The Vaillant geyser adequately represents German quality. In the brand's products, the latest technologies are combined with simplicity - constructive and operational. Using such equipment does not cause irritation - it works properly, without reminding itself of breakdowns and malfunctions. Products from Vailant are available all over the world - the company has a wide network of sales offices.
About company
The German brand Vaillant begins its history with the city of Remscheid (Germany), where 140 years ago, engineer Johan Villant opened his own business. Today, the company firmly holds a leading position in the segment of boilers and water heaters. The company has one of the world's largest research and development laboratories in the field of heating equipment. Ten factories of the company are located in Germany, Spain and other countries. The brand has over 60 awards in the field of design, environmental friendliness and consumer qualities. In Russia, the brand is officially represented by dozens of dealers working in all regions.
Gas instantaneous water heaters
Plus heaters from Germany - copper heat exchangers. They are durable and reliable. The burner material is chrome nickel steel. All models have a traction rollover sensor. Productivity of household appliances - 14 l / min. Two options for water heaters are presented:
- Basic version. Power - two steps. Piezo ignition - to turn on the device, just press the button.
- Extended version. 10 power steps. Automatic control of fuel flow and pressure.
In addition to piezo ignition, German speakers can be equipped with electric ignition - ignition is carried out by batteries. It is enough for the user to open the tap with hot water for the device to work.
The brand offers models that differ in technical indicators, the main of which is power - it determines the speed and volume of water heated by the device per minute. Willant produces water heaters with a thermal power of 10-25 kW.
Types of geysers
Flowing gas water heaters are usually installed in small apartments - their capabilities are usually calculated, depending on the model, at 1-2 points of water intake. Connection is made to cold water supply, food - on gas, liquefied or natural. The principle of operation is simple - the water flow entering the heat exchanger is heated by combustible fuel, and immediately sent to the mixer.
Storage heaters are able to heat and collect large water supplies that do not cool in the tank due to the layer of heat insulator. Such devices are bulky, they need a separate room, while flow-through devices are placed in the kitchen, in the bathroom, the main thing is to provide smoke exhaust and ventilation.
Selection options
Choosing a water heater for domestic needs, evaluate it by the following criteria:
- Power. The volume and heating rate depend on it. Nominal values of thermal power - 6-30 kW.
- The method of ignition. Automatic or semi-automatic. Automatic ignition - turn on when water is supplied. Semiautomatic devices are triggered by pressing the piezo ignition button. This is not an economical solution - because of the constant burning of the igniter, gas is wasted.
- Burner option. Characterized by the type of power - it can be constant or simulated. The first is suitable for constant pressure water supply. If the pressure changes in the pipes, the temperature will jump at the outlet. To avoid this, the developers provided a simulated version of the burner - in it the power changes along with the pressure, ensuring temperature stability.
- The method of removal of combustion products. The chimney type is used provided that there is a chimney in the room into which the corrugated sleeve will be withdrawn.
Turbocharged models are inferior in demand to chimneys, since there is a danger that bypasses freeze in frost. You have to regularly drain the collected water to prevent the heat exchanger from exploding.
Dimensions and shape are second-order parameters. Usually you have to consider the dimensions of the room in which you want to mount the device. If the cumulative version does not fit, you should consider installing a flow-through analog.
Model Overview
Who is in the TOP 2017?
Vaillant is a consistent leader in consumer demand ratings. Last year, the brand ranked second in the TOP of the best gas water heaters, second only to the Italian brand Ariston. The modification that took second place in the popularity rating is MAG OE 11-0 / 0 XZ C +. This is one of the most popular modifications. Outperforms competitors in technical specifications, while winning in value. Estimated price of the device, which took the second line of the rating - 11 000 rubles. For an amount comparable to the models of the Chinese assembly, the consumer acquires a reliable column with technical characteristics that ensure comfortable use:

Vaillant Mag - savings and quality
The series is adapted to domestic gas and water supply conditions. The volume of heated water is from 10 l / min. Models are equipped with automatic ignition.
