Gas water heater neva 4511. Heating systems for country and country houses

In our recent past, having a gas column or water heater in the house was a sign of wealth, almost like having a car. This meant that there was always hot water in the house! Now, of course, it is difficult to surprise anyone with hot water, but miracle machines, gas water heaters, do not lose their relevance.

Hot, clean, inexpensive water at any time - these are the main advantages of a gas water heater. The NEVA-4511 P gas instantaneous water heater of a well-known Russian manufacturer was designed by engineers in St. Petersburg and manufactured at the Armavir Gas Equipment Plant.

Geyser Neva 4511 R is one of the most famous economy class models on the St. Petersburg market. The ignition of this model is from a piezo element, hence the letter P in the model name.

Neva 4511 R is very compact (only 29 cm wide), light, so finding a suitable place for its installation is not difficult even in a small apartment. Strict elegant style, colors (calm white or metallic gray) are very close in spirit to the residents of the Northern Capital and other regions of Russia.

Many residents of multi-storey buildings experience problems due to insufficient water pressure (pressure) in the apartment. Basically, this happens when the water supply system is worn out or when your house is located away from the boiler room, on the upper floors.

The gas column Neva 4511 R is specially designed for Russian operating conditions, the column can operate even at reduced water pressure (from 0.15 atm). In addition, it is equipped with a safety system with an ionization flame control sensor. If for some reason the flame goes out, the system will immediately shut off the gas supply. Changing the flame height at different water flow rates is carried out manually, using the water temperature control knob. This model is distinguished by the presence of a durable copper heat exchanger, it is slightly larger than that of the Neva 4510 M model, without tin and lead alloys, manufactured using innovative soldering technology in a protective environment.

With all the advantages of the gas column Neva 4511 R, it should be noted its low power - 21 kW, with a capacity of 11 liters / min. It lacks the modulation of the burner flame, which is found in more advanced gas water heaters. Therefore, it is most effective to use this column if you plan to use one draw-off point at the same time. If you need hot water to be in the bathroom and in the kitchen at the same time, then you need a higher power column, such as Neva 4513 M and Neva 5514. The Neva 4511 R gas water heater is one of the simplest and most inexpensive gas water heaters from the Neva series.

It is worth noting an important detail: most of the components and spare parts for the Neva speakers are produced at the same factory and therefore are always in stock, they do not have to wait for weeks and overpay several times, as for imported counterparts. Here you can always find a full range of accessories and spare parts for gas water heaters Neva at affordable prices.

Gas equipment is technically complex, so the installation and connection of any geyser should be carried out only by licensed specialists who are professionally engaged in gas work. When buying a gas column Neva 4511 R, our specialists will be able to install it quickly, efficiently and for a reasonable price.

Water heaters are becoming more and more popular in our everyday life. So that circumstances do not catch us at the wrong moment, we strive to predict all situations.

For urban residents, hot water shutdowns have become habitual. In the private sector, the problem of water heating has never disappeared. It is for such cases that gas columns are suitable.

Types of devices

The geyser is a water heater. Gas is the main source of energy.

The main criterion for choosing a geyser is the characteristics of the apparatus, its quality and price.

Conventionally, according to the technical characteristics, the columns can be divided into types:

• by type of ignition;
• by type of chimney;
• by power (on which the volume of heated water depends);
• for security;
• to size;
• for additional features.

As for the quality of the product, the popularity and fame of the brand can be decisive. In the domestic market, NEVA is a quality manufacturer. This is confirmed by many product reviews. The quality of components and assembly is a guarantee of the reliability of the device.

Column ignition

The ignition of the column means the ignition of gas, namely the method, in gas columns it happens:

• ignition manually;
• piezo ignition;
• electronic;
• microturbine.

Manual ignition is a rarity for modern speakers. In older models, matches were needed to set fire to the gas. These models are rare today.

Piezo ignition. By analogy with piezo electric stoves, to set fire to the gas, you need to press the button on the column panel. This method is still used in modern models.

Electronic. The most convenient and popular way. Reliability and efficiency in gas consumption make such models a little more expensive. By analogy with a car, a spark is created by a small battery, batteries are more often used. The column NEVA 4511 belongs to this model range.

As for microturbines, the current in them is generated by a hydrodynamic generator controlled by a water flow. The cost of such copies is much higher.

Columns with electric ignition are easy to operate. The gas is ignited automatically when the water tap is opened, thus you can save gas consumption.

Type of removal of combustion products

Atmospheric speakers are available for sale. They discharge combustion waste directly into the chimneys.

The branded range of NEVA columns is represented by HSV models from series 10 to 14, in various modifications.

Turbine columns are not connected to the chimney, they take oxygen for combustion from the outside and throw the combustion products out there. They are designed to be installed on any floor in a building in homes without chimneys. The higher price is justified by the convenience of their use, since it is much more expensive to build chimneys.

