Is it possible to repair an indirect heating boiler.

Do.it.yourself water heaters repair

During the operation of water heaters, several types of malfunctions can occur:

  • Ten was burned out, the water does not heat up;
  • The thermostat has deteriorated;
  • The magnesium anode spent its resource;
  • Large layer of scale on the heater and the inner surface of the boiler.

All these malfunctions, except replacing the thermostat, require disassembly of the water heater. Considering that there is no fundamental difference between the connection of accumulative water heaters of Ariston with various capacity and modification, the disassembly process will be the same.

It can be divided into several stages:

In what options you need to dismantle the indirect heating water heater

Glass strainer diagram.The magnesium anode in the accumulative water heater used for the catalyst in order to protect the walls of the tank and aggressive influences on the heating device from the rust of the walls, sometimes you need to change.

The service period of the anode is due to the qualitative properties of the water used in the storage water heater (it is recommended to put a specialized filter on the cold water supply tube), the operating temperature of the water, the degree of intensity of the operation of the water.

The ordinary period of use of the magnesium anode indicated in the instructions for the operation of the water heater of the electric accumulative will not be more than 6 months. When operating the water heater of an electric accumulative in light mode, the magnesium anode will most likely last without a replacement of 1-1.5 years.

Together with the change of the anode, to prevent Vodogrey, you should carefully clean the space inside the tank from the scale and rinse the walls.

The heating element must also be cleaned with special chemistry or ordinary iron sponge for dishes.

The additional need to disassemble the water heaters appears as a result of the accident, malfunction or reaction of the water heater of the electric accumulative to the original operational conditions.

Basically, the heating element fails.

The connection diagram of the water heater of the electric accumulative to the network.If the water from the water heater of the electric storage has a poor smell, yellow or brownish shade. this indicates corrosion and clogging of the tank. The fact of too long heating of water, the occurrence of loud foreign sounds in the working period of the shadow speaks of the same.

It is necessary to quickly disassemble the indirect heating water heater, form with a breakdown and eliminate it. In any case, it is necessary to thoroughly wash the indirect heating water heater and verify the cleanliness of both the walls of the accumulative and heating element of the tubular type.

If there is a leak in a storage water heater, you need to make sure of the reliability of a rubber waterproofing gasket. If there is a need to make a laying.

If the leak appeared as a result of the depressurization of the accumulative tank itself, it is impossible to eliminate this malfunction with its own hands. This may be a production marriage. then the indirect heating water heater must be replaced by warranty agreements.

Sometimes as a result of poor operation of the water heater of the electric storage, the walls of the accumulative tank can be rustled. In this option, the operation of replacing the accumulative tank can cost more expensive the new water.

The entrances and exits of the indirect heating boiler

The boiler is the equipment precisely indirect heating. No self.respecting manufacturer will name other products. Primarily water heaters, accumulative and flowing type, gas and electric. These are not boilers! The water heater differs in that without a spiral or burner, no work can do any work. Another thing is a boiler, it has a coil, and sometimes even two, for the circulation of the coolant. The heating element is built in the form of an option. (Cm. Also: how to replace the heater in a boiler with your own hands)

Here is a typical set of entrances and outputs of an ordinary boiler of indirect heating:

Drilling hole to empty the tank. Unlike what we have in water heater this element does not coincide most often with a fence pipe.

A good tone. to leave a hole in the air of the air in the area of ​​the tank ceiling, where you can integrate the crane of Maevsky. This will help to empty and dial a boiler.

There is no hole for the crane of Maevsky. In this case, it is built into the release of hot water recirculation. And the pump is connected to the input through the check valve.

The recirculation of the coil is usually connected to the boiler, solar collector or heating system. Where exactly, indicated in the instructions.

A separate bypass valve is built directly into the boiler wall, but this is a fairly rare case.

There are even two holes for the thermostat. for the upper coil and for the lower. This allows you to flexibly manage the work of equipment. But most often the thermostat is only one.

This is an approximate set of portals of an indirect heating boiler, and now compare it with an electric water heater, which is hung on the wall. There is only an entrance and output for water. It looks like this is a boiler? Well, we have already discussed the origin of the term. We recommend that you go to the site of some serious manufacturer, like Ariston or Bosch, and there to see what a boiler is and what a water heater is. Now about fittings. Immediately make a reservation that in this sense we use the terms from shipbuilding, so the reinforcement is in the broad sense equipment: pipes, eyeliners, taps, valves, valves and even pumps. Although the latter are more likely to relate to the units.

