Gas boiler no hot water. The boiler does not warm or warm hot water: cause and solution. Why the boiler warms badly, does not dial the temperature

If Gas boiler does not warm water For hygienic or general technical needs, the problem can be solved by heating the required amount of fluid in a saucepan. Much more problems will arise in winter when the heating system is blocked. With a long lack of hosts, freezing system is possible. Subsequent restoration of its performance is associated with significant financial and temporary costs. To eliminate such negative situations, it is necessary to choose and apply a complex of effective preventive measures.

Design features of the bucki gas boiler (BAXI), Navain, Ariston

In any case, familiarization with the technique of this class and the peculiarities of modern models are useful. These knowledge will help you choose the hardware correctly, do not make mistakes during operation.

In household boaches buxi (BAXI), Navien and Ariston, gas, diesel and solid fuel are burned to heat the water, use electric fuel. To fully use the potential of energy resources, heat exchangers are improved. They make long ducts of complex shape to ensure long-lasting fluid in the working area.

A relevant trend is compactness. Manufacturers offer gas boilers with square enclosures of a relatively small thickness. Some models in their aesthetic characteristics perfectly deserve placement in a prominent place.

The following feature is the introduction of automated control systems. They control the combustion process, change the modes of operation, taking into account the readings of the temperature sensors on the street and in separate rooms. When overheating, the technique turns off without intervention from the user.

It is necessary to consider carefully when the bucksy gas boiler does not heat the water. This happens, for example, when the supply of energy resources is stopped. It is not difficult to do the appropriate check even without special training.

Circulation pumps, valves, other standard nodes and aggregates rarely fail. Their designs are designed for long-term operation without compulsory maintenance. There are no moving parts in electronic circuits. Their breakdowns occur due to marriage. When complying with the rules established by the manufacturer, the resource of modern gas boilers of heating is more than 10 years.

Hanging the electrical part of the equipment is capable of throwing voltages in the power supply. To eliminate such impacts, an external stabilizer is established. It is useful to check the grounding system. This set of preventive measures for this group of problems is exhausted.

It is much more difficult to ensure protection from the most common cause of breakdowns of gas boilers - scale. It is she who studied in detail in this article. When heating, calcium and magnesium salts are converted into a solid state. It is these impurities that clog the narrow technological holes in the heat exchangers. They also form a porous structure on the surface of electrical heating elements. With a significant violation of the normal removal of the heat of their housing is damaged.

To prevent the formation of scale and lime inside the boiler, it is advisable to install non-chemical filters (water converters), magnetic and electromagnetic, which will provide a long "life" of your boiler and uninterrupted hot water supply, as well as protect the heating circuit.

Such filters (scale converters), as the scrawl or MWS, do not use chemical reagents and replaceable cartridges in their work. Once by installing such a device in front of the boiler, you will forget about the problem of scale for many years!

Troubleshooting: Why does a gas boiler warm hot water?

If the gas boiler is badly warming up hot water due to clogging or breaking the tube in the heat exchanger, repair is needed. It is performed by replacing the failed node. Threaded connections are not used in this case, so it will be difficult to disassemble independently and the subsequent installation will be difficult. To create a high-quality connection, the soldering is better to invite an experienced master. A qualified specialist will provide the necessary level of quality, will provide written guarantees.

You do not just know about the problem. A layer of scale grows slowly, so it will not be possible to register a clear reduction in power. Foreign noise can be caused by the passage of sand pipes, other mechanical impurities. Technological holes are too small for visual inspection. It requires dismantling.

These information is explained why emergency situations of this type occur unexpectedly. To prevent their development in a more complex problem, you can equip the boiler equipment with a modern remote control system. Some manufacturers offer ready-made solutions in the form of an additional electronic unit and specialized software.

The appropriate application is loaded onto a smartphone. The advantage is the ability to remote change settings, checking the temperature sensors. If the gas boiler is not warming up hot water due to scale, the heat exchanger replacement is not enough. The same pollution reduces the inner diameter of pipes, narrow the ducts in radiators. Full cleaning system is needed.

This procedure is performed according to the following procedure:

Drain water drainage.
Wash all contours successively, or at the same time special solution.
It is used to clean the heat exchanger, if only clogged and can be operated further.
After assembly, the performance of the pressure system is checked.
Eliminate identified defects (cracks, loose compounds).

