Boiler "Zhitomir" - technical characteristics, owner reviews

Heating equipment of the Zhytomyr brand “Atem” is widely known in the countries of the former USSR. The plant's products are famous for their reliability, simplicity and affordable price tags. Let us highlight another important advantage - the manufacturer is as honest as possible with the buyer. The documentation for the Zhitomir solid fuel or gas boiler reflects the real operating parameters of the equipment, no overestimation of efficiency or other marketing techniques.

We decided to collect all the heat generators of the Atem model range in one publication and make a detailed review of each line of boilers. The task is to lay out the technical characteristics, identify the strengths and weaknesses of the units. At the end we will attach reviews from owners who use this equipment for heating private houses and apartments.

General information

The modern gas heating boiler ATEM Zhytomyr has high performance and compact dimensions. The use of foreign automation allows us to achieve optimal performance.

The user has access to many settings, which allows him to maintain the desired temperature in the room. Sensors will ensure that everything works without interruption. Consumers love Zhytomyr boilers, and reviews emphasize the optimal price-quality ratio.

Advice! The cost of a Zhitomir boiler today is 12-45 thousand rubles. Moreover, products at the upper price range have high performance and are capable of heating large areas of premises, suitable for heating multi-storey private houses. For heating a small house or apartment, a modification in the middle price range, up to 20,000 rubles, is suitable.

The lineup

The company produces two types of gas heating boilers:

• floor,
• parapet.

Floor standing boilers

In turn, a floor heater is divided into:

1. single-circuit,
2. double-circuit.

A single-circuit floor-standing gas boiler only powers the heating system. It is extremely economical, thanks to the use of imported automation, which switches the system to energy saving mode as soon as the installation reaches the set temperature.

And at the moment when the temperature drops below a predetermined level, the single-circuit unit lights up at full strength. High-quality components allow you to withstand multiple on/off cycles throughout the heating season.

If you need to not only heat the premises, but also get hot water, you should buy not a single-circuit, but a double-circuit boiler Zhitomir. It has a higher cost, but can perform two options at the same time.

To connect the device, you will need to connect two additional pipes. In the product, the heating circuit operates independently of the hot water preparation circuit.

Advice! Choose a single-circuit boiler if you already have hot water supply. This will save money, because models with one circuit are much cheaper.

When choosing a floor-standing boiler in Zhytomyr, you should pay attention to the technical characteristics. So, all floor-standing models have:

• Efficiency 92%,
• maximum coolant temperature 90 °C,
• minimum operating gas pressure 635 Pa.

Moreover, each specific model has:

• power, ranging from 7 to 60 kW.
• the amount of coolant in the boiler ranges from 14 to 70 liters.
• natural gas is consumed in the range of 0.76 - 6.8 cubic meters per hour.
• If we consider a double-circuit floor-standing boiler, then its DHW capacity is in the range of 175 - 1400 l/s.

Wall boilers

Just like a floor-standing boiler, a hanging boiler can have one or two circuits. The entire model range has the same efficiency characteristics, maximum coolant temperature and minimum operating gas pressure - 90%, 90 °C, 635 Pa, respectively:

• The power range of wall-mounted boilers is from 5 to 15 kW.
• The amount of coolant in the boiler is from 5 to 17.5 liters.
• natural gas is consumed in the range of 0.56-1.67 cubic meters per hour, depending on the specific model.
• The suspended double-circuit boiler has a capacity for the hot water preparation circuit ranging from 160 to 345 l/h.

As you can see, the wall-hung and floor-mounted single-circuit boiler Zhitomir can operate in conditions where the gas in the mains has low pressure. The disadvantages of the products of the brand in question include the low permissible coolant pressure in the heat exchanger:

1. floor-standing versions have an indicator of up to two kgf/m2,
2. wall-mounted – up to zero point seven kgf/m2.

For comparison, foreign boiler models can operate with pressures of up to three kgf/m2. This indicates that Zhitomir gas units are more suitable for independent heating systems of a small house, the number of which is no more than two.

Varieties

Today, several types are involved in the production of Zhytomyr boilers - parapet (wall-mounted) and floor-mounted. In turn, floor products also have divisions into single-circuit and double-circuit.

Floor-standing

If a gas boiler is needed only for heating purposes, attention should be paid to single-circuit models. They are unpretentious, practical and economical. The equipment of the single-circuit boiler “Zhitomir” primarily involves imported components. Thanks to them, the device can be turned on and off if necessary. And if there is a need, in addition to heating, to have hot water in direct access, you will need to choose from dual-circuit options.

Due to price demand, double-circuit boilers are a little more expensive, but they also provide double pleasure to the consumer in their operation.

