Main technical characteristics

The assembly of Keber boilers is quite reliable. They can serve for a long time. Among other things, the manufacturer gives a guarantee for their operation for as long as 15 years. Thanks to high-quality components, Keber gas boilers are also considered very economical. If necessary, this equipment may also be used for heating premises in the Far North.

Gas-burners

Efficiency and excellent operational characteristics of boilers of this brand are ensured primarily by the fact that the manufacturer has provided for very high-quality Danko burners in their design.

These elements are:

• provide stable fuel combustion;
• are distinguished by high anti-corrosion properties;
• provide the most complete combustion of fuel.

The use of high-quality gas burners allowed the manufacturer, among other things, to reduce the size of the fuel chambers in Keber boilers. The efficient work of Danko in terms of fuel combustion, in fact, made this equipment so economical.

Long burning boiler design

First, you should study the device of a long-burning boiler and its principle of operation, which differs from conventional units. The body of the apparatus has a round shape and is arranged according to the principle of "pipe in pipe", in the interval between which water is enclosed. This shape allows the most efficient transfer of heat from the walls of the furnace to the water jacket. The flue gas connection is located in the upper part of the housing. To supply hot water to the house, there are double-circuit boilers, in the water jacket of which a heat exchanger for heating water is built.

Homemade solid fuel boilers for long burning

At the front, the unit is equipped with a door for loading firewood, and at the very bottom - an ash pan. The latter is separated from the combustion chamber by a grate. A vertical pipe passes through the lid, at its end inside the firebox a load is fixed, to which arcuate air swirlers are welded from below. The chamber is filled with fuel, it is ignited from above and pressed down by a load with a pipe, therefore the principle of operation of a solid fuel boiler is to burn fuel from top to bottom. Air enters the working area through a vertical pipe, which descends with the load as the fuel burns.

Boiler automation

Of course, modern heating equipment should be not only economical and easy to use, but also safe. Natural gas is an explosive fuel, unfortunately. In this regard, Keber boilers have also earned relatively good reviews from consumers.

OOO Trading House Zvezda-Strela equips the boilers supplied to the market with the time-tested Arbat automation. In total, the units of this brand provide five levels of protection. So, for example, in the event of a pressure drop in the gas pipeline, the Keber boilers are automatically turned off.

If desired, consumers can also order from the manufacturer of this equipment and its complete set with even more reliable expensive Italian EUROSIT automation. Units of this type can be operated practically without any intervention of the owners of the house or personnel in the production.

Technical characteristics on the example of model 12.5

Thus, using Keber boilers is quite safe and convenient. Excellent performance of this equipment is ensured, of course, first of all, by its well-thought-out design. The gas boiler "Keber 12.5", for example, has the following technical characteristics:

• power - 12.5 kW;
• Efficiency - at least 85%;
• control - mechanical;
• gas consumption - 1.62 m3 / h;
• total heating area - approximately 125 m2;
• maximum water pressure in the heating system - 3 bar;
• weight - 39 kg;
• guaranteed uptime - 22,000 hours

This floor-standing single-circuit boiler has an open combustion chamber. This modern model belongs to the group of non-volatile equipment.

Types of boilers Don

Gas boiler Don-20

The production uses machine tools from the well-known concerns TRU M PF and Amada. Boiler parts are characterized by high dimensional accuracy and quality. Don units operate reliably in different operating conditions and function from 15 to 18 years.

Types of boilers are produced:

• gas;
• solid fuel.

The heat exchanger has an original design and provides for the repair or replacement of the heating element.

Gas

The boiler models are equipped with a gas burner. The unit is used in closed and open heating systems. The Don 16 gas boiler does not require regular tossing of wood or pellets. There is no problem of storing fuel stocks and cleaning combustion waste.

The unit works effectively if the main gas is supplied to the house, connecting cylinders is not recommended if there is no gas holder. The gas does not give off soot when burning, and does not clog the chimney and heat exchanger. The discharged products have a temperature lower than the discharge from solid fuels, therefore, condensation does not form on the walls of the structural elements.

Solid fuel

Solid fuel model

The heating unit is made of steel, cast iron, and the heating element is made of copper. Provides manual or automatic fuel supply, as well as the extraction of combustion products (ash). Coal, peat, firewood, coke or fuel particles - pellets are used. Electronic coordination systems make the equipment reliable and volatile, the device can work in a single-circuit and double-circuit heating system.

