The Vaillant gas boiler is a product of the German company Vaillant, which specializes in the production of heating equipment. This is the ancestor 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 badly – consumers note their cost-effectiveness and high build quality.
About Us
The brand is part of the giant concern 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 got its name in honor of the founder, Johan Vaillant. The company is the 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 heaters. 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 like?
According to the installation method, boilers are distinguished:
- Wall. Small size and weight. Do not require a separate room. Stylish design – look great in the kitchen. The described brand offers a large selection of hinged models.
- Floor. More bulky. More powerful than wall-mounted counterparts. Suitable for heating a large house. There are only three floor models – AtmoVIT (16-000 W), AtmoCRAFT (56-000 W) AtmoVIT Exclisuv (up to 65 W). Made of cast iron – this prolongs their service life. Air intake – by means of fans. You can connect a capacitive boiler. The latest modifications of the floor series are equipped with two burners, one maintains a constant temperature of the coolant, the second is activated if it is necessary to increase the heating intensity.
By the number of circuits:
- Single-circuit. They are for heating purposes only. “VU” marking. It is possible to connect a boiler.
- Double-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 furnace. Marking turbocharged versions – TurboTEC.
Vaillant gas heaters also differ in power and configuration. The manufacturer produces equipment with four capacities – 12, 24, 28, 36 kW.
The marking contains a lot of useful information. For example, the Vaillant VU turboTec 362/5-5 marking means – one “VU” circuit, turbocharged – turboTec, 36 W, 000 – smoke is forced out, 2 – the fifth generation.
The lineup
The mounted type of equipment remains the most popular option, so 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 “Int” particle. 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 air circulation. 3 versions:
– Pro VUW – dual-circuit. Power 24 000 W. They are considered budget.
– Plus VUW – 20 -28 kW.
– Plus VU – single-circuit. At 24 and 000 watts.
- 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 series in the presence of a “quick start” – thanks to this function, it is possible to maintain a constant temperature in the DHW heat exchanger.
The latest models are equipped with “ATMO GUARD” – a security system based on two temperature sensors.
Advantages
It is convenient to consider the advantages of Vaillant heating equipment using the example of one model – turboTEC pro VUW INT. This is the most requested modification. It has two circuits and forced venting of gases. Advantages:
- The modulating burner is a savings factor.
- Power regulation 9 600 -24 000 W. Hot water is enough for 2 points of water intake.
- Expansion tank – 6l. You can arrange 2 circuits for two heating systems.
- Closed furnace.
Efficiency-93%.
- The copper heat exchanger has a “Suplar” coating that increases its durability.
- A flow system is used – reduces deposits.
- There is a self-diagnosis.
- Possibility of regulation of speed of the pump. True, the adjustment is carried out mechanically.
Disadvantages:
- High prices. German quality in this case is estimated at 40-000 rubles.
- Energy dependence. To ensure the uninterrupted operation of the equipment, you have to connect a UPS – an uninterruptible power supply, a battery or a generator.
- Noise during operation.
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 within 40-100% of power. There is a built-in hydraulic unit – a secondary heat exchanger, a security system, a circulation pump, as well as a variety of sensors are installed there.
The main competitors of the brand are German Viessmann boilers. Vailant has an undeniable advantage – the water-gas elements are made of high-quality copper, while the competitors are made of composite material.
The device saves gas and electricity. Due to the use of low-voltage equipment, less electricity is consumed.

Reviews
TurboTEC Pro VUW 242/3-3: Konstantin E., Engels
Bought 4 years ago for 35 rubles. Now it’s almost double the price. During the operation appreciated all the pros and cons. I’ll start with the pros – he doesn’t need a boiler room, hangs in the kitchen, doesn’t bother anyone. For heating and hot water – separate valves that can regulate the temperature. There is a screen on which the error code is lit – a hint about the problem. There are also disadvantages. He needs electricity for ignition – if it is turned off, you will be left without heat and hot water. There was also a breakdown, and after the first use, the valve broke, which increases the pressure.
Atmo TEC pro VUW 240/3-3: Marat Zh., Serpukhov
We chose wall-mounted – because it is compact, and double-circuit – because hot water is needed. The equipment is expensive, but it is easy to use – the temperature of heating and water is regulated separately – by valves. There are practically no problems. It only reacts to the kitchen hood – if it works for too long, it turns off. And it shows the error code – F36. The problem is exhaust gases. Have to restart. Another plus is silent operation. Connected to underfloor heating.
Vaillant equipment deservedly occupies a leading position in the ranking of demand, quality and sales volume – these are truly reliable and economical devices. Their only drawback is the high cost, both of the boiler itself and its spare parts, repairs, and maintenance. If problems occur, they are most often associated with improper installation, configuration or operation.