Power

The power of an instantaneous water heater is determined by the volume of water that it can heat. To heat a large amount of water, you will need a powerful unit.

According to their power, the speakers can be divided into:

• power from 17 - 20 kW (small columns);
• from 20 - 26 kW (medium);
• from 26 - 28 (high power).

Column NEVA model 4511 consumes 21 kW, but at the same time produces up to 11 liters of hot water per minute. For an approximate definition of liters per minute, take a look at this table:

The column NEVA 4511 is suitable for two points of water intake. If you need to use more points, it is better to take a column with more power. The NEVA 4511 column is the most compact of the entire series and is suitable for small spaces. More powerful speakers NEVA from the Lux series.

Safety in use

The geyser is a device of increased danger.

To simplify the use and prevent various accidents, the columns are equipped with additional sensors. Among which:

1. Ionization sensor. If the fire goes out, the sensor shuts off the gas supply.
2. Additional thermocouples. They work in case of failure of the ionization sensor.
3. Heating sensor. Monitors the temperature of the flow heater, i.e. regulates the temperature of the entire device, as well as the heating elements.
4. Water pressure sensor, the main task of which is to turn on or off the gas supply automatically when drawing water.
5. Temperature difference control sensor. The device for raising and lowering the water temperature, in case someone additionally opened the water, is implemented in the newer Neva Lux models, model 4514, 4513.
6. Gas and water pressure sensor. Control the flow of water or gas into the column. If the tap with water is opened, when it is turned off, the column will not automatically supply gas.
7. Safety valves. Shut off the water or gas supply in case of increased pressure in the system.

Features of domestic systems

This means that when the gas pressure drops below 13 mbar, the column continues to work.

At the same time, automation does not allow turning on the device at low pressure. Gas supply in our territorial latitudes is a secondary problem. The main task is to control the water pressure.

An important advantage of the columns Neva and Neva Lux can be called a replaceable heat exchanger. Instead of buying a new column, it is enough to purchase a component part. It costs from 3500 to 4500 thousand rubles, depending on its type. In new models, a copper heat exchanger is installed, such a material is resistant to corrosion, but salt and scale deposits remain a problem.

Ignition methods

In the model range of gas water heaters of this company, the following types of ignition are found.

1. Pilot burner(for example, in the Neva 3208 model). There are some features of its use, indicated in the manual. So, before the first start, the igniter must be set on fire manually. To do this, two buttons are simultaneously pressed: gas and piezoelectric device. At this moment, gas and a spark are supplied to the igniter, as a result, a flame will be ignited, which will burn constantly. After the user opens the tap, the main burner will light up from the igniter, and after a short period of time warm water will flow.
2. Electric ignition. The principle of operation is the same as in piezo ignition, but instead of an igniter, an electric source is used, which is powered by batteries. This method is economical (in terms of gas consumption) - this is a modern version of gas water heaters. Models with electronic automatic ignition include the Neva 4511 geyser, as well as 5011 and 5014 models;
3. Hydro turbine ignition. Its action is based on the pressure of the water flow. The main advantage of such geysers is automatic and safe operation, not dependent on batteries. But such models cost much more.

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 its technical characteristics, it is suitablegas water heater 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 reliable 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.

1. Safety valve. In the event of an increase in pressure in the system, it stops the supply of gas and water.
2. Flame sensor or ionization. Gas control, which stops the gas supply to the burner in the event of the burner going out.
3. Thermal relay. Protects the device from overheating. In case of strong heating, it turns off the system.
4. Water pressure sensor. It activates and stops the automatic gas supply when the water is turned on.
5. 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 data in the operating instructions, the Neva gas water heater will start its operation 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 service centers undertake the repair of foreign speakers. 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.

Buyers say:

Geyser Neva 4511 gets good reviews: Most buyers focus on the affordable price and fairly good quality of the product.

“The parents, having decided to change the column at home, consulted the seller and purchased the domestic Neva 4511. Since they are pensioners, the low cost of the water heater suited them perfectly. Using, they are very happy, the device works without problems, it does not take up much space, decent power. Recommend to all my family and friends."

Sveta Seliverstova, Moscow.

“Having tested this unit, I can highlight the advantages: automation, a copper radiator. The disadvantages include: often you need to change the batteries, every 2 - 3 months, it is better to put alkaline ones (they are more expensive, but they will last longer); wires stick out from under the bottom; components made in China. If it turns off after heating, then it is necessary to replace the draft sensor. I turned it 180 0 and set it up. After that, the warm air from the burner does not get on it, everything is fine.

Igor, Voronezh.

“I like the model 4511 that it has a temperature indicator, temperature and pressure adjustments, compact dimensions, and a low price. I didn’t like the work, which sometimes makes noise, the throughput is low, the water temperature depends on the pressure. ”

Mikhail Granyuk, Korolev.

