How to turn on a BOSCH gas water heater? Operating instructions for Bosch geysers Bosch gas water heater instructions for use

Let's look at the example of Bosch gas instantaneous water heaters WR10.B, WR13.B, WR15.B, manufactured in Germany, for the markets of Russia, Ukraine, and Belarus. These models differ in the amount of heated water.

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

Before starting, check that the gas and water valves are open and that two 1.5 V type R batteries are inserted. These heater models are equipped with electric ignition, as indicated by the B index at the end of the name. Electric ignition occurs using 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 operation and is in standby mode. In order for heated water to flow, you just need to open the tap. At this point the pilot flame ignites and four seconds later the main flame ignites, so the pilot flame goes out after approximately twenty seconds.

These devices do not have a constantly burning wick, which is economical since there is no constant gas consumption. During a long break from work in gas system Air may accumulate, which will prevent the igniter from working properly and, as a result, the main burner will not be able to ignite.

To fix this problem you need to open and close the tap hot water repeatedly. Adjustment of water heating occurs 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.

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

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

The difference between these models is the amount of water heated per minute. A device equipped with piezo ignition is designated 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 and press it down.

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 the 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 it off, move the slider all the way to the left. After a couple of seconds, the pilot flame will go out. Shut down gas tap and water taps.

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 on the device by the manufacturer, the gas marking corresponds to the gas connected to the device. The device has the ability to connect a remote control panel, which completely duplicates the operation of the display on the column.

Open the gas valve and water valves. Connect the device to the power supply.

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 hot water tap. To regulate the temperature, you need to press the “+” or “-” button and select the temperature you need. Until your selected temperature is reached, the display will flash.

If it does not reach this value within thirty seconds, the water tap, which indicates the need to increase or decrease water flow. If you press the P button, the programmed constant temperature of 42 degrees will appear. Installation 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 reasons and methods for eliminating them are described.

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 found loose fit its parts. 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, gas pipes air got in. 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 winter period, 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 from dust and soot inner part columns, descale the heat exchanger. However, you should know that all work with 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-start preparation, which includes checking expansion tank, shut-off valves, filters, checking the pressure in the gas main, 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.

In addition to the display, in the lower right part there is a pressure gauge mounted, showing the pressure in the system; normal pressure is in the green zone. The red zone indicates pressure below and above the nominal pressure when the protection is triggered 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. As the pressure increases, 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 mode is active is shown by an 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 up and down arrows appear on the display, use the “+” and “-” buttons to set the required heating temperature. To save the selection, you need to press the “ok” button and hold it for a couple of seconds.

If you need to set the heating operating mode, select it with the “-” button and confirm by pressing “ok”. Selecting the temperature and saving the selection occurs 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 at 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, protection will be activated and an error message will appear on the display.

The explanation of the error and 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 several seconds. After this, the boiler automatically starts up again.

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

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

Thanks to wide range 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.

Rating of the best models of Bosch geysers

The company's official website provides a wide range of Bosch gas water heaters, so every consumer can choose an option for themselves in terms of cost and technical specifications. 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 plant, but you can purchase Bosch devices in Moscow, St. Petersburg and any other city through official representatives. There is a separate series of geysers, which 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 2000-O THERM

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

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

Bosch 4 000-O THERM

The most popular series of Bosch geysers, which is available 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 a key to start operation. There are 3 varieties available on the market, with different power ratings and performance levels - 10-15 l/min.

BOSCH WR 10-2 P23

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

One of the most important advantages is the ability to operate at a water pressure in the plumbing system of 0.1 atm.

This classification includes the following models:

• modifications of the machine with the prefix “B” - WR10 2B, 13 2B, 15 2B;
• semi-automatic 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, ignition is carried out without user intervention when opening the water tap; in the second, you need to light the wick in the device by simply pressing the desired key.

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

Bosch 4 000-S THERM

Main distinguishing characteristic devices of this series, this is the presence in the design of a fan that creates forced draft. The devices can operate without a chimney system, so no special maintenance is required. Such units are especially relevant for apartment owners who do not have the opportunity to install a chimney.

