How to Turn on a Bosch Speaker

Autonomous supply of hot water greatly increases the comfort of living in a modern home. Today, when there is a terrible imbalance in the operation of communal life support systems, for many people the only chance for normal conditions is the installation of geysers.

There are enough offers on the boiler equipment market from both domestic and foreign manufacturers of flow devices operating on gas fuel. When choosing such a device, users pay attention to indicators: durability, efficiency and quality. Bosch geysers (Bosch Group), from a German manufacturer, have been occupying a leading position in the consumer rating of instantaneous water heaters for the past 15 years.

Features of Bosch geysers

The units of this brand are universal and can operate on two types of gas: natural and liquefied. Gas pipes are made for a 3/4 inch connection, and for tap water - 1/2. The pipe for exhausting flue gases into the environment depends on the model, its diameter ranges from 115.0 mm to 135.0 mm.

The Bosch Group of Companies is equipped with emergency sensors for draft in the gas-air path, flame control, a temperature sensor for hot water supply and a “gas control” mode.

Modern units are equipped with automatic ignition using an independent power source from batteries or piezo ignition with a start button.

The Bosch water heater is equipped with a copper boiler for hot water supply, and the plant guarantees its operation for up to 15 years. This is facilitated by a system of smooth modulation of the flame of the burner device, to automatically maintain the specified DHW temperature for the consumer. The achievement of the model is the low threshold of requirements for the parameters of the source water; it starts working already at a pressure of 0.1 atm.

Devices with piezo ignition have a fan to organize draft, so they work with a specially equipped chimney, vented horizontally through the wall into the atmosphere.

Additional Information! The Bosch AM1E series geyser is equipped with an electronic control panel that shows users the temperature conditions of the installation and error codes of the flow unit in real time.

Advantages and disadvantages

These devices have a long history, having been invented in the last century. Consumer interest in the product and the market dictated new requirements for manufacturers to improve units. Much has changed since then, but some things remain the same.

Bosch Group of Companies devices have the following advantages:

Long service life - the Bosch dispenser has been functioning smoothly for decades;
prostate design and maintenance;
wide range of models;
the best security system and indoor gas control;
automatic regulation process and control of hot water temperature;

Disadvantages of Bosch water heaters:

A small number of server centers for maintenance and repair, which does not give users the opportunity to fully participate in the maintenance system;
high prices for a set of Bosch Group of Companies, compared to domestic analogues;
poor spare parts market.

Bosch speaker system

Structurally, Bosch GCs consist of a housing, a hole for installation, a window for monitoring the combustion process, a pressure regulator, a gas fitting, a chimney pipe, a draft sensor, a combustion chamber, piezo ignition and a tap water connection unit.

The body is made by stamping from high-strength sheet steel and is protected from temperatures and aggressive environments by a layer of enamel, which protects the unit not only from chemical and thermal damage, but also from all kinds of impacts. The boiler control knobs are located on the body.

The control system includes two regulators - for pressure and temperature of heated water. The water pressure is regulated mechanically - by turning the knob; clockwise - the flow rate increases, and counterclockwise - it decreases. The torch burning level is set using a slider control. The unit is connected to water and gas supply systems using a threaded connection.

The boiler chimney is made in the form of a pipe with a length of 10 to 15 cm and is used to discharge exhaust flue gases into the atmosphere.

Note! The dispenser operates on the principle of natural circulation, the draft in it is formed due to the height of the chimney and is controlled by a draft sensor, which sends a signal to automatically turn off the dispenser if the parameter drops to “0”.

The gas control system includes a burner, ignition device, combustion chamber, shut-off and control valves and a safety valve. The heating circuit consists of a pipe coil and pipes at the inlet/outlet of tap water. The automation system protects the Bosch gas instantaneous water heater from an emergency and is designed to preserve the equipment and ensure safe living conditions.

Main types of gas flow devices

All Bosch flow dispensers are divided into two classes according to the type of ignition:

Automatic, when the gas is ignited simultaneously with the opening of the hot water taps, the process is carried out using a spark from batteries. The more modern automatic ignition system of Bosch main burners receives a spark from a mini hydraulic turbine operating along the flow of heated water, generating sufficient current to ignite the main burner. This is a more expensive speaker kit, but it is worth it because it ensures complete energy independence of the unit.
Semi-automatic, when first the ignition wick is ignited, which ignites the fuel in the combustion chamber, then the hot water heater turns on automatically when water flows in the hot water system. After stopping water use, the column automatically turns off, and then when the heating cycle is repeated, it will light up again from a constantly burning wick.

