I consider my choice of the Bosch W 10KB model to be quite reasonable, since such a speaker meets all modern requirements.
I can list its main advantages, these include: 1 high-quality assembly (Portugal) 2 simple intuitive control 3 ergonomic design 4 compact dimensions (looks harmonious in our small Khrushchev kitchen) 5 silent operation (in standby mode there is complete silence, and during operation you can hear the ignition turning on) GOLUBENOK

Not worth the money).
I worked for 4 and a half years, which is not enough for Bosch. There are no spare parts for free sale. Expensive service. I do not recommend buying a Bosch WR 13–2P (GWH 13–2CO P) water heater! IraMax

A high-quality gas instantaneous water heater - BOSCH wr 10-2p, I have been using it for 5 years, there have not been a single breakdown during the entire period of operation.
The only thing I had to do was clean the igniter tube from accumulated dust, because... The igniter did not turn on. But this is all easy to do at home. Vlad i mir

We changed the column about 3 years ago, took a long time to choose and came to the conclusion that we should buy it in specialized offices, and not in stores with household appliances.
We bought a “Gas water heater BOSCH WR 13G”, manufactured by JUNKERS Bosch Gruppe Germany. It cost 10,200 rubles then, but there were cheaper ones depending on the functions. This one ignites under the pressure of water, but there are those with a wick that burns all the time, like on our old speakers. The technician who installed it said that it was the best choice among household ones :) Maybe, of course, he tells everyone that, but we are happy so far. Lirin

Bosch geyser: review of models and prices
Thanks to a wide range of functions and high quality, the Bosch geyser is very popular all over the world. Using this unit, you can create an autonomous hot water supply in an apartment, private cottage or country house. There is a large abundance of models of this brand on the market, among which a simple buyer may get confused and buy a Bosch gas water heater that is not suitable for certain conditions. To avoid such a situation, you should study in detail the operating principle of water heaters, characteristics and types.
Typical breakdowns
Most often, Bosch Group owners encounter the following equipment malfunctions:
- The pilot light goes out or the main engine does not turn on on the first attempt to ignite . In this case, you need to clean the ignition burner of the device.
- The wick goes out or the igniter goes out when the user turns the tap on the mixer. Check the gas pressure reducer if the work is carried out on liquefied gas (in cylinders).
- The water does not warm up well enough . The thermostat may be set incorrectly.
- From time to time the pilot light goes out . Most likely, the traction sensor or temperature sensor is triggered. The elimination of these breakdowns should be entrusted to a specialist.
- Insufficient water pressure through the main body . The heat exchanger, water unit, or the mixer itself could be clogged. It is worth identifying the blockage and cleaning it.
- The main battery does not light up . If the battery-powered igniter does not light, replace the batteries.
You will learn how to light the column and the reasons for the failure in a separate article.

General design diagram
Water heaters are available in two types:
- Atmospheric. Devices whose combustion chamber is open, air enters through the inspection compartment on the front panel and the opening at the bottom of the housing. This is the design of the old gas installation (for example, gas water heater Neva 3208, gas water heater Neva 4513, Neva Transit VPG 10 e, etc.).
- Turbocharged. The combustion chamber is closed, air is supplied by a fan, which is why such devices are also called supercharged.
Atmospheric devices are structurally composed of the following elements:
- External metal casing;
- Igniter;
- Manual gas burner;
- Heat exchanger with finned plates, covered with a casing;
- Copper coil located around the heat exchanger;
- Automatic gas supply valve with intensity regulator;
- Water reducer (or water unit) with safety valve;
- Piezo ignition system for a gas water heater;
- Combustion product removal system, chimney;
- Branch pipes for supplying cold water, gas, and discharging hot water together with connecting fittings.
A turbocharged water heater is designed in a similar way with several distinctive features:
- The burner is stepped, modulating, which automatically changes the flame strength;
- Air is supplied by a fan controlled by an electronic control unit;
- Automatic ignition system, which is supplied with energy by the electrical network, hydro generator, batteries;
- A temperature sensor is installed that controls the level of water heating, which should not exceed the established maximum (60⁰-70⁰ C depending on the model).
Operating instructions for Bosch geysers
2017-03-07 Evgeniy Fomenko
The Bosch wr 10 2p geyser can operate from both natural and liquefied gas, i.e. balloon. Equipped with triple protection: a thermoelement for controlling the ignition flame, controlling the draft of gas combustion products, and a temperature limiter that protects the column from overheating.
The model is also equipped with a reliable flame modulation system. This means that the column automatically adjusts the heating to the required liquid flow. If you are washing dishes in the kitchen, and someone decides to wash in the shower, the water temperature will be the same, both in the kitchen and in the shower. The power of the liquid at the outlet is also automatically adjusted when the water pressure in the water supply system changes.
Before turning it on, according to the operating instructions for the Bosch geyser, you must make sure that there is draft in the chimney. This can be done by holding a lit candle or match to the chimney. If the flame deviates towards the chimney, it means that everything is in order with the draft, and you can turn on the device.
If there is no draft, you should find out the reason and clean the air duct, or seal the seams of the air duct pipes if a loose fit of its parts is detected. When the speaker is operating, make sure that the window or window is slightly open; the door in the room where the speaker is installed should not be tightly closed.
This ensures natural air movement and oxygen flow; the unit burns a large amount of oxygen during operation. Failure to comply with these requirements may result in carbon monoxide poisoning. It should also be remembered that when the column is running, you cannot turn on the fan or air conditioner, this will disrupt the flow of carbon monoxide through the chimney.
On the front panel of the device there is a slider on the left that regulates the power, on the right there is a toggle switch for regulating the liquid volume, and above them there is an observation window. Never get too close to it to avoid getting burned.

