How to use the Electrolux column
An Electrolux gas water heater operation license is not required. When drawing up documents for connection, it is enough to provide a passport of the column or indicate the exact name of the model.
How to turn on the Electrolux column
do-it-yourself connection is prohibited
According to the current regulations, the connection can be made by:
- representatives of the company that sold the water heater;
- gas service specialists.
There are several basic rules for connecting:
- installation is carried out in accordance with the rules described in SNiP and SP;
- the first launch is carried out in the presence of an inspector of the Gas Service;
- necessarily withstand the gaps between the stove, refrigerator, sink;
- the installation is carried out in strict accordance with the gas supply project;
- the room used for the boiler room must meet the minimum requirements: height 2.2 m, area of at least 12 m², the presence of a vent or an opening window.
How to set up the Electrolux column
To change the power, the gas supply is increased or decreased, changing the intensity of the flame combustion, focusing on the digital indicators displayed on the screen.
In the device of the Electrolux gas water heater with flame modulation, the adjustments are carried out according to a different principle. The user sets the required water heating temperature. The programmer independently changes the burner power, adapting to the actual pressure in the water supply system.
It is forbidden to adjust the temperature by mixing cold water with hot water.
How to clean an Electrolux column
- the heat exchanger of the Electrolux column - inside the tubes they are overgrown with scale, outside the radiator is covered with carbon deposits;
- burner - nozzles are clogged with soot.
During the repair, the technician will remove the column casing, disconnect the heat exchanger and remove the burner. The coil is washed using special chemicals, under pressure. The radiator fins are cleaned with ordinary soapy water. The burner is cleaned with a metal awl. The work is carried out by a qualified specialist who has an admission and an appropriate license.
What you can do on your own
Before starting work, turn off the gas and water supply to the column. Never try to repair the gas part of the device yourself! This can lead to an emergency.
At home, you can clean:
- soot and carbon burner;
- internal parts from dust;
- heat exchanger - from scale;
- water pipes.
And also check:
- condition of the intake unit;
- tightness of connections;
- serviceability of the thrust sensor;
- presence of lubricant.
All operations are carried out in a specific sequence.
Therm 4000 S WTD 12 1518 AM E2331.
Before starting, you must make sure that, on the plate installed by the manufacturer on the device, the gas marking corresponds to the gas connected to the device. The device has the ability to connect a remote control, which completely duplicates the display on the speaker.
Open the gas cock and water valves. Connect the device to the mains.
The water temperature set by the manufacturer is 42 degrees, this is the optimal temperature.
To turn on the device, you just need to press the turn on button and open the hot water tap. To regulate the temperature, you must press the "+" or "-" button and select the temperature you need. Until your selected temperature is reached, the display will flash on the monitor.
If it does not reach this value within thirty seconds, the water tap icon is displayed on the monitor, which indicates the need to increase or decrease the water consumption. If you press the P button, the programmed constant temperature of 42 degrees will appear. Setting the minimum temperature reduces energy consumption and makes it possible to reduce limescale build-up in the heat exchanger.
But if you know how to turn on the column, but are faced with malfunctions (the flame goes out, does not light up), then where are the causes and methods of their elimination described.
Thanks to its wide range of functions and high quality, the Bosch gas water heater is very popular all over the world. With the help of 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 can 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 principle of operation of water heaters, characteristics and varieties.
Cleaning the heat exchanger of the gas column "Bosch"
If after removing the casing of the water heater and inspecting the heat exchanger, soot contamination is found, it will need to be dismantled and completely flushed. It is necessary to clean the smoked heat exchanger precisely by removing it from the gas column.
The heat exchanger will not look new after cleaning. The challenge here is to eliminate the maximum amount of contamination from the inner plane of the shell and, especially, from the radiator grille.
The first step is to close the shut-off taps for the water and gas supply of the heating column. If you intend to completely remove the device and dismantle the heat exchanger by placing the column on the table (it will be more convenient this way) - disconnect the gas supply hose, the water inlet and outlet, then remove the device from the mounts.
However, there is no need to remove the entire water heater; you can also remove the radiator of the heat exchange module at the place of installation of the device. Let's consider this maintenance option in detail.
Dismantling the water heater heat exchanger
The required tools are flat (minus), Phillips (plus) screwdrivers and pliers.
The pipes for supplying and removing water from the heat exchanger are fixed with brackets, which can be easily removed using a flat screwdriver and thin-lipped platypus pliers
Attention: with an outwardly large size, the heat exchanger is hollow inside and lightweight. When dismantling, handle it carefully, otherwise you will remember the shell!
The procedure for removing the heat exchanger using the example of Bosch WR13-2B:
- Closing the cold water cut-off valve on the supply to the water heater;
- Removing the column cover. Remove the adjusting knobs by pulling towards you, unscrew the two self-tapping screws on the sides at the bottom of the case, push the lower part of the casing towards you, lift and remove from the upper hooks;
- Pulling out the bracket securing the tube to the water distribution unit. Pry off the bracket with a screwdriver, remove with "platypuses", move the tube to the right. Before removing the retaining clip, place a wide container under the drain of about a liter of water from the heat exchanger;
- Removing the terminals of the sensors from the heat exchange tank and the case. Located on the left side of the device, wires go to them;
- Pulling out the bracket that fixes the water supply pipe at the inlet to the heat exchanger (located on the right under it). The principle is the same - pry off with a screwdriver, gently pull out with pliers, then remove the tube completely;
- Removing the protective screen in front of the ignition group by unscrewing two self-tapping screws with a Phillips screwdriver. Then you need to remove the ignition group from the nest, remove it;
- Pulling out the clip from the connecting hose at the outlet from the heat exchange radiator (with a screwdriver and platypus), disconnecting the hose. Do not forget to drain the water first by opening the tap on the sink;
- Unscrewing the two screws securing the main burner on the sides;
- Unscrewing the two screws fixing the gas manifold under the burner (located under it, in the center);
- Removing the guide strip holding the heat exchanger from above. There are two side screws for a Phillips screwdriver. Unscrew and remove the bar.