Bosch ignition system markings:

“P”—ignition using a piezo igniter;
“B” - electric ignition;
“H” or “G” - ignition using a hydrogenerator.

Therm have three performance types:

wr10-2p - piezo ignition, flow rate 10 l/min;
wr13-2p - semi-automatic, flow rate 13 l/min;
wr15-2p - flow rate 15 l/min.

How to light a gas water heater

After all diagnostic procedures, the column can be started.

Manually

The manual method was used in older models. In this case, you will have to light with matches.

Here you need to perform a number of such manipulations:

Open the water supply connected to the device;
Open the main valve to supply fuel to the igniter;
Light a match with matches;
Turn on the gas (main) valve.

When lighting for the first time, you need to pay attention to where exactly the flame is located, and next time raise the match to a specific place.

With piezo combustion

We can say that this column is a semi-automatic machine. How to use this type of geyser? It will be enough to press the button to light the wick in the combustion chamber. With the help of mechanical force, the spark is transformed. This ignition filter is enough to ignite. When using this method, you must also meet a number of mandatory requirements:

In order to light the main burner, you will need to turn on the main fuel control;
The ignition filter will light up when the regulator returns to its original position and the water turns off.

Automatically

The auto-on feature allows for fully advanced modifications that are easy and safe to use even for beginners. A hydropower system is offered by most modern manufacturers (Bosch, its direct competitor Electrolux and many others). The startup process is simplified to the limit.

For example, in the Bosch Therm 6000 O, water pressure drives a turbine. It triggers an automatic fuse system within the unit for both the wick and the main burner.
Manufacturer Bosch has the Therm 2000 O and Therm 4000 O mowing lines, which provide electric ignition from batteries (you will need to keep an eye on their lifespan).
The Bosch AM1E series speaker systems already have a digital control panel that immediately shows all possible switching errors.

READ Checking Bosch Equipment By Serial Number

The fully automated process has one drawback: many homes have low water pressure, which may not be enough for the turbine to operate properly. In addition, such devices are much more expensive than their less advanced counterparts.

Popular models

Popular models of columns begin to work with a heated water pressure of 0.1 atm, have an automatic system for maintaining the outlet temperature and protection against emergency situations. In addition, Bosch burners have a flame modulation function, which ensures automatic regulation of the burner’s thermal power based on real indicators of the volume of domestic hot water consumption.

This method is ensured by modern construction materials and the level of automation of thermal processes in individual heat supply systems, which makes it possible to ensure temperature conditions with minimal specific energy consumption.

Some of the models of water heating equipment

Bosch model WR10

Various types of gas water heater manufactured by Bosch are represented by a fairly large number of designs. The manufacturer suggests choosing the option with the most suitable characteristics and even shade. This could be the W 10 KB model, equipped with a safety system to improve the quality of combustion products emission. A reliable Bosch gas water heater maintains a certain outlet temperature. The heat exchanger is made of copper. The thermal power of the device is 17.5 kW. The device in this version costs an average of 6,500 rubles.

A slightly more functional option is the Bosch geyser model WR10 2 P23. Its power is 17.4 kW, the design provides for piezo ignition, and the device is turned on by pressing two buttons. These manipulations lead to ignition of the wick, which, in turn, ignites the burner. Such a device is capable of independently adjusting the flame level, which is affected by water pressure. As a result, the Bosch WR10 2 P23 geyser maintains a certain temperature regime even under conditions of pressure changes in the communication system, which affects the intensity of water supply.

Watch a video review of the WT 13 model:

There are also more expensive devices produced by this manufacturer, in particular, this version is WT 13 AM 1E. The design provides a closed combustion chamber, for the full functioning of which there is a supply pipe for sucking air from the outside.

The same air duct serves as a discharge element, as it removes combustion products outside the room, that is, to the street. One of the advantages of this model is the ability to operate even at a pressure level of 0.3 bar. This will allow you not to be dependent on the pressure in the system. The price of such a device is 30,000 rubles.

