Baksi does not heat hot water in the boiler. The boiler does not heat water. The boiler does not heat hot water. Baksi double-circuit gas boiler does not heat water

One of the problems that can happen when using a double-circuit boiler. The boiler does not heat hot water. The main and most common reason why the boiler does not heat water well is the heat exchanger is clogged.

In this article I will describe how I treat this problem. Thus, you can also get out of the situation if you have a double-circuit boiler with a plate heat exchanger.

I have a well at home and the water is very hard, so I constantly have problems with hot water To remedy the situation, I use citric acid.

The task is this. How to deliver this acid to the inside of the heat exchanger with the least effort. I found such a way. I have a magnetic converter at the entrance to the boiler, which should remove the hardness of the water, but it does not remove it, in my opinion this is a fiction. But for me it is good that it is installed directly at the entrance to the boiler. You can see it in the photo below.

It has an American nut on it, unscrewing which you can easily pour citric acid into the inside of the pipe.

But for this you need to turn off the water. Next to the boiler I have a collector. He is in the photo below.

Now all the ducts on it are open and with one easy movement I shut off the water supply to the boiler.

All water is blocked, now you can unscrew the American on the magnetic filter. And do not forget to come up with something, from the flowing water from the boiler, there is not much of it, but it is there. I wound up the rag.

Then I pour citric acid into the inside of the pipe.

I spin the American back and open the supply tap tap water into the boiler.

Now it is important to understand when the acid enters the heat exchanger. Since my water tap is located a meter from the boiler, I determine whether the acid has reached the heat exchanger to taste. I just open the faucet in short jerks and taste it, how “sour” went, which means the entire system from the magnetic filter to the faucet is filled with citric acid.

Next, you need to turn off the tap so that your family does not drain all the acid ahead of time.

I refuel the system at night and until the morning I have it acidified. In the morning I open the water supply valve to the boiler and drain all the acid. The water will sizzle, don't be alarmed.

A question may arise, but will the acid heat exchanger not eat through? I poked around on the forum of chemists and came to the conclusion that organic acid (citric refers to it) is harmless to copper.

I use this method as needed. If you don’t like how the boiler heats water or the pressure of hot water has become weak, I take and process the heat exchanger with citric acid.

If you have polypropylene connections to the boiler, and there is no place to fill the acid, then think of something similar, it will not take much time.

This video is the solution to your problem!

Watch until the end and you do not need to call a specialist.

Without boilers in climatic zones Russia will not survive. And this also applies to the warmest areas, Sochi, Anapa and Rostov-on-Don. Winters are still harsh and people cannot survive without heating. Therefore, it will definitely not work without heating systems and hot water. And only boiler houses can provide the city with all this. Today, let's take a look at the reasons why. boiler does not heat water- how to solve this problem and what to do for this......

They are very different. It all depends on the heat source. They can be either steam or water. They may vary in location. If the house itself decided to build its own boiler room, then a specially separate room in the house can be allocated for it. Or they make extensions to the house for these purposes. One of the main requirements for the construction of boiler rooms is good ventilation.

If the boiler works with steam, then very high demands are made on the quality of water purification, and then on steam. Therefore, it will definitely not work out at such boiler houses without a whole complex of purification plants. This includes the AquaShield electromagnetic softeners, which are highly valued by boiler house employees today.

If a gas boiler suddenly stops heating water, the reasons may be different, but most often when using water from central water supply without water softeners, lime deposits may be the cause. And hard and poorly eliminated. The table shows possible signs of the cause of the boiler shutdown due to scale.

Other reasons for stopping the boiler are simpler. Maybe a piece of scale can get stuck in the pipe and block normal operation, and a crack in the gas boiler can also contribute to a shutdown. But in these cases, there will definitely not be scale residues on the walls of the equipment. If the boiler room is not installed or treatment facilities, then the root cause of course is the hardness of the water. If the treatment facilities are standing, and the equipment was checked recently, then most likely this is not the problem.

In any case, if there is no cleaning in the system, then you will have to urgently deal with this cause and solve it. For boiler rooms, there are a number of water softening devices that are suitable:

AquaShield;
Ultrafiltration and conditioning for steam boilers;
Ion exchange for economical consumers of gas boilers

The most wasteful process of purification and softening will be in steam boilers. There will have to remove not just all organic and inorganic impurities. Even dissolved gases will have to be removed. Degassing is quite troublesome and costly. But the operation of the boiler depends on the quality of the steam. This is where membrane softeners work to make the water completely isolated.

