Ariston water heater with a volume of 50 liters, a storage boiler with a displacement of 50 liters - operating instructions, do-it-yourself repairs

Read an article on how to disassemble and clean a Thermex water heater here.

Using a valve included in the device, a cold water pipe is connected. If they are not very oxidized, you can clean them with a small piece of cloth soaked in alcohol, place the cloth on the bottom plate and rub. Remove the flanges and gain access to the inside of the water heater. █ THERMOSTAT. Water heater and HIDDEN emergency shutdown BUTTON

The operating instructions contain all the necessary information regarding installation, connection, conditions of use and frequency of maintenance of the Ariston storage water heater. But to repair the tank, you will have to cut off the top, or remove the thermal insulation and cook it from the outside.

But if you repaired the heater yourself before the warranty expired, then you should not count on the warranty.

It is tested for contact activation at room temperature and at C. In this case, all joints between fittings and pipeline fittings must be dismountable threaded.

The models are easy to install and maintain.

Do-it-yourself boiler repair Ariston

To independently repair Ariston storage water heaters (volume 50, 80 or 100 liters) at home, you need to familiarize yourself with the main design components:

Temperature sensor. If it breaks down, the boiler will not stop working, but it will not be possible to determine the temperature of the water and its quantity;
Thermal insulating casing - due to it, the temperature of the water in the Ariston water heater is maintained;
The outlet pipe for hot water to flow outside, as well as the heat-insulating element, does not require repair;
Water supply tube;
Metal or plastic outer shell of the Ariston water heater;
The inner container is made of stainless steel, with a wall thickness of up to 2 mm. May require replacement if it is damaged by electrocorrosion caused by anodic current;
Magnesium anode – resists the effects of anode current and protects the internal container from corrosion;
Ten is a water heating element. The speed of heating water depends on its power. This element, more often than other parts of the Ariston boiler for 50, 80 liters, requires DIY repairs;
Thermostat – performs the function of automatically starting water heating;
Insulating seals require scheduled replacement. They perform the function of sealing the joints of the Ariston water heater structure and provide electrical protection.

The design of Ariston instantaneous electric water heaters is similar to the storage type, but it does not have a storage tank of 50, 80 liters, and the heating element has a higher power.

Problem with the electronic board in the Ariston model

If the electronic board of the water heater fails, you will need basic knowledge in the field of electrical engineering.

Since the board is put into operation in parallel with the electrical power circuit of the heating element, it can be turned off and the circuit can be connected as on conventional boilers, after which the equipment will work.

Malfunction and repair of the heating element

When the Ariston boiler is turned on, the heating element operation indicator does not light up, the water does not heat up:

Using a tester, we determine the malfunction. Having set the scale on the measuring device to 220-250V, we measure the connection of the thermostat and the cable at the terminals; at normal voltage, we proceed to measuring the voltage of the heating element. If in this case the voltage is normal, it means that the heating element itself has broken;
Turn off the boiler and set the tester to a resistance measuring scale. We disconnect the heating device from the thermostat, the ends of the heating element are exposed. We carry out measurements on the contacts; if the device is working properly, the tester will show a certain level of resistance (accuracy is not important here). If there are no indicators, the heating element of the water heater cannot be repaired.

A thematic video will complement the above.

Thermoelectric models

(for models with a capacity from 50 to 300 liters inclusive)

An additional operation for this type of water heaters is to connect them to the central heating network.

Connect the top terminal of the water heater to the rising circuit of the central heating system, and the lower terminal to the descending circuit, using 2 valves.

We recommend using the bottom valve to disconnect the device from the central heating system when the heating system is not working (valves for connecting to the central heating network are not included in the delivery package.)

Cleaning and Maintenance

Following the manufacturer's recommendations can save the boiler owner from many problems. For example, the instructions usually recommend regular maintenance of the boiler, which boils down to an external inspection and cleaning procedure.

Typically, recommended maintenance periods vary depending on the type of heating element and the nature of its operation. For “wet” heating elements, it is recommended to clean them annually, and for “dry” heating elements - at least once every two years.