In terms of their technical characteristics, floor-standing boilers mostly have the following similarities:

• the maximum temperature limit is +90 degrees;
• efficiency is 92%;
• gas pressure – 635 Pa.

But when choosing a model you definitely like, you need to consider its specific characteristics and capabilities.

Wall mounted

The same separation as in floor-standing boilers is also present in wall-mounted boiler models. They can also be single-circuit or double-circuit. The efficiency of all devices is the same. The same applies to gas pressure.

But it’s still worth considering their characteristics in more detail:

• the power of parapet boilers must be no less than 5 kW and no more than 20 kW;
• the coolant in the device is no more than 17.5 liters;
• depending on the chosen model, natural gas consumption is considered; according to the standard - 0.56–1.67 cubic meters per hour;
• profitability due to imported automation.

For its part, the manufacturer provides a wide range of boilers to choose from, but the Zhitomir-3 KS-G-020 SN model is still in great demand. This device differs from its counterparts not only in terms of availability in terms of price, but also has clear technical data. The design of the device is designed in a minimalist style; the appearance of the boiler looks like a cabinet. It should only be placed on the floor. On the front of the model there is a small door behind which hides a button for turning on and adjusting the device settings. In the same part there is a control window, with the help of which you need to monitor the performance indicators of the boiler.

The basic package includes a housing, which also includes heat exchanger elements. On the outside, it is covered with heat-insulating material and a casing made of steel. The burners are presented in two pieces: one is the main one, and the second is the ignition one. The package includes a gas duct and an automatic gas valve, which is responsible for safety during operation.

If the temperature rises above +95 degrees, the shutdown sensor breaks the circuit to the valve, and the valve itself automatically closes the gas supply.

Range of gas parapet boilers

The parapet-type gas boiler “Zhytomyr” is an inexpensive device for organizing water heating of a small country house with an area of ​​up to 150 m². It successfully combines elements of turbocharged and atmospheric boilers - a closed combustion chamber and a coaxial chimney in the absence of a blower fan.

The movement of gases through the coaxial chimney of a parapet heat generator occurs naturally, without a fan or smoke exhauster

Principle of operation. The heat generator, suspended from the wall near the floor, burns natural or liquefied gas without pressurization. Combustion products are thrown out through an internal short pipe passing through the wall. Air enters the firebox through the external channel (outer pipe) naturally. New versions are equipped with 2 separate pipes - smoke and air.

The line of parapet models "Zhitomir-M" includes 5 single-circuit and 4 double-circuit boilers, designated by the abbreviation AOGV-SN and ADGV-SN, respectively. Thermal power of the devices is 5, 7, 10 and 15 kW. Let's reveal the design features of heaters:

• the material of the main heat exchanger is steel, the secondary heat exchanger for hot water supply is copper;
• combustion chamber – completely closed;
• burner - tubular type, safety automatic - gas valve SIT 630 made in Italy;
• ignition – piezoelectric, from a button on the valve;
• 4 fittings DN40 for connecting the heating system - two on each side of the housing.

The boiler comes complete with a gas-air unit (otherwise known as a coaxial pipe), a flexible pipe for connecting to the gas main, fasteners and an asbestos sealing cord. The cost of a single-circuit unit with a power of 5 kW (heated area - 50 m²) is 270 USD. e., double-circuit 15 kW - 475 USD. e.

New version of wall heat generator with separate pipes for air and flue gases

Reference. Up-to-date information on the pricing policy and offered models of heat generators can be found on the official resource at: shop.atem.ua.

Specifications

The Zhitomir-M parapet boiler has the following operational parameters:

• fuel efficiency (EF) – 90%;
• minimum inlet gas pressure – 6.4 mbar, maximum – 17.6 mbar;
• operating pressure in the heating system – 1.5 Bar, maximum permissible – 2 Bar;
• coolant temperature at the outlet of the heat exchanger – no more than 90 degrees;
• the amount of water in the boiler jacket is from 5 to 19 liters;
• maximum pressure from the cold water supply – 6 Bar;
• The dimensions of the largest device in the line are 360 ​​x 495 x 825 mm (LxWxH).

Combined models

In addition to traditional heating equipment, it produces 3 combined series of boilers:

1. Electric gas heat generators KS-G-SN / KE with a heat output of 10-12 kW.
2. Units "Zhytomyr-9" burning coal and natural gas. Designation - KS-G-SN / AOTV, power - 10, 12 and 15 kW.
3. Heating and hot water installation “two in one” KS-G-SN, otherwise – “Zhitomir-10”. The range of models covers the range of 7…30 kW.

Clarification. All types of combination boilers are produced in a floor-standing version.