Malfunctions and their causes

An electric water heater is a relatively simple device, therefore there are only 3 types of faults, however, they can have different reasons.

1) The boiler does not heat the water or does it noticeably slower than the previous one:

Connection of the boiler to the energy.dependent boiler

When used with power.dependent heating equipment, the boiler needs to provide a priority supply of the coolant. The easiest way that allows you to achieve this goal is to install a tank above the level of radiators. that is why wall models are usually used in such situations. The optimal location of the wall boiler suggests that its lower part is located at least slightly higher than the level of the boiler and heating devices.

Of course, with flooring devices, such a water heater is also able to work, but the water heating will be slow and inferior. At the bottom of the tank, the water will not be able to warm up to the end (its temperature will be at the same level with the temperature of the liquid in the reverse pipeline), so the total volume of hot water will be reduced.

The circulation of the coolant in energy.dependent systems is carried out naturally. To increase the efficiency of the system, you can put a circulation pump into it, and if there is electricity, water will constantly warm up. If desired, you can do without a pump. for the normal supply of the coolant, an increased diameter compared to the pipes of the heating contour to the water heater.

Hard of a solid fuel boiler with an indirect heating boiler

The connection of the water heater with a solid fuel boiler solves two problems at once:

Due to the fact that such a system on the battery is located a thermostatic valve, comfort is increased. But there is a danger of overheating of the boiler. The same threat occurs in case of interruption with energy supply. If a boiler of an increased capacity is installed, this process does not pose any danger. Because excess heat is consumed on water heating in a water heating tank. Accordingly, for the normal operation of this system you need a boiler with natural ventilation.

One of the binding options for a solid fuel boiler with a boiler watch in the next video.

Methods and tools for washing the boiler

Cleaning technology is not difficult. After disconnecting the tank from the feeding of the CVS and the drain of water, the internal parts are washed through the revision hatch, under the pressure with the help of the hose. Subject to regular maintenance and the availability of a system of fine filtration of this measure will be enough to prevent the formation of scale.

If the described cleaning method is not effective and visually visually visible the presence of calcium deposits, special tools will be required to clean the indirect heating boiler. Ready.made reagents sold in household chemicals and construction supermarkets are considered effective. If desired, you can make a flushing liquid using the ingredients present in almost every kitchen: citric acid or vinegar.

The bay in the tank means for chemical cleaning in 80% of cases will be able to completely get rid of the scale in the BKN, without disconnecting and without disassembling it. It is enough to block the water for a while and continue to follow the recommended order of the operation when washing:

  • water supply tap is blocked;
  • the tank is empty by a third;
  • The hose is connected to the drain fitting;
  • pour reagents;
  • For another free end, a funnel is put on for convenience, and before pouring the product, the hose is raised so that it is above the lower water level in the indirect heating tank.

After filling the tank with chemical reagents, the container is again filled with water and allowed to stand for 30-40 minutes. After that, the boiler is launched and the heat exchanger is heated to 40-45 ° C. Wait for another 1 hour. Fill out and lower the water twice.

After washing and performing maintenance, it is recommended to put back on the system. The water heater creates pressure above the worker, indicating the presence of leaks and loss of tightness with a tightness. Checking will help to identify a malfunction in a timely manner.

SNiP 3.05.01-85 “Internal sanitary systems” 4.6. The test of water heating systems and heat supply should be carried out with disconnected boilers and expansion vessels with a hydrostatic method of pressure equal to 1.5 working pressure, but not less than 0.2 MPa (2 kgf/cm² (2ati)) at the lowest point of the system.

How to rinse the boiler from scale

There are several funds capable of removing deposits. Not all scale will go away with the help of reagents and acids. With prolonged absence of full maintenance, the heat exchanger is overgrown with calcium deposits so that they can be eliminated only with mechanical or hydraulic cleaning. Work is carried out at home using a flushing pump to remove the scale, or in the service center (a boiler is required).

Equipment for chemical washing is divided into two classes: household and industrial. A flushing pump, regardless of the class, is expensive, which makes its acquisition for servicing 1 boiler economically inappropriate. At the same time, to achieve the same cleaning results, just a reagent will not work inside the tank. The pump makes it possible to rinse the coil qualitatively.