It remains only to remove the heat exchanger together with the burner. Place the palms of your hands under the burner on its sides and firmly, not without extra effort, press the shell of the heat exchange radiator with your thumbs. Lift them up, then slide the top of the heat exchanger towards you and remove both modules out.
Cleaning the heat exchanger and main burner
For cleaning and rinsing, the heat exchange radiator must be placed in a bath or other suitable container. In order not to scratch the bottom and walls of the bathroom bowl, you should first lay a cloth in it.
Using conventional detergents, hot water and a long-bristled brush, rinse off soot from the inside and outside of the unit. Dry it before re-installing it into the column.
When reassembling, keep in mind that the slight inclination of the side fins should be oriented towards the center of the main burner.
If the burner is soiled with soot, it must be disassembled and cleaned. The fasteners of the burner sections (Venturi tubes) are bolted and can be easily unscrewed.
Professional cleaning of a dusty burner is carried out with compressed air, and at home - with a soft brush and a vacuum cleaner. For severe contamination, wash with soapy water and wipe with a lint-free cloth, then dry and reassemble the burner.
Descaling process
To eliminate deposits of magnesium and calcium salts (scale) in the heat-exchange radiator pipe, you will need to remove it and prepare it for flushing with an acid-containing solution. Note that soot cleaning must be performed before descaling.
It is not profitable to spill prepared cleaning liquid based on citric acid aimlessly. Be sure to use a funnel to fill the heat exchanger tube completely
Do not try to peel off or scale down the inside of the copper tube of the heat exchanger! Firstly, it is practically useless exercise, because the bulk of the mineral deposits in the depth of the pipe will be inaccessible for cleaning. Secondly, scratching the thin walls of the tube will weaken its strength and cause deformation.
The following tools will help to remove scale in the column:
- Anti-scale preparationssold in hardware stores. The procedure for preparing each product for flushing work is indicated in the manufacturer's instructions;
- Lemon acid. Since the volume of the tube in the design of the heat exchanger is about a liter (the exact volume is indicated in the instructions for the device), you will need to prepare a hot solution in the proportion of 100 g of citric acid per 0.5 l of water in a volume of 700-800 ml;
- Nine percent vinegar. Vinegar diluted in three parts of warm water is able to remove scale in the heat exchange radiator of the column. The required volume of the solution is 700-800 ml.
No other means like "Coca-Cola" or homemade solutions based on active acids (hydrochloric, nitric, sulfuric, etc.) can be used for descaling - soda will not work, and acid solutions can damage the tube.
It is necessary to turn the heat exchanger upside down with the radiator plates and upward, insert a funnel into the tube and pour the prepared cleaning solution. Chemical descaling will take several hours, so it is more convenient to fill the heat exchange radiator with a solution from evening to morning.
If the column that has been regularly operated for several years has not been descaled before, then the solution cleaner needs to be changed two or three times until it is completely cleaned. Otherwise, although the scale layer will be reduced, it will not be completely eliminated.
After waiting for the time required for the destruction of scale deposits (more than 4 hours), it is required to pour out the cleaning agent and rinse the tube with a large volume of clean water.During the flushing process, it is important to remove all sludge fragments that have separated from the pipe walls to the outside.
The reasons for overheating the water by the column and how to fix the problem will be introduced to the following article, which is worth reading for all independent home craftsmen.
Features of the
Electrolux water heaters are equipment that for a long time and without interruptions is able to heat water and maintain its temperature. The structure 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 points of water intake. It has found widespread 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 consider the main characteristics of Electrolux speakers.
- Power.
The manufacturing company sells goods, which can be of three types and differ from each other in productivity and power: low-power equipment - 17-19 kilowatts; medium-power - 20-24 kilowatts; powerful - 25-31 kilowatts. Each presented option can work for 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 advanced one. Modern models of Electrolux geysers have a built-in burner with independent power simulation. Thanks to this, the equipment is able to control the temperature regime, as well as 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 gas water heaters: with manual, automatic and piezo ignition. The equipment of the first option is practically not found now. 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 shuts down on its own.
Electrolux water heating technology is characterized not only by improved technical parameters, but also by an attractive design. Everyone will be able to choose for themselves the ideal option that will perfectly fit into the interior. Gas water heaters are presented both in a minimalistic style and with an improved external panel. Devices on the front panel of which you can change pictures that suit the style of the room are very popular.
How to light up the apparatus
Before starting work, you must open the gas and water taps.
There are three ways to light a gas water heater.
Manually
The manual method was used in old-style models
... In this case, you have to light it with matches. Here it was necessary to perform a number of such preliminary manipulations:
- open the water supply connected to the device;
- open the main valve for the fuel flow to the igniter;
- light the wick with matches;
- turn on the valve (main) for gas supply.
