Geyser Astra instructions for use. Gas water heaters "Astra": types and operating rules

"Astra" are produced Russian company"Heat exchanger". The company represented on the market has existed for more than 50 years. "Astra" columns are intended for hot water supply. They operate exclusively on natural gas. IN in this case combustion products are quickly removed through the chimney. Previously, the Heat Exchanger company was engaged in the production of water heaters of the KG series. However, today they are considered obsolete. Modern devices of the Astra series have many advantages.

First of all, it is important to mention the large combustion chambers. The power of some models reaches 20 kW. Speaker performance varies. At the same time, the consumption natural gas theirs is moderate. The models are quite simple to install. Chimneys for Astra geysers are installed with a diameter of up to 120 mm. The average model on the market costs about 9 thousand rubles.

Possible malfunctions of Astra 08 (VPG 8910)

The model uses a good burner, but the economizer under it may periodically fail. This often happens due to wiring faults. To repair the Astra gas water heater with your own hands, first of all you need to turn off the gas. In this case, there is no need to remove the device from the wall. To detach the front panel, you will have to use a screwdriver. The economizer is located behind the electrode.

In order to get to it, you should first tackle the block. The electrode in this model is secured with four screws. In this case, there is no need to touch the heat exchanger. After removing the electrode, it is important not to touch the pressure measurement fitting. Otherwise, its head will have to be replaced. The economizer is quite easy to remove. To do this, you need to unscrew only two screws, which are located on the left and right sides. Next you need to check his contacts. In some cases, they become dirty after using the column for a long time. If this does not help, the economizer will have to be replaced. Then it must be installed again behind the electrode. If after this the Astra 8910 gas water heater does not light up, you will not be able to do the repair yourself.

Characteristics of the Astra 10 speaker

The specified geyser "Astra" deserves a wide variety of reviews from consumers. First of all, the owners positively assessed the simplicity of the design. The model's thermostat is convenient. If desired, the traction is adjustable. The system can withstand high water pressure, so you don’t have to worry about the tract. The column also has a good economizer installed. simple is provided. A user can purchase Astra geysers of this series for RUB 8,200.

Repair of the Astra 10 speaker

If the Astra gas water heater does not light up, you can try to figure out the cause of the breakdown yourself. To do this, you need to remove the front cover, which is secured with screws. After this you will have to inspect the heat exchanger. If there is dirt on it, it should be removed. Next you will have to disconnect the electrode. In this case, it is important to follow all safety rules and not risk your health.

When making “Astra”, the pressure gauge fitting cannot be touched. Only a technician at the service center can inspect it. However, you can check the operation of the hydraulic column group yourself. To do this you will have to remove four screws. In this model, the economizer is located to the side, so there is no need to touch it. You should also not inspect the burner yourself. To ensure the functionality of the hydraulic group, you should examine its gas valves. They must be firmly fixed to the panel.

If there is dirt on them, it must be carefully removed. After this, the hydraulic group should be installed in its original place. The gas valves in this case should face the rear panel. If the column does not turn on after the procedures performed, then the model will have to be returned to service center for repair.

Characteristics of the device "Astra 15"

This geyser "Astra" has the following characteristics: the power of the model is 13 kW, and the productivity is 12 liters per minute at 25 degrees. Combustion chamber is provided open type. Ignition is carried out manually. Minimum temperature the column allows you to maintain it at 35 degrees. Natural gas consumption is 2.2 cubic meters per hour. Connection cold water carried out through a pipe with a diameter of 1.2 inches. The chimney in this case is provided at 120 mm. The assembled model weighs exactly 15 kg.

Consumer opinion about the Astra 15 model

This model mostly receives good reviews from customers. The design of the Astra geyser pleases many people, since the parts used are of high quality. Owners also note high performance. The design of the model is simple. If necessary, you can adjust the temperature. The system can withstand water pressure of as much as 7 bar.

The chimney in the presented design is securely attached. You should also add a strong frame to this. The model has a high-quality heating pad and breaks very rarely. It is also important to mention the thermostat, which is installed at the bottom of the column. It has a protection system. Today, these Astra geysers are sold at prices starting from 8,500 rubles.

