Geyser Bosch instruction manual. How to turn on the BOSCH gas water heater? Disadvantages of Bosch gas water heaters

Consider the example of Bosch WR10.B, WR13.B, WR15.B gas instantaneous water heater models made in Germany, for the markets of Russia, Ukraine, Belarus. These models differ in the amount of heated water.

Bosch WR10.B, WR13.B, WR15.B

Before starting, check if the gas and water valves are open, if two 1.5 V R batteries are inserted. These models of heaters are equipped with electric ignition, as evidenced by the index B at the end of the name. Electric ignition takes place using batteries.

To turn on the device, you need to press the power button on the front panel of the device, the column is prepared for operation, is in standby mode. In order for the heated water to go, you just need to open the tap. At this point, the pilot flame is ignited and after four seconds the main flame is ignited, so that the pilot flame is extinguished after approximately twenty seconds.

These devices do not have a constantly burning wick, which is economical as there is no constant gas flow. During a long break in work gas system air can accumulate, which will prevent correct work igniter and, as a result, the main burner cannot ignite.

To fix this problem, you need to open and close the tap hot water repeatedly. Water heating is regulated by reducing its flow, by turning the valve clockwise it decreases, counterclockwise, respectively, vice versa, the flow increases and the temperature decreases. At a low water temperature, gas costs are reduced and less scale is formed in the heat exchanger.

On the video, in addition to the startup procedure, you can also learn about setting up the column:

How to light a gas water heater bosch Therm 4000 O WR 10/13/15 -2 P.

The difference between these models lies in the amount of heated water per minute. A device equipped with piezo ignition is indicated by the letter P at the end of the name. It has the ability to adjust two parameters, water and combustion power. To turn on the column, you must move the slider to the ignition position, drown it.

Press the piezo ignition button several times until a flame appears on the pilot burner. Wait ten seconds, release the slider and move it to the desired power position. Moving the slider to the right increases power, and to the left decreases it. The column is in standby mode all the time, if you need to get hot water, you just need to open the valve with hot water.

When you need to turn off, move the slider to the left until it stops. After a couple of seconds, the pilot flame will go out. Close the gas valve and water valves.

Watch the video below for instructions on how to turn it on:

Therm 4000 S WTD 12/15/18 AM E23/31.

Before starting, you must make sure that, on the plate installed by the manufacturer on the device, the gas marking corresponds to the gas connected to the device. It is possible to connect a remote control to the device, which completely duplicates the operation of the display on the column.

Open the gas cock and water valves. Connect the machine to the mains.

The water temperature set by the manufacturer is 42 degrees, this is the optimum temperature.

To turn on the device, you just need to press the power button and open the hot water tap. To control the temperature, you must press the "+" or "-" button and select the temperature you need. Until the temperature you have selected is reached, the reading on the monitor will flash.

If it does not reach this value within thirty seconds, the icon will be displayed on the monitor. faucet, which indicates the need to increase or decrease the flow of water. If you press the P button, the programmed constant temperature of 42 degrees will appear. Setting the minimum temperature reduces energy consumption, and makes it possible to reduce the formation limescale in the heat exchanger.

But if you know how to turn on the column, but encounter malfunctions (the flame goes out, does not ignite), then where the causes and methods for their elimination are described.

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 great abundance of models of this brand on the market, among which a simple buyer can get confused and buy a Bosch geyser that is not suitable for certain conditions. To avoid such a situation, you should study in detail the principle of operation of water heaters, characteristics and varieties.

Rating of the best models of geysers Bosch

The official website of the company provides a wide range of geysers Bosch, thanks to which each consumer will be able to choose an option for himself in terms of cost and technical characteristics. Each classification differs in the type of ignition, power and performance, but they are all made in two main shades:

  • white;
  • grey.

Modifications are made at the Portuguese factory, but Bosch devices can be purchased in Moscow, St. Petersburg and in any other city through official representatives. There is a separate series of geysers, which is assembled in China, in fact, it is the most budget option. Let us consider in more detail which versions of devices are supplied to the domestic market.

