Hot water tube for the Neva column 3208. What are the spare parts for Neva gas water heaters
Electronic display
If urban residents do not even think about ways to get to them hot water, then the owners of private houses must independently provide themselves with such an achievement of civilization. At the same time, the Neva gas column often becomes a source of hot water. It is an inexpensive, reliable and compact household appliance for providing residents with hot water. As a rule, it works properly, but breakdowns also occur. Then the owner of the house faces the question of repair and purchase of spare parts for geysers Neva.
Geyser Neva 3208
The Neva gas water heater has been produced in the city of St. Petersburg for a long time, and, perhaps, our mothers and fathers used it. Many modifications have now appeared, but the first model does not give up its positions and remains in demand due to its simplicity and reliability.
Note! Many who use such a device prefer to do simple repairs with their own hands. Therefore, so often consumers are looking for spare parts and accessories for the gas column Neva 3208.
Having mastered the repair of an old model, the consumer can quite successfully carry out simple adjustments to more modern models of gas equipment, while saving considerable sums of money.
The Neva column differs from other models in its clear and understandable control, safety, independence from power supply and economical gas consumption. Ignition in it is carried out at the expense of batteries, which confirms its non-volatility. A guarantee of safety is the fact that the igniter is only switched on when hot water is required. And this leads to gas savings. The gas burner starts working when a hot water tap is opened and immediately stops working as soon as this tap is closed.
What does the gas column Neva 3208 consist of?
The design of the gas column Neva 3208 includes many elements and components, but the most important are:
- heat exchanger;
- main gas burner;
- gas and water unit;
- security group;
- gas and water supply;
- air duct for removal of combustion products;
- auxiliary components - electric or piezo ignition, manual or touch control panel, display, timer and more.
heat exchanger
Heat exchanger Neva Lux
The heat exchanger, of course, is the most important part of the geyser, since it is in it that the water is heated, and it occupies the main volume of the device.
The heat exchanger can be made of steel or copper. The copper aggregate is considered the best, since it is not subject to corrosion and therefore is more durable. In Neva 3208 columns, it is made only from pure copper.
Most often, this column organ needs to be replaced due to the formation of a large layer of scale inside it, which reduces the efficiency of the unit. To prolong the life of the heat exchanger, you should not set the temperature of hot water to the maximum, since only when the water boils a layer of scale forms. If replacement of this unit is required, then such spare parts are always available in the service center.
Gas-burner
The main gas burner is located at the bottom of the column under the heat exchanger circuit and is clearly visible through the viewing window. It is this device that quickly heats the water in the heat exchanger to the desired temperature.
Water and gas units
The water unit, like the gas unit, is responsible for regulating the supply of fuel and water to the main gas burner and a heat exchanger.
In more modern models, such spare parts may not appear, since there these units are combined into a water-gas unit.
Safety
Membrane for column
No less important than the heat exchanger is the safety group.
It consists of:
- thermocouple
- solenoid valve
- overheating sensors
- other devices responsible for the safe operation of the geyser.
In the event of a flame fading on the main burner or igniter, one of these devices will instantly cut off the gas supply. Also, special devices block the access of gas if there is not enough draft in the chimney, or cold water does not enter the heat exchanger.
Eyeliners
To supply gas and water, special supply hoses are needed. Modern products are flexible bellows pipes. Outside, they are braided with a stainless steel metal spiral and equipped with fittings with threaded connection made of brass, fitting and gaskets.
Such eyeliners are highly resistant:
- to thermal expansion;
- reduction in diameter
- transverse compression;
- breaks at the ends.
In addition, the use of flexible hoses reduces the risk of problems with inaccurate installation, and also allows you to quickly and reliably connect the column to the water supply system and the gas main.
air duct
Aluminum air ducts
When gas is burned, various products, soot and soot are invariably released, which must be removed outside the premises. For this, air ducts made of aluminum laminated foil are used. It has several layers and a steel spring to maintain the geometric shape of the corrugated sleeve.
Since the flue gas temperature is at least +110 degrees, the chimney can only be made of metal. Depending on the diameter of the outlet, the diameter of the flexible duct is also selected. The maximum length of such a structure can reach 3 meters.
