Today we looked at the legendary manufacturer of household appliances, in particular, geysers from the German concern. All models, series and technical characteristics were analyzed in detail geysers Bosch. Reviews may vary, but speakers from this manufacturer undoubtedly occupy one of the first places in the ratings for quality and reliability. Let's watch the video.

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

Bosch geysers (this is the common name given to instantaneous water heater) - a device in which cold water, flowing through the tubes around the heated heat exchanger, it 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 consumers the widest range devices with different power characteristics that can satisfy all the homeowner’s heating needs required volume liquids.

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.

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 and a heat exchanger tubular type consisting of copper material and steel burner. The units contain a controller for the degree of draft and flame level. The devices were also equipped with a sensor temperature regime liquid and gas flow. This version includes the Bosch W 10 KB device with compact dimensions and estimated cost 8,000 rub.

Bosch 4 000-O THERM

The most popular series of Bosch geysers, which is available with automatic 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 indicators power and productivity level - 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 it is considered possible to operate at a water pressure of plumbing system at 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 in quality 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.

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 reliable system flame modulation. This means that the column automatically adjusts the heating to the required liquid flow. If you are washing dishes in the kitchen, and someone decides to wash in the shower, the water temperature will be the same, both in the kitchen and in the shower. The power of the liquid at the outlet is also automatically adjusted when the water pressure in the water supply system changes.

Before turning it on, according to the operating instructions for the Bosch geyser, you must make sure that there is draft in the chimney. This can be done by holding a lit candle or match to the chimney. If the flame deviates towards the chimney, it means that everything is in order with the draft, and you can turn on the device.

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

This ensures natural movement air and oxygen flow, the unit burns a large amount of oxygen during operation. 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 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 the launch occurs for the first time or after long downtime, 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, and 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. Installation 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. For complete shutdown 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 on preparing the boiler has been completed Bosch Gaz 6000 for launch, after pre-launch preparation, which includes inspection 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 showing the pressure in the system, normal pressure is located 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.

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 required temperature heating 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 produced by a specialist, since the unit is quite complex device associated with high blood pressure and gas.
