Bosch gas boiler
Please provide a list of minimum settings to reduce clocking. The room thermostat is not yet possible to use. And is it always necessary to adjust the gas valve during commissioning? Boiler Bosch Gaz 6000 W WBN 6000-24 C. Heated area 120 sq. m. Set the power to 50 percent. The coolant temperature is 70 degrees. It is heated so far only by radiators of the first floor in the amount of 5 pieces. The burner switches on and off every 5 minutes approximately.
Disadvantages of Bosch gas boilers
This high quality equipment includes a pressure vessel, burner, flue gas or condensing heat exchanger, as well as control and safety technology that comes ready to be connected to the built-in terminal box.
Associated Boiler Room Components
Various equipment options to meet customer requirements. The continuous flame tube ends in an internal flue gas recovery chamber with internal water, which leads to the first flue tube. Both the first and second smoke tubes are free of fittings. The highly functional round design ensures optimum pressure resistance. The oven, the volume of the water chamber and the radiant and convective heating surfaces are perfectly matched and coordinated with each other.
It is necessary to reduce to a minimum of 30%, you can increase the time between inclusions up to 10 minutes. And still it is possible to try temperature interval incl. / off change. Gas valve adjustment is a must.
Fault with EA error at the Bosch 6000 35 kW boiler. At first it was thrown off and it started. For the fifth time in a week and a half. Last night I checked it worked. Today at lunch I stopped by to check the EA error again. The error is reset, but this time the lighter clicks, but does not start. So five times before the error. I had to turn it off and unplug it. After that it started up. Whether it works or not, I don't know. I don't live in the house yet.
The front door of the boiler is fully articulated with hinges on the right or left. The entire cross section of the boiler is freely available. This facilitates maintenance, cleaning and inspection. High quality mineral wool insulation covering the entire boiler body and special thermal insulation materials on the front door keep radiant heat loss to a negligible level. If desired, the heat source can be supplied from operation with integrated flue gas or a condensing heat exchanger.
Bosch gas boiler
It is economical and heats up quickly. Heating on demand is great because you don't run out hot water. It instantly heats the water as it flows through it and so it doesn't need to be turned on sooner, this also saves electricity. Gas water heater constantly gives you the same constant temperature while they are running, and is supplied with gas rather than electric water heaters that slowly cool the water stream as the tank empties.
This error is only reset when the power is turned off, so there was no point in trying to reset it. Ground the unit if not grounded. Set the fan stage to a higher value (for example, I have 5 instead of the required 2 according to the instructions).
Double-circuit boiler 6000 chirps when starting and stopping, so it's scary. The device is new, the heat exchanger looked, washed, just in case. Did not help.
To run it, a regular internal gas cylinder and will give you about double the hot water for your dollar. The flow rate is 11 liters, 14 liters or 18 liters per minute. This is the amount of water it manages to heat up as it flows. Different capacities are important because 11 liters for example can supply a shower or sink, however if you have a water heater connected to more outlets that work at the same time, you may need a 14 or 18 liter flow.
Your choice will depend on how much you want to use at any one time. The main disadvantage is that of course you need to have a gas tank that is properly ventilated and positioned. Often this will be installed outdoors and run through no more than 6 meters of pipe length.
Do not torture the burner, the sound comes from the fan turbine when it is turned on / off. Remove the fan and adjust the balancing clips on the turbine so that they do not cling to the housing or tighten the nut on the turbine if it is loose.
Why is water about a glass by volume drained from the overflow pipe on the boiler 6000 at intervals of 20-30 minutes? The make-up tap is closed. Does everyone have this or is the unit faulty?
Gas water heaters generally use less energy and cost less to operate - you can expect savings of around 50% compared to an electric water heater, although you should consider that gas models are more expensive at the time of purchase. Around €250 for smaller models and up to €300 more for larger models.
Although this is the cheapest type of water heater and the most expensive, this type of water heater is usually the least durable. The electric display ensures that you are in complete control of the settings that allow you to use it in a way that saves on your daily consumption. Disadvantages have a submerged element of the water heater. Calcium develops rapidly on the element and this immediately reduces the heating efficiency of the water heater, so more energy is needed to reach the same water temperature.
As practice shows, in 9 out of 10 cases the boiler has nothing to do with it, it is just part of the system. It is necessary to call specialists and look at it comprehensively.
Tell me, if there is a thermostat in the boiler that opens and closes the contact, it cannot be connected to the Bosch 6000? Or should only the boiler temperature sensor be connected to the device?
This is just the sensor. I have an apartment of 32 meters with a gas boiler Bosch GAZ 6000 W. A couple of people in this apartment building there was a mistake on it. As a result, very dirty water was drained from the heating, because they filled it when there was still no water and the houses were completely new buildings, a new quarter. I want to bleed water from the heating and fill the circuit with a new one, but I can’t find in my passport how to do this, in what modes. The diagram shows the make-up tap and drain hose. How to properly drain the water from the heating and fill it?