Auxiliary devices
In the Neva 3208 column, piezo ignition is used as ignition. It works thanks to two batteries that do not contain harmful components such as mercury or cadmium. Therefore, it belongs to environmentally friendly devices.
The information display allows you to see the set water heating temperature. And the timer makes it possible to set the heating mode to the desired parameters.
Various modifications of geysers can have coaxial chimney and a closed combustion chamber equipped with a fan to supply air to the burner.
Functions of additional devices
In addition to the main spare parts that most often fail, the consumer may need others. To know which ones to buy, you need to familiarize yourself with their functions when operating a geyser.
The silicone membrane is highly durable and is designed for water and gas unit. Bending under water pressure, it opens gas access to the main burner. Its rupture leads to the fact that the gas does not ignite. In this case, the membrane must be replaced.
Sometimes a plate with a stem becomes unusable, since it is made of plastic or brass. It happens that the sealing part of the rubber stem is rubbed. They also need to be completely replaced.
The solenoid valve performs a protective function when the gas supply to the main burner suddenly stops, and in other emergency situations.
Safety requirements for the operation of gas water heaters
Main elements
- Installation of the Neva 3208 column, as well as its maintenance with repairs, must be carried out by a specialist who has access to work with gas equipment.
- It is forbidden to throw various things on the column, taking into account the open flame in the burners.
- In the room where the column is located, it is necessary to install ventilation ducts.
- If the column in winter time is located in an unheated room, it is imperative to remove water from the heat exchanger so that the pipes do not break.
- The column can only be operated on the type of gas that is indicated on the front panel of the device.
- In the room where the column is installed, there must be a constant supply of fresh air.
Conclusion
Undoubtedly, the Neva 3208 geyser is a reliable device for heating water. But in order for it to serve longer, it is necessary to fulfill all the requirements set forth in the instructions. And if a breakdown occurs, then you can always purchase the necessary spare parts, because you already know what this or that part is intended for. However, do-it-yourself repair of gas water heaters is not recommended.

In this article, we will consider the most common malfunctions of the Neva 3208 geyser, and describe in detail how to fix them.
Before proceeding with repair work, it is required to close the gas and water valves. Next, you need to remove the casing of the device, this can be done by pulling the gas control knob, which is fixed to the stem with a spring. You will see two screws, the casing is fixed on them, unscrew them.
The column does not light up, reasons:
- There is no traction.
If you have metal-plastic windows installed, the flow of fresh air into the room is very small, and this is the cause of malfunction (read about malfunctions in the operation of the Neva Lux 6011 and 6014 models). In the absence of traction, the device overheats and a protective mechanism is activated. To solve this problem, you need to open the window for ten minutes, then try turning it on again.
Blockage of the ventilation duct with soot or a foreign object that has got there. Checking for blockage is very simple, attach a piece of newsprint to the vent, if it does not fall, the draft is good. In the event of a malfunction, it is required to contact a specialist to clean the ventilation systems.
- Water unit malfunction.
To determine this breakdown, check the flow power cold water and the power of the water leaving the column. If there is less from the column, then the problem is a clogged filter. To clean it, unscrew the nut in the water supply unit, remove and clean the filter and calibration hole.
If the problem persists, check the rubber membrane in the assembly for cleanliness and serviceability. This can be done by opening the water block cover by unscrewing its screws. If it is dirty, clean it, and if signs of deformation are visually visible (in good condition it is flat), a replacement with a new one is required.
- Dirty gas burner. You can only clean the soot that has accumulated inside the burner jets on your own; this cleaning is carried out using a metal brush. Upon completion of work, check the tightness with a soapy solution.
- Perhaps you forgot to open the gas supply valve.
Poor water heating
You can find out complete information on the selection, operation and maintenance of gas water heaters (instantaneous water heaters) of all manufacturers if you go.
In addition to the specific information on the site, you can also study specific problems for other people on this topic who have already bought 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.