For service use finished chemical compositions or folk recipes. Proved its effectiveness application:

  • Sulfaminic acid. is part of specialized means for rapidly cleaning the scale on elements of the heating system and hot water supply. The peculiarity of use is that for dissolution in water, a chemical must be heated at least to 60 °. Costs sulfaminic acid (produced in granules) cheap. The bag will cost about 150-200
  • Citric acid is a folk remedy, effectively with a moderate scale. If desired, you can replace with vinegar. Washing the boiler with citric acid is effective only with regular servicing the boiler. When processing the internal elements of the water heater, every six months it will be possible to completely prevent the appearance of scale.
  • Specialized tools. advantage: careful effects on processed surfaces. For the maximum effect, it will be necessary to carefully observe the proportions of the mixture specified in the instructions for use.

The recommended dosage depending on the chemicals used is indicated in the table:

Means Problem Dosage
Lemon acid Scale 150 g per 1 liter of water
Vinegar Scale 200 ml per 10 l of water
Antin.Nakipin Scale According to the instructions on the packaging
Hydrochloric acid Rust With a concentration of 3 % 10 g per 1 liter of water
Specialized funds Knip and rust According to the instructions on the packaging

How to rinse the smell boiler

After 1-2 years of intensive operation, an unpleasant aroma of hydrogen sulfide appears. The smell is present only when using DHW, exceptionally hot water smells.

To eliminate the smell, just rinse and clean the heating element and the tank will not be enough. It is necessary to detect the reason why the water goes out and eliminate the malfunction.

possible, repair, indirect, heating
  • Accumulated bacteria-the temperature of water heating 30-40 ° C is optimal for rapid propagation of various pathogenic microorganisms. For prevention, it is necessary to warm up water to 70 ° at least once a month, with a built-in electric heating element up to 90-100 °.
  • Magnesium anode. the device prevents the appearance of scale, affecting the water and internal elements of the boiler with an electric shock. Over time, the rod decays, which leads to the appearance of an unpleasant aroma. You can eliminate the smell of hydrogen sulfide only by replacing the magnesium anode, or by changing it to titanium.

Further maintenance after eliminating the malfunction does not require attracting complex equipment or special chemical reagents. To rinse the boiler from the smell of hydrogen sulfide, you can use any detergent. After re.filling the tank with water, BKN is turned on at full power by approximately 1 hour. The smell should completely disappear.

How to rinse a boiler from rust

The surface of the tank is protected by enamel or its derivative, glassolmer. Rust in the boiler indicates that damage is present in the protective layer. During maintenance, the degree of malfunction is determined. Based on the condition of the inner surface of the tank, repair work is carried out.

Indirect heating. what is it, the principle of heating

There are only two methods of heat transfer:

  • The first, characterized by high efficiency and dedication, direct heating principle. This method is used in heating boilers to heat the coolant. A coil with a circulating liquid is located directly above the burner or a furnace camera. In this way, electric boilers, solid fuel and gas boilers, running gas water heaters heat water.
  • The indirect method of heating is the use of energy from the already preheated coolant of the heating system, for the needs of the hot water. Secondary heat transfer occurs. The fundamental scheme of work implies the following energy transfer chain: heat generator heat carrier hot water supply. It is this principle of operation that distinguishes an indirect heating boiler (BKN). The water heater is connected to the heating system and provides the needs of the hot water using the energy of the coolant.

What is the boiler for, where and how it is used

The main purpose of the BKN to ensure the needs of a private country house in hot water supply. The water heater can also be installed in an apartment having autonomous heating. In an apartment building, it is more difficult to do this due to a limited useful area. For the hot water heater is selected with a capacity of 60-100 liters.

possible, repair, indirect, heating

An indirect heating boiler is needed to ensure hot water supply from the heating system in which water heating was not initially laid. BKN is effective in the following cases:

On the Internet you can find recommendations for connecting the BKN to the underfloor system system. The purpose of such a solution often is to reduce the temperature of the heating of the coolant. BKN acts as a buffer container that controls the temperature. In fact, in the system of warm floors you do not need a boiler. For the leveling of heating, the knot is installed and the rowing.

How to eliminate malfunctions on an indirect heating Hajdu

I mounted the Hajdu AQ IND SC 200 electric water heater, but the liquid does not flow from the safety valve during the heating from the safety valve. Is it correct?

The check valve is used to drop excessive pressure. If the excess pressure in the eyeliner’s eyeliner is above the prescribed, the valve pulls cold water. If the fluid pressure rises when heated to the maximum permissible mark, hot water flows.

How recommended to disassemble, dismantle and clean from Nabi Ten in an indirect heating Haida 200 (floor)? He began to heat up worse.