If the device is used under increased loads, for example, in production or in a public place, then maintenance should be carried out every six months, regardless of the type of heating element.

During operation, scale and debris accumulate inside the boiler; to remove these contaminants, the device should be cleaned regularly

The maintenance procedure may affect warranty service. Sometimes the manufacturer indicates in the documents that the procedure should be carried out not by the owner of the device, but by repairmen certified by the manufacturer. In this case, it is better to follow the manufacturer's instructions.

Carrying out maintenance yourself is not too difficult. To do this, you need to disconnect the boiler from the power supply and water supply, and then drain the water inside. After this, the housing is opened by unscrewing the fastening bolts and the heating element is removed. The heater and the inner surface of the tank are cleaned of scale and dirt.

The protective gasket and magnesium anode are replaced. Then the device is reassembled and connected to the electrical and water supply networks. One of the common causes of damage to the boiler tank is so-called electrical corrosion. It gradually destroys the surface of the drive, which leads to leakage.

To prevent this problem, many manufacturers install a magnesium anode next to the heating element. This element does not last forever; the task of the device owner is to promptly replace it with a new element. Unfortunately, some people forget about this, which can result in their boiler being completely damaged.

The magnesium anode gradually wears out, it is recommended to replace it with a new element every year or two, depending on the heating element model

Do not forget about such an important protective element as grounding. Its absence not only creates a risk of injury when operating the device, but can also intensify or provoke electrocorrosion

Blitz tips

A few tips that will allow you to extend the life of the device without overpaying for electricity:

Do not unplug the device. Maintaining a set temperature takes much less energy than heating it up. This is especially true in winter, when the water temperature is especially low.
If hot water is needed less often than once a day, then it is better to turn off the device. In this case, heating will take less energy than maintaining the temperature.
Significant savings are achieved through controllers. The unit can be programmed to heat water at the desired time.
If possible, use the controller mode marked “E” (Eco).
Do not allow water to flow aimlessly. Once again, turning off the tap for a couple of minutes will save you a lot of energy and money.

Characteristics and types

The flexible hose for connecting plumbing is a hose of different lengths made of non-toxic synthetic rubber. Thanks to the elasticity and softness of the material, it easily takes the desired position and allows installation in hard-to-reach places. To protect the flexible hose, there is an upper reinforcing layer in the form of a braid, which is made from the following materials:

Aluminum. Such models can withstand no more than +80 °C and retain functionality for 3 years. At high humidity, aluminum braiding is prone to rust.
Of stainless steel. Thanks to this reinforcing layer, the service life of the flexible water line is at least 10 years, and the maximum temperature of the transported medium is +95 °C.
Nylon. This braid is used for the manufacture of reinforced models that can withstand temperatures up to +110 °C and are designed for intensive use for 15 years.

The fasteners used are nut-nut and nut-fitting pairs, which are made of brass or stainless steel. Devices with different permissible temperatures differ in the color of the braid. Blue ones are used to connect to a pipeline with cold water, and red ones for hot water.

When choosing a water line, you need to pay attention to its elasticity, reliability of fasteners and purpose. It is also mandatory to have a certificate that prevents the rubber from releasing toxic components during operation.

If the drain filter leaks after cleaning

After the part is cleaned, you will need to check the washing machine for leaks. It should be borne in mind that it may not appear immediately, but only after several washes.

There are a number of reasons why a washing machine leaks.

The first and main reason is incorrect installation of the drain filter. It could be screwed in loosely or crookedly. The part must be screwed in without distortion to prevent accidental shifts along the thread. In this case, the element must be tightened tightly, but very carefully. It is worth remembering that with strong pressure when tightening the lid, you can damage the threads on the plastic part. To eliminate a leak, just unscrew and reinstall the unit in its original place, correcting the misalignment and fixing it tightly. Secondly, the integrity of the rubber gasket, which ensures the tight installation of the drain filter, could be compromised

It could crack during use or become damaged due to careless removal of the part, as well as during careless cleaning using cutting tools. To eliminate such a breakdown, you will need to replace the rubber seals, if they are commercially available, or install a new drain filter. The third reason for filter leakage is its damage or thread defect.

