Overview of the types and characteristics of gas boilers Neva lux

Description of the gas wall-mounted boiler Neva Lux 8224

Double-circuit gas wall-mounted boiler Neva Lux 8224 with a closed combustion chamber is intended for apartment heating and hot water supply in multi-storey buildings, as well as in private suburban areas up to 240 m².

Security

Gas wall-mounted boiler Neva Lux 8224 absolutely safe to use. The manufacturers have provided for all possible emergency situations. The gas supply to the boiler is automatically stopped when the burner flame goes out, the heating medium heats up to a temperature of more than 90 ° C, irregularities and problems in the smoke exhaust system, power outages, and also when the pressure drops below the maximum permissible level.

Built-in functions of anti-freezing, automatic protection against blocking of the pump, "acidification" of the three-code valve. If the pressure in the heating system rises above 3 bar, the coolant is discharged.

In the event of a malfunction, an electronic self-diagnosis system displays error codes on the display.

Separate heat exchanger system

The gas boilers Neva Lux 8224 have two heat exchangers: a copper one for the heating circuit and a secondary stainless steel plate heat exchanger for hot water supply. In practice, this means that hot water supply and heating are less dependent on each other than when operating boilers with a bithermal heat exchanger. In addition, boilers with separate heat exchangers are less demanding on water quality.

The use of a system of two separate heat exchangers can significantly reduce the likelihood of scale formation in the primary heat exchanger, thereby reducing service costs and extending the life of the device.

Additional features

Everyone who wants to buy a gas boiler Neva Lux 8224 can choose the options he needs: connecting an outside temperature sensor, room thermostat, indirect heating boiler, remote control, etc.

Neva luxury boiler, instruction manual

In accordance with the completeness of the Neva Lux gas boiler, together with the device itself, there is a warranty card, fasteners and operating instructions in the package. It contains all possible variants of breakdowns, methods of connecting the device to the heating system and much, much more. From the point of view of specialists, there is nothing complicated in operating a heater. All issues are completely solvable on their own. The only thing that should be taken into account is that if the equipment breaks down, it will be necessary to call a specialist, otherwise, if the user tries to repair the device on his own, he risks harming not only himself, but also the premises, as well as his loved ones. Gas is a dangerous, explosive material that, if handled incorrectly, can lead to irreparable consequences.

Gas boiler Neva lux, malfunctions

Any equipment can fail, gas boilers are no exception. For example, the most common malfunctions that occur with this boiler:

• Low gas level in the system;
• Extinction of the flame;
• Low pressure in the heating system;
• Malfunctions from physical impact.

If something fails, then you need to contact the technical support service. It is not worth solving the problem on your own, because the guarantee is valid only if the integrity of the device is not violated, which is impossible with self-repair.

Price for gas heating boilers Neva Lux

Heating equipment can be purchased at a fairly affordable price, because the equipment is designed for the middle class, i.e. on the general population of the Russian Federation. All heaters of gas type Neva Lux are in the price range from 12,000 rubles to 32,000 rubles.

History of the Neva company

Russian users are well aware of the Neva Lux single-circuit and double-circuit wall-mounted gas boiler. But not everyone knows that a company that produces 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 columns, boilers, heaters. Currently, the company belongs to the largest concern Baltic Gas Company.

Thanks to this alliance, such models as Neva Lux and a new product on the market - the Turbo model, appeared. Deficiencies 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.

Specifications

Wall-hung gas double-circuit boilers Neva Lux

Various modifications of gas boilers Neva Lux are suitable for heating homes, industrial and office buildings. Their modifications heat rooms with different areas. High reliability and "smart" automation brought these boilers to a leading position among Russian manufacturers.

