Reviews about geysers Astra

Peculiarities

JSC PKO "Teploobmennik", which produces gas water heaters "Astra", has existed for more than 50 years. Perhaps even our grandparents used his products. True, then this company was called differently.

The column "Astra" is designed to work with hot water. Only gas is used as fuel.

The device of such a column is quite simple and includes several components. The main part - a rectangular case - is mounted on the wall. On the front panel there are windows for ignition and combustion control, a power button, gas supply adjustment knobs. At the bottom there are fittings for supplying gas, hot and cold water, and at the top there is a chimney outlet.

All main nodes are located inside the case and fixed on the rear panel. It also has mounting holes. The combustion chamber is made of high quality refractory material with a long service life.The conciseness of execution is an advantage in the model market and provides the manufacturer with a high demand for their products.

The principle of operation is as follows: in order for gas to enter the gas block and the igniter, it is necessary to turn the pilot burner knob to the left and turn on the device by pressing the button - the burner will turn on sequentially. The temperature of the hot water at the outlet is set by the position of the control knobs. Turning from right to left increases the gas supply, thereby increasing the temperature of the water, and from left to right, on the contrary, it decreases.

The technical characteristics of Astra speakers make it easy to compete with other manufacturers. The main plus is the power of the device: for some models it equals and even exceeds 20 kW. A large combustion chamber and relatively low gas consumption distinguish this brand.

Of course, each model has its own nuances in the characteristics, but you can derive general values. For example, the hot water supply is approximately 10-12 l / min, the outlet water temperature range is 35-60 degrees, the operating pressure range is 0.5-6 bar.

The manufacturer also thought about the safety of their products. If the burner goes out, the water supply will stop.

Specifications column brand HSV 8910-08.02

In order to make the right choice, several models must be considered. Among others, the HSV 8910-08.02 variant is presented on the market, the power of which reaches 18 kW. The design has an open combustion chamber and manual type of ignition. The productivity of this model is slightly less and amounts to 10 l / min. The temperature of the supplied water remains at the same level, but the fuel consumption will be somewhat less and will be 2 m 3 / h.The minimum and maximum operating water pressures remain the same. Connection is carried out with the same parameters. The diameter of the chimney remains the same. The body of the structure has identical parameters.

Repair of a geyser brand "Astra"

Repair of the gas column "Astra" begins with shutting off the gas. The column may or may 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 thing to check is the economizer, it is located behind the electrode. Removing the latter will be quite difficult. It is fixed with 4 bolts. Do not touch the heat exchanger.

When you repair individual components, it is important not to touch the fitting, it is used to measure pressure. If this part is damaged, you will have to change the head

In order to remove the economizer, it is necessary to unscrew only two side bolts. The consumer may well carry out repairs with his own hands. The Astra geyser has contacts in the design that are often contaminated. If they have become unusable, then they need to be replaced. If the economizer does not work after replacement, then it will also have to be changed. These malfunctions are one of the main ones for Astra speakers.

If you encounter a problem when the Astra geyser does not light up, then this may indicate a lack of draft in the ventilation passage. It is very easy to check the tension. The geyser is turned off, and a burning match should be brought to the chimney outlet. If the flame is drawn into the chimney, then everything is in order - you can connect the column. Otherwise, the chimney should be cleaned. However, it is better to entrust this matter to a special master.

The Astra geyser, the malfunctions of which you must consider when operating this equipment, sometimes goes out immediately after ignition. In this case, the supply of cold water to the column should be adjusted. Do not try to dilute hot and cold water as this can cause the flame to go out.

Traction test

It is also worth noting that modern versions of atmospheric speakers often already have automatic security systems (most Astra, Bosh and Vaillant models). They do not allow the launch of the column in the absence of traction, and also turn it off if it disappears during operation.

However, relying on the fact that automation will give you a 100% security guarantee is also not worth it. Therefore, it is necessary to be able to carry out a traction test yourself. For this, professionals use special measuring devices that evaluate the presence and strength of air movement (thrust).