The line of gas-electric boilers is built on the basis of Zhytomyr-3 units and does not differ in appearance from conventional floor-standing units. The design is complemented by a control unit and an electric heater placed inside the water jacket. 2 types of heating elements are installed - with a power of 4.5 and 9 kW. Important feature: both heating methods can be turned on one by one or simultaneously.

Electric-gas (left) and coal-gas (right) boiler

The coal-gas heat generator “Zhytomyr-9” has the following parameters:

• on the left side of the body there is a firebox with a volume of 47 or 70 liters for storing anthracite or firewood;
• to the right of the solid fuel chamber there is a gas firebox with a Polidoro burner and an SIT 630 automation unit, a common heat exchanger, and separate smoke exhausts;
• efficiency on gas – 92%, solid fuel – 78%, operating water pressure – 1 Bar (Max 1.5 Bar);
• work in a closed system is allowed, condition - installation of a safety group with a 1.5 bar safety valve;
• duration of 1 coal combustion cycle – 6…8 hours;
• There are modifications with a DHW water circuit.

Comment. When operating on coal and wood, the boiler produces less heat than on gas, which is noticeable in terms of efficiency. Example: the KS-G-016SN / AOTV-12 unit in the first case develops a power of 12 kW, in the second - 16 kW.

The operating algorithm is simple: while the coolant is heated by coal, the gas burner does not ignite. When the sensor detects a drop in temperature, the gas supply will open and the right side of the heat generator will start working. The main thing is that the pilot light is lit.

The gas installation “Zhytomyr-10” consists of two separate sections - a boiler furnace and an instantaneous water heater. Burners, safety devices and heat exchangers are completely separated. In fact, the gas water heater and the boiler are combined in one housing. The goal is to increase water consumption for hot water supply to a comfortable level without compromising heating efficiency.

Rules for filling the system with water before turning on the gas boiler

Before lighting a gas boiler and turning on the heating system, it is first filled with cold coolant, which, after heating, will circulate through the pipes and radiators. During the first launch, everything is carefully checked so that further operation is uninterrupted and the equipment does not require repairs.

The unit body has a special tap located near the pipe to supply coolant to the system. During the filling process, the pressure in the system is monitored thanks to the presence of sensors and pressure gauges. In modern boilers they are already installed and there is no need to purchase them additionally. When the device is filled with water, the mark on the sensor rises. When it reaches the 1.5-2 atmosphere mark, the water supply is shut off and thus completing the filling.

These pressure parameters can be changed as they depend on the manufacturer's requirements for the operating pressure in the heating system. But filling with cold water does not end there, since replenishment will be required after the structure is freed from air pockets.

Pre-launch process

The sequence of actions to prepare for startup depends on the type of gas boiler being installed. It can be single-circuit or double-circuit, with a closed or open combustion chamber, floor-mounted or wall-mounted. The first launch is always associated with an increased level of responsibility and risk, so it must be carried out in compliance with all the nuances and subtleties.

The instructions for the gas boiler contain simple explanations according to which you need to start a specific model. The gas boiler must by this time be connected to communications in accordance with the agreed project. The first start-up is carried out after connecting the heating system into a single whole and installing equipment, radiators, and pipes.

Gas boilers with a closed combustion chamber do not require a large chimney. Also, their positive characteristic is the ability to be located close to the wall with a gap of 2 cm, which allows you to save space in the apartment

According to fire safety rules, the gas boiler should be located in places protected from the possibility of ignition, away from flammable objects and materials. In this case, the heating unit should be located at a certain distance from the wall and floor. The exact distance value is individual for each boiler and is indicated in the instructions.

Wall-mounted models are hung on anchors so that there is a small gap between them and the plane of the wall. The boiler must be installed strictly exactly at the water level. Distortions and tilts of the equipment are unacceptable.

After installing the gas boiler to the wall, it is necessary to connect the device to the pipe supplying cold water. To do this, you need to remove the plugs from the receiving pipes.

In addition, a coarse water filter and a mud filter are installed at the inlet of communications to the boiler, which will protect the internal pipeline of the unit from clogging and sedimentation. Ball valves are installed on all pipes when piping.

Installing and running pipes to the boiler is an important task. The end result should not only be beautiful and aesthetically pleasing, but also provide easy access to key parts of the system

Before starting the boiler, an important step is to install a gas pipe to it. This work cannot be carried out independently. You will have to invite craftsmen from the GorGaz branch with which you have a service agreement.

Gas workers will calculate the required length of the pipe, lay it, install a gas meter and seal it. In order for the device to work for a long time and not smoke, you need to take care of the supply of good gas.