With piezo ignition
We can say that this is a semiautomatic column. How to use this type of gas water heater? It will be enough push the button
to ignite the wick in the combustion chamber. With the help of mechanical force, a spark is transformed - it is enough for the ignition filter to ignite. With this method, a number of mandatory requirements must also be met:
- in order to ignite the main burner, it will be necessary to turn on the main regulator in the fuel supply;
- the pilot filter will remain lit when the regulator is returned to the main position and the water is turned off.
Automatically
Fully advanced mods provide automatic activation that is easy and safe to use even for beginners. Hydropower system
offered by most modern manufacturers (Bosch, its direct competitor Electrolux and many others). The process of starting a job is simplified to the limit.
- For example, in the Bosch Therm 6000 O, the water pressure drives the turbine. It starts the automatic ignition system of both the wick and the main burner inside the device.
- The manufacturer Bosch has the Therm 2000 O and Therm 4000 O lines, which carry out electric ignition from batteries (it will be necessary to monitor their service life).
- The Bosch AM1E series speakers already have a digital control panel that will immediately show all possible power-on errors.
A fully automated process has one drawback: in many homes, the water supply pressure is low, and this may not be enough for the normal operation of the turbine. In addition, such devices are significantly more expensive than their less perfect counterparts.
teplomex.ru
In the home appliance market, it is probably already difficult to imagine a brand better known than Bosch. The company has been quite successful in supplying products under its brand all over the world, ranging from irons, refrigerators and ending with power tools. A separate division is the production of heating equipment by the German concern: boilers and water heaters from Bosch-Thermotekhnika.
Bosch solid fuel and gas boilers have been heating homes for many years, both in Russia and abroad. Russian consumers are especially popular with gas water heaters Bosch, reviews of which can often be seen on specialized sites. Buyers are attracted by the quality and reliability at an affordable price for instantaneous water heaters from a German manufacturer.
Let's figure out together whether it is worth buying a Bosch gas water heater today, given such a wide selection of manufacturers in our time. To do this, it is necessary to consider the model range, prices and technical characteristics of the device from the German concern, the disadvantages and advantages in comparison with its direct competitors on the market.
We will make a small overview of Bosch gas water heaters based on the operating instructions, as well as feedback from specialists and buyers. Let's analyze the main malfunctions of the Bosch column: why the igniter does not light up or the wick goes out, etc.
Lineup and features of Bosch gas water heaters
Bosch geysers, unlike their direct competitor - Electrolux speakers, have a very wide range of models. Many modifications with different types of ignition and performance, design and size. Water heaters come in two colors: white and gray.
Gas water heaters Bosch: model range
All gas instantaneous water heaters are assembled in Portugal, the difference is only one, the most budgetary model of the columns - "Therm 2000 O", type W10 KB, which is assembled in China. Now let's take a look at all models and series that are supplied to the Russian market.
1. Series Therm 2000 O
This is a budget gas water heater with a small hot water output of 10 l / min. This device is equipped with an automatic ignition from batteries, a tubular copper heat exchanger and a stainless steel gas burner.
As in the Ariston columns, it contains an emergency draft and flame control sensor, as well as a water temperature sensor and a gas control system. The column "Bosch W10 KB" has a compact size, and you can buy it inexpensively, from 8,000 rubles.
2. Series Therm 4000 O
The most popular models are available both with automatic ignition from batteries and with piezo ignition by pressing a special button. Three types of different capacities and capacities from 10 to 15 l / min are supplied. Bosch geysers of this series have a high-quality copper heat exchanger for heating running water with an extended service life of up to 15 years.
Also, these models are equipped with a smooth modulation of the burner flame, with the help of which the device itself maintains the set outlet water temperature. An important advantage of this model is that this column is turned on at a water pressure of only 0.1 atmosphere.
Instantaneous gas water heaters of this series have the following designation:
- Bosch column with automatic ignition (there is an article "B"): WR 10-2B, WR 13-2B and WR 15-2B;
- Bosch column semiautomatic device with piezoelectric ignition (marked with “P” symbol): WR 10-2P, WR 13-2P, WR 15-2P.
Bosch column with piezo ignition
3. Series Therm 4000 S
The main feature of this model is the presence of a forced draft fan. These columns can work without a chimney, i.e. its special construction is not required. This feature is very convenient when it is not possible to install a chimney in an apartment or house.
The emission of combustion products and the flow of air into the gas column is carried out thanks to a special coaxial chimney, which is installed horizontally through the wall to the street. This kit is an option and is supplied separately from the device itself.
Another important feature of Bosch gas water heaters of the AM1E series is the presence of a digital control panel, on which possible errors are displayed in case of malfunctions of the device. You can also set the water temperature and, thanks to an even smoother and more accurate modulation of the burner flame than the previous model, this water heater will maintain the temperature with an error of only 1 ° C.
The model is produced with three types of power, with a capacity from 12 to 18 l / min. Unlike other models, this series of devices is volatile due to the built-in fan powered by 220 V. They are marked as WTD 12 AM E23, WTD 15 AM E23 and WTD 18 AM E23, depending on their rated power.
Gas water heater Bosch "automatic" with a closed combustion chamber
4. Series Therm 6000 O
The Bosch geyser of the six hundredth series is equipped with a built-in hydrogenerator. Automatic ignition of this model is carried out due to the flow of water through the column. When the tap is opened, water enters the water heater, and the HYDRO POWER technology automatically turns on the gas column through a special hydrodynamic generator.