Specifications:

• Thanks to the powerful gas supply pump, they can work in low pressure systems. The pump itself will create the necessary conditions, depending on the settings.
• Copper heat exchangers have higher efficiency than cast iron and steel models.
• All major movements are made in Italy. Localization of production is limited to the manufacture of the body and unimportant parts. Cooperation with foreign partners, the use of European technologies has a beneficial effect on the quality and economy of the product.
• Foreign technologies provide 100% security.
• Easily adapt to specific operating conditions.
• The efficiency reaches 98%.

Thanks to the cooperation of European manufacturers, the consumer is provided with a technological and reliable device of high quality.

Lineup of gas boilers Neva

The units manufactured by Neva are subdivided into two series: Lux and Turbo. Devices belonging to the Lux series are divided into two categories:

1. Single-circuit wall-mounted gas boiler Neva Lux. Designed only to supply the house 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 a modulating burner is included in the package of the device, which can change the intensity of combustion based on a given temperature regime, the device is highly economical. Boiler operation can be converted to liquefied gas. Gas single-circuit wall-mounted boilers Neva have found a wide demand from users also due to their low price, simple maintenance, as well as the absence of volatile nodes that are subject to voltage drops in the network.
2. Double-circuit wall gas boiler Neva Lux. These devices have open and closed combustion chambers, as well as a bithermal heat exchanger. The chimney can be either coaxial or traditional. The process of heating the coolant is controlled by highly accurate automation. The maximum distortion from a given 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 underfloor heating.

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 it is in the room.