Possible malfunctions of the Astra 15

Despite positive reviews about the model, it periodically fails. If the Astra gas water heater does not light up, you must first determine the cause of the breakdown. You can make a superficial inspection of it only if you remove the front panel. To do this you will have to use a key. After unscrewing the screws and removing the panel, you can inspect the heat exchanger itself.

In this model it is located under the tract. The electrode installed in the device is of high quality, but its contacts periodically become dirty. In order to clean them, you will have to completely remove the box. It is secured with screws, so in this situation you cannot do without a key. The model does not have an adjustment valve. The control unit can only be inspected by specialists.

The last thing you should check is the hydraulic group. It can be removed quite simply, but it will be problematic to secure it in its original place. This should be taken into account before removing the box. After disconnecting the hydraulic group, it is important to inspect the gas valves. If they are not installed securely, the part will have to be completely replaced. You can do this yourself. To replace it, you will have to purchase a similar hydraulic group. In this case, you only need to remember the model of the speaker and inform it to the seller.

Review of the Astra 16 model

The power of the model is 18 kW, and the productivity is as much as 14 liters per minute at a temperature of 25 degrees. In this case, the chimney diameter is 110 mm. The system can withstand water pressure of no more than 5 bar. Natural gas consumption is about 2.1 cubic meters. meters per hour. When assembled, the presented column weighs only 14 kg. Cold water is connected through a pipe with a diameter of 1.2 inches. The maximum heating temperature is 65 degrees. The combustion chamber of the column is of an open type, and it is ignited manually.

To understand how to use a gas water heater correctly, you should know its structure and operating principle. Regardless of the manufacturer and model, the water heater consists of six main parts: casing, exhaust gas collector, heat exchanger, burner, gas fittings, hydraulic fittings and ignition device.

The casing contains water pressure and flame level regulators, power and ignition buttons (if the device uses piezo ignition) and a display. The housing covers the main components of the water heater and gives it a beautiful appearance.

The exhaust gas collector is located on top. The chimney pipe is connected to it using a pipe.

In a turbocharged engine with a closed combustion chamber, the manifold is located lower and equipped with a fan. These are all Bosch models marked WTD (for example, Therm 4000 S WTD 15 AM E), Neva Turbo, Neva Lux 8224, Neva-Transit VPG 10 EMT. Columns from Oasis and Astra come only with an open combustion chamber.

The heat exchanger is the main and most expensive part of the device. This is where heat is exchanged from the flame to the water. It consists of a shell and pipes through which a stream of hot air passes. Expensive heat exchangers are made of copper without impurities, which is evident from the uniform color of the metal.

The burner is located under the heat exchanger. It is designed to distribute the gas flow. The gas entering the column enters the burner, where it is split into several streams. This expands the flame and allows the heat exchanger and water to heat up quickly.

The gas fittings of the water heater control the gas on and off. It is connected to hydraulic fittings. In the Neva and Astra columns of the old model, the water-gas system is located vertically - there is a gas fitting on top. In new models of speakers Neva 5611, 4511 (how to use speakers Trademark Neva read), Oasis location is horizontal, hydraulic fittings are located on the right.

The ignition device is located near the burner. It consists of two electrodes; when electricity is applied to them, a spark appears. Can be semi-automatic, which needs to be ignited by a button that is placed on front side columns. These are all Bosch models with the letter “P” at the end of the marking, for example WR 10-2P.

Also, ignition can be automatic due to installed batteries or connection to the mains. Installed in most new devices.

The electrical circuit of geysers includes the following elements: batteries or power supply, control unit, screen, protection devices, ignition and flame control electrodes.

Batteries or power supply are connected to the control unit. Wires go from it to traction and water overheating sensors, a screen and electrodes.

If the column uses piezo ignition, then there is an additional ignition button for the igniter.