Bosch 2000-O THERM

This line is considered the cheapest, since it has a relatively low productivity of up to 10 l / min. and involves working in combination with one water intake point.

Water heaters have a battery-powered ignition system, a tubular-type heat exchanger, consisting of copper material and a steel burner. The units have a controller for the degree of thrust and the level of the flame. The devices are also equipped with a sensor temperature regime liquid and gas flow. This version includes the Bosch W 10 KB device with compact dimensional parameters and an estimated cost of 8,000 rubles.

Bosch 4000-O THERM

The most demanded series of geysers Bosch, which is produced with automatic method ignition or piezo ignition. In the first case, water heaters operate on batteries and require regular replacement of the voltage source, the second option requires constant pressing of the key to start work. 3 varieties are supplied to the market, with different power indicators and performance levels - 10-15 l / min.

BOSCH WR 10-2 R23

The units have a heat exchanger consisting of a copper material, due to which the device has an increased service life of up to 15 years. In addition to all modifications, they are equipped with a smooth modulation of the burner fire, thanks to which the device is able to independently maintain the specified temperature regime even with pressure surges.

One of the most important advantages is the possibility of functioning at water pressure in plumbing system at 0.1 atm.

This classification includes the following models:

  • modifications of the machine with the prefix "B" - WR10 2V, 13 2V, 15 2V;
  • semiautomatic device with the prefix "P", indicating the presence of a piezo ignition - gas water heater Bosch WR 102P, 13 2P, 15 2P.

Each option has an individual column ignition method. In the first case, ignition is carried out without the user's participation when the water tap is opened, in the second case, you need to set fire to the wick in the device by simply pressing the desired key.

Water heaters with piezo ignition are significantly cheaper than electric ignition devices, but each of the options has its drawbacks - the need to replace batteries, the inconvenience of turning on the column at arm's length, etc.

Bosch 4000-S THERM

The main distinguishing characteristic of the devices of this series is the presence in the design of a fan that creates forced draft. The devices are able to function without a chimney system, so there is no need for special maintenance. Such units are especially relevant for apartment owners in which it is not possible to equip a chimney.

Therm 4000 S WTD 12AM E23

Output of combustion products and supply fresh air carried out at the expense coaxial chimney. This element must be installed horizontally through the wall directly to the street. It is sold as an additional option and, as a rule, is supplied separately from the geyser.

Also in the units there is a digital display for determining error codes, setting the temperature regime and other programs. This device, thanks to the burner fire modulation device, can maintain the set mode with an error of up to 1 ° C.

The line includes the following models:

  • WTD 12AM E-23;
  • 15AM E-23;
  • 18AM E-23.

From this it becomes clear that modifications are made in three versions in terms of power and heating intensity of 12-18 l / min. They have a drawback - the devices are powered by 220 V, so the models are considered completely volatile.

Bosch 6000-O THERM

Bosch 10 2G, WRD 13 2G, 15 2G devices are equipped with a hydrogenerator and automatic ignition of the burner, which is carried out by means of a water flow. When the tap is opened, the liquid circulates into the column, and the Hydro Power system automatically starts the device with a hydrodynamic generator. In this case, batteries or a piezoelectric element are not required.

Therm 6000 WRD 10 2G

As for the heating efficiency, it is 10-15 l / min., Depending on the modification. The control panel is equipped with a liquid crystal screen, which displays all information about the operation of the device.

Geyser Bosch 6 000-S, 8 000-S THERM

These series are considered industrial because they are capable of producing 24 and 27 l / min. and work on 4 mixers. Geysers have electric ignition and a liquid crystal screen on the front of the panel.

THERM 8000 WTD 27 AME

In the first case, the units are equipped with two fans, in the second - with a special condensation device and an electric drive.