Dry contact water heaters have a heating element that is inside a glass metal tube that permanently holds the filament. Non-absorbent element water heaters are more durable simply because the element is inside a metal dome so it does not come into contact with water and therefore does not corrode. Although they are between 60 and 100 euros more expensive depending on power, they also have a longer lifespan of 40% more durability.
Water tanks contain a special function to protect against overheating. The safety valve protects against emptying the tank in the event of a shutdown of the tap water supply and for the release of water in the event of an excessive increase in pressure. Magnesium anode protection also provides additional protection to the steel tank by focusing the harmful electrolytic process from the internal water tank to the anode. This is called a sacrificial anode, which protects the inner tank from corrosion and the heating element.
I understand that you have a two-circuit model. It is impossible to drain directly from the boiler. In the heating system, a drain cock must be provided for this purpose at the lowest point of the system. If there is such a faucet, then there are no problems - open it and Mayevsky's faucets on the radiators and drain. From the heat exchanger of the boiler, water will be pulled out by vacuum. If something remains there, then only in the expansion tank - it's okay: in the expansion tank, water does not participate in the circulation. The drain hose is the drain of the safety valve when the pressure in the system is exceeded.
The anode needs to be changed every 2 years as stated in the user manual. An internal glass lining is also added around to avoid corrosion of the steel. Because the water does not come into contact with the outer steel, it prolongs the life of the water heater.
The greenest of all available options, solar water heaters are a must in Malta if you can afford one or are eligible to apply for a government grant to help fund it. Solar heaters are filled with a liquid, commonly called glycol, which runs around the outside of the tank and heats the water. The water is heated by the so-called thermosiphon effect, which is a passive heat exchange method based on natural convection that circulates in the liquid without the need for a mechanical pump.
Bosch 6000, when you turn off and turn on the power supply, does it start by itself or do you have to manually start it up?
All boilers, including yours, start themselves when the electricity supply is restored.
Tell me about bosch bw 24c classic. It worked properly for 2.5 years, now when the hot water supply is turned on, the burner ignites and immediately goes out and so on several times in a row, then it lights up, but it does not work stably, that is, the water goes, then hot then cold. It's not comfortable to wash. Sometimes it goes out and does not light up at all. What could be, where to look, or immediately to the specialists?
Thermo-siphoning is used to circulate liquids and volatile gases in heating and cooling systems such as heat pumps, water heaters, boilers and furnaces. This means that over the years, solar water heaters tend to lose little or no efficiency.
Questions about malfunctions of Bosch boilers
Solar water heaters cost you nothing and you can use them in Malta all year round, unlike most other European countries, which are forced to pair it with a conventional water heater during the colder months. The system has a backup heating element when it is very cloudy or when the water has been used up.
Better service.
Boiler Bosch GAZ 6000 with coaxial. What to choose the fan speed at the first start, by default? The device is connected for heating and hot water. Email I didn’t connect the power supply, I didn’t purchase the stabilizer because there is an example of the operation of a Korean unit without a stabilizer for 8 years. And in general, any recommendations for the first launch are interesting.
A solar water heater can lower your electricity bill by as much as 50%. This is the greenest option as solar water heaters do not produce any emissions and are controlled by a limitless source of energy; sun. Modern technologies are very efficient at turning sunlight into heat, making even mild sunny days sufficient to run your system on solar power alone. Solar water heaters come in a variety of sizes and can be installed in a variety of spaces as long as they are mostly exposed to the sun.
Install a stabilizer.
Bosch 6000 24H does not heat the boiler. What's the question?
Change parameter 2.4E. Set to 0.
I bought a single-circuit Bosch 6000 and an ACV 130 boiler. How to combine them? The instructions only describe the dual-circuit. It’s clear on the water, but where to connect the temperature sensor, and which one is needed? Temperature sensor NTC art. Will 87004000140 work?
It's a thermistor! Naturally, there are no contacts there. A semiconductor that changes resistance with temperature. It works on the falling part of the current-voltage characteristic, which is why it is called the "Negative Temperature Coefficient". Which boiler, and the sensor and the boiler does not matter.
They can also work in partially shaded environments. The most common size constraint is roof space, so this may dictate which model you may choose. There are different types of mounts and we can tailor them to your specific situation.
Regular maintenance will increase its service life and ensure its efficient operation for a long time. 10 to 15 years is long enough that the water heater needs to be checked every 2 years. Normally a water heater simply requires a glycol top-up to keep it running efficiently, however a change to the assembly will extend the life of the internal tank.
