Popular gas equipment - heaters, water heaters, gas stoves and boilers - have been produced in St. Petersburg for more than 50 years. After the creation of the Baltic Gas Company concern, the enterprise became part of it, maintaining its production capacity and specialization. Current name. It is rapidly developing and produces high-tech boilers equipped with modern automation. For example, a popular and sought-after series is Neva Lux gas boilers, which is presented in two categories.
Review of the Neva Lux boiler range
The range of popular gas boilers produced by the Neva company includes two basic series: Lux and Turbo. In this article we will consider the most famous and popular Lux series, which is divided into two categories:
- Single-circuit gas boilers Neva Lux, designed for individual homes. The series is characterized by ease of maintenance, low cost and energy independence.
- Double-circuit wall-mounted gas boilers of the Neva Lux series are equipped with open or closed combustion chambers; the boilers include a bithermic heat exchanger. The chimney can be coaxial or classic. The series is equipped with high-precision automation. It is possible to connect two heating systems to the Neva Lux series boiler, and some models have outlets for organizing heated floors.
Specifications
When installed, the Neva Lux 5514 geyser is located on the wall and has a vertical orientation. The maximum temperature of the supplied water can reach 90 degrees. The diameter of the chimney should be 140 millimeters or more, which will provide sufficiently intense draft. In one minute, the user can get 14 liters of hot water. Before carrying out installation work, you must consider whether the wall can support the weight of the heater, which is equivalent to 12.5 kilograms.
Neva Lux 5514 is equipped with built-in protection against overpressure and overheating, and also has a temperature level regulator. The equipment controls the flow of gas and has a built-in protection system, the latter of which ensures that the device is disconnected from the network if there is no certain level of draft in the chimney. Fuel consumption will be approximately 3 cubic meters per hour, this figure is nominal.
The most popular boilers of the Neva Lux series
Under the Neva brand, modern luxury class gas boilers are produced, which eliminate the shortcomings of previously produced models. The design has been changed, modern automation has been installed, but the price of the products is less than models of Western companies with similar parameters. Other models of domestically produced gas boilers can be found in our article “Russian-made gas boilers: varieties and properties.”
Model Neva luxury 8618
For Neva Lux gas boilers, the price depends on the model. Single-circuit models are cheaper, double-circuit models are more expensive. For example, one of the most popular models in this series, the gas boiler NevaLux 8618, is in demand due to its low price and the following qualities and capabilities:
- small dimensions;
- all models are adapted to Russian conditions;
- the boiler is equipped with a circulation pump manufactured by the Neva company, which facilitates the installation of the boiler into the installed heating system;
- DHW is organized by connecting an indirect heating boiler;
- if necessary, a fan is connected for forced smoke removal;
- connection to a room thermostat is provided.
The popular single-circuit gas boiler Neva Lux 8618 for wall installation is intended only for heating, but if necessary, organizing hot water supply is possible using an indirect heating boiler. The model has the simplest possible design with non-volatile automation. The price of this boiler is the lowest of the entire model range.
Model Neva luxury 8224
The wall-mounted gas boiler Neva Lux 8224 is designed for heating rooms up to 250 m2. The boiler is equipped with a unique water-cooled combustion chamber. High accuracy of temperature setting is ensured by a special microprocessor. In terms of their parameters, Neva boilers are not inferior to foreign models, the only difference that the gas boiler Neva Lux 8224 has is the price, reviews of many owners confirm this.
This model has two heat exchangers. A plate heat exchanger is used for hot water supply, and a copper heat exchanger built into the Neva Lux gas boiler of this series is used for the heating circuit.
The model can use a PC for diagnostics and configuration, as well as remote control.
For the popular gas boiler Neva Lux 8224, reviews found on the Internet fully confirm the excellent consumer qualities of the device. Many reviews emphasize that the Neva Lux 8224 gas boiler has a relatively low price and high performance. This is a wall-mounted double-circuit model, which is designed to heat rooms up to 240 m2. The unit provides hot water supply (DHW).
