Gas water heaters Bosch (this is the household name that the instantaneous water heater received) - a device in which cold water flowing through the tubes around the heated heat exchanger heats up and goes to the consumer with a predetermined comfortable temperature. Bosch geysers heat water using the energy obtained from the combustion of gas.

At the end of the 19th century, the designers of the Bosch concern first designed a gas water heater. The device has undergone numerous upgrades over time and nowadays represents fully automated products, which are still in demand in households where, for a number of reasons, there is no centralized supply hot water.

Today, instantaneous water heaters are produced by companies around the world, and Bosch is rightfully considered the leader in the production of these products. The Bosch concern offers the consumer the widest range of devices with various power characteristics that can satisfy all the needs of the homeowner in heating the required volume of liquid.

Modern Bosch gas water heaters are capable of heating water online. The owner does not need to waste time waiting for the required amount of water to warm up. Instantaneous water heater stuffed with all kinds of sensors and valves that allow you to get a comfortable temperature at the point of draw-off. Bosch geysers, regardless of the model, are equipped with power modulation.

Thus, with an increase in the draw-off, the heating intensity automatically increases. If the consumer reduces the pressure by closing the tap, then the burner automatically reduces the flame, reducing the intensity of work. The main advantage that unites Bosch gas water heaters is energy efficiency and economy, which translate into significant financial savings in the form of gas bills.

Before we begin an overview of the Bosch instantaneous water heater, we suggest that you decide on the necessary device parameters that are right for you. There is no need to buy a Bosch gas water heater with a “margin” in power, this will only lead to high initial costs and subsequent gas overruns and, as a result, financial resources.

Let us consider on the example of models of gas instantaneous water heaters Bosch WR10.B, WR13.B, WR15.B manufactured 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 R-type batteries of 1.5 V are inserted. These heater models are equipped with an electric ignition, as indicated by the B index at the end of the name. Electric ignition occurs with batteries.

To turn on the device, you need to press the power button on the front panel of the device, the speaker is ready for work, it is in standby mode. In order for the heated water to flow, you just need to open the tap. At this point, the pilot flame ignites and after four seconds the main flame is ignited, thus the pilot flame extinguishes after approximately twenty seconds.

These devices do not have a constantly burning wick, which is economical as there is no constant flow gas. With a long break in work in gas system air can accumulate, which will interfere with the correct operation of the igniter and, as a result, will not be able to ignite the main burner.

To eliminate this problem, it is required to open and close the hot water tap several times. Water heating is regulated by reducing its flow, by turning the valve clockwise it decreases, counterclockwise, respectively, on the contrary, the flow increases and the temperature decreases. At low water temperatures, gas consumption is reduced and less scale is formed in the heat exchanger.

In the video, in addition to the startup procedure, you can also learn about the speaker setup:

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 a piezo ignition is indicated by the letter P at the end of the name. It has the ability to regulate two parameters, water and combustion power. To turn on the column, you need to move the slider to the ignition position, drown it.

Press the piezo ignition button several times until a flame appears on the ignition burner. Wait ten seconds, release the slider and move it to the desired power position. Moving the slider to the right increases the power and decreases it to the left. 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 taps.

In the video below, see the instructions for turning 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. The device has the ability to connect a remote control, which completely duplicates the display on the speaker.

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

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

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

If it does not reach this value within thirty seconds, the water tap icon is displayed on the monitor, which indicates the need to increase or decrease the water consumption. 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 are faced with malfunctions (the flame goes out, does not light up), then where are the causes and methods of their elimination described.

On the market household appliances it’s probably hard to imagine a brand better known than Bosch. The company has been quite successful in supplying products under its 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-Thermotekhnika".

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 the bottom. We hold the thermostat button until the column is turned on. We also set the required water temperature.

The principle of ignition of a gas water heater 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. Have gas water heaters Bosch they come complete with a column. The igniter for devices with piezo ignition burns constantly, and for automatic speakers it dies out when the device is turned off.

Technical characteristics of geysers Bosch WR series

Water heaters from a German manufacturer can operate on both natural and liquefied gas. The diameter of the gas inlet is 3/4 ", and the water is 1/2. The diameter of the chimney pipe is different, and depending on the specific model, it ranges from 115 mm to 135 mm. Other parameters can be seen from this table.