AquaShield is chosen by many consumers of gas boilers for the simple reason that it does not need to be looked after and it does not need to be spent on it. But its biggest advantage for boiler equipment was and remains the ability to eliminate even the most difficult places old lime deposits. Usually, to eliminate such residues, the equipment needs to be untwisted, the spare parts are soaked in aggressive acidic environments and kept there for up to two hours. But even after that, you have to clean the surfaces with metal brushes or cleaners. If your gas boiler does not heat water to the desired temperature, then the reason is scale deposits. The electromagnet does all this work without damaging surfaces, at the molecular level.

AquaShield is an electromagnetic water softener (converter) that protects your boilers from scale, lime and rust.

Baksi or Ariston boilers are particularly reliable and safe. Breakdowns of Baksi double-circuit gas boilers should be repaired only by a specialist. But major faults can be removed on your own if you have a basic level of knowledge about the design of Baksi or Ariston double-circuit gas boilers. So, the boiler does not heat water, hot or cold, what to do, what is the reason? Most of the faults are indicated on the display of the gas boiler. Having a decoding of errors, you can figure out what is the reason for the boiler not heating hot water. Where to start the search if the water heating in the Baksi or Ariston boiler does not work, and the indicator does not show an error, or it can be determined in different ways. The Baxi boiler (baxi) has been operating for 5 years. For the last 7 months, such a problem has appeared: the gas boiler does not heat the water, although I set the temperature, for example, to 79 degrees, turn on the hot water, and the water runs at least 43 degrees. The house is large brick, double-circuit gas boiler Baxi, Ariston and Navien. At the same time, the Baksi boiler does not heat water, what is the reason? House in the village this moment no one lives due to the fact that the double-circuit boiler does not heat the water. Well, it’s not that it doesn’t heat hot water at all, but instead of the established 33 degrees, the water is only 17-19 degrees. Double-circuit gas boiler Ariston and Navien with a boiler. On the display of the control unit lights up that everything is working properly. Then what is the reason? This, as I understand it, why the boiler does not heat water? It spins in any direction. It does not give any effect. On the remaining pumps of the Navien and Baksi gas boiler, when recirculation is in progress, it is felt when you touch it. Because, as 78 degrees on a double-circuit boiler and 53 hot water, which is very strange. If the boiler does not heat water, the reason is unknown to you, then call a specialized company. if the gas boiler does not heat the water to the required temperature, then this is a boiler breakdown and it needs to be urgently repaired. For example, repairing a Baksi and Ariston boiler will cost 30 euros. And if the boiler does not heat hot water and refuses to work, it means that it is scale and it is necessary to clean the boiler heating element from scale and rust. Often the Baksi boiler does not heat water due to scale deposits or hardness salts on its heating element and heating elements. We offer to buy and install AquaShield from scale in the boiler. There is a Vaillant boiler, which also does not heat hot water, although the boiler is double-circuit and should work perfectly well. Maybe the water pressure sensor at the Ariston gas boiler failed? Where is he located? What does it look like? I do not know what to do! What is the reason? Why the boiler does not heat water, I do not understand.

Individual heating and hot water supply have long ceased to be something unusual. It is convenient and practical, besides, it allows you not to depend on the whims of utilities. Well, if some kind of trouble suddenly happens, for example, it turns out that the boiler does not heat water, then you will have to fix the breakdown on your own.

No, this does not mean that you have to arm yourself with a tool and start repairs yourself - for this there are specialized companies that provide such services. If the heating boiler works properly, but does not heat the water, then the specialists will repair it, adjust the boiler in accordance with your wishes, and, if necessary, do it. All work will be done to a high standard and guaranteed.

Modern gas boilers- reliable and powerful heating devices that also perform the function of heating water. They successfully combine seemingly incompatible things - unsurpassed efficiency and compact size. But their uninterrupted operation is possible only under the condition of regular Maintenance, detection and elimination of the slightest faults.