“The sizes are small, it works quietly, there is no wick. Made in Russia, and the parts are most likely Chinese. Sometimes there are pops when turned on, for 5 months of use it has become a little louder to work. But when compared with what was before, it works almost silently. When the second tap is opened, the pressure drops very much.

Marina Azhar, Rostov-on-Don.

“I installed it myself for a shower in the country. Be sure to check all details before installation. Most nuts are simply slid onto connectors. We've been using it for over a year. At first it worked well, though there was uneven heating. With a weak gas flow, it warms up for a long time. If the gas is turned on strongly, it quickly heats up and turns off due to overheating. Moreover, a strong flow of water is needed, with a weak one it does not turn on. After a month and a half of work, the solenoid valve broke. Changed. After wintering in a dry room, in the new season it began to work normally. After a couple of weeks, pops began to be heard. Changed the batteries. And again, after a couple of weeks, the solenoid valve broke down.

Andrey Shishparenok, Moscow.

“I chose a column for a long time, I stopped at Neva 4511. I have been using it for more than two years. There are no complaints. The batteries are still the same. Some begin to complain about cotton. I don't care, I can't hear it at all in the bathroom. Disadvantage: the pressure of water affects, the less, the hotter. I guess it's normal."

Valery, St. Petersburg.

• Efficiency - 87%.

Gas water heater Neva 4511 is designed for instant heating of water in apartments and private houses. It is mounted vertically and connected to a natural draft chimney to remove combustion products. The device is designed for 1-2 points of water intake. Natural or liquefied gas can be used as fuel.

The water heater Neva 4511 is rectangular in shape, has an ergonomic classic design (lined with a white or silver panel) and compact dimensions: height - 56.5, depth - 22.1, width - 29 cm, weight - 10 kg. In front of the shoe there are knobs for regulating the flow of water and gas, as well as a digital display showing the temperature of the liquid at the outlet.

The two-tier heat exchanger of the Neva 4511 column is made of copper without impurities of tin and lead. The diameter of its pipes is increased, which protects against the accumulation of scale. The unique burner is made of stainless steel, which has a positive effect on its service life.

The operation of the column is started by opening a tap with hot water. At the same time, the automatic electronic ignition system is activated, emitting spark discharges and powered by batteries.

The safety system of the water heater deserves special attention. The device turns off in the absence of gas, water supply, attenuation of the pilot burner, heating of the liquid above 90 ° and violation of draft in the chimney. There is no doubt about the availability of such a device as the Neva-4511 gas water heater, the price varies from 8400 to 12000 rubles. in different stores.

Note: The Neva 4511 water heater can operate even with reduced water pressure in the system (from 0.15 atm). Manufacturer's warranty - 2 years. The approximate service life of the column is 12 years.

Advantages and disadvantages of the column

Let's find out what advantages the Neva-4511 gas water heater has based on technical specifications and reviews. Main advantages:

• compact dimensions;
• classic column design;
• low price;
• ease of use;
• minimum noise level;
• convenient system for turning on / off the column;
• presence of the indicator of inclusion and temperature;
• security system that meets world requirements;
• the ability to adjust the water flow and temperature level;
• availability of repair and maintenance of the column - a large number of service centers, inexpensive spare parts.

When considering such a heater model as the Neva-4511 geyser, the reviews show that the device has certain disadvantages, including:

• The efficiency is lower than that of imported analogues, that is, the device consumes more fuel to heat the same amount of water;
• lack of control of the outlet water temperature - you can only adjust the difference in temperatures by which the water is heated, if the degree of water at the inlet suddenly increases, too hot liquid will flow from the tap;
• the low bandwidth of the column, in fact, it is enough for one point - for example, if one of the family members takes a shower, then you cannot open the faucet in the kitchen, otherwise it will burn;
• the heat exchanger quickly “clogs” if tap water is of poor quality;
• the device can only be installed on a dry wall with good thermal insulation;
• Batteries need to be changed periodically.

For some users, the Neva 4511 column lasts a long time, for others it breaks quickly. The quality of the assembly of the device and compliance with the rules of operation affect the term.

Possible column malfunctions and their elimination

If the Neva-4511 geyser breaks down, is do-it-yourself repair possible or not? Minor problems are easy to fix on your own. Let's look at the reasons for some of them.

The water heater switches off after a short period of operation:

1. Low traction. It is necessary to clean the chimney and check the connection of the exhaust pipe, if necessary, seal it.
2. The water leaving the dispenser is too hot (over 90 °C). Close the tap, wait 1-2 minutes and adjust the inlet water temperature (increase water flow, decrease gas flow).
3. There is carbon deposits on the flame sensor. It needs to be cleaned.

Opening the tap does not start the column, there is no spark charge:

1. Batteries don't work. They need to be replaced or installed correctly.
2. The taps are partially open. It is necessary to fully open the taps at the inlet and outlet of water.
3. Insufficient amount of water. Fluid flow should be adjusted.
4. Weak water pressure in the system. You need to contact the utility.
5. Filters clogged and/or scale has accumulated in the column heat exchanger. Needs to be cleaned.