To remove calcium solutions, or aggressive chemical compounds are used. The duration of the standard procedure for one household object is several hours. Relevant corrections are made taking into account the real state of the system. Strong acids are capable of damageing metal parts, soldering joints of the dual-circuit boiler Ariston. For this reason, experienced brigades are taken to fulfill orders tool for repair.

An independent execution of such procedures is possible. But for many ordinary users it is not advisable for several reasons:

You have to acquire expensive equipment for pumping liquids to be used.
An independent selection of the optimal composition of the solution will cause difficulties.
During this procedure, there are no mechanisms for operational control of processes within the system of the pipeline. This increases the likelihood of breakdowns.
With personal execution of operations, official warranty obligations of a third-party performer will not be obtained. All problems that emerged in the future have to be solved at their own expense.

Additionally, it should be noted that the careless handling of aggressive chemical compounds can cause harm to health.

Preventive actions

Specialists of enterprises offering flushing recommend to make every heating season. It is combined with a common inspection of equipment. Periodicity is corrected taking into account the level of rigidity, the intensity of the operation of gas dual-circuit boilers (BAXI), other significant factors.

Such tips are really helpful. Regular cleaning will prevent more complex procedures. Simultaneous check will help identify problems in the early stages. However, it is necessary to emphasize the main disadvantage of this technology - it is capable of damaging the equipment. It is especially unpleasant if defects are shown during the heating season. Prove the fault of workers who made cleaning will be quite difficult.

Instead of applying potentially dangerous techniques, effective protective measures are used. They are based on modern water treatment technologies.

So that in the heating boiler Navien or Ariston did not form scale, it is installed in front of it. They dissolve during the passage of water flow, they create dense shells around microscopic particles of scale (at the first growth stages). After such a "modification", harmful impurities can join the walls and each other. They pass freely along the contour, removed into the sewer.

The second method is to replace harmful compounds sodium ions. This procedure is carried out using special resins. They are falling asleep into two major containers that work alternately. As contamination accumulated, flushing with an inexpensive regeneration solution from the cook salt is performed. Such equipment is used for the overall protection of apartments, cottages, other properties.

Next reason why the gas boiler does not heat hot water and its decisions, it is a protective technology that has appeared recently, although known for more than a hundred years. The fact is that only constant magnets were used to treat from scale. They lose their useful properties over time. Moreover, the effect of "addiction" was experimentally detected when calcium and sodium compounds cease to respond to appropriate effects.

Nowadays, the technique is improved! Today, electromagnetic converters with high frequency oscillation generators are used. With minimal energy costs (5-20 W per hour), they operate at a distance of up to 2 km along the length of the pipeline from the installation site of the booth heating boiler or protema. This technique retains initial efficiency throughout the service life.

Ultrasound can be chopped by screaming particles, eliminate old education. But this technology is rarely used. Like acids, it is able to destroy the structural components of the water supply system. It should also be noted the likelihood of harmonic oscillations in the sound range.

Membrane technologies provide a high level of purification from different impurities, including rigidity salts. But standard household settings are treated not more than 200 liters. liquids per day. This is not enough for the needs of the boiler of the heating of Wilant and hot water supply.

Features of various technologies for cleaning the boiler and conclusions

If the gas boiler stopped warming water, it is necessary to repair it. To extend the life of the heating boiler, the Buderus or Ferroli and the prevention of accidents apply different techniques. To choose the appropriate option, you need to pay attention to the following details:

Washing with aggressive chemical compounds does not eliminate the problem, but liquidates the scale already formed.
Polyphosphates pollute water, so such protection is used only for the heating contour.
Sodium compounds harmless (this is an ordinary, well-purified food salt). However, after appropriate processing, water will acquire a pronounced flavor.
Ion exchange fillers are sensitive to temperature, humidity, various impurities. It should be clarified by the requirements that are set forth in the official instruction of the manufacturer of the double-circuit boiler Navien.
To connect electromagnetic converters, you need a current source of the corresponding power. To ensure its continuous work in difficult conditions, autonomous emergency power schemes are used.

When determining the reason why the Navien gas boiler does not heat, or heats the hot water badly, it is 3 ways to protect the stiffness of water, the architectural characteristics of the real estate object.

