How to turn on a BOSCH gas water heater?

Let's look at how to light a Bosch geyser using the example of Bosch gas instantaneous water heaters WR10.B, WR13.B, WR15.B, produced 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. If there is a long break in operation, air may accumulate in the gas system, 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 hot water tap several times. 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:

Signs of improper operation of the igniter (wick)

Why the wick in a gas water heater goes out - reasons
Let us remind you that the igniter is designed to ignite the main combustion system when water is supplied. The flame occurs as a result of the combustion of a warm air mixture. The igniter heats the thermocouple by physically reaching the main burner.

If the wick goes out, this process fails. In order to prevent overheating of the technical components of the column and, most importantly, gas accumulation, an emergency shutdown of the gas supply is triggered. As a result, the wick goes out automatically.

It is possible to understand that a gas boiler needs extraordinary maintenance without professional knowledge. The consumer can easily verify this by noticing:

predominance of yellow and orange glare of the flame. Normally, the color of the fire is blue with an acceptable inclusion of yellowness of approximately 10%;
excessively noisy operation of the equipment. There will not be absolute silence when the speaker is turned on, but strong crackling or rattling sounds indicate possible problems in some unit.

It must be remembered that in a column equipped with piezo ignition, the pilot light is constantly on. This is necessary for the device to operate instantly when the water is turned on. A non-working wick stops the gas supply to the column.

Setting details

These devices have only one geyser temperature regulator. Thanks to it, the heating temperature and power are adjusted. The self-diagnosis system evaluates the operation of the components when turned on. If there are problems, the red light comes on and the device is blocked from starting. Then it is necessary to adjust the water pressure.

Then you need:

Remove batteries from the compartment;
Turn off the microswitch;
Provide a source of electricity;
Turn on the hot tap and turn on the microswitch;
The pressure on the burner should be maximum;
After saving the settings, the orange lamp will turn on.

In other columns, the water temperature is adjusted by turning the toggle switch and controlling the strength of the water flow.

Unfortunately, it is impossible to easily set the settings according to the instructions. Each system has different meanings. If you have difficulties setting up the gas water heater temperature regulator with your own hands, you should turn to professionals.

Preparatory work before turning on the Bosch instantaneous water heater

Before turning it on for the first time, you need to remove air from the water heater tubes; this can be done by turning on the hot water tap and waiting for a stable flow of water from the tap; this will be indicated by the absence of any extraneous sounds when the hot water tap is open.

Important! This action can protect the metal parts of the water heater from excessive overheating in places where this is not desirable, namely at the joints of the tubes. You may also have to bleed off excess air in the gas pipes; this is done differently on different water heaters.

This usually happens by pressing the gas supply button or unscrewing the screw from the gas adjustment tube; of course, how to do this on a specific heater is written in the instructions for that same water heater. Also, if the water heater is installed after repair, it is necessary to remove air from the pipes, to do this, open the free valve, or do this using the water heater.

Before turning on, make sure there is draft - this may be the reason why the Bosch gas water heater does not ignite, this is stated in most instructions for instantaneous water heaters, to do this, simply bring a lit match to the window on the control panel and by the behavior of the flame you can understand the presence of air draft: case when the flame deviates towards the window on the control panel, it indicates the presence of sufficient air draft, and this means that the operation of the device will be stable.

For full operation of the device, a large amount of air is needed, since the burner of the water heater consumes a large amount of oxygen, and it takes this oxygen from the room where it is installed, to do this, ensure normal air flow, for this, the door to the room with the instantaneous water heater should not be tightly closed, also in An apartment or house must have a constant supply of fresh air from the atmosphere, otherwise there is a high risk of poisoning by the products of the instantaneous water heater burner.

Important! It is not recommended to use a fan or air conditioner while the instantaneous water heater is operating, as this disrupts the normal removal of gas oxidation products through the collector. It is also not recommended to approach the window while the burner is operating, as there is a risk of burns.

