Why the gas boiler does not gain temperature, what to do

Pressing and rinsing

Pressure testing is not always done, due to the lack of a special pump and reluctance to call a team, but if the heating fails in the midst of cold weather, the costs can be much higher!

It is especially important to check the new system and the one that, on the contrary, has been serving for several years. The cost of crimping in construction companies from 3000 rubles

Additionally, they can take a fee for leaving the facility (about 2 thousand rubles). By the way, a manual pressure test pump will cost 4.5-6 thousand rubles.

Specifications and device

Keber boilers are distinguished by reliable assembly and long service life. The manufacturer gives a 15-year warranty. Also, the units of this brand are characterized by high efficiency.

The complete set of the Keber gas boilers device includes, thanks to which it is provided:

• stable heating of the coolant;
• the most complete combustion of fuel.

In addition, these elements are distinguished by high anti-corrosion properties.

Due to the fact that Keber boilers have gas burners, the size of their fuel chambers is smaller than that of similar heating devices manufactured by other manufacturers. Thanks to the special design of the Danko automatic equipment, the fuel burns as efficiently as possible, even if the flame height reaches 7 cm.

Also included in the package is the Arbat automation, which is responsible for regulating the operation of heating equipment and its safety. There are five levels of protection. When the pressure in the water or gas supply system drops, the unit will turn off on its own. The design of the automation is simple, which has a positive effect on its reliability, and in the event of a malfunction, the repair will be simple.

It is worth saying that, if they wish, users can order a model from the Keber boiler manufacturer with a more expensive, but at the same time more reliable and high-quality Italian Eurosit automation. Such units can operate practically without third-party intervention.

The assortment of the company that produces Keber boilers includes a wide selection of models of different capacities: 10, 12.5, 16, 20 kW, etc.

Consider the technical characteristics of the device using the example of the Keber 12.5 floor model:

• type of execution - floor;
• combustion chamber - open;
• power - 12.5 kW;
• Efficiency - from 85%;
• mechanical control;
• - 1.62 m³;
• weight - 39 kg;
• heated area - 125²;
• the maximum water pressure in the heating system is 3 bar.

Incorrectly selected boiler in terms of power

The next reason for insufficient temperature rise is the opposite of the previous one. This is the case when the volume of water is calculated correctly, but the power of the boiler does not match.

The volume of water generally depends on the amount and volume of all heating devices and pipe circuits installed in the system, additional buffer tanks, separators, etc. If, based on the volume of the coolant, the boiler will have insufficient power, as in the previous described situation, the boiler will not have time to warm up this entire volume.

Features of the

The ATEM brand has invested all its efforts in the development and production of a high-quality device for autonomous heating. For more than 27 years the company has been giving heat to its consumers in the form of Zhitomir gas boilers.Since the appearance of the first boiler, a huge rebranding has been made, the device has received changes from an internal base of spare parts to an external design. Today the Zhytomyr boiler is a neat block of small dimensions with switching instructions that even a child can handle. The main quality inherent in boilers of this brand is the quality and reliability of the device. Product specifications have also changed with the advent of new technologies. Not only these components, but also many other facts allowed the ATEM brand to get the European Quality award.

About the manufacturer

Since 2006, Keber gas boilers have been produced domestically, which is part of the Tactical Missile Armament OJSC corporation. These heating devices are well adapted to the Russian operating conditions; they function smoothly even in places with very low temperatures.

If necessary, such heating devices can be used for space heating in the Far North.

The Keber assortment includes both household and industrial models.

Single-circuit and double-circuit units are distinguished. The former are used exclusively for heating, while the others provide the room not only with heat, but also with hot water.

Why are there problems with heating?

There can be several reasons for the problem. External signs will help to clarify them. First of all, the indicators on the thermostats are checked. Many users ask themselves: what temperature should be set on the boiler? The maximum and minimum values ​​are specified in the operating instructions. For models from different companies - such as Buderus, Bosch, Navien, Vailant - the indicators may differ.

Most often, the nominal heating temperature on the regulator is 80 degrees. However, experts recommend setting no more than 60 degrees. At higher rates, the water heats up more, and this contributes to the deposition of scale. When it covers the walls of the heat exchanger, the heat transfer is reduced. As a result, the unit overheats, and the system, on the contrary, does not warm up as a whole.

An outside temperature sensor measures the reading in the room. In accordance with them, it automatically regulates the heating.