Opening the tap does not start the column, but there is a spark charge:

1. The gas supply valve is closed. It needs to be opened.
2. There is air in communications. The problem often occurs when the column is first started and after a long period of inactivity. Open the tap, wait 7 seconds, close and open again. Manipulations must be repeated several times.
3. The spark does not enter the gas jet. It is required to adjust the distance between the electrode of the candle and the burner.

The nuances of adjusting a device such as the Neva-4511 gas water heater and troubleshooting it are described in detail in the instructions. It is important to read it carefully before using it. In difficult situations, it is better to contact specialists.

The Neva 4511 column is an affordable water heater manufactured in Russia. The device is characterized by compact size, automatic switching mechanism, low power consumption and multi-level security system. The disadvantages include the small capacity of the water heater, but for a family of 2-3 people it is enough.

Since the Neva gas water heater of the 4511 series is one of the most common models, the topic of its maintenance and repair is of interest to many users who are used to doing such work with their own hands. Indeed, these open-chamber instantaneous water heaters can often be brought back to life without resorting to service personnel. Let's look at what malfunctions occur during the operation of these units, as well as ways to eliminate them.

The device and principle of operation of the model Neva 4511

It is impossible to repair a household appliance on your own without knowing how it functions and what it consists of. Unlike old-style water heaters, this series of geysers is equipped with a controller and electric ignition, which made it possible to remove the constantly burning igniter. The rest of the design remained quite simple and maintainable. It consists of the following main elements:

1. Housing with hinges for wall mounting.
2. Diffuser - a collection of combustion products with a pipe for the chimney.
3. Copper heat exchanger.
4. Gas burner device.
5. Water node.
6. Membrane actuating element (the so-called frog).
7. Gas valve with an electromagnet connected by a common stem to the water unit.
8. Controller.
9. Microswitch for power supply to the electronic unit.
10. Water supply pipes.
11. Ignition electrode.
12. Flame sensor (ionization).
13. Additional electrode for ignition of the burner.
14. A tap is a flow regulator.
15. Adjustment of intensity of burning and temperature of heating.
16. Connecting the draft sensor installed inside the diffuser.
17. Compartment for batteries (batteries).

The diagram above shows the device of the Neva gas column with the numerical designations of the parts corresponding to the list.

Automatic switching on and heating is controlled by a water unit together with a controller, and a solenoid valve connected to a draft sensor is responsible for the safe supply of gas. The algorithm of operation of the water heater looks like this:

1. After opening the hot water tap at the inlet of the "frog", pressure arises that acts on the rubber membrane of the assembly. It moves the stem, which opens the gas valve and closes the contacts of the microswitch.
2. When the electrical circuit is closed, battery power is supplied to the controller. It gives 2 commands at the same time: open the solenoid valve for the passage of gas and create a spark on the ignition electrodes. As a result, the burner is ignited.
3. The flame sensor detects the appearance of fire and transmits an impulse to the electronic unit, which interrupts the sparking. The heater goes into operation.
4. When the valve on the mixer is closed, the pressure in the network disappears and the spring throws the “frog” membrane back, simultaneously closing the mechanical gas valve. The limit microswitch is activated and the controller loses power, and with it the electromagnet. The fuel supply stops and the burner goes out.

Fundamental moment. The solenoid valve is connected in one circuit with the draft sensor (pos. 16 of the diagram). If for various reasons the draft disappears or weakens in the chimney, the sensor will heat up and open the circuit, de-energizing the electromagnet. The latter will return to the closed position and shut off the gas supply to the burner.

To exclude possible overheating of water in the heat exchanger, the manufacturer implemented a simple technical solution: a temperature sensor connected to the controller is built into the pipeline. If the flow heats up to a critical level (about 90 °C), the gas supply will automatically stop and the burner will go out. More clearly, the structure and principle of operation of the Neva 4511 column is shown in the video:

Water heater repair

In order to fix the malfunction of the Neva gas column with your own hands, you need to correctly diagnose it. Over the years of operation of the water heater, one part of the parts wears out and needs to be replaced, the other part needs periodic maintenance. In this case, various problems occur, characterized by certain symptoms. We propose to divide all emerging problems into groups according to the following criteria:

• the burner does not light up when the DHW tap is opened;
• after working for 5-10 seconds, the unit turns off;
• the flow heater starts and functions properly, but does not heat the water well;
• other problems.

Advice. Most often, in geysers, the rubber membrane of the water unit fails - it stretches, cracks or breaks. This is a consumable spare part that you should always have in stock. A sample of the part is shown in the photo.

What to do if the column does not ignite

When the water heater does not react in any way to turning on hot water, you need to perform the simplest action - check the condition of the batteries and battery compartment contacts (they may oxidize). Clean them with sandpaper, install a new set of batteries, and then retry ignition.