The video below provides an overview of the device and other everyday nuances of the Vaillant geyser:

Principle of operation

When the tap is opened, water flows into the water regulator. At the same time, pressure is created in it, from which the rubber membrane bends. It moves the rod, which in turn opens the gas valve in the gas fitting. Then the water goes through the heat exchanger pipes to the tap.

The gas enters the burner and is ignited by an igniter or spark between the electrodes. The flame heats the heat exchanger and the water passing through it.

Terms of use

In a number of water heater models, there is a power button on the front side of the housing that must be pressed. If it is not there, then most likely the column is already ready for use.

If you have a semi-automatic water heater with piezo ignition, then first of all you need to light the pilot light. To do this, you need to press the corresponding button on the case.

Columns with electric ignition turn on automatically when the water tap is opened. After closing the tap, the flame goes out automatically.

To use a gas water heater correctly, it is important to follow a number of operating rules:

1. It is undesirable to heat the water too much - this leads to rapid wear of the device. Modern columns allow you to heat water up to 70 degrees. It is recommended to set the water heater to 35-40 degrees, which is sufficient for domestic use.
2. It is not recommended to mix cold water from the tap with hot water from the tap. This leads to a drop in pressure and the heater going out. You need to set a comfortable temperature in advance.
3. From time to time, preventive maintenance should be carried out - checking the draft force, changing water filters, cleaning the chimney and burner from soot.

In this article we will present one of the types of geyser Astra. A device such as the Astra geyser has gained great popularity among Russian consumers due to its convenient functionality, as well as its simple design and very low cost.

The data has long been available on Russian market and are presented in all sorts of models that differ in power and performance.

1 Advantages of Astra geysers, their characteristics

The main advantages and features of the Astra geyser:

1. The design of the Astra geyser is very simple and accessible to any user.
2. It is not crammed with unnecessary functionality, which affects its low cost.
3. It has a productivity of up to 12 l/min (this productivity is quite enough for two water intake points).
4. Reliability of the device.
5. Setting up the Astra geyser is carried out according to the instructions included in the kit upon purchase.

I would also like to add that such a column has a simple design and the availability of spare parts that can be purchased freely on the market in the city. It should be noted that you can buy an Astra gas water heater in any online store at an affordable price.

If you look into the details, you should mention the presence of large combustion chambers in such geysers. There is even power that reaches 20 kW. But the performance of a gas water heater varies and the consumption of natural gas also varies, but in most cases it is moderate.

If we talk about the parameters of the Astra 8910 geyser, then its power reaches 12 kW. The thrust in this column is self-adjustable. If we ask about its maximum temperature, it will be 60 degrees Celsius. The thermostat in this column is located at the bottom. You should pay attention to the smoke exhaust pipe - it is wide. But the regulator on the Astra 8910 column is located under the central fitting.

This type of speaker has a durable frame that can withstand any load. There is also a protection system for the power supply. It should be noted that the fitting is adjusted using a special screw.

When purchasing this water heater, the kit includes instructions for the Astra 8910 geyser. Reviews of the Astra gas water heater can always be found positive, since the gas consumption is 2 cubic meters. meter per hour. By our standards, this is a good saving. If the Astra gas water heater has a power of 12 kW, then this consumption is very good. This heating device has a high-quality pressure regulator. The traction in this case is checked very simply.

It should be noted that combustion products are removed quickly from this model of geyser. The speaker also received high reviews regarding safety. There is no risk to human health when using speakers.

The consumer also noted the low cost of the product. For 7-10 thousand rubles you can buy a normal, average Astra speaker for your home.

2 Breakdowns of Astra geysers, and ways to fix them.

First, in order to repair the Astra gas water heater, the gas in the pipe is shut off. The speaker itself does not need to be removed from the wall. The front part of the device is removed using a screwdriver, unscrew the bolts on the sides. First, the economizer, which is located behind the electrode, is checked. The electrode is also not easy to remove. It is mounted in the Astra column with four bolts. We do not touch the heat exchanger.

Everything unscrews very neatly. This is done in order not to touch the fitting, which is used to measure the pressure in the device. If you suddenly touch or damage the pressure measuring fitting, you will have to change the head. But the economizer is very easy to remove. To do this, you only have to unscrew the two bolts on the sides of the column.

