What are the features of Bosch gas water heaters, how are they selected


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.

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 ignite), 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.

Gas water heater Bosch / Junkers. DIY repair and modernization.

17 years of life and continuous battle with gas water heaters under the Bosch and Junkers nameplate. The battle is being fought with varying degrees of success, but, I hope, I finally achieved it, and I'll show it in pictures.

Unfortunately, to us in Russia they supply columns of terrible quality, with a factory defect in the most expensive part - a heat exchanger. Replacing the heat exchanger is equal to or slightly less than the cost of a new column, and the warranty is exactly one year.

The speakers for us were made in Spain and now they are made in Portugal.

When I bought the first Bosch WR400 speaker, their leaflets were advertised in full - a service life of up to 50 years and 25 years of flawless operation under conditions of planned maintenance. If I lived in Germany, I would sue the firm.

Now, however, there are no such leaflets, they were ashamed to lie openly.

Here he is the last survivor. Since 2007. Junkers WR15

Gas water heater Bosch / Junkers. DIY repair and modernization. - photo 2
The first battery-fired WR400 speaker lived from 1999 to 2007. The second WR15 column with a piezo ignition normal for people has been living since 2007 - and I won't let it die

Gas water heater Bosch / Junkers. DIY repair and modernization. - photo 3

All to be honest - the date of acquisition is 2007.

Gas water heater Bosch / Junkers. DIY repair and modernization. - photo 4
The first Bosch WR 400 speaker was serviced a couple of times during the warranty year - the wick did not light up. This is a common misfortune of all battery - clicks to itself. But it does not ignite.

And the wick lit and goes out - the heat element is triggered due to a weak fire. The service-man solved this problem by approaching the wick to the heating element, since the construct allowed it.

And in the second year, the heat exchanger tube flowed - this place is the same and marked with number 1... This is the hot water outlet pipe.

The problem is that factory workers bend the tube to a small, unacceptable diameter, which leads to plastic deformation of the tube material itself, and deforms the circular shape of the tube, which leads to turbulence of water inside.

The problem is that this no ordinary unannealed copper pipe with a diameter of 15mm but a thin-walled tube that bends with your fingers. More about this later.

My first water heater started flowing in this very place. My second water heater started flowing exactly in this place. The ejection water heater, where I bought the spare part, leaked at this very place, after a year and a half of work.

Gas water heater Bosch / Junkers. DIY repair and modernization. - photo 5

Well, only then, the same tube flowed on a different fold - marked with number 2.

AND EVERYTHING! Doesn't flow anywhere else! These are two problem areas, and they are a manufacturer's defect.

When the first water heater started flowing in the second year, I was shocked. For immeasurable money bought in 1999 when prices were in euros. Where is 25 years of work here?

VPG-23 with a copper heat exchanger lived with me for 5 years, got it only automatically - it turned off and then it was not turned on. Therefore, he sold it in the hope of a new life. The new happy life was two years old.

Therefore, since this is an obvious factory defect, I wrote in official representative of Bosch / Junkers.And here is the answer of the official representation Bosch / Junkers.

Gas water heater Bosch / Junkers. DIY repair and modernization. - photo 6
Answered me
Valery Oleinikov - that I might be stealing electricity! and therefore Foucault currents flow through the column and electro-chemical erosion of the heat exchanger tube occurs.
Not only did he write to the German office of Bosch that the problem turns out to be the wrong installation. Here is what the German office replied. Bosch / Junkers.

Gas water heater Bosch / Junkers. DIY repair and modernization. - photo 7

“Your problem is not the quality of the product, but the installation conditions. Oleinikov told me about this from Moscow, he can see everything from Moscow. " Therefore, the leak appeared.

Since the cost of the new heat exchanger, if the memory can remember, was 250 euros and it was not sold without installation, we had to fight with varying success.

