Do-it-yourself Ariston water heater repair

Ariston Academy names the main mistakes in connecting an electric storage water heater, which can put the tank in danger. Replacement of the original valve with an average check valve, complete exclusion of the specified element from the piping. In order not to repair the Ariston water heater with your own hands on an ongoing basis, as well as purchase an Ariston water heater on your own, again and again, know a couple of simple rules, which we will talk about casually below. The features of Ariston water heaters are limited by the lack of flow-through models. There is a magnesium anode everywhere, the tank is made of steel. It’s useful to remember when you get the hang of doing your own Ariston water heater repair.

How are Ariston water heaters classified?

Drain the water from the tank.

Thermostat failure

The capacity will initially increase by a couple of liters, adding extra 30 seconds of washing in the shower, then the tank will burst and begin to leak water through the cracks.
Just a cloth, hands, soap. If it leaks, replace the gasket. After connecting to the water supply, the tank of the device is filled with cold water. It is necessary to clearly mark the mounting location of the water heater using a level and tape measure.

Next, the failed parts are replaced and the surfaces are cleaned of salt and lime deposits. Everything is simple, with obvious changes in operation: Strange hissing during operation. It would be useful to install a fuse that protects the spiral from combustion. Then this tap must be closed again. The conservation and subsequent activation of the boiler deserves special consideration. ARISTON water heaters. Installation and installation

Main types of faults

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

The heating element has burned out, the water does not heat up;
The thermostat has deteriorated;
the magnesium anode has used up its resource;
a large layer of scale on the heating element and the inner surface of the boiler.

All of these faults, except for replacing the thermostat, require disassembling the water heater. Considering that there is no fundamental difference in connecting Ariston storage water heaters with different capacities and modifications, the disassembly process will be the same.

Getting rid of leaks

If you notice that water is dripping from the boiler, it is not always possible to repair it yourself. It is good if the cause of the leak is wear of the seal on the flange. In this case, the gasket must be replaced with one of the same size, which will allow the damage to be repaired. Things are much worse if the water heater is leaking due to wear and tear on the tank itself. Some people advise gluing or soldering the holes, but, as practice shows, after a short period of time you will still have to say goodbye to the boiler, because. Such leak repair methods are extremely short-lived.

Master class on fixing leaks

That's all I wanted to tell you about repairing the boiler yourself. We hope that now you know what to do if your electric water heater leaks, does not heat water well, or does not work at all. There are not many problems with these devices and you can get rid of them with timely system maintenance. At least once a year, inspect the check valve and clean the heating element so that malfunctions avoid you!

Required Tools

There are several reasons why you need to disassemble the equipment:

warm water is cloudy, there is a foreign odor;
scale flakes are visible;
when touching the body, a current discharge is felt;
when the tank is turned on, the machine is activated;
the device takes a long time to heat water or does not heat up at all;
water is slowly rising;
weak pressure of warm water when exiting;
the housing is leaking.

To disassemble and subsequently assemble the Termex, Aquaverso es30v, Oasis water heater, you need to use the following tools:

Screwdrivers - straight and Phillips.
Wrenches. You need a universal gas wrench or a socket wrench - horn size - 22; 14; 10; 8, for some models you may need 32, 24 mm.
Slotted screwdriver.
Hexagon 4 mm.
With pliers.
Indicator screwdriver.

Troubleshooting instructions

Ariston boiler repair consists of a series of actions that must be performed sequentially. First of all, before carrying out manipulations, it is necessary to determine the specific problem. For example, if you need to replace a safety valve, thermostat or relay, there is no need to dismantle the device. It is necessary to disassemble the device and drain the water during maintenance or replacement of a burnt heating element. Disassembly is carried out in several stages:

First you need to disconnect the product from the network;
drain the water;
dismantle the flanges to get to the inside.