You also need to check and pay attention to the contacts; they often become dirty. If the contacts become unusable, they should be replaced with new ones. If after replacement the economizer does not work, then it will have to be completely replaced. These are the main malfunctions of the Astra geyser. The same repair mechanism and main malfunctions of the Astra 8910 geyser.

The first breakdown is when the Astra gas water heater does not light up. What to do? The most common problem with this is that there may be a lack of draft in the ventilation passage. Checking the draft in the chimney is very simple. You must first turn off the gas water heater and bring a burning match to the chimney outlet.

If the flame enters the chimney, then everything is in order and you can connect it again. Cleaning a chimney with your own hands is easy; if you doubt your own abilities, it is better to call a special specialist.

Does the Astra gas water heater not light up, or does it go out immediately? In this situation, you need to adjust the supply of cold water to the column. The main thing is not to try to dilute cold and hot water together, this can lead to a sudden extinguishing of the flame.

Astra - geyser

In the future, we have a question, how to configure and? To do this you need to have the following tool with you:

1. Pipe wrench.
2. Two types of adjustable wrench.
3. Phillips and flathead screwdrivers.
4. Set of paronite and rubber gaskets.
5. A regular rubber hose 1-2 inches, with a metal clamp attached to it.
6. Regular descaling agent (ordinary vinegar will do).
7. A container for draining liquid in the column.

Also, the hydraulic group in Astra geysers often fails. It's easy to take off, but putting it on is problematic. Once you have disconnected the hydraulic group, you need to inspect the valves. Such valves must stand firmly.

If there are the slightest shifts and lack of density, then the parts need to be changed. You need to buy parts for the hydraulic group and know the model of the gas water heater. The solenoid valve of the Astra gas water heater also often fails. It is often clogged with soot to prevent an explosion.

The use of flow-through gas columns has certain features.

Therefore, for trouble-free service of such a device, it is worth following the rules for its use. Security also depends on this.

Basic Rules

First of all, you need to remember that any devices using gas have increased level danger.

The same applies to operation. Therefore, they are subject to handling rules similar to other household gas appliances.

So, if you suddenly smell gas:

1. You must immediately turn off the gas supply.
2. In order to quickly reduce the gas concentration, it is necessary to open the windows and ventilate the room.
3. Until the house/apartment is completely ventilated, you should not use any electrical appliances or light a fire.
4. After this you need to call the gas service.

It is important to know: installation and connection can be carried out or only by certified specialists, in accordance with the approved gas industry project documentation.

Most often, a user manual comes with the device itself. So, if you have an open type geyser installed, then:

1. Do not light a fire in the burner or use it in case of reverse thrust in the chimney or the absence of one at all.
2. Without first studying the instructions, it is prohibited to use the “scientific poke” method to turn on the device or ignite the gas.
3. There must be a constant flow of air in the room where such a unit was installed.
4. It is strictly forbidden to make any changes to the design of the gas water heater.
5. To prevent burns, you should avoid touching the parts of the front panel located next to the inspection slot, as well as the chimney elements.

Note: It is better to turn on an open-type geyser at low heating power and not use mixers to obtain hot water. The reason is that in the case of strong heating of the heat exchanger, an intensive process of salt deposition occurs.

Checking traction

In this case we're talking about about options for geysers with an open combustion chamber.

It is also worth noting that modern options atmospheric speakers often already have automatic safety systems (most Astra, Bosh and Vaillant models). They prevent the column from starting if there is no traction, and will also turn it off if it disappears during operation.

However, you should not rely on the fact that automation will give you a 100% guarantee of safety. Therefore, it is necessary to be able to check traction yourself. For this purpose, professionals use special measuring devices that evaluate the presence and strength of air movement (draft).