Boilers Neva Lux - Repair and maintenance

• Errors of the Neva Lux boiler and their meanings

The gas wall-mounted boiler Neva Lux 8224 (BaltGaz) is in operation. Starting it up, I found out that the burner did not start. Before the start-up, on the new, just purchased, the following measures were taken: Mounted jets for liquefied gas; A jumper is installed to operate on this fuel; It was reprogrammed. If you hold down the "Reset" button until the moment when the "little man" lights up, you can start it. He has a good flame - a normal blue color. The heating system is working properly, warm water is supplied to both the radiators and the warm floor. In summer mode, when the DHW is started, it also does not want to work. It ignites the gas and immediately goes out, and so on several times. It starts working only after manipulating the reset button. That is, the problem is observed in both summer and winter modes. Confused - entry and exit, because they could not figure out the designations on. But I have a water gun installed, and so it shouldn't be a problem. Why can there be problems like me? I have a system of three gas cylinders installed, which are connected to each other by a hose through tees and through reducers. I did not check the gas supply pressure. Logically, even if there is a malfunction somewhere, the pressure of the remaining cylinders should compensate for the missing one. The simplest reducer is a frog for gas cylinders. Will different gas supply pressures affect combustion? If, before, then how? The jets were delivered according to the technical instructions. When reprogramming to work with liquefied gas, only the ignition power was changed. The jumper is installed correctly. Where to look for the problem? Faced a similar problem on NevaLux and didn't have enough experience to solve the problem myself. But in fact, everything is simple there. When new nozzles were installed, it was necessary to dismantle the flame sensors (metal contacts in white ceramic insulation). So it was these contacts that turned away from the flame during installation and stopped seeing it. The unit received a signal that there was no flame, and there was a constant ignition. The problem was discovered by a specialist from the service center, by checking all contacts one by one. This may be a design defect and occurs on all models. The specialist, so that I do not lose the warranty, made a note in the service book about the presence of such a problem. I cannot solve problems with fine tuning and adjusting parameters through the remote control - neva lux on the baltgaz 7224 gas boiler. The manual assures that it is possible to control the temperature maintenance mode parameter by modulating the flame or by turning the device on and off.However, when I enter the menu, in the parameter "P01", the temperature scale appears, instead of "0" - turning the device on and off and "1" - flame modulation. Tell me, what then is the program for fine tuning the boiler? What is written in the instructions does not correspond to reality. P1- means the power supplied by the ignition (for smooth operation). P2 - heating power. It is exposed based on the size of the heated room. I have a house of 48 sq. m. To heat it, I bought and installed a Neva Lux 8618 wall-mounted boiler. I chose this particular model, since in the future I plan to increase the heated area to 90 sq. m. m. The heating system consists of 6 aluminum batteries with six sections (total power 6912 W). Recently I read in the instructions that for the installation it is necessary to take into account its characteristics and the characteristics of the heating network. For this model, the minimum heat transfer should be at least 8.9, and mine is 2 kW less. Is this critical, or will I be able to work through the winter like this, and solve the problem in the summer? I just do not like the phrase from the instructions about the instability of work and a decrease in the service life. Nothing bad will happen. However, you will need to connect a room thermostat and make additional settings. Take the most common thermostat, working on / off principle, no need to take the programmable one. But keep in mind that the numbers on the spinner do not always correspond to the truth. Two years ago, I installed a gas boiler Neva Lux 7224 at my home. The connection was organized through IBPS-12-350K Sibkontakt. It already has the third board, now it's neva pcb rev7. The first fell into disrepair during a thunderstorm. The R65 unit is faulty on both boards. Now the new boards have become expensive and I thought about repairing. Is it real? Check the ignition electrode gap. These boards are very sensitive to it. Perhaps this is the problem. Is it possible, before blindly buying a new DHW sensor, to check if it is not working? All sensors can be checked by resistance, and the DHW sensor is no exception. The value should be 1 kΩ at 25 degrees. I have a gas boiler Neva Lux 8023 installed, moreover, since I am going to use it with liquefied gas, it was reprogrammed. I also changed the nozzles to 0.79, adjusted the minimum and maximum gas pressure. But I did not do something, because there are no problems with heating, but the water for household needs does not rise above 27C. The water pressure itself is average, but even if it is further reduced, it does not help much at 50C, the maximum to which it was possible to heat the water. I measured the water flow at the inlet, it was 20-30 liters per minute. Where to look for the reason? Look at your passport. And bet the maximum you can. When hot water is in operation, Neva Lux 8224 (installed in 2009) does not maintain water at the same temperature. It gets hotter and colder. The device does not show any errors, it works as if it was in good working order. From the nuances: six months ago, when the water was turned on for household needs, he began to howl and make extraneous sounds. And when the heating is working in the boiler room, there is silence. The water pressure is good. What could have broken? Pay attention to the cyclical operation, that is: turning on and off when heating. And see if the uninterrupted water supply is being observed (you need to look at the flashing pictogram). Most likely, it is time to carry out maintenance. You have problems with the heat exchanger, a lot of water has already passed through it, and it has grown corny from the inside. Correspondingly poor heat dissipation. And the cyclical nature of the work is precisely because of this: it is already heated to the maximum, but there is still no water on the hot water supply. Since there is a problem with heat dissipation, it turns off and waits until it cools down. Then it works again. But heating is still a problem, that's the temperature drops. Neva Lux 8230, all summer was off. In the fall of this year, it was necessary to partially heat the house - it became chilly. After turning on, it normally ignited, and then a problem appeared.The device very quickly raised the water temperature to the required one and turned off. Thought the pump had jammed. Dismantled it, turned the shaft with a screwdriver - free movement. Asked different speeds of work - everything is correct. And still, quick heat up and stop. And also the outlet nut on the pump gets very hot. It feels like something is stuck in the pump and the water does not pass any further. Is it possible? Check the three-way valve actuator. It happens that contact leaves and problems begin. Neva Lux 8224 (Baltgaz), discovered the following problem: the post-circulation pump does not turn off, no matter what the temperature is. To make sure that this is so, he raised the temperature in the heating system to 60C. He turned off the flame. Then I set the temperature in his settings to 30C, so that it would stand in the pause mode for a longer time, and began to observe. The pump did not turn off for a second. And as I understand it, it is impossible to control it from the outside? In theory, if the basic settings are set, then the post-circulation pump should work for 3 minutes. There is a