These are standard manipulations that should not be neglected. There have been numerous cases when home craftsmen, having forgotten to disconnect the device from the power supply, received electric shocks of varying severity. Having de-energized the device, you can begin dismantling it:

Unscrew the cover secured with screws.
Take photographs of the location of the wires and bolts so that nothing gets mixed up during assembly.
Carefully disconnect the three-core cable. The first two wires - phase and zero - are connected to the thermostat. Then the latter must be carefully removed.
Then you can start draining the liquid.

The most vulnerable parts

Today, Ariston is the top three world leader in the production of equipment. The kitchens of this company are equipped with a range of household appliances - from a refrigerator to a dishwasher. In Russia, the brand gained popularity in the late nineties; its service centers can be found in all major cities.

In this video you will learn how to drain water from a water heater:

The peculiarity of electric boilers is their modern design, functionality and affordable price compared to analogues. The developers place special emphasis on the safety of their products during operation: the devices are equipped with various protections that turn off the device in the event of power surges, overheating, or lack of water supply.

Despite their reliability, water heaters are vulnerable to hard water and power failures. According to experienced experts, the weak points of Ariston water heating devices are tubular elements, magnesium anode and check valve. You can fix these simple faults yourself with a minimal set of tools. The products are characterized by a standard assembly scheme, so repair and maintenance work is not particularly difficult.

About the brand

In the mid-40s of the last century, Aristide Merloni launched the production of electric water heaters under the Ariston (Successful) brand. The name fully justified itself, and after some time all the sons of the entrepreneur successfully entered into a similar business, and the youngest, Vittorio, inherited his father’s company.

The Ariston company today is one of the top three in terms of global sales of household appliances, and Ariston brand kitchens are sold with already built-in basic household appliances from the refrigerator to the dishwasher. In Russia, this company became famous in the late 90s of the last century, and now almost every major city has its service center.

Geyser Ariston Fast EVO 11b

Vladimir Excellent speaker at an affordable price, with electronic ignition and flame modulation. But the presence of modulation does not eliminate the need to regulate the temperature - sometimes you need to adjust it yourself, without relying on the column (most often in winter and early summer). These are, of course, trifles, since otherwise it is almost flawless. It has been hanging in the house for a year and a half, does not leak, ignites softly and without popping, and ignites normally with minimal pressure. By the way, the temperature is very easy to adjust; the required value is easily selected using the built-in indicator. We can recommend it to anyone who wants to get trouble-free hot water supply at home.

Advantages:

The performance is sufficient for the simultaneous operation of two cranes;
Lights up even with minimal water pressure;
There is a heating limitation, the output temperature is stable and does not fluctuate, like on cheap Chinese speakers.

Flaws:

Some very simple appearance, like a monolithic concrete slab. It feels like something is missing;
When the flame is small, a whistle appears, and it disappears completely if the flame is on full.

Design and principle of operation of the Ariston water heater

Often the malfunction manifests itself as a clogged radiator.

Before you begin replacing the heating element, you must disconnect the device from the power supply. Safety valves are installed at the inlet and outlet; they are open if the water heater is turned on and closed if the device is turned off. Connection to hot water is also made through a shut-off valve and adapter.

There is a magnesium anode everywhere, the tank is made of steel.

Remove the flanges and gain access to the inside of the water heater. The thermostat is designed to disconnect the water heater from electric current when heating water to a set temperature

Features of repairing Ariston water heaters Ariston: review of faults and do-it-yourself procedure The Ariston company has long been a respected manufacturer of household appliances and has an established positive image in our market. Remove excess debris at the bottom of the tank, visually inspect the rubber seal, if everything is in order, then do not change it - it is very expensive, and it is very difficult to get a new one. Remove the flanges and gain access to the inside of the water heater. Use original anodes from the manufacturer for each individual Ariston water heater model.

An anode is located inside the tank to protect the heating element from scale. In the morning, the couple will fill 2 baths, mixing hot and cold streams. Often, the anode, as noted above, is installed near the heating element. Take a lighter or candle and heat the thermostat bulb.

Causes of breakdowns

But at this time the sealing gasket must be removed; it loses its elasticity in the solution. To remove the protective cover and disconnect the wires, you must first draw a connection diagram or photograph it, which will facilitate the reassembly process.