Neither a piezoelectric element nor power elements (batteries) are required to ignite the device. They are produced in different capacities: 10, 13 and 15 liters per minute. They are abbreviated as WRD 10-2G, WRD 13-2G, WRD 15-2G, the numbers show the performance.
The control panel has a small LCD display that only displays the water temperature. This parameter is set using a mechanical knob on the front of the speaker and is automatically supported by the device.
5. Series Therm 6000 S and 8000 S
These are industrial models of gas water heaters from the German concern. The capacity of these series water heaters is 24 and 27 l / min, respectively. These columns are capable of supplying hot water to 4-5 taps at the same time. Bosch water heaters are equipped with an electric ignition and an informative LCD display on the front side.
The 6000 S series has two built-in fans for flue gas removal and air intake. The Bosch 8000 S water heater, thanks to a special condensation technology, has an increased water heating efficiency. In addition, the water valve of this model is equipped with an electric actuator.
Gas water heater device Bosch
Let's take a closer look at the internal structure of an instantaneous water heater using the example of a Bosch gas water heater of the popular “Therm 4000 O” series, model WR, with piezo ignition.
The internal structure of the Bosch gas water heater
1 - dispenser body 2 - mounting holes for fixing to the wall 3 - viewing window 4 - water pressure regulator 5 - water temperature regulator 6 - gas hose connection 7 - chimney 8 - draft sensor with protective manifold 9 - combustion chamber 10 - gas part 11 - piezo ignition 12 - water unit
The principle of operation of a Bosch gas column with piezo ignition is quite simple. We set the water temperature regulator to the "On" position, press the button of this regulator, simultaneously pressing the piezo ignition button from the bottom. We hold the thermostat button until the column is turned on. We also set the required water temperature.
The principle of ignition of a gas water heater with automatic ignition is even simpler. We open the tap with hot water on the mixer, and the column turns on by itself, thanks to the batteries pre-installed in the device. For Bosch gas water heaters, they come complete with a column. The igniter for devices with piezo ignition burns constantly, and for automatic speakers it dies out when the device is turned off.
Technical characteristics of geysers Bosch WR series
Water heaters from a German manufacturer can operate on both natural and liquefied gas. The diameter of the gas inlet is 3/4 ", the water is 1/2. The diameter of the chimney pipe is different, and depending on the specific model, it ranges from 115 mm to 135 mm. Other parameters can be seen from this table.

Bosch gas water heater malfunctions and repair
1. The igniter flame goes out or the column does not light up the first time.
The ignition burner needs to be cleaned.
2. The igniter goes out or the wick goes out when opening the tap on the mixer.
Check the gas pressure reducer if the column operates on liquefied (bottled) gas.
3. The outlet water is not hot or cool enough.
Check if the temperature regulator on the column is set in the correct position.
4. The igniter goes out periodically.
Perhaps a draft or water temperature sensor is triggered. You need to call a specialist to troubleshoot these problems.
5. Poor water pressure through the column.
There is a clogging of either the column heat exchanger or water unit, or the mixer. Locate the source of the blockage and clean it up.
6. The automatic column does not turn on (does not light up).
Check the condition of the batteries. Replace them with new ones.
Benefits of Bosch speakers
- high-quality assembly; - quality materials; - a wide range of models; - modern technologies; - noiseless operation.
Disadvantages of Bosch gas water heaters
- insufficient number of service centers; - column price; - prices for spare parts.
Today we examined the legendary manufacturer of household appliances, in particular, gas water heaters from the German concern. We analyzed in detail all models, series and technical characteristics gas water heaters Bosch... Reviews can be found different, but the speakers from this manufacturer undoubtedly occupy one of the first places in the ratings for quality and reliability. Watching the video. In fact, the only drawback of the devices of this brand is their price: the model of the Portuguese assembly will cost an average of 12-15 thousand rubles. And it's up to you to decide whether to buy a Bosch gas water heater today or not, of course.
Quality assurance
The gas water heater has certificates of compliance with the requirements of GOST regulatory documents.
Gas water heater Electrolux GWH 265 ERN NANO PLUS - a gas water heater with electronic ignition of the burner is easy to use. The burner is ignited automatically when the hot water tap is turned on, then the heating power and water temperature are adjusted using ergonomic knobs on the front control panel. The flame is monitored by the ionization control unit. The productivity of the NanoPlus gas column 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 gas water heaters Gas water heater Electrolux GWH 265 ERN NANO PLUS the heat exchanger is made of high quality oxygen-free copper using the OHUGEN 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 gas columns 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 gas water heater Electrolux GWH 265 ERN NANO PLUS there is a modern digital LCD display with intelligent control. The display shows the temperature of water heating, as well as various functions of the column operation: indication of the presence of a flame on the burner and the presence of water circulation in the heat exchanger, indication of the battery charge level for ignition. If the charge level is insufficient for ignition, the battery icon will flash, which means that it needs to be replaced.
