Filling the heating system with water
Start the gas boiler begins with filling the heating system with water. Here everything is simple. modern two-circuit boilers do not require a special system make-up node. It is already built into the boiler and equipped with a special tap, which is usually located at the bottom of the boiler in the vicinity of the cold water connection. Open makeup tap and slowly fill the system with water.
Starting the boiler how to fill the system with water
A very important point in the operation of any boiler equipment is the pressure of the fluid. To control this parameter of the heating system almost all boilers are equipped with manometer. In the process of filling the system with water it is necessary to monitor the pressure and once it reaches 1.5-2atm, the filling of the system must be stopped. In principle, the boiler’s working pressure value can vary depending on the manufacturer and model, so consult the boiler manual for the exact working pressure figure.

How to pump the boiler expansion tank?
The expansion tank in the boiler performs an important function. it compensates for pressure spikes with temperature changes of the coolant, whether it is regular water or antifreeze. The tank itself consists of two parts, between which there is a membrane. In one part there is the coolant, in the other. air, by which the required pressure is created. And for normal operation it is necessary to periodically pump the tank. Below you will learn how to pump the boiler expansion tank and how to find out how to do it.
A common situation: you turn on the water and draw a bath. The boiler at this time switches from heating mode to hot water mode. While the water is drawn, the coolant is gradually cooled, and the expansion tank is not working at this time. And here when you already screw on the tap, the boiler should start working on heating again, but it does not happen. The reason is that the pressure has dropped drastically, so that the automatics simply block everything. This means that it is time to pump air and increase the pressure in the tank.
What can a clog in the circuit lead to?
The importance of air vents cannot be overestimated. Plugs in the circuit can lead to various processes:
Installing an air vent in the heating system prevents the formation of plugs and s. Running into them, the coolant stops. Sometimes the plugs cut off entire sections of the circuit with the radiators. When this happens, the pressure in the system increases. When it reaches a critical level there is an emergency release of coolant. This, in turn, leads to a drop in pressure. In this case there are many cases where the air has collected in the radiators, the circuit continues to work, only half of the radiator becomes cold. This significantly reduces the efficiency of heating and somewhat increases the cost of its operation.
For open systems one of the most serious threats is rust. The question of how to remove air from the heating system arises only at the design stage. Such circuits are assembled with a slope of pipes with a large diameter, respectively a lot of water in the system. Given the fact that the coolant is in contact with air and involves it in the circulation, the level of oxygen in the pipes is more than enough. Since it takes a long time to bleed air from the heating system, oxygen reacts intensively with metal. The result of the interaction is the formation of corrosion on the inner walls of the pipes. Rust sometimes eats away at the tank so much that you have to replace it.
The direct consequences of clogged circuits entail indirect consequences, which are no less dangerous:
Occurs if the valve to bleed air from the heating system and all sensors are good, and work properly. As a result of increasing pressure there is an emergency release of coolant, which leads to a decrease in its quantity in the circuit. After it cools down, the fluid in the system will be lacking, the pressure will drop drastically. If it does not meet the minimum required to turn on the boiler, respectively, the heater will not turn on. And from this point in the winter begins the countdown of time when the pipes will unfreeze. Depends on how insulated the house is. There are times when it happens in just three hours. In this case, unpleasant news awaits at home from work;
It happens if there is a failure of the valve to bleed air from the heating system or the temperature control equipment. Unlikely situation, but possible. The results of this are very bad. In the best case, the repair or replacement of the boiler, in the worst case. getting injured;
A very likely situation, the joints may not be tightened enough. When the pressure increases, they can’t stand it and they crack. In this case the hot coolant pours out of the pipe, in a fountain. Not only that the circuit must be repaired, but also the neighbors to do the ceiling, because you flooded it with the order of. This is the chain that a simple air leak in the system can cause.
A clog in the loop can lead to serious consequences, such as defrosting the system or causing an accident.
How to deflate a boiler
Operation of water heating systems can be accompanied by air in the inner cavity of pipes, radiators and heat source. If an air lock occurs, it leads to changes in the parameters of the heating medium in some areas or in the entire heating system. Boiler ballooning can lead to overheating of the heat exchanger and failure of heating equipment. Every user of autonomous heating system should know how to get rid of plugs inside the water system.
How to bleed air from the gas boiler? Forum Stroem House
Constantly displays an error E1, on the sensor pressure very often falls to 0, and the boiler shuts down, but usually the system water pressure is normal, but rare enough. I replaced the nipple but there was no change. Check the filters in the return flow, you have a clogged system.