Individual heating and hot water supply has long ceased to be something unusual. It is convenient and practical, moreover, it allows you to not depend on the pleasure of utility services. Well, if some kind of trouble suddenly happens, for example, it will be found that the boiler does not heat the water, then to eliminate the breakdown will have to be forces.

No, this does not mean that you should be armed with a tool and start repairing yourself - for this there are specialized companies providing such services. If the heating boiler works properly, but it does not heat the water, then experts will repair its repair, make the boiler setting according to your wishes, and if necessary. All work will be performed qualitatively and guaranteed.

Modern gas boilers are reliable and powerful heating devices that also perform the water heating function. They are successfully combined, it would seem incompatible things - unsurpassed efficiency and compact dimensions. But their uninterrupted work is possible only subject to regular maintenance, detection and eliminating the slightest faults.

Faults of heating boilers

Basically, large faults begin to manifest themselves during the heating season, when two contour of the boiler works - heating and water heating. It may happen that it does not start at all, or he is not warm enough. With the launch, the question is to be solved separately, well, if it does not heat the water, then the reason may be in clogging the heat exchanger. As you know, the quality of water in our systems is far from the perfect, moreover, few users install in front of the boiler. So the heat exchanger is clogged, the result of which is the bad work of the boiler.

Here are the most common malfunctions of gas boilers in the event of which he is weakly warming water:

periodically spontaneously turns off,
smoking me
does not develop sufficient power
noise
clogged
pump broke.

If it happened so that the gas boiler does not heat the water, then often the reason is to form a lime-plated heat exchanger on the walls, which as accumulated becomes very durable and not only reduces the water temperature, but also reduces the capacity of the boiler. The thermal conductivity of the scale is ten times less than metal, so it is not surprising that the water boiler does not heat. If you do not take any preventive measures, then the boiler will have to completely disassemble and delete deposits to the mechanical manner.

It can only help this misfortune, and it should be done regularly, especially if the cauliflowing and softening filters are not installed before the boiler. Special chemicals are used for flushing, but they should be used with great care, since they equally destructively act on lime deposits and on the material from which the heat exchanger is made. It is best for this purpose to invite a specialist.

Preventive maintenance is recommended for safe and efficient operation of the gas boiler. It is advisable to do it regularly before the start of the heating season, you should not wait for the situation when the boiler does not warm water. Such an approach will provide the duration of its service and cost-effective work. Overhaul is made as an employee of the service center - to do it on its own it is categorically prohibited.

Wilant boilers are distinguished by special reliability and security. Cleansing such complex equipment must eliminate the master. But, small malfunctions can be removed independently if you have a basic level of knowledge about the device of heating and heating boilers.

On the boiler display, most faults are indicated. Having a decoding of errors, you can figure out what cause the boiler failure to heat the water. How to start a search if the water heating in the boiler Vailant does not work, and the indicator does not show an error or can it be interpreted in different ways?

Wilant boiler does not heat hot water due to blockage

This is one of the most common troubleshooting. Most often, the reason is in low water quality - it appears, nodes, filters and pipes are clogged.

If the flame does not light up in the boiler, start checking from the duct sensor. Find this cylindrical adaptation is simple enough. The duct sensor is located near the pump, the wires are suitable for it. Two sensors are installed near the pump:

Pressure sensor in the heating system.
Duch sensor.

The duct sensor looks like a small fan, it starts to rotate from the movement of water through the pipes. If the flow sensor fixes the movement of water, the signal comes into automation about the need to turn on gas and heat the water. If the duct sensor is clogged, water will flow, but the fan does not move. Accordingly, the signal on the inclusion of heating does not arrive. You can solve the problem in two ways:

Do not rush to disassemble the boiler and try the system at the beginning. Discharge the valve of the total water supply at home. Open the hot water faucet and release water from the system. Now the percentage of air has increased in the pipes. Start sharply open and close the water crane directly in front of the boiler. These simple manipulations will help create pressure and clear the fan of the duct sensor from the garbage.
If "purge" does not solve the problem, you need to open the boiler, unscrew the flow sensor and brush it manually.

If the boiler Wilant does not heat hot waterYou should check the secondary heat exchanger. He also has a property quickly clogged. But, fortunately, it is easy to remove, cleaned and installed back.