Multilevel security system
The first level of the security system is the traction sensor. It is triggered in the absence of draft in the chimney or the appearance of a reverse draft, turning off the gas supply. The second level of security system - a safety thermostat protects the column from overheating. The third safety level is a hydraulic safety valve designed to control the circulation of water in the heat exchanger. This protects the gas water heater from overheating. The fourth level - flame ionization control monitors the presence or absence of flame on the burner. The intelligent control system controls the operation of all sensors. In case of any malfunctions or errors in the operation of the column, an error code is displayed on the LCD-display, which is very convenient for maintenance and operation of the device.
Low gas pressure operation
Electrolux geysers are designed taking into account the peculiarities of work in Russia, Ukraine, Kazakhstan, Belarus and in other post-Soviet countries, where the pressure of gas and water in the mains is sometimes quite low. The minimum pressure of water for switching on is 0.15 bar, for gas - 13 mbar.
2 year warranty
Rulers and their features
Unlike the products of the main competitor of the German corporation - "Electrolux", the lineup of the Bosch Group of Companies is distinguished by its variety. Various modifications and form factors are available to customers; the equipment can be ignited according to any of the types of ignition existing today, has different thermal power, productivity (in liters), design and body dimensions.
All models are assembled in Portugal, except for the inexpensive Therm 2000 O, which is traditionally assembled in China. Consider further each series and some of the models included in it separately.
Therm 2000 O
An inexpensive version with a modest performance, producing 10 liters of hot water in 1 minute. Here, ignition is provided with the help of batteries, as well as a tubular copper heat exchanger is built in. The gas burner is made of stainless steel. Like their “colleagues” under the brand name “Ariston”, such GKs are equipped with an emergency sensor for the presence of traction and flame control. The design provides for a temperature water sensor and a "Gas-control" system. GK is made in a compact body, it is relatively cheap - about 8,000 rubles.
Therm 4000 O series
The line contains options with the highest demand. Moreover, there is both with AUTO-ignition from batteries or conventional salt (alkaline) batteries, and with piezo-ignition (you need to press a separate button in order for the flame to light up). The series provides equipment with three levels of power, flowing 10-15 liters per minute. The series is equipped with high quality heat exchangers made of copper and efficiently coping with heating. The serviceability of this unit is limited to 15 years.
These models are supplied with modulating modulation of the burner flame.The function serves to maintain the set outlet flow temperature.
Important! The main plus of Therm 4000 O is that it can be turned on even at a water pressure (head) of only 0.1 atm.
Therm 4000 S
The main distinguishing point is the presence of a fan, which provides forced draft. Columns from this series do not require a chimney to be installed. This is convenient when installing in an apartment or house, where chimney laying will be problematic.
The exhaust of combustion products in these models, like the air flow, is carried out in a coaxial chimney. This element is located on the outside of the wall (horizontally). This is an optional feature, so it must be purchased separately.
Another technical point: the presence of electronic control in the user panel. It displays error codes and other information about the operating modes or malfunctions of the unit. The control panel also makes it easier for the user to do things like set the temperature and others. Precise flame modulation reduces temperature error to just 1 degree.
It is supplied in three different power types, with a capacity ranging from 12 to 18 liters per minute. There is one more significant difference in this series - volatility due to the fan in the design. Unfortunately, this is in some way a minus, because the column will not function without the supply of electricity.
Therm 6000 O
This line of Bosch water heaters is equipped with a hydrogenerator. Auto-ignition is provided by a duct through the structure of the apparatus itself. By opening the tap, the user begins to supply water to the heater, and thanks to the HYDRO POWER technology, an automatic start is carried out by means of a hydrodynamic generator.
No piezo or batteries are needed to ignite the unit. The performance of the models in the series: 10, 13 and 15 liters.
The user panel has a liquid crystal display - it displays information about the temperature, which is adjusted with a rotary knob.
Therm 6000 S and 8000 S
These series include industrial versions with a capacity of 24 and 27 liters per minute. Such units will freely provide hot water supply (DHW) to several points of intake (4-5) without loss of operating power. The units are equipped with electric ignition and display on the side of the user panel.
The 6000 S series model is equipped with two fans at once, which remove combustion products and provide air suction. The 8000 S features a special condensation technology for high heating efficiency of the water stream. Also, the water valve in the 8000 S is equipped with an electric actuator.
How the Bosch gas water heater works
For a detailed acquaintance with the construction of the Bosch Group of Companies, let us consider the structure of the device using an example from the Therm 4000 O series, model WR, equipped with a piezo ignition.
The operation of a device equipped with a piezo ignition is very clear. To start, it is enough to set the thermostat to the "ON" position, press the regulator button, while holding down the ignition button with the help of a piezo. Hold the temperature regulator button until the equipment turns on. Using the same switch, select the desired temperature.
If you choose a water heater equipped with automatic ignition, it will be even easier to cope with the control. To do this, open the DHW tap on the mixer, and that's it - the column will start up by itself. Pre-installed batteries contribute to this. All Bosch water heaters are equipped with branded batteries. They need to be changed about once a year. The device, the igniter of which ignites with the help of a piezo ignition, burns all the time, and in automatic units the flame goes out when the device is turned off.

Most of the faults, as you can see from the table, can be eliminated by yourself. If the boiler does not work after following the described recommendations, you should contact the Gas Service or the service center and call the wizard.
Installing an instantaneous heater makes life much easier for users. You can use hot water without interruption all year round. The main thing is to choose the right technique. The gas water heater "Electrolux" is one of the most popular brands. Why it is special, what are its disadvantages and advantages, read below.
