B varies from 10 to 13 thousand rubles, for type P from 6.8 to 9.7 thousand rubles, for version G from 11 to 12 thousand rubles.
Each device comes with detailed instructions, which describes the technical components of the device, instructions for installation, configuration and care of it. The manufacturer recommends not to install the device yourself, but to trust specialists from the gas service. After all incorrect installation can not only break the device, but also cause significant harm to an incompetent installer.
The device has a large number of positive reviews from satisfied customers. They consider it a reliable, safe and affordable device.
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 column thermocouple is heated, which will then support 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. 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 tap opens hot water, gas will be supplied 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. There is no need for additional protection of 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 the Junkers to the gas network, it is necessary to install shut-off valves as close to the installation as possible. Before connecting to the water supply pipes, they will need to be thoroughly rinsed, 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 the work, the shut-off valve and 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, where a non-abrasive cleaning solution has been 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 such a procedure was not carried out before the winter months, then when connecting the device the next season, you need to check whether the water is heated.
Possible faults
Of course, the operation of any equipment does not always go smoothly; you should be prepared for anything. Fortunately, a significant part of the possible malfunctions that occur with a Junkers geyser can be easily resolved on your own.
There are actually many reasons why the burner does not light.
- It may turn out that both the inlet and outlet pipes were initially installed incorrectly. In addition, the water supply may be disrupted.
- Possible problems with traction. When the chimney is dirty, combustion products do not escape, but accumulate inside, which slows down the operation of the equipment. Craving also suffers due to the lack of fresh air, for example, when the window is closed.
- It happens that the chimney becomes blocked, and this creates a potentially dangerous situation. We urgently need to turn off Junkers and call specialists.
- If the pilot flame goes out, this indicates that the protective relay requires replacement.
- It may simply turn out that the burner does not light because the battery is discharged, and therefore the automatic ignition system does not function. You will have to disassemble the front panel and charge it yourself or replace the battery.
- Low pressure in the main leads to poor water supply, which again leads to operational problems.
- The wick goes out when the flame is uneven. As a result, the main burner also turns off. To solve this problem, simply clean the device.
Sometimes the Junkers speaker does not light up, and sometimes the device turns itself off.
- The first reason is that the batteries have become unusable.
- The second reason is that it is necessary to change the membrane, which has become deformed or torn. It's good when the repair kit contains a replacement.
- Next possible option The problem is that one of the control sensors does not work or the microswitch is worn out, this can be determined by the absence of a characteristic click.
In addition, the igniter may become clogged from the inside, which can be easily fixed by cleaning. An abundance of rust, dirt in filters due to poor quality water and electrodes leads to similar consequences. Finally, improper installation, a closed valve on a gas pipeline, and problems with wires are also common causes of service interruptions.

Why one article at once about speakers from two different brands, Junkers and Bosch? At their core, the Junkers WR-11 and Bosch WR-10 speakers are the same speaker. They have slight differences in the body and handles. For example, on Junkers dispensers you can find a tap that is attached to a water block and is sold together with the dispenser. This is where the differences, in general, end. Inside the case there is the same filling. Both speakers are semi-automatic and have proven themselves well for their simplicity, maintainability, and the price of new products. They have been very popular in Russia for a long time. You can do the repair of these geysers yourself using my step by step instructions showdown.
How does this column work? In order to light it, you need to set the slider on the front panel to the middle position and press on it. Thus, we forcibly open the electromagnetic gas valve and supply gas to the igniter (wick) of the gas water heater. In order for the gas to ignite, it must be ignited with a piezoelectric element, which is located in the lower left corner of the gas column. After the spark has ignited the gas coming out of the wick (igniter), you must continue to hold the slider button pressed for 10 to 40 seconds. At this time, the column thermocouple is heated. Then release the slider, the wick should continue to burn without pressing. If this does not happen, then you must repeat the entire procedure from the beginning. If the igniter does not light up, then most likely the column requires repair or maintenance, cleaning the wick (igniter). After the thermocouple has warmed up, it generates an EMF, which independently holds the electromagnetic gas valve of the column in the open position. The column is ready for use. All that remains is to set the gas flow rate you need using the slider and the water flow rate on the water block.
What happens when you open a tap hot water mixer? Everything else is simple. The membrane of the water block presses on the rod, which in turn opens the mechanical gas valve, and gas is supplied to the main burner of the Bosch (Junkers) column. The gas mixture is ignited by the burning igniter wick and heats the water, which flows through the radiator of the gas water heater.
1.Remove the handle from the water block, set the gas regulator slider to the middle position, unscrew the two self-tapping screws from the bottom of the speaker body (on Junkers there may just be snap-clips) and remove the body.
2. Unscrew the two self-tapping screws securing the cap of the gas exhaust device to the body of the column and two self-tapping screws on the strip attached to the cap, which secures the radiator (heat exchanger) of the gas column.
3. Remove draft sensor 1 (it is located on the right side of the smoke exhaust hood), disconnect the wires from it. Remove temperature sensor 2 from the heat exchanger by disconnecting the automation wires from it. Here Junkers and Bosch have slight differences. For Bosch, the wires from the traction sensor are removed, for Junkers they are soldered. Don't try to remove them - you'll only break them.
4. Next, nothing prevents us from disconnecting the gas exhaust cap from the heat exchanger (radiator) and the column body. 
5. To remove the heat exchanger, it is necessary to remove the threaded pipe from the left pipe of the heat exchanger, having first removed the latch. Instead of removing the threaded pipe, you can unscrew the hot water hose from it. From the right pipe of the heat exchanger, you need to remove the tube that connects the heat exchanger to the water block of the gas water heater. It is also attached to a latch; after removing the latter, it can be removed. Rubber rings are used as seals in both pipes. They often leak after disassembly and reassembly, because... rubber ages and dries out. It must be disassembled carefully. When assembling, I advise you to change the rubber bands; in any case, lubricate the pipes during assembly.