Hello! I would like to ask you for technical advice. I have been using an Ariston brand storage water heater, model ABS PRO ECO 80V (topmost photo on the site) for 8 years now, I am satisfied with the product. But time takes its toll and a certain problem has arisen, namely, the next time the temperature sensor is triggered (if the period between switching on was 1 hour or more), the entire display on the front panel blinks and frequent clicks under the plastic casing of the indicator panel are observed for about 10 minutes, then the frequency of clicks gradually decreases and the device turns on. It should be noted that if the period between the activation of the temperature sensor is short (15-20 minutes), the heater turns on without problems. But during the period of frequent clicks, it seems as if some relay cannot be pulled in, then gradually magnetizes and closes the contact, the heater starts working.

Quality and weaknesses

Ariston water heaters have a stylish modern design, excellent functionality, and differ from analogues from other manufacturers at a reasonable price

Developers pay careful attention to the safety of products during operation: the units are equipped with various protections for all occasions, turning off the product in the event of a power failure, overheating, or lack of water supply

But this reliable equipment suffers from the hardness of our water and quite frequent changes and surges in voltage. The weakest points, according to experienced craftsmen, are tubular-type heating elements, a magnesium anode and a check valve. These very simple breakdowns can be fixed with your own hands if you have the necessary minimum tools. The design of the product has a standard design, so prevention and repairs are not difficult.

Recommendations for home repairs

Regardless of the nature of the breakdown, before starting repair work, you first need to turn off the power supply, remove the protective cover, disconnect the wires, pipes and drain the water.

Wall-mounted models are usually removed from their brackets. The protective cover, which hides the connection point for electrical wires and the mounting of heating elements, may have a different position depending on the model.

On horizontal devices, this element is usually located on the left, on vertical heaters - at the bottom, and on small models - in front. In some devices, you first need to unscrew the main mounting bolt located in the center. Sometimes this element is hidden under a decorative sticker.

After this, you need to carefully remove the thermostat, and then remove the temperature sensor tubes. They must be handled very carefully. If the integrity of the temperature sensor tube is damaged, liquid filler will leak out of them. As a result, you will simply have to throw away the water heater and buy a new device.

The temperature sensor tubes highlighted in blue should be protected from any deforming influence; if they break, the entire device will have to be completely replaced

If the thermostat of a household water heater has become unusable, it will have to be completely replaced. The models of such devices are varied; it is best to choose an analogue with a similar device and characteristics

If there are stickers on the case that indicate the serial number, they must be preserved, even if they interfere with the maintenance and repair of the product. This may affect the manufacturer's fulfillment of warranty obligations, as well as make the work of service center employees easier.

Prevention as a way to avoid problems

Not only home owners provide themselves with autonomous hot water. More and more residents of apartment buildings prefer to install instantaneous or storage water heaters. There are 2 reasons for this unconditional popularity: interruptions in hot water supply, especially in the off-season, and the high cost of hot water supply.

Italian Ariston boilers have been popular for several years now. They are distinguished by high quality, reliability, and long service life if used correctly. Nothing lasting has been invented yet, and therefore sometimes you have to do repairs yourself.

And although a water heater is a rather complex device, its regular cleaning and maintenance can be done independently in just a couple of hours. The main thing is that before you start the actual work, understand not only how the equipment works, but also how to disassemble it correctly.

The most important thing is to completely drain the water from the boiler. There are 2 pipes installed on the lower part, through one of them water flows into the boiler, through the second it is drained.

Since high-quality drainage is the key to a successful outcome of the entire operation, we will dwell on it in more detail.

The procedure depends on the features of the particular model - with a trigger, a tee or through a check valve.

The most demanding model is considered to be the one in which a reinforcing tee is built between the pipe and the valve. You will have to unscrew it with an adjustable wrench and drain all the water.
on those models where there is no tee, but there is a trigger - a jumper on the reverse valve. You can bend it, fix it and wait until all the water drains. This process usually takes 1.5-2 hours.
The simplest and therefore most effective way is to unscrew the check valve counterclockwise. Before doing this, connect the hose to the water outlet pipe and drain.