Basic rules of use

Do not use the gas water heater before reading the operating instructions supplied with it. Here is a general list of rules that are relevant for any instantaneous water heaters:

Only specialists from the gas supply company can connect the device to the gas main;
changes cannot be made to the design;
ventilation should be maintained in good condition;
for speakers with an open firebox, the chimney must have good draft force;
During operation, the device should not touch the front panel of the water heater and the smoke exhaust elements.

Note! If you smell gas in the room, you must immediately turn off the water heater and ventilate the room. Gas workers should be called to determine the location of the gas leak. Do not operate such a device until the malfunction is resolved.

Do not operate such a device until the malfunction is eliminated.

The following recommendations will help extend the life of your gas water heater:

It is undesirable to set the heating temperature above 55°C to avoid increased scale formation;
it is risky to use a water heater without a water filter if the water in the water supply is hard;
The heat exchanger should be cleaned of scale as it appears.

Compliance with all operating rules will save fuel and increase the service life of the device.

Design and principle of operation of Bosch speakers

Semi-automatic columns - the device contains two burners: main and ignition. The wick burns continuously. When the DHW tap is opened, the igniter ignites the gas on the main burner. The igniter is ignited using a piezoelectric element.
Automatic water heaters - turn on independently when you open the hot water tap. The ignition unit produces a spark to the burner device, igniting the gas. Bosch automatic gas water heaters, in turn, are divided into two subgroups:
battery operated;
using a hydrogen generator to produce sparks.

In addition to being divided according to the principle of ignition, Bosch speakers are divided into two classes according to their internal structure. There are water heaters with a closed (turbo) and open (atmospheric) combustion chamber. Turbocharged ones have built-in fans that force air onto the burner. Atmospheric boilers use natural convection of air masses.

The service life of Bosch speakers is 8-12 years. The service life is affected by the quality of the heated water, compliance with the rules of connection and use established by the manufacturer.

A distinctive feature of Bosch products is a set of simplified functions.

The famous brand produces only high-quality products and has been improving them for many decades. The concern is constantly introducing all sorts of technical innovations into its speakers to make them even more popular.

Popular models

The Electrolux company has proven itself to be the best. This is evidenced by reviews from customers and specialists. Electrolux GWH 265 ERN Nano Plus is a heater in demand today, which is characterized by a power of 20 kW and a capacity of ten liters of water per minute. Thanks to the presence of electric ignition, it is easy to use the appliance; to do this, you just need to change the batteries in a timely manner and open the mixer. The dimensions of the device allow it to be installed even in a small room.

The steel burner of this model and the copper heat exchanger have a long service life. The radiator does not contain oxygen or lead, so the equipment is absolutely safe for others. Nano Plus has a temperature limiter that protects the device from overheating. Judging by consumer reviews, this model is not only compact, but also easy to use. Almost no shortcomings have been noticed, but buyers say that if configured incorrectly, the equipment may malfunction and become noisy. That is why it is necessary to strictly follow the rules in the instructions.

Another interesting equipment model is the Electrolux GWH 350 RN geyser. Its main advantages:

long service life;
simplicity of design;
productivity up to fourteen liters of water per minute;
presence of a window for controlling the flame;
the presence of piezo ignition, so the device does not need to change batteries.

Consumer reviews contain information about some of the disadvantages that arise when using this model:

large body dimensions;
The flame does not ignite instantly.

Users often prefer the Electrolux GWH 275 SRN water heating equipment model. This device is unpretentious, simple and reliable. Advantages:

simple and at the same time interesting design;
simple design that is not burdened by electronics;
long service life;
reliable elements that prevent water leaks;
quick connection and no need to change batteries.

Flaws:

the geyser must be turned off during a long absence, since it has a built-in igniter;
The knobs are too sensitive, so there are some difficulties when setting the temperature.

Design and principle of operation

The Bosch company produces several types of geysers.

Battery powered design. The burner will need to be turned on using electric ignition, and a special electrode will supply the spark.
Bosch device with piezo ignition. You need to light the igniter by simply pressing a button. The heater will begin to heat water only after the owner of the house opens the tap, from which hot water should flow.
Column that can work with a hydrogen generator. This unit works in the same way as with batteries, only the spark is obtained using a hydrogenerator.

Gas devices have a rather complex structure. Before you start searching for the desired model of this type of equipment, it is first better to know the features of its design.