parameter P3, it is he who sets the minimum time from stopping the pump to turning it back on. The adjustment range of this parameter is from 0 to 14. Try to play with this value, for example, put 5. If the situation does not change, then this is a software failure. After an emergency shutdown of the gas, error 01 is constantly displayed. Restarting did not solve anything. There is no water heating. How to fix? Try restarting first. It does not depend on the phase, so if the boiler does not see the flame, then it really does not exist. It is also possible that you have an air lock in the pipe, or something is interfering with the flow of gas. Check it out. I have an outdated and discontinued Neva 7023 boiler at home. When I plugged it in, I heard a loud sound. After that, he refuses to work. The called specialist said that the board burned out and replaced it. Still, the work was not perfect. Once every couple of days, it turned off. We installed a room thermostat - the master advised us to do this. And after that, the E7 error began to pop up constantly. Again I had to turn to specialists. They thought for a long time and turned off all the buttons on it so that the adjustment was only from the thermostat. He worked for a couple of days and got up again. And it did not work to start it with the "reset" button, as it was possible before. Should I summon the master again? And so every time? In winter? In your boiler, an E7 error means that the coolant temperature has exceeded the permissible value. There may be several reasons for this: Broken temperature sensor. Incorrect settings were made after installing the new board. The fee itself came across to you with a marriage (this rarely happens). You forgot to carry out maintenance for more than two years and your heat exchanger is clogged. Or rather, the circulation of the coolant is disrupted. Neva Lux 8624 does not want to work in winter. If the outside temperature is below -25, then error 03 immediately appears and he gets up. There are two ways to start it: Reboot. Blow out condensation from silicone tubes. Installed it in 2010 and all these years there was such a problem. Everything else is fine and works fine. What can be done to fix the defect? The problem can be solved in several ways: Put a silicone tube from Vaylant (it still has a hole in the transition between two pipe cuts). Take a silicone tube and insert a medical needle into it, so that the diameter of the hole is about 1 mm. And direct the needle towards the pitot tube. Make a hole in the pressure switch with a diameter of 1 mm. Perhaps the error itself is not due to condensation. Frosting on the end of the tube can interfere with the air flow and cause problems. I installed a new boiler (produced by Baltgaz), but myself, since it took a long time to wait for specialists, and it was rapidly getting colder outside. So I obviously don't have a guarantee, I'll have to figure it out myself. It was launched strictly according to the instructions. Filled with water, blew air from the pump.I did not count on the heating system itself, but I checked all the nodes for air jams. There are no problems, except for a warm floor in one room, but there is a problem with installation (a branch from 32 pipes to 16, without a comb and an additional pump), apparently it cannot push water through such a constriction. Another pressure gauge is installed on the system, and its readings coincide with the readings of the unit. There is an Italian pressure gauge on the return line, and it shows 1.8 (when the readings on the boiler are 1.5). Want to understand what the problem is? Maybe I can fix something myself? Yes, and if I call the master, I would like to protect myself from unnecessary and meaningless spending, at least roughly representing the direction of the repair. I have filters installed on the water: the main one on the incoming water (thread, 5 microns), and on the hot water supply (polyphosphate). Everything is as recommended by the manufacturer. If you turn off the DHW circuit, then there are no problems in operation. And it is also connected in a level way: Resant stabilizer 3 kW; UPS 3.5 kW with online conversion. Since we have sudden power outages, I decided to protect myself in this way. In your case, it is recommended to contact a service organization. My Neva Suite 8029 is broken. It completely ignites and the E2 error lights up on the display. When water is supplied, there is no spark (ignition transformer does not work). And after all this, the fan on the hood works and is not going to turn off. And it works even if you turn off the front panel with a button. I checked the transformer circuit, since the relay clicks when triggered. But I do not know what the voltage should be in order to check it with a tester. Tell me? A voltage of 220V is supplied from the board to the ignition unit. To check, you can connect a normal live wire, the board should start clicking to supply a spark. If there is no reaction, then the ignition unit is definitely broken. Buy a new one, they are not repaired. I have a NevaLux 7023 double-circuit boiler installed. Recently, it began to lose pressure when working with hot water supply. At the same time, the number 95 is lit on the indicator and an error E7 appears. This does not heat up the water. If you reduce the water pressure, then the pressure stabilizes, and the error disappears. The numbers on it become 48, and the water temperature is already high enough. But not for long. Then the problem repeats again. With all this, heating works perfectly. What could have caused this problem? And how to solve it? A malfunction has occurred. In the summer, we did not need hot water, not heating, but the time came when we needed to turn on the boiler, but at startup, a problem with circulation was discovered. I called specialists who diagnosed a pump breakdown and for about a week have been trying to find a replacement for it. I am also lucky that the unit has a slope and can work without a pump. True, it now works in a cycle: it works for 2 minutes, it costs 2 minutes. I have a Neva Lux 8029 and a Wilo NFSL 12/4 pump. Is there any way to fix them? The pump heats up slightly more than the incoming water. Try to turn the shaft inside the pump by first unscrewing the screw. If the shaft is jammed, then this is definitely a purchase of a new one. In order to avoid such a problem in the future, you should not turn off the pump, it is enough to switch it to summer mode. Then the boiler itself will periodically circulate and the pump will not sour. A long time ago my Baltgaz boiler broke down. All hands did not reach to fix it, since I still have an electric boiler. But all the same I decided to do it. I decided to check the secondary heat exchanger. And it cannot be removed, because of the engine of the three-way valve (there is no access to one of the hexagons). As a result, I disassembled everything and removed the heat exchanger. Then I washed it very thoroughly with water. A large number of various small stones (flat and dark gray) were washed out of it. But, despite their presence, the flow through the heat exchanger was still preserved, although it was difficult. Tried to buy a special flushing solution, but all the shops were already closed.Then I decided to use cola. He warmed it up and poured it into a heat exchanger. Then I used citric acid - soaked in it for an hour. I washed everything again, although I did not see any special changes. It should be noted that the stones were only on the heating side. I began to check the sensors and the three-way valve further. The sensors reacted as it should, from which I concluded that they are completely serviceable. Next came the turn of the three-way valve. Having disassembled it, I did not find anything wrong. The spring is tight, the rings are intact, the valve itself is without burrs. Confused only by the fact that the resistance of the engine instead of 15K, was only 9K (maybe different models?). When I put everything back, it worked. I also cleaned the sump on the return, it was heavily soiled.