First you need to remove the lid. There you will see an electric heating element. Unscrew the nut, stick it into the tank and carefully clean it. Then it is required to replace the magnesium anode. Run the tank from the inside. Collect all the components in the reverse order. The bolts need to be tightened with caution so that the hairpin of the heating element does not tear off.

When checking, I revealed that the heater is faulty. He has no heating. I want to change it myself. Someone can say how to do it right?

It is required to turn off the device from the network. Turn out the bolts and dismantle the electric heating element. Insert a new one and wash the tank with a stream of water. Wait a bit while it dries. Installation is made in the reverse order.

There was a breakdown of BKN. Completely stopped turning on, although there is a stabilizer that controls the voltage difference. The device in the work is almost two years, and there were no questions. And suddenly two days ago he spontaneously turned off when heated water. The RCD is constantly triggered, so it does not work to establish the cause of the failure in the work. It operates only a few seconds and turns off again. How to find a malfunction?

The device has a breakdown on the ground. Perhaps the electric heating element failed. If the water has great rigidity, then lime plaque and scale are formed. In this case, it is recommended to carry out the maintenance of the unit in a timely manner. Operate without a protective shutdown carefully, because the sheathing can beat.

The heating element was recently replaced, and after that the thermostat does not include. When you press the button, it is not fixed and moves back. Unit capacity 100 liters. What broke?

Presumably, the problem in the thermostat. It should be replaced.

Hajdu AQ indu capable water heater. If you stick a fork into a socket with a grounding contact, the RCD clicks, and electricity turns off. If you turn on the outlet without grounding, the device functions without problems and there is water heating. There were no such problems before. Explain what the reason is?

We recommend that you first diagnose the RCD.

Electric boiler for 150 liters. When you open the crane, hot water flows as if with air. The unit is served every year, the protective valve is in order, the flange sits tight. Due to which air appeared? He also makes noise with the sound of a boiling teapot. Tell me, it has grown a scale on a heating element?

If the temperature is high, the water with an excess of heating could be transformed into steam.

Why the device cannot give satisfactory pressure for hot water? How to fix?

Probably the device has nothing to do with. Perhaps there is a blockage of a pipe that removes water from BKN. It is recommended to inspect and clean it if necessary.

Due to which the protective device for an electric heater with a capacity of 200 liters is triggered?

Installed BKN Haidu with a capacity of 200 liters a week ago. Hot water is available, although the boiler began to publish some unnatural knock, mainly during the opening of cold water in the tap. Tell me what can knock there there?

Most likely, the inner tank begins to compress and unclench from the flow of cold water inside.

Recently bought an indirect heating boiler with a capacity of 150 liters. Completed its connection, filled it with water, turned on the network but nothing happened. Temperature setting was made maximum, the outlet is in order. Removed the panel and found a box that has a button. When it presses it, EVN begins to work. If you push back, stops working again. How to be in this case?

This device. safety relay. When it works constantly, it may have any defects in the wiring or the protective relay itself has broken.

We connected at home a water heater Hajdu AQ 200. When a new heating element was put, for some reason, water from the tank stopped flowing, though the water heats up. What you recommend fixing?

It is necessary to check the safety valve, as well as check the pipeline and, in fact, the boiler itself, since there is probably clogging.

Just such a storage boiler works for us. When we set the temperature by 65 degrees, the device heats the water only to 40 degrees. Could you tell me what it depends on?

AMTROL INDIRECT WATER HEATER NOT WORKING

It seems that the heater or thermostat is damaged, and other problems may also be. A detailed diagnosis should be performed.

At the dacha installed the AQ Ind SC 150 boiler. Suppose we have a temperature of 50 degrees on the thermostat. Explain whether this is the limiting temperature of water warming in the tank or this is the standard temperature of the trumpet of heated and cold water?

Undoubtedly, this is the maximum temperature. The unit heats up to the specified temperature and then supports it.

They disassembled BKN, cleaned and collected back. After that, he did not turn off, always functions in heating mode. In case of strong overheating, it turns off for a long time until it cools down. I can’t figure out what is the reason?

We advise you to inspect and check the thermostat. It is probably the reason for the violation of the device.