An important point. The glowing display of a household appliance does not at all indicate the full charge of the batteries, since it does not consume much energy. If the batteries are "sat down", then the voltage for the operation of the electromagnet and sparking may not be enough. According to the characteristics published on the official website of the manufacturer, a set of elements is enough for about 250 hours of operation.

Battery compartment location - bottom view of the device

Is the power supply okay? Then continue the diagnosis of the geyser according to the following algorithm:

1. Make sure that there is enough pressure in the piping to turn on the machine. Perhaps someone accidentally closed the shut-off valve or the control valve on the heater itself (on the right).
2. If there is a mesh filter on the incoming water supply, check its condition and clean if necessary.
3. Remove the front panel of the device and open the DHW valve, observing the stem. If he did not move under normal water pressure, the reason lies in the "frog" membrane.
4. The stem has moved, released the switch button, but nothing happens? There is a problem with the electrical circuits. You need to check the microswitch and ring other wires that feed the controller and solenoid valve.

Advice. When repairing the Neva gas column, accompanied by disassembling the unit, just in case, shut off the gas line.

To dismantle the front cover, remove the plastic handles from the control valves and disconnect the display connector. At the back, the panel rests on 2 self-tapping screws located at the bottom of the device. Turn them out and remove the casing by pulling it towards you and pulling it up.

To check the limit switch, you must disconnect the connector and ring it with a multimeter or a lamp tester. When the button is pressed, the circuit should be open. As for the wiring, it rarely fails, unless you catch your eye a fallen wire, which is easily eliminated.

To replace the membrane in the Neva 4511 column, remove and disassemble the water unit together with the gas unit, following the instructions:

1. Close the supply of cold water and gas, unscrew both supply pipes with an open-end wrench. Also disconnect the copper tube leading to the heat exchanger.
2. Disconnect the controller and microswitch connectors.
3. The entire water-gas block is attached with 2 screws to the burner flange. Unscrew them with a Phillips screwdriver and remove the assembly.
4. Disassemble the "frog" and replace the membrane, and with it the small o-ring shown in the photo.

Note. Replacement can be done without dismantling the whole unit, but it is extremely inconvenient to perform the operation in this position. The described disassembly technology is also suitable for other models of gas water heaters - Neva Lux 4510, 5611 and so on.

How the membrane of the instantaneous water heater changes, see the next video:

There is a spark - no ignition

When sparking is noticeable on the glow plug, but the burner is inactive, the following points should be checked:

• whether the spark electrode has moved relative to the nozzle;
• whether the draft or overheating sensor, which opens the solenoid valve circuit, has failed;
• whether a high-voltage wire breaks into the case;
• whether the spark has weakened due to a clogged spark plug or exhausted batteries.

The electrode should be directly above the nozzle of one of the burner sections at a distance of no more than 5 mm from it. Violation of the position of the candle is corrected by simple bending. Sometimes it is enough to clean the end of the electrode from soot so that the power of the spark increases.

The operation of the draft and overheating sensors is checked by direct closure of their contacts. Place the jumpers on each device in turn, including the water on the faucet. If a flame appears, replace the faulty sensor.

After starting, the burner goes out

If the flame in the column regularly lights up with the appearance of a drawdown, and goes out after 5-10 seconds, then the reasons may be as follows:

• the ionization sensor does not work (does not detect fuel ignition);
• there is no draft in the chimney, which causes the corresponding sensor to overheat and open the electrical circuit;
• the maximum heating is set at a low water flow, which is why its temperature quickly reaches 90 ° C and the overheating sensor is triggered.

The last 2 malfunctions do not depend on the water heater and are eliminated by the user on an individual basis. Sometimes the damping effect is created by a membrane that is too stretched: at the first moment after water is supplied, it moves the stem, and when the pressure in the pipe is normalized, it releases again.

The flame sensor fails for three reasons:

1. The electrode is covered with a thick layer of soot and needs to be cleaned.
2. The “nose” of the device is bent down from prolonged exposure to temperature and needs to be slightly bent up, as shown in the video.
3. The device is out of order and needs to be replaced.

The reverse situation also happens: the DHW tap is closed, and the burner continues to work. There is a stem jamming here, which is eliminated by disassembling and cleaning the water-gas block.

How to eliminate weak heat

There are two reasons for this phenomenon: clogging of the burner nozzles and deposits in the heat exchanger tubes. In the first case, a change in the blue color of the flame to yellow or reddish is noticeable, the gas burner begins to smoke. To eliminate it, it is advisable to call the master of the gas service, but if necessary, you can handle it yourself:

1. Shut off the gas supply.
2. Dismantle the burner by unscrewing the clamping nut on the gas pipeline and 4 screws shown below (not photo).
3. Blow out the assembly in an accessible way from dust, and then wash with a mild soapy solution.
4. Dry the device and assemble the column in reverse order.

