Manufacturer information Vaillant
Vaillant is the most famous heating brand in Europe, which recently celebrated its 145th anniversary. The company's products are well known all over the world. Today the concern has 14 enterprises in eight countries, employing 12,000 people. Vaillant's area of interest is not only heating systems, but also alternative energy.
The Vaillant brand officially began its activities in 1874 with a workshop for the production of pumps. Then the Johann Vaillant was created, an enclosed gas water heater that brought about a technical revolution in the industry. In 1905 Vaillant became a manufacturer of domestic wall-mounted water heaters.
All these years, the company not only reconstructed its developments, introducing the latest production technologies, but also searched for alternative technologies for the utility needs of households. In 2010 Vaillant develops advanced models with zeolite gas heat pump. Households can now harness the natural heating properties of zeolite and water. This revolutionary technology is new to thermal power equipment as the heat pump uses recycled energy and reduces CO2 emissions.
In 2011, production of the first home power station, ecoPOWER 1.0, began producing heat and electricity. The smart, preset, all-in-one system is environmentally friendly and extremely efficient.
In August 2012, the company began producing a hybrid model of a 3 kW heat pump paired with a boiler, thus ensuring maximum energy efficiency during operation.
Additional Information! In 2015, Vaillant introduced a range of environmentally friendly and efficient products that meet the highest standards: ecoTEC exclusive, flexoTHERM exclusive and flexoCOMPACT exclusive - the company's first products to bear the Green iQ label.
Vaillant Company
Vaillant is known as a leading manufacturer of floor-mounted and wall-mounted heating boilers operating on different types of fuel (liquefied and natural gas, liquid fuel), as well as instantaneous and storage water heaters. In addition, among the products manufactured by the company's enterprises there are various types of electrical appliances and control devices.
The company was registered in 1874 by entrepreneur and talented engineer Johan Vaillant. Initially, the artisanal workshop he created was engaged in the installation of plumbing fixtures in the city of Remscheid, where the head office of the now world-famous company is still located. After J. Vaillant developed and patented a device in which water flowing through a tube was heated by the flame of a gas burner, the scope of the company’s activities changed dramatically.
The world's first floor-standing gas water heater, Gas-Badeofen, which later served as a prototype for modern closed-circuit gas boilers, was manufactured in 1894. He was followed by:
- the first wall-mounted instantaneous gas water heater Geyzer (1905);
- a floor-standing gas heating boiler (1924), which laid the foundation for the creation of a system for simultaneous heating of several rooms through a central distributor, which became the prototype of modern central heating;
- a system for removing combustion products through the wall (1959), which made it possible to install gas boilers in apartments;
Over the past 125 years, the once artisanal workshop has turned into the largest European concern, the Vaillant Group, with branches located in many countries around the world.
Installation of Vaillant geysers
The most important parameter of any heater is the thermal load. For Vaillant it is in the range from 10.0 to 30.0 kW. The water heating rate in l/min depends on this size. When selecting a model, they study the dimensions, weight and another very important characteristic - the cross-sectional size of the chimney. Modern Valiant gas water heaters are equipped with semi-automatic ignition using piezo ignition and automatic with electronic start control.
Piezo ignition is performed by the user through the start button, when pressed, a spark appears that ignites the wick, after which the gas in the burner device ignites. When the device is operating, the wick burns constantly, which leads to excessive gas consumption. Therefore, a more efficient and advanced starting system is with electronic ignition, when the spark appears automatically.
According to the mode selected by the user when starting the boiler, the source of the spark is ordinary batteries or the electrical network. In GRX type devices with a water flow rate of more than 2.2 l/min, the power supply for electronic ignition is generated by a built-in generator that operates due to the movement of incoming water.
Flow devices of types RXI and GRX are equipped with a draft tipping sensor, which monitors the vacuum in the column and if it is “0”, it automatically shuts off the gas supply so that flue gases do not enter the room. The Vaillant type RXI column is equipped with overheating protection in the heat exchanger, which shuts off the gas supply if the permissible values are exceeded. The burner device for burning gas is made of chromium-nickel steel. The column control unit is performed by 2 knobs located on the front panel.