Frequent problems

Each consumer should be aware of the problems that he may encounter when operating a Bosch geyser. Regardless of which W10 KB or WRD 13 2G model it is, where it was purchased and at what price, the following situations may occur during use:

  1. The water heater does not ignite or the fire goes out a few seconds after starting. Ignition burner needs to be cleaned.
  2. The wick goes out when the water collection starts. The fuel pressure regulator needs to be checked. This must be done if the device operates on bottled fuel.
  3. The liquid warms up insufficiently or does not change the initial temperature at all. It is necessary to examine whether the temperature control knob, which is located on the front of the control panel, is set correctly.
  4. The igniter goes out for no reason. Probably, the controller of the degree of traction or the temperature regime of the water is turned on. This will require the intervention of a Bosch gas column repairman.
  5. The pressure of the water leaving the column has decreased. The cause of the problem is the contamination of the heat exchanger, tap, water unit. It is necessary to identify the source and clean it up.
  6. Water heater with automatic system does not start. The batteries may be dead or damaged, you need to replace them with new ones.

VIDEO: How to choose Bosch water heaters - what's the difference

2017-03-07 Evgeny Fomenko

The Bosch wr 10 2p geyser can operate on both natural and liquefied gas, i.e. balloon. It is 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 reliable system flame modulation. This means that the column automatically adjusts the heating to the required fluid 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 regulated when the water pressure in the water supply changes.

Before turning on, according to the operating instructions for the Bosch geyser, you need to make sure that there is draft in the chimney. this can be done by bringing a lit candle or match to the chimney. If the flame deviates towards the chimney, then everything is in order with the draft, and the device can be turned on.

If there is no draft, you should find out the cause and clean the air duct, or seal the seams of the air duct pipes if a loose fit of its parts is found. When the column is operating, make sure that the window or window is ajar, the door in the room where the column is installed should not close tightly.

This ensures the natural movement of air and the flow of oxygen, the unit burns during operation a large number of oxygen. Failure to comply with these requirements may result in poisoning. carbon monoxide. It should also be remembered that when the column is running, you cannot turn on the fan or air conditioner, this disrupts the outflow of carbon monoxide through the chimney.

On the front panel of the apparatus, on the left, there is a slider that regulates the power, on the right, a toggle switch for the volume of liquid, above them there is a viewing window. Never get too close to it to avoid burns.

Gas column control panel Bosch WR 13-2 P

If starting for the first time or after a long period of inactivity, some air may accumulate in the dispenser 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 first turned on, open the gas and water supply valves, open the hot water tap to make sure that the liquid flows.

The Bosch column 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. Drown it and at the same time press the piezo ignition button several times until the ignition flame appears.

At the same time, loud clicks are heard, they should not be scared, as 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 first turned on in gas pipes air got in. To remove it, hold the slider button in a recessed state until all air is removed.

Once the unit has turned on, set the power you need using the same slider. The extreme right position provides maximum power, while increasing gas consumption. With the help of a round knob, the required flow of liquid and its temperature are set.


By turning the knob clockwise, you reduce the flow and increase the temperature, by turning it counterclockwise, on the contrary, the flow increases, the temperature decreases. Installation high temperature increases gas consumption and scale formation in the heat exchanger.

The pilot flame burns constantly, and the main burner ignites at the moment the hot water tap is opened. The shutdown occurs when you turn off the hot water tap. To turn off the unit completely, move the power regulator slider to the extreme left position, the ignition flame will go out ...

If there is a risk of water freezing in the appliance, e.g. in a country house in winter period must be completely drained of water. To do this, close the water and gas supply valves, open the taps on the mixer.

Remove the housing cover by unscrewing a few bolts to access the water unit. Remove the bracket in the form of the letter “P” from the filter housing on the water fitting and remove the plug, which is located immediately behind the bracket. Wait a while until the liquid is completely drained.

To prolong the life of the device, it is necessary to carry out regular maintenance, at least once a year. Clean off dust and soot inner part columns, rinse the heat exchanger from scale. It should be known, however, that all work with gas equipment should only be done by a specialist.


After carrying out all the work to prepare the Bosch Gaz 6000 boiler for launch, after pre-launch preparation, which includes checking expansion tank, stop valves, filters, checking the pressure in the gas line, the tightness of the connection of all joints, the boiler is connected to the electrical network.