- AtmoMAG exclusiv RXZ / RXI (piezo ignition / electronic ignition). Ten power levels. Thanks to the automatic modulation of the burners, it is possible to ensure the stability of the outlet temperature, regardless of flow. Automatic regulation of gas flow allows you to maintain a constant water temperature if its pressure changes in the water supply. In the RXI version - an LED indicator that displays information about the battery charge, problems and flame recognition. All other design details are similar to the above - a copper heat exchanger, traction sensor, etc. Nominal characteristics: 9.8-24.4 kW, pressure 13 bar. The minimum pressure is 0.2 atm. The device weighs 14 kg. Productivity 5.9 / 14 l / min respectively at 50 and 25 ° C.
- Atmomag exclusiv GRX. Ignition provides a built-in generator. Flow type. Wall mount. Burner self-modulation. The adjustment is similar to the previous model. Power - internal generator.
- AtmoMAG pro. Piezo ignition. 2 power levels. 11 l / min The nominal value of thermal power is 10-19.2 kW. For domestic consumption of hot water.
Security questions
Gas is a high-risk fuel. To protect your home from accidents, you must follow the safety rules for gas-powered equipment. Manufacturers, including the company Willant, took care of safety by providing several degrees of protection that exclude accidents. Pay attention to the organization of the security system. In German columns, the issue is solved by creating several levels of protection using various sensors and relays. Your column should:
- Automatically shut down in the event of interruptions in the supply of water / gas.
- Eliminate leakage.
- Switch off in the absence of traction.
These conditions are met using special sensors that respond to the following parameters:
- Ionization. The system shuts off the fuel supply when the flame goes out.
- Combustion. It is similar to the previous one - it is activated if the ionization sensor does not work.
- Flow. Shutdown when closing the crane.
- Thrust. Prevents poisoning from combustion products.
- Low pressure. The device does not turn on when there is insufficient pressure.
- Overheat. Heating control - as soon as the temperature rises to a critical value, the device turns off. Tearing of pipes is prevented.
A pressure relief valve controls the pressure in the water pipes. If the proposed device does not have at least one of the listed methods of protection, it does not fully meet the security requirements - this is a threat. Vaillant developers have provided all the necessary protection methods.
Damage to gas water heaters Vaillant
Even the most reliable equipment wears out, breaks down, and requires preventative maintenance and repair. Gas-fired water heaters are not an exception. In order not to provoke malfunctions, the user must know the rules for handling the device. To familiarize yourself with the device and the principle of operation, detailed instructions are supplied. Common problems:
- The wick is off. The smoke detector must have broken. Will have to change. Another reason for the extinct wick is that the thermocouple broke.
- Water is not heated. So the heat exchanger is faulty. Here it will not be possible to repair it - only a replacement.
- Overheating, accompanied by noise. It is necessary to check the radiator - if it is clogged with combustion products - clean.
- Heat exchanger leak - change.
- The spark for ignition does not light up. Replacing the flame controller.
Experts do not advise doing repairs on their own - especially for beginners, contact a service center.
Causes of breakdowns
- Incorrectly connected pipes. Installation errors.
- Violation of instructions. Violation of the operating rules - work without water and at low pressure in gas pipes.
- Lack of timely cleaning - wear parts.
- Manufacturing defects. For German heaters - a rare occurrence.
Reviews
MAG OE 11-0 / 0 XZ C +: Daniel T., Podolsk
Great thing. She worked for 5 years. Stably warms - without scalding in the first minute. Even if there is a thin stream in the tap, it still ignites. Works simultaneously on two mixers. But you need to adjust the feed. Used even to fill the pool. I believe that a high-risk device should not be bought cheaply, it took a European and did not lose. Of the shortcomings - in the maximum heating mode begins to make noise. Spare parts are expensive when compared, for example, with the Neva. The walls of the heat exchanger are thin.
AtmoMAG exclusiv GRX. Regina R., Kolomna
Dear thing, it often breaks. Parts are expensive. She worked for 6 years. We will take a new, different company. In the end, this coil eventually dripped. for 6 years, the adjustment knob broke twice. Jumps out temperature. After a year of work, the enamel on the body began to peel off. Rust has appeared. Every year I had to descale, despite advertising some kind of super coverage. No super German quality was noticed.
Despite the advertised German quality, there are many dissatisfied among the owners of the Wyllant water heaters - the equipment did not live up to their expectations. Perhaps this is due to improper operation, or the exactingness of developers to comply with the rules of use, which many users violate. Experts avoid such unambiguous estimates. German equipment complies with European quality standards, surpassing the capabilities of Chinese and Russian counterparts.
