Vaillant wall-mounted gas heating boilers. Review of Vailant gas heating boilers

Among the offered models heating equipment, wall-mounted gas boiler Vaillant (Vailant), is especially popular. The Vaillant company produces two basic modifications, differing in the type of combustion chamber, the principle of air intake and the removal of combustion products.

Description of the design of Vaillant wall-mounted boilers

The company offers consumers atmospheric and turbocharged wall-mounted gas Vaillant boilers, in the atmoTEC and turboTEC series. Models differ technical characteristics, operating parameters and operating principle.

There are several performance indicators and characteristics common to each type of boiler equipment:

• Technical characteristics of gas wall heating boilers Vaillant– in each series, models are presented with power sizes from 12 to 36 kW, with one or two heating circuits.
  The boilers are equipped with a burner with the ability to partially adjust the operating mode. Modulation occurs within 30-100%. The burners automatically adjust to the parameters of the heating system. Capable of operating at low gas pressure for the boiler, which makes it possible to connect to the central line, or.
• Operating mode – boilers operate in low-temperature heating conditions. The optimal coolant temperature is 60-70°C. Automation is capable of simultaneously regulating several heating circuits: radiator system and heated floors. It is possible to switch to high-temperature heating mode with a certain loss of thermal efficiency.
• Efficiency of wall-mounted gas boilers Vailant– thermal efficiency ranges from 92-108%. In normal heating mode, coefficient useful action decreases to 92-95%.
• PLUS and PRO series – atmospheric and turbocharged boilers, available in each modification. The difference between the PLUS and PRO series lies in several parameters:
  1. Models with the PRO brand have a minimum economy class configuration.
  2. The PLUS modification is distinguished by improved automatic design, a decorative body, and an autodiagnostic system.

The operating principle of the wall-mounted gas boiler Vailant ensures almost complete combustion of gas, due to the fact that the optimal proportions of the gas-air mixture are automatically selected. Economical fuel consumption, especially noticeable when burning bottled gas.

Atmospheric boilers Vaillant atmoTEC

atmoTEC series, equipped with an open burner. Atmospheric boilers have a simple and at the same time effective internal structure. The models are presented in two series, differing in parameters and thermal characteristics:

AtmoTEC series boilers burn air taken from the room during operation. Designed for connection to a classic vertical chimney. During installation, they are presented to the boiler room.

Vaillant turboTEC turbocharged boilers

Installation of Vaillant gas wall boilers with closed camera combustion involves forced air intake and removal of combustion products. For this purpose, a blower fan is used - a turbine. It is for this reason that boilers are called turbocharged.

In the turboTEC series, two modifications of boiler equipment are offered:

The Vailant turbocharged wall-mounted gas double-circuit boiler with a closed combustion chamber fully complies with sanitary standards and technical specifications for installation in an apartment in a multi-storey building. During operation, the turbine emits a uniform hum. Noise indicators will need to be taken into account when deciding where to place the mounted boiler equipment.

According to the technical documentation supplied by the manufacturer, cascade activation is not provided in the turboTEC PLUS and turboTEC PRO series. If necessary, an external room thermostat is connected to the control unit.

How to choose a Vaillant wall-mounted gas boiler

When selecting a suitable heater, pay attention to several thermal characteristics and parameters:

• Features of a heated building - technical conditions in apartment buildings, will not allow installing a boiler with atmospheric camera combustion. For an apartment, models from the turboTEC series are optimal.
• Functional purpose:
  1. Wall-mounted gas single-circuit boiler Vailant is installed in rooms where there is no need to heat hot water, or it is planned to additionally connect a boiler indirect heating. Heaters with one heat exchanger are characterized by high performance, therefore, they are used for heating large buildings.
  2. The Vaillant wall-mounted gas double-circuit boiler satisfies the room's need for heat and the residents' need for hot water supply. The heat generator heats the water using a flow method. IN summer time years, the boiler operates on the principle of a conventional gas water heater.
• Modification - the main difference between the PLUS and PRO series lies in the installed equipment and the degree of automation:
  1. PRO models are equipped with the equipment necessary for work, without any special “frills”.
  2. PLUS series, provides maximum comfort operation, equipped with weather-dependent automation and other useful devices.

After determining the basic operating parameters, the device is selected according to power and price range.