Neva Turbo boiler

On the quality and ease of use, users left various reviews: 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.

All the shortcomings were taken into account here. The technical characteristics of the models are as follows:

• closed combustion chamber - here there is a forced supply of air by means of a fan. Smoke removal is carried out using a special device through - a coaxial chimney;
• 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 the equipment and the regulation of heating. The package includes an autodiagnostics system, which automatically checks, the results of which are displayed on the liquid crystal display;
• control - on the usual buttons. Using a conventional regulator, you can set the desired temperature regime, provided that the programmer is installed, select the conditions for operation for several days or a week. The optional kit includes a room thermostat. The sensor generates a signal to turn off the heating when the room heats up to the desired temperature.

Turbo boilers are volatile units. The electric power supply of the boiler is achieved by connecting it to a conventional 220 V mains.

New product of the company - boiler Turbo

As the Lux models were used, both negative and positive consumer reviews accumulated. Over time, all the necessary adjustments resulted in the production of a separate series of heating equipment.
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 specifications:

Turbo boilers are volatile. The power supply of the boiler is provided by connecting to a regular voltage network of 220 V. For stable operation, you will need to install a UPS and a generator.

Easy to maintain and operate

Regardless of the model chosen, the installation of a wall-mounted boiler takes place quickly and without the need for additional costs. The manufacturer focuses on the convenience of installation and subsequent operation. Therefore, the boilers of the company, in fact, represent a station already ready for operation.
It is enough to connect the unit to the heating and power supply system and start heating the house or apartment. In practice, provided that the heating system is already completed, all work takes about 3-4 hours.

