Technical characteristics and design of gas boilers Zhitomir

General information about the manufacturer and products

The manufacturer of this heating equipment is. The brand has been known to consumers for over 27 years. Of course, the product has undergone many changes since its first release. The company is constantly refining and improving gas boilers Zhitomir in order to satisfy all the needs and preferences of customers. Thanks to all this, the company occupies a leading position in the market.

Excellent quality and reliability are the main characteristics that can be attributed to boilers of this brand. The products of this manufacturer have been repeatedly awarded with various awards. For example, “European quality”, “Golden Mark”. They have Zhytomyr gas boilers and the “Highest Standard” quality mark.

Gas boilers Zhitomir are designed for houses that are equipped with chimneys. The range is quite wide, which allows you to choose the most suitable model. Our article “Autonomous heating of a private house: choosing the optimal method” will help you on how to install autonomous heating in a private house.

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.

The gas supply mode is regulated by the EUROSIT gas valve. This device automatically switches the gas supply to the burners depending on the temperature of the coolant. The user independently sets the temperature of the coolant, focusing on the temperature in the open air. As the ambient temperature decreases, the temperature of the coolant increases.

Why Zhytomyr boilers?

Looking at reviews of gas boilers in Zhytomyr, it becomes clear why the products of this manufacturer are so relevant and in demand. The equipment has a number of undeniable advantages compared to similar devices from other companies. Of course, like any product, Zhytomyr boilers are not without their drawbacks. But compared to the mass of advantages, the disadvantages are insignificant.

The main advantages of the Zhytomyr gas boiler are given below:

1. The heat exchanger is made of steel. This allows the maximum amount of heat generated during gas combustion to be transferred to water.
2. Full compliance with all international standards.
3. Well-thought-out burner design. This makes it possible to obtain high productivity while releasing a minimum amount of harmful impurities during gas combustion.
4. Only high-quality imported automation is used. This makes it possible to achieve optimal performance.

6. Modern design.
7. The unit has compact dimensions.

The Atem Zhitomir gas boiler has many settings, thanks to which you can set the required temperature level. The device is equipped with special sensors that ensure that operation is uninterrupted.

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.

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).

Natural gas consumption, hot water output and the size of the chimney duct depend on the power of the heater. The specified characteristics are presented in the table, in more detail on the manufacturer’s website.

Advantages and disadvantages

The most important advantage of Zhytomyr parapet boilers is the price that is affordable for people with average and low incomes. Heating installations can be freely purchased in Ukraine and the CIS countries.

Let us list the other advantages of chimneyless heat generators:

1. Energy independence. The boiler does not require electricity, although it can work in conjunction with an external circulation pump.
2. Small size and simple design.
3. Reliability and safety provided by proven gas automatics from the EuroSIT brand.
4. A full-fledged smoke channel is not required.
5. The double-sided arrangement of the fittings expands the possibilities for connecting heating network pipes.

Important point. You should not perceive the listed nuances only in relation to Zhytomyr devices. The market is saturated with parapet clone boilers with similar pros/cons.

Design diagram of a double-circuit version of the heater
Despite the low threshold of permissible coolant pressure (2 Bar), wall-mounted boilers can operate as part of closed systems with a membrane expansion tank. The main thing is to maintain the specified threshold when filling with water and adjust the pressure inside the air chamber of the tank according to the instructions.

Since we profess the completeness and reliability of the published information, we will reveal the shortcomings of the Zhitomir-M heaters:

1. The degree of automation of the boiler is minimal and includes only a set of safety functions - protection against attenuation, overheating and a critical decrease in pressure in the gas pipe.
2. If the wall faces a windy passage, the burner may periodically go out. The problem is solved by installing an additional screen on the windward side of the chimney.
3. The performance of the hot water heat exchanger is enough to serve 2 consumers with low consumption. If you turn on the shower and the kitchen faucet at the same time, the water temperature will become uncomfortable for washing.
4. A constantly burning pilot light wastes fuel. This fact is critical for residents of Ukraine and other countries with high prices for main gas.
5. Manual ignition mechanism.

All safety, heating and gas control functions are concentrated in the 630 SIT valve

The disadvantages of heat generators are not critical and are a consequence of the maximum simplification of the design and reduction in cost. At the same time, the service life of inexpensive Zhytomyr boilers reaches 15 years, taking into account minimal maintenance.

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.

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.

This is most likely due to oxidation of the traction sensor, it does not see the contact and because of this it quickly goes out. It is necessary 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.

The lineup

At the moment, the company produces two types of boilers: parapet and floor-mounted. Floor products are divided into single-circuit and double-circuit. If it is necessary to equip only a heat supply system, then single-circuit options should be chosen. They are quite economical to operate. Due to the fact that the Zhytomyr single-circuit floor-standing gas boiler is equipped with high-quality imported components, it can be turned on and off repeatedly throughout the heating season. You can find out how to legally connect individual heating in an apartment here.

If, in addition to heating, the homeowner also wants to receive hot water, then it is better to give preference to dual-circuit models.

Such units are more expensive, but at the same time they are capable of performing both functions simultaneously. All floor products, regardless of model, have some similar parameters.

The technical specifications for the Zhytomyr gas boiler are given below:

• the maximum coolant temperature level is +90 degrees;
• Efficiency is 92%;
• The minimum operating gas pressure is 635 Pa.

At the same time, a single model has the following characteristics:

1. power ranges from 7 to 60 kW;
2. natural gas consumption ranges from 0.76 to 6.8 cubic meters/hour;
3. coolant volume in a gas boiler – from 14 to 70 liters;
4. For dual-circuit models, DHW capacity ranges from 175 to 1400 l/s.