Attention! All work is carried out only after the water heater is disconnected from the power supply!

How to properly disassemble a boiler?

For those who don’t have time to read, we have prepared video instructions on how to disassemble an Ariston water heater. Here you will learn about the features of installation, connecting to pipes, cleaning, etc.

Required Tools

screwdriver;
pliers;
knife;
hose for draining water, matching in diameter with the return pipe;
replacement anode;
a special cleaner for cleaning heating elements; you can also use a concentrated solution of citric acid.

Let us repeat once again, all work on disassembling the water heater is carried out only when it is completely de-energized.

Procedure

Remove the cover from the bottom of the boiler by unscrewing the bolts around the perimeter.
Drain the water as indicated earlier (it’s easier and faster to drain through the pipe).
There are several bolts on the inner casing; they need to be unscrewed (don’t forget to replace the bowl, there is still about 15-20 liters of water left in the system).
Over time, the bolts become “baked” and are very difficult to unscrew. If this happens now, it is better to remove the boiler from the wall, lay it horizontally and then unscrew it. By the way, the tightness of the twist indicates a high-quality assembly.
Very carefully pull out the electrical unit. But in such a way that the rubber gasket remains intact - it is very easy to tear or deform. At this stage it is advisable to take photographs of everything you do. Then you will have to assemble it in reverse order and then your photos will be very useful.
If necessary, replace the anode with a new one, and soak the heating element in a solution of citric acid. The minimum time is a day. After 24 hours, take any non-sharp object with a narrow end and carefully remove the scale from the heating element. All this should be done only if the cause of the breakdown is a burnt-out heating element or the need to replace the magnesium anode. How to find out what exactly is preventing the operation of the unit is further in the text.
The electrical unit of the boiler is treated using a cleaning composition. Plaque can be removed with a dry, hard sponge.

The device does not heat the water - if you are sure that the socket is working and there is electricity, the fault lies in the heating element.
The water heats up very slowly - the magnesium anode needs to be replaced.
During operation, a distinct but dull hissing is heard - excessive scale and deposits on the heating element.

What to do

Ariston water heater is leaking, what should I do?

None Typically the tank includes the following functional units:

heating element for heating water;
thermostat for controlling and monitoring the heating temperature;
relay that controls on/off the heating element;
magnesium anode that protects the tank from corrosion;
a safety valve that reduces the pressure inside the tank when water is heated;
electronic control unit (simpler models are equipped only with warning lights).

Good to know: to heat a cube of water by one degree, 1.167 kW/h of electricity is required; if the supply water temperature is 17 degrees, then to heat it to 65 degrees you will need to spend about 56 kW/h without taking into account the heat loss of the boiler and pipes.

Replacing the thermostat, relay, and safety valve does not require dismantling and disassembling the tank. Otherwise, you must drain the water from the tank. A heating element that has become unusable will require disassembling the boiler, but the Ariston water heater is very easy to disassemble.

You can do this yourself at home, following a certain sequence: When draining the water, you will have to suffer if this was not taken care of in advance during installation: two taps must be installed under the water heater - at the inlet and at the outlet of water from the tank.

And then the usual physics - when you open one tap, water will not flow from the tank until air takes its place. Therefore, a second tap is necessary to supply air to the system.

Expert advice: in order for the Ariston boiler to serve without repair for many years, it is necessary to carry out preventive cleaning once a year and limit water heating to 60 degrees, which will significantly limit the formation of scale.

After using an Ariston type water heater for several years, it becomes necessary to descale it. To do this, you need to disassemble this unit. The boiler heater, temperature sensor or electrical circuits may also fail, which also leads to the need for repair work at home.

How to disassemble a water heater with your own hands? How to repair and install Ariston yourself?

Figure 1. Ariston boiler diagram. To answer these questions, let’s briefly consider the design of the Ariston boiler.

