Despite the fact that today the networks of housing and communal services are universally upgraded, the quality of the services they have remained at a low level. This is especially true of hot water. To solve this problem, the gas water heater should be purchased once and forever. However, it is necessary to decide which model will suit you better than the rest.
Modern manufacturers offer mentioned devices in a wide range. They have certain operational and technical characteristics. You can classify columns on flow and accumulative. As for the first, they have smaller sizes, which allows them to be installed even in a small room. Cumulative gas water heaters May accommodate from 50 to 500 liters of water.
The design in the design has effective thermal insulation, which allows you to save high temperature Waters for a long time, it helps save energy resources. If you still can't solve which gas column to choose, you can pay attention to the equipment under the Astra brand, it will be discussed below. Such devices are good not only what they are manufactured in Russia, and therefore, they have an acceptable cost, but also maintainability. This indicates that in case of failure, you can figure it out independently.
If you want to save doubly, you should purchase a water heater domestic production. Such is the Astra gas columns. Consumers choose them for affordable cost, but this plus can not be called the only one. Work aggregates on liquefied and natural gas. Buyers like more high level The safety of the manufacturer took care of. After all, if the ignition burner is willed, then the water supply for heating will stop, it concerns and automatic gas supply.
Such water heaters act as an optimal solution for domestic use. Buyers like more ease of operation, as well as service. It does not have to spend on it. Appearance structures are attractive, the case has modern and stylish design. Any gas column of the manufacturer can enter the interior of the room. Astra gas columns, according to buyers, are offered on sale in a wide range. That is why you can choose the most optimal optionwhich will meet the requirements and preferences of the consumer.
If you are interested in the Astra gas columns, you should consider several models at once so that you have the opportunity to do right choice. Among other things, the market is presented in the market 8910-00.02, which is manufactured in Russia. Its power can reach 21 kW. Design is equipped open camera Combustion and manual approach.
Hot water productivity is 12 l / min. The supplied water may have a temperature that changes from 35 to 60 ° C. When working column consumes natural gas in a volume, which is 2.3 m 3 / h. The maximum water pressure can be a 6 bar. The smaller water pressure is equivalent to 0.5 bar.
Gas connection is carried out using communications that have the following parameters: 3/4 inches. Connect hot I. cold water It is performed using pipes, the diameter of which is 1/2 inches. The diameter of the chimney reaches 120 mm. If you are considering Astra gas columns, you must interest their dimensions. As for the models described in the section, its dimensions are 700x372x230 mm. Weigh equipment 15 kg.
In order to make the right choice, you need to consider several models. Among other things, the market is presented an OPG version 8910-08.02, the power of which reaches 18 kW. The design has an open combustion chamber and manual view ignition. The productivity of this model is somewhat less and is 10 l / min. The temperature of the supplied water remains at the same level, but the fuel consumption will be slightly smaller and will be 2 m 3 / h. The minimum and maximum working pressure of water remains the same. Connection is carried out with the same parameters. It remains the same diameter of the chimney. The structure of the design has identical parameters.
This gas column Astra 8910 has a power equal to 18 kW. Electric closure is carried out from batteries. Water performance is 10 l / min. Natural gas consumption is 2 m 3 / h. The chimney diameter in this case is somewhat different, it is equivalent to 135 mm. Two-year warranty is provided to this product.
The power of this equipment reaches 21 kW. Electric closure is carried out from batteries. Hot water capacity is somewhat larger, it is equal to 12 l / min. The consumption of natural gas remains the same as in the first of the models described above, this parameter reaches 2.3 m 3 / h. The chimney diameter is 135 mm. Weigh equipment 15 kg.
Among the main advantages of the equipment described in the article, consumers allocate:
Equipment, according to consumers, maintainable. All parts can be found in the service workshops. Yes, and the column itself is cheap enough. Buyers especially like large combustion chambers, so the power of some models reaches 20 kW.
Adjusting the thrust at the model 8910 is carried out independently. Thermostat B. this variant Located below. Smoke removal truck is wide enough, but the column controller is under the central fitting. The frame frame, according to the owners of the property, which have gained such equipment, is very durable, so it is capable of withstanding any load.
The power supply is provided for the power supply. Using special screws, you can easily adjust the fitting. The Astra gas column, the operating instructions of which comes in the kit, has, according to consumers, economical fuel consumption. The design has a high-quality pressure regulator. Craving can be checked very simple. Deleting combustion products occurs quickly. In response issues, the column wins other models.