This could happen if the part was removed incorrectly or if the cap was tightened too much. As a result, the contact of the drain elements becomes weaker, which is why a leak appears. To fix the breakdown, you will need to replace one or several parts at once, for example, a filter and a snail. If you are not sure that you will be able to perform all the steps correctly, you should seek help from professionals.

The water heater is broken: the main causes of the malfunction

Despite the reliability and quality of Ariston heaters, they tend to break down. The weakest points of the water heater are: the heating element, a special magnesium anode, and a check valve. It is these elements that need timely prevention.

What to do if your water heater breaks down? First, you need to identify the causes of the breakdown, and only then move on to eliminating the malfunction itself.

Reasons for failure of water heating tanks:

Corrosion (scale) has formed on the heating element;
The filter on the pipe through which water is supplied and on the check valve is clogged;
Power surges in the network lead to the control board failing.

When starting self-repair, be sure to check the device’s warranty card. If the warranty on the tank has not expired, do not rush to disassemble it, otherwise you will not receive free service in the future.

Cold or insufficiently hot water flows from the boiler

The cause of a malfunction of this nature may be a breakdown of the heating element, thermostat and a large layer of scale on these devices. Before determining the cause of the malfunction of the Ariston 80-liter water heater and doing the repair yourself, you should turn off the power supply and drain the water.

Then, using a 13 mm wrench and a Phillips screwdriver, remove the protective box and unscrew the bolts on the mounting plate. Carefully remove the flange on which the heating element and thermostat are attached. Now you need to descale these 2 devices.

Boiler protective cover

The thermostat should be unscrewed, cleaning the attachment points to the flange from sediment, then carefully, using a screwdriver, free the thermostat from scale. You can check the functionality using a tester; the absence of a signal on its contacts indicates a malfunction and the need for replacement, since the thermostat cannot be repaired.

You can also check the heating element for functionality using a tester by connecting the ends of the tester to the contacts of the heating element. If there is voltage, the heating element is working, but it needs to be cleaned. The heating element can be cleaned using a screwdriver, carefully removing pieces of deposits.

Then you need to prepare a solution of citric acid - 100 g per 1 liter of water and immerse the heating element in the solution. The effect of the solution on the device will be indicated by air bubbles that appear as a result of the reaction. If this action is not enough for complete cleansing, you can put the vessel with the solution and heating element on low heat.

After cleaning the heating element, you need to descale the tank. Be careful not to damage the inner surface of the tank. If it is possible to remove the heater from the wall, cleaning can be done using a solution of citric acid, pouring it into the tank.

There may be a lot of debris in the tank

After these manipulations, assemble all the parts in the order in which they were disassembled and carefully insert and secure the flange. Make sure that during assembly there are no distortions of parts, do not overtighten the bolts, change the gasket between the body of your storage boiler and the flange, since the flange gasket was also exposed to salts.

Typical water heater connection errors

Safety valve. The most common mistake installers make is failing to install the valve. Replacing the safety valve with a non-return valve (which allows liquid to flow only in one direction) is also incorrect - this can lead to increased pressure on the device. As a result, leaks, tank depressurization, and the need to replace gaskets. A working safety valve periodically drips and leaks (especially when the water is very hot when no one is using it). You should be wary of the fact that the valve always remains dry! There is a possibility that it clogged and failed.

Tank orientation. The second common mistake is installing a horizontal device vertically, and vice versa. Do not rush to purchase a heater until you decide exactly where and how it will hang. Which location is more convenient? If the family moves often, or cannot decide on a location, it is better to immediately purchase a universal boiler.

Electrics. It is best not to use an outlet that is located in a damp place or where it may be splashed. A prerequisite is a grounding contact. It is desirable to have a separate line with its own machine and through an RCD. Choosing the wrong machine is also a common mistake. It must be bipolar with a value of 16 A if the boiler has a power of up to 3 kW. Three-core copper cable with a cross-section of 2.5 mm2.