The main elements of such a water heater are shown in the figure. Figure 1The main components of the boiler and the reasons for their failure:

internal tank (its wall thickness is up to 2 mm) - mainly fails due to corrosion. If you come across a high-quality Ariston, and you carry out preventive replacement of the magnesium electrode on time, then the tank will last for many years. Also, one of its malfunctions is poor water heating due to accumulated scale;
thermal insulation - there are usually no problems with it;
the tubes through which cold water enters and hot water exits do not, as a rule, need to be repaired;
the outer shell of the tank is metal or plastic, it fails only if the boiler falls;
thermoregulating device (sensor) - if it malfunctions, the water heater continues to operate, but it is impossible to determine to what temperature the water has been heated;
heater (heating element) - its failure is due to scale accumulated on its body and contacts, and then it must be replaced, which leads to disassembly of Ariston;
anti-corrosion magnesium electrode - its installation is carried out next to the heating element. It protects the body of the water heater. If you replace it periodically, there are no problems with it;
thermostat - serves to ensure automatic heating of water and is available in three types:

Rod.
Electronic.
Capillary.

The sensor reacts to an increase in water temperature and turns on or off the relay connecting the heating element to the electrical circuit.

Figure 2. Electrical diagram of the water heater.

Another part of Ariston (not shown in the figure) is an insulating gasket that provides sealing and electrical protection. Its location is at the junction of the flange (the heating element and magnesium anode are mounted on it) with the body of the water heater tank. It must be changed periodically, otherwise it may dry out and the boiler will leak.

Another component of the device is, for some models, an electronic control and monitoring circuit, without which the water heater will not work. In its usual design, the boiler has approximately the following electrical circuit. Figure 2. The following components are indicated by numbers:

1, 2 — thermostats for regulation and control; 3 — power indicator (light bulb);

4 - heating element; 5 - ground wire;

6 - electronic board.

The water temperature does not correspond to the specified parameters

Significant deviation of water temperature from the specified parameters

The problem arises in two cases, when the water from the heater is either too hot (literally boiling water) at minimum heating values, or cold and heating does not occur at all. There is also an intermediate malfunction, when the maximum heater values are set, and the water is slightly warm. All problems deserve attention, the causes of which can be quite numerous.

So, let's consider a situation where the water heater, at maximum values on the relay, produces only warm water in the tap, which is preceded by the following possible problems:

The heating element is covered with scale, it consumes more energy on heating, while the efficiency is at a minimum.
There are problems in the central board that are blocking the relay signal to the desired temperature.

If the water heater visually turns on and supposedly works, but in fact only produces cold water, then the reasons may be similar to those stated above. When the temperature of the water is exceeded, the problem lies in a malfunction of the thermostat or thermostat, which is responsible for fixing the heating parameters set by a person and maintaining this temperature inside the water heater.

If the problem is related to temperature mismatch, you need to perform the following sequence of actions:

Check the heating element for contamination and proper operation: disconnect the boiler from the mains, allow the water to cool and drain it as much as possible, then remove the protective cover at the bottom, open the valve and carefully remove the heating element. Using a multimeter, check the functionality of the element, which is fixed in the range of values 0.68-0.37 Ohm. If there is a break, the indicators will be unstable and will tend to infinity. If there is scale, it can be removed by soaking it in a special acid solution, which can be bought at any household store. Apple cider vinegar is an alternative.
Take out the thermostat and evaluate its performance: disconnect the boiler from the network, drain the water, remove it from the wall. Find the thermostat (you can see in the instructions what it looks like and where it is located for a specific model) and press the safety button all the way. Next, the metal tube needs to be slightly heated with a lighter. If the thermostat is working, then when it heats up it will react and return the button to its original position. If this does not happen, then you should completely dismantle and replace the element with a new one.

Similarly, you should go through all available contacts with a multimeter, since there is a possibility of a break, which provokes a lack of proper operation.

Expert opinion Vadim Savelievich Grebnev Heating systems installer

Before draining the water, you need to let it cool. If you don’t have time to wait, then the following trick will do: open the hot water tap to maximum, unplug the boiler. After about 5-7 minutes, the water in the tank will become slightly warm, which will facilitate the process of draining it.