Question about the room regulator, I do not know which one to choose. Bosch boiler 6000 24s, heating TP, supply temperature 45 degrees. Everything would be fine, the unit does not clock, warms up to 45 and works for hours at this temperature, as I understand it on modulation. Gas consumes little, the floor is pleasant. But it is not very cold outside now, and the temperature in the house in a few hours reaches 25-26, but the boiler continues to work. We have to transfer it back to summer mode, and so about 1-2 times a day. I need the house to have 23, and it turns off, but at the same time, so that the thermostat does not control the temperature of the flow line, and modulation too, the boiler copes with it so well. Which regulator is suitable, and are there any?
The cost of the service is about €. To find these suppliers, we suggest searching the Internet, advertising in newspapers, or consulting the Yellow Pages. Each product comes with a warranty that covers any manufacturing faults. Problems caused by improper plumbing or poor installation and commissioning are not covered by the manufacturer's warranty. A customer service representative will help you resolve the issue. Also, please be sure to keep a copy of your account number and model number when calling our customer service.
So you need a simple on/off thermostat. Better electronic with a small hysteresis. +-0.2 degrees. There's a normal output relay in the thermostat. When the relay is closed, an analogue of the jumper is obtained, which by default is in the unit at the terminals of the thermostat connector. Everything as you wanted. The temperature will be maintained, but there will be no power control, etc. On the boiler, this is a special input for the thermostat. He knows how to handle it.
The hot water heater should be installed as close as possible to the most frequently used hot water point. Other factors that may affect the position of the installation include the length and size of the gas supply pipe, the length of the hot water pipe, and the position of existing doors and windows on the home. The Australian Plumbing Standards include minimum distances and distances that installers must comply with.
The installer has the right to issue a certificate of conformity upon completion of the installation. In most cases a Certificate of Conformity is required. The installer will be aware of any additional government plumbing regulations that affect installation. Hydropower and pilot models are not suitable. All water heater installation and operating instructions now include an attached description of the water quality. You should still check regularly to make sure the valve changes automatically and arrange for an empty cylinder to be filled.
Last year, the AOGV-120 was accidentally replaced with a double-circuit Bosch 4000 with a closed chamber in a private house. They decided not to change the heating system (frosts were coming). Somehow they overwintered, although the system was old and very airy, they could not push it to the norm. in the spring, on your own replaced the system with polypropylene and aluminum radiators Royal termo 350. Techelman system. The system works with a room thermostat. There are doubts. At old system I did not notice gas savings compared to AOGV (worked without automation). It is almost clear that the system is not for a modern unit. Tell me, do I need to make adjustments to the boiler? The servicemen said that everything is set up and nothing needs to be touched. When working with a thermostat, what temperature should be set? I got used to the fact that AOGV burned in manual mode constantly, when it was necessary to add, subtract the flame. And now he is trying to put the regulator on 1-2. It seems to me that this is not correct, it heats the room longer, respectively, it burns more gas, and for the elderly, the main thing is saving. They really don’t like that all this winds up on the counter (the numbers on the stabilizer and the bulbs on the boiler). Do not retell how many shortcomings in this model. I beg you to tell me about the settings and temperature (to save gas). House 70 sq.m., radiators in a circle, heated evenly. Yes, still, what pressure to keep in the unit?
When there is an interruption in the gas supply or there is no gas in the cylinders, the water heater will attempt to light again. If the water heater does not light after a certain number of attempts, the water heater will shut down as a safety precaution and a reset will be required.
Your plumber will be able to measure the gas load of all household appliances and generate the required gas supply. The low temperature potential in your area will also be a factor the plumber will consider as the liquid in the bottle needs to evaporate and low temperatures reduce the ability of a liquid to turn into a gas.
At my w6000 model, at a set temperature for supply of 45 degrees, it switched to the mode of maintaining a small flame, but for quite a long time. Those. the boiler tries to work longer, but with low power than strongly raskochegarit and turn off. And I think the first option is more economical, because he knows better. A device correctly adjusted to gas pressure is 90% of its correct and stable and economical operation. It is impossible to tell by the gas settings, this should be done by competent commissioners with a pressure gauge. If you mean setting the boiler according to the parameters or adjustments available to the user, then this is all written in the instructions.
However, you should still check regularly to see if the valve has changed and lay down the filling of an empty bottle. Temperature and flow fluctuations can be caused by a number of factors: insufficient gas pressure, low or high pressure water, the difference between the pressure of cold and hot water.
There really isn't anything a consumer can test to see if there might be a smell of gas around the water heater. You should ask a plumber to check all gas lines and connections on the supply line. domestic gas to check for gas leaks and seal them if found. Purchase an appliance to ensure proper operation, which will ensure maximum energy efficiency.