Cumulative boiler Haida 150 floor. The temperature controller is at a minimum. At the exit from the electric heater, the fluid temperature reaches eighty degrees, but the heating instructions indicate up to 70 s in the operating instructions. During such work, the thermostat is turned on, and there is a violation of contacts in the electrocope. Which component is required to change and how to check the thermostat?

possible, repair, indirect, heating

The main violations of the work of the Drazice boiler and their diagnosis

I launched a boiler of indirect heating DRAZICE OKCE 200 NTR-2.2, only at the time of heating from the check valve does the liquid do not flow. So it should?

possible, repair, indirect, heating

A protective valve is needed to drop an excess of pressure. When the excess pressure in the eyeliner’s eyeliner is more prescribed, cold water flows from the valve. If the water pressure increases when heated to the maximum permissible mark, hot water flows.

How to disassemble, get and clean the electric heating element in the BKN Drazhitsa 160 liters? I started working worse!

First you need to remove the lid. Inside is a tubular electric heater. Unscrew the nut, pushing it into the tank and carefully clean it. Then it is required to replace the magnesium anode. Run the tank from the inside. Complete all the details in the reverse order. The fasteners must be tightened carefully so that the hairpin does not vomit on the flange of the tubular electric heater.

In diagnosis, I determined a problem in the heating. He has no heating. I decided to replace it myself. Someone can say how to do this?

It is necessary to de.energize the device. Unscrew the screws and dismantle the electric heating element. Install a new one and wash the tank with water pressure. Wait for to become dry. Installation is carried out in the reverse order.

There was a problem with the electrician. Completely disconnected, with all the fact that there is a stabilizer from the voltage difference. The unit in the work is about 3 years old, and there were no troubles. And yesterday he spontaneously turned off when heated water. The RCD regularly knocks out, and because of this we cannot determine the cause of the failure in work. It functions for a few seconds and reduces it again. How to find a malfunction?

The device breaks to the ground. Perhaps the heater broke. If the water has a lot of stiffness, then a plaque appears and scale. Therefore, it is recommended to regularly prevent the unit. Run carefully without a protective shutdown device, because the case can beat the case.

A tubular electric heater has recently been replaced, and the thermallane does not include this. When you press the button, it moves back. Aggregate volume 200 liters. What happened?

Presumably, a malfunction of thermorelele. It is required to change it.

How to Install an Indirect Water Heater on a Boiler | Ask This Old House

Drazice Okce 125 NTR boiler. If you include in the outlet with ground, the RCD is triggered, and electricity turns off. If you include in a socket without grounding, the device acts without question and warms the water. There were no problems before. Tell me what the reason is?

We advise you first to check the RCD.

BKN per 100 liters. When the crane is opened, hot water flows simultaneously with air. The unit is cleaned once a year, the check valve is operational, the flange is fixed tightly. Why could air appear? Still inside, noise similar to a boiling teapot. Explain, Ten is uploaded?

If the temperature has increased too much, the water with excessive heating can turn into steam.

For what reason the indirect does not give an acceptable pressure for hot water? How to eliminate the problem?

It’s not about the electric bower here. Probably closed the output pipe from the unit. It is recommended to examine it and clean it if necessary.

In which case, a safety device in a boiler with a capacity of 125 liters is turned on?

The reason for the operation of the protection device may be an increase in the permissible limit of current strength. This can happen with malfunctions of the tubular heater or thermal controller. The plaque of the electric heating element also causes the operation. Security devices. It is recommended to take turns diagnosing all parts.

Installed a boiler of indirect heating of a Drazhitsa for 200 liters a week ago. Hot water is present, but the electric heater began to publish an incomprehensible knock, mainly during the opening of a crane with cold water. Tell me why the knock is heard?

Apparently, the internal container begins to expand and compress when the cold water is supplied inside.

Recently bought an indirect with a capacity of 160 liters. Connected it, filled it with water, turned it on to the mains and it did not work. Temperature adjustment is set maximum, the outlet is normal. Remove the lid and saw a block with a button. When it presses it, the unit turns on. If you squeeze back, stops working again. How to eliminate the problem?

This button. Protection relay. If it is systematically triggered, therefore, some defects in the wiring occurred or the safety relay itself has broken.

We connected the DRAZICE OKCE 200 NTR 2.2 electric boiler at home. When the heating element was changed, the water supply from the tank suddenly stopped, despite the fact that the water heating occurs. What else should be replaced?

Perform a check valve, as well as inspect the water line and, in fact, the device itself, since blockage is possible.

Installed and connected the same electric water heater. If I set up a temperature of sixty degrees, it performs heating no higher than 40 degrees. Explain what this is connected with?

Probably damaged an electric heater or thermallane, but there may be other problems. It is necessary to perform a detailed diagnosis.