Answers from experts

Fursov Yuri:

It’s quite possible that the tena’s shell is broken

Zaretskii Kostya:

A leak. Check the integrity of the heating element - drain the water, unscrew it and visually inspect it. If there are obvious cracks, replacement will solve everything. If the heating element is intact and in good working order, and the magnesium cathode is also still in good condition, then this is more complicated. If you have electrical measuring instruments, you can see the presence of leakage current if you know how to use them. No - consult with knowledgeable people.

BASIL:

How much is this a lot? the water heater has an indication when the heating element is turned on and heating, if you drain the water every half hour, it will continue to heat until the temperature you set is reached, the boiler alone cannot take more than 1.5 kW, and the meter runs well, no matter how much according to you, it’s a lot, 500-1000-2000 kW, you didn’t write, but if it works constantly, I think it alone will burn at least 150-200 kW, plus other appliances in the house at least 100-150 kW

Alexei:

So you heat 65 liters of water with a power of 2500W all day long, which you do not consume, it heats up, cools down and heats up again. And you use 15 liters from a can. 50 liters work on heat loss, the efficiency is 20-25%.

It is logical for you to buy a heater of the same volume as how much hot water you consume during periods of intensive water withdrawal.

For example, 30 liters or even 10. For example, with a programmable “memory function for daily consumption by time of day.” The heater will prepare water for you in the morning, at lunch and for dinner. the rest of the time it is disabled.

Small load with sinks. Leave the large 65 for the shower and turn it on separately.

You can buy a small one from Ariston, 20 liters with two cans of 10 and two alternately switched on tena 2500 for each can. Boiling water in half an hour.

Programmable with memory now from 8 and above.

Well, of course, the calculation is only correct if the equipment is in good working order. RCD performance.

Mr.Androws:

Water heater: .vensys /catalog/detail.php?ID=2535 off - enabled.

Nikolai Kros:

So what's the problem? Plug it in and that's it. Judging by the button and regulator, everything is turned on. on- will turn on; off-turns off. Why is the water shut off? Does it even have water at all? If you turned it on without water, the heating element could burn out.

Free wind:

What's so complicated? We supply cold water to the valve with the valve, from the other valve it goes to the apartment system of the mountains. water, while the inlet valve should naturally be closed (you’re not going to supply hot water to the whole house?)….))))))))))))))))))

The lineup

The Ariston brand produces many models of water heaters. Positive customer reviews clearly prove that this brand is number one in the market for the production of gas appliances. The Ariston Fast Evo model is the most popular of the entire line of heaters. The model is available in two types, differing in productivity (11 and 14 liters per minute). This is a turbocharged automatic car with electric ignition. To operate the device you only need two batteries. In addition, the model has a built-in flame modulation system. Such a system allows you to maintain temperature constancy.

The main advantages of Ariston Fast Evo include:

ability to work at two water intake points;
ignition occurs at minimum pressure;
optimal outlet temperature.

Another popular model is part of the Marco Polo series - Gi7S with a closed combustion chamber. The device is equipped with a flow-through heater and does not have a chimney. An important feature of the device is that the pipe is led outside, therefore, combustion products do not remain indoors, but go outside. Gi7S is the most powerful unit, therefore it is very energy-consuming. Among the more budget models, Ariston CA 11P is in particular demand. The unit has a classic design and is easy to operate. It stably maintains the set parameters and does not upset the settings.

Distinctive abilities

According to reviews of Ariston gas wall-mounted double-circuit boilers, they have 4 distinctive features that are useful for their owners:

All models of this company are equipped with automatic protection systems.
The presence of a water pump, which is necessary for constant circulation of water through the pipes.
Possibility to choose a model with an expansion tank. With its help, pressure will be automatically adjusted inside the heating system.
Ariston equips its equipment with various types of ignition. It can be automatic, which will make life much easier for the owner of a particular boiler. Otherwise, every time the unit starts, the person will need to press a special button.