Malfunctions of heating boilers

Basically, major malfunctions begin to appear during the heating season, when two boiler circuits are operating - heating and water heating. It may happen that it does not start at all, or it does not heat well enough. With the launch, the issue will have to be resolved separately, but if it does not heat the water enough, then the reason may be the clogging of the heat exchanger. As you know, the quality of water in our systems is far from ideal, and besides, few users install it in front of the boiler. So the heat exchanger becomes clogged, resulting in poor boiler operation.

Here are the most common malfunctions of gas boilers in the event of which it weakly heats water:

randomly shuts off periodically
smokes heavily,
does not develop enough power,
making noise
clogged
the pump is broken.

If it so happened that the gas boiler does not heat the water, then often the reason is the formation of limescale on the walls of the heat exchanger, which, as it accumulates, becomes very durable and not only reduces the temperature of the water, but also reduces throughput boiler. The thermal conductivity of scale is ten times less than metal, so it is not surprising that the boiler does not heat water. If no preventive measures are taken, then very soon the boiler will have to be completely disassembled and deposits removed mechanically.

Only a timely one can help this trouble, and it should be done regularly, especially if cleaning and softening filters are not installed in front of the boiler. For washing, special chemicals, but they should be used with great care, since they are equally destructive to lime deposits and to the material from which the heat exchanger is made. It is best to invite a specialist for this purpose.

For safe and effective work gas boiler, preventive maintenance is recommended. It is advisable to do this regularly before the start of the heating season; you should not wait for the situation when the boiler does not heat water. This approach will ensure its long service life and economical operation. Overhaul is carried out as necessary by an employee of the service center - it is strictly forbidden to do this on your own.

Vaillant boilers are particularly reliable and safe. Breakdowns of such complex equipment must be eliminated by the master. But, minor malfunctions can be removed on your own if you have a basic level of knowledge about the design of heating and heating boilers.

Most faults are indicated on the boiler display. Having a decoding of errors, you can figure out what is the reason for the boiler's failure to heat water. Where to start the search if the heating of water in the Vailant boiler does not work, and the indicator does not show an error, or can it be interpreted in different ways?

Vaillant boiler does not heat hot water due to blockages

This is one of the most common problems. Most often, the reason is the low quality of water - scale appears, nodes, filters and pipes become clogged.

If the flame does not light up in the boiler, start the test with the flow sensor. Finding this cylindrical fixture is quite simple. The flow sensor is located near the pump, it is to it that the wires fit. Two sensors are installed near the pump:

Pressure sensor in the heating system.
flow sensor.

The flow sensor looks like a small fan, it starts to rotate from the movement of water through the pipes. If the flow sensor detects the movement of water, a signal is sent to the automation about the need to turn on the gas and heat the water. If the flow sensor is clogged, water will flow but the fan will not move. Accordingly, the signal to turn on the heating is not received. There are two ways to solve the problem:

Do not rush to disassemble the boiler and try to "purge" the system first. Shut off the valve public water supply at home. Open the hot water faucet and let the water out of the system. Now the percentage of air in the pipes has increased. Start abruptly opening and closing the water tap directly in front of the boiler. These simple manipulations will help create pressure and clean the flow sensor fan from debris.
If "purging" does not solve the problem, it is necessary to open the boiler, unscrew the flow sensor and clean it manually.

If the Vailant boiler does not heat hot water, the secondary heat exchanger should be checked. It also tends to get dirty quickly. But, fortunately, it is easy to remove, clean and install back.

A clogged three-way valve can also cause the boiler to fail to heat water. And you can remove this node yourself, clean it and install it back.

Having bought a Vaillant boiler, be sure to check with the seller information about the places where the filters are installed. You can clean and change these components yourself.

Faulty pump

The heating of water in the Vailant boiler largely depends on the operation of the pump. To repair or replace this unit, you must call a specialist. But, you can independently check whether it is the reason for the boiler's failure to work.

Set the water temperature on the boiler to 0 °C and turn on the water heating mode. At this time, monitor the operation of the pump. If after 20 minutes of operation it does not heat up, then the problem lies in the pump.

The reason for the failure of the boiler to heat water may also lie in the elementary unscrewing of the bolts in the connection areas. Look carefully at the boiler diagram and check that all connections are tight. Perhaps a simple tightening of the bolts will solve your problem.