If you have a similar sensor, then set the values ​​that are comfortable for you. Read more about setting up a gas boiler in one of the previous articles - on the page you will find a detailed description of heating control.

Technical parameters of gas boilers Atem

Atem produces:

• floor gas boilers Zhitomir;
• wall devices ().

Units with installation on the floor are further subdivided into single-circuit and double-circuit. Devices with two circuits can heat water for two or three consumers with low consumption. See the technical characteristics of all floor-standing gas boilers Zhytomyr in aggregate.

The capacity for the hot water supply of floor-standing installations with two lines is from 175 to 1400 l / h with a temperature difference of the heated liquid of 35 ° C. The device can be equipped with a circulation pump, which is installed as a function. Parameters of the model range of double-circuit gas boilers Zhitomir of the parapet type in the table.

Parapet 2-circuit units provide warm water flow from 160 to 345 l / h at a temperature difference of 35 ° C.

From the tables, we can conclude and make sure that the wall-mounted and floor-standing boilers of this manufacturer are adapted to the conditions of low gas pressure in the pipelines, and this is their huge plus. A weighty minus is the maximum pressure of the heat carrier in the heat exchanger, which is possibly quite low.For boilers mounted on the floor, this is up to 2 kgf / m², and for hinged boilers - up to 0.7 kgf / m². While imported counterparts can operate at a system pressure of up to 3 kgf / m². Therefore, you can make sure that the equipment from Atem gas is more adapted to gravity systems and small houses with one or two floors.

Experts do not recommend buying wall-mounted devices for 2-storey cottage buildings, since there will simply be little pressure for high-quality operation of the pressure system.

Why does the heating boiler constantly turn off

Similar malfunctions occur both in new, newly installed units, and those that have served for several years. External and internal factors become the reason. Users often complain that the boiler shuts down and does not turn on after a long period of inactivity. For example, at the dacha, you start the device only upon arrival, which may cause the system to freeze.

The main causes of the problem lie in:

• Incorrect power selection.
• Heating or hot water supply (DHW) system.
• Smoke extraction unit.
• Gas mains.
• Electrical part.
• Incorrect adjustment.

Both wall-mounted and floor-standing boilers are susceptible to malfunctions. What can be done to eliminate them? Find the cause and try to fix it.

Design features

The main elements of the Zhytomyr boiler are:

• the case in which the main components and equipment are installed;
• gas burner block located in the firebox. Here the combustion of gas and the release of heat flow occurs;
• recuperative heat exchanger, in which heat exchange takes place between the combustion products and the coolant;
• flue gas system, its duties include the removal of combustion products outside the boiler and discharge into the chimney.

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

1. Heat exchanger pipes made of heat-resistant steel have a rectangular cross-section, such a 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 exchanger up to 92%;
3. To increase the area of ​​interaction between the 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 underside of the turbolizers, keeping the pipe walls clean. To remove soot, periodically remove the turbolators and clean them of soot.
4. Gas double-circuit turbocharged boilers in Zhytomyr have a coil of copper pipelines around the heat exchange heating pipes.

The POLIDORO gas burner device is used to organize a stable gas combustion process. Its distinguishing feature is a single stage atmospheric burner. The edges of the burners themselves are made of heat-resistant steel, which allows maintaining the combustion mode with different gas supply to the furnace. Even at low gas flow rates, the heating of the edges is sufficient to maintain a 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. With a decrease in the ambient temperature, the temperature of the coolant increases.

Moving on to cleaning the column

We turn off the gas supply valve to the boiler. Using the key No. 10, unscrew the fastening screw under the boiler door and remove the door.

Disconnect the wire connecting the piezoelectric element and the ignition electrode.

Unscrew the thermocouple clamp with the key # 10. Unscrew the thermocouple from the valve with the key No. 9.

Note:

it is necessary to ensure that the thermocouple does not rotate during unscrewing.

We mark the depth of entry of the nozzle into the main burner so as not to disturb the boiler setting.

Using the No. 17 wrench, unscrew the nut securing the copper tube from the burner to the valve. Using a key # 10, unscrew the ignition electrode from the pilot burner and the copper tube from the pilot burner and valve. Using a flat-head screwdriver, unscrew the two screws securing the pilot burner.

The gasket installed under the pilot burner has deteriorated. It will need to be replaced.

We remove the nozzle from the pilot burner.