Boiler 6000, new building, 80 square meters. The problem is the following: It does not keep the temperature. That is, with a small pressure, boiling water flows, with a large pressure, the temperature begins to float. Called the technicians several times. It all started with the fact that boiling water went into the heated towel rail, it was fiery. Then it gave an error E2, E9. On the unit, the temperature rose above 70 at the set 40 (I did not notice this before). The master came, dug around, removed the rubber gasket so that the pressure was greater, advised to reduce the power. At first it was normal, but the temperature swam hard, it was impossible to set a constant, it showed again 70 and above. Once again, he began to torment the masters. As a result, they said that it is better not to mix with the apparatus in the mixer, to regulate the pressure. Advised to increase the minimum pressure of hot water. As a result, I set the power to 40% (it had no effect on boiling water), the water pressure may somehow have affected. Need to re-try setting the minimum and maximum power?
There are only three reasons why your household water overheats.
1. With normal flow, too much gas enters the burner per unit time.
2. With a normal, correctly adjusted gas pressure (maximum pressure, since a wall-mounted gas double-circuit boiler always switches to maximum power in DHW mode), the DHW flow is too small. Household cold water passing through the secondary plate heat exchanger heats up and becomes hot, which is exactly what is called DHW for short.
3. 1+2. That is, the flow is small and the maximum gas pressure is too high.
There were problems with the boiler, the specialist checked the water filter again, said that the pump was working normally, that the heat exchanger should not heat up so quickly, and then drop the temperature just as quickly, looked at something, twisted it. Then he offered to reset the settings to factory settings. I tried, but it was of little use. It keeps 33 on heating, then the burner ignites, quickly heats up to 51 (45 is set for heating), then the gas is turned off, as I understand it - the pump turns on, the temperature quickly drops to 33 and lasts until the next start.
Turn the hot water on full, full power. Set the DHW temperature to 60 C (this is not for long) If the flow is about 10 l / min and higher, then with a properly configured burner, the temperature on the boiler should not float (but you should not see 60, in theory). In DHW mode, the unit displays the hot water temperature. Now close the water and activate the heating mode. If the temperature rises sharply and the burner turns off then:
1. heating circuit filter.
2. pump rotor and its speed should be 3.
3. Three-way valve - no voltage to the actuator.
3. Maximum power of the heating system.
How quickly does it raise the temperature in the heating circuit? In principle, it depends on the power consumption of the heating system, and its resistance, but given that it is not cold yet, it will rise quickly. Further, when the temperature is set, after reaching the set value, the burner does not turn off immediately, but works for some more time, in its own words, it creates an inertial heat reserve. Usually it is +5K to the set value and only then turns off. Plus casting at 1K is normal. Here you have 51 C. Further, after shutdown, the system activates a delay from frequent switching on - by default, 3 minutes and additionally introduces a temperature correction of -5K. Time delay is in any case a priority. i.e., if the temperature in the apparatus fell too quickly, for example, it changed by 15 K within 30 seconds, it will still stand for 3 minutes. A sharp drop indicates a large resistance of the heating system (and the boiler is part of it). At the same time, if after three minutes
heating circuit has not cooled down to the set value, the burner will not ignite. If you want to see on the display a constant maintenance of the set temperature, ask yourself the question - what is more important to you - 45 C in radiators, or + 22 C in the room. The latter is more important to me.
It is true that Bosch heat exchangers of all models are not covered with anti-corrosion aluminum paint. Other manufacturers Viessmann, Vaillant, Ariston, Baxi heat exchangers are covered with a special protective anti-corrosion layer. Bosch boilers have pure copper and this is presented as an advantage that other brands do not have. Is this really an advantage or are these heat exchangers just cheaper and they just save money?
Copper is used because it does not corrode. Well, by virtue of their physical properties. And this "anti-corrosion" coating quickly burns.
In which cases does the burner activate modulation - only when using a thermostat?
When the coolant temperature approaches the set one, the modulation is switched on even without a room temperature sensor, but this process may be too fleeting (before switching off) to be noticed. When using an OT thermostat, flame modulation will occur even when the room temperature approaches the set temperature. When using an On/Off thermostat, modulation and thermostat operation are not related in any way.
In operation, the bosch gaz wbn 6000W double-circuit boiler worked for two and a half years without any complaints. With the exception of clocking on hot water heating. recently done Maintenance, cleaned and adjusted. Stopped ticking. Then a couple of weeks later the sight glass in the combustion chamber flew out. Glued in place. In the summer, it occasionally began to turn off with errors 60 and 70. By the fall, malfunctions became more frequent. Now it happens, many times a day it turns off. Sometimes it works for two weeks. He opened, cleaned the fan, blew out the pipes from the difrele, disassembled, cleaned and reassembled the chimney, slightly straightening it along the way (there were slight bends in the knees). It seems that the fan began to blow weakly outward. Please help with good advice. And throw the idea of how to make an alarm for turning off the device.
If the fan is clean and the impeller is spinning quietly, then it is unlikely. Change the pressure switch.
Tell me how to make a sound alarm shutdown in case of a malfunction?
Simple methods - no way. Put a temperature sensor on the supply plus an electronic device, if the temperature is low, it beeps.