The reason may be the formation of scale on the heat exchanger, which does not allow the water to warm up and affects the pressure of the outgoing heated water, and, as a result of all, the gas consumption increases significantly. The cause of scale is hard water in the plumbing and the establishment of too high temperature heating.
To eliminate scale, products sold in the store are used, to save money, you can make them yourself, 200 grams citric acid dilute in 900 ml of boiling water. Cleaning can be done using a special device. Its tubes are connected to the tubes of the heat exchanger, a prepared or purchased reagent flows through them and removes lime.
If it is not possible to purchase this device, you can do everything using a large tank filled with 1/3 water, immersing the heat exchanger in it, after removing water from it. Using a funnel, fill it with a fully prepared product and boil for 30 minutes. Then leave to cool for an hour and a half.
Rinse it under running water and fix it in place. If not all plaque has been removed, repeat the procedure for EVERY user question and answer to avoid costly costs resulting from improper operation or repair of the flow heater. And here it doesn’t matter which manufacturer’s device is involved in the issue. What matters is the unique situation that gave rise to this question, because as one good saying goes: "forewarned is forearmed."
Geysers of domestic production Neva are very popular among Russian consumers. This instantaneous water heater has proven itself on the positive side. This is evidenced by numerous recommendations and reviews of the owners.
In the model range of gas water heaters of this company, the following types of ignition are found.
The most popular gas water heaters with electric ignition. They are easy to use and affordable.
Water heater power
This indicator is determined by the volume of warm water at the outlet. It is logical that the more liters of water the system produces, the more powerful it is.
All gas columns can be divided into:
- small, their power is from 17 to 20 kW;
- medium, from 20 to 26 kW;
- large, from 26 to 28 kW.
Low power equipment is suitable for only one point of water intake. If you plan to install a water heater to supply several systems, then you should choose more powerful options. For example, for 2-3 water intake points according to their technical specifications fitgas column neva lux 5011 or 5014. These are systems with automatic piezo ignition, their power is 24 kW. Reliable equipment that can properly perform the functions assigned to it in conditions of long-term operation.

Combustion chamber type
Modern columns of the Neva company can be either with natural (open) draft or with forced draft. An example open combustion chamber is Neva 4510, the installation instructions for which contain certain requirements for the room in which such equipment is installed:
- an area of at least 8 square meters;
- high-performance ventilation system made of heat-resistant material.
Safety system
Any gas equipment must have a strong security system. The manufacturer of geysers Neva pays special attention to this. All modern models have several degrees of protection and are equipped with special sensors that control the operation of the water heater.
- Safety valve. In the event of an increase in pressure in the system, it stops the supply of gas and water.
- Flame sensor or ionization. Gas control, which stops the gas supply to the burner in the event of the burner going out.
- Thermal relay. Protects the device from overheating. In case of strong heating, it turns off the system.
- Water pressure sensor. It activates and stops the automatic gas supply when the water is turned on.
- Temperature difference control sensor. If necessary, changes the water temperature when connecting and disconnecting several water points. Such a device is installed in geysers of updated models Neva Lux 4514, 4513.
Features of domestic geysers
Geysers of the domestic brand Neva are adapted for Russian water supply systems. According to the manufacturer of OJSC Gazapparat, the water heater continues its operation, even if the pressure is less than 13 mbar. Following the information in the operating instructions, gas water heater The Neva will begin its work at a pressure of 0.2 atmospheres. But you should avoid the constant operation of the equipment under such conditions.
In the Neva 4511 model, the instruction provides for the normal operation of the device even at a pressure of 0.10 bar.
Special mention should be made of maintenance . The service of imported gas water heaters in most cases does not suit consumers. Even in the case of selecting the necessary replacement part, its delivery may take a long time. And not many take on the repair of foreign speakers service centres. A completely different state of affairs for domestic gas instantaneous water heaters. For example, the gas column Neva transit has a removable heat exchanger. The price of the component part is about 4000 rubles. It is this part in such devices that is most vulnerable.
Another advantageous feature of Russian systems is price segment. The cost of such devices, unlike imported models, is cheaper. In addition, such systems are able to work properly for 7-10 years.