6. Nothing prevents us from removing the heat exchanger. Although... Bosch has back wall The housing is stamped with two brackets for the heat exchanger. It is better to bend them upward. They are not particularly needed and do not affect anything. After this, remove the geyser heat exchanger upwards.
7. Disconnect the pilot tube from the burner. It is secured at the top with such a bracket (if it hasn’t been thrown out before you) and in the area of the jet it is secured in a latch. Use a screwdriver to pry up the tube in the area of the latch and remove it from the grooves at the top.
8. Behind the igniter tube there is a ceramic ignition electrode. It is also attached with a quick-release latch and can be easily removed.
9. In order to remove the burner, we unscrew a pair of screws that secure the burner to the body of the gas water heater, and a pair of screws that secure the burner in the gas block of the water heater. Next, gently press the thermocouple down with a screwdriver so that it comes out of the burner body. You can stagger the burner upwards from the gas block.
10. To clean the burner, we disassemble it into parts. To do this we need to unscrew 4 screws. We separate the two parts of the burner from the gas train.
Actually, the disassembly of the column is completed. For maintenance (cleaning) this is quite enough. Gas block Usually it doesn’t break if no one has climbed there. There's nothing to do there. This is a factory product. If necessary, you can also remove the water block and disassemble it to replace the membrane or oil seal cover.
We carefully wipe the disassembled elements, rinse them from dust, soot and other deposits.
Particular attention to the heat exchanger. I wash it both outside and inside with chemicals or solution citric acid. By the way, it really eats away scale and rust from the inside. If the water is from a well with increased hardness, then this simply must be done every time. maintenance, because it is overgrown from the inside so that it is impossible to blow it out with a compressor. Scale and soot impair heat transfer, increase gas consumption, and can lead to heat exchanger failure. Burnt-out heat exchangers on these columns are rare, but those clogged with soot are very common. Both the Bosch and Junkers water heaters begin to heat the water poorly. Usually, all these “shoals” emerge at the beginning of winter, when water through the pipes begins to flow colder than in summer.
Dust accumulates in the burner, which enters the apparatus with air, and combustion products fall onto the openings from above. You can’t clean the burner in this column without disassembling it, so drive away all those who suggest you clean the column with a vacuum cleaner—they’re freeloaders!
Thoroughly clean the thermocouple of carbon deposits and soot. I have not encountered burnt thermocouples on these columns. It is better to wipe the insulator of the piezo ignition electrode from carbon deposits and dirt with alcohol, no matter how much it sticks onto the body. Thoroughly blow out any dust from the igniter tube. Most often, because of this dirt in the tube, the wick becomes weak, smokes, does not heat the thermocouple well, and the column may go out and not ignite. Cleaning the tube usually solves the problem and the column wick lights up. Ideally, the pilot flame should be blue and hit the thermocouple horizontally. If the wick flame is yellow and the large “tongue” goes up, the igniter clearly needs to be cleaned.
Now about malfunctions of Junkers and Bosh speakers
- As I wrote above, the column is assembled on rubber O-rings. With old speakers they become woody and the seals begin to leak. It’s good if the master has them. You often come across different collective farm options from windings to sealants.
- The membrane of the water block, unlike the membranes of Chinese speakers, lasts a very long time. I encountered a torn membrane once. The price of the original membrane is about 1800 rubles, the Chinese equivalent costs around 400 rubles. Who will find it? There is no point in the original, because the prices are astronomical.
- The assembled geyser water block costs around 4500-5000 rubles. The price is high. Seal repair kits for sale. You can sort out the water block yourself. Often the flow regulator leaks at the block. This can be treated by replacing the O-ring.
- It is rare, but leakage of the water block rod seal occurs. Unfortunately, the oil seal cannot be replaced separately. Replaces with water block cover. The price of the cap with a rod is 2700 rubles. Very expensive!
- On Junkers (Junkers) the traction sensor and overheating sensor are often tormented. Sometimes it’s so painful that I change the entire set of thermocouple and sensors. If changing the automation was not part of the plan, then you can painlessly short-circuit the temperature sensor (many imported gas water heaters do not have one at all). I don’t recommend short-circuiting the traction sensor, something that is clearly needed and has saved more than one life. It stops the gas supply to the column if there is no draft in the chimney. You can short-circuit it for a while, so as not to sit without hot water, and only in order to quickly find a replacement for it.
If you decide to buy such a speaker, then read the reviews on the useful website “Otzovik”. There, everyone described their column and gave ratings. My review is quite old. http://otzovik.com/review_1713020.html
Now I would give this column a solid B+. I recommend buying. Usually everything can be repaired without spare parts. Among the “disadvantages” of the speaker, I would like to note the high price of spare parts. Luckily they don't break often.
If anyone is interested, I’m posting instructions here for Bosch and Junkers gas water heaters
Instructions for the Bosch gas water heater /upload/file/quickdir/201104111631310. instructions for the therm 4000 o type p.pdf
Instructions for the Junkers gas water heater /upload/file/quickdir/gazovaya_kolonka_bosch_junkers_wr10_13_15p_1.pdf

I hope the article was somehow useful to you.