Fastening. You cannot hang a heavy tank (100 liters or more) on a wall or sheathing; they may not be able to support the load. The hole for the dowel should go into the wall to a sufficient depth. Small boilers up to 50 liters can be hung on a plastic dowel. If the volume of the container is larger, it is better not to risk it and use steel anchor bolts.

Water supply. Of course, installing a flexible plastic pipe is much easier. But if the boiler is planned to be located at a considerable distance from the cold riser (more than 1.5 m), then preference should be given to metal. Rubber hoses should not be used; they wear out too quickly.

Water with impurities. Hard and dirty water is the main reason for failure of heating elements. The mistake in this case would be to do nothing. If the problem occurs, it is worth installing a fine filter at the inlet

It is also important to periodically change the magnesium anode.

Even if this is not the first time you have to install a boiler, read the installation instructions and remind yourself of the basic requirements and principles of connection!

Device selection

How to choose the most suitable device for your apartment? Let's say you have decided on the volume, deciding that 80 liters is enough for you. You need to decide what price you are willing to pay for this pleasure. Budget boilers are no worse than expensive ones. Maybe not as beautiful with less precise settings, but Ariston provides a guarantee for all its models.

Next we decide on the form. It all depends on where you are going to hang it. You can take round or flat. Perhaps, if there is absolutely no free space on the walls, a horizontal water heater will be the only option.

If you want to save money, take a 1.5 or 1.2 kW device. It will heat up more slowly, but you will save on electricity. Naturally, it is necessary to do what we do with any product in the store - check its integrity with the package. Don’t listen to sellers’ excuses like “it’s a small dent, it’s no big deal,” you’ll have a long time to live with this device, ask for a replacement.

Budget boilers are no worse than expensive ones. Maybe not as beautiful with less precise settings, but Ariston gives a guarantee for all its models

How to turn it on

The design of all boilers (storage water heaters) is the same, so it depends little on the model and brand. Considering that, according to statistics, the most popular manufacturers among Russian consumers are Thermex and Ariston, using their example, we will tell you separately how to turn on the Thermex boiler and how to turn on the Ariston water heater.

The initial installation of equipment is mainly done by specialists, but switching on must be done by the users themselves.

So, how to turn on a Thermex water heater so as not to damage it and prevent mistakes. Connecting an instantaneous water heater is not fundamentally different - the air is also vented, the hot water pipe is shut off, the settings are set and it starts up. The only difference is that the storage one takes 2.5-3 hours to heat the water, and the flow-through one dispenses it after 5-15 seconds.

The shut-off valve on the hot water pipe is closed.

Even if a tap is installed on the pipe, shut-off valves are still used. The taps can let water through, and then the water from the boiler will go into the common riser.

Air is released from the system by opening the hot water tap and the outlet of hot water from the boiler itself; lastly, open the cold water tap. The presence of air can be determined by a ragged stream - it will flow intermittently and a “snorting” sound will be heard.
After the water flow has leveled off, close all the taps, including those on the device itself. Next, connect it to the network.

A separate grounded socket is always used for connection.

Before turning on the boiler, set the temperature and check the operation.

To make sure it works, do the following:

check the indicators;
check the temperature;
If the device is working properly, the temperature will rise after 15-20 minutes.

If the water heater does not turn on

The first thing you do is check the network elements - electricity, sockets, RCDs, automatic devices. Use a tester to check the voltage in the boiler to rule out a broken cable.

The most common problem is electronics. If power is supplied, but the Thermex water heater does not turn on, look at the error code on the display and check the instructions to see what it means.

breakdown of the heating element, contamination of the heating element with lime and calcium deposits;
thermostat failure - when the water temperature rises above 90-92 degrees, the RCD may be triggered;
there is no water in the tank - if there is water in the system, but it does not flow into the boiler, the reason may be that the air has not been bled.