Important! The GRX and RXI devices are equipped with a gas pressure regulator, which allows the device to operate stably at gas parameters from 13 to 20 mbar, as well as a copper heat exchanger with SUPRAL anti-corrosion coating.

Operating manual MAG pro 835292_02
general information
MAG pro devices are ready for connection. They just need to be connected to the pipelines and gas exhaust system. They serve to supply hot water to one or more water points, such as washbasins, showers and bathtubs. The devices must be connected to a natural draft gas exhaust system (chimney). They are equipped with a maintenance-free piezoelectric igniter for the pilot burner. All gas instantaneous water heaters are equipped with a draft tipping sensor (sometimes also called a sensor for the release of combustion products into the room), which, in the event of a malfunction in the gas outlet pipeline, interrupts the gas supply to the burner. The devices can be adapted to the type of gas available. To convert the device to another type of gas, contact a specialist certified by Vaillant from a specialized licensed enterprise.
After installation, the installer noted the exact designation of your device in the installation manual in the table. 10.2 “Setting parameters depending on the type of gas.”

Principle of operation
The Vaillant gas instantaneous water heater is easy to use. For units
with an open combustion chamber, draft is created naturally and depends on the height of the chimney.
Operating principle:
- After opening the hot water tap, it passes through the gas valve reducer with a built-in membrane.
- Due to the increase in pressure in the water supply, the rubber membrane bends and acts on the plate, pushing out the water rod, which presses with a pressure of about 50 kg on the gas valve, opening it, after which gas begins to flow into the combustion area.
- At the same time, the rod presses on the plate, as a result, the batteries are turned on, producing a spark for ignition.
- After the flame ignites, the flame sensor sends a signal to the module that turns off the spark plug.
- After closing the hot water tap, the pressure in the water supply network decreases, the gas valve cuts off the gas supply to the devices, and the heating process stops.
- The ionization sensor, when detecting the absence of a torch within 6-7 seconds, sends a signal to the control board, which turns off the gas supply. This protection system prevents carbon monoxide from accumulating and entering the room.
- The temperature sensor is responsible for the degree of water heating; if the heated water limits are exceeded, the electronic control board also shuts off the gas.
Note! The draft sensor is responsible for the normal circulation of flue gases, their release into the atmosphere, and the prevention of gas contamination in the room. When it drops to “0,” for example, when the flue is clogged with soot, the sensor sends a signal to the control unit, which turns off the gas supply.
Popular models
The Vailant AtmoMAG exclusiv RXI geyser is equipped with a modulating burner and automatic ignition from batteries. The possible variation in the heat output of the burner device is in the range from 30.0 -100.0%. The process takes place automatically and the combustion rate is programmed by changing the pressure of the heated medium.
Another popular model is a semi-automatic column with piezo ignition, draft sensor and overheating protection AtmoMAG exclusiv RXZ - the device has a built-in modulation burner and an electronic torch control sensor. The modification is universal, runs on two types of fuel, ensuring stable operation at low gas parameters.
Area of use and technical characteristics
Vailant gas boilers are designed for heating domestic and industrial premises. Depending on the model they have different power ranges. From small devices, for example, Eco Compact at 4 kW, to devices with higher power, for example, Eco Craft VKK at 294 kW. Also, if necessary, a number of models can be connected in a cascade to accumulate the generated thermal energy.
Both wall-mounted and floor-standing units are available. Depending on the type of combustion chamber, atmospheric and turbocharged series are produced. For example, Vailant T3 and T4, where T3 is equipped with an atmospheric combustion chamber, and T4 is equipped with a closed combustion chamber. The heat exchanger is made of copper, stainless steel or cast iron.
All devices are equipped with modern protection devices: against freezing, overheating, fire extinguishing and lack of draft. Some devices can operate on both natural and liquefied gas. All boilers have an electronic control system and automatic ignition. Modulating burners allow you to smoothly change the required work intensity.

