BOSCH WR 13-2B23 (GWH 13-2COB)

Advantages: 1.Automatic mode 2.Works perfectly with modern mixers 3.Temperature can be changed by the mixer handle 4.Copper heat exchanger, repairable by soldering

Disadvantages: 1.After 2.5 years, a hole formed in the heat exchanger, through which the microphone was beating 2.Very high cost of installation, service and spare parts

Comment: As usual, they started looking for a new speaker during the renovation of the apartment. At the same time, the main parameters were automatic mode and safety, which only a well-known brand could provide. Memories of an ancient burner in a communal apartment in Petrogradka St. Petersburg, an ever-burning fuse, claps, etc. only intensified the striving for the best in heating engineering. The column worked without problems for 2.5 years. Until a serious refusal, the results of the crooked handles of the would-be installers withstood: the neighbors installed a new column and confused "gas" and "water". For a long time I could not figure it out: I went into the kitchen in the morning and saw a thin trickle of water beating from the corrugation connecting the gas pipe and the column. And so it began: calls to the emergency gang, pumping out water, etc. While the gasmen were drying the pipes and bypassing the residents of the house, more than one day passed. When the epic ended, the column started without problems, although in my thoughts I had already parted with it and was considering a plan to compensate for the damage from negligent neighbors. After such tests, my faith in Bosch and German technology has grown significantly. But it was not there. Six months later .. one afternoon I noticed a microscopic fountain, to which I was led with wet spots on the wall (then I remembered a bad word from the neighbors above). But a detailed inspection showed the presence of microcracks on the heat exchanger tube. No Bosch certified firm has undertaken the repair of this part. We were delighted with the cost of a new heat exchanger (like a new column), complaining about the lack of service work (once a year, not cheap), which led to the early failure of such a wonderful and reliable equipment. Upset, losing hope of a quick meeting with hot water, I went to the Internet in search of companies that would not be afraid to restore the masterpiece of German technology. And, lo and behold, such was found, soldered quickly and inexpensively. It is working .. A Bosch MES3000 juicer has joined it, but we are not sure about the future purchase of a coffee machine of the same name, as they say - the sediment remained.

Advantages: The electronic control unit, the wick does not burn constantly, I opened the tap and it ignites itself, there is enough power to use water simultaneously in the kitchen and in the bath. after the old Soviet column it's just a miracle, we are happy.

Disadvantages: incomprehensible temperature control, you turn the knob and little changes, it all depends on the water pressure

Comment: We called a specialist from the Bosch service center to connect

Advantages: Not noisy compared to other brands. Reliable, only batteries every 6 months. changing. Works without complaints for 2 years. A weak pressure of water and gas is enough for work. Ugh ugh, as if not to jinx it.

Disadvantages: 1. Local gas workers refused to accept it for service. 2. Expensive service. 3. If a pipe with 1/2 gas is supplied, it is not a fact that it will work 100%.

Comment: Good and worth the money technology. I installed it myself and connected it myself. Nothing complicated, the main thing is to withstand the norms. The gasmen came, checked, said that everything was fine. The only thing that did not start the first time, I had to call the master and bleed the air from the gearbox. After which it did not bug.

Advantages: Before it was the old domestic years of the 70s - what's the comparison? If you clean the gas part every 2 years, then there would be no special problems

Disadvantages: It worked for 7.5 years instead of the declared 10 service life. At first, the oil seal leaked on the temperature adjustment - the replacement did not give anything, the production in the seat, or maybe the master did not have a native, and yesterday the radiator leaked and today took it to the trash heap, having bought a new one

Comment: Friends of 2 mora have been working for 9-10 years

Advantages: Auto ignition, silence, performance, reliability, design, build quality.

Disadvantages: In order for the column to turn on, you need to open the tap quite strongly.

Comment: The column has been working with us for six years now. At the same time, they cleaned it only once, due to the fact that it seemed to me that it became weaker to heat, somewhere after three years of operation. The master was surprised that the column practically did not need to be cleaned, said that most likely due to the fact that our house has a very strong water pressure. (Khrushchev, 2nd floor). The master installed and cleaned from the service center. Now we have moved to the Stalinka 5th floor here, the pressure is frankly weak and I will probably buy another column model here, it seems to me that the pressure is very important for this model. And yet I bought this model again and in the Stalin era. The box says that the column is made in Portugal, assembled very high quality, has been working for almost half a year now, very happy with it. The pressure became stronger after replacing the pipes, at the same time, a new column was installed.

Advantages: Compact, good service

Disadvantages: goes out with relatively little mixing of cold water. not clear visually the stroke of the setting knob head / temperature

Comment: Honestly, from the moment of installation to the moment of normal operation, it took about 3 months ... all this time there were "dances with a tambourine". Initially, there was a very weak pressure or just cold water. I called the BOSCH serviceman,who measured the gas pressure at the inlet to the column and said that he sees a strong drop, which should not be. Immediately advised to cut off the gas meter. GorGaz did not believe in this and came to see how the column works, while twisting the pressure adjustment knob ... after 3 months and paying 5000r to GorGaz, the meter was cut off and the column "came to life". And the sound became different and the temperature of the water. I don’t blame the column for this, rather the nuances of the speed of the gas station and the meter (by the way, there were no complaints about it before in the gas station - "SGM4". And about other meters, the gas workers themselves said that they greatly underestimate the pressure in the networks and the columns do not work in This BOSCH was said to work from an old counter of the SGK type). However, perhaps these are the nuances of my house (stalinka 3rd floor)

Advantages: An excellent speaker, quiet and simply beautiful.

Disadvantages: They are not there if you set it CORRECTLY.

Comment: When connecting with a gas hose, use only corrugated stainless steel with a diameter of 1/2 (15mm). It will work with rubber in a metal braid (9mm), but the water will not heat. This is very important !!!!!!!

Advantages: Good in everything

Disadvantages: I will not say anything bad

Comment: The right knob regulates the heating of the water due to the flow and the adjustment is carried out roughly in a large temperature range. The left knob is used to adjust the water heating due to the gas supply. The adjustment is carried out in a small temperature range and serves for precise regulation. Two knobs achieve a comfortable ratio of the amount of water and its heating. 89262349541

Advantages: beautiful appearance, quiet operation, high-quality assembly

Disadvantages: did not notice

Comment: It works great, there is no noise during heating, it has been working for 4 years, I think it will work a lot without problems. We made the right choice !!!

Advantages: Easy installation. Has been working for over a year without any complaints. The batteries are still the ones in the box and have not been replaced.

Disadvantages: If you open the tap a little to get a jet with a diameter of 8-10 mm, the column does not ignite. More water consumption is required for ignition. Quite large!

Comment: Nice speaker. Put it and forget it :-)