All the pros and cons

Considering the long period during which the company has been offering its services on the market, you can be confident in the reliability and build quality of such equipment. Other advantages can be mentioned:

A wide range of options, thanks to which the user can choose the most suitable one for use in specific conditions, that is, “for himself”;
Security system, thanks to which quality control of combustion products removal is carried out;
Bosch gas water heater of various types is not affected by changes in operating conditions, in particular, pressure fluctuations in the communication system;
Maintains temperature conditions regardless of pressure;
Most models of such equipment are turned on without human intervention - through automation.

Customers' opinions

In the vast majority of cases, the high level of reliability of devices of this brand is confirmed. However, in some situations, troubles also happen. For example, a Bosch brand geyser model WR 10-2P has a short-lived heat exchanger (it can leak over time), and there are also problems with the operation of the wick.

Otherwise, the devices of this brand are reliable and capable of functioning for quite a long time. Considering that in modern conditions the average service life of household appliances is 1-3 years, depending on the design of the device, it is nice to receive a device that will last up to 4 or even 5 years in a row.

There is one more nuance that does not affect the quality of the equipment, however, it can bring some inconvenience to life. We are talking about increased noise levels. A Bosch brand gas water heater of various types operates a little louder than a refrigerator, which, again, is discovered during operation. For some users this is not a determining criterion, for others it is a very noticeable drawback. Therefore, the decision about whether a particular model is suitable or not should be made after evaluating all the properties, as well as studying reviews.

Main selection criteria: equipment power, type of ignition, temperature control. The most simple (but very functional) models are offered at similar prices as analogues from other brands. There is equipment offered at a higher price, which will differ in the number of additional features.

User manual

In accordance with the Bosch operating instructions, before starting the unit, make sure that there is draft in the smoke path. To do this, bring a lit match to the chimney, the flame of which should deviate in its direction. If there is no traction, then the cause is established. Based on the results of the operation of such units, most often the reasons for low vacuum in the boiler furnace are the inclusion of soot in the chimneys or depressurization of the air duct seams due to a loose fit of its parts. All this must be eliminated immediately, independently and always before starting the unit.

Note! Before ignition, the speakers provide ventilation in the device room; for this, the window and doors of the room are always kept open. During its operation, it is forbidden to turn on powerful fans or air conditioning, so as not to interfere with the natural outflow of carbon monoxide through the chimney.

When starting the dispenser after a long period of inactivity or for the first time, you need to take into account that air may accumulate in the pipe system, which will need to be removed. To do this, open/close the hot water tap at regular intervals of approximately 1 minute until the air pockets are completely removed. After this, move the slider on the working panel from the extreme left position to the “ignition” mode with an asterisk sign. Press it and simultaneously press the piezo ignition button several times until the torch appears.

During this step, you will hear some loud clicking noises coming from the device - this is normal.

After the igniter is ignited, release the slider button, at this moment the main burner should start, if it does not ignite, after ventilating the firebox for several minutes, ignition is repeated according to the above procedure.

After stable combustion has been established in the column, the heating power is adjusted using the slider - the extreme right position gives maximum heating output and gas consumption. The round knob sets the required water flow and its temperature, clockwise, the water flow decreases and the temperature increases, and in the other direction the opposite is true. This process is carried out carefully, because an excessive increase in the temperature of the heated water increases not only the gas consumption for heating, but also the processes of scale formation in the copper heater.

Note! During boiler operation, the pilot light is constantly on, and the main burner device is ignited only when the hot water tap is opened. In order to completely turn off the column, move the power slider to the extreme left position, at this moment the igniter turns off and the torch goes out.

Preparing for work

If you want to start a geyser for the first time or after a long period of inactivity, you need to follow some rules.

Ventilation

It is necessary to ensure a constant flow of fresh air. This is necessary for normal combustion and removal of carbon monoxide residues from the room. There is usually a gap of a few centimeters under the kitchen door specifically for ventilation. For safety reasons, bridging this gap is not recommended. This is especially true for those houses where modern sealed windows without a supply valve are installed.

If the column is located in the bathroom, the door cannot be completely closed. For air circulation, it must remain open at least 3-5 cm. You can use a child door lock.

Traction test

Check the quality of draft in the chimney. This is necessary to remove combustion products (gases) from the kitchen. This is easy to do: you need to hold a thin strip of paper or napkin to the chimney outlet window. If the draft is good, the sheet of paper will be inclined towards the hood.