Therm 4000 S WTD 12 AM E23

Exhaust of combustion products and supply fresh air carried out at the expense of 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 gas water heater.

The units also have a digital display for determining error codes, setting the temperature mode and other programs. This device, thanks to the burner fire modulation device, can maintain the specified 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 operate on a 220 V power supply, so the models are considered completely energy-dependent.

VIDEO: Bosch Therm 4000 O geyser (review and setup)

Bosch 6 000-O THERM

The Bosch 10 2G, WRD 13 2G, 15 2G devices are equipped with a hydrogen generator and automatic ignition of the burner, which is produced by a stream of water. 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 in this case no batteries or piezo element required.

Therm 6000 O 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. Gas water heaters have electric ignition and a liquid crystal screen 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 - special device condensation and electric drive.

Frequent problems

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

1. The water heater does not light up or the fire goes out a few seconds after starting. The pilot burner needs to be cleaned.
2. The wick goes out when water collection begins. You need 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. You need to examine whether the temperature regulator, which is located on the front of the control panel, is set correctly.
4. The pilot light goes out for no reason. The traction control or water temperature control probably turns on. This will require the intervention of a Bosch geyser repair technician.
5. The pressure of water coming out of the column has decreased. The cause of the problem is contamination of the heat exchanger, tap, or water unit. It is necessary to identify the source and clean it.
6. Water heater with automatic system won't start. The batteries may be discharged or damaged; they need to be replaced with new ones.

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

Household gas heaters (heaters) are designed to provide consumers with hot water. Based on the switching principle, they are divided into automatic and semi-automatic. In automatic dispensers, it is responsible for igniting gas burners. electrical unit spark generator; in semi-automatic water dispensers, gas burners are ignited from a gas wick every time water is drawn.

In this article we will look at what to do if a gas water heater with a semi-automatic ignition system does not light up, the principle of operation of the ignition system, the causes of malfunction of the gas wick and methods for eliminating them.

Operating principle of a semi-automatic gas water heater ignition system

The ignition system for semi-automatic dispensers consists of:

• gas valve with electrical flame control;
• piezoelectric element;
• wick;
• thermocouples;
• sensor for monitoring coolant overheating and lack of draft in the smoke exhaust chamber;
• connecting wires.

Emergency shutdown diagram of the gas valve of semi-automatic gas water heaters (dispensers).

When you press the gas valve handle and turn it counterclockwise until it stops, the electric valve opens, the piezoelectric element generates a spark, as a result, the wick is ignited and the thermocouple is heated, which generates an EMF. After 10-30 seconds the voltage should be 15 - 30 mV. This voltage is enough to activate the magnet, which holds the valve stem in the open position. When the electrical protection circuit breaks, the current is lost and the controlled valve moves to the closing position under the action of a spring. Gas stops flowing to the burners and wick.

Reasons for the lack of flame on the wick of a gas water heater

1. The air supply hole in the wick is clogged. This hole allows air to flow in to ensure combustion of natural gas at the igniter tip.
2. The solenoid valve coil has burnt out. An electric magnet holds the valve stem; if it breaks, the valve will close.
3. The thermocouple has failed. The thermocouple, while in the flame, generates voltage that is supplied to the electromagnet.
4. The sensors for monitoring the water temperature and the state of the chimney (presence of draft) are faulty. At values ​​up to + 82 0C, the sensor is in the closed position; above this temperature, its bimetallic plates diverge and the circuit opens. The normal contact between the two plates can be disrupted by surface oxidation, mechanical or thermal damage.
5. The electrical circuit of the flame control system is broken. All elements of the flame control system are interconnected by wires. Their malfunction will inevitably lead to disruption of the entire system.
6. The nozzle or gas supply tube to the wick is clogged. The inner diameter of the tube is 2.5 mm (external 4 mm) and the nozzle outlet diameter is 0.1 mm. These elements can become clogged with soot, dust, etc.
7. The operation of the piezoelectric element is disrupted, the spark from which ignites the gas.

