A Junkers geyser installed in your home will provide quick preparation of hot water and will delight you with its excellent appearance. This is modern water heating equipment manufactured using advanced technologies. However, the use of advanced developments did not deprive Junkers geysers of certain disadvantages. However, they are found in many houses and apartments. Here are the main advantages of these speakers:

• Excellent appearance – Junkers speakers have an excellent, strict design;
• Wide range of performance options;
• Convenient control – a minimum of control elements.

Buyers have a large selection of columns to choose from, differing in their performance, thermal power and type of ignition system. Unfortunately, there are no design solutions. Their main advantage is their affordable price. Flow-through geysers from this manufacturer are offered in many stores selling water heating equipment and gas equipment. What do reviews say about Junkers geysers? Our review will tell you about this.

Junkers geysers have received many positive and negative reviews. After reading them, you will be able to make the right choice and choose the most reliable gas water heater.

Geyser Junkers WR 13P

Gennady
We bought a Junkers WR 13P gas water heater less than a year ago and are already planning to replace it. By its design, the column resembles a leaky sieve - water flows from all the holes, and the heat exchanger has already been soldered a couple of times. There is a feeling that the heat exchanger itself is made of thin foil and is completely unsuitable for working in gas equipment. Not a week goes by that I don't have to tighten or patch something, it just drives me nuts. The seals are constantly leaking, and the gas reducer failed after only a couple of months of operation. If you want to keep your nerves strong, do not buy this water heater; it is better to buy a Bosch gas water heater.

Advantages:

• Electric ignition, thanks to which the column is freed from a constantly burning igniter;
• Works well at reduced pressure, gas is ignited confidently and without hesitation;
• Maximum capacity 13 l/min, which is what is needed for two taps.

Flaws:

• Everything that can leak leaks, from the seals to the heat exchanger;
• It makes noise during operation like an old Soviet speaker.

How to light according to ignition type

Manual ignition

This method is already outdated and is used extremely rarely in modern speakers. Such devices are poorly protected both from changes in water pressure and from fire extinguishing.

It is currently not recommended to install such devices at home.

How to light a column with manual ignition:

• Unscrew the valve on the tap that supplies water to the column.
• Light the wick using a match or lighter.
• Open the valve on the tap supplying gas to the column.
• Sometimes, in order to ignite the burner, you need to wait a little until the air comes out of its channel. To speed up the process, first open and then close the hot water tap several times.

Piezo ignition

This option of igniting the column is more modern and widespread. It is very simple to use, but it has the disadvantage of increased gas consumption. While the column is not working, the wick is still smoldering inside it, so the gas, although in small quantities, is constantly burned.

How to light a column with piezo ignition:

• To start, you need to press a button that acts on the piezoelectric element. This will provide a spark to ignite the pilot wick.
• Open the tap supplying gas to the device.

The following video demonstrates this clearly.

Automatic ignition

This is the most modern and profitable option for igniting geysers. It is also called electric because it is based on the transmission of an electric spark. Its appearance is provided either by batteries or a hydraulic turbine. The combustion will be controlled by different sensors, and as soon as the user turns off the hot water tap, the ignition wick will go out.

How to light a column with electric ignition:

• Make sure that gas and cold water are supplied to the column.
• Open the hot water tap.

Watch a short video review.

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. The average service life of a Junkers column exceeds 15 years.

Behind the strict appearance and good performance lies a poor filling, not much different from the filling of domestic Oasis geysers. Let's start with the heat exchanger - it is incredibly thin, it leaked six months after purchasing the column. Then the gaskets began to leak, they had to be constantly changed, otherwise the neighbors could be flooded. Sometimes the igniter goes out because the gas control is triggered - and it is impossible to understand why it suddenly triggers. It is impossible to repair its “guts”, since everything is very thin, flimsy, and cannot be repaired; I don’t even know how it was developed and how it is produced - this is one continuous drawback. And even the fact that it can work with low pressure does not justify its snotty fragility. This is not a column, this is complete torture.

Advantages:

• Easy control, no extra knobs and buttons, temperature can be easily adjusted;
• Good performance, you can open two taps at once or take a shower while someone else is washing the dishes;
• It doesn't make much noise and doesn't scare anyone with its noise.

Flaws:

• This column itself has one big drawback, since literally everything in it breaks;
• Terrible heat exchanger, thin copper that cannot withstand heat;
• It constantly flows, threatening to flood the neighbors. Who knows how she will break through next time;
• It cannot be repaired, since it is impossible to repair these “snots”.

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 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 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.