Repair of the ASTRA Gas Column begins with gas overlap. The column can not be removed. The front part is dismantled with a screwdriver, but first you need to unscrew the bolts located on the sides. The first need to check the economizer, it is located behind the electrode. Remove the latter will be quite difficult. It is fixed on 4 bolts. Troat the heat exchanger is not worth it.
When you repair individual nodes, it is important not to touch the fitting, it is used to measure pressure. If this part is damaged, then you have to change the head. In order to remove the economizer, you need to unscrew only two side bolts. The consumer may well be repaired with their own hands. The Gas Column "Astra" has contacts in the design, which are often contaminated. If they come into disrepair, they need to be replaced. If the economizer does not work after replacement, it will also have to change it. These faults are one of the main columns "Astra".
If you encountered a problem when the Astra gas column does not light up, then it may indicate this for the lack of thrust in the ventilation passage. Check craving can be very simple. The gas column is turned off, and to the yield of the chimney should be reduced by a burning match. If the flame is fond of chimney, then everything is in order - you can connect the column. Otherwise, the chimney should be cleared. However, it is better to entrust this business to a special master.
The Astra gas column, the faults of which you should be considered during the operation of this equipment, sometimes immediately goes away after the ignition. In this case, it is necessary to adjust the flow of cold water into the column. Do not try to dilute hot and cold water, it can cause flame damage.
If you were purchased by the Astra 8910 gas column, spare parts for it during operation may be needed. It is necessary to know what their cost. For example, a water assembly will cost 1,600 rubles. Gas part costs 1 500 rubles. Magnetic cork has a lower price - 205 rubles. The membrane costs 25 rubles. Remkomplekt water part costs 155 rubles, and adjusting knot - 55 rubles.
If you still do not know whether it is worth purchasing a gas column of the Astra brand, then it should be considered in more detail its features. For example, copper heat exchanger All models have an enlarged wall thickness. This provides good heat transfer from heated gases to water, which saves. For more convenient operation The manufacturer provided the design with the display with which you can determine the temperature of the heated water.

The working circuit of the WGV-18 water heater is shown in Figure 3.
At the beginning of the water flow through the water 22 assembly (see Fig. 3) with a flow rate of at least 2.5 l / min, the gas rod 25 opens the gas valve 30 and the contacts of the microswitch 17 are closed, after which the electromagnetic valve opens the control unit 15 and begin to be fed. High voltage current pulses on a candle 10.
Razjign burner 5 comes from spark discharges between the electrode of the candle and the nozzle of the burner section. Next, the operation of the burner is controlled by the sensor for the presence of flame 11.
The water flow regulator 1 is regulated by the number and water temperatureemerging from the device: the rotation of the regulator counterclockwise increases the flow rate and reduces the water temperature; The rotation of the regulator clockwise reduces consumption and increases the temperature of the water.
The position of the regulator also determines the water consumption at which the device is turned on.
The gas flow regulator 2 is regulated by the amount of gas flowing into the burner to obtain the desired water temperature during its established flow: the rotation of the regulator counterclockwise increases the flow rate and water temperature; The rotation of the regulator clockwise reduces gas flow and water temperature.
When the flow of water is ceased or with a decrease in its flow rate to a value of less than 2.5 l / min, the contacts of the microswitch 17 are opened and the valves are closed 13 and 30. The burner goes out.

Operation and repair of boilersIn the title of columns produced in Russia, the LDV letters are often present: this is a water heating device (c) flowing (P) gas (g). The figure, standing after the letters of the WSV, indicates the thermal power of the device in kilowatts (kW). For example, WSG-23 apparatus Water heating flow gas thermal power of 23 kW. Thus, the name of the modern columns does not define their design.
WGV-23 water heater was created on the basis of WGV-18 water heater, produced in Leningrad. In the future, VSV-23 was produced in the 90s on a number of enterprises of the USSR, and then there is a number of such devices in operation. Separate nodes, for example, water partThe use of modern speakers in some models of modern speakers in some models.
Maintenance specifications HDV-23:
HPV-23 consists of a gas supply, heat exchanger, the main burner, block-crane and solenoid valve (Fig. 74).
The gas feeder serves to feed the combustion products into the smoke line of the speaker. The heat exchanger consists of a carrier and a fire chamber, stuck with a cold water coil. The height of the fire chamber HPV-23 is less than that of KGI-56, because the burner of HVV provides better stirring of gas with air, and the gas burns out a shorter flame. A significant number of HSV columns has a heat exchanger consisting of one caner. The walls of the fire chamber in this case were made of steel sheet, the serpent was absent, which made it possible to save copper. The main burner is multi-meter, it consists of 13 sections and a collector interconnected by two screws. Sections are collected in a single integer with the help of tie bolts. The collector has 13 nozzles, each of which is placed gas in its section.