Also, for a gas boiler, for safety reasons, it is advisable to install a separate power line with its own automatic circuit breaker installed at the entrance. A socket should be placed close to the device, at a distance of 30-50 cm from the body. Grounding must be done; it will protect users from receiving electric shocks in the event of a breakdown on the housing.

Reliable and high-quality pipes are the key to the longevity of the heating system. You should buy pipes and radiators only from trusted manufacturers. A cheap product in this case will only bring problems

A boiler installed in a private house is equipped with its own chimney. It should go outside through the wall or through the attic space to the street. The chimneys of boilers in city houses up to five floors are connected to a public smoke shaft.

Depending on the specific device, the amount of work required to install the chimney varies. Some devices with a closed chamber are also equipped with a pipe to supply air to the combustion zone.

Upon completion of all preparatory work, you need to fill the heating system and the boiler itself with cold tap water. After filling, the system is checked for leaks. Then a remote control panel and a thermostat are mounted on the wall, to which temperature sensors are connected.

Features of filling the system with water

Before you ignite the gas boiler and activate the system, you need to properly fill the heating system and all its elements with water. To begin filling the heating equipment and the circuit connected to it with water, first disconnect the boiler from the power supply. We still need to turn off the gas supply.

Next, you need to turn on the water by opening the valve or tap that supplies cold water, as well as the make-up tap located at the bottom of the boiler. The exact location of the make-up tap is indicated in the instructions for the device.

The technician checking the system must definitely go around all the rooms along the pipes and radiators and check them for the presence of water leaks. If a leak is detected, you need to shut off the water supply and begin to fix the problem.

Before filling the system with water, you need to make an additional bypass of all heating devices and make sure that all connections are tight and tight.

You can drain the water from the system completely or shut off the corresponding link. Then you need to unscrew the leaking pipe connection, drain the water or screw in the plug. Afterwards, the necessary material and tools are prepared, the plugs are unscrewed, and the pipe is tightly reconnected to the radiator using sealant. Next, you need to check the tightness of the system again.

The intake of water is accompanied by a characteristic sound. It is important to unscrew the valve slowly and gradually, avoiding sudden movements. If you open the tap suddenly, there is a high probability of air pockets occurring. Simultaneously with the system being filled with water, the gas boiler pressure gauge shows the current pressure in the system.

The operating pressure must be found in the instructions for using the boiler. When the pressure reaches the operating range, you need to stop the water supply by closing the valve. Typically, the operating range of the boiler is a pressure value of 1.5 - 2 atmospheres.

It is recommended to fill the system with water in the warm season. If the temperature outside is sub-zero, you should preheat the room using a portable radiator to about 20 degrees Celsius.

Removing air pockets

Upon completion of the filling stage, the system must be checked for air pockets, excess air must be bled off and, if necessary, cold water must be added. If you do not bleed off excess air, the radiators will not heat up enough, since there will be a space in them that is not filled with heated coolant.

The Mayevsky tap is a simple device that is a needle valve. It is used to bleed air from the batteries.

To make the first start successful, you should go around each radiator with a screwdriver or other tool and bleed the air from the heating devices. Some batteries are equipped for this procedure with an air vent, a Mayevsky valve, which can be controlled by hand.

The air from the pipe system and the heating devices connected to it is drained until water flows. While the air flows, a characteristic hissing sound is made.

For convenience, it is worth preparing in advance a basin or ladle into which the water will be drained, as well as a rag, which is then carefully used to cover the stream of water so as not to stain the wall or nearby appliances. After the air has been released, you need to tighten the radiators tightly so that water does not leak from them.

Modern boilers are equipped with devices that allow you to automatically remove air pockets from the heating system. However, such devices do not always effectively cope with the task assigned to them. Therefore, you often have to bleed the air manually.

Having completed bleeding the air from the closed heating circuit, they begin to fill the space freed from air pockets with water. Without this operation there will be no working pressure in the system, because it is not filled enough.

To replenish the circuit with water, connect the unit to the power supply, open the feed tap and press the “Power” button. In this case, the pump should start and the boiler burner will try to ignite. However, after a couple of seconds, the electronics will block all attempts, and the display will display an error code, because gas does not flow to the injectors.

This procedure will need to be repeated several times. It will be necessary to recharge until all the air comes out of the pipes and devices of the boiler, as well as the circuit connected to it. When the stage of filling the system and freeing it from air pockets is completed, you need to check the pressure and open the gas supply.

The circulation pump ensures the movement of the coolant. The manufacturer is prohibited from performing any manipulations with it independently, otherwise the warranty obligations automatically become void. If the pump breaks down, simply replace it

Before igniting the boiler, the gas engineer carefully checks that the connection diagram corresponds to the design solution on the basis of which it was assembled. The technician once again makes sure that the pressure in the system corresponds to the parameters recommended by the manufacturer. Tests the tightness of all communication lines and their connection points.

Checking and flushing the system

In order to ensure the high quality of the work performed and prevent possible water leaks, plumbers recommend performing a pressure test of the system before starting the boiler. This procedure will require expensive equipment - a pressure pump. However, there is no need to buy it, as it will only be needed for half an hour to check the system.

You can borrow such a device from friends or rent it. You can also use the service of an on-call technician who will independently check the system and correct any problems that have arisen if necessary.

The purpose of pressure testing is to identify leaky areas of the system and eliminate them. A system that has gone through this process is guaranteed to serve for a long time and will not fail at the most inopportune moment.

There are two methods of crimping: with a water column or with compressed air. The essence of the procedure is pumping air or water into the system to establish a pressure level in it approximately one and a half times higher than the working one. After pumping, it is necessary to record the pressure value on the pressure gauge and wait 10 - 15 minutes.

Before performing pressure testing, it is important to take into account the characteristics of all elements that make up the heating system. In addition to checking the functionality of the system, it is also important not to damage its structural elements with excessively high pressure.

If at the end of this period of time the pressure remains at the same level, then the system is considered pressurized and has no leaks. If the pressure has dropped, then you need to identify the place where water is leaking and eliminate this problem. Then carry out the procedure again.

Please note that before installing a new unit, flushing a circuit that has been in operation for several years must be done. All manufacturers of gas equipment warn that installing a gas boiler in an old circuit that has not been cleared of mineral deposits is prohibited. Failure to comply with the rule will result in the boiler owner losing his warranty.

This process is carried out in two stages. Initially, rough washing is carried out. In this way, the largest contaminants are removed. The pressure in the system when flushing should be about 3.5 atmospheres. After the water is agitated under pressure, it is released from the system through a drain valve.

In this case, the coarse filter often becomes clogged. It may need to be washed once or twice. Finish washing is carried out using pressure pumps.

After finishing washing, you need to check the coarse filter. It must be uncontaminated. Supplying contaminated water to the boiler is highly undesirable

After completing the preparatory work, you can start launching the device.

How to start a gas boiler for the first time

What is the reason? Won't it be torn apart? The unit is not leveled correctly or the heating system is clogged. The device has nothing to do with it. A floor-standing boiler Zhitomir 3 Atem KS-GV SN 12.5 kW, Eurosit was installed, after 8 years of operation it stopped turning off when heated and began to work continuously, raising the temperature to over 80 degrees. You have a problem with the automation, that is, the thermostat does not work, you will have to change the automation completely. I turn on the new Zhitomir parapet boiler.

Everything is working. I turned it on in the evening, everything worked until night.

We woke up in the morning and the boiler had gone out. And already three times. Before this, they turned it on once, everything was fine, and then it got warmer, and they turned it off, and the second time there were such problems. There is a craving. He worked for at least exactly three hours.

You most likely have oxidation of the draft sensor; it does not see the contact and because of this it quickly goes out. You need to clean the connections until they are shiny and the boiler is working. It began to go out at low and medium throttle. From 1 to 5 it will work and the gas supply will be turned off. It works fine on 6 and 7. The second season has worked, the circulation pump is installed. It even happened that the igniter did not light up, cleaned the terminals, worked normally for about a day and began to turn off again. In principle, it’s already spring and I don’t want to call an unfamiliar gas worker.

Yes, maybe I can figure it out on my own. Can anyone tell me what the problem might be and its solution? The igniter flame - the root third is bluish, the middle and top are yellow, fluctuates quite strongly. In general, in the fall there was a strange symptom: if you turn on the igniter and immediately turn on the burner, the gas supply turns off after a minute or two. And if the igniter burns for five minutes, the gas supply does not turn off.

We had a similar situation. During assembly, the thermal breaker was not completely screwed into the magnetic valve. Apparently the contact between them was not initially the strongest, and over the two seasons of work the contact worsened. And apparently, there was not enough contact, but there was enough. We tightened it a little more and everything became normal. I had the following problem: the Zhitomir-M parapet gas boiler, installed last year, began to go out. The most interesting thing is that it goes out in position 2 and 1 in position 3 lights up without problems.

This happened just yesterday, before that everything was normal.