Tip: If the nozzle is stuck, you can lightly tap the burner with a wrench.

Unscrew the four screws securing the main burner to the boiler body and the screw that secures the body in order to be able to remove the main burner.

Lowering the main burner down, remove the copper tube from the valve.

We remove the main burner.

We take out the thermometer sleeve from the boiler body.

Using the key No. 10, unscrew the four screws securing the upper boiler cover and remove it and the insulation sheet under it.

We unscrew the two nuts securing the flue to the boiler body.

We remove the terminals from the draft sensor.

We remove the gas duct.

We remove the swirlers from the boiler heat exchanger. We clean them with a brush. If necessary, use a metal brush.

We clean the outside of the heat exchanger with a metal brush. We clean the channels of the heat exchanger with a brush to the full depth. We clean the bottom of the heat exchanger with a brush. We also clean the gap between the boiler body and the floor. We clean the exfoliated debris with a vacuum cleaner.

Using the No. 13 wrench, loosen the screw that fixes the depth of entry of the nozzle into the main burner and remove it.

We clean the burner with a brush and a brush, clean its holes with a vacuum cleaner. We clean the flue from dust outside and inside.

We clean the outer surface of the nozzle with a brush, then clean the nozzle holes with a needle or wire.

Note: the needle must be of a smaller diameter than the diameter of the nozzle orifice. Even a slight increase in the diameter of the nozzle orifice can affect the combustion mode.

We install the main burner in place.

We install the copper pipe with the nozzle and screw its nut onto the gas valve.

Only after that we fix the nozzle on the burner at the mark with the key No. 13.

Note:

this sequence is necessary in order not to strip the threads in the valve body.

Finally, we clamp the nut of the copper tube with a wrench No. 17.

We clean the pilot burner with a metal brush.

This is how the thermocouple must be installed in the pilot burner (tip of the thermocouple against the flame tongue).

Install the pilot burner on a new gasket.

Before installing the nozzle in the pilot burner, it must be rubbed a little against the tip of the copper tube for a better seal. The nozzle should also be cleaned or blown out.

Connect the copper tube to the pilot burner and to the valve with a # 10 wrench.

The rest of the boiler parts are assembled in the reverse order. When connecting, the ignition electrode should not be clamped with a key; it is enough to do it by hand, since it is made of ceramic and can easily crack.

We carry out control soaping of all compounds. It is possible to check the tightness of the connection of copper pipes to the main and pilot burners only when the boiler is turned on.

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

Before igniting the gas boiler and turning on the heating system, first it is filled with cold coolant, which, after heating, will circulate through pipes and radiators. During the first launch, everything is carefully checked so that the work in the future is uninterrupted, and the equipment does not require repair.

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

Why the boiler does not pick up temperature - reasons

We will look at the reasons for the malfunctioning of the main types of boilers: gas, electric and solid fuel.

Gas boilers

There are many factors why the boiler does not reach the set temperature:

1. Burner flame not adjusted.
   In this case, the maximum achievable temperature is only 60 degrees. And sometimes less. You can usually fix the problem yourself. It is enough to remove the screws holding the casing, turn the fuel supply regulator clockwise, thereby increasing the force of fire.
2. The system simply does not keep the water temperature.
   For example, at the outlet the temperature reaches 70 degrees, and at the inlet it is only 15. Most likely, the speed of the coolant is incorrectly set and you need to increase it. Additionally, it is worth adjusting the radiator system. If done correctly, the temperature in the remote radiators will rise. Sometimes a weak set of temperature is caused by incorrect installation of the circuit with natural circulation. Most often due to the wrong angle of inclination.
3. Automation malfunctions.
   Sometimes this provokes a constant shutdown of the nozzles when the temperature reaches 60 degrees. The problem is usually solved by adjusting the automation.
4. The system simply does not maintain the set temperature.
   If the power is set appropriately, the system may not work properly.
5. There is little pressure in the system.
   This is caused by too much lubricant inside the gas valve. Especially in older generation models. The problem is eliminated by removing excess grease.
6. The diameters of the pipe and hose that fit the boiler are different.
   The work is disturbed, the temperature rise is not correct.
7. The heat exchanger is clogged.
   It needs to be cleaned periodically, otherwise the system will not work correctly.

Other common reasons include: leaks in radiators and pipes, improper pump adjustment, incorrect installation, system connection, blockage of circulation by air plugs.