But an ordinary person is unlikely to find such devices at home. Therefore, the usual "grandfather" methods are used:

1. The first method involves removing the front of the device and, taking a small strip of paper, bring 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 event that the flame is drawn into it, this will mean the presence of thrust.

Good to know: fairly common situations when the chimney is working properly, but there is no draft.This may be 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.

Main characteristics

The manufacturer of the columns is the Teploobmennik company. This company has been producing high-tech products for 60 years. The plant produces columns that use only natural gas as fuel, and the output of combustion products is carried out through a chimney.

Modern gas column models are economical, have high efficiency, and do not harm the environment. Apparatuses are more profitable than boilers for heating water, as their performance is higher. They don't use too much fuel, so it's a small amount for the consumer. The average cost of the device is 9000 rubles.

Astra geysers help to solve the issue of hot water supply. Even a model with a low power level is able to heat enough water for the whole family. More advanced devices, which have a capacity of up to 12 liters per minute, are able to simultaneously serve two water connection points.

Despite the fact that this water heater belongs to budget options, it includes elements that ensure complete safety. For example, in some cases the machine will turn off automatically.

This is possible if:

• There is no traction;
• The water supply has stopped;
• There is no flame.

Good technical characteristics and a variety of assortment make columns an ideal option for providing housing with hot water.

Specifics

JSC PKO "Trubny zmeevik", producing gas water heaters "Astra", has been around for more than fifty years. Perhaps even our grandparents used his products. True, then this company was called differently.

The Astra column is necessary for working with hot water supply. Only gas is used as fuel.

The device of such a column is very simple and includes several components. The main part - a rectangular case - is fixed on the wall. On the front panel there are windows for ignition and combustion control, a power button, and gas supply adjustment knobs. At the bottom there are threaded connecting elements from two sides of the gas supply, cold and hot water, and on top there is a section of the chimney pipe.

All key nodes are located in the middle of the case and are fixed on the panel at the back. It also has mounting holes. The firebox is made of good refractory material, containing a long service life. Ease of execution is considered an advantage in the model market and provides the manufacturer with a great demand for their own products.

The working principle is as follows: in order for gas to enter the gas block and the ignition wick, you need to turn the ignition burner handle to the left and turn on the device by pressing the button - the burner will turn on methodically. The temperature of the hot water at the outlet is set by the position of the control knobs. By turning from right to left, the gas supply increases, thus increasing the water temperature, and from left to right, vice versa, it decreases.

By functionality, the components of the column are figuratively divided into water and gas parts. On the market, you can choose repair kits and spare parts for any node separately, as well as the whole node completely.

The technical properties of Astra speakers make it very easy to compete with other manufacturers. The main plus is the power of the device: for certain models it equals and even exceeds 20 kW. A large firebox and relatively low gas consumption perfectly distinguish this brand.

Naturally, any model has its own small details in the characteristics, but you can derive general values. For example, the hot water supply is approximately 10-12 l / min, the outlet water temperature range is 35-60 degrees, the operating pressure range is 0.5-6 bar.

The manufacturer also thought about the safety of their own products. If the burner goes out, the water supply will end.

Each model comes with a data sheet and an operating manual, which details the operating rules and non-hazardous operation, as well as an important diagram of the device.

Now on the market there are a lot of gas-powered columns with an original color palette. Consumers sometimes make a mistake, preferring color to the detriment of technical specifications. The gas column "Astra" does not seek to distinguish itself due to its appearance, but relies on working capacity, has its own range of models.

Model 8910-00.02

has a high power - up to 21 kW and a working capacity of 12 l / min. Dimensions - 700x372x230 mm. The chimney has a diameter of 120 mm. Gas consumption per hour is 2.3 cubic meters. m. Ignition occurs manually.

Firebox of open type. It is not difficult to study thrust. The gas pipe for connection has a cross section of 3-4 inches, the water pipes - 1-2 inches. The weight of the device is 15 kg.