If the burner is working properly, but the water does not heat up, then you need to flush the heat exchanger. The manufacturer provides for a simplified dismantling of the element: drain the water from the column, unscrew the two connecting nuts on the tubes (shown in the photo with green arrows) and 2 mounting screws on top. After that, immerse the heat exchanger in a bucket with a solution of citric acid (100 grams per 1 liter of water) and wait until it eats away the scale. After thoroughly rinsing and drying, reinstall the element.

Advice. When reassembling the heat exchanger, it is advisable to change the rubber gaskets inside the union nuts.

Conclusion

It cannot be said that it is unrealistic or unacceptable to repair the Neva gas column yourself. You can really deal with the common malfunctions described above on your own, and without any special tools. It should be remembered that the water heater is a gas-using equipment that requires a careful and thorough approach.

Among the huge variety of water heating equipment, it can be quite difficult for an ordinary consumer to choose the right model for the home. Knowledge of the basic principle of operation of devices, technical characteristics and design features will help to deal with this difficult issue. Together with the experts of the online magazine, the site will consider what the Neva gas water heater is, the criteria for choosing water heaters and a detailed overview of the model range.

Read in the article:

When the Neva gas column is used, its purpose

Despite the fact that many modern homes have centralized hot water supply, domestic gas water heaters have not lost their relevance. Such equipment provides comfortable living conditions for many inhabitants. Flow heaters allow you to use hot water for domestic needs at any time convenient for consumers and not depend on the work of municipal utilities.

Among the huge number of geysers of imported and domestic production on the market, it is worth highlighting the devices of the Neva brand. The products are manufactured at the Russian enterprise "Gazapparat", equipped with modern automation and have a high build quality. All models are designed taking into account the peculiarities of operation of domestic gas and water mains, which ensures uninterrupted operation of the equipment.

The general principle of operation of gas water heaters Neva and their types

Let's consider the principle of operation of the Neva household water-heating gas equipment and its varieties. The columns differ from each other in terms of the type of ignition of the incoming fuel, the design features of the chimney, power, weight and size indicators, the level of safety and the presence of additional functions.

The principle of operation of the Neva brand columns is as follows: after opening the valve, under pressure, water enters the cavity of the water-gas unit (12). It has a membrane that acts through the stem on the valve. After opening it, the gas enters the main burner (10).

Thanks to the electrode, gas is ignited using a pilot burner (3). In turn, water rushes into the heat exchanger pipeline (2), where it is heated to a certain temperature and flows to all intake points in the dwelling. The principle of the Neva gas water heaters is almost the same. All models have a long warranty period (for example, for the Neva 4511 brand, it is 12 years).

Geysers Neva: main technical characteristics

Performance

One of the main parameters of the Neva gas instantaneous water heater, which you should pay attention to when choosing a model, is its performance. The power of the column is determined by the volume of incoming liquid, which the unit is able to heat for a certain period of time.

Neva speakers are low-power - 17-20 kW, medium performance - up to 26 kW and high power - up to 28 kW. For a small family, a small unit of 17-18 kW is quite suitable. If you have to consume hot water in large volumes, you should choose models with a capacity of 26-28 kW.

Table 1. Relationship between column power and liquid flow

Max pressure

When choosing Neva water heaters, it is extremely important to take into account such a parameter as an indicator of water pressure, and its minimum and maximum values ​​\u200b\u200bare to be taken into account. In the first case, it must be at least 0.19 atmospheres, otherwise the column simply will not turn on. This is especially true for houses of old construction, in which pipelines of highways are very worn out.

The maximum pressure value indicates the degree of load that the column can withstand. For gas water heaters, it ranges from 9.9 to 11.8 atmospheres. It is known that water hammers of a certain force are often formed in water mains, which can completely destroy the design of the heat exchanger.

Ignition type

In modern models of columns for domestic use, various types of burner ignition are used. A little earlier, only the manual type was used, in which the gas was ignited using an open flame.

Table 2. Types of ignition of domestic instantaneous water heaters

Ignition type	Image	Description
Piezo ignition		A piezoelectric element can be used to ignite the gas in the columns. The ignition is carried out by pressing a button installed on the equipment panel.
Electronic		The column has an autonomous power source (batteries) that feeds the electronic ignition unit.
microturbine		Microturbine ignition is carried out by a hydrodynamic type generator. The water flow acts as a mover, rotates the turbine, which generates current. The device is characterized by high reliability and long service life.

Power modulation

Among the additional functionality that some Neva speaker models are equipped with is power modulation. Thanks to a special device, users can adjust the flame. The degree of heating of the heat exchanger depends on its intensity. Adjustment is carried out by reducing or increasing the water pressure.

Using modulation, you can use water of a certain temperature, and the column will work normally, regardless of the number of storeys and pressure in the house's carrier line. As practice shows, this function contributes to economical gas consumption. It also ensures the safety of users by protecting them from thermal burns.