User manual

Before starting to use the Zhytomyr equipment, it is necessary to carry out high-quality installation of the product and check the pipes, especially if the boiler is a double-circuit boiler.
Next, the first launch is made. And after that the boiler enters the standard operating process. According to the standard scheme, you need to turn on the device, light the wick, then adjust the heat supply. After these manipulations, you can change the settings to reduce heating or, conversely, increase it. At the end of the cold season, the boiler must be turned off for the warm period, since it is not needed, which will eliminate unnecessary waste of the device’s potential. In some cases, after a warm period during connection, it is not possible to light the boiler, the igniter goes out. This may be due to weakened draft, weak gas pressure, or a malfunction of the valve responsible for the gas supply.

It is very rare that the gas valve fails to start during use. The reasons for this may be broken contacts, poor quality of the pilot burner, or an incorrectly installed thermocouple. Troubleshooting is simple - you just need to check the contacts

It is necessary to pay attention to the height of the flame. It should be at least 2.5 cm. You can try to reinstall the thermocouple or replace it altogether

Then check and light the boiler the first time

You can try to reinstall the thermocouple or replace it altogether. Then check and light the boiler the first time.

As for the model range of Zhytomyr boilers, in general you can hear only positive reviews. Ideal heating and the ability to regulate the temperature allow you to feel comfortable throughout all the cold weather. A fairly simple mechanism for turning on and setting - just a few knobs and pointers that tell you what needs to be done.

In addition, Zhitomir boilers have a protection system against lack of draft in the chimney system, as well as protection against overheating of the device. In all cases, the gas supply is shut off, which is a big difference in the troubleshooting process. Otherwise, Zhytomyr gas boilers are a shining example of quality and reliability. They are in great demand on the world market. The technical characteristics of Zhitomir boilers allow connection to be made in almost any designated place. Boilers “Zhitomir” are, first of all, a concern with which you can forget about the costs of heating your home using electric radiators, as well as excellent quality at an affordable price.

A review of the Zhitomir gas boiler is in the next video.

Malfunctions

Let's consider possible malfunctions of Zhitomir gas boilers that may appear during use, and options for solving them.

All problems with gas communications and the gas boiler valve must be repaired only by authorized specialists.

Disruption of water movement

If the circulation of water is difficult or there is no water at all in the heating system, the reason may lie in:

• insufficient amount of fluid in the system;
• presence of air in the heating system;
• water leakage from the heating system;
• significant scale deposits.

You can resolve this issue by taking the following steps:

1. Refill the heating system with water.
2. Release the air by filling the heating system with coolant from below.
3. Detect and repair fluid leaks.
4. Clean and flush the system.

Reduced heating efficiency and increased gas consumption

If such a problem occurs, the reason is most likely the following:

• the heating system is installed incorrectly;
• Too much scale has been deposited.

To get the system working, you need to:

1. Correctly install the heating system.
2. Clean and flush the boiler.

Condensation forms

If drops of water form and flow onto the main burner, then most likely the reason is the low temperature of the coolant. To eliminate this problem, you need to warm up the boiler.

The burner goes out

The Zhitomir gas boiler does not ignite, which means the possible reasons are:

• weak heating of the thermocouple;
• low gas pressure in the system;
• damage to the safety automatics or gas valve;
• loosening of the thermocouple.

This malfunction can only be resolved by calling a gas service specialist.

Cotton when igniting

If a pop is heard when the boiler is ignited, then most likely this indicates a poor fire connection between the ignition and main burners. Gas pressure is too low.

In this case, only a specialist will help.

Burner extinction

If the Zhitomir gas boiler goes out, both the main and pilot burners, then the reason is poor draft. How to fix this problem? Insulate the chimney and remove air suction.

These are the main reasons why malfunctions may occur with a domestic unit.

Currently, Atem Zhitomir gas boilers are sales leaders in their position. Excellent technical parameters, excellent quality and budget price make the brand’s products very popular. Having decided to purchase a Zhytomyr unit, the buyer will be satisfied with the purchase. Because such equipment will make it possible to organize reliable and stable heating of the house.

About the manufacturer and its products

The Atem brand and its Zhytomyr gas boilers have been known and available to customers for more than 27 years. Of course, from the beginning of production to the present time, the products have changed a lot. The company's developers are constantly improving units to satisfy all the needs and wishes of consumers. That is why Atem is a leader in the field of heating equipment in the domestic market.

Good quality and reliability are the main parameters related to boilers of this brand.

Atem products have received various awards more than once. For example, “European quality”, “Golden Mark”. The units are marked with the “Highest Standard” quality mark.

Gas boilers Atem Zhytomyr are designed for houses equipped with chimneys. The product range is quite wide, and this gives the potential buyer the opportunity to choose the optimal model.