Quality and weaknesses

Ariston water heaters have a stylish modern design, excellent functionality, and differ from analogues from other manufacturers at a reasonable price

Removing scale

After you empty the tank, you will need to disassemble the boiler yourself. To do this, carefully disconnect all the fastons connected to the thermostat and unscrew the bolts, of which there are usually 6 pieces.

When removing the heating element, some more water that remains in the tank will pour out. It is recommended to clean the heating element itself immediately, while it is wet and scale deposits have not hardened. For cleaning, we recommend using special products that can be sprayed onto the heater. After some time, the deposits can be easily removed with a wooden spatula or even a dull knife. Also, for repairs, you can boil the heating element in a bucket with the addition of a special acid to the water, which will effectively solve the problem. To be sure to get rid of scale, we recommend using fine-grained sandpaper (“sandpaper”) to clean the tubes to a metallic color.

After this, you need to reassemble the boiler in the reverse order and check whether the weak water heating was repaired. Do not forget that first of all you must fill the tank completely with water, after which you will connect the plug to the power supply and start.

We draw your attention to the fact that there is a situation when the boiler does not heat the water because the heater is broken. In this case, self-repair consists in the fact that you need to test it with a multimeter, setting the resistance measurement mode

We will tell you about this below!

Removing air pockets in the system

It's better to start with batteries. To remove air pockets, a Mayevsky tap is usually installed on them. We open it and wait for the water to run. Did you run? Let's close. Such manipulations must be done with each heating device separately.

After the air is removed from the batteries, the pressure in the system will decrease and the pressure gauge needle will drop. At this stage of work, the solution to the question of how to start the boiler involves re-filling the system with liquid.

Now, the most difficult thing is that starting gas boilers requires bleeding air from the circulation pump. To do this, the boiler needs to be disassembled a little. We remove the front cover and look for a cylindrical object with a shiny lid in the middle, which has a slot for a screwdriver. After we have found it, we put the boiler into operation - we supply it with electrical power and set the water heating controls to the operating position.

The circulation pump will immediately turn on - you will hear a faint hum and loud gurgling and many incomprehensible sounds. This is fine. As long as the pump is aired, it will be so. Take a screwdriver and slowly unscrew the cap in the middle of the pump - as soon as water starts seeping out from under it, screw it back. After two or three such manipulations, the air will come out completely, the strange sounds will subside, the electric ignition will work and start working. Check the pressure again and add water to the system if necessary.

Basically, that's it. While the system is warming up, you can begin to study the instructions in detail (if, of course, you have not already done so) and start debugging the system that involves starting the boiler. Everything is simple here - the batteries closest to the boiler need to be screwed on, and the ones farther away need to be turned on to their full potential. This debugging is carried out using control valves installed on the supply connection pipe to the heating radiator.

How to remove and check the heater

Most often, heating elements in storage boilers break because they are constantly in the water. Regardless of the volume (50, 80 liters or more), the service life of the part can be influenced by various factors:

Frequency of boiler use.
Maximum heating temperature.
Water quality.

Why do parts burn out? This happens when you turn on the equipment without water. Although most manufacturers prevent this point with the design features of the tank. Therefore, the main reasons for the heater to burn out will be water with a large amount of impurities and scale. The sediment covers the element in several layers, interfering with normal heat dissipation. As a result, the heating element overheats.

How to remove the heater with your own hands? First of all, unplug the boiler.

Regardless of the brand (Polaris, Elenberg or Termex), turn off the machine in the control panel. Now start draining the water.

Draining the boiler

There are several ways to delete content. Via check valve:

Place a deep container under the valve or connect a hose and lower it into the chamber.
Open the valve and let the water drain out.
With a tank volume of 30 liters, the procedure will last at least 1 hour.

What tasks do heating elements perform?

Water heaters with “dry” and “wet” heating elements
The heating element for an Ariston water heater can be “dry” or “wet” and they differ from each other in the principle of their location. “Dry” products are in demand because they are placed in a protective casing, which prevents contact with water.

Such heating elements have their own characteristics:

longer service life;
longer water heating;
higher cost.