How to calculate what power a boiler needs

The easiest way is to calculate a wall-mounted single-circuit gas boiler Vaillant. For this, the formula is used: 1 kW = 10 m² + 10% reserve capacity in case of extreme cold. Calculations will help you find the approximate power value, given the average thermal insulation of the building and a ceiling height of no higher than 2.7 m.

If the heated area is 100 m², an 11 kW boiler will be required. There is no standard power size in the model range that exactly corresponds to the result obtained. Therefore, a boiler is selected with a capacity rounded into big side. For indoor use, turboTEC plus VU / 5-5 at 12 kW or an analogue with an atmospheric combustion chamber is optimal.

Define required power a boiler with two heat exchangers is a little more complicated. When calculating, take into account the consumption of thermal energy for DHW heating. Typically, another 15-30% is added, depending on the actual needs of residents for hot water.

For a room of 100 m², you need a wall-mounted double-circuit gas boiler Vailant, with a capacity of 10 kW + 10% power reserve + 20% average DHW value. In total, it turns out that 13 kW will be enough. We round the power up. You will need to purchase a 15 kW boiler.

Price range for mounted boilers

Prices for wall gas boilers heating Vailant, standard for equipment of this class produced by a European manufacturer. You can buy the boiler you like starting from 45 thousand rubles. and higher.

Several factors influence the price:

1. Burner type.
2. The principle of removal of combustion products.
3. Degree of automation and equipment configuration.
4. Power.

If we take into account that heating costs after installing Vailant boilers will decrease by 25-40%, the full payback of the equipment will be achieved in 2-3 heating season.According to the manufacturer's instructions, self-installation absolutely not recommended. During the installation process, it is easy to damage the equipment, which leads to malfunction and is the reason for failure warranty service. Installation work may be carried out by a representative of the manufacturer's company who has the appropriate license.

General requirements for installing Vaillant wall-mounted gas heating boilers:

• Automation is sensitive to voltage drops in the network. Boilers are energy-dependent and cannot operate without electricity. The connection is made by and.
• Grounding – to prevent potential dangerous situations and avoiding breakdown of expensive equipment, is mandatory for each boiler model, regardless of the type of burner device.

The design of the project and its approval proceeds practically without problems, all equipment is certified by Rostekhnadzor and has a sanitary and hygienic certificate indicating compliance with all standards and specifications in force in the Russian Federation.

Requirements for the boiler installation location

Installation of a Vaillant gas wall-mounted boiler is carried out in accordance with the manufacturer’s instructions and the standards in force in the Russian Federation. , detail the requirements that apply to the boiler room. In particular, it is indicated:

• Connecting the Vailant wall-mounted gas boiler to the heating system is carried out in any technical room, fenced off from living rooms and the corridor, the door. Installation in guest and residential premises (rooms, kitchen-living rooms, etc.) is not allowed.
• The size of the room used for the boiler room is calculated separately, depending on the type of combustion chamber. The minimum room area for installing a turbocharged boiler is 8 m². According to current standards, it is allowed to build boiler equipment with a closed combustion chamber into furniture, close decorative panels removable type.
• The exhaust of combustion products and air intake differ depending on the selected series. atmoTEC models, during operation, burn air taken from the boiler room, which requires mandatory installation supply and exhaust ventilation and ensuring triple air replacement.
  There are fewer requirements for the turboTEC series, since combustion products are removed forcibly and air taken from the street is burned.
• Boiler piping - for connection to the heating and hot water system, separate outlets are provided, clearly marked in the operating instructions. For long-term operation of the unit, it is necessary to install a water treatment and filtration system.
• The first start of the boiler - the operation is controlled by a microprocessor controller. Before starting the heat generator, a specialist, a company representative, using special software, checks the operating parameters of the device. The gas supply is adjusted, depending on the type of fuel (main gas has a higher pressure than liquefied gas). The optimal operating mode with maximum heat transfer is selected and at the lowest cost for gas

If the heater installation and settings are performed by a company representative, the actual gas consumption does not differ from that indicated in the technical documentation. Significant deviations from the norm indicate that errors were made during installation or the boiler needs servicing.