Once installed, there is no need to worry about the safety of the station. The sequence of the automation completely excludes the possibility of gas leakage, creating an emergency, even if an unplanned power outage occurs.

The main differences between Neva boilers

A simple device and operation make it possible to distinguish Neva boilers among all domestic heating equipment. Today, in terms of their characteristics, boilers are in no way inferior to foreign equipment and have a more attractive cost.
The Turbo modification provides economical gas consumption and, if properly operated, pays for itself in a few years.

Calculation of the 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 apartment buildings and country houses. For the production of boilers, modern materials are used, as well as high-quality components from the best European suppliers. The designers of the enterprise are constantly researching, 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, the manufacturability of production increases and, which is important for gas equipment, the degree of its reliability increases. Domestic manufacturer BaltGaz has implemented two design options for gas by-pass boilers Neva Lux. So in the 72 series boilers, 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 72nd series products provide accurate temperature control with a tolerance of 1 0 C. The 82nd and 86th series models 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 by-pass boilers differ in thermal performance and minor design details:

• Nevalux-7211 - thermal power 11 kW, bithermal heat exchanger, maximum heating area - 110 m 2
• Nevalux-7218 - thermal power 18 kW, bithermal heat exchanger, maximum heating area - 180 m 2
• Nevalux-7224 - thermal power 24 kW, bithermal heat exchanger, maximum heating area - 240 m 2
• BaltGaz 18 DBF - thermal power 18 kW, bithermal heat exchanger, maximum heating area - 180 m 2
• Nevalux-8624 - thermal power 24 kW, copper heat exchanger (heating) and plate heat exchanger (DHW), maximum heating area - 240 m 2
• Nevalux-8224 - thermal power 24 kW, copper heat exchanger (heating) and plate heat exchanger (DHW), maximum heating area - 240 m 2
• Nevalux-8230 - thermal power 30 kW, copper heat exchanger (heating) and plate heat exchanger (DHW), maximum heating area - 300 m 2

The rest of the components of this heating equipment are similar to Nevalux single-circuit wall-mounted boilers. This is a modulated burner with continuous flame control, and built-in safety elements, and electronic control. All Nevalux wall-mounted double-circuit gas boilers are pre-configured to operate on both natural and liquefied gas, and the design features ensure stable operation of the equipment even with low gas pressure in the supply line.
Wall mounted gas boilers are in great demand among consumers who have a house or a small cottage. This is due to the advantages of this type of equipment. Thus, the wall-mounted boiler is distinguished by its small external dimensions, due to which the equipment can be installed indoors with minimal loss of space.

Error E1 - no flame

Ignition clicks for about a minute the burner does not ignite. The electronic control unit does not see the presence of a flame and the column goes into emergency mode.

Reason # 1. The presence of air in communications. Prolonged downtime of the column, or after its installation, the operation of the ignition burner will occur only after air has been removed. The system should be purged by constantly turning on the column. Since the ignition lasts no more than a minute, after completion you should reopen the water tap until the ignition occurs.

Reason # 2. Lack of gas in the cylinders or the valve on the lowering to the dispenser is closed. Open the shut-off valve fully. Check LPG cylinders. Replace them if necessary.

Reason number 3. There is no contact between the unit and the flame detector. It is necessary to service the contacts coming out of the electronic unit, if necessary, clean them, press them for a good connection, replace the worn ones.

Reason number 4. Flame presence detector outside the flame zone. Adjust the position of the flame detector so that its electrode is in the gas combustion zone. Make sure that the electrode does not touch other metal components. Clean the electrode from carbon deposits.

Reason number 5. The gap between the ignition plug and the igniter is broken. From constant heating and cooling, the pilot burner nozzle is deformed, which increases the gap to the spark plug. Once every two years, or with a regulated maintenance, the gap should be adjusted to 4… 5 mm.