The company's new product is the Turbo boiler
Neva Turbo boilers are, in fact, a modified version of the already familiar Lux modification, taking into account the shortcomings of previous versions. The models have the following technical characteristics:
Turbo boilers are energy-dependent. The boiler is powered by connecting to a regular 220 V mains voltage. For stable operation, you will need to install a UPS and a generator.
Ease of maintenance and operation
It is enough to connect the installation to the heating and power supply system and start heating your house or apartment. In practice, provided the heating system is already ready, all work takes about 3-4 hours.
After installation, there is no need to worry about the safety of the station. The sequence of operation of the automation completely eliminates the possibility of gas leakage and the creation of an emergency situation, even if an unplanned power outage occurs.
The main differences between Neva boilers
The Turbo modification provides economical gas consumption and, subject to proper operation, fully pays for itself within a few years.
Calculation of power and temperature of a warm water floor
Russian wall-mounted gas double-circuit boilers Neva provide consumers with maximum comfort when switching to autonomous heating and hot water supply. This equipment is intended for use in multi-apartment residential premises and country houses. For the production of boilers, modern materials are used, as well as high-quality components from the best European suppliers. The company's designers conduct a constant scientific research, testing prototypes of new models on an experimental one before launching into mass production.
Thanks to this, it is possible to correct all the shortcomings, improve the manufacturability of production and, which is important for gas equipment, increase the degree of its reliability. The domestic manufacturer BaltGaz has implemented two design options in Neva Lux gas double-circuit boilers. Thus, in the boilers of the 72 series, as well as in the BaltGaz 18 DBF boiler, a single bithermal heat exchanger is installed to work with heating and hot water circuits
This decision made it possible to reduce production costs, which had a positive effect on the pricing of these products. In addition, the products of the 72 series provide precise temperature control with a tolerance of 1 0 C. The models of the 82 and 86 series use a traditional layout with two heat exchangers - copper for the heating circuit and plate for the hot water supply circuit. The entire line of double-circuit boilers, with the exception of the Nevalux-8624 model, is equipped with a closed combustion chamber. In addition to the above, Nevalux gas double-circuit boilers are distinguished by thermal performance and minor design details:
- Nevalux-7211 - thermal power 11 kW, bithermal heat exchanger, maximum heating area - 110 m2
- Nevalux-7218 - thermal power 18 kW, bithermal heat exchanger, maximum heating area - 180 m2
- Nevalux-7224 - thermal power 24 kW, bithermic heat exchanger, maximum heating area - 240 m2
- BaltGaz 18 DBF - thermal power 18 kW, bithermal heat exchanger, maximum heating area - 180 m2
- Nevalux-8624 - thermal power 24 kW, copper heat exchanger (heating) and plate heat exchanger (DHW), maximum heating area - 240 m2
- Nevalux-8224 - thermal power 24 kW, copper heat exchanger (heating) and plate heat exchanger (DHW), maximum heating area - 240 m2
- Nevalux-8230 - thermal power 30 kW, copper heat exchanger (heating) and plate heat exchanger (DHW), maximum heating area - 300 m2
wall-mounted boilers
Wall-mounted gas boilers are in great demand among consumers who have a house or small cottage. This is due to the advantages of this type of equipment. Thus, the wall-mounted boiler has small external dimensions, due to which the equipment can be installed indoors with minimal loss of space. The equipment does not make noise during operation and is capable of stably performing assigned tasks, regardless of operating conditions. Many users choose the Neva Lux double-circuit gas wall-mounted boiler for installation in the heating systems of their homes, the advantages and main technical characteristics of which will be discussed below.
Structural components
From a technical point of view, the Neva wall-mounted gas boiler is impeccable. It implements all the technical advances in heating engineering, as well as developments in the field of electronic control of heating circuits.
Structurally, the Neva double-circuit gas boiler consists of the following interconnected systems:
- a control system consisting of an electronic unit that controls the operation of the boiler and ensures safety, and an electrical harness that connects sensors, an electronic board and other devices into a single system;
- hydraulic system, including a pump for forced circulation, an automatic valve for removing air, a heat exchanger for heating the coolant, a secondary heat exchanger for the hot water system;

Advertising on the Internet and on television encourages you to buy a Neva Lux double-circuit wall-mounted gas boiler as the most economical, cheapest, most convenient, etc. Can you trust this advertising and reviews on the web pages of online stores?