After you flush it, the boiler starts making a noise, as if it was running water through the pipes with
The third is the control panel. DAEWOO boiler installed. The remote W21 hangs at eye level and some of the numbers can not understand what it says or the remote is faulty or can not somehow reduce the contrast on the remote. I did exactly that.
Boiler DAEWOO dgb msc in operation with remote control sensor. I do not understand the logic of operation, I think it is written everywhere that if you turn on the water temperature in the system, the boiler should run continuously pump. I had to pump a gram twice a week
I tried it myself and my acquaintance who has had the same DAEWOO for three years. At first, everything was fine, the boiler kept at a minimum g. Now it’s a little colder, I decided to add a temperature, set it to 55 grams.
When the coolant is heated in the region of gr. I took off the cover sound in the area of the heat exchanger, similar to the one that makes in my apartment with a gas water heater when the water is too hot unfortunately, there is no thermometer, but my hand is hot. Reduced the setting to around 50gr. That’s the thin copper on the heat exchanger? Pressure is in the 1,,3 bar range, I have refilled several times since September; extra.
DAEWOO Gasboiler boiler U0 not used since spring. Gas valve inlet valve open and valve above stays dormant. Tried to change the power supply all backwards, the upper one is open and the lower one is not.
Piezo gas valve at startup, no gas in the chamber. Pressure is fine, near the stove. When I installed it about 4 years ago, I didn’t care about the angle of the pipe, and when the rain or condensate gets in the unit, the heat exchanger is all oxidized.
Maybe the gas valve relay on the board is stuck. I do not understand the logic of operation, like everywhere write that if you turn on the work on the temperature of the water in the system, the boiler must run continuously pump. I have it somewhere doing 2 cycles of heating water to the set temperature the pump is running all the time. and then turn it off, wait for a while and then turn it on again and so on.
In room temperature mode it is almost the same, if it can not reach the set point on the remote control. Try pressing the lower left button once. In my opinion, it should be, in any case, my boiler works the same way. During the first cycles, it remembers the time for which the water cools to the desired temperature, and then shuts down the pump for this time. If you want the pump to work all the time, you need to turn it on through the service mode.
In my country house wall-hung gas boiler DAEWOO suddenly dripped heavily. Is it a serious problem, or is it a minor one, and I can keep using the boiler?? Leaks can be as simple as a worn gasket or a loose connection, as well as a dangerous malfunction. a leaky heat exchanger.
Perhaps it was triggered by the stall valve due to lack of pressure in the expansion tank. A small problem with the burning water. It is very hot, no matter how you adjust it. I don’t understand what the problem is. All according to the instructions were installed by experts. In addition, I changed the heat exchanger because of the scale, well, it is clear, the water is hard.
Information
And here’s what’s wrong with the DHW? You put it on minimum temperature, but it heats up to boiling water, and it triggers a forced shutdown of the boiler. This is no joke. I see a lot of questions about these problems, but as a result the manufacturer or service personnel are silent. So the unit isn’t very practical.
Open the front cover of the boiler. There is an electronic control box on the bottom right. It’s got a removable glass window on it. Take it off, there is a parameter control button and two resistors.
When you press the button, the LED lights up. There is a manual next to the window.
Try to control the low temperature resistance. The boiler DAEWOO has been working for 5 years no complaints. Before the heating season, turned on the heating system pressure began to drop, it cools down and does not turn on again until you add water to the system. I hired professionals to unscrew the drain on the water heater. The old extender left, cut into a new system extender for 18 liters cost 1 thousand.
The system began to work well, the pressure jumps to 0. Turn on the hot water a few times and the crackling stops. Which of the users of boilers DAEWOO faced with the problem of turning on the boiler by the temperature sensor does not turn on the first time but with a. They will burn, extinguish, respectively, and the pump so long they will not last. Try it yourself without interfering professionals. But in general, the work of the boiler does not complain, because it costs accordingly. You need to do the following: Three-way valve defective.
It does not switch the water flow from DHW to heating and the boiler goes into overheating. Boiler stands at 80 degrees Celsius, but it is too high, the boiler starts heating up quickly, and the water level rises above the ambient temperature. Clean or replace the heat exchanger to avoid popping out E3.
Can anyone specifically answer what in the boiler, does not work and gives an error E3? Error E3 poor circulation of the coolant: DAEWOO gasboiler dgbmsc boiler.
During heating mode periodically, mainly at night, the system pressure exceeds the limit and the dump valve is triggered. Afterwards it shuts down with a low pressure error the gauge hand drops to 0. Afterwards I add water and it works fine after turning it off. You have low air pressure in the expansion tank.