Model 8910-08.02

has a slightly small power (up to 18 kW) and productivity (10 l / min).However, fuel consumption is also lower - 2 cubic meters. m/h The weight of the unit is 14.7 kg. The rest of the device is very similar to the previous model. Ignition is also done manually

Model 8910-15

It has one significant difference - this system with electronic ignition of the burner, which is very comfortable. Now there is no need to worry about the presence of matches.

The power of the unit can reach 20 kW, productivity - 10 liters of hot water per minute. Gas consumption is 2 cubic meters. m/h The column weight is 13.9 kg. The diameter of the chimney is 135 mm.

Model 8910-16

It is also equipped with an electronic burner ignition automatic control system. This automatic device is a champion in power (up to 24 kW). The device heats water at a rate of 12 liters per minute. Gas consumption - 2.3 cubic meters. m/hour. The weight of the device is 14.7 kg.

It should be noted that spare parts for Astra columns can be easily found at inexpensive prices.

Repair and service

The main malfunctions of the HSV-23 column include:

1. The main burner does not light up:

• little water pressure;
• deformation or rupture of the membrane - replace the membrane;
• clogged venturi nozzle - clean the nozzle;
• the stem came off the plate - replace the stem with the plate;
• skew of the gas part in relation to the water part - align with three screws;
• the stem does not move well in the stuffing box - lubricate the stem and check the tightening of the nut. If the nut is loosened more than necessary, water may leak from under the stuffing box.

2. When the water intake is stopped, the main burner does not go out:

• dirt has got under the safety valve - clean the seat and valve;
• weakened cone spring - replace the spring;
• the stem does not move well in the stuffing box - lubricate the stem and check the tightening of the nut. In the presence of an igniter flame, the solenoid valve is not held in the open position:

3. Violation of the electrical circuit between the thermocouple and the electromagnet (open or short circuit). The following reasons are possible:

• lack of contact between the terminals of the thermocouple and the electromagnet - clean the terminals with sandpaper;
• violation of the insulation of the copper wire of the thermocouple and its short circuit with the tube - in this case, the thermocouple is replaced;
• violation of the insulation of the turns of the electromagnet coil, shorting them to each other or to the core - in this case, the valve is replaced;
• violation of the magnetic circuit between the armature and the core of the electromagnet coil due to oxidation, dirt, grease, etc. It is necessary to clean the surfaces with a piece of coarse cloth. Cleaning of surfaces with needle files, sandpaper, etc. is not allowed.

4. Insufficient heating of the thermocouple:

• the working end of the thermocouple is smoky - remove soot from the hot junction of the thermocouple;
• the igniter nozzle is clogged - clean the nozzle;
• the thermocouple is incorrectly set relative to the igniter - install the thermocouple relative to the igniter so as to provide sufficient heating.

Despite the fact that today housing and communal services networks are being modernized everywhere, the quality of the services they provide remains at a low level. This is especially true for hot water supply. To solve this problem once and for all, you should purchase a gas water heater. However, you first need to decide which model suits you better than the others.

Modern manufacturers offer these devices in a wide range. They have certain operational and technical characteristics. Columns can be classified into flow and storage. As for the former, they are smaller, which allows them to be installed even in a small room. Accumulative gas water heaters can hold from 50 to 500 liters of water.

The container in the design has effective thermal insulation, which allows you to keep the high temperature of the water for a long time, this helps to save energy

If you still cannot decide which gas column to choose, then you can pay attention to the equipment under the Astra brand, which will be discussed below. Such devices are good not only because they are manufactured in Russia, which means they have an acceptable cost, but also maintainability

This indicates that in the event of a breakdown with a malfunction, you can deal with it yourself.

Fault Prevention

In order for the water heater to work flawlessly, adhere to the following recommendations:

1. Set the temperature so that hot water does not have to be diluted with cold. The higher the temperature, the faster the heat exchanger is overgrown with scale.
2. If the water is very hard, install a hydromagnetic system in front of the column, which, without any consumables, allows you to remove calcium and magnesium salts.
3. Regularly clean the soot from the chimney and the internal elements of the water heater.
4. It is better to connect an imported modern column equipped with an electronic controller to the mains through a stabilizer. Foreign-made electronics are demanding on the quality of power supply and, with strong voltage drops characteristic of our electrical networks, quickly fail. It is also highly undesirable to turn off such speakers at night.