The place of the leak was visible, it simplified life. Epoxy putty (liquid metal), waterproof, temperatures up to 150 degrees were helpful. Epoxy plasticine is also okay.

Gas water heater Bosch / Junkers. DIY repair and modernization. - photo 8
The problem is that sooner or later, due to thermal expansion / contraction, the epoxy starts to lag behind. And it will flow again.

There are craftsmen who for 2500 rubles. fill the tube with tin. But people write that then it flows again, and that's right - the tube is thin-walled. And tin (soft material) with a braid will not help here. And the pipe is perfectly tied to the casing with tin. Very high quality and forever, so there is no way to replace it.

Normal rubber on the clamp will definitely help - as you can see under arrow 2. Apply epoxy, press with rubber. This is a very, very long time.

Gas water heater Bosch / Junkers. DIY repair and modernization. - photo 9

But then came the moment of truth, when nothing helps. And the solution was radical - to cut the copper pipe and lead the rubber pipe directly.

Gas water heater Bosch / Junkers. DIY repair and modernization. - photo 10
The tube itself is thin-walled, deformed, if you clamp the clamp on it, it is bad. The only normal part, similar to the factory flange, is the exit from the casing, into which the tube itself is soldered. We cut the tube 2-3 cm behind the flange, bend it back to put on the rubber tube.

And then it turns out that the copper tube of the heat exchanger just bends with your fingers.

We put on a rubber tube with a margin and clamp on the flange clamps.

The rubber tube was found by poking at a car dealership. Heater supply hose 2110-8101200-01, to the radiator.For the people's car VAZ.

Made of EPDM material, resistant to high temperature, sunlight, ozone and weathering.

Working temperature: -40 ° С / + 95 ° С for short-term up to 110 ° С

There was a suspicion that the water would stink of rubber, but everything seemed to be fine.

The dimensions fit perfectly, you don't need to cut anything. We put on the exit

fitting 18x1 / 2 HP

The rubber itself is soft, the inner diameter is 16 mm. We bend the outlet pipe with our fingers so that it does not interfere.

Gas water heater Bosch / Junkers. DIY repair and modernization. - photo 12
The temperature behind the casing is low, the hottest place is the entrance, where the steam temperature is over 100 degrees.

Gas water heater Bosch / Junkers. DIY repair and modernization. - photo 13
The tube runs fairly freely.

Gas water heater Bosch / Junkers. DIY repair and modernization. - photo 14
Well, modifications for the little things.

The wick turned off - weak flame to the thermocouple. In this design, all nodes are rigidly fixed, just widen the hole in the tube. Stupidly with an awl.

Gas water heater Bosch / Junkers. DIY repair and modernization. - photo 15

Mechanical filter at the inlet, unscrew it immediately, you still have to have a 5-10 micron main filter on the riser.

Quickly removable connections flow - three or four turns of the fum tape will completely seal the leak.

Gas water heater Bosch / Junkers. DIY repair and modernization. - photo 17
Leaking from the handle of mixing with cold water - remove the handle, it is poorly centered and the axis is tilted.

Gas water heater Bosch / Junkers. DIY repair and modernization. - photo 18

With a leak from under the movable diaphragm stem when turning on the water is more difficult. The good news is that the diaphragm itself will not break here, it is made of very high quality silicone. Flowing - it is necessary to grease the stem well with grease. It is mobile, but the lubricant will not leak. And grease two bolts of the diaphragm fastening.

I also bought this node in reserve, just in case.

That's all.

P.S. And the good news is that the gas part was made with absolutely no quality claims.

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.

Instructions for Gas Instantaneous Water Heaters Bosch GWH Series

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.
  • Security.
    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.

Model range and customer reviews

Therm 2000 series

This model is considered the most budgetary. It can heat a liquid of 10 liters in one minute. It has a built-in electric ignition (powered by batteries), a burner made of stainless steel, a copper heat exchanger, and an original design. The device is protected from accidents by special sensors for measuring the temperature of the coolant and the level of thrust, and there is also a system that monitors the fuel supply.