How to organize gas removal from boilers

Mounted gas equipment Vaillant is produced in the atmoTEC and turboTEC series, and for each modification, there are its own nuances for connecting to the smoke exhaust system:

• atmoTEC series – connects to a classic single-pipe chimney. Installation work is carried out in compliance with existing requirements regarding fire breaks. When passing through floor slabs or roofing, a special cutting is used.
  To improve draft characteristics, a deflector is installed on the chimney head. Decorate the pipe decorative items, is strictly prohibited.
• turboTEC series - smoke removal device is carried out using a coaxial chimney. Removal of combustion products, forced. It is carried out by pressurizing a turbine.
  The smoke exhaust system is connected to a coaxial chimney. The horizontal length of the pipe should not exceed 3-5 m. A wind protection and condensate collector are installed on the head.

The boilers are equipped with a pressure sensor that stops the operation of the boiler in case of insufficient draft parameters. To ensure the operation of the boiler, the connection of the smoke removal system is carried out in strict compliance with the manufacturer’s instructions.

Thermostat for wall-mounted boiler

Room thermostat is not included basic equipment and is purchased separately. Real-life operating experience shows that after installing a temperature control sensor, the following benefits are achieved:

• Savings are on average 10-15%. Cost-effectiveness is achieved due to the absence of overheating of the room. The boiler does not focus on heating the coolant, but on the air temperature in the living room.
• Ease of management– to change operating settings, you do not need to go to the boiler room. All changes are made using a remote control unit, installed at the customer’s request in any room.

If necessary, it is possible to install several thermostats at the same time.

Features of operation and maintenance of wall-mounted boilers Vailant

In general, German mounted gas heating boilers Vailant are unpretentious and reliable heating equipment. Once connected and configured, it requires minimal human intervention.

The manufacturer analyzes all cases of breakdowns and makes changes in design and management. Most malfunctions and methods for eliminating them are described in the operating instructions. In 80% of cases, using the manufacturer’s recommendations, it is possible to independently eliminate the cause of the boiler failure.

In internal structure boiler, a self-diagnosis system is installed that automatically checks the heating system and performance. Information about faults is displayed on the display and stored in the controller’s memory. The collected data makes it easier for the specialist during service, find problems and determine best way eliminating them.

What is the service life of a Vailant boiler?

The manufacturer states that on average, boilers will last from 12 to 15 years. Service life and operation are largely related to compliance with the manufacturer’s recommendations and the absence of violations during installation.

The warranty applies to the boiler if the following instructions are observed:

• Maintenance frequency– regular checks of system performance are carried out before each heating season. Every two years, a heat exchanger follows.
• Coolant quality– the instructions state that heat exchangers are sensitive to aggressive environment. The use of non-freezing coolant (antifreeze) is prohibited. System required.
• Security system– connection to the electrical network is made through a UPS and a stabilizer.

How to remove scale from a boiler

Every two years, maintenance of the Vaillant gas mounted boiler is carried out, with mandatory flushing of the heat exchanger and descaling.

Work is carried out in several ways:

• Household methods - scale is removed with citric acid, or chemicals for home use.
• Professional cleaning– in specialized workshops, scale is removed using ultrasonic or mechanical impact. In the second case, a special “booster” device is used. A chemical composition is poured into the cavity of the device, in an action reminiscent of a pump. The pump drives liquid through the heat exchanger, cleaning it of scale.

How much gas should a wall-mounted boiler consume?

Calculation of gas consumption is carried out according to the standards specified by the manufacturer in the technical documentation. The atmoTEC series consumes 0.11 m³ per kW for heating; the turboTEC series has a coefficient of 0.1 m³. When working in full power, for a 100 kW house, you will need about 300 m³ of gas per month. This ratio may be influenced by several factors:

• DHW – with high consumption of hot water heated by flow-through method, gas costs increase by 30%.
• Cold winter - the expected increase in fuel consumption will be about 40-50%.
• Incorrect gas flow adjustment– mainly observed when self-installation gas boiler. Expected excess fuel consumption is 15-20%.

Comparison of boilers Baxi, Vaillant, Protherm, Viessmann - which is better?

Before you start comparing specifications different brands heating equipment, you should pay attention to the main disadvantage of the Vaillant wall-mounted boiler - the lack of accurate information about the country of manufacture of the boiler equipment. Often, you can hear feedback that German boilers, in fact, made in China.