Floor-standing solid fuel boilers Don require regular cleaning from scale and soot deposits. Scale will overheat the metal and cause damage. Soot reduces heat exchange between pipes and combustion products, from which the energy carrier does not heat up to the required temperature indicators.

Consumer opinion

Despite the fact that Keber boilers are one of the cheapest brands of heating equipment in Russia today, they have earned quite good reviews from consumers. To the poles of these units, the owners of houses and apartments primarily refer to their impeccable work. For the first few years, boilers of this brand usually do not require any special maintenance at all. Some problems with their operation for the owners of country houses may begin to arise, judging by the reviews, only about 5-7 years after installation. At this time, it is recommended to clean the Keber boiler once purchased from limescale. This is primarily due to the fact that the water on the territory of Russia in most regions, unfortunately, is quite hard.

Thus, reviews of Keber gas boilers on the Web are mostly positive. The only thing is that sometimes the owners of country houses still criticize the work of the domestic automation of these models. It happens that after several years of operation, for example, the operation of the switch-on function deteriorates in Keber boilers. Burners are ignited in them only some time after pressing the "Start" button.

Gas boilers "Keber": instruction

Heating equipment of this brand, like any other similar one, can only be installed by licensed specialists. Before starting up in the boiler, all connections must be checked for tightness.

Instructions for turning on the Keber ignition head are as follows:

• turn the control handle counterclockwise to the ignition icon;
• without releasing the handle, press the piezo ignition button (a torch should appear);
• release the handle 20-30 seconds after pressing the button;
• check for the presence of a flame on the ignition head.

As you can see, the operating instructions for Keber gas boilers are quite simple. If there is no flame after performing the above steps, all four operations simply need to be repeated. In this case, it is necessary to increase the holding time of the handle.