Even if there was water in the tank before turning it on, but it has not been used for a long time, you should first drain the water, and then be sure to drain the air.

Let us repeat that there is no fundamental difference in connecting storage devices, so we will schematically describe how to turn on an Ariston boiler.

If we are talking about an apartment or house with a centralized supply of hot water, close the pipe with shut-off valves.
Open the tap in the place where the unit is installed and drain the water, close it.
You bleed the air from the boiler, for which you first open the inlet tap (the pipe is marked in blue), then the heated water tap (marked in red). Wait until all the air comes out and the water flows in an even stream without interruption.
Do not close the cold water supply tap - its quantity in the boiler is regulated automatically.
Plug it in and set the temperature on the device.
Check the functionality - after a few minutes the temperature in the tank should begin to increase.

What errors can you encounter during operation?

Instantaneous water heaters

As for compact water heating devices, we note that their installation is very simple:

remove the old tap;
install the unit;
connect to a pipe with cold water;
turn off the hot one;
plug into the outlet.

At this point, the installation is complete and then you just need to turn on the hot water tap and use it. With this equipment, there should be no questions about how to turn on the boiler when it is already installed. If you don’t risk installing it yourself, contact a specialist.

All listed devices belong to high power equipment (from 3 to 7 kW), they are prohibited from being connected to a common outlet. A separate outlet should only be located in a dry place, and power should be supplied directly from the distribution panel.

General information

The Ariston boiler is used to heat water in a system with a single-circuit boiler.
Ariston heaters are devices of stylish modern design, functional, safe, and at the same time affordable. The company produces household water heaters for periodic use, when hot water in the apartment is turned off. Such boilers are quite compact, but allow you to store enough hot water for daily needs: washing dishes, hygiene procedures, cleaning. Larger boilers of 100-150 liters or more are designed for servicing country houses and are used year-round, used as the main source of hot water.

What you need to know about Ariston boilers

The main function of Ariston water heaters is to provide houses, apartments, cottages, and cottages with hot water supply for household purposes. In order for the electric water heater to serve for a long time and with high quality, the following characteristics were observed:

the internal tank is made of high-quality anti-corrosion material - stainless steel, the internal walls of the water heating tank are coated with a special coating to prevent plaque formation;
High efficiency heating element with reliable insulation;
internal dividers that do not mix cold water with heated water;
intelligent control system;
overheating protection using control sensors;
high-quality thermal insulation allows you to maintain the water temperature for a long time;
the presence of a professional antibacterial coating;
ease of use.

It should be noted that the instructions for water heater models that differ only in the system of different volumes of the same series are almost identical. There are two types of heaters based on the principle of operation: flow-through (the heat exchanger heats the temperature instantly as soon as you open the tap) and storage (water is drawn into the tank and then heated). Storage water heaters, or boilers, have a compact tank designed for different volumes - 30, 50, 80, 100 liters. Boilers can be directly heated (they heat the water themselves using gas or electricity) and indirect (such devices are located near a heat exchanger, for example, a boiler).

Installation of the device must be carried out by a specialist, otherwise your equipment will lose the right to warranty service. After installing an electric water heater, check the following:

Are there any water leaks: to do this, disconnect the water heater from the network and turn on the cold water filling;
At the same time, we also turn on the hot water tap to see when the boiler is completely filled. As soon as warm water flows from the tap, the boiler is completely filled with water. Close the tap and check the boiler itself to see if there is any dripping from the connections.
Only after you are sure that there is no leakage, insert the water heater plug into the network and select the desired heating mode.

About installing an Ariston electric water heater according to instructions

Before installing the water heater, make sure the wiring can handle the added power.

It is especially important that the outlet you are going to connect the device to is grounded and not exposed to water. Power to the water heater must come from the panel via a separate cable

When choosing a place to install an electric water heater, take into account its triple weight with water and the strength of the walls.

For fastening, hooks of at least 15 mm in size are required. It is recommended to install the water heater in close proximity to the dispenser, which will also reduce heat loss when supplying water to the point of disassembly. The distance from the ceiling is at least 10 cm, the space around the device is within a radius of at least 50 cm for technical work.