Design features

The general structure of the Zhytomyr floor-mounted gas boiler is shown below:

The design of the water heating installation is simple and ensures energy independence for all models of the manufacturer. The gas burner is an atmospheric, single-stage type from the Italian brand POLIDORO, of simple design, whose reliability has been tested by time. The automation systems for gas boilers Zhitomir, made in Italy, are equally reliable in operation. The automatic non-volatile gas valve of the EURO SIT brand is the most popular among all manufacturers of boiler equipment; leading foreign and domestic brands install it in their products.

To transfer thermal energy to the heating system, the installation uses a fire-tube-type steel heat exchanger. This means that high-temperature flue gases pass through several pipes immersed in the water jacket of the boiler. They transfer their heat to the water and come out at a temperature of 110-150 ºС. The pipes have a rectangular cross-section, which increases the exchange surface area and makes the unit more efficient. In double-circuit versions of boilers, coils of a copper coil are located around the heat exchanger pipes to heat water for household needs.

To slow down the movement of gas combustion products in smoke pipes and make it multi-pass, turbulators are used in the heat exchangers of floor- and wall-mounted gas boilers. Their additional function is to absorb soot deposits. The latter settle on the planes of these parts located perpendicular to the gas flows, and soot practically does not linger on the walls of the pipes.

Subsequently, soot deposits can be easily removed from the turbulators, since when disassembling the unit they are removed from the smoke pipes. This technical solution allows the internal surfaces of smoke pipes to remain clean for a long time and effectively transfer heat to the water jacket. Otherwise, a layer of soot deposited on the walls can significantly impair their thermal conductivity, then the temperature of the gases at the outlet will increase and the heat will be released outside.

Household gas boilers Zhytomyr are adapted to chimneys with insufficient draft. For this purpose, the unit is equipped with a direct damper, which opens the way for flue gases to the outside, bypassing the heat exchanger. It works like this:

• The damper must be opened before ignition. By default, the chimney has insufficient draft force.
• The valve adjustment wheel and the piezo ignition button are pressed sequentially, and the igniter lights up.
• The wheel turns a couple of notches, gas is supplied to the burner and it ignites.
• High-temperature gases (up to 200 ºС) begin to flow directly into the chimney. Due to the temperature difference in the chimney pipe, the draft increases and the boiler enters operating mode.
• After 5-7 minutes, the damper closes and heating of the coolant begins, the improved traction force is maintained.

The Zhitomir parapet chimneyless boiler largely repeats the design of its floor-standing “brother”. The difference is in the design of the chimney pipe; in suspended models it is coaxial. This is a double-walled pipe, inside which combustion products move, and air from the street moves towards them between the walls of the outer and inner pipes. Accordingly, the gas burner device does not use air from the room for its operation, but takes it from outside, while the combustion chamber is closed. In foreign analogues, a fan is used to suck in air; in Zhytomyr units, the entire process is energy-independent and operates with natural draft.

Characteristics of gas boilers Zhytomyr 3

Of course, the manufacturer offers many different models. But the Zhitomir 3 gas boiler is especially popular, so it’s worth considering it in more detail.

The model impresses not only with its affordable price, but also with its excellent technical characteristics.

Many note its compactness, ease of use and attractive price.

Thus, Zhitomir boilers today occupy a leading position in terms of sales. High technical parameters, excellent quality and affordable prices make the products of this manufacturer very popular. Having decided to buy a gas boiler Zhytomyr, the user will never regret the purchase. After all, such equipment will allow you to organize reliable and uninterrupted heating of your home.

Heating boilers Zhytomyr

Heating boilers Zhytomyr When choosing heating equipment, it is important to take into account several indicative factors: reliability, company experience in the market, user reviews and the quality of the materials used. Each of the listed characteristics is important, therefore, the reliability of the proposed equipment is objectively assessed based on them. One of the options that meets expectations is Zhitomir heating boilers. After all, the manufacturing company has been working in this area for more than a quarter of a century, which has a positive effect on the level of manufactured goods. Why choose Zhytomyr The company that produces heating boilers Zhitomir is Ukrainian. It began its activities during the existence of the USSR, which explains the high quality standards and requirements that apply to each model. However, there are a number of other features that characterize the company’s products on the positive side: 1. Multi-level testing of each individual device. It is no secret that the basis of quality is constant control, monitoring of production status and collection of statistical data. For this reason, Zhytomyr heating boilers undergo seven-level inspections, which identify possible breakdowns during operation. This allows you to timely calculate the defect, while eliminating the entire batch. 2. High efficiency and energy saving capability. Purchasing new equipment, especially if its power is higher than the previous one, means increased maintenance costs. However, modern prices for utilities are not always affordable, so Zhitomir heating boilers offer different operating modes. Some of them provide very significant savings thanks to low-flame burners. This makes replacing equipment a profitable solution that pays for itself fairly quickly. 3. Cost of purchase and installation. Often, owners replace previous devices only after a significant breakdown that cannot be repaired. The worn-out condition is explained by the reluctance to spend a large sum on updating. Heating boilers in Zhitomir can be purchased at an attractive price, since all equipment is designed for the average Russian budget. An additional and very significant advantage for the manufacturer will be a wide range of models. It allows you to select a device according to individual parameters and requirements. This makes the purchase not only profitable, but also pleasant, because any useful and beautiful thing for the home can only please you.