The owner of the gas column can only be envied: he always has hot water.

Modern water heaters are very convenient, because it is enough to open a tap with water - and the device will turn on automatically, and even adjust the temperature as needed.

But sometimes events develop according to a less favorable scenario: the user, with increasing irritation, tries an icy jet of water with his hand, and the long-awaited sound that the flashing burner makes is not heard.

We will have to postpone hygiene procedures and try to understand why the gas water heater does not light up. This article will help you find and fix the causes of problems.

A gas instantaneous water heater will only work successfully if all of its subsystems are in proper condition. Here is their list:

1. Water circuit: it is simply a pipe of a special configuration (heat exchanger) through which water flows. The main condition for this component is sufficient bandwidth.
2. Gas-burner: will only work if the valve on the gas supply line is open.
3. Ignition system: this is a device that, at the right time, ignites the gas coming from the burner. If it goes wrong, the column, of course, will not be able to turn on. Some ignition systems have a pilot burner (pilot).
4. Smoke exhaust system: there should be no insurmountable obstacles on the path of the combustion products from the burner itself to the atmosphere. The main part of this system is not a column component - it is a vertical or horizontal chimney that faces the street.
5. Automation: this system includes a whole set of devices and sensors, and all of them control the operation of the gas valve.

Automation can be mechanical ...:

• membrane installed in the water circuit and connected to the gas valve. Responds to changes in water pressure;
• bimetallic plate. If the pilot burner suddenly goes out, the plate will cool down and shut off the gas supply.

... and electronic:

• draft sensor: blocks the gas supply if there is a risk of combustion products entering the room;
• flame sensor installed in columns without a pilot burner: it is triggered when the main burner goes out;
• overheating sensor.

Violations in the operation of any of the listed systems manifest themselves as follows:

• the burner does not ignite at all;
• the flame flares up, but immediately goes out (the gas column ignites and goes out);
• fails to ignite the igniter.

Let us consider in more detail the reasons causing such phenomena.

Gas equipment is a device of increased danger, therefore, according to the regulations, it is carried out by the gas service. See our website for basic installation requirements.

Let's consider the principle of operation of the pressure switch for a hydraulic accumulator. And also we will analyze the order of adjustment.

Power, ignition system, security system are important criteria to consider when choosing a geyser. This topic provides a detailed overview on the choice of gas equipment.

Basic Rules

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

The same applies to operation. Therefore, they are subject to the same handling rules as 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 concentration of gas, it is necessary to open the windows and ventilate the room.
3. Until the house / apartment is completely ventilated, you can not use any electrical appliances or light a fire.
4. After that, you need to call the gas service.

It's important to know:
only certified specialists can carry out installation, as well as connection, in accordance with the design documentation approved by the gas industry. Most often, the user manual comes with the device itself. So, if you have an open-type geyser installed, then:

So, if you have an open-type geyser installed, then:

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

1. Do not start a fire in the burner and use it in the event of a back draft in the chimney or none at all.
2. Without having previously studied the instructions, it is forbidden to turn on the device or set fire to the gas using the “scientific poke” method.
3. In the room where such a unit was installed, there must be a constant flow of air.
4. It is strictly forbidden to make any changes to the design of the gas column.
5. To prevent burns, avoid touching the parts of the front panel located next to the viewing slot, as well as the elements of the chimney.

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

Peculiarities

JSC PKO "Teploobmennik", which produces gas water heaters "Astra", has existed for more than 50 years. Perhaps even our grandparents used his products. True, then this company was called differently.

The column "Astra" is designed to work with hot water. Only gas is used as fuel.

The manufacturer also thought about the safety of their products. If the burner goes out, the water supply will stop.