Instructions for turning on and servicing Vaillant speakers:
- Before turning on the Vaillant geyser, open the gas and water taps.
- Light the igniter; to do this, press the load regulator and turn it from the “Off” position to “Ignition”, while simultaneously pressing the piezoelectric ignition button.
- Check the presence of the torch through the viewing window.
- Release the piezo ignition button and hold the power regulator pressed for
about 10 more seconds. - If the device is not ignited, hold the regulator knob for up to 60 seconds to ventilate the gas duct, and repeat the start with piezo ignition.
- After creating a steadily burning torch, turn the power regulator from “Ignition” to the “On” position. In this mode, when the hot water tap is opened, the column will automatically start working, and when closed, it will turn off.
- The water temperature is set by a thermostat on the device panel. To increase it, rotate the knob to the right, and to decrease it, rotate it to the left.
- To turn off the speakers, turn the power control from the “On” position to the “Off” position while holding it down.
- Close the shut-off valves on the gas and water lines.
Device
The speaker has a steel enameled body. Some models have a window on its front through which you can see how the burner works. At the bottom of the panel there are:
- burner power adjustment knob;
- equipment operation indicators;
- water temperature switch.
Installed inside the case:
- heat exchanger;
- system operation sensors;
- gas fittings;
- burners;
- traction fuse;
- power and temperature regulators;
- wick.
During operation, the unit body does not heat up. The “internals” are reliably protected by the front panel, which can be quickly removed if necessary.
How to turn on a Vailant geyser depends on the model. The manufacturer uses piezo ignition or automatic start of the device.
In the first case, a button connected to a piezoelectric element is placed on the front panel. When it is pressed, a special electrode produces a spark to the wick and ignites it. The main burner starts working from it. If hot water is needed, the user opens the tap and presses the ignition button.
With an automatic burner start system, you just need to turn on the water. The column has a power source that will light the burner. This could be a battery, an electrical outlet, or a generator.
The heat exchanger for the Vailant geyser is made of copper. This metal is more durable and less susceptible to heat. The device can easily withstand temperature changes and high pressure.
All processes are automated. Sensors help correct the operation of the Vaillant column. The gas pressure regulator protects the unit from overheating by turning it off when the tap is closed. Traction sensors monitor the correct operation of the device. In emergency situations, they give a signal that turns off the equipment. A water pressure sensor helps regulate the operation of the burner and prevents the column from starting when the pressure in the system is low.
Vaillant geysers are safe - they will turn off in the absence of gas and water, if there is no draft or the flame accidentally goes out.
Possible faults and solutions
The Vailant gas water heater operates in aggressive and high-temperature environments, so sooner or later it fails, and the same can be said about other similar models. The reduced service life of such devices is affected by the quality of raw water and violation of factory operating rules.
Main malfunctions of Vaillant models:
- The wick does not light up - the thermocouple or gas valve is not working, they will need to be replaced.
- The unit overheats and makes noise - the heat exchanger is clogged with scale. In this model it is not repaired, but replaced with a new one.
- Water under the column is a leak from the heat exchanger.
- The igniter spark does not turn on - the torch controller will need to be replaced or the ignition spark repaired.
- The device smokes, gases penetrate into the room - the gas duct or heat exchanger on the gas side is clogged, it is recommended to clean it from soot.
- Malfunction of the water unit due to stretching or contamination of the rubber membrane pushing out the gas valve rod. It is recommended to replace it with silicone, which is more resistant to constant stretching.
Condensing equipment
Condensing boilers from the Vailant company are especially popular due to their efficiency, high efficiency and excellent heating efficiency.
ecoTEC plus series VUW 246-346
This wall-mounted double-circuit condensing unit has a built-in calorMATIC 370 programmer, which allows you to set different heating modes for a week in advance.

User reviews
Gas water heaters of German quality leave a good impression on buyers; they create practically no problems for them if they were initially correctly selected and installed by the service department.