The clogging of the three-way valve can also cause a boiler failure to heat the water. And you can remove this node yourself, clean and install it back.

Having bought the boiler Wilant, be sure to find out from the seller Places information in which filters are installed. Clean and change these components you can independently.

Faulty pump

Water heating in the boiler Wilant largely depends on the operation of the pump. For repair or replacement of this unit, it is necessary to call a specialist. But, you can independently check whether it is the reason for the boiler failure.

Install the water temperature of 0 ° C on the boiler and turn on the water heating mode. At this time, follow the operation of the pump. If after 20 minutes of work, it will not heat up, it means that the problem is in the pump.

The reason for the boiler failure to heat the water can be in the elementary unscrewing bolts on the plots of connections. Carefully consider the boiler device diagram and check all the connections are tightly adjacent. Perhaps simple twisting bolts will solve your problem.

In this video, the solution of your problem!

See to the end and you will not need to call a specialist.

Without boiler rooms in the climatic belts of Russia, do not survive. And this applies to the warmest districts, Sochi, Anapa and Rostov-on-Don. Winters still remain harsh and without heating people do not survive. Therefore, do without heating systems and hot water will not be exactly. And only boiler houses are able to provide the city. Today we consider the reasons why boiler does not warm 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 like steam and water. They may vary at location. If the house itself made a decision on the construction of its own boiler room, then a special room in the house can be accomplished. Or to the house under these goals an extension is made. One of the basic requirements when erecting boiler rooms is good ventilation.

If the boiler works with steam, then the quality of water purification, and then the pair is predictable very high demands. Therefore, to do on such boilers without a whole complex of cleaning installations will not be exactly. The electromagnetic softeners are also included here, which are very valued by boiler house employees today.

If the gas boiler suddenly ceased to warm the water, the reasons can be different, but most often when using water from central water supply without softening installations, the cause can be the deposits of a limescale. Moreover, solid and poorly eliminated. The table shows the possible signs of the cause of the boiler stops due to the scale formed.

Other reasons for stopping boiler are simpler. Maybe a piece of scale to get stuck in the pipe and block the normal operation, and the crack in the gas boiler can also contribute to the disconnection. But in these cases on the walls of the equipment, there will be no balance of scale. If there are no treatment facilities in the boiler room, then the root cause of course will be the rigidity of water. If the sewage facilities are standing, and the equipment check was recently, then, most likely, the problem is not in this.

In any case, if there is no cleaning in the system, you will have to urgently go to this reason and solve it. For boilers there are a number of devices that softening water that will suit:

Scraping;
Ultrafiltration and air conditioning for steam boiler rooms;
Ion exchange for economical consumers of gas boilers

It is a waste of everything, the process of cleansing 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 expensive. But the work of the boiler depends on the quality of the pair. Here they just work and membrane softeners to make water completely isolated.

Many consumers of gas boilers choose for the simple reason that it does not need to be careful and you do not need to spend on it. But the greatest advantage for the boiler equipment was and remains to be eliminated even in the most difficult places old lime deposits. Usually, to eliminate such residues, equipment must be unwound, soak parts in aggressive acid environments and to withstand them there and for two hours. But even after it is necessary to finish the surface with metal brushes or cleaners. If your gas boiler does not heat the water to the desired temperature, then the reason for the deposits of scale. The electromagnet makes all this work, not the surface of the surface, at the molecular level.

Water heaters are used as a primary or additional source of hot water supply in apartments and country houses. A complex device may fail for different reasons, breakdowns deliver a lot of household inconveniences and require urgent elimination. Consider in more detail why cold water does not come to the water heater, for what reason the pressure can decrease and why difficulties are arising from heating.

Water heater

Why water heater does not work

First of all, you need to deal with the cause of malfunction. Most often, the owners of water heating equipment are faced with the following faults:

The water pressure at the outlet of the water heating equipment decreases.
The boiler picks up water and heats it, but there is no water outlet.
Water does not enter the water heating capacity.

The boiler is a complex system consisting of a variety of pipes of various diameters, filters, valves and valves. The failure of any node can lead to improper operation of the entire system.

Boiler design

Here are the main causes of faults:

Deposition on the walls of pipes, parts of valves or insoluble carbonate salts valves (scale).
Fit rust particles.
Blocking water current bubble.
The failure of the valve or valve (parts encoding).