Vaillant wall-mounted boilers are, indeed, assembled in China. But products manufactured in the “celestial kingdom” are available exclusively to residents of that region. Domestic consumers are offered equipment manufactured exclusively in EU countries: Türkiye, Slovakia, France, Germany. Moreover, where Vailant wall-mounted gas boilers are assembled has absolutely no effect on product quality and performance characteristics.

As for other operational characteristics and parameters, it is better to focus on reviews from owners about the use of wall-mounted gas boilers from the brands Vailant, Protherm, Viessmann and Baxi. Among the presented brands, the championship is occupied by.

Second place in popularity, reliability of assembly and ease of use, shared German Vaillant and Czech Protherm. The assessment was also influenced by the number of service centers and requests from owners. The third place in reliability and popularity remains the Italian Baxi.

Most heat consumers are familiar with the Vaillant brand. This brand produces modern and reliable heating equipment. Such devices are designed for those who want to purchase high-quality devices from trusted manufacturers. Double-circuit gas boilers “Vaillant” are distinguished by high performance and long service life. The Vaillant wall-mounted gas boiler should be chosen very carefully. The efficiency of the home heating system will depend on this.

Boiler features

The use of the heating system must be reduced to pressing the unit's power button. Also, when operating a gas boiler, it is necessary to set a certain temperature. However regular checks settings and permanent repair work there shouldn't be. Operation of the device will be problem-free if you purchase a double-circuit boiler from the popular Vaillant brand. His homeland is in Italy.

Equipment of this brand has been produced in Russia for more than 20 years. It is quite difficult to find competitors who are ready to offer products of the same quality. This explains the wide popularity of Vaillant gas boilers.

It is worth highlighting several main features of such products:

Also, such products have a large number of useful functions. Thanks to the large range of heating equipment, the consumer can choose both a budget product and a boiler from a more modern series.

The German company Vaillant is a world-famous manufacturer of heating equipment. A special place Its product range includes the category of gas-fired boilers. On Russian market The company offers a fairly wide range of its products. But what’s surprising is that the company has been developing, producing and selling gas boilers for more than a hundred years, and the equipment came to Russia only 15-20 years ago. But the Russians were immediately convinced that the Vaillant gas boiler is a modern unit, with all the ensuing consequences.

Currently, the manufacturer offers two positions:

• Wall-mounted (single-circuit and double-circuit).
• Floor-standing (single-stage and two-stage).

Attention! The “Wyland” floor-standing gas boiler must be installed only in a separate room intended for the boiler room.

Wall modifications

Let's start with the fact that wall-mounted gas boilers "Vaillant" marked "VUW" are double-circuit designs, with the help of which both the heating system and the hot water supply system are organized. Marked “VU” are single-circuit models. They have a good power range from 12 to 36 kW. Currently, there are two variations of the wall-mounted heating unit on the Russian market:

• TurboTEC plus VU/VUW, which uses the principle of forced removal of gas combustion products.
• AtmoTEC plus VU/VUW – natural drainage occurs in this design.

Boiler with a closed combustion chamber

But there are also subsections in this category. The prefix “plus” indicates that the boilers of this model are standard designs. But the “pro” prefix is ​​a model of a simplified design. What is their simplicity?

• This is an increase in the time it takes to heat hot water for DHW systems. Time taken up to 5 minutes.
• Circulation pump parameters can only be entered manually. IN in this case This refers to the speed of rotation of the impeller.
• An automatic system for troubleshooting and analyzing the operation of the device is simpler and therefore less effective.
• Power limitation. This subgroup contains Vaillant gas boilers up to 24 kW.

But they have the most low price throughout model line. By the way, boilers of this category are most often used in small dachas or cottages. They are unpretentious in operation and maintenance, take up little space and belong to the “economical” category.

Vaillant in the interior

Floor modifications

1. VIT - this design has a single-stage burner.
2. VIT exclusive – with two-stage burner.
3. CRAFT are powerful units.

What is the essence of the operating principle of a two-stage gas burner and why is it more effective? A gas regulator is installed in the design of any gas burner, which mixes fuel with fresh air. And the better the ratio of these two substances, the more efficiently the air-gas mixture burns, releasing large number thermal energy. In a two-stage burner there are two such regulators, installed in series relative to each other. The mixture acquires the most optimal values.

Vaillant floor-standing gas boilers, like wall-mounted ones, are available in two categories:

• With forced removal of combustion products
• With natural.