Solid fuel boilers

Among the reasons why the pellet boiler does not pick up temperature (or any other solid fuel), we can highlight the following:

1. Lack of capacity for a given area
   ... Power calculations may have been incorrect when purchasing the equipment. Or the house is very cold. When it has warmed up enough, the boiler will start heating normally.
2. Violation of tightness.
   It is necessary to carefully check all elements of the system for depressurization. If even small defects are found, they need to be repaired as soon as possible.
3. The chimney and chimney are different in diameter.
   The solution is to bring these elements in line with each other.
4. The chimney is blocked.
   Also, the damper may simply be closed or there is not enough oxygen for normal combustion.
5. Poor quality fuel.
   For example, firewood may be poorly dried, and coal may contain an increased amount of rock. As a result, the desired temperature is not reached.
6. Combustion chamber too small.
   If you put too much fuel in it, there will simply not be enough room for normal combustion. Quite a common reason why the boiler rises above the set temperature.
7. The selected fuel is not suitable.
   If you are using a pellet or pyrolysis boiler, it requires a special fuel. It is not recommended to use any alternatives.

Often, a rapid drop in temperature is caused by too long a circuit. In such a situation, we recommend that you do not use hot water supply during heating. It is wiser to install and use a boiler.

Electric boilers

Despite their manufacturability, such models may also work incorrectly. There are also many reasons why the boiler does not reach the desired temperature:

1. One of the heating elements does not work.
   It may simply be turned off, burn out, or bad contacts come to it. The first step is to double-check all the heating elements.
2. Inappropriate wiring in the house.
   In older houses, it may simply not match the boiler output. In addition, there may be just a weak voltage or constant surges. To solve the problem, you can use a voltage regulator.
3. An air lock has formed.
   It is not difficult to identify this defect. Usually, in this case, only one battery in the house does not heat up, and all the others are at normal temperature. It is enough to open Mayevsky's tap, pour water into the system until it is full and close it back. The airlock will go away.

A common root cause why the boiler does not keep the temperature is the clogging of the heating elements with scale. Some boiler models are especially sensitive to this phenomenon and poor water quality. Scale must be periodically removed from the heating elements so that the temperature is at the desired level.

Removing air pockets before igniting the gas boiler

Before igniting the gas boiler, you need to fill the heating structure with cold liquid heat carrier. But filling with water alone is not enough. It will either not work, or the degree of heating of the room will be insufficient. A full-fledged first start is impossible without bleeding the air accumulated in the system. Often, modern gas boilers have a special system that automatically releases air when filled. But often its effectiveness is insufficient: you will still need to manually reset air jams. Only then can the launch be carried out.

It is necessary to remove air plugs before turning on the gas boiler not only from the heating unit, circulation pump, but also from all heating radiators. The process should start with batteries - for this, as mentioned above, they are equipped with Mayevsky cranes. They are opened by substituting a container from below. There will be a slight whistle at first, indicating that air is gradually escaping from the system. After removing the plugs, water begins to flow. Then the taps are closed. A similar procedure should be done with each of the radiators. "How to choose a Danko boiler - types of heating gas boilers, features, advantages."

When the air from the batteries is removed, the gauge needle should settle at a certain value. Before igniting the gas boiler, the heating medium should be added to the system and thus fed. "How to turn on the Lemax boiler - operating rules."

The boiler does not heat water for heating

So, let's consider the main reasons why a gas boiler does not heat water for the heating system and what to do with this:

• airlock. It is necessary to inspect the heating system for the presence of air in the radiators. To eliminate this problem, you need to install an air vent. Its principle of operation is similar to that of an expansion tank, but it is able to maintain the pressure in the system. Using an air vent, you need to bleed air from the system. It is important to inspect the valve itself for the presence of mechanical blockage - the presence of scale is possible there;
• corrosion in radiators. It is possible to determine the blockage of heating devices by draining the water from the system. If the water flowed out dirty, then you need to flush the system until visually clear water appears;
• connection errors. Hot water may not flow if the diameter of the pipes is not the same as provided by the project or instructions. It is necessary to check the conformity of the pipeline, the correct connection and the quality of the installation of valves;
• insufficient network pressure. You should try to add water to the heating system, as there may not be enough pressure to trigger the automatic ignition of the burner;
• the presence of scale in the heat exchanger. The first sign is prolonged heating of the coolant and heating of the batteries. It is necessary to get rid of deposits and carry out boiler water treatment. To do this, you need to disassemble the boiler and dismantle the heat exchanger assembly.