Today we examined the legendary manufacturer of household appliances, in particular, gas water heaters from the German concern. Disassembled in detail all models, series and technical characteristics gas water heaters Bosch... Reviews can be found different, but the columns from this manufacturer undoubtedly occupy one of the first places in the ratings for quality and reliability. Watching the video.

In fact, the only drawback of the devices of this brand is their price: the model of the Portuguese assembly will cost an average of 12-15 thousand rubles. And it's up to you to decide whether to buy a Bosch gas water heater today or not, of course.

2017-03-07 Evgeny Fomenko

The geyser Bosch wr 10 2p can operate both from natural and from liquefied gas, i.e. balloon. Equipped with triple protection: a thermoelement for controlling the ignition flame, controlling the draft of gas combustion products, a temperature limiter that protects the column from overheating.

The model is also equipped with reliable system flame modulation. This means that the column automatically adjusts the heating to the required fluid flow. If you wash the dishes in the kitchen, and someone decided 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 pressure of the water in the water supply system changes.

Before switching on, according to the operating instructions for the Bosch gas water heater, you must make sure that there is a draft in the chimney. this can be done by holding a lighted candle or a match to the chimney. If the flame deflects towards the chimney, then everything is in order with the draft, and you can turn on the device.

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

Thus, the natural movement of air and the flow of oxygen is ensured, the unit burns during operation a large number of oxygen. Failure to comply with these requirements can be poisoned carbon monoxide... It should also be remembered that when the column is running, you cannot turn on a fan or air conditioner, this interferes with the outflow of carbon monoxide gases through the chimney.

On the front panel of the device 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 an observation window. Never get too close to it to avoid burns.

Gas water heater control panel Bosch WR 13-2 P

If the start-up occurs for the first time or after a long idle period, 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 using for the first time, open the gas and water supply valves, open the hot water tap to make sure liquid is flowing in.

The Bosch column has a piezo ignition system, the button of which is located at the bottom left. To enable it, you must move the slider from the left extreme position to the ignition position, indicated by an asterisk. Drown it and simultaneously press the piezo ignition button several times until the ignition flame appears.

At the same time, loud clicks are heard, you should not be afraid of them, it should be so. 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 switched on for the first time, gas pipes got air. To remove it, hold the slider button in a recessed state until all the 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 the gas consumption also increases. With the help of a round knob, the required fluid flow and temperature are set.

By turning the knob clockwise, you decrease the flow and increase the temperature, while 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 when the hot water tap is opened. The shutdown occurs when you turn off the hot water tap. To completely turn off the unit, 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 period, you should completely drain the water from it. For this, it is necessary to close the water and gas supply valves, open the valves 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 "П" 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 prolong the service life of the device, it is necessary to carry out regular maintenance, at least once a year. Clean from dust and soot interior columns, descale the heat exchanger. In this case, you should be aware that all work with gas equipment should only be done by a specialist.

After all the work on preparing the Bosch Gaz 6000 boiler for start-up, after pre-start preparation, which includes a check expansion tank, shut-off valves, filters, checking the pressure in the gas main, the tightness of the connection of all joints, the boiler is connected to the electrical network.

After energizing to the mains on the electronic display, which is located on the front panel of the unit, the "attention" icon appears. Next, press the power button on the front panel, located next to the upper left corner of the electronic display. Above the display is a magnetic instruction allowing easy adjustment of unit settings.

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 a 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 the square brackets appear on the display.

In addition to the display, in the lower right part, there is a pressure gauge that shows the pressure in the system, the normal pressure is in the green zone. The red zone indicates the pressure below and above the nominal, when the protection is activated and the unit shuts down.

Bosch THERM 4000

You can increase the pressure using the blue valve by unscrewing it counterclockwise until the pressure gauge needle returns to the blue zone. As the pressure rises, the fluid is released through the fluted tube at the bottom of the unit and the pressure gauge returns to its normal position.