The choice of one option or the other depends on design features the room in which the boiler will be installed. If it already has a chimney structure that provides good draft, then without a doubt it is best to install the “ATMO” brand. If there is no chimney, then, of course, “TURBO”. Almost all floor-standing models are equipped with the automatic DIAsystem. With its help, the entire operation of the heating unit is adjusted. The most important thing is to set the necessary parameters at the very beginning of operation of the Vailant gas boiler, which will then be maintained automatically throughout the entire period of operation. If something doesn’t suit you, the operating mode can be easily changed.

Control unit

Currently, like many global brands, the Vailant company is trying to use elements and blocks in its gas boilers that could simplify the control method and make the operation of the unit itself more efficient. For example, remote control and the ability to analyze all processes occurring in the device. The last position is modern approach to solve such a problem as malfunctions of Vailant gas boilers.

• Firstly, with the help of this automation you can track how the boiler operates in different modes.
• Secondly, all this is displayed on the control unit display. You can determine which node works and how it works. For the master from service center it is simply a real assistant that itself diagnoses all the thermal processes occurring inside the boiler.

I would like to add that the instructions for Vailant gas boilers are written in Russian.

Floor design

Model specifications

To specifically understand and understand the technical characteristics of Vailant gas boilers, it is necessary to disassemble just one model, which, according to experts, is the most popular today. This is the Vaillant turboTEC pro VUW INT model - a simplified dual-circuit design with forced removal of fuel combustion products.

Pros and cons

Let's start our analysis with positive and negative characteristics. Advantages:

• An economical option due to the modulated burner installed in its design.
• It is possible to adjust the power from 9.6 to 24 kW. Hot water flow is designed for two taps.
• The volume of the expansion tank is 6 liters. It is possible to organize two circuits for two heating systems.
• This is a boiler with a closed combustion chamber.
• Efficiency 93%.
• The primary heat exchanger is made of copper and coated with a special material “Suplar”, which increases the protective properties of the material.
• Flow system that reduces deposits.
• Self-diagnosis.
• The pump speed can be adjusted, but only manually.
• Two heat exchangers mean that when using hot water for domestic needs, the heating system does not turn off. The primary heat exchanger is copper, the secondary heat exchanger is stainless steel plate.
• Service setup.

Model line

Flaws:

• This is an energy-dependent unit.
• High cost compared to other brands.
• The operating noise of the device is quite high.

In all other respects, this is a truly gas boiler of European quality.

Additional technical characteristics:

As you can see, the Vailant double-circuit gas boiler of the “turboTEC pro VUW INT” brand has good technical characteristics. Of course, this is a simplified design, but it is the one that is most popular among Russian consumers today. And the point here is not the cost of the equipment, although it is the lowest, most likely, it’s all about ease of maintenance, plus one hundred percent adaptation to the difficult Russian operating conditions.

By the way, a special unit is installed inside the boiler, which controls the pressure inside the main pipe. Moreover, a system has been installed that responds to electrical surges. All this ensures continuous and trouble-free operation of the heating installation.

Installation of gas boilers "Vailant"

Nuances of the installation process

Like all brands of gas boilers, Vailant units are quite complex in their internal design heating devices. You can see this by looking at the picture above. It contains a lot of different components and parts. And although the connection requires only four water pipes and one gas pipe, a chimney and an electrical supply system, it is still not recommended to do this yourself.

• Firstly, for this you will have to find specialists with access to this species works
• Secondly, obtain permission (in the new house) to connect gas equipment.
• Thirdly, obtain a certificate that confirms that all work was carried out legally and by specialists.

If at least one of the three above points is not met, then you will definitely have problems with the gas service of the area. So you shouldn't do it on your own. It is better to do everything within the law.

Having visited a store with heating equipment and inquired about the availability of Vailant double-circuit boilers from sales consultants, we will find that we have two types of equipment to choose from - convection and condensation type boilers. The latter have a more complex filling, but are distinguished by increased efficiency and solid efficiency. When compared with traditional models, the average increase in efficiency is approximately 10-12%.

The main disadvantage of any double-circuit boiler Vaillant - a price that hits the buyer's pocket hard. But you have to pay for quality, there’s no getting around it. But you will have at your disposal balanced equipment with a long service life.

