When choosing a gas boiler for heating a country house or city apartment, many people prefer domestic developments to imported ones. Moreover, it is economically beneficial: domestic gas boilers cost much less than European brands.
One of the leaders of domestic manufacturers of household heating equipment is, which produces wall-mounted gas boilers of the luxury series. It is important to note that the technical characteristics of these units are in no way inferior to foreign analogues in terms of functionality, economy and efficiency.
History of the Neva company
Russian users are well aware of the single-circuit and double-circuit wall-mounted gas boiler Neva Lux. But not everyone knows that the company producing such equipment appeared on the market more than 50 years ago.
The original enterprise was called "Gazapparat". It specialized in the production of any gas equipment, including water heaters, boilers, and heaters. Currently, the company belongs to the largest concern “Baltic Gas Company”.
Thanks to this alliance, models such as the Neva Lux and a new product on the market - the Turbo model - appeared. The shortcomings in the work of the first models were taken into account and were eliminated in subsequent ones. As a result, the consumer receives a product of European quality.
Ignition of the column
The column can be ignited in different ways:
The most convenient and popular is electronic ignition. Speakers with such ignition are a little more expensive than others. But they are more reliable and economical. Most often, batteries are used as a power supply.
In piezo ignition, you need to press the button on the panel to ignite the gas. In new models this method is sometimes used.
In modern models it is rare to find manual ignition. Such speakers are practically never produced.
Columns with microturbine ignition are quite expensive. In such models, the current is generated by a hydrodynamic generator that controls the water flow. Such speakers are not difficult to use. After opening the water tap, the gas is ignited automatically. This results in significant gas savings.
Model range of gas boilers Neva
The units produced by Neva are divided into two series: Lux and Turbo. Devices belonging to the Lux series are divided into two categories:
- Single-circuit wall-mounted gas boiler Neva Lux. Intended only for supplying the home with heat. If you connect an indirect heating boiler, then such a unit will be able to provide the house with hot water supply. Due to the fact that the device includes a modulating burner, which can change the combustion intensity based on the specified temperature, the device is highly economical. The boiler operation can be switched to liquefied gas. Neva gas single-circuit wall-mounted boilers have gained wide user demand also due to their low price, simple maintenance, and the absence of volatile components that are subject to voltage drops in the network.
- Double-circuit wall-mounted gas boiler Neva Lux. Such devices have open and closed combustion chambers, as well as a bithermal heat exchanger. The chimney can be either coaxial or traditional. The heating process of the coolant is controlled by highly precise automation. The maximum distortion from the specified temperature regime is no more than 1%. Another key difference between a double-circuit wall-mounted gas boiler is the ability to connect two heating systems at once. There are outlets for heated floors.
If you connect a thermostat, you will significantly reduce gas consumption and the automation will function completely independently. The control unit will automatically adjust the heating of the coolant based on how warm the room is.
Possible faults
The more complex the equipment, the greater the likelihood of it failing. This is especially true for the electronics included in the control system. Despite the fact that Neva Lux heating boilers are considered extremely reliable, some types of malfunctions cannot be avoided. More often for reasons not related to the equipment itself. These include:
- Low gas or water pressure in the system;
- Breakage and attenuation of the flame;
- Mechanical breakdowns.
The built-in self-diagnosis system displays an error code on the display, which is identified by the table on the last page of the instructions. If there is no warranty, you can fix some simple malfunctions yourself, but it is still better to contact the manufacturer’s customer support service or directly to the service center.
Boiler Neva Turbo
Users left various reviews about the quality and ease of use: positive and negative. Over time, all the necessary adjustments resulted in the production of a separate series of heating devices. Neva Turbo units are, by and large, a modified version of the already familiar Lux series.
Boiler Neva TURBO 24
All shortcomings were taken into account here. The technical characteristics of the models are as follows:
- closed combustion chamber - here there is a forced air supply through a fan.
Smoke removal is carried out using a special device through a coaxial chimney; What are gas boiler fans needed for and what types they are, you can find out in this article - automation - wall-mounted gas double-circuit boiler - Neva Turbo is fully adapted for operation. A multi-level system of sensors and valves is responsible for the safety of equipment operation and heating regulation. The package includes an autodiagnostic system, which automatically carries out a test, the results of which are displayed on the liquid crystal display;
- control is on regular buttons. Using a conventional regulator, you can set the desired temperature mode, provided that the programmer is installed, you can select operating conditions for several days or a week. The additional kit includes a room thermostat. The sensor issues a signal to turn off the heating when the room is heated to the desired temperature.