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

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

If it is necessary to set the heating operation mode, select it with the "-" button, confirm by pressing "ok". The choice of temperature and the saving of the selection is carried out in the same way as when setting the temperature for heating water. 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 a fall, when the boiler turns on again, it will appear again, this will happen cyclically throughout the entire operation of the boiler at the set parameters. In case of any malfunctions in the operation of 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 explanation of the error and the steps 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 will automatically start up again.

The unit is protected against freezing if the pump is running and the liquid circulates 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 performed 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.

Rating of the best models of Bosch gas water heaters

On the official website of the company, a wide assortment of Bosch gas water heaters is provided, 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;
• Gray.

Modifications are made at a Portuguese factory, but you can purchase Bosch devices in Moscow, St. Petersburg and in any other city through official representatives. There is a separate series of gas water heaters that are assembled in China, in fact, it is the most budget option... Let's take a closer look at which versions of devices are supplied to the domestic market.

Bosch 2 000-O THERM

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

Water heaters have a battery ignition system, a tube-type heat exchanger, consisting of copper material and a steel burner. The units have a thrust and flame level controller. Also, the devices were equipped with a sensor temperature regime liquid and gas flow. This version includes a Bosch W 10 KB device with compact dimensions and an approximate cost of 8,000 rubles.

Bosch 4 000-O THERM

The most demanded series of Bosch geysers, which is produced with an automatic ignition method 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 a button to start work. Three varieties are supplied to the market, with different power indicators and performance levels - 10-15 l / min.

BOSCH WR 10-2 P23

The units have a heat exchanger made of copper material, due to which the device has an increased operating life of up to 15 years. In addition to all the 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 pluses the possibility of functioning at a water pressure in the water supply system of 0.1 atm is considered.

V this classification includes the following models:

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

Each option has an individual column ignition method. In the first case, the ignition is carried out without the participation of the user when opening the water intake tap, in the second, you need to light the wick in the device by simply pressing the desired key.

Piezo-fired water heaters are much cheaper than electrically fired devices, but each of the options has its own drawbacks - the need to replace batteries, the inconvenience of turning on the column at a more outstretched arm's distance, etc.

Bosch 4 000-S THERM

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

Therm 4000 S WTD 12 AM E23

Combustion products withdrawal and feeding fresh air carried out at the expense coaxial chimney... This element must be installed horizontally through the wall directly onto the street. It is sold as an additional option and, as a rule, is supplied separately from the gas water heater.

Also, the units have a digital display for determining error codes, setting the temperature regime and other programs. This device, thanks to the modulation device of the burner fire, it can maintain a given 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 12-18 l / min. They have a drawback - the devices operate on a 220 V power supply, so the models are considered completely volatile.

Bosch 6 000-O THERM

Apparatus Bosch 10 2G, WRD 13 2G, 15 2G are equipped with a hydrogenerator and automatic ignition of the burner, which is carried out by means of a stream of water. When the valve 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 piezoelectric element are not required.

Therm 6000 O WRD 10 2G

As for the heating efficiency, it is equal to 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.

Gas water heater Bosch 6 000-S, 8 000-S THERM

These series are considered industrial as they are capable of producing 24 and 27 l / min. and work on 4 mixers. The gas columns are electrically ignited and have a liquid crystal display on the front of the panel.

THERM 8000 S 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 face when using a Bosch gas water heater. Regardless of whether it is a W10 KB or WRD 13 2G model, where it was purchased and at what price, the following situations may arise during use:

1. The water heater does not ignite or the fire goes out a few seconds after starting. The ignition burner needs cleaning.
2. The wick goes out when the water collection starts. It is necessary to check the fuel pressure reducer. This must be done if the device operates on bottled fuel.
3. The liquid does not warm up enough or does not change the initial temperature at all. It is necessary to examine whether the temperature regulator, which is located on the front of the control panel, is correctly set.
4. The igniter goes out for no reason. Probably, the controller of the degree of traction or the temperature of the water turns on. This will require the intervention of a Bosch geyser repairman.
5. The pressure of the water leaving the column has decreased. The cause of the malfunction is the contamination of the heat exchanger, tap, water unit. It is necessary to identify the source and carry out its cleaning.
6. Water heater with automatic system does not start. Perhaps the batteries are dead or damaged, you need to replace them with new ones.