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.
How to buy a gas boiler and not make a mistake?
A buyer, choosing, for example, a wall-mounted gas boiler Neva Lux 8224 reviews for which may be false and written to order, must understand that they cannot be relied on. After all, it often happens that the design is ideal, the equipment is the most modern, but poor-quality assembly worsens all the advantages. For example, in 2014, reviews characterized the wall-mounted gas boiler Neva Lux 8224 as a naturally raw product, which is called “finish it with a file.”
This review appeared due to poor quality assembly, as well as due to unstable operation of the boiler due to a defect in the coaxial chimney, which was not specified in the instructions. Of course, the Neva company has now taken certain measures and eliminated shortcomings in the assembly of the product. There are practically no complaints about the Lux 8618 model and you can buy a single-circuit wall-mounted gas boiler Neva Lux, with delivery to any region, in specialized stores.
Prices for mounted gas boilers depend on their power, type, configuration and demand for the device. For example, the Neva Lux gas double-circuit wall-mounted boiler offered by many online stores, the price of which with a power of 24 kW, but with different configurations, ranges from 31,800 to 35,600 rubles.
The most expensive boiler, Nevalux 8224, is equipped with a built-in storage boiler. When choosing a boiler for heating, if you are satisfied with the gas boiler Neva Lux 8224 price, it is best to get reviews from real owners or gas equipment specialists.
How to clean the Neva column at home
In order for the Neva boiler to continue to function properly, the heat exchanger must be flushed every 2-3 years, removing accumulated scale and soot. You can clean the Neva gas water heater at home even if the water quality is poor. Maintenance is carried out in several stages:
- Remove the radiator - to pull out the heat exchanger of the Neva column, unscrew the casing, disconnect the water and gas. Dismantle the smoke exhaust unit. They take out the radiator.
The heat exchanger is washed and cleaned - soot is removed from the plates using a stiff brush and soap solution. To remove scale, the internal cavity of the coil is washed with a special “chemistry” or citric acid.
In case of serious contamination, the column should be serviced at a specialized service center. Washing is carried out using pumping equipment.
After reading comments from real users about the features of using gas water heaters from BaltGaz, we can highlight several pros and cons of boilers:Advantages:
- Warranty repairs are provided on a full scale; there are service centers in every region of the Russian Federation, within transport accessibility.
The cost of geysers Neva and Neva Lux is approximately at the level of Chinese products, but the build quality is significantly higher.
Ease of repair - spare parts for the Neva dispenser are cheap, the market has all the necessary components separately and repair kits.
Flaws:
- There are minor flaws, especially obvious in models with modulating burners.
Low quality heat exchanger, sensitive to lack of maintenance.
The water regulator often fails.
Below are several reviews about the use of Neva and Neva Lux speakers:
Review author: Burak Yuri
What attracted me to the column was its appearance and functionality. During operation, I noticed the following disadvantages: after a few years, the temperature sensor failed, and the heat exchanger leaked almost immediately. Fortunately, any part can be found on the market without any problems.
Review author: Popov Alexander
I chose the automatic model 6014. The main drawback is failures in flame modulation. Water heating occurs intermittently. First, the temperature rises to 55-60°. Only after a few minutes the heating gradually levels out and decreases to 40°C
Review author: Sergey Uryupin
The problem with excessive heating is solved. To do this, you need to adjust the column correctly. There is no need to skimp on calling specialists and try to install and connect the water heater yourself.
Malfunctions of the gas boiler Neva Lux
The simplest single-circuit and non-volatile model Neva Lux 8618. It completely lacks electronics. A simple Neva gas boiler is very reliable.
The most common faults characteristic of this boiler are the following:
- very low level of gas pressure in the line;
- low pressure due to the presence of air in the circuit;
- burner flame goes out;
- mechanical damage to the boiler or heating circuit.
The presence of a control unit with a microprocessor in the Neva Lux 8224 model allows for self-diagnosis of faults that arise during the operation of the gas boiler. The electronics installed on the Neva Lux double-circuit gas boiler displays faults on the display in the form of an error code.

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.