It is worth highlighting several main working components of the products.

Frame. It is produced using stamping from durable sheet steel. The case has an enamel layer of protection, which helps the unit withstand elevated temperatures for a long time, and also provides resistance to various damages. Heating elements and casing parts are fixed behind the housing wall, which covers the “insides” of the column. The boiler control elements are also located on the body.
Viewing window. It looks like a regular hole, which is located on the front side of the product and is made in order to visually control the burner fire.
Control system. This unit has two separate regulators - for pressure and for liquid temperature. Boilers are manufactured with regulation of water pressure, which is produced by turning the knob - you can increase the readings by turning clockwise, and decrease them counterclockwise. The flame level can be set using the slider.

Entrance and exit routes. Both water and fuel will be supplied using fittings with threaded connections.
Chimney. The gas that has already been exhausted goes through the pipe, which is located at the top of the product. The diameter of the pipe will directly depend on the performance of the device and has parameters from 10 to 15 cm.
Traction control unit. This element looks like a sensor. It will monitor the level of available traction. If it drops, the machine will immediately turn off the unit.
Gas unit. This includes a burner and igniter, a special combustion chamber, a special gearbox and all the necessary elements for ignition.
Water node. There is a heat exchanger released from a pipe in the form of a coil, and durable pipes for transferring and exiting liquid.

Products must have means of monitoring the level of fluid pressure in the system. When it drops to critical parameters, the heating element should automatically turn off.

The principle of operation of the gas device follows the following scheme:

as soon as the hot water taps are opened, the necessary coolant enters the heat exchanger;
at the same time, the heating burner is ignited from the igniter;
passing through the coil, the water warms up due to the heat that is released in huge quantities during the combustion of fuel;
rapid heating occurs through heat transfer at high speed due to the high level of thermal conductivity of the materials used;
exhaust gases will escape under the influence of chimney draft.

The Bosch concern offers a choice of water heating products with various subtypes of ignition.

That is why flow-through products are divided into 2 classes.

Ignition the machine. The combustion of fuel in the burner occurs at the same time as the opening of the taps with hot liquid.
Semi-automatic ignition. Ignition of the fuel in the combustion chamber comes from the igniter, which must first be ignited.

The markings of Bosch brand units contain letter indices that indicate the type of ignition system, namely:

“P” – piezo ignition;
“B” – electric ignition;
“H” or “G” – ignition from a hydrogenerator.

Basic rules of use

Peculiarities

Electrolux water heaters are equipment that can heat water and maintain its temperature for a long time without interruption. The design can perform its functions in any conditions. The technical features of the devices provide the speakers with reliability and safety. The water heating equipment of this company is capable of working not only at one or several water intake points. It has found wide use both in the domestic sphere and in offices.

Each model has its own characteristics and performance, so when choosing a product, the buyer should be guided by personal taste and needs. Let's look at the main characteristics of Electrolux speakers.

Power.
The manufacturing company sells a product that can be of three types and differ from each other in performance and power: low-power equipment - 17-19 kilowatts; medium power - 20-24 kilowatts; powerful - 25-31 kilowatts. Each presented option can work at a certain number of water intake points.
Control method.
The manual control method has long been outdated; it has been replaced by a new, more improved one. Modern models of Electrolux geysers have a built-in burner with independent power modeling. Thanks to this, the equipment is able to control the temperature regime and maintain it at the required level, even with insufficient pressure. The automatic system independently selects and regulates the temperature.
Type of ignition.
The manufacturer sells several models of geysers: with manual, automatic and piezo ignition. Equipment of the first option is now practically not found. Automatic ignition is the most convenient option to use.
Safety.
Electrolux speakers are equipped with three-level and four-level security. When unexpected interruptions occur in the system, for example, pressure changes, a gas or water leak occurs, the device turns off automatically.

Electrolux water heating equipment is characterized not only by improved technical parameters, but also by an attractive design. Everyone will be able to choose the ideal option that will fit perfectly into the interior. Gas water heaters are presented both in a minimalist style and with an improved external panel. Devices on the front panel of which you can change pictures to suit the style of the room are very popular.