Common malfunctions
Despite the rather high level of reliable operation of these units, it is worth remembering that it is quite common for equipment to fall into disrepair from time to time. But still, German gas water heaters can function for a very long time without any serious failures. In modern operating conditions, such a device will last from 5 to 10 years. A characteristic feature of the speakers from the Bosch brand can be considered a digital control panel, on the screen of which various errors will be shown in case of device breakdowns.
It is worth considering the most common malfunctions, the origins of their occurrence and the quick repair of breakdowns of a gas appliance from Bosch.
- The flame of the wick at the igniter goes out or the product simply does not ignite from the very first time. You just need to thoroughly clean the burner. To do this, it must be removed, carefully disassembled and also carefully cleaned.
- The igniter seems to light up, but it immediately goes out or, for some unknown reason, the wick goes out if you open the mixer tap. It is worth checking the gearbox well if the unit runs on gas from a cylinder.
- The water from the taps is completely not hot or, in general, cold. It is necessary to check if the parameters are set correctly on the temperature controller on the device.
- From time to time, the igniter does not burn. It is likely that this is the reaction of a traction sensor or a sensor for measuring fluid temperature.You just need to call an experienced technician to troubleshoot these problems.
- There is a weak liquid pressure. Most likely, it is either the heat exchanger itself, or the mixer, or the water unit that is clogged. It remains only to identify the source of this clogging and to carry out its complete cleansing.
- The column simply does not turn on (does not light up for any effort). You should carefully check the batteries, if necessary, you should replace them with new ones.
Important: spare parts for Bosch units should only be purchased from specialized dealers.

Description of the column brand GWH 285 ERN NanoPro
This Electrolux gas water heater costs 12,400 rubles. It is an instantaneous gas water heater equipped with a stainless steel burner and a copper heat exchanger. The function of maintaining the heating temperature and smooth adjustment of steel are possible thanks to the modern INVERTER Control technology.
There is a heating temperature regulator and a power regulator on the device panel. There, the user will be able to find a key that is responsible for turning on and off. The operating status indicator is clearly visible. It will glow green while the burner is running. The analysis of the operation of the water heater and constant monitoring of the functioning are provided by the Intelligent control technology.

The difference between these models lies in the amount of heated water per minute. A device equipped with a piezo ignition is indicated by the letter P at the end of the name. It has the ability to regulate two parameters, water and combustion power.To turn on the column, you need to move the slider to the ignition position, drown it.
Press the piezo ignition button several times until a flame appears on the ignition burner. Wait ten seconds, release the slider and move it to the desired power position. Moving the slider to the right increases the power and decreases it to the left. The column is in standby mode all the time, if you need to get hot water, you just need to open the hot water valve.
When you need to turn off, move the slider to the left until it stops. After a couple of seconds, the pilot flame will go out. Close the gas valve and water taps.
In the video below, see the instructions for turning on:
Operating instructions for geysers Bosch
The geyser Bosch wr 10 2p can operate on 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, 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 fluid flow. If you are washing dishes in the kitchen, and someone decided to wash in the shower, the water temperature will be the same, both in the kitchen and in the shower. The power of the liquid at the outlet is also automatically regulated when the pressure of the water in the water supply changes.
Before switching on, according to the operating instructions for the Bosch gas water heater, you must make sure that there is a draft in the chimney. this can be done by holding a lighted candle or a match to the chimney. If the flame deflects towards the chimney, then everything is in order with the draft, and you can turn on the device.
If there is no draft, find out the reason and clean the air duct, or seal the seams of the duct pipes, if a loose fit of its parts is found. When operating the column, make sure that the window or window is slightly open, the door in the room where the column is installed should not close tightly.
Thus, the natural movement of air and the flow of oxygen is ensured, the unit burns a large amount of oxygen during operation. Failure to comply with these requirements can lead to carbon monoxide poisoning. It should also be remembered that when the column is running, you cannot turn on a fan or air conditioner, this interferes with the outflow of carbon monoxide gases through the chimney.
On the front panel of the apparatus on the left there is a slider that regulates the power, on the right is a toggle switch for the volume of liquid, above them there is an observation window. Never get too close to it to avoid burns.

If the start-up occurs for the first time or after a long idle period, some air may accumulate in the column pipes. To remove it, open and close the hot water tap several times, at intervals of about a minute, until it is completely removed.
When using for the first time, open the gas and water supply valves, open the hot water tap to make sure liquid is flowing in.
The Bosch column has a piezo ignition system, the button of which is located at the bottom left. To turn it on, you need to move the slider from the left extreme position to the ignition position, indicated by an asterisk. Drown it and simultaneously press the piezo ignition button several times until the ignition flame appears.
At the same time, loud clicks are heard, you should not be afraid of them, it should be so. If the pilot flame ignites, release the slider button, if ignition does not occur, repeat the entire procedure again. The unit may not start if, after a long period of inactivity or during the first start-up, air has entered the gas pipes. To remove it, hold the slider button in a recessed state until all the air is removed.
Once the unit has turned on, set the power you need using the same slider. The extreme right position provides maximum power, while the gas consumption also increases.With the help of a round knob, the required fluid flow and temperature are set.
By turning the knob clockwise, you decrease the flow and increase the temperature, while turning it counterclockwise, on the contrary, the flow increases, the temperature decreases. Setting a high temperature increases the gas consumption and the formation of limescale in the heat exchanger.