House 70m2 300mm foam block + 50mm mineral wool + ceramic brick cladding. In the future, I will add another 50-60 meters. On the ground floor there is a TP 33m2, radiators on the first and second floor. At this stage, the draw-off points are: a kitchen and a bathroom with a shower. Then I will make 1 more bathroom. I plan to install BKN Drazice 125. There is no riser, so the boiler will be wall-mounted with coaxial chimney. Considered various boilers. Bosch 6000 attracts for the price, and besides, it has an 18 kW model, and the bosch gaz 7000 has a minimum of 24 kW, I think it will often trip with my areas. For me, the main thing in functionality is that it can be used to set the temperature of the boiler water and for the future
connect some room thermostat or outdoor sensor (the last 2 conditions are not a fact). Is there a quality difference between the two models? Maybe the assembly location is different or something else?
Take the bosch gaz wbn 6000-18 and wstb 120 model.
As I understand it, the BKN can be connected to a double-circuit boiler in 2 ways: through a three-way valve and through a hydraulic separator. In both cases, as a consumer of the heating system (radiator), and it will warm up from the temperature of the heating system. This is understandable. And where to connect the DHW outlets of the boiler, or can it just be drowned out? I wanted to take a single-circuit Bosch 6000, but it is not available, and they offer a double-circuit one. If the outlets are muffled, nothing will happen to the heat exchanger, will it not burn out quickly without water? And you don’t want to keep the device always at the maximum, let it just warm the BKN longer. Moreover, I took the ACV Comfort 130, and it is a tank in the tank, I think, it will keep the temperature longer than with a coil. The disadvantage is that all boilers of this brand have a maximum pressure in the heating circuit of 3 bar, in the boiler safety valve also 3 bars. They say that if the valve gets stuck, then your BKN will explode. And I still think about a double-circuit boiler, so that in the event of a boiler failure, I won’t be left without hot water?
These conclusions can be left open, they are only for sanitary water. And it is possible to build a backup DHW heating line. But I don’t remember cases of failure of ACV boilers.
I ask for advice on two technical issues of organizing separate smoke exhaust gas boiler Bosch 6000:
1. Exhaust tract - does it make sense when switching from "pants" 80-80 through a tee with a condensate drain, to switch to a vertical chimney diameter of 100 mm? The cost of pipes 80 and 100 mm is close, on the whole pipe there will be a difference of 1200 - 1500 rubles, taking into account additional steps. The height of the chimney from the point of connection of the tee is 4500 mm, the outlet through the roof of the building is 5500 mm from the ridge, 10 degrees are taken into account.
2. Inlet tract. The air intake will come from a cold ventilated attic room. To the outer wall of the room more than 4 meters, not an option; Combustion air intake from the room is not an option. The distance from the intake point in the attic to the upper plane of the unit is about 1050 mm, including inside the boiler room - about 800 mm. AT winter period this air duct could serve as a source of several problems, the main one is the inflow of air with an almost outside temperature into the device (very bad), and abundant condensation on this very air duct, flowing onto its body. Condensation is cut off by insulating the pipe with various kinds of thermal insulation, but at the same time it remains and is aggravated
the main drawback of the scheme is the cooling of the apparatus with outboard temperature air. As a radical solution, I drew in my mind a diagram in which the role of the supply duct is played by chimney bath stove (diameter 100-110 mm) with a welded-on water register 300-500 mm long. Coolant circulation in the register - from CO, by a separate circuit. Difficult, but the result could be.
Tell me, please, which chimney kit to buy for bosch wbn 6000-24 c? It is necessary to go through a wall with a thickness of 375 mm, the outlet from the boiler is immediately behind the wall, there is no need to lead anywhere else. The prices for Bosch chimneys have risen, I would like to buy something cheaper, for example.
If you turn off the DHW flow sensor, then maybe it will be possible to reprogram it into a single-circuit device through the L3 menu?
No. Replacing the board from a single-circuit boiler. And the valve body from a single-circuit model, as well as install a three-way valve.
When operating from a regulator, can it be configured so that the pump does not turn off? It is due to the fact that both floors and batteries work in the house at the same time (we love warm floors). I installed the Bosch cr 12005 today, and now I'm sitting here thinking. The unit will bring the room temperature up to 25 degrees and turn off completely. The room will cool down, the floors will probably cool down too. In the future, when turned on, in order to heat up again to the set temperature, not much time will pass due to the high temperature in the batteries, and the floors will generally be slightly warm all the time. What is the best way to set it up here? And the second question, I press the middle button with the letter P, the hot water icon appears on the display, its temperature and time. What does it mean?