User reviews help buyers make a more accurate choice based on real conditions and take into account useful operating experience, here are some of them.
Nikolay, 34 years old (Voronezh), shared his opinion about the Vaillant Mag Pro model: “I purchased the speaker more than a year ago, the price was decent, but I wanted German quality. It turned out to be a little noisy in operation, but the heating speed is good, about a minute or even less. I wanted a pure “German”, but the assembly and body are not from Germany. The column with piezo ignition should have been taken with an electronic one, everything else is normal, as stated by the manufacturer.”
Ivan, 43 years old, Urengoy, said: “The Vaillant Mag column was installed two years ago, instead of the old, Soviet model. Semi-automatic model, I really regret that I didn’t immediately take the automatic. When you turn it on, you need to hold the button for a long time until the wick lights up, and it makes an unpleasant noise. Although at full load it works silently and does its job quite well. There is no storage resource for water.”
Grigory, 32 years old, Belgorod, said: “Vaillant instantaneous water heater
I chose it for a long time, installed it more than a year ago. I wasn’t stingy, I bought an automatic machine right away, but there is always hot water in the house, and my hand no longer bothers to press the button. I have two small children, I didn’t feel any restrictions. It consumes little gas, the operation is quiet, there are no noises. It works well because it was initially installed correctly by the service technician.”
Note! The geyser market is replete with all sorts of offers and this is understandable, because the demand for such models is huge. Most large settlements in Russia have already been gasified, and gas heating is much cheaper than electric heating.
Not every speaker pleases the buyer with its performance. In order not to be disappointed, you don’t need much - make a responsible choice and very carefully read the unit’s instructions and user reviews on the Internet.

TOP 5 best manufacturers of geysers
In our homes, hot water is often turned off, and sometimes this privilege, thanks to domestic utility services, is completely absent. Thus, our contemporaries, driven by the desire for savings and comfort, turn to geysers for help. And they are not wrong.
Gas water heaters heat water faster and compete with their electric counterparts in the form of boilers. Therefore, in order to avoid running around the house with pots of boiling water when you are suddenly deprived of hot water, you should get a water heater. If you choose the right place for its location in the house, it will not take up much space, but will be an important, and most importantly, economical object that will warm you and give you peace of mind in case of force majeure.
To help you choose the best speaker for you, we present the TOP 5 best manufacturers of this device, indispensable in any home.
Speakers BOSCH
Our top equipment opens with the German company Bosch, whose traditional and main line of thermal equipment is speakers.
“It’s better to lose money than trust,” said Robert Bosch, the founder of the brand. Adhering to this concept, the company provides the best quality equipment - it was and is one of the most reliable.
The brand is improving and developing the functionality of the speakers, and now you can find a water heater on the market to suit any customer’s requirements. The Bosch line of speakers starts from the inexpensive and practical Therm 2000, a special feature of which is its fixed power and the need for manual adjustment when changing the water flow. And it comes to the practically multifunctional Therm 6000 with an integrated hydrodynamic generator, which allows you to control water heating easily, using just a few buttons on the convenient display of the machine. It is also possible to operate with reduced gas - everything is very economical.
The arsenal of Bosch geysers in the mid-price category also includes Therm 4000 with a closed combustion chamber. The peculiarity of this machine in the presence of forced smoke removal is convenient for houses where there is no way to organize this process in a natural way.
The company offers high-quality devices of different price categories and with extensive functionality. Everyone can find something for themselves in the Bosch line of geysers, which is undoubtedly a plus.
Gas water heaters RODA
By purchasing Roda brand products, you will receive a reliable quality product at a reasonable price. The Swedish company was founded in the 80s of the last century and in a short time gained fame as a manufacturer of high-quality household appliances. Simplicity and functionality are two fundamental criteria in the production of the company’s water heating devices.
- The designs of the company's devices are simple and concise, easily fitting into any interior. All geysers in the line are equipped with a reliable smoke removal mechanism, which is very important, because safety comes first.