Common causes of unstable operation of Bosch speakers

If your Bosch gas heater does not light up, you can try to solve the problem yourself. You can find out why the speaker is unstable very easily.

Doesn't light up

The reason may be insufficient water pressure; to do this, clean all filters or check the pressure in the main line, in which case install an additional pump.

The pilot flame goes out

It is necessary to check the safety sensors, if necessary, connect them, or replace them.

Goes off when mixing

The mixer filter may be clogged; if so, clean it. Also, the flow of cold water can simply reduce the pressure of hot water; to do this, you need to set the appropriate temperature of the hot water on the column.

Goes off during operation

It may be a matter of insufficient draft, solve the problem with oxygen access to the burner, and also seal the burner manifold.

Possible other reasons

The main reasons why a Bosch dispenser does not ignite is due to incorrect gas pressure settings. To do this, you need to make the necessary adjustments, and then the burner will burn stably.

Operational nuances

Consider frequently asked questions when using geysers.

Why does the geyser itself turn on or off?

Spontaneous activation of the column can occur if there is a hot water supply system flowing to the column. Accordingly, solving the plumbing problem also solves the column problem.

This situation occurs much more often: the column continues to work even when the tap is turned off. This happens because the aperture (loses elasticity) that is installed in the water regulator is incorrect. Once the user turns off the hot water, he will not be able to take the desired position; he presses the gas sensor for a while. In this case, only replacing the worn part will help.

If the membrane loses elasticity, the column may not close

Is it possible to turn on cold water when the water heater is on?

Many users are lazy, do not know how or do not want to set convenient settings for your column, and adjust the water temperature by adding cold to it. You can't do this, here's why:

This is prohibited in the user manual;
When water is mixed, scale forms on the heat exchanger, which ruins it.

Should I turn off my speaker at night?

In older speaker models and those with piezo ignition, the wick is constantly burning. This, on the one hand, is uneconomical, since gas is constantly consumed, and on the other hand, it is potentially dangerous. It's best to turn off those speakers at night and sleep soundly.

A modern gas water heater does not need to be turned off

Modern geysers have an automatic ignition system. A whole set of equipment is responsible for safety:

Traction sensor;
Flame sensor (monitors its presence);
The temperature sensor allows you to keep it up to 90 degrees.

An alarm from any of them will immediately turn off the speaker. This column cannot be disabled. Usually this point is not even written down in the manual.

Bosch water heaters have electric ignition and an LCD display on the front of the product. The 6000 S series model has 2 fans that remove fuel combustion products necessary to suck in oxygen. The Bosch 8000 S product has a special condensation technology, it is designed for more efficient water heating. In addition, the water valve of this model is supplemented with an electric drive.

Important: all models of gas devices are produced in Portugal, but there is an exception - this is the inexpensive Termo 2000 series, which is assembled in China.

Quality assurance

The gas water heater has certificates of compliance with the requirements of GOST regulatory documents.

Geyser Electrolux GWH 265 ERN NANO PLUS - a geyser with electronic ignition of the burner is easy to use. The burner ignites automatically when the hot water tap is turned on, then the heating power and water temperature are regulated using ergonomic knobs on the front control panel. The presence of flame is monitored by an ionization control unit. The productivity of the NanoPlus geyser is 10 liters per minute.

In this model, the gas burner is made of high quality stainless steel. In the model Geyser Electrolux GWH 265 ERN NANO PLUS, the chimney diameter is 110 mm, which makes it possible to connect to almost any exhaust system.

Heat exchanger

In geysers, the Electrolux GWH 265 ERN NANO PLUS geyser heat exchanger is made of high quality oxygen-free copper using OXYGEN FREE technology, which maximizes its resistance to oxidation and high temperatures during operation and does not require the application of any additional protective layers.

The heat exchanger in NanoPlus geysers does not contain lead and tin, which indicates its safety for human health and the environment, as well as high reliability and durability.