First of all, you need to find a problem node. To do this, detach details from the input and see, after which node, water will stop entering the system. When the problem area is found, you can start repairing.

Important! Any actions associated with the opening of the water heating device housing lead to the loss of the right to warranty service. Get started only if the warranty period has expired. Otherwise, it is advisable not to violate the runtime rules, but contact the service center.

Trouble-shooting

Finding a problem node, you need to proceed to restoring the boiler's performance. The procedure for actions depends on the specific reason that prevents the normal operation of the device. Consider the most common situations.

Clogging by scale

Clogging of water heater scale

Sypt is the deposition of insoluble carbonate salts on the walls of the water heating. It is found in teapots, washing machines, water heaters.

The amount of scale depends on the rigidity of water. In regions with rigid water, even over the year of the operation of the boiler for the number of salts, located on the walls, it may be enough to completely block the clearance of the pipes of the heating element or significantly narrow it.

If scale has caused the output of the water heating device, it is necessary to repair the following order:

Open and remove the protective cover from the water heater.
Unscrew the nuts holding on the place of the TEN and take it out.

Dismantling of Tan

To wash away from carbonate sediments of the wall of the boiler and Spiral Tan. The organic acid - lemon or oxalous, solid crust will help dissolve. Industrial means can be used - anti-vakipins. Soak item in acidic solution to free it from accumulated deposits.

Cleaning the Tan from scale

With the help of the tester, make sure that the Spiral of Tan has not burned due to the disorder of heat dissipation.
If the spiral of the mustache - assemble the device in the reverse order of dismantling.

If the Ten has failed, you will have to look for a new or buy a new boiler - you need to choose the most economical solution. If the repair requires large financial costs, it is more profitable to immediately purchase a new technique.

Failure of pressure reducer

The pressure drops of the incoming water in the system can range from 2.5 to 7 atm. To compensate for jumps at the inlet to the boiler, a special node is installed - gearbox. His task is to ensure equal pressure at the outlet of the boiler and from the crane. If it fell due to the failure of the gearbox - it is necessary to adjust its operation or replace the broken part.

Low pressure in the main water pipeline also leads to a drop in pressure at the outlet of the water heating boiler or in a flow water heater. Unscrew the hose and check the level of the pressure: if water comes from the main water supply system with a thin flowing or does not go at all - it is worth waiver, as the problem may arise due to repair work. If the pressure was not recovered for several hours, it is worth contacting the water volokanal.

Terms of thermostat

If the water leaving the boiler is not heated or not heated at all, the reason may be the failure of the thermostat - it is he who is responsible for maintaining the constantly high temperature. To diagnose, turn off the boiler power and remove the thermostat from the housing.

Press the terminal button.
Heat the copper tip of the thermostat. If the node is working, the button must turn off.
Clean the thermostat electrical chains using a tester.

Usually, the thermostat malfunction is caused by overheating protection. As a result of the operations carried out, the device must earn, and the problems will disappear after it is installed in place. If the tester shows the circuit break - you will have to replace the turntable thermostat.

Touching the mixer

If water leaves with sufficient pressure from the boiler, and the crane runs slowly, the reason lies in clogging the mixer with scale or rust. It will take to turn off the water, disassemble the mixers and thoroughly clean the filter mesh. It is also necessary to inspect all sealing gum and make sure that the masturbers work normally.

If water does not go to the boiler

If the described causes are eliminated, there is no water pressure, and the boiler can still be filled, the cause may be an incorrect connection (the introductory and output tube) or clogging of the mesh filtering gasket can be. Eliminate these faults. Easy: Unscrew the hoses, rinse the filter and collect everything back in the right order.

Water heater work scheme

Another cause of a malfunction is a breakdown of the check valve. It is installed at the entrance to the accumulative tank and does not allow water to return to the plumbing. It can also burst excessive pressure during overheating. Over time, the valve spring is clogged by particles of scale and rust, as a result, the valve jars. Eliminate the problem will help disassembly and thorough cleaning. If you do not manage to clean the item and restore it, you have to look for a replacement.

Having understood why the boiler can stop working normally and how to eliminate the most common malfunctions, it is worth staying on the prevention measures.