There is a problem with choosing a boiler between Bosch 4000 and 6000. I know about the difference in heat exchangers, preferably with an open chamber with an outlet to a vertical riser (130 mm diameter is available). What slows down the choice:
1. 6000 with a closed camera, which means you need an adapter with 60 mm plus aperture, the meaning of which is not yet clear, this is a minus
2. At 6000, a separate heat exchanger, this is kind of a plus
3. at 6000, at first glance, more complex settings, but there is no service in the district, this is a minus
4. Possibility of using with AURATON 1300 room regulator (installed and worked with an old ferroli boiler). And there are no spare parts for any boilers close.
Revealed the dependence of the operation of the ZWA24 boiler on the CO heating installation. If 3 and above, then it works like a clock. If 2.5 and below, then it is cut down on the first cycle or if hot water is turned on by mistake of the pressure switch (which I tried to deal with earlier). Maybe this is due to the gas supply settings (once, instead of resetting to the settings mode, the unit was accidentally transferred) or some other tricky process is going on there.
The apartment has a GAZ 6000 double-circuit boiler. I additionally bought an OpenTherm CR12005 room temperature controller, also known as TRZ200. Connected according to the instructions. It seems that the instructions for setting it up do not exist in nature, somehow figured it out. The device appears to be working. But I can’t understand: the device is already switching to summer mode and the temperature in the room has dropped by 2 degrees, and the sensor almost does not give a command to turn on, turn on for a few seconds and turn off. And without a sensor, the unit normally keeps the set temperatures.
Bosch 6000 single-circuit, gas outlet 3/4 inch, flexible piping, respectively 1/2. I bought the transition, actually two questions:
1 - Wind the fum on the boiler for the transition or through the gasket.
2 - Will there be any problems due to the transition, as I understand it, there will be a decrease in pressure.
They let me have a Bosch WBN 6000-24H single-circuit boiler, everything is working fine, but a question arose, his heating works together with the summer mode, the master said it should be so. But I don’t understand something, it’s clear for a double-circuit one, during the summer mode, the hot water supply works, and the heating is turned off. How about this? My heating and summer mode icons are on, and the heating is working. As I understand it, only one, or one or the other, should burn. And how the summer mode is implemented in a single-circuit unit.

We installed and connected the Buderus Logano G234-WS-44 kW boiler, Logomatic 4211 automation. Heating on cylinders without hot water supply, jets for reduced gas were also replaced. We survived the winter, the cylinders were replaced, all without problems. Then in the spring, when the temperature outside was +16+18, the boiler began to turn off for a long time and, when turned on, it began to give a burner error on the screen and a red button light on the front wall lit up. We pressed the button, turned on the power again and everything worked. It happened several times, then the boiler was completely turned off for the summer, what could be the problem?
In a single-circuit Buderus 072, is the BKN coil circuit heated by the same heat exchanger as for heating or the same as on a 2-circuit one that is used for hot water supply?
Tell me, for Vaillant wall-mounted gas boilers, are there any real / actual differences for the better in the new generation turboTEC plus VU / 5-5 compared to / 3-5?
Boiler malfunction, green LED flashes (power), the instructions say that the thermal protection has worked, the green indicator flashes, even if nothing is connected to the board. How to fix? I checked all SMD resistors and transistors, everything is in order.
In operation, a double-circuit gas boiler Daewoo Gasboiler with an electronic panel. When the hot water supply is turned on, the heating is heated, the operating mode is summer. Removed the three-way valve, there is no dirt and no production. It seems that the board does not control the three-way valve. How to check?
Installed and connected wall-mounted boiler Electrolux Basic Xi. A problem began that the boiler stopped seeing the flame and turned off the gas supply after 7-8 seconds. And after 3 attempts gave an error E1. How can I fix it?
Koreastar boiler malfunction. The heating works fine, hot water comes intermittently, when you turn on the hot water tap, cold water comes first, then boiling water. After a few seconds, cool, then again boiling water. What could be the problem?
Question: We installed and connected the Bosch 3000 gas wall-mounted boiler installed in 2013. I did the two-pipe system myself, one floor. The boiler is fed through a stabilizer. The house of the father-in-law who is absent for a long time in the winter. In the spring of this year, the boiler began to give an "AA" error and stopped heating in the heating circuit. Heat water is coming no problem.
In the instructions for the indicated error, it offers the following options: 1. Stop the pump. 2. Check the temperature sensor of the heating circuit. 3. Check for lime deposits on the radiator. Following these points, I checked the pump and heat exchanger, the pump shaft rotates, the heat exchanger is clean and there is no scale. Empirically established that when the boiler is turned on, it starts to heat the water supply circuit.
The three-way valve does not open the heating circuit and, as a result, the boiler displays the error "AA" overheating. Heating pipes are cold. After an unsuccessful attempt to start heating, he turned off the gas and simply restarted the boiler until the "EA r" error appeared, there was no ionization flow, and only after that the three-way valve opened the heating circuit and the batteries became warm.