Identifying the reason why the gas water heater does not ignite and eliminating the breakdown

To determine the reason for the lack of flame in the column wick, you must:

• Open the front panel of the device.
• Check the condition of the nozzle and air suction hole, gas supply tube to the igniter. If there is soot or dirt: remove it from the wick.

Ignition system for semi-automatic geysers.

• Examine the piezoelectric element for spark generation. If it is absent, inspect the wires and terminals for mechanical and other damage. Oxide on the contacts must be removed and damage repaired.

The location of the elements of a semi-automatic gas water heater responsible for ignition.

• Determine the thermocouple voltage. To check the heat generator, unscrew the special plug electric valve. Carefully remove the special cable that comes from the thermocouple. Using a multimeter in DC voltage test mode, connect one probe through the Alligator clip to the outer shell, and place the other one against the central contact. Since the height between the contacts is small, make sure that the probes do not touch each other. Use a lighter to heat the working end of the thermocouple. If the voltmeter readings correspond to 15 - 30 mV, the part is serviceable; for other values, the generator must be replaced. If the special wire is not suitable for further use, the entire thermocouple is replaced.
• Examine the valve inductor. In the valve connector, which was released when checking the thermocouple, insert one end of the probe into the middle of the connector, the other onto its body. Tester in ohmmeter mode. The coil resistance should be in the range of 10 - 15 ohms. If the circuit is open or shorted, the ohmmeter will record a value of 1 or 0, respectively. The coil changes modularly, along with the stem and valve.

Measuring the resistance of the solenoid valve coil of a gas water heater.

• Check the serviceability of the monitoring sensors. At room temperature The sensor control contacts are in a closed state. Using a multimeter, in diode test mode, examine the two sensor terminals for circuit continuity. The tester reading if the sensor is working will be 0; in other situations, when the values ​​​​correspond to 1 or a resistance of 1 - 600 Ohms, it must be removed and a working one installed in its place.

Location of the water temperature sensor and the geyser chimney sensor.

• Test the condition of the wires and connections. Wires with sensor contacts are connected by soldering soft solder, with an electromagnet and a thermocouple with a special plug. Carefully inspect the wires, solder joints, and plug connections. Sometimes microcracks form at soldering points, which disrupt the integrity of the entire circuit.

After each remark has been corrected, it is advisable to check whether the column lights up or not.

Geyser Bosch - Troubleshooting

About six months ago I bought myself a Bosch WR 10-2p gas water heater. I installed it myself, and there were no problems during operation; it did not leak anywhere. Now soot has accumulated in it and it has stopped heating the water. I also decided to do the cleaning myself. Share your experience on how to do this. How to properly remove a copper tube? To do this, do you simply lift the bracket and remove the tube? I also want to remove the heat exchanger so that it can be completely cleaned of any contaminants. I also noticed that the flame changed its color. If before it was smooth blue color, then now it is blue and yellow. Why did she get so dirty?

You have poor fresh air flow, so a lot of soot is created. You need to blow off the dust from the burner and rinse the heat exchanger thoroughly. Works for about 2 hours, and instantaneous water heater WR10-2 p23 will be fine.

I have a Bosch WR 13-2p semi-automatic gas water heater installed. It has been working for 5 years, but now a problem has appeared. As soon as the cold weather began, strange things began to happen to her. And the water pressure is very good, gas is also supplied with sufficient pressure. But the water comes in very cold, so in order for it to heat the water as it should, the settings have to be set more high temperature. In this operating mode, after 5-10 minutes of heating, the unit turns off. I don't understand its structure at all, but here's what it seems to me. I suspect that the problem is some kind of sensor responsible for overheating. Perhaps it is very dirty, or broken, and is giving the water heater a false signal. Or maybe my chimney is dirty? How can I repair the device?