An interesting feature of double-circuit boilers from Vaillant is that the manufacturer does not disperse its efforts into dozens and hundreds of models, churning them out one by one. On the contrary, Vaillant welcomes a careful approach to the creation and literally “licking” of each new product created. A boiler from Vaillant is a kind of iPhone in the world of heating technology.

Main models and their prices

Are you planning to purchase a Vaillent double-circuit gas boiler? Then we suggest you familiarize yourself with the main models. There are not very many of them, so we will try to describe them in as much detail as possible.

This is one of the simplest double-circuit models from Vaillant. But the simplicity of the technique is only apparent. In fact, we have before us an advanced turbocharged heating boiler. It is designed to work with a coaxial chimney and is equipped with a closed combustion chamber with forced removal of combustion products. The power of the model range varies from 12 to 36 kW in increments of 4 kW. The device does not require special maintenance and pleases with impeccable operation.

The Vaillant gas boiler is a product of the German company Vaillant, specializing in the production of heating equipment. This is the founder of gas appliances and a recognized leader in the world market. Today the company produces wall-mounted and floor-standing boilers, which are rarely talked about poorly - consumers note their efficiency and high quality assemblies.

The brand is part of the giant Vaillant Group. It sells about three million units annually. The company's annual turnover is 2 billion euros. The history of Vaillant dates back to 1874. The company received its name in honor of the founder, Johan Vaillant. The company is a leader in the number of wall-mounted boilers sold. It, unlike its competitors, offers equipment that works with renewable energies. Today the brand owns 27% of the global market for wall-mounted heating devices. The European company sells its products in almost all parts of the world. The brand, despite the narrow focus of production, has enormous research and development resources.

What are they?

According to the installation method, boilers are distinguished:

• Wall-mounted. Small size and weight. They do not require a separate room. Stylish design - looks great in the kitchen. Described trademark offers a large selection of mounted models.
• Floor-standing. More bulky. More powerful than wall-mounted counterparts. Suitable for heating a large house. There are only three floor-standing models - AtmoVIT (16,000-56,000 W), AtmoCRAFT (65,000-157,000 W) AtmoVIT Exclisuv (up to 47,000 W). Made of cast iron - this extends their service life. Air intake is through fans. You can connect a capacitive boiler. The latest modifications of the floor-standing series are equipped with two burners, one maintains a constant temperature of the coolant, the second is activated when it is necessary to increase the heating intensity.

By number of circuits:

• Single-circuit. They are intended for heating only. Marking "VU". It is possible to connect a boiler.
• Dual-circuit. These, in addition to heating the house, simultaneously heat water for domestic needs. Marking "VUW". The efficiency of such devices reaches 93%.

According to the method of removal of combustion products:

• Traditional chimney. Models with an open firebox are called atmospheric. Their marking is AtmoTEC.
• Coaxial chimney. Closed firebox. The marking of turbocharged versions is TurboTEC.

Also gas heaters Vaillant differ in power and equipment. The manufacturer produces equipment with four powers - 12, 24, 28, 36 kW.

A lot is encrypted in the marking useful information. For example, the Vaillant VU turboTec 362/5-5 marking means one “VU” circuit, turbocharged - turboTec, 36,000 W, 2 - forced smoke removal, 5 - fifth generation.

Model range

Attachable equipment remains the most popular option, so German manufacturer offers a wide range of such devices. Products for Russia and other countries Eastern Europe assembled in Slovakia - the company recently launched its production here. Boilers assembled in Slovakia are marked with the particle “Int”. At factories located in Germany, only condensing type modifications are assembled - Vaillant ecoTEC plus.

Depending on the type of ventilation, wall-mounted devices are distinguished:

• AtmoTEC – natural circulation air. 3 versions:

— Pro VUW – dual-circuit. Power 24,000 W. Considered budget.

— Plus VUW – 20 -28 kW.

— Plus VU – single-circuit. At 24,000 and 28,000 W.

• Allant TurboTEC – fan air supply.

There are 3 main series of 2-circuit VUW boilers:

• TEC Plus;
• Turbo FIT;
• TEC Pro.

The “Plus” series differs from the “Pro” in the presence of “quick start” - thanks to this function it is possible to maintain a constant temperature in the heat exchanger for DHW.

The latest models are equipped with “ATMO GUARD” - a security system based on two temperature sensors.