The Bosch W10 KB model belonging to this series has a small size, low cost, therefore it is in particular demand among buyers.

Termo 4000 series

Bosch products of this modification are presented in two models - Termo 4000 and Termo 4000 S. They can be with electric ignition and piezo ignition. They can produce 10-15 liters in 1 minute. The heat exchanger has a rather long service life - up to 15 years. The models have a system that guarantees smooth flame control and provides the desired liquid temperature with an increase or decrease in the pressure level in the water circuit.

A distinctive feature of the Termo 4000 S model is the installed fan, which forces exhaust gases out of the combustion chamber forcibly and blows air into this chamber.

In addition, you can buy a coaxial type chimney in order to easily remove combustion products from the house. This kind of possibilities help to install these products in those rooms where there is no ventilation system or a chimney is completely absent. There are three types of products with different capacities and efficiency from 10 to 15 liters per minute.

Instantaneous water heaters of this series have such designations as:

  • Bosch device with auto-ignition (article "B"): WR 10-2B and WR 13-2B, as well as WR 15-2B;
  • Bosch semiautomatic unit with piezo ignition (symbol "P"): WR 10-2P and WR 13-2P, in addition - WR 15-2P.

Termo 6000 series

Products in this series are equipped with hydrogenerators to automatically ignite the burner. On the front panel there is an LCD monitor, where the set temperature values ​​are displayed.The heater can be controlled mechanically, and the existing settings are maintained in auto mode. The model is presented in three power options, with performance from 12 liters to 18 liters per minute. However, it is worth remembering that this series of devices is energetically dependent. There is a fan here that needs to be connected to the mains. Products are marked with a marking that depends on the specific power of the device - WTD 12 AM E23, WTD 15 AM E23 and WTD 18 AM E23.

Thermo 6000 S and 8000 S series

These are mostly industrial-type units from a well-known German brand. The efficiency of these products will be 24 and 27 liters per minute. These products can supply 4 to 5 hot water points. Bosch water heaters have an electric ignition and an LCD display on the front of the product. The 6000 S series model has 2 fans that remove the combustion products needed to suck in oxygen. The Bosch 8000 S product has a special condensation technology, it is designed to heat water more efficiently. In addition, the water valve of this model is supplemented with an electric actuator.

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.

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.

  1. 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.
  2. 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).
  3. 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.

How to light a gas water heater: ignition methods

Many consumers are sure that the use of gas water heaters at home is life-threatening, as a gas leak may occur or the column may explode. Previously, old-style speakers were installed in houses, which could fail if the owners ignored precautions when using them. Modern gas water heaters are a new type of device with automatic protection.

If the column is out of order for one reason or another, then the automatic protection makes it so that the gas stops flowing.

You should not use outdated models of gas water heaters - they need an extremely careful and careful approach, which will make its use extremely inconvenient. In order to ignite the old-style column, you must use manual ignition. Modern devices in most cases turn on and work automatically.

Ways to turn on the units:

  1. Manual ignition.
    It is mainly suitable for lighting older models. Earlier to light up the column. It was necessary to use matches to light the wick. First, it was necessary to open the water supply system, which was connected to the column. Then they opened the main valve, and then make sure that gas is supplied to the ignition wick. The ignition wick continued to burn even in the absence of water pressure. It was necessary to turn off the column manually. At home, the use of this type of speaker is undesirable.
  2. Piezo ignition.
    This element is installed in many types of columns. When the button is pressed, the wick ignites in the combustion chamber. The ignition wick ignites due to mechanical force causing a spark. To turn on the main burner, it is necessary to bring the main regulator, which supplies gas, into operation.
  3. Automation.
    Modern modifications involve automatically igniting the wick and the main burner. The turbine is responsible for this, it turns on due to the water pressure. The only problem with the operation of such a column may be insufficient water pressure.