Operation and repair of the Keber boiler

The gas boiler Keber KS-G-10 of 2010 is in operation, the temperature shows 50, but it stands at 2 and does not turn off. Is this normal or fraught with consequences, or is there something wrong? There are such cases that he himself completely extinguishes, you have to re-ignite the wick. But if he switched to a low flame, then the temperature on the sensor would, I think, drop, but it does not drop, so it does not go or what? You probably meant on the thermometer, and when the temperature is reached, the sensor switches to a low flame, and if it is exceeded, it turns off the main burner. If everything is in order for you, then the temperature is not reached. This happens when there is a circulation pump, or large heat losses. Move the knob towards the unit, if the burner goes out, then everything is fine in this part. A floor-standing Keber 12.5 boiler with Arbat automatic equipment was installed, until now everything was flawless and now there were malfunctions. To my remarks that after reaching the desired temperature, the main burner should completely go out and re-ignite when a certain temperature is reached during cooling, the master does not agree. He states that there should be a low flame on the main burner. As a result, I have a high gas consumption. And yet, where is this thermal valve? Didn't you find anything else in the instructions, except for the thermocylinder and the thermocouple? Yes, the boiler must rise to temperature, switch to low flame and when the set temperature is reached, turn off the main burner. You need to check the thermal valve, judging by the time and symptoms, it is time to change it. But here is the problem - the Russians can no longer be found, and the Chinese work as they want, plus they also need a master to be able to tune him. If the nozzles on the manifold light up when switching to low flame, then the problem will have to be solved. The thermal valve is located under the cover between the white button and the numbered knob. The gas boiler KS-G-25-06 with Eurosit 630 automatic equipment, produced in 2011-2012, is in operation. The door with the factory sticker is lost. Is there any other way to identify its number or at least the year of issue? The number and year of issue is in the passport, and the year of issue can also be viewed on the burner. The boiler has a power of 10 kW, and the burner is 24 kW, do they not fit together? Yes. Your boiler needs a 12 kW burner. I decided to change the entire automatic burner. Since there is no other way to solve the problem with the device. I am advised to burner Gobert 24. Will it fit my Keber boiler and will it solve my problem with the main burners not extinguished? Gubert is not very familiar with the burner, but he looked at it, it looks the same as everything that is sold with us. The only thing that caught my eye was that it was not equipped with a gas sieve valve, but a Chinese one, which was cheaper. The burner is selected according to the power of the boiler, see what you have, and set this power. And there may still be a problem with the installation of the thermal sensor. The Keber floor-standing boiler is in operation, a flame is burning from the nozzles, tell me what is the problem? The bypass valve needs to be changed. Tell me, the Keber 12.5 boiler with Arbat automatic equipment is constantly going out. What is the reason? The wires go up from the thermocouple and where the contacts are fixed at the top, move them, they tend to oxidize on the contacts. Malfunction of the KS-G boiler. I put on "6", the temperature rises to 60 degrees and turns off. It cools down to 40-50 degrees and turns on again. What is the reason or is it supposed to be? Most likely, there is a traffic jam in the system. It is also possible that the thermostat is not configured. Malfunction of the Keber KS-G boiler 12.5. Some puffing was noticed in the pilot window during operation.This phenomenon is alarming, there is also a problem, it is as follows, in the position of the regulator for 3 or more, the main burner stops turning off, the device works without stopping. When I return the regulator to 2, the boiler starts to work as expected, it worked - it turned off, according to the prescribed cycle. Tell me, what could be the problem? If the temperature corresponds to the figure, then most likely the gas pressure is low. The thermocouple on the Keber 12.5 floor boiler (Arbat automatics) broke down, I went to the store, there is a thermocouple without a union nut, and on the device it is a union one, I did not unscrew it, but it seems to be a union one. Ordinary thermocouple, unscrew and replace with a new one. The gas boiler Keber KS-G-10 with Eurosit 630 automatic equipment is in operation, up to position 3 it works normally, i.e. reaches a certain temperature and goes to the wick, keeps the temperature, from position 4 it starts to raise the temperature, i.e. burners burn constantly, does not go over to the wick. On 3 it picks up to 60 and goes to the igniter, on 4 the burners burn constantly and the temperature rises to 100, after which the burners go out a little. Two days ago, it worked fine, at 6 it kept 80-90 degrees, i.e. gained 90 degrees passed to the igniter until the temperature dropped. If by 3 it reaches 60 degrees and goes to the igniter, and at 4 it does not gain temperature, then either a weak gas pressure, or a low boiler power or large heat loss. The temperature sensor is responsible for the temperature, if it is not working, then it will boil at any number, perhaps not all of the kerosene has leaked out and it still covers the gas passage, check for another 3+, if it does not go out, change the temperature sensor. In operation, the Keber gas boiler does not raise the temperature above 50 degrees, what could be the reason? The reason may be low gas pressure. Malfunction of the Keber boiler. Small, with hot water, installed in December 2012. Worked well. Two days ago, it seemed as if the gas pressure in the network was reduced (the gas stove is working), and the boiler went out, since all winter it was at a minimum with the knobs with numbers, even the gas tap to the unit had to be reduced (in frosts, the pressure was increased, and mine even before that was at a minimum). I solved it like this: I opened the gas tap, the wick was lit with the 5th click of the piezo, after a minute of holding the igniter button, the burners lit, burned out for 2 hours, went out. Time is night. 2nd attempt: the wick came on with the 12th click of the piezo, the burners lit up after 5 minutes of holding the ignition button, burned out for 2 hours, went out. Time is midnight. 