Design Features

The main elements of the Zhitomir boiler are:

• a housing in which the main components and equipment are installed;
• gas burner unit located in the firebox. Here gas combustion occurs and heat flow is released;
• recuperative heat exchanger, in which heat exchange occurs between combustion products and coolant;
• gas exhaust system, its responsibilities include removing combustion products outside the boiler and releasing them into the chimney.

Construction of the Zhitomir boiler In order to increase the efficiency of heat transfer, the gas boiler Atem Zhitomir 3 has the following design features.

1. The heat exchanger pipes made of heat-resistant steel have a rectangular cross-section; this device allows you to increase the contact area of ​​the flue gas and the coolant.
2. The counter movement of coolants was organized, this solution made it possible to increase the efficiency of the heat exchange device to 92%;
3. To increase the area of ​​interaction between combustion products and the coolant, as well as to prevent the accumulation of soot on the surface of the steel pipes of the ATEM boiler heat exchanger, turbulators are installed. Soot accumulates on the lower surface of the turbolizers, while the pipe walls remain clean. To remove soot, you need to periodically remove the turbolizers and clean them of soot.
4. Gas double-circuit turbocharged boilers in Zhitomir have a coil of copper pipelines around the heat exchange heating pipes.

Double-circuit gas unit Zhytomyr Atem To organize a stable gas combustion process, a POLIDORO gas burner device is used. Its distinctive feature is a single-stage atmospheric burner. The edges of the burners themselves are made of heat-resistant steel, which allows you to maintain the combustion mode at different gas supplies to the firebox. Even at low gas consumption, the heating of the edges is sufficient to maintain stable combustion.

Circulation pump

The boiler circulation pump requires special attention during startup.

Air often accumulates in it, and its blades sometimes seem to get stuck (the boiler will display a corresponding error).

It is recommended to rotate the shaft manually before starting.

To do this, you need to remove the front panel of the housing, unscrew the central bolt on the pump and use a straight-bladed screwdriver to turn the shaft in the direction indicated by the arrow.

An air vent is installed above the pump. You need to pull the bright lid and let the air escape.

Conclusion

At first, the system may make gurgling sounds, all because during startup it is impossible to bleed air down to the last atom. It will gradually be removed through the expansion tank valve. Periodically check the pressure on the pressure gauge - it should be within the operating range. Temperature adjustment and other boiler settings are described in the instructions for each model.

How much does a gas boiler cost in Zhytomyr?

If you look at the reviews of the Zhitomir gas boiler, it becomes obvious that many users are attracted by the optimal combination of quality and cost. At the moment, the price of the Zhitomir boiler is in the range from 12,000 to 45,000 rubles. And the higher the cost, the correspondingly higher the performance, which means the equipment is able to heat a larger area. The product of this company is ideal for heating private multi-storey residential premises. If you need to heat a small house, then a boiler will be sufficient, the cost of which is up to 20,000 rubles. Thus, prices for gas boilers in Zhytomyr are quite reasonable.

Specifics

The ATEM brand has invested all its efforts in the development and production of a good device for individual heating. For more than 27 years, the company has been providing heat to its own consumers in the form of Zhytomyr gas water heaters. Since the inception of the first boiler, a very large rebranding has been carried out, the device has received changes from the internal base of spare parts to the external design. Nowadays, the Zhitomir

"is a neat, small-sized block with switching instructions that even a child can handle. The main quality characteristic of boilers of this brand is the reliability and quality of the device. The technical properties of products have also changed with the emergence of recent technologies. Not only these components, but also other facts made it possible for the ATEM brand to acquire the “European Quality Level” award.

But the company did not stop there either; Zhitomir boilers received the “Golden Mark” and “Highest Standard” awards, proving to everyone that they occupy first place in the world market.

Solid fuel units

In recent years, the Zhytomyr plant has mastered the production of boilers operating on solid fuel. There are 2 lines of heat generators available for the buyer to choose from:

1. Classic heaters of the AOTV and AKTV series, designed for burning coal, anthracite and firewood.
2. Pure wood-burning long-burning boilers “Zhitomir-D”.

The first line includes 18 models with a heat output of 12...25 kW with a steel fire-tube heat exchanger. The AKTV series is equipped with a cast iron hob, while the AOTV-V modifications are equipped with a copper coil that heats water for household needs.

Let us list the features and operating parameters of traditional coal boilers:

• combustion of fuel and emission of flue gases occurs due to natural draft in the outlet channel;
• the air supply and combustion intensity are adjusted manually with a special screw on the ash pan damper or with an automatic draft regulator on a chain (optional);
• the secondary copper DHW coil is located in the boiler tank;
• the manufacturer declares an absolutely real efficiency indicator - 78%;
• operating coolant pressure – 1.5 Bar, in versions with a round body – 1 Bar;
• the weight of the device is from 88 to 208 kg, the volume of the fuel chamber is 44–69 liters, depending on the power of the specific model;
• burning duration of 1 load of anthracite – 8 hours, firewood – 6 hours;
• The highest permissible supply coolant temperature is 90 °C.