When installing modern speakers, you can be sure that they are safe to use. In order to use them, you do not need special knowledge and skills. But if the column breaks down, you need to contact the gas service directly. It is strictly forbidden to repair the speakers yourself.

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.

What are the features of Bosch gas water heaters, how are they selected

The largest European manufacturer of high-tech equipment BOSCH supplies our market, including gas water heaters. Consider the features of these water heaters, and the main issues of choosing a suitable gas water heater.

The usual design of the BOSCH gas water heater

An instantaneous gas water heater consists of a burner and a heat exchanger installed in the combustion chamber. This main unit is complemented by safety sensors: - combustion, - temperature of flue gases, - water temperature,

whose task is to turn off the column when it goes beyond the set limits, so as not to burn yourself, or turn off the gas supply when the combustion stops.

There is also an electronic control unit, an ignition system (can be of various types), connection fittings ... Everything is compactly placed in an elegant housing that is hung on the wall.

Gas column protection

Models with open and closed combustion chambers

Gas water heaters can be:

  • with an open combustion chamber, working on a high chimney with natural draft;
  • or with a closed chamber, operating under forced draft with a fan, equipped with an air intake through a kaoxial chimney ...

The former can be installed only in a room that is provided with a regulated air supply and equipped with an appropriate chimney. Those. far from everywhere, in most apartments they simply cannot be installed, since it is not allowed to release smoke into the exhaust ventilation.

The second, independent of the air supply and the presence of a special chimney, can be installed almost everywhere in the gas project ...

But in the lines of firms, in accordance with demand, only one or two models with a closed camera are more expensive. The rest - with an atmospheric burner for houses under the chimney. Bosch is no exception, presenting now one turbocharged gas water heater with the marking - WT 13AM1E.

Different ignition system

One of the tricky issues in creating household gas equipment is how to light a flame. Bosch has introduced all types of ignition in its models, since there is still no consensus on "what is really better".

  • The pilot burner in the apparatus carries out the softest, soundless start-up, but who will like the constant gas consumption ...
  • Piezo ignition can be from the mains, batteries, or a water turbine, but there is a pop when starting. A hard start with a delay (gas quality) leads some to think - "now it will explode" ...

For example, the budgetary and very popular BOSCH W 10 KB model of a gas water heater is equipped with a battery-powered ignition, consumers often call it optimal - there is no dependence on either the power supply or the water pressure. But the powerful and "sophisticated" water heater BOSCH WRD 15-2 G is started from a hydraulic turbine ...

The main question of choice is the performance of the Bosch gas water heater

The most significant question when choosing a gas column is its performance.Bosch for domestic use offers a capacity of 10 - 18 liters per minute with powers respectively from 17 to 28 kW.

The performance is indicated in the marking of the models in the form of a number, for example, the current model range of Bosch water heaters - WR 10, WR 13, WR 15, with the addition of various letters to these basic codes indicating additional functions.

For example, in the photo BOSCH WR 10-2P is a popular inexpensive model.

Bosch gas water heater

When choosing speakers Bosch are guided by the following

  • Productivity is 10 l / min - the column is designed for one hot water tap, whether it is a shower or a sink, but they can no longer work together….
  • 13 l / min - there is enough hot water for two taps operating in parallel at a nominal water pressure of 1 - 3 atm.
  • To comfortably fill a bath, or a large bath, or to give water to 3 parallel taps, you need to choose units with a declared capacity of 15 - 18 l / min and a power of 25 kW.

Linear row of bosch speakers

Pressure stability and gas column operation

The work of absolutely any gas water heater may seem of poor quality due to the fact that the outlet water temperature is changing rapidly. But this is a feature of any flow pipes operating in the "heat exchanger-faucet" system, where there is a pulsation of the initial pressure ...