Before that, you need to shut off the flow of gas and water to the device. Then, flexible connectors from the pump are connected to the heat exchanger and it is washed with a composition with a special cleaning agent, which can be purchased commercially. Then the parts are washed with water.

It is important to understand that the addition of chemicals to the coolant prevents and reduces the appearance of deposits on parts. But before using the reagents, you need to familiarize yourself with the boiler instructions, since some, "Electrolux", "Buderus", "Navien" or "Arderia", do not provide for the use of chemical additives in the coolant. In this case, you can use water purification filters or distilled water.

Some manufacturers allow the use of antifreeze instead of water in the heating system. This substance can be used in the following boilers: Baxi, Vaillant, Proterm, Beretta, Korea Star. However, it should be understood that each manufacturer recommends using its own antifreeze;

• clogged filter. If the filter screens are clogged with mechanical debris, the radiators may also not heat up well. Therefore, the filter should be regularly checked and cleaned by rinsing with water. If clogging occurs too often, then such a part must be replaced;
• incorrect setting. First of all, if there is little or no heating, it is necessary to check the settings of the control unit. An insufficient temperature can be set and the gas does not heat the water;
• malfunctions of pumping equipment. If the pump power is not sufficient to ensure good circulation, then it can shut down if it overheats. This can happen when the DHW circuit is turned on;
• incorrectly selected heating devices. If the system has radiators with inappropriate heat transfer and design parameters, this can also lead to poor heating;
• wrong slope of pipelines. This problem most often occurs in natural circulation systems. Normative documentation specifies that the slope of the pipes should be from 10 mm for each meter of the pipe. In case of non-compliance with these requirements, circulation may be disturbed and, as a result, there may be no heating due to the low flow of the coolant.

Varieties

To date, several types are involved in the production of Zhytomyr boilers - parapet (wall) and floor. In turn, floor products also have subdivisions for 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.

Equipping a single-circuit boiler "Zhitomir" primarily implies 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 two-circuit options.

In terms of their technical characteristics, floor standing boilers mostly have such similarities as:

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

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

Wall mounted

The same division as for floor-standing boilers is also present in wall-mounted boilers. They can also be single-circuit and double-circuit. The efficiency is the same for all devices. The same goes for gas pressure.

But still it is worth considering their characteristics p>

• the power of parapet boilers must be at least 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, the consumption of natural gas 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 still the model "Zhitomir-3 KS-G-020 SN" is in great demand. This device differs from its counterparts not only in terms of affordability in terms of the price factor, but also has clear technical data. The design of the device is designed in a minimalist style; 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 is a button for turning on and adjusting the settings of the device. In the same part there is a control window, with the help of which it is necessary to monitor the performance indicators of the boiler.

The basic configuration includes a housing, which also includes heat exchanger elements. Outside, it is covered with thermal insulation material and a casing made of steel. The burners are presented in the amount of 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.

Switching on the boiler

1. The gas boiler is plugged into an outlet.
2. The switch should be set to zero.
3. The gas supply turns on (the valve on the gas pipe opens).

Further steps may differ for different models of gas boilers.

For example, the switch for Aton or Danko boilers must be set to the "asterisk" icon, press the entire switch and hold it for 5-10 seconds.

Then, without releasing the switch, press the button located next to it.

The unit will respond with a characteristic click and hum. Then the regulator is released and the required power is set.

To turn on the Baksi boiler, you also need to turn on the gas, plug in the plug and press the "Start" button. Operation sound will appear. The device needs to be given a little time, and it will automatically ignite the flame. After that, you need to press the power button again and thus connect the heating circuit (the corresponding icon will appear on the display). In conclusion, using the buttons, the desired temperature is set.

We will consider the types of generators for gas boilers here.

To organize a full-fledged heating system in a private house, it is necessary to install a boiler. The article https://microklimat.pro/otopitelnoe-oborudovanie/kotly/kak-vybrat-dlya-chastnogo-doma.html discusses the main criteria for choosing heating equipment.

Reasons for frequent on-off gas boiler

It happens that an installed new device after setting, commissioning starts to turn on and off too often. Although such a device should automatically regulate its work, however, such a process clearly indicates system failures. This can have a detrimental effect on the life of the device, because the working elements begin to wear out quickly, and the device itself will fail.