But common man It is unlikely that such devices will be found at home. Therefore, the usual “old-fashioned” methods are used:

1. The first method involves removing the front part of the device and, taking a small strip of paper, bringing it to the chimney. If there is traction, then the paper will be pulled inward a little.
2. The second option is simpler and does not require any manipulations with the device itself. It will be enough to light a match and then bring it directly to the viewing window, which is located on the front panel. In the case when the flame is drawn into it, this will mean the presence of draft.

Good to know: quite common situations when the chimney works properly, but there is no draft. This may occur due to the fact that there is no air flow into the room, which is why there is no draft (air movement). To check this, you can close the windows and doors during normal operation of the chimney and check the draft.

How to turn it on

First of all, it should be noted that device options that have closed chamber or an automatic ignition system, it’s very easy to start.

The situation is different with models that have an open chamber. The reason is that in order to properly ignite the column, you first need to turn on the igniter.

To do this, open the gas valve and press the manual piezo ignition button, after which the wick is ignited. Then, using the regulator, the required temperature level is set.

Note: When starting any model, there must be water in the heat exchanger. Therefore, you must remember to turn on the water before starting the column.

If you have a device with an automatic ignition system, the actions should be as follows:

1. First you need to insert batteries into the compartment.
2. After this, open the gas tap.
3. Now the hot tap opens, due to which the burner itself will ignite. In this case, the intermediary will be the igniter, which is turned on exclusively for the duration of the gas burner startup.

There are cases when, after the first start-up or a long break in work, gas turbine A so-called air lock may form. It can be eliminated without any problems by performing the ignition procedure several times in a row.

Using modern geysers is, by and large, not difficult. The most important thing is to always follow all the safety rules specified here, and also not to allow the heat exchanger to heat up excessively.

Watch detailed video instructions on how to properly light an open-type gas water heater:

The Astra speaker sold quite briskly in the late nineties and early two thousand. A gas water heater was produced in Nizhny Novgorod

The speaker is quite powerful. Gives boiling water easily. I won’t rip off the description from the passport. I would like to tell you about the problems that I most often encounter when repairing these water heaters.

The column, with minor modifications, borrowed the water block from the notorious so-called “Stalinist” column KGI-56. The size of the water block membrane is the same (the membranes are interchangeable). The bottom of the water block is different. In Astra, the water pipes to the block are connected from the side, while in KGI-56 it is from the bottom or from the rear wall. The failures in the block are the same - leaks from the rod seal, deformation or rupture of the membrane (the main burner does not ignite). It is not the design of the water block itself that has gone downhill, but the material from which it is made. On the Astra HSV it is made of aluminum alloy, which is much worse than brass or bronze. Over time, especially if there have been leaks in the water block, silumin is very strongly oxidized and it becomes impossible to disassemble the block to replace the membrane. It’s good if you can unscrew the tubes from the block to replace the entire block. By the way, the price of a block for this rarity is also steep - about 1000 rubles.

The gas block with two levers is the same as that of the KGI, but modified. This geyser has a safety automatic, consisting of a thermocouple and a solenoid valve. There are both failures of thermocouples and valves. Gas is supplied to the column igniter from the gas block, and the air for combustion of the igniter is taken from the top of the column. This was not done by accident. If there is no draft in the chimney, then carbon monoxide enters the room at the top of the column. The air intake for the igniter is also located there. If there is no draft, the oxygen required for combustion is no longer supplied to the igniter, and it goes out. Accordingly, the thermocouple cools down and closes gas valve. This is how protection against lack of traction is implemented in this column. I have never seen this on any other mass-installed speakers.

Another “bottleneck” point of this column is the tubes going to the heat exchanger. The tubes are connected to the heat exchanger using union nuts. Gaskets gradually shrink due to temperature changes and begin to leak. Since the tubes are copper and the union nuts are steel, this connection boils very quickly so that nothing can be used to unscrew it. We also came across tubes that began to leak over time (through corrosion).

Problems with heat exchangers are rare. The walls of the combustion chamber are made of heat-insulating material.

Let's summarize. A quite common dispenser with poor maintainability of the water part. Because of this, many craftsmen simply do not like to repair them. The gas part and heat exchanger usually do not cause problems.
