Ariston 100 liters user manual. Ariston water heater (80 liters): model characteristics and their main advantages

18.10.2019

Ariston Company is the largest manufacturer of household appliances, which began its work in 1975. The president of this organization is the Italian Vittorio Merloni, who is also its founder. In 1980, Ariston became the European leader among manufacturers of household appliances and electronics.

Advantages of water heaters:

Safety. adapted to almost any working conditions. They are also equipped new system security to prevent emergencies.
Durability. The long service life of the heaters is ensured due to the high-quality materials from which they are made. This is mainly stainless steel with protective welds, as well as a steel tank with a titanium coating.
Ease of use. On the front panel of the boiler there is simple system control, with which the desired heating temperature is set. Also, a malfunction indicator is installed in the water heater panel, which gives a certain signal in case of improper operation of the unit (overheating, incorrect thermostat operation, switching on without water, etc.)
Profitability. Ariston water heaters have the lowest energy consumption rates. Average electricity savings are 35%.
Bacteria protection. Very often, water stagnates in heaters, in which bacteria multiply over time. The ECO protection built into the water heater prevents the appearance of bacteria not only on the walls of the device, but also on its internal elements.
High intelligence. The presence of the LCD display makes it possible to set the desired operating mode: day, night and economical.

The lineup

Flat boiler Ariston

The range of water heaters is quite huge and is constantly updated. They are very compact, although they have a large displacement. For a family of four, an 80 liter tank is ideal.

Mechanically controlled square tanks are very common. The only drawback is the unimproved fastening mechanism.

There are also models with a maximum capacity of 100 liters. Such units are able to provide industrial shower rooms. The insulating layer of such models is made of polyurethane foam.

The range of Ariston water heaters can have both an enhanced electronics system and a simple control mechanism. The warranty for volumetric tanks is given on average for seven years. For additional fastening boilers are made of special metal frames.

The cost of a water heater depends on such factors: manufacturer, tank volume, materials of manufacture, power, warranty, additional functions. The prices of electric boilers range from 5,000 to 10,000 rubles. As for gas water heaters, their cost ranges from 13,100 to 23,500 rubles.

Device and specifications

Boiler diagram

Boiler Ariston 80 liters- This is the most common option in home use. It consists of the following parts: housing, container and heating element (heater).

The inner and outer tanks of the device are separated by a layer of heat-insulating material. Two pipes are connected to the heater, which are designed to supply cold and hot water. Together with the heating element, in the heater is located magnesium anode, which prevents the deposition of scale in the device. Experts recommend periodically replacing the anode so that the water quality does not deteriorate.

As for the shape of the body, the 80 liter boiler is basically flat. In order to ensure the heating of water to a predetermined temperature, a special thermostat is built into the water heater.

Specifications:

High durability to corrosion.
Reliable isolation heater.
Overheat protection.
The presence of flashing indicators, which indicate the operation of the device.
Power level adjustment devices.
Maintaining the set temperature in automatic mode.

The boiler socket must always be in a dry place.

User manual:

The boiler comes with a safety valve., which must always be in an integer state. In the event of any chipping or other damage, the valve must be immediately replaced with a new one.
Water heater mains socket must not have a ground contact, otherwise, in the event of a short circuit, the boiler will burn out.
The use of seals is prohibited. and adapters.
It is not recommended to replace the plug water heater.
Water heater power, should occur only on a separate power line.
If you need to replace the power cord, it must be the same brand as the previous one.
Disconnecting the heater from the network should only be done with a two-pole switch.

heating element for boiler

Each boiler is equipped with a heating element. The device and characteristics of the heating element may be different, but most of all for an 80-liter Ariston water heater, a heating element of 1500 W on an oval flange is suitable.

It is made of stainless steel and has a curved shape. Inside the structure there is an oval flange, the size of which is 9.1 × 64.5 mm. The manufacturer of this device is also Ariston.

The heating element has the following specifications:

Power - 1500 watts.
Voltage - 220W.
Warranty - 1 month.

How to clean the boiler?

To clean the water heater, you will need the following tools: knife, flashlight and a metal brush for washing dishes. First, you need to disconnect the heater from the power supply. You also need to turn off the water supply throughout the house or apartment.

Then, you need to remove the cover, which is located at the bottom of the tank, and disconnect all the wires there. All water is drained from the tank through a hose attached to the drain valve. At the bottom of the tank there are bolts that must be unscrewed, while substituting any container.

For thorough cleaning of the boiler, the electrical part is removed from it. You need to take it out very carefully so as not to catch the rubber gasket. The removed electrical part must be cleaned with a special iron mesh, or with a certain chemical agent.

The next stage of cleaning is to remove scale and debris from the tank. To do this, you need to completely inspect the tank cavity (with a flashlight) and clean out all debris with your hand.

The cleaned tank must be thoroughly dried, after which it can already be collected in its original state. Also, before starting work, you should check the tightness of the tank.

If the rubber gasket does not allow water to pass through, then the boiler can be put into operation.

At the time of the arrival of cold weather, more and more often we recall the warm summer and the hot sun, when, fleeing from the heat, we hurried to the air conditioner or took a cold shower. Hot water in the taps helps us to fight the cold, which, alas, appears either in the midst of heating season or does not appear at all.