The pilot flame burns constantly, and the main burner ignites when the hot water tap is opened. The shutdown occurs when you turn off the hot water tap. To completely turn off the unit, move the power regulator slider to the extreme left position, the pilot flame will go out ...
If there is a risk of water freezing in the device, for example, in a summer cottage in winter, the water should be completely drained from it. To do this, it is necessary to close the water and gas supply valves, open the valves on the mixer.
Remove the housing cover by unscrewing a few bolts to access the water unit. Remove the bracket in the form of the letter "П" from the filter housing on the water fittings and remove the plug, which is located immediately behind the bracket. Wait a while until the liquid is completely drained.
To prolong the service life of the device, it is necessary to carry out regular maintenance, at least once a year. Clean the inner part of the column from dust and soot, rinse the heat exchanger from scale. In this case, you should be aware that all work with gas equipment should be performed only by a specialist.
After all the work on preparing the Bosch Gaz 6000 boiler for start-up, after pre-start preparation, which includes checking the 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 energizing to the mains on the electronic display, which is located on the front panel of the unit, the "attention" icon appears. Next, press the power button on the front panel, located next to the upper left corner of the electronic display. Above the display is a magnetic instruction allowing easy adjustment of unit settings.
When turned on, within two seconds, the boiler electronics performs self-diagnostics, all sensors are checked and put into blocking mode. The display shows the current temperature and a status code. Next, it is necessary to adapt the fan speed to the length of the chimney to which the unit is connected.
This operation is performed by simultaneously pressing and holding three buttons - "+", "-" and "back". The mode is set in accordance with the parameter specified in the instructions for the device - we set the second service level, confirm the action with the "ok" button, holding it until the square brackets appear on the display.
In addition to the display, in the lower right part, there is a pressure gauge that shows the pressure in the system, the normal pressure is in the green zone. The red zone indicates the pressure below and above the nominal, when the protection is activated and the unit shuts down.
Bosch THERM 4000
You can increase the pressure using the blue valve by unscrewing it counterclockwise until the pressure gauge needle returns to the blue zone. As the pressure rises, fluid is released through the fluted tube at the bottom of the unit and the pressure gauge returns to its normal position.
The boiler can operate in two modes, liquid heating and and heating mode, which of the modes is active is shown by the 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 selection, after which the up and down arrows appear on the display, using the "+" and "-" buttons, set the required heating temperature. To save the selection, press the "ok" button and hold it for a couple of seconds.
If it is necessary to set the heating operation mode, select it with the "-" button, confirm by pressing "ok". The choice of temperature and the saving of the selection is carried out in the same way as when setting the temperature for heating water.The fire icon that appears on the display indicates that the turbine has turned on and heating has begun.
When the set temperature is reached, the fire icon will disappear, after a fall, when the boiler turns on again, it will appear again, this will happen cyclically throughout the entire operation of the boiler with the set parameters. In case of any malfunctions in the operation of Bosch Gaz 6000, for example, in the absence of gas or water supply, the protection will work and an error message will appear on the display.
The explanation of the error and the steps to eliminate it are described in the instructions for the boiler. After identifying and eliminating the cause, it is necessary to confirm the action on the display by pressing and holding the "ok" button for a few seconds. After that, the boiler will automatically start up again.
The unit is protected against freezing if the pump is running and the liquid circulates through the heating system. If the boiler needs to be turned off, then antifreeze is added to the heating liquid, and water is drained from the hot water supply, as a rule, this work is performed by a specialist. Maintenance is also performed by a specialist, since the unit is a rather complex device associated with increased pressure and gas.
We suggest watching a video about the rules for setting up a Bosch 4000 O column:
Device and principle of operation
All gas water heaters have a similar design and system of functioning. The Electrolux geyser on the body has handles - toggle switches, they regulate the heating power and water supply. Each device has its own throughput, some columns can heat up to sixteen liters of liquid per minute. Thanks to the optimal chimney connection, the technology of this manufacturer is characterized by versatility. Geysers can work together with an exhaust system.
Equipment items:
- control pads and adjustment buttons (many Electrolux models are equipped with a display on which you can see the water temperature and all other indicators);
- solenoid valve;
- copper heat exchanger;
- holes for water and gas inlet;
- a hole for the outlet of the heated liquid;
- chimney hole;
- drain cock;
- fasteners.
Due to the quality of parts and design, this equipment is absolutely adapted for use in our country. If the water supply pressure or gas pressure changes in the line, the device will function at the same level. Two tubes are mounted in the body of gas water heaters, the first for the flow of gas, the second for water. At the bottom of the equipment there are burners, which have a basic view and an ignition one. Depending on the selected model, the device has electric ignition, piezo ignition or manual ignition.
How to clean a radiator
You will do the job most efficiently if you completely remove the radiator from the unit. Many will say that flushing the device by removing the heat exchanger is unnecessary manipulation. By doing so, however, you reduce the risk of damage to the machine. To avoid mistakes, proceed consistently:
- Turn off gas and water. Open the closest hot tap.
- Unscrew both union nuts. Depending on the model, you will have to disassemble other elements of the column, cover the burners with a cloth to keep out soot. When finished, carefully remove the assembly.
- Place it in a convenient place, for example, in a bathtub, after covering it with something so as not to damage the enamel.
- Further, cleaning the heat exchanger does not cause any difficulties. The radiator is cleaned of soot by hand using a brush and detergent. In order to remove scale, pour in a special solution and leave for the required time. Then rinse under running water and dry well.