The block crane consists of gas and water parts connected by three screws (Fig. 75). A gas part of a block-crane consists of a housing, valve, crane tubes, a gas crane cap. The case is pressed by the conical liner for the gas crane cork. The valve has a rubber seal along the outer diameter. Top on it presses the conical spring. The saddle of the safety valve is performed in the form of a brass liner pressed into the housing of the gas part. The gas crane has a handle with a limiter, which fixes the opening of the gas supply of PA steam. The crane tube is pressed against the cone's liner with a large spring.
On the crane tube there is an outlet for gas supply to the stall. When the crane is rotated from the extreme left position at an angle of 40 °, the velocity coincides with the gas supply hole, and the gas begins to enter the stall. In order to supply gas to the main burner, you need to press the crane knob and turn on.
The water part consists of lower and upper caps, venturi nozzles, membranes, plates with a rod, ignition retarder, rod gland and clamping rod sleeve. The water is supplied to the water part on the left, enters the subable space, creating pressure in it equal to the pressure of water in the water supply. Having created the pressure under the membrane, water passes through the nozzle of Venturi and rushes to the heat exchanger. Veenturi nozzle is a brass tube, in the narrower part of which four through holes are made, which come out in the outer circular pump. The outlet coincides with through holes that are available in both water part lids. For these holes, the pressure from the narrowest part of the venturi nozzle is transmitted to the above space. The stock of the plate is compacted with a nut, which squeezes the gland from fluoroplastic.
It works automatics by water fluid as follows. When water passes through the nozzle of the Venturi in the narrow part of the highest speed of water and, therefore, the smallest pressure. This pressure is transmitted through through holes into the dummy cavity of the water part. As a result, the pressure difference appears under and over the membrane, which is strung up and pushes a plate with a rod. The rod of the water side, resting in the gas rod of the gas part, raises the valve from the saddle. As a result, the gas pass on the main burner opens. When the flow of water is stopped, the pressure under and over the membrane is aligned. The cone spring presses on the valve and presses it to the saddle, the gas supply to the main burner is stopped.
The solenoid valve (Fig. 76) serves to disable the gas supply during the swelling of the fist.
When you press the solenoid valve button, its rod rests on the valve and moves it from the saddle, while squeezing the spring. At the same time, anchor presses against the electromagnet core. The gas begins to flow into the gas part of the block-crane. After the ignition of the repliment, the flame begins to heat the thermocouple, the end of which is installed in a strictly defined position in relation to the stobnant (Fig.77).
The thermocouple that occurred when thermocouples is heated to wind the electromagnet core. In this case, the core holds anchor, and with it the valve, in the open position. The time for which the thermocouple produces the necessary thermo-emf and the electromagnetic valve begins to hold the anchor, is about 60 seconds. With the swelling, the stamp of the thermocouple cools and ceases to produce the voltage. The core no longer holds the anchor, under the action of the spring the valve closes. The supply of gas and the stall, and the main burner is stopped.
Automatics by traction turns off the gas supply to the main burner and the stall in the violation of the thrust in the chimney, it works on the principle of "gas removal from the stobble". Automation by traction consists of a tee, which is attached to the gas part of the block-crane, tube to the thrust sensor and the sensor itself.
Gas from the tee is served to the stober, and to the thrust sensor installed under the gas travelers. The thrust sensor (Fig. 78) consists of a bimetallic plate and fitting, reinforced with two nuts. The upper nut at the same time is a saddle for a plug, overlapping the outlet from the fitting. A tube supplying gas from a tee is attached to the fittings of the cape nut.
With normal thrust, combustion products go into chimney, without heating the bimetallic plate. The plug is tightly pressed to the saddle, the gas from the sensor does not exit. With violation of thrust in chimney, combustion products are heated by a bimetallic plate. It is strung up and opens the gas outlet out of the fitting. The gas supply to the stall decreases sharply, the flame stops normally heat the thermocouple. It cools and ceases to produce tension. As a result, the electromagnetic valve closes.
The main malfunctions of the WSG-23 column include:
1. The main burner does not light up:
2. When the water intake is stopped, the main burner does not fuck:
3. Disruption of the electrical circuit between the thermocouple and the electromagnet (break or short circuit). The following reasons are possible:
4. Insufficient heating Thermocouple:
