BOSCH WR 10-2P

Advantages: Superr column, Made in Partugal. You need to buy a 3/4 square for it, because the entrance to the cold water looks to the wall, because of this, you cannot screw the hose in any way, it is strange how it was invented. With this column, the pressure appeared very strong, almost the same as that of cold water, before that there was Electrolux 275, so the pressure with it was initially very small. Bosh heats very well, the temperature is adjustable, piezo ignition without batteries.

Disadvantages: haven't found yet

Comment: the column is sold only in white, I needed a gray one, but they said that it was of very high quality, so I bought it and did not regret it. Be sure to buy hoses for water, called GIANTS, they are wider than ordinary hoses, respectively, and more water passes through them

Advantages: Beautiful design, easy to set up, ease of use, sufficient power for 2 taps, quietness of operation (when the temperature is set to 40C, of ​​course, you can hear it if you turn it on at the highest temperature) guaranteed ignition when the tap is opened from the wick flame relative stability of the set temperature (the first minute fluctuates + _5С) in the entire pressure range !!! work at low pressure 2l / min (for me it is low)

Disadvantages: costs 2 times more expensive than analogs, well, God bless it. justifies the quality of work.

Comment: I had a whole epic about installing and running this column. firstly, I chose it according to reviews and in them I read about adapters from 3/4 to 1/2 inches and about GIANTS hoses. after purchase I studied the instructions and realized that in order for such a column to work well, it should be installed by SPECIALISTS, and in order to survive guarantee, they must be authorized by BOSCH. I called GORGAZ, there was neither a rumor nor a spirit about BOSH columns and about any training courses. but they categorically stated that I would contact them anyway, since without checking them I have no right to use the column. turned to digging from BOSCH. there they convince me that they have the right to commissioning and that I have the right to operate after their installation. I didn't know who to believe, but I decided that I still want a working water heater more than a "legal" one. called the "super-specialists" BOSCH. Pre-bought everything that is needed, namely: * ONE GIANT hose to the cold water inlet (the hot hose was supplied to the hot outlet and immediately 1/2 inch) * to it an ADAPTER from 3/4 to 1/2,* adapter from 3/4 to 1/2 for gas * gaskets for water and gas in my case did not have to take the angle adapter, because the hose twisted and bent normally itself. the "super specialists" came and started ... they attached the column and started to connect it. began to bend and pull the hot water pipe. as a result, when water was supplied from the wall, a fountain began to spray. the pipe cracked from the efforts of the workers. they cut off the pipe, put a nut on and decided to replace MY BOShevsky, now a short hose with our own, long one. brought it, I see, it’s not a GIANT, but simple, like a crane. I say that this will not work. experts ask why. I explain that the head is less due to the smaller diameter and the column is automatically cut in terms of performance. only after that they brought THEIR BOSH-cue and increased. they do not know about the setting and I did not dare to ask them to set up. the factory settings were fine. THERE IS NO QUALIFIED SERVICE IN RUSSIA! CONCLUSION: The column is good, BUT FOLLOW THE INSTALLATION!

Advantages: Everything suits me

Disadvantages: Didn't find it.

Comment: After 3 years of use, I would like to share complete information: Main problems and how to solve: 1) The igniter goes out. Just got dusty. Remove the cover, blow-clean. Everything will work again. 2) Weak pressure. The water inlet filter is clogged. Remove the U-shaped pin, remove the plug, filter, rinse, put back. The pressure will return. After 3 years, I decided to see the condition of the heat exchanger, because the water is hard, and, at the last column (Neva), the scale was large flakes inside the copper pipes. Disassembled in 10 minutes - nothing complicated. Very little scale was found in the heat exchanger, less than 1 mm. I washed it a couple of times with anti-scale. Then he rinsed with a shower. Assembled - like new. Who wants to buy - I recommend!

Advantages: Simple design, easily removable connections, quiet operation, inclusion in low water, compactness and much more

Disadvantages: Not detected

Comment: I put this column thanks to reviews on the Yandex market instead of Vaillant AtmoMAG exclusiv 14-0 GRX, which worked for 6 years and died (I didn't pick it, but it broke often and ruble-intensive). I chose it for reasons of ease of operation, a minimum of incomprehensible electronics, climbed in and fixed it myself in 15 minutes. As a result, I am not disappointed and pleased with the choice of BOSCH. The column is so easy to maintain that it is really possible to completely disassemble and assemble it in half an hour, taking into account the cleaning of all units from dust. Thanks to the video from the site http://www.youtube.com/user/teplotehnikaspb I studied this column and a lot about the design and operation of these units .. I realized that I needed to immediately additionally lubricate the stem of the water unit with grease, and also follow and, as often as possible clean the heat exchanger and then the column should serve for a very long time.