- Reassemble in reverse order, replacing the O-rings at the pipe joints. Before starting the column, check it for leaks.
- Turn on the water. As the mixer tap remains open, the heat exchanger will fill up. Turn off the water and inspect the connections for leaks. If everything is in order, you can resume the gas supply and check the device in operation.
Tip: for nuts that are difficult to unscrew, sprinkle with a softener for solid dirt, for example "VD-40".
Design
- The GWH series water heater has a multi-level security system.
- The first level of the security system is the traction sensor. The sensor is triggered in the absence or appearance of reverse flow, shutting off the gas supply to the main burner.
- The second level of the safety system is a thermocouple, which automatically stops the gas supply when the ignition burner flame goes out.
- The third level of safety is a hydraulic safety valve, which is necessary so that gas flows to the main burner only if water is circulating in the heat exchanger. This protects the gas water heater from overheating.
- The modulating burner automatically adjusts the flame height in response to pressure drops in the water supply system and an increase in water consumption, thereby ensuring the set heating temperature.
- Gas flowing water heaters Electrolux are equipped with a copper heat exchanger.
- The heat exchanger is made of electrolytic copper, the construction of which prevents the formation of scale, and a special coating protects the heat exchanger from high temperatures.
- The burner in Electrolux water heaters is made of high quality stainless steel, which significantly increases its service life.
- The column turns on automatically when you open a hot water tap, thanks to an electric spark from the batteries. After closing the hot water tap, the flame of the pilot burner is automatically turned off. The absence of a pilot burner flame significantly reduces the gas consumption.
- Gas water heater Electrolux of the GWH series can operate in one of two modes - more economical or more powerful.
- The chimney diameter is 110 mm, which makes it possible to connect the water heater to almost any exhaust system.
- True European quality based on modern technologies, perfect design of the water heater and a high level of safety enable reliable and stable operation.
So it's time to write an article not about computers and 1Ski, but about repairing a Bosch / Junkers WR13 gas water heater. Who would have thought that an IT specialist would climb there. Somehow it is established that such things are in the department of gas companies and it is better not to disassemble them without special knowledge. In fact, there is nothing wrong with it, and with more or less straight hands, it is possible to do it yourself. Moreover, there is a crisis in the country and I want to save money. It all started with the fact that the column stopped extinguishing when the hot water was turned off; we had to run around and turn off the gas manually. Googling suggested that two main units are responsible for this: hydraulic fittings (water unit) and gas fittings. They are connected together in such a way that when water is supplied, the water unit, using a membrane pressing on the pin, presses the gas valve, thereby opening the gas supply. When the water is turned off, the gas valve closes. In general, the problem is somewhere here! (figure 14 in the picture)
So, let's get started ... Here he is our patient:
All we need is 2 screwdrivers (Phillips and flat) and a wrench to unscrew the nut that secures the water pipe. For safety, we will shut off the water and gas supply to the apartment. Remove the protective cover by unscrewing the two screws from the bottom:
We get access to the insides: We take out the bracket that fixes the water supply pipe to the heat exchanger:
We take out the branch pipe itself:
We unscrew the two screws securing the water unit to the gas valve:
And then I saw a picture with oxides at the attachment point. The mechanism was carried away, and water seeped out there. The metal oxidized and the gas valve began to jam (it stopped returning to its original position). This is the reason for the non-shutdown of the gas supply! Let's try to clean everything as much as possible and develop the valve itself:
It should press inward and return to its original position. Now let's analyze the water block itself:
We take out the bracket and take out the flow regulator (sleeve with spring):
We unscrew the bolts and remove the cover of the water unit:
Under it we see a worn out membrane:
And the lid itself fell apart from time to time (the column is currently 7 years old):
As it turned out, spare parts for gas water heaters are not so easy to find. And the prices for them are, frankly, horse-drawn. At the price of a new speaker Bosch Junkers GWH 13 P (WR13-2 P2) - 10,000 rubles. I found the cheapest membrane in the city (code 8700503083) for 1400 rubles. and a cover of water fittings WR10, 11, 13, 15 (code 8705500105) for 2400 rubles. Total RUB 3600 More expensive than a third of a column. So before starting the repair, think about whether it is necessary But it was too late ... the column was disassembled and did not want to install a new one, so I decided to continue what I had started! (although I almost freaked out and went for a new Chinese one for the same money) The picture shows old and new parts. The difference is immediately visible:
Now we install a new membrane and a cover of the water fittings, collecting everything in the reverse order:
Hooray. It worked out for me. Now the flame lights up and goes out as it should! What do you want to say in the end ?! When I was puzzled by the choice of a column 7 years ago, I was praised by Junkers as the most reliable and maintainable. I find it difficult to say whether 7 years is a lot or not enough for reliability, although the old Soviet ones still work for people and they have at least something! But with such prices of spare parts, this maintainability is not needed. Now I would choose the cheapest Neva or the Chinese Oasis for 4-5 thousand rubles and in case of a breakdown I would simply throw it out without sweating and put a new one at the price of repairing this Junkers / Bosch. One hope that this prevention will allow the column to work at least as much ... And finally, for those who do not understand in the pictures, I will give a link to a video on disassembling Bosch / Junkers gas burners from Teplotekhnika SPb: https: // www. youtube.com/watch?v=a2aIn93fyQ8