Currently, there are many geysers with unusual colors on the market. Consumers sometimes make the mistake of choosing color over performance. The Astra geyser does not seek to stand out due to its appearance, but relies on performance, has its own model range.

Model 8910-00.02

has a high power - up to 21 kW and a capacity of 12 l / min. Dimensions - 700x372x230 mm. The chimney has a diameter of 120 mm. Gas consumption per hour is 2.3 cubic meters. m. Ignition occurs manually.

Open type combustion chamber. Traction is easy to check. The gas connection pipe is 3⁄4 inches, the water pipes are 1⁄2 inches. The weight of the device is 15 kg.

Model 8910-08.02

has a slightly lower power (up to 18 kW) and productivity (10 l / min). However, fuel consumption is also lower - 2 cubic meters. m/h The weight of the unit is 14.7 kg. The rest of the device is very similar to the previous model. Ignition is also done manually

It should be noted that spare parts for Astra speakers can be easily found at reasonable prices.

Conclusion

If you still do not know whether it is worth buying an Astra gas water heater, then you should consider its features in more detail. For example, the copper heat exchanger in all models has an increased wall thickness. This ensures good heat transfer from heated gases to water, which allows saving. For more convenient operation, the manufacturer has equipped the design with a display with which you can determine the temperature of the heated water.

Install instantaneous water heaters began in times of lack of hot water. Old-style models are still found in some "Stalinka" and "Khrushchev". However, residents of modern houses do not refuse to install heating equipment, which is associated with seasonal shutdowns.

It should only be taken into account that the models of the old and new samples differ somewhat in the type of control. How to use a gas column correctly? If you have any difficulties with this, then our article will help to solve them.

It is easier to remember the rules for using the device when you understand its device. Regardless of the manufacturer, all geysers - "Neva
”,“ ”and others - have the same design. Only the location of the nodes can change.

Main knots:

• Heat exchanger;
• Collector for removal of gases;
• Ignition block;
• Burner;
• Water and gas fittings.

Facing the column is made in the form of a metal casing - in some models it has a viewing window. On the panel there are regulators of power and temperature. Electronic control is complemented by a display.

Ignition block. Depending on the type of ignition, the product has
Piezo ignition or electronic battery activation button.

• semi-automatic models. Piezo ignition can be started in different ways. In some cases, you need to hold the button and press the power regulator. The wick will burn until you turn off the device yourself. It is recommended to turn off the burner after use or when leaving the house. So you can save gas and extend the life of the device.
• Automatic equipment is more expensive, but it is economical in operation. The wick does not burn constantly. The burner ignites only when the mixer is opened and goes out when it is closed. The electric charge is sent by batteries or a turbine. Batteries need to be changed periodically, and for the normal operation of the turbine, it is necessary to ensure stable pressure in the line.

Outlet manifold. Situated at the top. Pipes are connected to the branch pipe for the removal of combustion products to the street. In devices with a closed combustion chamber, the collector is located below and is equipped with a fan for forced removal of burning. These are turbocharged models such as Neva Turbo, Neva Lux 8224, Bosch WTD.

Columns of the trademark "Astra" and "" are produced only with an open combustion chamber.

Heat exchanger (radiator) is the main part in the water heater. Water flows through its tubes, which is heated by a burner. A high-quality radiator is made of pure copper. If impurities are added to the alloy, then the knot quickly burns out and leaks. Read the article "" to learn more about his device.

Burner located under the radiator. A reliable body must be made of steel. The part distributes the flame through the nozzles for uniform heating of the heat exchanger.

gas node may be on top of the water (in older models) or to the right of it. Operation is controlled by turning the gas on and off.

water block located nearby, thanks to it fuel enters the system. When water is started, pressure is created in the system, which causes the rubber membrane to bend. She pushes the stem, which turns the fuel valve.

An ignition device is located near the burner. Also, the equipment is equipped with protection sensors:

• The draft sensor monitors the presence of draft in the system;
• Ionization sensor - control of the presence of a flame;
• Thermostat - temperature measurement, protection against overheating over 90 degrees.

When one of the sensors is triggered, the device turns off.