After powering up to the mains, the “attention” icon appears on the electronic display, which is 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 is a magnetic instruction that allows you to easily change the settings of the unit.

When turned on, within two seconds, the boiler electronics performs self-diagnostics, all sensors are checked and switched 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 - we set the second service level, confirm the action with the "ok" button, holding it until square brackets appear on the display.

In addition to the display, in the lower right part, a pressure gauge is mounted showing the pressure in the system, normal pressure is in the green zone. The red zone indicates the pressure below and above the nominal pressure when the protection is activated and the unit is turned off.

Bosch THERM 4000

You can increase the pressure using the blue tap by unscrewing it counterclockwise until the pressure gauge needle returns to the blue zone. When the pressure increases, the liquid will be discharged through the corrugated tube at the bottom of the unit and the pressure gauge will return to its normal position.

The boiler can operate in two modes, liquid heating and heating mode, which of the modes is active, shows the icon on the display.

The mode is selected by pressing the "+" or "mode" button. Having selected the mode, set the desired temperature, then press "ok" - confirm the choice, after which the up and down arrows appear on the display, use the "+" and "-" buttons to set the required heating temperature. To save the selection, press the OK button and hold for a couple of seconds.

If it is necessary to set the heating operating mode, select it with the “-” button, confirm by pressing “OK”. The choice of temperature and saving the choice is carried out in the same way as when setting the water heating temperature. The fire icon that appears on the display indicates that the turbine has turned on and heating has begun.

When the set temperature is reached, the fire icon will disappear, after falling, when the boiler turns on again, it will appear again, this will happen cyclically throughout the entire operation of the boiler with the specified parameters. In the event of any malfunctions in the operation of the Bosch Gaz 6000, for example, in the absence of gas or water supply, the protection will work and an error message will appear on the display.

The interpretation of the error and the actions to eliminate it are described in the instructions for the boiler. After identifying and eliminating the cause, you must confirm the action on the display by pressing and holding the "ok" button for a few seconds. After that, the boiler automatically starts up again.

The unit is protected from freezing if the pump is running and fluid is circulating through heating system. If the boiler needs to be turned off, then antifreeze is added to the heating liquid, and water is drained from the hot water supply, as a rule, this work is done by a specialist. Maintenance is also produced by a specialist, since the unit is a rather complex device associated with high blood pressure and gas.

We offer you to watch a video about the rules for setting up the Bosch 4000 O column:

On the market household appliances it's probably hard to imagine trademark better known than Bosch. The company quite successfully supplies products under its own brand all over the world, ranging from irons, refrigerators and ending with power tools. A separate division is the production of a German concern heating equipment: boilers and water heaters from Bosch-Thermotechnika.

Solid fuel and have been heating houses for many years, both in Russia and abroad.
Russian consumers are especially popular Bosch geysers, reviews of which can often be seen on specialized sites. Customers are attracted by the quality and reliability affordable price for instantaneous water heaters from a German manufacturer.

Let's figure it out together whether it is worth buying a Bosch geyser today, given such a wide choice of manufacturers in our time. For this, it is necessary to consider the lineup, prices and specifications device from a German concern, disadvantages and advantages compared to its direct competitors in the market.

Let's make a short review of Bosch geysers based on the operating instructions, as well as reviews from experts and customers. Let's analyze the main malfunctions of the Bosch column: why the igniter does not light up or the wick goes out, etc.

Model range and features of Bosch geysers

Bosch geysers, unlike their direct competitor, have a very wide range of models. Lots of modifications from different type ignition and performance, design and size. Water heaters are found in two colors: white and gray.

Geysers Bosch: model range


All gas instantaneous water heaters are assembled in Portugal, the difference is only one, the most budgetary model of columns - "Therm 2000 O", type W10 KB, which is assembled in China. Now let's look at all the models and series that are supplied to the Russian market.

1. Series Therm 2000O

This is a budget geyser with a small hot water capacity of 10 l / min. This machine is equipped with automatic battery ignition, tubular copper heat exchanger and gas burner from stainless steel.