Most likely, your chimney draft is broken, and therefore the Bosch column turns off. Overheating protection is triggered; the traction sensor is responsible for it. Judging by the time after which the device turns off, then this is it. But other options are also possible. For example, if your model has a battery, it might be dead. You just need to replace it. It is easy to check the operation of the overheat sensor. You need to close the contacts. If the water heater continues to turn off, it is not due to it. The contacts in the thermocouple-sensor circuit may have oxidized or become loose. Then you will need to check all contacts. There may be a large accumulation of carbon deposits on the thermocouple. Then you will need to clean it. Perhaps the flame does not reach the thermocouple, then it will be necessary to clean the igniter. Gas instantaneous water heaters WR13-2 p23 are available with both a thermocouple and automatic ignition, which feature battery-powered electronics. You have a gas water heater with a thermocouple. It contains a thermocouple connected in series, gas valve and an overheating sensor (draft sensor). If there is poor contact anywhere in this circuit, the gas valve closes. Accordingly, the column goes out. In order to check whether the draft is really good, you need to close the contacts on the overheating sensor. If the device starts working normally, it means the sensor is faulty or there is a problem with the traction. If it continues to work incorrectly, then you need to look at the height of the flame and how much it hits
wick. Very often, a Bosch speaker has a wick set to minimum power, and if the draft is strong, it deflects the flame to the side, naturally it goes out. You need to inspect the water heater to say anything more specific. In any case, you will have to correct this breakdown, since if the traction sensor is faulty, it is prohibited to use the unit.

I decided to buy myself a Bosch W10 kb gas water heater. I studied it from all sides. I have a chimney, it is a pipe with a diameter of 12 cm, 2 m of this pipe lies under the false ceiling, and then hangs 1 m from the ceiling. I want to leave a pipe with a diameter of 12 cm running along the ceiling, and replace the rest with a pipe with a diameter of 6 cm. As I understand, at the junction of the 12 cm and 6 cm pipes, the pressure should drop by 2 times. That is, the flow will slow down. The chimney is even wider, so the pressure there should drop even more. This model has enough installed powerful fan so that there are no problems with neighbors?

You can easily connect a Bosch speaker by taking air from the room. If you look at the instructions, it is written there in detail. Make a transition between 6 cm and 12 cm pipes, then connect your corrugation. All connections must be well insulated, since gas is supplied there under pressure. Your chimney has no impact on your neighbors. Everyone has their own access to the roof. You can also install a splitter to take air from the street and release combustion products into the chimney. Holes smaller than 15 cm do not need to be agreed upon with anyone. The coaxial pipeline should not be taken outside, as it is necessary to maintain the distance to the nearest windows. If you don't live in top floor, you are unlikely to be able to provide this.

Please tell me a Bosch WR 13-2b (gwh 15) gas water heater with electronics. I went to different stores, and the sales assistants constantly confuse everything. I'm afraid that they won't bring the one I want. Tell me also what the dance names 2B and 2P mean? Do any of them have a flow meter installed? If you know how much water has passed through the electronic unit, the dispenser should automatically calculate how much gas
required to heat water? Why then do these models perform so poorly? I don't understand. It should hold the temperature much better than a mechanical one.

The number 2 means the line number. The letter P means that the water heater operates with a constantly burning pilot light.

Gas control is carried out using a thermocouple. The letter B means that the device is battery operated. In it, the igniter burns only when ignition is in progress. Gas control using ionization. The numbers after WH are the number of liters per minute, which at a temperature of 25 degrees, at the set
gas pressure passes through the unit at the inlet. Any dispenser where a mechanical drive of the gas valve from the membrane is implemented, and manual adjustment of the gas supply by a tap is installed, is considered mechanical. In the electronic model, a water block with a membrane is not structurally provided. There is also no manual adjustment of the gas supply using a special switch knob. It establishes the necessary
temperature, and everything else is done automatically. Also installed there are inlet and outlet temperature sensors, and an air flow and turbine speed sensor.

How to turn on the Bosch WR 10 - 2P gas water heater?