Close the heating valve in front of the boiler flow, return flow. Of course it needs to be disconnected from the power supply. Open the pressure relief valve, put a basin under it and drain all the water. Without closing the valve connect the machine pump with a manometer to the expansion tank, unscrewing the protective cap and start pumping air into the tank, while making sure that all the water escapes from it. Once all the water is out, close the dump valve and increase the value of the manometer by pumping air up to 1.
After that disconnect the pump, open the heating cocks. We add water using the make-up valve, checking the pressure gauge to 1. Let’s assume that the liquid, being heated in pipes. Expands and fills the regular expansion tank.
But the size of the tank is not enough to remove the excess of the heated water, the pressure increases and there is an emergency release through a safety valve. After the boiler shuts down, water from the tank goes back into the system, but since the boiler had an emergency release, the liquid in the system is not enough, the pressure drops below a critical mark. Everything, without replenishment of the system with water, that is, without human intervention, the boiler will not turn on.
If the air temperature outside is low. the defrosting of the system is ensured. And it can happen at the most inopportune moment. Now on sale are automatic water boosters which supply water to the system if the pressure drops below a certain level.
Homeowners, who leave their homes unattended for a long time, should pay attention to them. Typically, the installation of heating takes place during the warm season to have time to prepare for winter. During start-up, the boiler operates in medium mode, and the fall is still warm.
Therefore, when the heating is not so intense, the liquid expands insignificantly, the pressure in the system is within normal limits. But when the frosts come and the boiler will go to work at maximum load, the volume of heated fluid increases, and then it turns out that the regular expansion tank is not enough. To avoid such a scenario, you need to correctly calculate the heating system and install in time an additional membrane expansion tank, which is used in heating systems of the closed type, when the fluid flows under pressure, which creates a circulating pump.
It is difficult to determine the exact amount of water in the heating pipes, usually it is done by power: This is the factory setting, but if you want, you can select another mode of pump run out. The following parameters are available: P0.factory default setting; within the range set on the timer, when the burner shuts down, the pump also shuts down.
P5 mode of continuous operation of the pump, regardless of the operation of the burner. P9 within the range of the heater operating time set on the timer, the pump continues to run for the duration of this time.
The problem with the boiler DAEWOO OGB ICH in operation for half a year, at first everything was normal, now sometimes shuts down itself and there is no hot water or heating. After one hour it switches back on by itself and everything works again.
How to add water to the heating system with a two-circuit wall mounted boiler.
Need to check the pressure in the heating system: E8 Failure of the temperature sensor. Temperature sensor shorted or broken, circuit board. Intermittent fault can only be detected by putting an NTC sensor or card in for a while. It wants to work only with the lid open and it starts only once!
Trouble with gas-air mixture. In combustion cycle, if flame is yellow due to overpressurized exhaust closure. the ignition voltage becomes less than 0.3V Check E2.

The appliance is noisy when heating water
Modern boilers are quiet, so vibration, noise, extraneous sounds should alert you. Which can serve as an indirect cause:
There are also quite specific reasons why the boiler hums.
A lot of oxygen
Water in the pipes is oversaturated with oxygen, resulting in bubbles during heating. This effect leads to increased noise and vibration not only of the device, but also of the batteries.
trapped air in the system
If the boiler is knocking and puffing, it is necessary to bleed the pipes. On modern radiators there are taps. Loosen them and allow any trapped air to escape.
Large amounts of salts in the water cause them to deposit on the walls of the heat exchanger. Therefore the unit will hiss when heated. Heating rate and heat dissipation is also reduced. Once a year it is recommended to clean the radiator. A reagent pump is prepared and the cleaning fluid is pumped through the hoses.
How to remove the air from your boiler / heater
Trouble with fan operation
The fan runs on models with a closed chamber and forced combustion products venting. Why does it make strange noises when rotating, whistling:
- Grease in bearings has dried up due to placement over burner. The grease dries out quickly under the effect of high temperatures, causing the bearing to wear out. Part is being disassembled and lubricated.
Excessive pressure in the heating pump
Pump is pumping high pressure, need to adjust settings. Too much pressure in the system can cause an emergency situation. Adjust values by moving the white lever on the terminal box.
Lack of water in the system leads to serious overheating. First of all, check the thermostat values, set it to a lower value. Measure pressure, top up coolant if necessary.
- If the boiler howls, it is a matter of improper setting of the gas valve or bypass (jumper pipe).
- The gas meter may rattle when operating at high power.
- Worn valve makes rattling noises.
