German representative of heating equipment - gas boiler "Vaillant"

About company

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 "Vailant" dates back to 1874. The company received its name in honor of the founder - Johan Vailant. The company is the leader in the number of wall-hung boilers sold. She, unlike competitors, offers technology that works with renewable energies. Today the brand owns 27% of the world 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 colossal research and development resources.

What are they?

Boilers are distinguished according to the installation method:

• Wall mounted. Small size and weight. They do not require a separate room. Stylish design - looks great in the kitchen. The described brand offers a large selection of hinged-type models.
• Outdoor. More bulky. More powerful than wall-mounted counterparts. Suitable for heating a large house. There are only three floor 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 - by means of fans. A capacitive boiler can be connected. 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 the number of contours:

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

By the method of removal of combustion products:

• Traditional chimney. Models with an open firebox are called atmospheric. Their labeling is AtmoTEC.
• Coaxial chimney. Closed firebox. Marking turbocharged versions - TurboTEC.

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

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

Connection and setup instructions

The unit is installed on a solid wall with sufficient load-bearing capacity. The place of installation is chosen so that there is the possibility of connecting communications and power supply, access to the boiler for regular maintenance, as well as the possibility of installing and leading to the street of a coaxial chimney.

The connection of the corresponding pipelines is carried out using special connectors that come with the unit.

It is necessary to carefully monitor the absence of leaks of water or OM, as well as the tightness of the gas pipe connection.

The initial setting of the boiler is a rather complicated procedure that must be carried out by a qualified technician.... The user is only required to set the required parameters of the coolant temperature.

These actions can be performed at any time, since the current setting is constantly changing and corrected during operation.

The lineup

The hinged type of equipment remains the most popular option, therefore the German manufacturer offers a wide range of such devices.Products for Russia and Eastern Europe are assembled in Slovakia - the company recently launched its production here. Boilers assembled in Slovakia are marked with the particle "Int". In factories located in Germany, only condensation-type modifications are assembled - Vaillant ecoTEC plus.

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

• AtmoTEC - natural air circulation. 3 versions:

- Pro VUW - dual circuit. Power is 24,000 watts. They are considered budgetary.

- Plus VUW - 20-28 kW.

- Plus VU - single-circuit. At 24,000 and 28,000 watts.

• Allant TurboTEC - air supply by fan.

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

• TEC Plus;
• Turbo FIT;
• TEC Pro.

The "Plus" series differs from the "Pro" by the presence of a "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.

Benefits

It is convenient to consider the advantages of Vilant heating equipment on the example of one model - turboTEC pro VUW INT. This is the most requested modification. It has two circuits and forced gas evacuation. Benefits:

• Modulating burner - a saving factor.
• Power regulation 9,600-24,000 watts. Hot water is enough for 2 points of water intake.
• Expansion tank - 6L. It is possible to arrange 2 circuits for two heating systems.
• Closed firebox.

The efficiency is 93%.

• The copper heat exchanger has a "Suplar" coating for increased durability.
• A flow-through system is used - reduces deposits.
• There is a self-diagnosis.
• Possibility of pump speed regulation. However, the adjustment is done mechanically.

Disadvantages:

• High prices. German quality in this case is estimated at 40,000-100,000 rubles.
• Volatility. To ensure uninterrupted operation of the equipment, you have to connect a UPS - an uninterruptible power supply, battery or generator.
• Noise during operation.

Advantages and disadvantages of Vilant gas boilers

Advantages of Vilent gas boilers:

• the main advantage of Vilant boilers is their reliability. The manufacturer is confident in the quality of its products, therefore the warranty period for all models is 15 years;
• thoughtful design provides a high coefficient of its efficiency - about 94%;
• the equipment is convenient in operation, it does not require constant monitoring, thanks to built-in automatic systems. It is enough to set the required temperature for the boiler to maintain it constantly;
• high degree of reliability, it is provided by automatic electronic systems;
• R
  pressure regulator - stabilizes the operation of the burner in case of gas pressure interruptions;
• thrust sensors - turn off the boiler if it is absent;
• ignition system - closes the gas supply valve, if the flame on the burner has gone out, allows ignition only at the permissible concentration of gas in the chamber, which prevents the possibility of an explosion;
• in case of any malfunction, it is triggered testing system. The appearance of the code assigned to the problem on the screen allows you to quickly fix it without wasting time searching.