It turns out that, no matter what power is set, the device is set to automatic combustion mode to maintain the required temperature. This reduces gas consumption, significantly reduces emissions into the atmosphere, and increases the efficiency of the device. Such water heaters work without problems. But they are usually connected to a 220 volt network. Since all automation and other devices operate from the network. Mechanical models have never been able to maintain the required temperature, since they do not have such systems for this. There was an attempt to release a Bosch Junkers valve-membrane device not only for ignition, but also for burner modulation. But this line was not successful.

I installed a Bosch 10 gas water heater at my place. Moreover, it was adapted to run on liquefied gas. To do this, I installed other injectors and removed jumper j6. But the device won't start, and I don't understand why. When I turn it on, the green button lights up for a few seconds, and then the red light blinks and the fan starts working. No further action occurs.

Since the unit reacts to turning on the water by turning on the fan, first of all you need to make sure that the pressure switch is working properly. This is the weakest point of all smoke exhaust models. If the fan turns on even when the tap is closed, and is blocked, you need to look at the sensors and look for a break. The pressure switch contacts may be incorrectly connected or reversed. After you have readjusted the water heater, it was necessary to check its operation on a regular gas heater to make sure that the unit is working properly and there are no breakdowns. It could have been damaged during delivery. So check the diagram. Check the temperature sensors, check the pressure switch. If possible, go to setup mode and set the regulator to maximum. To do this, the burner buttons must be pressed and held, and then the switch must be switched, which must be held until the flashing starts. Also check the fuses located in the control box.

Water began to flow from my Bosch 15 gas water heater, and it flows out of its upper part. It has been in operation for 8 years, and before that it has never broken down. Can I repair this?

Hardly. Get ready to buy a new water heater.

There was a malfunction of the Bosch WR 10-2 p geyser. It worked for 4 years without any problems, but a month ago its radiator started leaking. In order to find the leak, I took it off and looked. I found damage to the top. It is impossible to solder there because of the ribs. In order to stop the leak, I filled the damaged area with sealant. At the same time I flushed the radiator. The water heater began to work well. But now it has appeared new problem. The device stopped lighting. The pressure is good, but the water coming to the tap is cold. If you look through the viewing window, the gas burns not with a blue, but with a yellow flame. Also, the combustion power is much less. What could have broken? The traction is present, I checked it with a lit newspaper. Gas is supplied with good pressure, checked using gas stove, which burns without problems. The boiler connected to this gas also works.

On a instantaneous gas water heater WR10-2 p23, try disassembling and washing the heat exchanger and burner. You also need to blow out the igniter. This should be done as soon as the flame begins to change color. To solve the problem, try unscrewing the two screws on the side and in the center, but do not remove them entirely. Use a flathead screwdriver to pry up the burner and pull it out. Find the rubber ring there. Don't forget to lubricate it with soap or special silicone grease. Also find the wire with solenoid valve and turn it off, without this you will not be able to disconnect the burner from the unit. The heat exchanger will also have to be removed, as it will interfere with dismantling the burner.

I have a Bosch WR 15 gas water heater installed. We turned off the old electric boiler and took it away, and in its place we installed a device with a generator. Now nothing works. Water is supplied at a pressure of 3 atmospheres. The gas pressure is 2000MP, instead of the required 1300. That is, everything is supplied as it should. This is how we launched it. The first time, ten attempts, after opening the hot water supply tap, clicks were heard from the water heater, and then error EA appeared. The instructions say that there is no gas for the main burner. Tried to run it more than once. After this, the flame appeared. The water began to heat up, but not to desired temperature. The device shows 58 degrees, but in reality the water is much colder. And then the flame went out again. It seems to me that some valve is not working fully. The flame height is no more than 4 cm. To solve the problem, I want to try to adjust the gas pressure in front of the burner. Is it correct?

The pressure is sufficient for the device to work correctly. But please note that it must be measured not only when the water heater is turned off, but also when it is running. It should not fall below 13 millibars. If the gauge shows 58 degrees, then it could theoretically heat up to that temperature.