The flame is deflected towards the chimney. This means the traction is good

Lack of traction is a problem that needs to be solved. We need to check the passage is blocked. To do this you need to look into the inspection hatch. It is located in the chimney of the column up to the point of its connection with the building. Many, unfortunately, close the hatch for decorative purposes. There is no other way to check and clean the chimney, so the hatch must be open.

Most often, the problem is solved immediately: all the dirt, dust clouds, and fragments of bricks falling from the pipe accumulate in this place. Then, using a mirror or phone with a camera and a flashlight, you need to check for congestion in the upward direction.

Sometimes the following situation arises: the passage is clear, but there is no traction. There may be an airlock. A certain amount of cold air accumulated at the bottom and clogged the pipe. You need to warm the air. To do this, you can burn something right in the hatch or isolate the place using AL-KO (tourist match).

Gas leak test

After turning off the column, unscrew (open) the valve on the gas pipe. There should be no smell of gas coming from the device or any connection. To be safe, you can use soapy water on taps and at intersections. If there is a leak, the foam will bubble quickly. If a problem is found, contact your gas supply company to have it fixed.

If there are soap bubbles, gas will flow

User reviews about Bosch units

Gas water heaters of this brand are very reliable and popular equipment; user reviews are mostly positive and are aimed at ensuring that new owners of Bosch equipment can take into account their experience. Of course, there are also negative reviews on the Internet, but if you analyze them, then basically the unsuccessful experience of purchasing a speaker is caused by incorrect selection of equipment or non-compliance with warranty obligations.

Here are some user opinions on Bosch gas instantaneous water heaters:

Oleg, Tyumen region: “We purchased and installed a Bosch Therm 4000WR 13-2P column model. A big plus for us was its fuel versatility: natural/liquefied gas. Disadvantages include increased sensitivity to the quality of tap water. We consulted with specialists and installed cleaning filters right at the entrance to the house. The problem has gone away, at least the last two maintenance services did not reveal any scale.”

Grigory, Aleksandro-Nevsky district, Ryazan region: “For 3 years of operation of the Bosch Therm 2000 OW 10 KB there were no problems, scale does not bother me. When the boiler was removed for washing, the level of deposits was less than 1 mm, but for prevention, I washed the surfaces with anti-scale agent using a shower hose.”

Maria, Nevelsky district, Pskov region: “We bought a BOSCH WR10-2P model instead of a rotten Bosch gas water heater, which had worked for about 20 years. The husband was amazed that all the fastenings matched. I like the model, it has a fairly progressive control panel, it works automatically, the crackling sound of the boiler after it’s turned off is a little annoying.”

Note! The Germans are meticulous people and require strict implementation of all points of the instructions, so those who decide to purchase any Bosch unit should start with the correct choice of equipment and study the factory operating instructions.

A week ago my mother had a gas water heater installed, but she doesn’t use it. She doesn’t know how to turn it on, but she put the instructions somewhere and can’t find them. I’m going to see her in the evening, so I need help, tell me how to properly turn on the Bosch WR 10 - 2P gas water heater?

The instructions for the Bosch WR 10 - 2P boiler indicate that the first start-up should be carried out by those who installed the boiler, but if you decide to do it yourself, then follow this order:

Open the water and gas taps.
There is a power adjustment slider on the front panel, press and hold it.

Press the piezoelectric gas ignition button.

Release the button on the power control and move the slider left or right to set the desired power.
Adjust the water supply using the appropriate regulator.

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 hot water valve.

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. Turn off the gas valve 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 work, make sure that the label on the device installed by the manufacturer on the device matches the gas connected to the device. You can connect the remote control to a device that completely duplicates the display on the column.

Open the gas valve and water valves. Connect the machine to a power source.

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

To turn on the device, simply press the power button and open the hot water tap. To adjust the temperature, press the "" or "-" button and select the desired temperature. Until the temperature you selected is displayed.

If it does not reach this value within thirty seconds, the tap water icon will be displayed on the monitor, indicating that the water flow needs to be increased or decreased. If you press the P button, the programmed constant temperature of 42 degrees will appear. Setting the minimum temperature reduces energy consumption and reduces scale formation in the heat exchanger.

But if you know how to turn on the column, but you have a problem (the flame goes out, it does not light up), then read this article, which describes the reasons and how to solve them.