Digital display

On the control panel of the geyser Electrolux GWH 265 ERN NANO PLUS geyser there is a modern digital LCD display with intelligent control. The display shows the water heating temperature, as well as various functions of the column: indication of the presence of a flame on the burner and the presence of water circulation in the heat exchanger, indication of the charge level of the batteries for ignition. If the charge level is insufficient for ignition, the battery icon will flash, indicating that it needs to be replaced.

Multi-level security system

The first level of the security system is a traction sensor. It is triggered when there is no draft in the chimney or reverse draft appears, turning off the gas supply. The second level of the security system - a protective thermostat protects the column from overheating. The third level of safety - a hydraulic safety valve is designed to control the circulation of water in the heat exchanger. This protects the geyser from overheating. The fourth level - flame ionization control controls the presence or absence of a flame on the burner. The intelligent control system controls the operation of all sensors. If any malfunctions or errors occur in the operation of the column, an error code is displayed on the LCD display, which is very convenient when servicing and operating the device.

Operation at low gas pressure

Electrolux geysers are designed taking into account the peculiarities of work in Russia, Ukraine, Kazakhstan, Belarus and other countries of the post-Soviet space, where the pressure of gas and water in the mains is sometimes quite low. The minimum water pressure to turn on is 0.15 bar, gas pressure is 13 mbar.

2 year warranty

How to clean a Bosch speaker

According to Bosch recommendations, the heat exchanger should be flushed every 2 years. The service is performed at the customer's home. In the absence of regular cleaning of the gas water heater, the internal cavity of the heat exchanger becomes so overgrown with scale that washing will only be performed at a service center. Service at the customer's home will be ineffective. At the service center, the coil is washed using a special installation. The chemical reagent is supplied under pressure inside the radiator.

You can clean a Bosch flow-through gas boiler at home, if the internal cavity of the heat exchanger is slightly clogged, using any chemical reagents designed to remove scale. Available remedies can come to the rescue: lemon juice, acetic acid.

Description of the GWH 285 ERN NanoPro column

This Electrolux geyser costs 12,400 rubles. It is a flow-through gas water heater equipped with a stainless steel burner and a copper heat exchanger. The function of maintaining the heating temperature and smooth adjustment are made possible thanks to modern INVERTER Control technology.

The device panel has a heating temperature regulator and a power regulator. There the user will be able to find the key that is responsible for turning it on and off. The operating status indicator is located in a visible place. It will glow green while the burner is operating. Analysis of the operation of the water heater and constant monitoring of operation are provided by Intelligent control technology.

Bosch geyser device

Most consumers, when purchasing water heaters, do not even have an idea about how a Bosch geyser works. The structure inside the unit, made in Germany, consists of a housing, a mounting hole, an inspection window, a water pressure regulator, a fitting for a gas hose, a chimney section of pipe, a draft sensor equipped with a protective manifold, a firebox, piezo ignition and a water unit.

If we consider the operation of a gas water heater, for example, with piezo ignition, then it is incredibly simple and elementary to operate. In order to start using such a column, you must first set the water temperature regulator to the “On” position and only then press the button. It stays at the thermostat until the column turns on. It is also used to select the desired water temperature.

If we consider the specifics of the operation of a gas water heater with automated ignition, then in this case it is even easier to use. If you purchased this particular Bosch gas water heater, how do you light it? This is quite easy to understand. To do this, you need to open the hot water tap, which is located on the mixer. After which the device will turn on on its own.

Therm 4000 S WTD 12 1518 AM E2331.

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, a water tap icon is displayed on the monitor, 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. Setting the minimum temperature reduces energy consumption and makes it possible to reduce the formation of 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.

Gas-consuming equipment is potentially dangerous

To avoid emergency situations, it is important to learn how to use gas water heating equipment. To properly turn on the gas water heater, you must follow certain rules developed by the manufacturer and described in detail in the instruction manual.

Operating manual

If you use the unit correctly and know how to light a Bosch gas water heater, the equipment will seem quite easy to maintain. Before starting work, you must open the water and gas taps. You can light the column in several ways:

Manually. This method is usually used only in older models. To do this, you will need to open the water meter unit and the key valve for the flow of fuel, then light the wick with matches and turn on the gas supply valve. The disadvantage of such units is that you will also need to turn off the valve manually.
Using piezo ignition. Such Bosch gas instantaneous boilers are classified as semi-automatic. First of all, you need to light the main burner by turning on the main regulator in the fuel supply. To ignite the wick, you will need to press a button.
Automatically. These Bosch gas instantaneous boilers are considered improved. Everyone can use them, since their launch is simplified as much as possible. One disadvantage of such columns is that in most houses water is supplied at low pressure, which interferes with the good operation of the turbine.