Since “dry” heating elements are at the development stage, there are several variations of them.

The simplest and most common option is when the heating element is placed in a flask. Such a product has a minimal cost and does not cause difficulties when replacing.
There is a mechanism whose flask is filled with quartz sand. This option is easier to replace.
There are also products where the bulb and heating element have a layer of oil between them. Since oil has greater thermal conductivity than air, this product achieves maximum energy savings.

There is also a heating element for Ariston “wet” type.

The open element is in contact with the liquid in the storage tank. Inside the heating mechanism tubes there is quartz sand or magnesium oxide. These substances conduct heat efficiently.

Open-type heating elements are classified according to the following technical characteristics:

Is there an anode socket? A heating element with a nut may not be equipped with an anode fastening or may have it as an additional one - a clamp on the flange.
What method of fastening? The element can be fastened with flanges or nuts. Flange heaters are manufactured using casting or stamping technology.
The shape of the heating element depends on the type of storage tank. Can be straight or curved in any direction.

Stainless steel and copper are usually used to make a “wet” device.

Design and principle of operation of the Ariston water heater

The modern Ariston boiler for 30, 50, 80 and 100 liters is a sealed structure consisting of the following parts and assemblies:

Storage tank:
Electric heating element (TEH);
Magnesium or zinc sacrificial electrode;
Setting and control unit;
Casing.

The inner surface of the tank must undergo anti-corrosion treatment. Depending on the cost of the product, various modifications may have the following as anti-corrosion protection:

Titanium coating;
Glass porcelain coating;
A layer of heat-resistant enamel that is resistant to aggressive compounds.

In addition, expensive premium water heater models may have all-metal welded storage tanks made of alloy stainless steel.

The air gap between the casing and the inner container is filled with a polymer heat-insulating composition (most often, polyurethane foam). Thermal insulation allows you to significantly slow down the cooling process, thereby reducing energy consumption.

Heating elements are divided into two main types: “wet” and “dry”. Heating elements that come into direct contact with the heated liquid are called wet. In the process of interaction with the working environment, a persistent coating of insoluble scale forms on the outer surface of the heating element, preventing normal heat transfer. To protect against corrosive destruction of the heating elements and the inner surface of the tank, a zinc or magnesium anode is used.

The functionality, information content and ergonomics of a water heater largely depend on the design and design of the control unit and settings. There are two types of control mechanisms: electronic and mechanical. Digital systems have an attractive appearance and are distinguished by precise settings, but are extremely sensitive to voltage fluctuations.

The mechanical unit looks “simpler”, and the adjustment accuracy is not the same, but the reliability of such devices fully compensates for these shortcomings. In addition, the price of models with electronic adjustment is noticeably higher.

The casing of the unit can be made of both metal and polymer materials. The most common is the cylindrical shape, but models of other configurations are in demand.

Design

Fundamentally, the design of any water heater (boiler) resembles the design of an electric kettle with the function of maintaining a given temperature. But instead of a lid, this kettle has a safety valve.

Depending on the brand, its copyright holder includes a variety of marketing and technical options in the design. Such options are designed to distinguish the product of this particular brand from another.

The hallmark of Ariston storage water heaters is, among other things, the corrosion-resistant coating of the internal tank containing Ar+ silver ions.

This does not exclude the use of other protective coatings in other products of the company. The Ariston AM50 SH 2.0 Ei3 FE model (horizontal model) uses Ti-enamel as a protective coating.

Structurally, such a device consists of:

external, heat-insulated housing (tank);
internal tank with a volume of 15 liters to 200 liters with a corrosion-resistant coating or made of stainless steel;
Heating element – heating element: in a tank with a wet heating element – direct contact with water;
with a dry heating element – contact with water through a ceramic shell;

magnesium anode - to protect equipment from electrochemical corrosion. Does not affect scale formation;

thermostat - to receive a signal about the actual water temperature;

electronic unit - for setting and regulating the water temperature inside the tank;

gasket for the heating element fastening unit.

Take note: the magnesium anode should be replaced at least 1-2 times a year.