Most breakdowns can be avoided by performing simple care guidelines:

Do not overheat water. Less temperature - a slower forms a scale, leading to breakdowns.
In the design of many boilers, the use of softening cartridges is provided. Do not save on water mitigation, as it will help to avoid spending on repairs.
When departure for several days, turn off the device without merging the water. But to disconnect overnight to save energy - it is impractical due to the large wear of the electrical part.

Installing the gas boiler allows you to forget about cold water in batteries and cranes. Double-circuit models are able to simultaneously work for heating and hot water supply (DHW) of the room. But what if the boiler does not heat the water? If you are faced with a similar problem, our recommendations will help find the cause and eliminate the problem with your own hands.

The principle of operation of the boiler

To figure out the cause of the breakdown, you need to understand how the boiler works. Double-circuit devices "Ariston", "Baksy" and other models have several blocks. In the gas site, ignition and burning occurs, the water assembly is responsible for the supply of water and pressure in the highway. The chimney block displays combustion products into the street.

As soon as you run the boiler, the pump is triggered, which pumps water into the system. A gas valve opens. The liquid circulates through the heat exchanger tubes, and the burner evenly warms its body. Sensors control the heating process. As soon as the temperature reaches the given, the gas supply is turned off, heating is stopped.

When the temperature begins to decline, the sensors will send a signal to the control module - the heating cycle will start again.

When you open the mixer, the flow sensor is activated. It gives a signal to switching the three-way valve for heating DHW. When the mixer closes, the valve switches to the heating system. Some models are equipped with a "Quick Start" mode. Then the valve periodically switches, heats the first, and the second heat exchanger.

Why the boiler warms badly, does not dial the temperature

No hot water? For what reasons the technique does not work? Sometimes it's in external factors. Consider more.

The device works, but does not heat or light warms

Airlock. Check if the air in the batteries did not accumulate. Using cranes, remove excess air. If you do not have an air vent on radiators, then you need to install it. By adjusting its crap, you can lower the accumulated air in the system.

Also inspect the valve for a blockage. Most often, he is clogged with skidding.

Vomor in radiators. After cooling, shut water from the pipes. If it is strongly contaminated, run across the batteries until it flows clean.

Invalid connection. If a hot stream does not go, make sure that the diameter of the pipes corresponds to the instructions declared. Hoses are connected correctly, lock valves are mounted.

Low pressure in the highway. It is not enough to open the valve and the ignition of the burner. Fresh water.

The accumulation of scale in the heat exchanger. It can be noted that the technique heats the fluid for a long time, the batteries are weakly sink. Clean the radiator tube from deposits. To do this, the node is better to remove, but it can be done not in all models. Therefore, remove the casing, turn off the device from gas and water. Connect the tube from the pump to the heat exchanger from the pump, drive the cleaning fluid on the system. Special funds can be chosen in the store. Then rinse the part with running water.

Adding reagents to the fluid of the coolant helps reduce the formation of salts on the details.

When buying it is important to pay attention to the brand and the model of the boiler. For example, manufacturers "", "", "", "", "" prohibit the use of the reagent. It is recommended to install cleaning filters or use distilled water.

Antifreeze can be applied to models, "", "", "," "," ". But for each manufacturer, a separate reagent is produced.

Voro filter. Another reason for poor battery warming. The mesh filter is clogged with small garbage, so it is periodically removed and cleaned under running water. With a strong lock or wear, it is better to replace the item.

Invalid adjustment. Check the set values \u200b\u200bon the panel. It may be selected too low temperatures, so the gas does not heat hot water.

Problems with the work of the circulation pump. Overheating, the pump is turned off when the hot water is turned on. Its power may not be enough to normal circulation. Adjust the settings.

Battery design does not suit your equipment. Each construction has its own permeability and heat transfer. Incorrect selection leads to a decrease in heating due to system patency.

Non-compliance with the liner of the highway. The problem is characteristic of systems with natural circulation, which is ensured by compliance with the installation standards. According to the documents, the bias of pipes for each trafficphone meter should be at least 10 mm. No slope - no heating. The coolant is stored, batteries remain cold.

Gas boiler does not turn on, does not give hot water on the DHW

The main cause of troubleshooting is salt deposits. The greater the layer of scale in the heat exchanger, the worse conductivity. Water heats up for a long time, a thin little warm stream flows at the exit. Also a piece of scale could get off and overlap the passage to the mixer. What to do in this situation, we described above.