- Regarding prices, the company’s line of speakers includes cars for different budgets. The middle of them is the budget and safe JSD20-A4, specializing in working with low gas pressure. Thanks to the open combustion chamber, it demonstrates excellent performance for speakers of this price: it emergencyly turns off the gas in just 30 seconds. The speaker is as compact as possible and installing it even in a small apartment is not difficult.
- The company also took care of producing geysers with a brighter design, so among Roda heating equipment you can find the highlight of the JSD20-A3 line. Compact equipment, a little more expensive than the previous one, but this is paid for by one useful function: the column can be customized “to suit you”, separately controlling power and temperature. Operation is facilitated by a traction control sensor and many conveniences. Of course, its main feature is its appearance with a floral design on the bright black surface of the case.
Buyers note the cost-effectiveness of Roda speakers and ease of use. Reviews about the brand's equipment are positive, with an emphasis on excellent quality at an adequate price.
Gas water heaters VAILLANT
The equipment of the German brand Vaillant is generally an order of magnitude more expensive than previous opponents. However, its attractive, sleek appearance sets the product apart from the rest. The speakers are simple and accessible to use, but with extensive features.
A consumer survey confirms: When buying a Vaillant speaker, the client is confident that this high technology will make life as simple as possible.
The Vaillant line of water heaters includes more budget-friendly and more sophisticated models. Thus, the inexpensive MAG mini OE 11-0/0 RXZ H requires minimal space for location in the house, because the key controls are located on the front panel, equipped with piezo ignition, which greatly facilitates the process of turning on the speaker.
An example of a higher price level is the MAG OE 14-0 geyser. The column has electric ignition, powered by a battery, the charge of which can be checked on the front panel of the water heater.
Tip: The advantages of speakers on an electric lighter are the absence of a ignition wick, therefore the device is advantageous for use with liquefied gas.
The water capacity of Vaillant dispensers is average and corresponds directly to the compact dimensions of the devices. The prices correspond to the high quality of water heaters, which even visually look worth their value. During operation, the surface of the speaker maintains a low temperature, so be sure that you will use your purchase comfortably.
Gas water heaters Gorenje
The products of the Slovenian brand are simple and convenient. Mid-price category, closer to inexpensive. According to customer reviews, the speakers are of high quality and can withstand many years of intensive use.
The less expensive one in the line is the GWH-10NNBW geyser. However, this machine has such important things:
- convenient LED display indicating water temperature;
- exhaust gases are removed naturally;
- automatic electric ignition.
The dimensions of the water heater are average, allowing you to heat more water than compact opponents - the maximum volume of hot water is 10 l/min.
A little more expensive on the list is the GWH-10NNBWC, which has a more luxurious appearance with a grayish panel. The property of this column is to maintain the selected temperature regime during changes in pressure and water pressure. If the flame goes out, the ionized flame control will instantly extinguish the gas. The price for this device is appropriate, but quality and convenience always require the appropriate money, how else?
Gorenje speakers always receive flattering customer reviews regarding the rationality and comfort of their settings. One of the minuses is an important parameter of all geysers - the volume of water heated per minute. Basically, the displacement of Gorenje dispensers is sufficient for one water collection point, but with difficulty for 2-3.
Turning on devices
The Exclusiv RXZ/RXI model has two types of ignition at once: pmi 2013 electronic and piezo. The unit has 10 power levels. Burner modulation is automatic. This ensures a constant temperature at the outlet.
The volume of water heated per minute is 14 liters.
AtmoMAG pro has piezo ignition and two power levels. In a minute - 11 liters of water.
How to light a Vaillant MAG pro gas water heater? Subject to all the criteria for igniting a device with piezo ignition.
One way or another, when igniting a device with a piezo component or electronics, you must follow the instructions.
Briefing
When operating equipment that uses gas, certain instructions must be followed. And Vaillant geysers are no exception.
Almost all of them have piezo ignition. Therefore, it is important to turn on the water before starting them.
There are models with an automatic ignition system. They need to be enabled according to the following algorithm:
- Connect power. To do this, the necessary component is inserted into a special compartment.