Disadvantages of Vilent gas boilers:

• lack of a built-in expansion tank, it serves to maintain the required water level in the heating system. The tank will have to be installed independently if there are interruptions in the water supply;
• in devices with the "atmo" system, the thrust may be insufficient due to lack of fans;
• work of automatic systems of boilers Vilant is impossible without electricity. Therefore, in the event of a network outage, the devices will turn off.

It should be noted that in terms of their efficiency, the Vilant double-circuit gas boilers are significantly inferior to their competitors. Therefore, to reduce the amount of fuel consumption it is recommended turn off the system when leaving, ventilation and reduce the temperature at night.

The disadvantages of these devices include the high cost, which makes them inaccessible to a wide range of consumers.

TurboTec Pro device

Double-circuit devices are equipped with two heat exchangers. The first is made of copper - it heats the coolant, the second is made of stainless steel - for heating running water. The copper heat exchanger has a large number of plates.

The gas burner modulates the flame in the range of 40-100% of the power. There is a built-in hydraulic unit - there is a secondary heat exchanger, a security system, a circulation pump, as well as a variety of sensors.

The main competitors of the brand are German boilers Viessmann. Vailant has an undeniable advantage - water-gas elements are made of high-quality copper, while competitors are made of composite material.

The device is economical in gas and electricity consumption. Thanks to the use of low-voltage equipment, less electricity is consumed.

What series and models belong to the floor

There are three series of Vaillant floor standing boilers:

• CRAFT... Condensing boilers that use additional heating using the heat obtained from the condensation of water vapor from the exhaust gases. They differ in high efficiency, but are designed to work with low-temperature circuits (ideally, underfloor heating systems). The power of the units ranges from 22 to 280 kW, all of them belong to the group of single-circuit units. High prices and restrictions in heating mode limit the distribution of boilers of this series.
• VIT... Single-circuit condensing units with a capacity of 18-40 kW. Equipped with a modular burner with the ability to adjust the flame in the range of 28-100%.
• COMPACT... Double-circuit units with modulating burner. Power - 25, 28 and 30 kW.

Each series has a fairly wide range of units of different power, which allows you to choose the most suitable sample for the existing working conditions.

Price range

German gas equipment is an example of quality, and the price corresponds to it. Boilers of this class cost at least 45,000 rubles. And these are the lowest-powered versions, the more powerful ones are twice as expensive. How much a boiler costs depends on several factors:

• Burner type.
• Smoke extraction method.
• The level of automation and packaging.
• Power.

Installation of "Vailant" devices allows saving 30-40% of gas, therefore, it will fully pay off in 2-3 heating seasons.

Specifications

Consider the general technical characteristics of Vaillant floor standing boilers:

Operation and maintenance

Vaillant devices are reliable and unpretentious, they only need to be connected and configured correctly - then in the future the role of a person in their work will be minimized. The package contains a passport and instructions, which show the connection diagram and device device.

By analyzing breakdowns, the manufacturer adjusts the design and control. Most of the possible problems are discussed in the instructions, here it is indicated how to fix them. 80% of breakdowns are repaired on their own - without the intervention of specialists.

Installation features

Installation of gas devices must comply with the manufacturer's instructions and SNiP. Room requirements:

• The connection room must be fenced off from the living rooms by a door.
• The dimensions of the room depend on the type of firebox. For turbocharged versions, the minimum area is 8 sq. m. Appliances with a closed firebox can be built into furniture.
• AtmoTEC absorb air from the room - ventilation is mandatory and triple air replacement is provided. TurboTEC take air from the street, the requirements for them are less stringent.
• To prolong the operation, a filtration system is installed.

Installation, configuration and first start-up is the task of specialists. The work is monitored by a controller. Before starting the device, a specialist, using special software, checks the operating parameters.