4 more attempts to ignite it to no avail. Second night without heat. The wick lights up quickly, 1-3 clicks of the piezo, it burns while I hold the button (I was tormented for about half an hour last night), release the button - the wick goes out, the burners do not ignite. Tried in the morning, afternoon, at night, again in the morning. Tell me, is there a problem in the boiler, or wait for an increase in gas pressure in the network? It was a thermocouple that burned out. Now replaced, it works properly. With a new thermocouple, the device turned on immediately, worked, warmed up, reduced it to 80 ° C, (it worked flawlessly, the flame was strong, it could only be reduced with a tap). Now it has gone out, and now the burners also do not light up. The wick lights up, the thermocouple is in its place, it is installed with a screw, it will not move somewhere to the side, it is in a flame. I release the igniter button after 5 minutes of holding, the wick dies out, the fire remains very small (maybe the remaining gas in the tube burns out), does not reach the thermocouple, the burners do not light up. Orion automation, boiler KS-G-10-04. What can be wrong? We checked the thermocouple, it works, it is heated, it gives a current. What else could be the cause of the problem? Maybe in the traction sensor, or what is the name of the hollow tube (on the wire in the winding), which is inserted into the hole in the upper part of the tank of the apparatus, on our left? And on the right, a wire from the thermometer is inserted into the hole. The wound tube is a thermal sensor. The traction sensor is higher, either wires or a tube go to it.Take out the thermometer. You do not have a draft sensor, since there is not a native thermocouple. Now what needs to be done - where the thermocouple is screwed in, there is a square nut of the thermocouple, tighten the nut a little, and then tighten the thermocouple only with a little effort so as not to crush it. If you need the thrust sensor to work, then a gap is placed between the thermocouple, the nut and the wires with connectors, we connect the sensor and the gap. Now about the temperature sensor, if it is damaged, the unit will not respond to temperature. We replaced the thermocouple and the igniter tube with new ones, the boiler lights up, runs smoothly, does not puff, but another problem arose. There is a small flame between the white button and the temperature control knob from the fuse. You can detect it with a lighter when checking for gas poisoning, when you light the device, there is no flame on the fuse on the igniter. Only when you turn on the burners. Tell me, what could it be? This is not a fuse, but a burner low flame adjustment screw. There is a rubber ring on it, and it is poisoning through it. Ideally, replace the ring, otherwise, if the bypass valve is configured and there is no overshoot, put out the boiler and drip thick paint into the hole where the screw is. Wait until dry and turn on the device. A gas boiler KS-G was installed and connected, for 250 sq. m. When firing up, it does not turn off, the temperature rises, if I am not mistaken, the automatic Arbat 1. The flame is not regulated - too large. What to do? Adjust or replace the thermal sensor. In operation, the floor-standing boiler Keber KS-G-16 K has been working properly for almost 6 years. Recently, it began to click when heating and cooling. System without pump (metal pipes). Tell me what you can do yourself? Will he hold out in the winter? Does not affect the speed. It is in the boiler that some kind of metal heats up and cools down. It will last more than one winter. The back, where the hot water comes out of the boiler, should be slightly higher for the air to escape. Gas installed. boiler KS-G-10, Eurosit 630 automatic equipment. Installed, started. A minor malfunction has emerged; during ignition, only the left side of the pilot burner lights up. I let go of the control handle - it goes out, I turn on the ignition again and then I ignite the right side, and then everything goes according to plan. The unit works perfectly in all modes. Problem with ignition of the pilot burner. What do you recommend to do? Remove the igniter and slightly bend the center and right sides with a thin screwdriver. Malfunction of the Keber-12.5 boiler, Arbat automatic equipment, 2005. At the point of contact between the thermocouple and the automatics, gas is poisoned, ignited when the flame from the burners goes to the wick. Yesterday I started up the boiler, and this morning I found a light, the automatics from it warmed up. I looked due to the fact that the batteries did not become hot, that is, after they ignited there, the burners did not light up anymore. How to neutralize the leak and shouldn't the automation shut off the gas supply completely in this case? If there was a fire, then the magnetic plug could melt and the rubber ring could become coarse. Eliminated by replacing the plug and ring. What happens if the pump does not work. There is no electricity and the boiler is on fire. Nothing will burn, for example, a fuse or something else? If the automation is working, then everything will be fine. The boiler will heat up and turn off, there will be one igniter, which will turn on again when it cools down. Malfunction of the Keber boiler 12.5. The click is audible, the regulator goes like clockwork, the bellows at the end warped, or rather the metal sheathing, like a sleeve, where it fits with the spring, I don't know how dangerous it is and how to explain it more correctly. The flame increases and decreases on its own as needed. I didn’t see if it was switching to the wick, I watched for half an hour, there was no more time to look. The only thing that is not for me, that is, as before, the flame is stronger. Therefore, I suspect that the bypass screw was still turned.I put the draft sensor in place, the hole for it was simply screwed on with a screw, I eliminated all leaks, installed a gas filter in front of the apparatus. What should I do to still turn off at the wick? The bypass screw is responsible for a low flame, and it is not worth turning it back and forth. The fact that the flame is regulated is good, but if the thermal valve was turned on, it is very bad. You will not be able to configure it yourself, and, as I understand it, you do not have masters. And yet - the flame is stronger when turned on. The thermal valve is responsible for the transition to the igniter, if everything else is normal. Keber 10 is installed for a couple of months, I put it on 3, gains 50 degrees and turns off, but the radiators are not hot. He let the air out of the radiators, but there was no point. I called a specialist, he said that the pump is heating up, replace the pump. I put a new one more powerful, but it also heats up and nothing has changed. What could be the reason? If the gas boiler reaches the set temperature and turns off, then the problem is not in the unit. Check if the system is full. Malfunction of the Keber 12.5 boiler, Arbat automatic equipment. They installed new automation, domestic, not Chinese. When turned on for 1, 2, 3, 4, 5, it burns for a minute, one and a half, and then only the wick and the burner does not light up again, the fire jumps out onto the nozzles. On the 6-ke, it does not burn for long at first, then the flame is low and the fire jumps out onto the nozzles, when you extinguish it, then after 15-20 minutes the burner lights up again and burns the same, constantly, does not decrease. How to adjust? Mounting screws for an asterisk or a conventional screwdriver. Bypass valve and temperature setting required. We connected the gas and installed the KS-G 10 boiler, the temperature does not rise above 60 degrees, what is the reason? There are many reasons - from gas pressure to heat loss at home. The Keber boiler with Orion-21 automation is in operation. It happens like this - I press the ignition valve, the gas goes to the igniter, it lights up. The valve was held even for 3 minutes, I release the valve, and the burner does not light up (gas does not flow). The igniter goes out (in normal operation the main burners should light up). I checked the draft sensor, it is closed (normal), 18mV comes out from the thermocouple during normal ignition of the igniter (like the same as the norm?), The thermocouple is washed by the flame well, the "Stop" button is closed (normal), maybe an electromagnetic valve (I call it, it shows shortly). Should there be a resistance of 18mV? No characteristics are written on the valve. Wherever the thermocouple goes, it branches to the thrust sensor, right? Then check the contacts, better solder. Tighten connections well. Possible problem with oxidation of contacts. If this fails, connect the thermocouple directly to the gas valve. Check what exactly does not work for you. You cannot leave without a draft sensor.