The introduction of a pressure stabilizer-reducer into the circuit helps to partially correct the situation, and also after it - a hydraulic accumulator with preliminary pumping 0.2 atm less than the nominal pressure in the system.

The second technique aimed at maintaining a stable outlet temperature, with a variable pressure, is a modulation burner, i.e. a burner with variable power, which adjusts to the amount of passing water so that only the set water temperature is produced, for example, 40 degrees.

Almost all BOSCH gas flow models are equipped with modulating burners. Only, perhaps, the cheapest and weakest ones can be with manual power settings - you need to pay attention to this when choosing equipment.

gas column connection diagram

At what water pressure do Bosch gas water heaters work?

The Bosch water heaters under consideration are capable of operating at a minimum water pressure of 0.1 atm. The maximum withstand pressure is up to 13 atm. Rated operating 1.0 - 3.0 atm.

If the pressure is higher than the nominal, then a hydraulic reducer should be installed, otherwise the column will not have time to heat the water ...

It is not so difficult to choose a Bosch gas water heater of a European quality level ... It remains only to be sure to stock up on a project and approvals ... It is not allowed to install such equipment on your own.

Gas water heater device Bosch

Many consumers, purchasing water heaters, do not even have an idea of ​​how the Bosch gas water heater is arranged. The internal structure of a German-made unit consists of a body, a mounting hole, a viewing window, a water pressure regulator, a fitting for a gas hose, a chimney, a draft sensor equipped with a protective manifold, a combustion chamber, a piezo ignition and a water unit.

If we consider the work of a gas water heater, for example, with piezo ignition, then it is quite 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 is held at the thermostat until the column turns on. Also, with the help of it, the required water temperature is selected.

If we consider the peculiarity of the operation of a gas water heater with automatic ignition, then in this case it is even easier to use it. If such a Bosch gas water heater was purchased, how to light it? It's very easy to remember. To do this, you need to open the hot water tap, which is located on the mixer. After that, the unit will turn on independently.

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 pipes are mounted in the body of the gas columns, 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.

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.

Mandatory precautions

Any purchased equipment is accompanied by instructions for the correct operation of the gas water heater. The principle of operation of most of them is identical to that indicated above, but here the mandatory adherence to safety precautions should be highlighted.

  1. It is required to conduct preventive cleaning
    gas water heater in order to avoid disruption of the efficiency of its work (how to do this, you can read in the document that goes to the gas water heater - instructions).
  2. It is important to check the condition of the chimney ducts - this will help to avoid clogging.
  3. If the device fails, you should immediately contact gas service
    ... Unauthorized attempts to fix the problem are prohibited.

In more detail, the inclusion of the unit is shown in the video:

It is enough to understand once how to light the device in order to provide comfortable and instant heating of running water. And then you can simply enjoy the operation of this convenient heater.

Let us consider on the example of models of gas flowing water heaters Bosch WR10.B, WR13.B, WR15.B manufactured in Germany, for the markets of Russia, Ukraine, Belarus. These models differ in the amount of heated water.

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

Before starting, check if the gas and water valves are open, if two R batteries with a capacity of 1.5 V are inserted. These heater models are equipped with an electric ignition, as indicated by the B index at the end of the name. Electric ignition takes place with 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 work, it is in standby mode. In order for the heated water to flow, you just need to open the tap. At this point, the pilot flame ignites and after four seconds the main flame is ignited, thus the pilot flame extinguishes after approximately twenty seconds.

These devices do not have a constantly burning wick, which is economical as there is no constant gas flow. During a long break in operation, air can accumulate in the gas system, which will interfere with the correct operation of the igniter and, as a result, will not be able to ignite the main burner.

To eliminate this problem, it is required to open and close the hot water tap several times. Water heating is regulated by reducing its flow, by turning the valve clockwise, it decreases, counterclockwise, respectively, on the contrary, the flow increases and the temperature decreases. At low water temperatures, gas consumption is reduced and less scale is formed in the heat exchanger.