If starting up for the first time or after a long period of inactivity, some air may accumulate in the column pipes. To remove it, open and close the hot water tap several times, at intervals of about a minute, until it is completely removed.
When you turn it on for the first time, open the gas and water valves and turn on the hot water tap to make sure that liquid is flowing.
The Bosch speaker has a piezo ignition system, the button of which is located at the bottom left. To turn it on, you need to move the slider from the left extreme position to the ignition position, indicated by an asterisk. Press it down and simultaneously press the piezo ignition button several times until the pilot flame appears.
At the same time, loud clicks are heard, you should not be afraid of them, this is how it should be. If the pilot flame ignites, release the slider button; if ignition does not occur, repeat the entire procedure again. The unit may not start if, after a long period of inactivity or when turned on for the first time, air gets into the gas pipes. To remove it, hold the slider button depressed until all the air is removed.
As soon as the unit is turned on, set the power you need using the same slider. The extreme right position provides maximum power, while gas consumption also increases. Using the round knob, the required fluid flow and temperature are set.
By turning the knob clockwise, you reduce the flow and increase the temperature, turning counterclockwise - on the contrary, the flow increases, the temperature decreases. Setting a high temperature increases gas consumption and scale formation in the heat exchanger.
The pilot flame burns continuously, and the main burner ignites when the hot water tap is opened. The shutdown occurs when you close the hot water tap. To completely turn off the unit, you need to move the power regulator slider to the extreme left position, the pilot flame will go out.
If there is a risk of water freezing in the appliance, for example, in a country house in winter, you should completely drain the water from it. To do this, you need to close the water and gas supply valves and open the taps on the mixer.
Remove the housing casing by unscrewing several bolts to gain access to the water unit. Remove the bracket in the shape of the letter “P” from the filter housing on the water fittings and remove the plug, which is located immediately behind the bracket. Wait a while until the liquid is completely drained.
To extend the service life of the device, it is necessary to carry out regular maintenance, at least once a year. Clean the inside of the column from dust and soot, and descale the heat exchanger. At the same time, you should know that all work on gas equipment should only be carried out by a specialist.
After all work has been carried out to prepare the Bosch Gaz 6000 boiler for launch, after pre-launch preparation, which includes checking the expansion tank, shut-off valves, filters, checking the pressure in the gas line, the tightness of all joints, the boiler is connected to the electrical network.
After powering up the power supply, the “attention” icon appears on the electronic display located on the front panel of the unit. Next, press the power button on the front panel, located near the upper left corner of the electronic display. Above the display there is a magnetic instruction manual that allows you to easily change the unit settings.
When turned on, within two seconds, the boiler electronics conduct self-diagnosis, check all sensors and switch to blocking mode. The display shows the current temperature and status code. Next, it is necessary to adapt the fan speed to the length of the chimney to which the unit is connected.
This operation is performed by simultaneously pressing and holding three buttons - “+”, “-” and “back”. The mode is set in accordance with the parameter specified in the instructions for the device - set the second service level, confirm the action with the “ok” button, holding it down until square brackets appear on the display.
Operating principle
The operation of gas equipment is carried out according to the following algorithm:
- after opening the tap, the required coolant enters the heat exchanger, the heating burner is ignited by the igniter;
- water passes through the coil and is heated with the help of heat, which is released in large volumes during fuel combustion (rapid heating occurs due to heat transfer at high speed, which is associated with the high thermal conductivity of materials);
- exhaust gases exit under the influence of natural draft in the chimney or forced exhaust.