Turbo boilers are energy-dependent units. Electrical power to the boiler is achieved by connecting to a regular voltage network of 220 V.
How to light a speaker with piezo ignition
You can find out complete information on the selection, operation and maintenance of gas water heaters (instantaneous water heaters) from all manufacturers if you go.
In addition to specific information on the site, you can also study specific problems from other people on this topic who have already purchased a gas water heater or instantaneous water heater and thus avoid them. You will find a regularly updated list of such problems and their solutions.
To turn on the Neva 4011 you need to open the gas and water shut-off valves, which are located in front of the device. Set the gas regulator knob (on the front panel) to the “Ignition” position, push it down to the limit. Holding it with one hand, press the piezo ignition button with the other hand, which is located at the bottom of the device. In this case, a spark discharge should appear between the spark plug and the pilot burner, which ignites the gas entering it.
The holding time is about 20 seconds until the pilot burner lights up. The handle can then be lowered. During initial start-up, air should be bled from the gas system. To do this, you need to hold the toggle switch, press and release the piezo ignition button several times.
Next, you need to switch the regulator to the “Turning on the main burner” mode. In this case, only the pilot burner lights up, the main burner lights up after the hot water valve opens. If the tap is open, but the main one is not on, you need to adjust the pressure using the water adjustment, or open it more. You can turn off the column by turning off the water.
The switching on of columns 3212, 3208 also begins by opening the shut-off valves. Next, fix the “Ignition” toggle switch opposite the risk, press the solenoid valve button. While holding the button (about 60 seconds), press the electric ignition button several times (or light it with a match if there is no button, as is the case with some 3208 models) until a flame appears on the pilot burner.
After releasing the solenoid valve button, move the toggle switch all the way to the right, to the “Big Flame” position, the pilot burner is working, the main burner has not yet ignited. When the tap is opened, the main light comes on. To turn off the device, you need to close the tap, turn the knob on the front panel counterclockwise until it stops, and close the gas and water supply valves.

If you want to receive complete information on this problem, as well as find out other important nuances about the gas water heater from your manufacturer, .
But we also have information on this problem and more, which you will not find anywhere, first of all, because it is asked by specific people who could not get more support and advice anywhere (which they themselves tell us). And secondly, their problems are so complex that sometimes our expert Alexander Kholodov takes 10 days or more to deal with people.
And now EVERY question from the user and the answer to it, to avoid financial costs as a result of improper operation or repair of the flow-through heater
And here it doesn’t matter which manufacturer’s device is involved in the issue. The only thing that matters is the unique situation as a result of which this issue arose, because as one good saying goes: “forewarned is forearmed.”
, founded in 1945, produces gas equipment under the famous brand “Neva” (NEVA). The main product of this company is high-quality geysers "Neva Lux" for heating water. There are many models in this production line that differ in power and size. The Neva Lux geyser is most often used in dachas or apartments where a constant supply of hot water is required. Such water heating equipment is made of a metal body, a gas burner, and a heat exchanger made of copper.
The body is covered with enamel. The burner heats a copper heat exchanger through which running water passes. The performance of the column depends on the size of the heat exchanger. "Neva Lux" can be used to heat hard water. All of them are equipped with traction sensors and a safety system that prevents emergency situations. The gas appliance begins instantly heating the water when the tap is turned on and ends when it is closed. The temperature of the water coming from the water heater, thanks to the built-in automation, does not change even with low pressure. Let's look at the most popular models of the Neva Lux line:

Built-in sensors
Potential buyers of water heating equipment are afraid to purchase geysers in the old fashioned way; they are doing it completely in vain. Manufacturers are leaders who supply high quality gas equipment and ensure its complete safety during operation. For this purpose, the design contains a large number of sensors that perform the following functions:
- shutdown when there is no gas supply;
- shutdown when the flame goes out for any reason;
- traction control;
- turning on when opening a hot water tap;
- stopping water heating after reaching the required temperature;
- pressure control in the water supply system.
Electronic controllers protect modern speakers from any excesses, as confirmed by user reviews. Protection systems are triggered by fluctuations in water or gas pressure, an increase in the concentration of combustion products in the ambient air, an excessive increase in water temperature and other non-standard situations.
Maintenance and operation
Regardless of which model you prefer, installation of a wall-mounted boiler is carried out in the shortest possible time without any additional costs.