There are reasons why a heated boiler is often triggered. In any case, it is better to contact a specialist if you lack professional experience, because you need to be careful when handling blue fuel. The main reasons for turning on / off heating equipment with frequent frequency:

• incorrect device selection. The power is provided for a large room, and the installation of the unit was carried out in a small room;
• incorrect installation of the circulation pump;
• the temperature range is incorrectly set;
• there is no thermostat in the room, for this reason, the operating state of the device is adjusted according to the temperature indicators of the coolant.

Important! This problem is quite simple, but there are times when you have to replace the device with another model.

Malfunctions of Keber gas boilers

Of course, any equipment can malfunction. Keber boilers are no exception. Let's consider the most common problems that the owners of such equipment have to face:

1. Unstable work . Usually this problem is solved by cleaning the jet. In some situations, it is necessary to check the meter, since it may not allow gas to enter the system in the required amount.
2. The gas burner goes out a few minutes after being turned on. There can be many reasons that lead to this, but most often this is due to the failure of the thrust sensor. The best thing is to contact a specialist.
3. There is no gas supply to the injectors. If you have purchased a boiler with Arbat automatic equipment, then, most likely, the stem is jammed in the middle of the structure. You can drip some machine oil yourself, then check the automatics for gas leaks. If the above steps are unsuccessful, then you should contact a specialist.

1. 2. 3. 4.

When arranging a heating structure, many homeowners prefer the installation of double-circuit gas boilers

When installing modern models, these heating units are reliable, they are economical and allow you to provide hot water supply in the house, but it is important to know how to start a gas boiler correctly for the first time.

Malfunctions of boiler units

The main malfunctions of gas boilers:

• the boiler does not start;
• damping of the burner;
• the gas boiler is not picking up temperature;
• the boiler does not turn off.

The boiler does not start

If the gas boiler does not start at all, the reasons may be as follows:

• the electronic or manual ignition system is out of order;
• there may be no voltage in the mains;
• gas supply interruption or closed valve on the supply pipe;
• insufficient or excessive gas pressure in the network;
• clogged burner nozzles.

Boiler automatic control unit

Since any gas units are complex technical equipment that is dangerous if misused, it is not recommended to repair gas boilers with your own hands, except for some simple cases. Repair or replacement of ignition systems, cleaning of burner nozzles in this case should be carried out by specialists with special approvals from supervisory authorities. Damage to the nozzle openings during cleaning can later cause such a phenomenon as the separation of the flames from the burner, which leads to an automatic shutdown.

The lack or excess of gas pressure in the network can be caused by a malfunction of the fittings, gas meter, etc., here the specialist of the gas company can also find out the exact cause.

Burner damping

Possible reasons for the burner to go out during operation or immediately after switching on, that is, when the gas boiler does not ignite, may be the following:

• insufficient, excessive or reverse thrust;
• the traction sensor is faulty;
• poor thermocouple contact;
• power outages or surges in the network to which the volatile boiler is connected;
• depressurization of the connections of the supply gas pipeline.

Draft reasons relate to boilers with an open combustion chamber and a natural exhaust system, although the effect of blowing out the burner flame with gusts of wind can also manifest itself in coaxial chimneys. All modern boilers are equipped with draft sensors that are triggered when there is insufficient draft and the automatics extinguish the burner. With excessive thrust, the rate of exhaust of combustion products increases, which causes the flame to burst from the burner, which is why the gas boiler goes out - in this case, the automation also blocks the flow of gas.Backdraft or air blowing through the chimney can occur with strong gusts of wind, while the flame in the burner goes out.

Specifications

Today, the products represented by Zhytomyr boilers are the most modern and in demand. To understand why this particular brand has received consumer recognition, it is necessary to consider the model range in more detail. Each individual equipment has a huge advantage over similar devices from other manufacturers. There are disadvantages in Zhytomyr boilers, as in any product, but the presence of advantages outweighs the importance, showing that the equipment has much more advantages.

Gas boilers "Zhitomir" have a number of advantages due to which they are in high demand in the market.

• The heat exchanger of the device is steel. Thanks to this, the water receives the maximum heat, which is formed during the combustion of the gas.
• The burner design is thought out to the smallest detail. It is this feature that contributes to an increase in the performance of the device, and the level of emission of harmful impurities is minimal.
• The imported automation of each boiler allows you to achieve the most suitable characteristics.

• Convenience of device management. No extra buttons and switches.