- Open the gas valve.
- Turn on the hot valve. It will automatically ignite the burner.
Safety criteria are also important:
- The device should not be lit if there is no traction.
- Do not make changes to the speaker design yourself.
- If you smell gas, immediately block the gas supply and call a specialist. And in such a situation, do not turn on electrical appliances.
How to use a Vaillant boiler
The internal structure and design are thought out to the smallest detail. The instructions describe in detail the principle of adjusting the column using a mechanical control unit. The left knob changes the gas supply to the burner, the right knob controls the water flow.
In boilers with a modulating burner, the water heating temperature is set. After this, the water heater independently changes the heating intensity depending on the pressure in the supply water supply.
Setting up a Vailant gas flow column with a classic burner is done by changing the water flow rate and combustion power. The manufacturer strictly prohibits adjusting the heating intensity by mixing cold water.
Problems and solutions
Vaillant speakers can also suffer from malfunctions. Their reasons may be:
- Incorrect installation and connection.
- Ignoring instructions.
- Lack of water supply.
- Insufficient gas supply.
- Blockages.
- Manufacturing defects.
The following are the most common problems and how to fix them:
- The column does not light up when the water tap is opened. The reason is that this tap is clogged. Maybe the water membrane is worn out or the control unit has failed.
Correction: set the adjustment knob to the minimum value.
- If the filter is clogged, it must be removed and washed. If the mesh in the valve is cluttered, it needs to be unscrewed and cleaned.
- The column overheats and the gas goes out. This triggers the device’s self-defense at extreme temperatures.
This requires special diagnostics. Her methods:
A) If the color of the light is red, then the nozzles are not suitable for this type of gas.
B) If water stagnates in the heat exchanger, then you need to clean all connecting nodes.
C) If there is a lot of scale, it is immediately completely removed.
D) If the water does not heat up well, soot has filled the heat exchanger or the entire apparatus. This requires a thorough cleaning.
D) After starting the device, claps sound. This gas-air mixture detonates in the combustion compartment. It is necessary to change the servomotor, solenoid valve or clean the ignition wick.
E) When the device operates, it produces a lot of black soot. It's the air that's moving incorrectly. cash advance businesses The vector of its movement should be adjusted. The setup is simple - thoroughly clean the column.
Characteristics and features of using Vaillant geysers
A gas water heater is a flow-through gas heater.
The water it heats is used for domestic purposes. The Vaillant geyser can confidently be called a reliable device; it has exemplary German quality and is quite easy to operate. The manufacturer offers a lot of device models, which can vary in power, performance and, of course, cost. Before purchasing, each buyer should become familiar with the operating principles of the device, its design, as well as the problems that often arise during operation.
How to turn on a gas water heater with Piezo ignition?
The next, most common option is piezo ignition
.
You just need to press the button and the piezoelectric element will produce a spark that will automatically light the wick. Some manufacturers have begun to produce geysers with
a fully automatic burner activation system.
Interesting materials:
Why is high pressure created in the cooling system? Why does spathiphyllum bloom green? Why does the water in the aquarium immediately become cloudy? Why did the orchid leaves turn yellow? Why did geranium leaves begin to turn yellow? Why does the starter spin but the car won't start? Why won't steam download? Why doesn't Steam see cs go? Why does the Indesit washing machine take a long time to wash? Why doesn't the washing machine speed up?
Peculiarities
The Vaillant Group produces goods in this category in Germany. Today this water heating installation can be called one of the best in the world. All devices are considered adapted for use in Russian conditions, so they can save resource consumption.
Vaillant operates completely silently. At the same time, the equipment has an attractive appearance and does not heat up from the outside. The main advantage of these geysers is their low cost. Positive characteristics also include efficiency and environmental safety. Savings are caused by low burner consumption and low energy prices.
Among the disadvantages of these devices, it is worth noting the inflated prices. In addition, if the column breaks, finding spare parts will be extremely problematic.
There are few service centers for equipment repair.