Note. The heat generator comes with a poker and a scoop for scooping and cleaning the ash chamber.

In the operating instructions, the manufacturer directly states: solid fuel units are designed to operate in heating networks with natural circulation of water and an open expansion tank. In fact, adding a circulation pump is quite acceptable provided that the coolant pressure does not rise above 1.5 Bar.

The circulation pump in the gravity system is placed on the bypass

In closed heating systems, TT boilers must be used with a buffer tank (heat accumulator). Otherwise, in case of overheating, the pressure in the pipeline network will reach 3 bar, which is why the water jacket of the unit may swell and crack. The warning equally applies to long-cycle heat generators “Zhitomir-D”, whose characteristics are presented below:

• the line includes 3 thermal units with a capacity of 12, 16 and 20 kW, the main fuel is wood;
• the minimum duration of work from 1 full bookmark is 8 hours;
• the firebox volume is increased to 140, 195 and 250 liters, respectively;
• boiler tank capacity – 78 l;
• unit weight – 200, 250 and 290 kg;
• other parameters are identical to heaters of the AOTV series.

Important point. The manufacturer strongly recommends using long-burning boilers in conjunction with an accumulating buffer tank that can hold 0.35–1 m³ of coolant.

The long-burning boiler "Zhitomir-D" has an enlarged firebox, which makes it high

Positive and negative aspects of operation

In terms of ease of use and reliability, Atem TT boilers differ little from other heat generators in the budget segment:

• the heat source operates without electricity;
• combustion duration and efficiency strongly depend on the quality of the fuel (wood, coal) and operating mode;
• cleaning the firebox and ash pan is not difficult; access to the fire tubes is through the front door;
• If the operating rules are followed and there is no overheating, the device will last 10-15 years;
• you can cook food on AKTV series boilers;
• burning wood is a priori more economical than using other energy sources (excluding natural gas in the Russian Federation).

The most important advantage of Zhitomir-D heaters is the large volume of the fuel chamber, which determines the combustion duration. It is very difficult to find boilers of similar capacity among equipment from other brands. The real competitor is the Lithuanian Stropuva 20 kW with a firebox volume of 260 liters, which is significantly more expensive.

For piping a unit with a large firebox, the manufacturer recommends a classic scheme with a buffer tank (heat accumulator)

There is no point in listing the disadvantages inherent in all wood and coal boilers. Let us note the specific disadvantages of Zhytomyr devices:

1. The low threshold of the maximum coolant pressure does not allow the TT boiler to be safely operated as part of a closed heating system, where the water pressure can reach 3 Bar.
2. According to the manufacturer's recommendations, the temperature in the return pipeline should not fall below 45 degrees, otherwise condensation will form in the firebox. With natural circulation, it is unrealistic to use a classic piping scheme with a bypass and a three-way valve that protects against cold return.
3. Manual air supply control does not allow you to implement the optimal operating mode and maintain the desired temperature. The draft regulator only partially solves the problem. Request for the manufacturer: equip 2-3 models with an automation unit and turbocharging.

Organizing a home heating system without gas or electricity

To select alternative heating options for a non-gasified electrified home, with a low power consumption limit of up to 5 kW, several effective heating sources can be offered. To heat a house, you will need to choose one of the heat supply schemes using the following modern technologies:

1. Long-burning boiler, with two heating circuits for heating and domestic hot water and a tank for indirect heating of hot water. Available and cheap solid fuel can be used as fuel for such a design: firewood and its waste, coal or anthracite and any other fuel product in the form of briquettes/pellets.
2. The boiler is a double-circuit boiler, powered by liquefied gas obtained from a cylinder or gas holder installation.
3. Gas convectors running on liquefied gas.
4. Double-circuit liquid fuel boiler: heating oil, diesel fuel or oil processing.
5. Renewable natural sources: wind power plants, solar collectors and various heat pumps.

Once a heating source has been selected, the home owner will need to carry out organizational measures to ensure that the circuit becomes operational.

The stages of organizing a heating system in a simplified form can be represented as follows:

1. Before heating a house without gas, they carry out a heating project and develop diagrams of in-house heating systems.
2. Obtaining approval from regulatory authorities to begin operating boiler equipment. In this case, these are approvals from the gas service for connecting to a gas tank or installing liquefied gas cylinders, distribution systems and water utilities.
3. Invitation to a specialized organization for installation and commissioning of the boiler and other boiler equipment.