Problems with flow sensor. The part works on the principle of the fan, which rotates due to the flow movement. The sensor may not work when clogged. To clean up without dismantling, open and close the crane, which is located near the circulation pump.

If the procedure did not help recover, you will have to remove the sensor, clean and install in place.

Three-way valve malfunction. If the valve jammed or he broke, it will not be possible to switch the water supply from the heating system to the DHW. The cause of the problem could serve the detail, gas hose or filter. Spend all the elements.

The reasons for troubleshooting a lot. Determine what problem arose in your loop will help us with the signs described. Pay attention to the equipment and compare with the specified problems. If it is not possible to solve the malfunction yourself, contact a specialist.

During the operation of the two-kinth gas boiler, each user will face certain problems associated with the operation of the hot water supply circuit. These problems are inevitable. They always appear, regardless of the manufacturer of the boiler and from its heat exchanger, on the design features of the boiler; It doesn't matter whether the kittel is wall or outdoor. Often the boiler begins to warm the hot water or warm it at all. Especially when you use multiple points at the same time. Let's talk in this material how to get rid of this problem forever.

In any room where a double-circuit gas boiler is installed, be it an apartment, a country house or office, there are certainly there are several places that are water intake points: washbasin in the toilet, shower in the bathroom, washing in the kitchen. All these points are connected to the contour of the hot water supply of the boiler.

What happens when turning hot water at one point of the fence

A double-circuit boiler is based on maintaining a certain temperature in the hot water circuit. When turning on hot water on one of the points:

some time, cold water continues to go from the crane, which before its discovery stood in the pipe,
it turns on the heating of the boiler, and a certain time is required in order for it to be on the specified temperature,
after a few seconds, the heated water enters the pipe and starts movement to the point of the fence,
a few more seconds are needed so that hot water reaches the point of the fence,
an additional few seconds are necessary due to the fact that the received water seems to be too hot to the consumer, and it regulates the water supply by the mixer.

Thus, from the time of opening the hot water crane and until the start of water supplying a comfortable temperature, it takes at least a few seconds. The further the water fence point from the boiler is located, the more this period of time.

All this time, the user cannot fully use the water and it will be that the boiler does not heat normally hot water. It expects the moment of water receipt having a comfortable temperature. Meanwhile, water that is not comfortable for the user's temperature simply goes into the sewer.

Unproductive water consumption can be from several liters to a tent of liters depending on how far the water fence point from the boiler is.

What happens when it turns on hot water at the same time on two points of the fence

The scheme is complicated if during the use of hot water at one point of the fence, there is a need to turn it on at another point, for example: when the soul is on, the bathroom has the need to wash your hands in the toilet washbasin. In this case:

the speed of using hot water increases sharply, its flow increases,
a weak head of hot water appears;
the arrival of cold water in the boiler increases,
the drop in the temperature of the heat exchanger of the boiler leads to the fact that the temperature of the water at the first point of the fence ceases to be comfortable,
a few seconds are required to include automatic boiler for heating,
a few more seconds - to ensure that both users can use water with a comfortable temperature at two points.

All this time, both users cannot fully use hot water. She comes with interruptions. Unproductive water consumption, it is useless to flow into the sewer, increases dramatically.

What if one of the users turned off the water? In this case, hot water consumption drops sharply. On the heater of the two-circuit gas boiler occurs a leap of temperature. As a consequence, the temperature of hot water is sharply increasing on the point of the fence that continues to work. The user cannot fully use water, it goes into the sewer until automatics work on the boiler, and the water of the desired temperature will come to the user in stable mode.

Since such situations are repeated several times every day, the unproductive consumption of hot water increases with each day. It should not be forgotten about discomfort, which is experienced by users at the moments of unstable hot water supply.

Ways to solve the problem

The problem can be solved by methods requiring significant investments of funds, for example:

use with the boiler,
buying a new boiler with a built-in boiler.

However, there is a method of less expensive, but very productive - inserting an electrical cumulative heater in the contour of hot water supply. Moreover, for this purpose, any standard heater with a volume of 30 l is quite suitable, regardless of the manufacturer's company.

Use the water heater

The water heater embedded in the contour of the hot water supply acts as a buffer container. Its purpose is to equalize the temperature of hot water and smoothing the possible leaks of temperature. The water heater of the drive and the gas boiler heater is displayed on the same operating temperature.