Principle of operation
Vaillant heats about fourteen liters of water per minute. They are often used for installation in residential buildings and apartments.
The way they work is quite simple.
- Heat exchanger. This is a plate-type element, which is located near the combustion chamber. The water supplied through the heat exchanger passes through the pipe, at which time it is heated from the walls of the chamber.
- Burner. It performs an important function by ensuring combustion in the chamber. Typically the element is made of stainless steel, but some models may use an alloy of chromium and nickel. There are two types of burners - constant power and modulating. The former do not have automatic heating control. But you can easily set it on the panel, and then the device will independently maintain the temperature. Modulation ones are able to automatically respond to changes in operation. Many models have a temperature detector that can adjust the power to a constant temperature.
- The combustion chamber. This is the so-called unit that is designed for fuel combustion. The apparatus can contain two types of these elements: open and closed. Open is an open type structure within which gas combustion occurs. The air that supports the flame comes from the room. A device of this type uses natural draft, so a chimney must be installed. The closed one has a higher efficiency. It can be of a turbocharged type, with parts being fixed that can create artificial thrust. Such devices feature chimneys of the coaxial type.
- Ignition system. To start the device, you need to ignite the burner. A piezo ignition system works by converting mechanical action into a spark. When the speaker is turned on, a button on the body is pressed and the piezoelectric element is activated. This part produces a spark that ignites not only the soldering iron, but also the central burner. Models that have electronic ignition are the most convenient to use; to start the speakers, just open the tap.
- Automation. Geysers are equipped with automatic equipment, making their use simple and comfortable. Such elements include traction sensors, water pressure control detectors, thermocouples, and hydraulic valves.
Models
This brand sells models with different technical characteristics. The main difference between the devices is their power. It is this indicator that can determine how much water will be heated per minute.
The thermal power of devices from this company ranges from ten to twenty-five kW.
When choosing a geyser for domestic purposes, you should pay attention to the following parameters:
- power, which determines the heating rate;
- ignition option, which can be automatic or semi-automatic;
- burner characteristics;
- method by which combustion products are removed.
Let's look at the most popular Vaillant models.
MAG OE 11-0/0 XZ C+
This model is characterized by excellent characteristics and an affordable price. This is a reliable device that has a power of 17.5 kW, heats eleven liters of water per minute and can start at fairly low pressure. The design of the model is quite simple; on the front panel there is a viewing window through which the flame is controlled. The device body is made of steel and is mounted on the wall.
The disadvantage of the model is its dimensions.
AtmoMAG exclusive RXZ/RXI
Characterized by piezo ignition and electronic ignition. The column is equipped with ten power levels. The burner modulation is automatic, which ensures a stable outlet temperature. The device has an LED indicator, a draft sensor and a copper heat exchanger. In one minute, the column can heat fourteen liters of water.
Disadvantages: short service life, expensive repairs.
Atmomag exclusive GRX
Ignition in the device is provided by a built-in generator, the burner is self-modulating, power comes from an internal generator. The device is mounted on the wall.
Reviews from experts say that this model is not the best option. The hydrogenerator constantly breaks down, which is expensive to repair.
AtmoMAG pro
It is characterized by piezo ignition, has two power levels and heats eleven liters of water per minute. It is often used to consume hot water for domestic needs.
Disadvantages - it only works with strong water pressure, leaks are possible.
Burner
The gas burner is the “heart” of the column. The temperature difference at the outlet, the power of the device and efficiency depend on the principle of its operation.
The power of the column determines how many liters of water the burner can heat in a minute. The indicator is measured in kW. For a single point of use, 17 kW is sufficient, which is about 10 l/min. If you need to open several taps at once, then choose devices with a capacity of 13-15 l/min (from 20 kW).
The stability of the hot water outlet temperature depends on the ability to regulate the burner power. Modern models use 3 options:
- stepped;
- smooth;
- auto.
In the first case, the flame power and water temperature are reduced using a special regulator. The setting is performed with a knob around which a scale is drawn, and the user is guided by it.