In operation, a similar electric heater. Suppose we do 50 degrees on the thermostat setting. I would like to know if this is the limiting temperature of the water warming in the unit or it is an average temperature of mixing heated and cold water?

That’s right, this is the maximum temperature. The unit heats up to a tuned temperature and then holds it.

They disassembled BKN, cleaned and collected back. After some time, he stopped disconnecting, continuously operates in heating mode. In case of high overheating, he stops working completely, until it cools down. I can’t understand what the reason is?

You need to inspect and check the temperature controller. Most likely, it is the reason for the failure of the device.

DRAZICE OKCE 160 NTR cumulative boiler. The thermostat is installed in a minimum position. At the exit from the device, the fluid temperature is 80C, however, in the operating instructions, heating 70C was noted. At the time of this work, the thermallane is turned on, and the contacts of the electrical circuit are damaged. What specific component is required to change and how to perform diagnostics of the thermostat?

General rules for making indirect heating boilers

We have already talked about stainless steel tanks from old washing machines. However, finding such a blank is not easy. An excellent donor can be a written.off propane cylinder for 100 liters. He does not hold pressure (therefore was written off), and as a water tank will still serve. Of course, the boiler from the gas cylinder should be carefully cleaned (especially from the inside) and painted with high.quality waterproof enamel.

Industrial equipment is not required for manufacturing. Enough “corner grinder” and welding apparatus. The upper part is cut off, then heating reinforcement is formed in it.

With free access to other materials, you can perform a heater at least from a sheet stainless steel. You can see how to make an indirect heating boiler with your own hands on the video (watch below).

Perhaps aesthetics suffer, but the quality and durability of the heater made, no worse than the factory.

  • We already know that in the warm season, when the heating boiler does not work, indirect heaters are not in business. In this case, an electric heating element built into the tank as a backup element will help.
  • Another option for obtaining hot water in the summer is to install the second heat exchange circuit connected to solar heating systems.
  • As a result, you can assemble a heating system 3 in 1. From the heating boiler (regardless of the type of fuel), from the electric heating element and from the energy of the sun. When there are two of their three sources of energy, you can still provide the dwelling with hot water.

Electric indirect heater

The use of the heater does not belong to indirect methods of heating, since there is a direct contact of water with the primary heat source. The exception is an induction water heater. The liquid receives energy as if virtually, without touching the internal thermal element. Actually, it is not in the design at all.

With your own hands, a flowing water heater is made on the principle of induction hobs. Only instead of a pot of water with water, a metal pipe is heated.

The main advantage of the system is that heating does not occur due to direct thermal contact with the source of electric energy, but with vortex currents. The losses for the heat transfer coefficient are minimal, the efficiency strives for 100%. At the same time, both the metal pipe and the liquid are heated directly (if it is sufficiently thermal). In addition, flowing induction heaters are significantly safer than boilers with a traditional electric heater: there is no contact of water with an element connected to the mains.

The disadvantage is obvious: for heating, a power supply is required. That is, the option of indirect heating with a wood (gas) boiler does not work. The premises should be electrified.

When to call a specialist

When the water heater stops warming water, it immediately becomes clear that it is faulty. However, sometimes this is noticeably implicitly, it simply regularly knocks out automation, the RCD is triggered, when contacting water, it is current. All this also indicates a faulty boiler. Of course, in most cases, you can repair the water heater with your own hands, but there are times when it is necessary to call a specialist.

There are breakdowns, which only a professional can fix.

Such breakdowns include the following:

  • The almost new boiler is emergency disabled;
  • The settings are constantly reset on the thermostat;
  • The RCD is constantly triggered;
  • Water heater flask flows.

It is worth noting that in the latter case, repair is rarely effective, it is better to purchase a new boiler. The replacement of the magnesium anode, of course, can be carried out independently, but it is better to entrust it to specialists by contacting the service center.

How to care for a water heater

The quality of the main water allows increased hardness salts. The concentration of magnesium and calcium salts for humans is precipitated on the surface of the heating element. The same layer of salts on the inner surface of the tank is not terrible. It increases the protective layer, becomes additional isolation. And the heater needs to be cleaned annually, since the sediment does not conduct heat, the element overheats and fails. In a sour solution of vital or citric acid, the precipitate is destroyed, and the element becomes pure.

As a prevention against scale, you can use preliminary softening of water before supplied to the water heater. There are special water.cleaning filters for this. Be sure to put a filter on the water supply line for removing suspended substances from the water with their direction to the mud.