Advantages: low price relative to other models, not bad performance

Disadvantages: the only and HUGE MINUS: a weak heat exchanger, enough for 3-5 years, after which it starts to leak. The third column flies, changed at myself and at my parents.

Comment:

Advantages: Heats water well, compact, lightweight, easy to install, no need to constantly adjust - my wick burned all the time, although someone turns it off at night.

Disadvantages: He began to undermine the heat exchanger in three places 3 years after the purchase. I wanted to solder it myself, but the leak is in the junction between the radiator cells, you can't crawl. While I substituted the mug, it does not drip very much.

Comment: Within three years from the moment of purchase, it worked perfectly, was not serviced, the wick burned constantly, as soon as the tap was opened, hot water flowed almost immediately.Now I turn off the wick and turn off the water inlet tap, otherwise it continues to drip even when it is off.If the leak increases, I will buy exactly the same new one - there is nothing more optimal for this money (8 thousand) on the market. Probably again for 3 years - the Boshevsk heat exchangers of our water do not last longer. Yes, and other manufacturers, the same neva - the same trouble with exchangers.

Advantages: -Cost (took over 7200r.) -Stable operation -Good water heating even at 2 points (bathroom, kitchen) -Very very quiet -Compact -Laconic design -The name of the manufacturer inspires confidence (I try to buy household appliances only from this company)

Disadvantages: -The water supply is not done very well. We need to buy an American corner.

Comment: -Use hoses of the correct diameter and you will have excellent water heating and stable performance. Gas - 3/4 Water - 1/2 "Giants". It's just 1/2 too thin. -And do not adjust the water temperature with a tap (mixer). This could overheat the column heat exchanger. Immediately set the required temperature and pressure on the column itself. -I installed it myself.

Advantages: Quiet Compact Reliable Operates at reduced water pressure

Disadvantages: Not yet discovered

Comment: A column in a private house has replaced the old Soviet one, takes up less space, does not require attention at all - once I adjusted the power / volume of water and forgot about it. Due to the low water pressure, the power turned out to be at a minimum (as at the igniter), the volume of water was almost at a minimum, as a result I wash in the shower without problems. During installation, it turned out that the gas pressure in the supply line is almost twice (!) Higher than the standard according to GOST. Therefore, it was necessary to put a gas pressure stabilizer in front of the column (1 thousand rubles). Without it, the flame, even at the minimum power, was as high as the heat exchanger, which is fraught with its burning out, and, accordingly, a quick failure of the column.

Advantages: Simple, reliable. Bosch WR 10-2P performs its functions 100%

Disadvantages: As always, Bosch WR 10-2P has a problem with the water unit (on our water). And if in many other columns (eg Demrad, Rossiyanka, etc.) everything is solved by replacing the oil seal or the top cover, then at least the cover will have to be changed, or even the entire assembly. In my particular specimen, piezo ignition does not work, but this is a special case.

Comment: Actually, I'm an expert (in the past) in ... including speakers. I have known this model since the time when it was still Junkers WR 10-2P (circa 2005), worked in a company that sold, installed and repaired, incl. and speakers Bosch (Junkers). In Bosch WR 10-2P: -two gas sets- installed for natural gas and in stock for propane-butane; - practically no electronics except for: a thermoelement for flame control, overheating protection and a reverse draft sensor; - ignition is piezoelectric and it does not work for me))); - a slide regulator is installed on the gas block (which is worse than a rotary one, but it is quite reliable), which does not have a large enough control range (more or less); - temperature regulation (more-less) is carried out mainly by turning the handle of the water block; - automatic regulation, i.e. maintenance of the set water temperature is indirect (according to the water pressure drop), due to the device of the water block and its interaction with the gas block; the heat exchanger is reliable enough. During installation, do not remove the water filter in any case; moreover, it is advisable to install an additional filter in front of the column, if there is one at the entrance to the house or apartment, then it is not necessary. Service department in the Tula region. well established, incl. at the expense of several competing firms.In general, Bosch repair service is one of the best in Russia (I no longer work, I have the right to praise). In terms of reliability and quality, this column can be compared with Mora and Vailant, but the latter are much more expensive, besides, Vailant has no all-Russian service. The simplicity of repair can be compared with Demrad - the latter is simpler and cheaper to repair, but not so convenient in operation. I always recommended piezo ignition, but it doesn't work in my column))). Usually electric ignition fails more often (knots burn). I would give 4 points for piezo ignition, but I know the column is not on one copy, therefore 5.

Advantages: Bosch is the country of manufacture Portugal, the build quality is at the highest level, almost silent, lightweight, compact, looks stylish compared to analogues, not expensive.

Disadvantages: Not detected for at least a month of use.

Comment: I advise everyone, before it was Neva 4513 worked for five years, but the difference is how, after a domestic car, change to a foreign business class car, in general I recommend, I have not seen a quieter column yet.