First of all, any column comes with instructions for adequate operation. First of all, you need to get to know her.

Distinctive features of the units

Bosch has a very large range of speakers compared to its competitors. Each model differs in ignition type, performance, design and dimensions. As for colors, the German company produces units in white and gray shades.

Almost all geysers are designed in Germany, with the exception of inexpensive modifications, which are assembled in China. Currently, there are certain series of Bosch . When choosing, it is first of all advisable to rely on the required performance and financial capabilities.

Suspected breakdowns

If you bought a Bosch gas water heater a long time ago and you know how to light it, but for some reason nothing happens, then in this case you need to look for a solution to the problem in acceptable breakdowns. What could it be?

If the wick in a dispenser running on Bosch gas does not light or it goes out when the tap on the mixer is opened, then in this case you need to examine the gas pressure reducer, provided that it does not stop working on liquefied gas.

When the outlet water is not cool or hot enough, in this case the problem can be eliminated by correctly setting the temperature regulator on the column.

If your Bosch gas water heater does not turn on, you should first check the condition of the batteries and, if necessary, replace them with new ones. Also, many people encounter the fact that after a certain period of time, poor water pressure passes through the column. This can be explained by the fact that the heat exchanger, water unit or water tap is dirty. To get rid of the problem, you need to detect the blockage and remove it.

If you are unable to detect a breakdown and remove it on your own, then in this case you need to contact the warranty service, which will carry out warranty repairs.

Adjusting the water temperature

Open the mixer and evaluate the heating temperature of the water flow. It should be 25 degrees higher than at the entrance. Keep in mind that the gas boiler does not heat the water immediately, you need to wait a little. Use the gas lever to adjust.

Experts do not recommend heating above 55 degrees. This negatively affects the operation of the device, since scale is actively deposited.

The settings take some time, so you don’t need to wait for the results right away. After each stage, you need to drain the water and let it heat up again to check the accuracy of the indicators. Operation may be hampered by reduced pressure in the system.

If the device runs on liquefied gas and there are problems with pressure, do this:

Remove the device casing.
Loosen the locking bolt and measure the readings with a pressure gauge.
Remove the seal from the adjustment screw.
Start the boiler.
Set the maximum values, unscrew all hot water faucets.
Set the required pressure.

Some models are equipped with an additional “Winter-Summer” mode. The heating power of the water in the column depends on the temperature of the inlet flow. In winter, the regulator is set to the “maximum” position - maximum heating. In summer, the inlet temperature is higher, so the value is “minimum”. This saves resources.

Problems with poor water pressure can be corrected by checking. If the equipment has already been in operation and you decide to reconfigure it, but there is no pressure:

Check the rubber membrane. Its operation depends on the pressure in the line. The membrane bends and the gas valve is activated. When it wears out or becomes deformed, the gas supply does not start and the burner does not light up. Replace the membrane.
Mesh filter. Located at the entrance to the water reducer (block). It becomes clogged with small debris from the water supply, so the pressure may decrease. Clean the part.

Tips and tricks for caring for a Bosch geyser

For stable operation of the column, it makes sense to install a filter on cold water, this will prevent wear of the membranes and clogging of the heat exchanger. Also, constantly clean the combustion product collector and heat exchanger.

Important! And the most important thing: use the column in normal operating modes. The Bosch column may not ignite due to various blockages that should be prevented

Many apartments and residential buildings today use gas equipment to heat water. It makes it possible to get running water at a comfortable temperature at any time of the year. However, the prevailing stereotype that “gas water heaters in the house is unsafe” protects a large number of consumers from purchasing HPG. But this is just a prejudice, and modern units have a high level of reliability and safety, and if used correctly, pose absolutely no danger to households.