Overall, it’s a good column; it served me for three years, after which its heat exchanger began to leak. Disassembly showed that a crack had formed in it. This was the most serious malfunction, and for three years it worked properly. As it turned out, a flimsy heat exchanger is a disease of all geysers from this manufacturer. The fact is quite strange, considering that the trademark belongs to such a well-known company as Bosch. The verdict is this - if you are lucky with the heat exchanger, the geyser will last a long time. If you are unlucky, you will have to constantly solder the heat exchanger.

Advantages:

• The absence of batteries allows you to get rid of unnecessary expenses, since ignition is carried out from a miniature generator rotating under water pressure;
• Solid appearance, no frills;
• Capacity up to 13 l/min, this is enough for a washbasin and shower.

Flaws:

• The heat exchanger is flimsy, leaks regularly and requires soldering. Moreover, soldering does not help for long;
• Sometimes it goes out for no apparent reason, which I have never been able to find.

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), a gas burner, an ignition system, sensors and a mechanism responsible for supplying gas. 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.

If the burner at the Junkers gas water heater does not light, it’s time to clean the igniter. I came to this conclusion after a year of fiddling with the miniMAXX WR 10P speaker. The device is not bad, but it is not without some shortcomings - and the burner is eloquent proof of this. I bought this speaker for reasons of economy, so I took the model with the minimum power, since I live alone, and usually either the faucet or the shower works for me. The column quickly heats the water and ignites without popping or roaring. I was pleased with the presence of overheating protection and a gas control system - this makes the speaker safer.

Advantages:

• Quick heating of water, no need to wait long for it to warm up;
• There are a minimum of controls, there are no unnecessary things, such as self-diagnosis systems;
• Extremely simple design, you can repair the device yourself, without calling a technician;
• No need to spend money on batteries.

Flaws:

• There are often problems with the operation of the igniter, but the burner itself almost never goes out;
• The manufacturer promised trouble-free starting with minimal pressure, but I would not say that it always starts - in the summer it starts after two or three attempts, when the water is barely flowing.

Reviews about the main functional characteristics

When visiting a store, modern consumers quite often become interested in Junkers brand products. The gas water heater of this company is an excellent example of this. You should read user reviews before visiting a store to purchase a device.

It is important to consider that the column may have different types of ignition. It is extremely rare to find a device on sale that is characterized by manual ignition, so there is no point in focusing on its features. According to users, models that provide piezo ignition are more convenient. In this case, a special button located on the panel is used. The required water temperature will be set by the regulator located on top.

If you are interested in Junkers, the gas water heater, the instructions for use of which are described in the article, will maintain combustion constantly, which is true after switching on.

We bought this speaker a long time ago. Reading reviews of modern speakers, you can’t help but be amazed at how poor the quality is. But our column has been in service for 7 or 8 years already. During this time, practically nothing broke in it, I only changed the current gaskets a couple of times. But otherwise the model deserves a positive review - it is reliable and works well in low pressure conditions. Quietly heats water up to 55-60 degrees, this is more than enough for the home. True, I would gladly supplement it with a battery-powered ignition - and then it would not be worth it.

Advantages:

• Reliability and stability, has never failed. It's immediately clear that the developer spared no effort on the materials;
• Heats water quickly, to almost any temperature needed in everyday life;
• There is practically no noise when heating water.

Flaws:

• Piezoelectric ignition is not very convenient; I prefer battery-powered ignition. And so we have to turn off the igniter when we leave for a long time.

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 is equipped with detailed instructions, which describe 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 inept installer.

The device has a large number of positive reviews from satisfied customers. They consider it a reliable, safe and affordable device.

I wanted to throw away this device immediately after purchasing it. Unfortunately, we were removed from the warranty because my husband decided to repair the speaker himself, but due to its unfinished condition, the situation only worsened. As it turned out, these speakers are not repairable at all. It's easier to throw it away than to try to repair it. As a result, it didn’t work for even a year, we saved up some money and bought a normal speaker from Bosch, and sent this heresy to the landfill, where it belongs.

Advantages:

• Affordable price, which hides a whole trunk of shortcomings;
• Not a bad look.

Flaws:

• If something in it breaks, it will be impossible to repair the column;
• It leaks, causing damage to kitchen furniture;
• The gas is ignited with a bang, scaring the child. During operation it makes a lot of noise, like a rocket;
• It constantly goes out when the pressure changes, the igniter also does not light up, it had to be cleaned often.

Common breakdowns

Often the device breaks down due to improper use. It happens that this happens due to corrosion, poor water quality and electrical surges. 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.

Operating rules

It should be remembered that some actions can lead to damage to the gas water heater. Junkers operation will be disrupted if fresh air is not provided. 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. It is better to invite a specialist once a year who will combine an 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 there is a smell of gas, it is prohibited to use electrical switches and telephones in the area where the gas burner is located. It is important to immediately turn off the 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.