Even in the case of the simultaneous turn on hot water cranes at different points of its fence, all users will first get water from the drive at first. The costs of time associated with the expectation of a comfortable water temperature are reduced. The unproductive water consumption is reduced.

The inclusion and shutdown of hot water supply at any point of the fence causes the water temperature drop on the outlet of the gas boiler. However, this water enters the lower part of the water heater, and when it leaves it out of the upper part, the temperature leap is completely smoothed.

Connecting a water heater through a ball valve allows you to go to the usual system of operation of the gas boiler at any time, which can ensure uninterrupted hot water supply in the event of a water heater breakdown.

The use of bypass jumpers with a crane in close proximity to the boiler makes it possible to eliminate the boiler from the hot water system. In case of finding a boiler for maintenance, the use of the existing water heater will ensure uninterrupted operation of the hot water supply system.

Use Expansion tank

In winter, when the boiler is involved in the heating circuit, any inclusion of hot water leads to what is turned off in order to turn on the contour of the hot water supply. In the summer, when the boiler is not involved in the heating circuit, each inclusion of hot water leads to the inclusion of the gas boiler.

Often, the user opens the crane of hot water in order to just rinse his hands. The boiler turns on or switches, hot water goes through pipes. But the user can simply not wait for it by moving his hands with cold water.

Meanwhile, frequent and useless inclusions and switching of the boiler "eat" its resource of work. Possible output - Installing a small expansion tank. It is installed in front of the water heater. If there is such a tank, at first after turning on the crane, hot water enters the pipe exclusively from the water heater due to the pressure growth in the tank. Thus, in the case of a short use of hot water, there is no need to turn on and switching the boiler.

Use Recycling pump

The optimal option is a water heater located in the immediate vicinity of hot water intake points. What he is closer, the faster the hot water will go into the crane, the more efficient it is used. If this option is not possible to install the water heater, then recycling pump is recommended.

The pump is installed on a segment between the water heater and the points of the hot water fence, providing slow motion of hot water through pipes. In addition, if you cut a heated towel rail on this segment, it will perform its own direct function at any time of the year, regardless of the work of the heating circuit of the boiler.

The effectiveness of the proposed method

With relatively small cash, the installation of a water heater, an extender and pump allows:

save up to 25 thousand liters of water a year if a family of four people live in the apartment,
use water comfortable temperature even in case of simultaneous operation of several water intake points,
reduce gas and electricity consumption,
extend the life of the two-kilt boiler.

Good evening all! After 4 months of operation of the two-king gas boys, he stopped warm hot water. Why? What is the reason? I assume that the boiler works on unprepared water and possibly "overgrown" by scale or rust. What advise the Lord?

Happy holiday, Irina! Beautiful photo. How I love mimosa! Did not have to choose, the hand itself reached for

The most frequent cause of the breakdown of the boilers, it is screamed. Most likely, you have a heat exchanger of the boiler scored screamed and does not warm it. Solution - install specials. Filters. For example, magnetic or electromagnetic. Put in front of boilers and work for many years without requiring maintenance. See manufacturers Kema (Moscow) or Aquares (Ufa). Good luck!

Yes, most likely your two-round boiler was covered with science. That is why he stopped warm hot water! Why? Hard water! What to do? Install the filter. For example, ion exchange or electromagnetic.

Wilant and Bakci boilers are distinguished by special reliability and security. Cleansing such complex equipment must eliminate the master. But, small malfunctions can be removed independently if you have a basic level of knowledge about the device of heating and heating gas double-circuit boilers BAXI, ARISTAN or NAEN. On the display of the bucki double gas boiler, most faults are indicated. Having a decoding of errors, you can figure out what cause the boiler failure to heat the water. How to start a search if the heating of water in the two-kinth gas boiler boots or vailant does not work, and the indicator does not show an error or can it be interpreted in different ways? A gas boiler does not warm hot water. Why? Cause? Boiler double bucky (BAXI). If the double-circuit gas boiler Vailant, Buckuck, Arista or Navain does not heat hot water, you should check the secondary heat exchanger. He also has a property quickly clogged. But, fortunately, it is easy to remove, cleaned and installed back. What is the reason? Why is this happening?