Under what conditions should the device not be installed?

prevent splashes of water

If the water pressure is low, it is necessary to set the maximum temperature mode, otherwise the device may not turn on at all.

Brand name parts only

All parts of the water heater must be in good working order when first installed. This is especially true for the safety valve. If damage is noticeable, the part should be replaced with a similar one. Do not use adapters or extension cords under any circumstances, or replace the water heater plug with another one. A separate power line to power the boiler is required. If the power cord is damaged, replace it with a similar one.

When disconnecting the electric heater, use a two-pole switch, the gap between open contacts is from 3 mm

Also note that the pipes to which the water heater connections will be connected have withstood temperatures exceeding 80 degrees Celsius and the maximum operating pressure

Precautionary measures

If you know you won't be using the appliance for a while, simply drain all the water from it. To do this, turn off the power to the device, close the cold water supply valve at the water heater, and open the hot water tap on the mixer. Open the drain valve of the tee. The magnesium anode, which will be used up over time, should be replaced with a similar one. The first start-up of the device should be carried out strictly according to the instructions.

Price

The Ariston model range is very diverse. We also see a wide range in terms of the cost of devices. From economy class models to very comfortable ones. Let's look at several samples from the 80 liter line, but at different prices.

Let's start with the most modest:

Ariston SUPERLUX NTS 80V price 5,650 rubles. Tubular heating element, maximum temperature 75 degrees, power 1.5 kW number of heating elements - 1. Mechanical control, heating time 186 minutes. The inner coating is enamel. Maximum pressure up to 7 atmospheres.

Now let's look at a more expensive model:

Ariston ABS PRO ECO INOX PW 80V price 11,046 rubles. Temperature up to 80 degrees. Power 4 kW. Number of heating elements – 2. Electronic control (buttons). Internal covering – stainless steel. Protection against turning on without water and protection against overheating. Accelerated water heating.

As you can see, there is a difference. Let's look at an even more expensive model:

Ariston VELIS INOX 80 l price 22,990 rubles. The internal tank is made of stainless steel with special protection. Ultra-fast water heating. Protection against: electric shock, switching on without water, power surge, bacteria. Ultra-precise temperature control. Automatic error diagnosis. Improved magnesium anode. Electronic control. Polyurethane foam thermal insulation. Power 1.5 kW.

That's the difference. If any of the listed data is important to you, you can pay extra and buy yourself a more expensive device. If not, then a budget model will suit you just fine.

Features of gas connections

When connecting gas stoves, water heaters and other types of equipment, flexible hoses are also used. Unlike water models, they are yellow and are not tested for environmental safety. For fixation, end steel or aluminum reinforcement is used. There are the following types of devices for connecting gas appliances:

PVC hoses reinforced with polyester thread;
made of synthetic rubber with stainless steel braid;
bellows, made in the form of a corrugated stainless steel tube.

The Santekhkomplekt holding offers engineering equipment, fittings, plumbing fixtures and devices for connecting them to communications. The assortment is represented by products and materials from well-known foreign and domestic manufacturers. Discounts apply for bulk purchases, and product quality is confirmed by standard certificates. For information support and assistance, each client is assigned a personal manager. The ability to arrange delivery within Moscow and to other regions of the Russian Federation allows you to quickly receive the purchased goods without unnecessary hassle.

Drainage is a drainage and drainage measure to remove excess groundwater.

If water does not leave the site for a long time, the soil becomes gleyed, if shrubs and trees quickly disappear (get wet), you need to urgently take action and drain the site.

In what situations is it necessary to drain water?

There are only two such situations:

If Ariston is left in an unheated house for the winter. The fact is that the water inside the storage tank will simply freeze and burst it. But remember one important thing - the material that has been in the water all the time must remain in it. It's all about the negative effect of water on many materials, especially metal. Under the influence of oxygen, after the water has been drained, this material begins to quickly corrode, so rust in an empty Ariston is common.
If your water heater needs to be repaired. There are no options here - as long as there is water in the tank, it is impossible to repair Ariston.