Since the boiler is located in the area and far from the service, I decided to remove the electrical part of the three-way valve for the time being and open the heating circuit without hot water, in this state the boiler quickly warmed up all the batteries. I assume that some mode is enabled on the boiler that does not allow opening
heating circuit to the three-way valve. I did not have time to check the temperature sensor in the service mode. The solar panels mode is off for sure. How to reset the boiler settings to factory settings did not immediately find in the instructions?
Answer: There is no such mode for a 3-way valve. You may have a stuck water flow sensor. Disconnect the sensor and try to start heating.
Question: A Bosch WBN 6000 wall-mounted boiler is installed. When working on hot water, the burner ignites 8-10 seconds after the hot water tap is opened. Is that how it should be? (It's just embarrassing that other manufacturers do not have such a long delay) The ignition delay time is set to the minimum. (parameter 2.9E).
Answer: Look at the parameters: 1.6d - the current flow rate on the turbine - to understand the flow rate of water flowing through the boiler. 1.7s minimum hot water consumption - maybe something here. And most importantly, we look - 2.9E - the delay in the signal of the DHW turbine, the factory value is 2 - 0.5 seconds! put it down. How about water consumption in general? how many liters per minute look parameter - 1.6d. If everything is fine, take out the hot water turbine, clean it, blow it, it should rotate from the breath.
Question: I have a bosch wbn 6000-24c gas boiler in operation. Since last year. So far, I have not observed any special jambs for him. Yes, and there is no way to check the hot water supply in a normal way in the house, I still do not live, repair. So the question is: Can it be used for showering, will there be hot/cold water temperature drops? Or do you still need a boiler for it! I just noticed that already when washing dishes alone hot water after 3-4 minutes the temperature of the water drops.
Answer: The Bosch wbn 6000-24c boiler is a traditional wall-mounted double-circuit boiler, hot water circuit works in a flowing way, like a gas water heater, while the heating is turned off. it is convenient to use such a boiler when hot water points are located nearby and turn on separately, first one then the other, otherwise the temperature will jump, if it is far away, you will have to shed a lot of water before the temperature goes constant.
Question: I have a double-circuit boiler. There is also a basic understanding. It was decided to make make-up from the water supply collector to the return pipe. Single pipe system. This is right? Is it better to make a drain valve from the return line too? I just watched how people had heating done and there they made water into the heating pipe.
Answer: Make-up separately in the supply in order not to touch the boiler make-up. Boiler feed is harder to change. I bought a valve of 2 pieces and rejoice. If it doesn’t hold, I changed the axle box crane and that’s it. In general, this is a make-up tap, the system is filled from an external tap in the absence of a boiler on the wall! So it seems to be necessary to put an external tap.
Question: The Bosch gas 6000 24 kW wall-mounted boiler is connected and connected, there is no external temperature sensor. Yesterday I installed the trz 200 thermostat. The instruction was only in Turkish with it, so I figured it out almost at random. I read the instructions, it became a little clearer what is written there, but unfortunately not much, maybe someone has it in Russian? In principle, I figured out how to program it, but the question arose - it works very strangely. In room 22, I set the manual mode and set it to 25.
The boiler starts up, the burner turns on, it works for 30 seconds, it cuts out, the purge is in progress, at this time the boiler panel displays that the summer mode is on. another 20-30 seconds pass, the burner starts up again and everything repeats, again for 30 seconds and falls into summer mode.
At the same time, the coolant temperature does not rise above 35 degrees (but is set on the boiler 45), so several iterations occur and as a result the boiler is cut down, hanging in summer mode. in the room as it was 22 and left. coolant in the region of 25. In automatic mode, everything is the same. It seems that the thermostat does not care about the temperature in the room, although it shows it correctly (there is another independent sensor to check). Maybe I'm doing something wrong?
Answer: When my boiler was launched by Bosch, and specifically Bosch 6000, it also did not run the system. The symptoms were such that it warms at the outlet, the temperature rises wildly, and the water entering the boiler is cold. The boiler is connected to single pipe system f-100 mm, (then I’ll change it to batteries), So the masters were tormented and airy, then I have everything that is possible, etc., etc., because they are too lazy to mess around.
Everything was solved by lowering the pressure in the system, dropping it to 1 and then adding a bit through the additional valve (I don’t know what it’s called from the bottom of the boiler, it stands between the first and second pipes. It all worked. But there is one thing, the burner turns on periodically, the noise rises. When it turns off it doesn't matter whether it's a noise or a fan or a pump or something else.How it should work in general.There is no room temperature sensor, the boiler is constantly set to one temperature.
Question: We launched the Bosch 6000 double-circuit gas boiler with the programmer CR12005, the coolant temperature is set and here and there 75 C, the temperature in the room is 21 C correctly, and the coolant temperature walks (the lower the outboard, the higher in the system).
Answer: She should walk - automation saves you gas.