Possible equipment malfunctions

Like any other equipment, floor-standing gas boilers "Keber", of course, can sometimes break down. Most often, owners of country houses with this equipment have the following problems:

• unstable operation of the igniter;
• shutdown of the burner some time after the start of work;
• lack of fuel supply to the injectors.

In the first case, the cause of a malfunction in the Keber gas boiler may be a clogged nozzle. Also, sometimes the igniter is unstable simply due to the fact that the meter does not allow a sufficient amount of gas into the system. To remedy the situation, the owner of a country house, respectively, needs to either clean the jet, or properly adjust the operation of the monitoring equipment.

There can be many reasons for the shutdown of the burner after starting work. But most often this happens due to the failure of the thrust sensor. It is unlikely that you will be able to eliminate such a malfunction yourself. Only a specialist called to the house can cope with it.

If the gas supply to the injectors in the model equipped with the Arbat security system has stopped, then, most likely, the stem is jammed in the middle part of its structure. In order to eliminate this malfunction in the Keber gas boiler, in this case, you should drip a little machine oil into the device. After that, be sure to check the unit for gas leaks.

Heating boiler jacket

The utility model relates to power engineering and can be used in the production of heating boilers for heating individual and industrial premises and other technological needs.

Heating boiler jacket consists of a chamber of a liquid coolant placed between the walls of the body and the combustion chamber, on the side left and right, top and rear surfaces. The chamber is equipped with an inlet for the cold heat carrier, the hole is located at the bottom of the rear side of the boiler. The chamber is also equipped with a hole for the heated coolant to exit it on the upper surface of the boiler. The main difference from existing analogues is the location of the liquid coolant chamber directly over the boiler surface on the left and right side, top and rear surfaces, and the same difference is that the chamber inside does not have a single space, but is divided into horizontally directed sections with connecting channels in in the next order, on odd ones, the connecting channels are located on the side surfaces of the shirt, and on the even ones on the back surface. The declared utility model in the effective heating of the coolant due to the advancement of the coolant through the system of channels inside the chamber and due to the location of the coolant chamber, reduces fuel consumption, respectively, reduces fuel costs, as well as simplifying the design without losing the efficiency of heating the coolant