What to do

Ariston water heater design. (Click to enlarge)

To begin self-repair, you should pay attention to the features of its design and operating principle. Typically the tank includes the following functional units:

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.

You can do this yourself at home, following a certain sequence:

Disconnect the boiler from the power supply if the heating element does not heat.
Turn off the cold water supply and drain the water heater.
Remove the protective cover and disconnect the wires (you must first draw a connection diagram or photograph it, which will facilitate the reassembly process).
Unscrew the flange nuts using a wrench.
Place a container under the tank and carefully remove the flange with the heating element and the magnesium anode (its remains).
Clean and wash the internal walls from scale and dirt.
Install a new heating element and magnesium anode.
Reassemble all parts in reverse order.
Before connecting to the power supply, draw water and check the tightness of the assembly for several hours; the tank should not leak (otherwise, do not turn on the tank; you will need to install a new gasket on the flange).

Read an article on how to disassemble and clean a Thermex water heater here.

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.

Watch the video in which an experienced user explains in detail how to repair an Ariston water heater with your own hands:

Operating principle of the heating element

The heating element of the boiler is a curved tube, through the center of which runs a conductive thread with high electrical resistance. When current passes, it releases a large amount of heat, which is transferred to the contents of the tank.

To avoid short-circuiting the thread in water, it is enclosed in a heat-conducting insulating layer - quartz sand or magnesium oxide. From the outside, the system is immersed in a copper or stainless steel tube.

When the thermostat receives a signal that the water temperature is too low, it closes the circuit, turning on the heating element. The tube operates until the liquid at the level of the thermal sensor sleeve is heated to the desired level.

If water comes into contact with the outer metal shell, then such an element is called open or “wet”. The heating element, in which the tube is enclosed in a sealed ceramic flask, is closed or “dry”. The first has an advantage in heating speed, and the second in service life.

Diagram of a heating element in a water heater.

When to change the anode

The service life of the element depends on 2 factors - operating mode and water hardness. There is no need to explain the intensity of the boiler’s operation - the higher the flow rate in the DHW system of a private home, the higher the load on the heater parts.

Water hardness is determined by the content of calcium and magnesium salts. The higher their concentration, the faster the electrochemical corrosion reaction occurs and the faster the anode metal decomposes. In soft water the process slows down greatly, in distilled water it is reduced to zero.

How often does it need to change the magnesium anode depending on the operating conditions of the hot water storage tank:

With continuous operation + hard water – annually.
Regular tap water, the heater operates constantly - once every 2 years, at least.
At lower loads, it is worth cleaning the boiler once every 2 years and monitoring the condition of the element.
An exception to the rule is a titanium rod that works in conjunction with an external power source - the so-called active cathodic protection. The system is designed for a long service life.

Reviews

We have two children in our family who need to be bathed regularly. Therefore, it was necessary to urgently resolve the issue of purchasing a water heater. We chose an 80-liter Ariston machine via the Internet. So far we have never regretted it. The device consumes 1.5 kW per hour. Heats water up to 75 degrees. The temperature stays for quite a while.

I have a flat Ariston at home. I chose it for the toilet room. Fits perfectly. The lighting is so powerful that it illuminates the entire toilet. Now I save twice as much.

I am constantly at the dacha, so I decided to install the water heater there. I like the fast heating mode. I don’t save water; 80 liters is enough for almost all needs.

I don’t know about other boiler manufacturers, but I definitely like Ariston. I bought Ariston ABS Velis Inox 80 in the spring, now it’s winter and no complaints. We couldn't be happier. Consumes little electricity. I would like to draw your attention - take stainless steel devices. 7 year warranty! Enough for the whole family to wash themselves and there is some left over for laundry.

We needed a stylish, inexpensive compact model. Our choice fell on Ariston ABS VLS PW 80.

The model has an excellent design, glossy surface with silver details. Black control panel, blue backlit buttons. It is compact, flat, and fits perfectly into the bathroom.