Question: the heating of water for an indirect heating boiler in a single-circuit boiler occurs only when the umbrella turns on the boiler for heating, or can the boiler turn on by itself to prepare hot water, regardless of whether the thermostat closes the corresponding contacts? I now have the DHW temperature set in the boiler menu, and the boiler temperature sensor is connected to the corresponding connectors in the boiler. For heating, the boiler is not working now, because the temperature in the house is higher than that specified in the umbrella settings. Can the boiler itself turn on to heat water in the boiler?
Answer: if you do not have OT, then the umbrella for the boiler is an ordinary room thermostat. Therefore, the boiler will heat up according to the readings of the boiler temperature sensor and the boiler settings.
Question: A Bosch 6000 gas boiler is installed. When a certain temperature is reached, should it turn off or maintain this temperature by modularly regulating the gas supply? my burner does not turn off, but the temperature stays plus or minus degrees, is it supposed to be like that? And is there any gas overspending in this mode?
Answer: If the minimum power level of the burner corresponds to the heat loss, then the boiler will continue to work. No, there will be no excess gas consumption compared to the "on / off" mode. To optimize flow and increase comfort, it is recommended to install a room temperature sensor.
Question: I plan to install a Bosch boiler with an on / off type regulator. Here's what I don't understand: circulation pump always working or not? When the burner is not working, does the pump drive the coolant? Or is everything turned off? The problem is that my heating pipe passes through a cold vestibule. And in severe frosts there is a negative temperature. I’m thinking, if the pump is turned off and there is no circulation of the coolant (ordinary water), will the pipe in this cold room not be defrosted at a time when it will be warm in the house itself?
Answer: It is configured through the menu from 1 to 10 minutes. ( factory setting- 3 minutes after the burner is switched off).
Question: Boiler BOSCH GAS3000 24kW (closed combustion chamber) in operation for 1 year, the problem started from the first day when the hot water tap was opened, the water temperature fluctuates between hot and cold. I contacted service center who serviced this product, they came five times, twisted something, changed the valve, then something else, in the end they changed the brains of this boiler (they said that this is an original from Germany).
At first everything seemed to be fine, but then everything started all over again. I noticed that when the heating is off from the mountains. there are no problems with water, the temperature does not walk, and when the house began to heat, everything started all over again. I don’t know who to contact and is it possible to solve this, maybe this is a normal phenomenon for these boilers and in order to comfortably use the shower, you need to install a boiler?
Answer: Options:
1. Flush both heat exchangers.
2.Set the minimum and maximum pressure on the gas valve.
3. Replace the DHW temperature sensor. Option #1 is the most likely.
Question: Tell me: the Bosch wall-mounted boiler stopped, the pressure rose to 3 bar, it gave an E9r error. I tried to restart - earned, after 10 seconds. the pressure jumped to the maximum, I stopped everything, turned it off, released the pressure. I checked the gas pressure - normal, as it was. What could it be?
Answer: If the system is new, then the expansion tank is small, if the old one, then the expansion tank is faulty, or maybe the make-up is poisoning. In your case, the error expansion tank the most probable. If so, then option 2: pump up pressure, replace the tank.
Question: After opening the hot water tap and igniting the burner, the Bosch boiler gives an E2 error (the flow temperature sensor is faulty). This happens in 10-15 seconds. After closing the tap, the error is removed by itself, and the boiler continues to work in heating mode. If the faucet is opened
again, the situation repeats itself.
To complete the picture: An additional circulation pump was installed in the heating circuit, before its installation, the boiler and in heating mode showed an E2 error for a couple of seconds, and then changed to E9 (the heat exchanger temperature limiter worked). Water source - borehole pump(water supply pressure from 2x to 3x without sudden jumps).
Answer: Possible reasons such:
Faulty own circus. pump (if it is only activated with DHW mode?).
- strainer clogged.
- Well, the sensor, probably, should not be ruled out.
Question: There was a choice of buying a boiler. I was specifically interested in the Bosch BW Exclusive ZWC 24–3MFA model. 2 contour turbo. I did not find information on this manufacturer. Anyone with info please share. Interested in quality, reliability, weaknesses, where they are assembled.
Answer: I operate Bosch BW Exclusive ZWC 24-3MFK single-circuit + boiler. The country of manufacture is on all boxes of Wernau, Germany, in fact Turkey has the most modern plant for the production of heating equipment there (a friend worked in Bosch and the issue was studied thoroughly). In terms of reliability: the line is new and there are no special statistics, but the previous lines were very reliable (according to a large number of reviews).
The quality of workmanship is quite high, everything is included in the kit, including the connecting panel on the wall (but still Ball Valves I recommend replacing it). Weaknesses are a plate heat exchanger for preparing hot water and a three-way valve, but with regular maintenance everything will work without failures. The choice is good, but it’s better to take a single-circuit + boiler and don’t save on the controller (I have the FW200).