As in the columns, it contains an emergency draft and flame control sensor, as well as a water temperature sensor and a gas control system. The Bosch W10 KB column has a compact size, and you can buy it inexpensively, from 8,000 rubles.

2. Series Therm 4000O

Most popular models are produced both with automatic ignition from batteries, and with piezo ignition by pressing a special button. Three types of different capacities and capacities from 10 to 15 l/min are available. Bosch geysers of this series have a high-quality copper heat exchanger for heating running water with extended service life up to 15 years.

Also, these models are equipped with a smooth modulation of the burner flame, with the help of which the device itself maintains the set outlet water temperature. An important advantage of this model is that this column turns on at a water pressure of only 0.1 atmospheres.

Flowing gas water heaters of this series have the following designation:

- Bosch column with automatic ignition (the article "B" is present): WR 10-2B, WR 13-2B and WR 15-2B;

- Bosch semi-automatic column with piezo ignition (marked with the symbol "P"): WR 10-2P, WR 13-2P, WR 15-2P.

Bosch column with piezo ignition


3. Series Therm 4000S

The main feature of this model is the presence of a fan for forced draft. These columns can work without a chimney, i.e. no special construction is required. This feature is very convenient when it is not possible to install a chimney in an apartment or house.

The emission of combustion products and the flow of air into the geyser is carried out thanks to a special one, which is installed horizontally through the wall to the street. This kit is an option and is supplied separately from the device itself.

Another important feature of the Bosch AM1E series gas water heaters is the presence of a digital control panel, which displays possible mistakes in case of device failure. You can also set the water temperature and, thanks to even smoother and more precise modulation of the burner flame than the previous model, this water heater will maintain the temperature with an error of only 1 ° C.

The model is issued with three types of power, with a productivity from 12 to 18 l/min. Unlike other models, this series of devices is volatile due to the built-in fan powered by 220 V. They are marked as WTD 12 AM E23, WTD 15 AM E23 and WTD 18 AM E23, depending on their rated power.

4. Series Therm 6000O

The Bosch geyser of the six hundredth series is equipped with a built-in hydrogenerator. Automatic ignition in this model is carried out due to the flow of water through the column. When the tap is opened, water enters the water heater, and HYDRO POWER technology automatically turns on the gas water heater through a special hydrodynamic generator.

To ignite the device, neither a piezoelectric element nor batteries (batteries) are required. Available in different capacities: 10, 13 and 15 liters per minute. They have the abbreviation WRD 10-2G, WRD 13-2G, WRD 15-2G, the numbers show the performance.

The control panel has a small LCD display that only displays the water temperature. This parameter is set using mechanical regulator on the front side speakers and supported by the unit automatically.

5. Series Therm 6000S and 8000S

These are industrial models of geysers from a German concern. Productivity of water heaters of these series makes 24 and 27 l/min, respectively. These columns are capable of supplying hot water to 4-5 taps at the same time. Bosch water heaters are equipped with electric ignition and an informative LCD display on the front side.

Model 6000 S series has two built-in fans for removal of combustion products and air suction. Bosch water heater 8000 S thanks to special technology condensation has an increased efficiency of water heating. Besides, the water valve of this model is supplied with the electric drive.

The principle of operation of a Bosch gas column with piezo ignition is quite simple. We set the water temperature regulator to the “On” position, press the button of this regulator, simultaneously pressing the piezo ignition button from below. Hold the thermostat button until the column turns on. They also set the desired water temperature.

The principle of ignition of a geyser with automatic ignition is even simpler. We open the tap with hot water on the mixer, and the column turns on by itself, thanks to the batteries pre-installed in the device. At gas water heaters Bosch they come with a column. The igniter for devices with piezo ignition burns constantly, and for automatic speakers, it fades when the device is turned off.

Technical characteristics of geysers Bosch WR series

Water heaters from a German manufacturer can operate both on natural and on liquefied gas. The diameter of the pipe for supplying gas is 3/4 inch, water - 1/2. The diameter of the chimney pipe varies, and depending on the specific model, it ranges from 115 mm to 135 mm. Other options can be seen in this table.