Clear controls. The desired temperature can be easily adjusted. There is a fast heating mode. Over several years of operation, there were no complaints about the operation of the water heater.

How to connect an Ariston water heater

First, the water heater is mounted on a wall or supporting surface and the outlet (cold water) is provided from the water pipe. It is most beneficial to install the device as close as possible to the source of water supply - this allows you to minimize heat loss.

If there is a collector in the system, a separate cold water supply pipe is transferred to the installation site of the water heater. If there is no collector, the nearest section of the water pipe is cut, and a standard tee is installed at the cut site.

The method of installing the tee depends on the material from which the pipes are made. Plastic fasteners are fastened using a special soldering iron, and metal ones are fastened with threads.

A ball valve is installed in a separate section of the water supply system, designed to shut off the cold water supply.

To connect the water heater to the water supply:

Pay attention to the hot and cold water pipes - it is important not to confuse them. A check valve is installed for cold water; it can be included in the standard kit. Hot water is connected using a pipe

First, a cold water pipe is installed, then a hot one. A special tape is wound onto the threads as a sealant and sealant; this is recommended by the manufacturer. A tee is installed on the cold water pipe, at the bottom of which there is a relief valve. A tap is attached to the side to completely drain the water from the tank in case of an emergency, possibly due to abnormal pressure or heating. A shut-off valve and adapter are installed at a short distance under the tee. The next step is connecting to the water supply. Connection to hot water is also made by installing a shut-off valve. When connecting different metals, adapters should be used.

Connection to the electrical network is carried out as follows:

A separate circuit breaker (RCD) is installed in the distribution panel; it is connected to the central automatic fuse. A three-core cable is pulled from a separate RCD to the boiler, which is placed in an external cable channel (or a special groove is punched into the wall).
It is recommended to install a 16 A fuse as a switch, since the socket and plug are subject to heat and moisture. In addition, the cost of waterproof electrical equipment is higher than the cost of a machine. The “switch” is closed in a compact cabinet with a removable panel.
A separate RCD and the “switch” are connected by wire.
A three-wire wire is connected to the heating element; for this, the bottom panel is removed from the water heater.
Then the output of the machine is connected to the boiler.
At the next stage, the ground, phase and zero lines are wired to the corresponding connectors.

Before turning on the device, you must make sure that there are no leaks and that the flange is in the correct position (strictly in the middle). Then fill the tank with cold water and open the hot water tap to release the air. After bleeding the air, the valve is closed and a test operation is performed.

More detailed advice and instructions for operation and installation can be obtained from the KVANTA+ company in Tyumen.

Under what conditions should the device not be installed?

Electrical appliances, in particular an electric water heater, must be installed in conditions that correspond to those specified in the instruction manual.

The following are stated in the instructions for Ariston boilers as unacceptable factors for installation:

frost - this is associated with the risk of freezing water in the tank and pipes;
sunlight - do not expose the electric heater to direct sunlight;
power outages - the voltage in the network to which the device is connected must be stable;
vapors, dust or gas - the water heater must not be installed in a room with a high concentration of dust and toxic or acidic gases/vapors in the air;
dampness - it is not recommended to install the device in conditions of constant dampness and in long-term unventilated rooms (this item depends on the degree of moisture resistance of the selected water heater model).

Removing the Housing Cover

Inexpensive heaters without adjustment devices usually have two screws on the bottom cover of the housing. They need to be twisted with a Phillips screwdriver and the cover removed. If the cover is too tight, you can pry it off with flat-head screwdrivers.

A special place is occupied by models with oval flanges. They are dismantled directly on the wall; it is not advisable to turn them upside down with the fittings. Near the fittings (they are marked in blue and red) there are two bolts, unscrewing which you can remove the cover.

On some models it is not immediately possible to immediately find the screws to remove the cover. They are hidden under stickers. After removing the stickers, you can unscrew the housing cover. Sometimes, before removing the cover, you need to remove the plastic shields and plugs from the screws.