In the second option, the flame is also reduced using a manual regulator. Both methods are not very convenient, since the water temperature can change under the influence of various factors.
With automatic adjustment of the burner power there are no such inconveniences. Everything is monitored by special sensors that troubleshoot problems in a timely manner. A column with flame modulation automatically maintains the set water temperature.
Manual
Any device that uses gas must be operated with care. Devices with piezo ignition are quite easy to turn on. But before starting a column of any type, it is important not to forget to turn on the water.
Devices that have an automatic ignition system are switched on according to the following scheme:
- an element for connecting power is inserted into a special compartment;
- the gas valve opens;
- The hot tap turns on, which automatically ignites the burner.
Sometimes a plug of air may form. This usually happens during the initial startup of the equipment or if it has not been used for a long time. You can correct the situation by igniting it several times in a row.
Using Vaillant geysers is not difficult, but do not forget about basic safety rules:
- do not ignite the burner in the absence of draft;
- if you are using the design for the first time, first read the instructions;
- there must be fresh air in the room where the device is located at all times;
- You should not change the design of the device yourself, as this is quite dangerous;
- if you smell gas in the room, you must immediately turn off its supply and call the gas service;
- Also, if there is a smell, it is strictly forbidden to turn on electrical appliances.
Possible problems
Whatever the geyser, it can fail.
Malfunctions may occur due to the following reasons:
- incorrect way of installing and connecting equipment;
- failure to comply with the instructions for using Vaillant devices;
- improper use process;
- lack of water supply;
- weak gas supply;
- column clogging;
- long work without cleaning;
- presence of manufacturing defects.
Let's look at the most common breakdowns and how to fix them.
The column cannot be ignited while opening the water tap
Most likely, a clogged water tap is to blame in this situation. This problem can also arise due to wear of the water membrane, failure of the servomotor or control unit.
You can correct the situation yourself.
- Set the adjustment knob to minimum. Turning the knob helps to reduce the water pressure, as well as increase the water pressure, which can cause the device to start working.
- If the filter is clogged, it must be dismantled and washed.
- If the mesh in the faucet is clogged with scale or debris, then it should be unscrewed and cleaned.
The gas goes out and the column overheats
Thus, the geyser prevents an emergency situation when high temperatures can lead to bursting of the walls in the heat exchanger.
Diagnostic methods:
- if you notice that the color of the flame is red, then most likely the nozzles in the device are designed for a different type of gas;
- if water has a weak flow and can linger in the heat exchanger, then it is necessary to clean all connection points;
- If there is a large amount of scale, it is worth eliminating it to prevent overheating.
Poor water heating occurs
This situation may arise if soot clogs the heat exchanger or the column as a whole. Thorough cleaning will help improve the operation of the device, and you can also replace the membrane.
Sometimes poor heating of the liquid occurs if the water connection hoses are installed incorrectly.
Gas equipment goes out and turns off on its own
In order to correct the situation, you can check the water heater and, if necessary, repair it. The reason may also be faulty spare parts or poor quality assembly. Then it’s worth purchasing a repair kit and correcting the situation.
Popping noises are heard after turning on the equipment
This happens if there is detonation of the mixture of gas and air in the combustion chamber. If the column stops working, the chamber has filled with gas prematurely. The problem can be solved by replacing the servomotor or solenoid valve, as well as by cleaning the ignition wick.
The equipment smokes and forms black soot
To ensure proper air flow, it is worth cleaning the gas equipment. This situation usually happens during the cold season.
There is a water leak in the heat exchanger
This happens if the hoses are poorly connected and the spare parts are worn out. Accordingly, it is worth replacing broken parts and repairing the heat exchanger.
No matter how expensive and reliable the equipment is, it tends to break down and wear out. The middle light does not light up, does the equipment make unusual sounds, does not turn on or goes out spontaneously? All this can be caused by a number of reasons listed above. To ensure that such situations occur as rarely as possible, equipment needs to be treated with care, as well as regular diagnostics.