The initial problems with starting are also logical; there was air in the system and it took time for it to come out. The flame goes out most likely due to the protection being triggered; perhaps you have problems with traction.

Check contacts and sensors. Also check the power supply from the generator using a multimeter. A stuck valve usually either opens or does not open. You can try to blow it gas fittings, but not more than 0.3 kg/cm. It is not designed for higher pressure. You can also check the valve using a 3-volt battery; when it operates, a click is heard.

The Bosch WR 10-2p gas water heater is faulty. When starting, clicks are heard, and sometimes it even lights up, but only if the water supply tap is open to maximum. The water is supplied warm, but not enough. She was much hotter before. After the device starts up, the water supply pressure can already be reduced, and everything will work. If the unit does not want to work at all, I blow cold air on it, and the problem is solved. But you need to clearly find the point at which to blow. It is located next to the green indicator. During this procedure, the indicator flashes, and after a while the device begins to work. Gas is supplied at normal pressure. What could it be?

Try using the right control knob to reduce the flow rate. To do this, you need to turn it towards increasing the temperature to the average value. If you blow air onto a valve or igniter, then you just need to clean the unit from dust. The spark should always appear.

I put into operation a Bosch WR 13-2 geyser. I adjusted the pressure, it's as it should be. But what confuses me is that if the tap is not fully open, at least halfway, the unit “puffs” but does not light up. I found the minimum water pressure in the passport. Is the minimum flow really not standardized?

The passport of the instantaneous water heater WR13-2 p23 indicates both the rated power and the rated flow at a water temperature of 25C. If the water does not heat up to the temperature you want, then the valve is not opening all the way. There can be many reasons for this. We need to figure it out. For example, the water block rod does not move through its full amplitude, and therefore does not fully open the gas shut-off valve. Even a minimal membrane rupture is enough to cause this problem. The internal valves could also be clogged. If you deal with the gas block, then there may be insufficient voltage supplied from the control unit to the valve. It may not be enough for the valve to open all the way. The membrane could also tear or stretch. The rod could have stuck. The control unit supplies voltage, gas from the front cavity is supplied to the pilot burner. The control unit receives a signal that a flame has appeared. After this, it applies voltage to the lower valve, which shuts off the gas supply to the anterior cavity. The gas pressure in the rear cavity moves the membrane forward, and the gas supply valve opens to the main burner. Gas escapes from the front cavity and the igniter turns off. The flame control electrode continues to detect it as the main burner burns. Using the gas supply adjustment knob, you can set the spring stiffness, which counteracts the displacement of the membrane. Adjust the gas valve supplying gas to the main burner accordingly.

Bosch geysers (this is the common name given to instantaneous water heaters) - a device in which cold water, flowing through tubes around a heated heat exchanger, is heated and supplied to the consumer at a given comfortable temperature. Bosch geysers heat water using energy obtained during gas combustion.

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

Today, instantaneous water heaters are produced by companies all over the world; Bosch is rightfully considered the leader in the production of these products. The Bosch concern offers the consumer a wide range of devices with different power characteristics that can satisfy all the homeowner’s needs in heating the required volume of liquid.

Modern Bosch geysers are capable of heating water online. The owner does not need to waste time waiting for the required volume of water to warm up. The instantaneous water heater is stuffed with all kinds of sensors and valves that allow you to receive comfortable temperature at the water point. Bosch geysers, regardless of model, are equipped with power modulation.

Thus, as water consumption increases, the heating intensity automatically increases. If the consumer reduces the pressure by closing the tap, the burner automatically reduces the flame, reducing the intensity of work. The main advantage that unites Bosch geysers is energy efficiency and cost-effectiveness, which result in significant financial savings in the form of gas bills.

Before we begin our review of the Bosch instantaneous water heater, we suggest you decide on the necessary parameters of the device that are suitable for you. There is no need to buy a Bosch geyser with a “reserve” of power; this will only lead to high initial costs and subsequent excess consumption of gas and, as a consequence, financial resources.