Type of heat exchangers

Before you buy a Neva gas water heater, you should find out which heat exchanger is installed on it. This structural element is made of steel, as well as copper of simple and high purity. In the first case, the equipment is inexpensive, has a large weight, and is characterized by high reliability in operation.

Heat exchangers made of simple copper are characterized by uneven heating. This is due to the presence of various impurities in the metal. For this reason, pipes fail quickly enough, since cracks form on their surface.

The most reliable are columns with highly purified copper heat exchangers. The heat transfer of such a design is significantly higher and, accordingly, the efficiency indicator. The cost of columns with a copper heat exchanger of this type is more than analogues, however, they last much longer without the need for repair work.

Type of removal of combustion products

To date, the most widely used columns with an atmospheric type of output of combustion products - through the chimney channels. After installing the water heater, an air duct is connected to its outlet socket, which is connected to the ventilation shaft.

There are also turbine-type geysers. They are not connected to the ventilation shaft, they draw in combustion air from the outside and bring the exhaust gases out. Such water heaters are used in residential and industrial buildings in which there are no chimneys.

Security systems

Since any gas equipment is potentially dangerous, manufacturers equip columns with sensors. They form a safety system of units that prevent the occurrence of emergencies.

Table 3. Sensors for gas water heaters

The device weighs 19.5 kg, and its dimensions are 730 × 390 × 280 mm. The column is equipped with an electric ignition system. If the Neva column does not ignite, most likely the breakdown is a malfunction of the heat exchanger. It is eliminated by flushing the pipeline.

Gas column Neva Transit

We will consider the operation features of the column of the Neva Transit family using the example of the VPG-EM model (there are also VPG-E I, VPG-E, EMT with a capacity of 12–24 kW, a capacity of 6–12 l / min). Flow-through units maintain the set liquid heating temperature in automatic mode.

The column has a gas modulation device: by changing the position of the rod, you can reduce the amount of fuel consumed and increase the heating efficiency. In addition, the amount of deposits in the heat exchanger pipeline is reduced, due to which the operating life of the unit is significantly increased.

How to choose a geyser Neva

We have already considered the main parameters that should be considered when choosing a gas column model. It also depends on how many sampling points the column should provide. So, for a small apartment, an excellent option would be to purchase the Neva 4510 model. A power of 17 kW is enough to provide hot water.

If a more powerful unit, the choice is obvious - the gas water heater Neva Lux 5514. According to many users, the price of the model is fully justified. In addition, it should be borne in mind that for many years you will not have to spend money from the family budget on the repair and maintenance of the unit.

The main problems and repair of the gas column Neva

Neva column does not light up

If the Neva gas column does not ignite, the first thing to check is the electronic unit that generates the formation of a spark. As a rule, the problem is solved by replacing it. It is quite simple to do this, for which you need to remove the front screen, then the mounting bolts are unscrewed and the supply wires are removed (the new unit is installed in the reverse order).

Why the Neva gas column does not turn on

Let's analyze the main causes of malfunctions of the Neva brand columns, due to which the equipment will not turn on and heat the water. They are typical for the entire model range. One of them is the lack of draft in the ventilation ducts. The problem is solved by cleaning the chimney shaft, for which you should use a ruff with steel fibers.

If the column has an automatic ignition system, you should check the operation of the generator, batteries (batteries), as well as the power button. Most often, the unit does not turn on due to the fact that the batteries are dead. It is enough to replace them with new ones and clean the contacts.

A weak pressure of water and gas supply (there is a spark, the column does not work) will also prevent the device from turning on. The solution to this problem will be to call the specialists of the relevant services, who must clean the highways.

Where to find spare parts for the gas column Neva

Spare parts can be easily bought from authorized dealers specializing in the sale of gas and water heating equipment. In most cities of Russia there are representative offices of various manufacturing companies where you can purchase certified products, which guarantees long-term operation of the devices. The same can be done in online stores (require quality certificates for the offered spare parts).

Water heaters are becoming more and more popular in our everyday life. So that circumstances do not catch us at the wrong moment, we strive to predict all situations.

For urban residents, hot water shutdowns have become habitual. In the private sector, the problem of water heating has never disappeared. It is for such cases that gas columns are suitable.

Types of devices

The geyser is a water heater. Gas is the main source of energy.

The main criterion is the characteristics of the device, its quality and price.

Conventionally, according to the technical characteristics, the columns can be divided into types:

• by type of ignition;
• by type of chimney;
• by power (on which the volume of heated water depends);
• for security;
• to size;
• for additional features.

As for the quality of the product, the popularity and fame of the brand can be decisive. In the domestic market, NEVA is a quality manufacturer. This is confirmed by many product reviews. The quality of components and assembly is a guarantee of the reliability of the device.

Note: NEVA 4511 column service life guarantee is 12 years from the date of installation, and warranty service is 2 years.

Column ignition

The ignition of the column means the ignition of gas, namely the method, in gas columns it happens:

• ignition manually;
• piezo ignition;
• electronic;
• microturbine.

Manual ignition is a rarity for modern speakers. In older models, matches were needed to set fire to the gas. These models are rare today.

Piezo ignition. By analogy with piezo electric stoves, to set fire to the gas, you need to press the button on the column panel. This method is still used in modern models.

Electronic. The most convenient and popular way. Reliability and efficiency in gas consumption make such models a little more expensive. By analogy with a car, a spark is created by a small battery, batteries are more often used. The column NEVA 4511 belongs to this model range.

As for microturbines, the current in them is generated by a hydrodynamic generator controlled by a water flow. The cost of such copies is much higher.

Columns with electric ignition are easy to operate. The gas is ignited automatically when the water tap is opened, thus you can save gas consumption.

Type of removal of combustion products

Atmospheric speakers are available for sale. They discharge combustion waste directly into the chimneys.

The branded range of NEVA columns is represented by HSV models from series 10 to 14, in various modifications.

Turbine columns are not connected to the chimney, they take oxygen for combustion from the outside and throw the combustion products out there. They are designed to be installed on any floor in a building in homes without chimneys. The higher price is justified by the convenience of their use, since it is much more expensive to build chimneys.

Power

The power of an instantaneous water heater is determined by the volume of water that it can heat. To heat a large amount of water, you will need a powerful unit.

According to their power, the speakers can be divided into:

• power from 17 - 20 kW (small columns);
• from 20 - 26 kW (medium);
• from 26 - 28 (high power).

Column NEVA model 4511 consumes 21 kW, but at the same time produces up to 11 liters of hot water per minute. For an approximate definition of liters per minute, take a look at this table:

The column NEVA 4511 is suitable for two points of water intake. If you need to use more points, it is better to take a column with more power. The NEVA 4511 column is the most compact of the entire series and is suitable for small spaces. More powerful speakers NEVA from the Lux series.

Safety in use

The geyser is a device of increased danger.

To simplify the use and prevent various accidents, the columns are equipped with additional sensors. Among which:

1. Ionization sensor. If the fire goes out, the sensor shuts off the gas supply.
2. Additional thermocouples. They work in case of failure of the ionization sensor.
3. Heating sensor. Monitors the temperature of the flow heater, i.e. regulates the temperature of the entire device, as well as the heating elements.
4. Water pressure sensor, the main task of which is to turn on or off the gas supply automatically when drawing water.
5. Temperature difference control sensor. The device for raising and lowering the water temperature, in case someone additionally opened the water, is implemented in the newer Neva Lux models, model 4514, 4513.
6. Gas and water pressure sensor. Control the flow of water or gas into the column. If the tap with water is opened, when it is turned off, the column will not automatically supply gas.
7. Safety valves. Shut off the water or gas supply in case of increased pressure in the system.

Features of domestic systems

This means that when the gas pressure drops below 13 mbar, the column continues to work.

At the same time, automation does not allow turning on the device at low pressure. Gas supply in our territorial latitudes is a secondary problem. The main task is to control the water pressure.

Take into account: the Neva 4511 column is switched on at a pressure of 0.2 atmospheres, but long-term operation under such conditions is undesirable.

An important advantage of the columns Neva and Neva Lux can be called a replaceable heat exchanger. Instead of buying a new column, it is enough to purchase a component part. It costs from 3500 to 4500 thousand rubles, depending on its type. In new models, a copper heat exchanger is installed, such a material is resistant to corrosion, but salt and scale deposits remain a problem.

Maintenance of the Neva

Solenoid valve failures often occur. When you open the tap, you hear the click of the electric ignition machine, but no gas comes out.

Gas flows through the solenoid valve to the burner. Its replacement is not difficult, just like the heat exchanger, it is sold separately. Mounted in the column with screws. The valve diameter is standard, therefore, knowing the model of your column, you can replace it in a matter of minutes.

For installation work on the installation of gas equipment, only professional specialists with permission to carry out work should be involved. Before installation, they check for gas leaks in the system.

Note: it is strongly not recommended to independently install any gas equipment, especially a column. Specialists, following the instructions, follow the rules for connecting to a gas source and plumbing system.

Pay attention to the manufacturer's warranty. You need to know in advance how to get it. Installation of the dispenser is only possible upon receipt of a commissioning permit.

For the first start-up of the device, it is necessary to call the service center specialists to obtain a mark in the warranty card. Only then does the guarantee certificate come into force. Also, the column must be installed officially, i.e. in coordination with local authorities of economic activity.

It would seem that all the additional functions built into the column are automatically adjusted. But this does not mean that nothing depends on you.

Master's advice: better limit the outlet water temperature. At high water temperatures, the formation of salts and scale on the heating element is accelerated.

Consider the hardness of the water in your piping system. Repair and maintenance in case of breakdowns must be carried out by qualified specialists.

It is necessary to clean the burners and the heating element, as well as to clean the entire device from dust and dirt. With proper use, the column will last a long time.