In some cities, problems with hot water may be all year round, therefore, the best solution in such cases would be a water heater or, in another way, a boiler (boiler - boiler). The difference between these concepts is not so significant, the main thing is that this equipment performs its function and does not allow us to freeze in the winter.

In this article, we will try to figure out what to look for, get acquainted with the features of its purchase for urban and private houses.

Today, the stores offer a huge assortment of all kinds of heating devices, so we will consider the most popular and best option for Russian market(in terms of price and quality) - a line of Ariston water heaters / boilers.

In total, two types of water heaters can be designated - instantaneous and storage. Therefore, to begin with, we will decide which type we need and consider both options.

Instantaneous water heater

The main difference between such units is that they heat the water at the moment when it passes through the heating elements. One of the most significant advantages is more or less compact size due to the lack of its own tank and the heating rate.

If we talk about the minuses, then, perhaps, one of the main ones is the colossal energy consumption of flow devices. "Ariston" - water heaters, the instructions for which say that they can consume from 5 to 30 kW, depending on the model. Therefore, special attention should be paid to electrical wiring and control of energy costs.

For some consumers, in times of austerity, such "requests" are a luxury, so this type of heater is not in good demand in stores. Even almost instantaneous heating of water (7 liters per minute) is incommensurable with energy costs. On top of that, manufacturers recommend installing such equipment only if there is good water pressure.

The pricing policy of flow heaters depends on the selected power and the availability of additional electronics, therefore, in some cases, a flow device may cost a little more than the Ariston storage unit.

Water heaters, the price of which varies between 2000-4000 rubles. (Ariston Bravo, Ariston Slim), are equipped with a standard set of electronics and are perfect for an average family, and models are more expensive than 5000 rubles. (Ariston Fast Evo, Ariston Professional) have more advanced sensors, controls and other useful functionality. They found their application in large families and at special enterprises.

storage water heater

Storage water heaters are exactly those units that are popularly called "boilers". In terms of their energy consumption, they are strikingly different from the type described above and their power varies from 1.5 to 3 kW. Accordingly, the higher this indicator, the faster the water in the tank will heat up. Bright representative accumulative type- Ariston Pro Eco water heater (Ariston Pro Eco PW 15-120, Ariston Pro Eco Slim P 15-80, Ariston Pro Eco ABS V 20-120).

The principle of operation of such heaters is much simpler than flow-through ones. Cold water enters a large tank mounted on the wall, then it is heated to a specified temperature, and at the exit you get hot water.

The heater for the Ariston water heater is located inside the tank, and depending on the model, it (the heater) can be “dry” or “wet”.

"Dry" heating element

In this case, the element is located in such a way that during operation it does not touch the water, and this significantly increases its protection against scale and practically eliminates electric shock.

The only disadvantage is the high cost of a “dry” heating element (1.5-2 times more expensive than a “wet” one), and, accordingly, the amount for its repair also increases.

"Wet" heating element

The “wet” element, as you might guess from the name, is located in the water, which means that the problem with scale comes first for it. This is fraught with the fact that after the formation of scale, the thermal conductivity of the heating element decreases, and the time for heating increases along with energy costs.

A model with such an element is inexpensive, therefore it always finds its consumer, especially since any owner of a boiler can afford to repair Ariston water heaters with a “wet” heating element.

One more important detail of any storage heater - a magnesium anode, which makes it possible to reduce the negative effect of incoming water on the heating element and the walls of the water heater.

magnesium anode

The anode looks like a simple metal pin. Its main functional advantage is that it is uniformly applied to the element. The layer thickness varies between 20-30 mm for Ariston models. Water heaters, the instructions for which clearly indicate the location of the magnesium anode, due to this element are largely protected from the formation of corrosive deposits on the inside of the tank.

If the anode is not installed in your boiler or needs to be replaced, then it is highly recommended to invite a specialist to install / dismantle the element, who can also check the degree of wear and carry out related replacement or repair procedures.

The heating element for the Ariston water heater and the magnesium anode have a specific shelf life, depending on the load and environment, but it is recommended to change the elements and clean the inner walls of the boiler at least once every 14-18 months. Otherwise, there is a high risk of destruction of the walls of the heater by rust from the inside, and one day the tank may simply burst.

But not always replacing the magnesium anode can solve the problem of increasing the shelf life. It's all about our water and its quality, which leaves much to be desired. There are frequent cases when the elements of the boiler simply cannot cope with poorly filtered water and then the whole water heater has to be changed. The average life of the boiler varies within 5-7 years of continuous operation, provided that all necessary repair procedures have been carried out during use.

Water heater capacity

It is very difficult to advise something specific here, because everything depends entirely on the type and size of the room where the boiler will be installed. The main factors are the number of people who will use the appliance and how much you are willing to spend on electricity per month. For example, an Ariston water heater of 15 liters (Ariston ABS Pro R 15, Ariston Slim Eco PW 15) is quite suitable for 1-2 people, subject to infrequent use.

A useful element in your heater will be a special regulator responsible for heating water. In standard models, it looks like a “wheel”, and in more expensive rulers, keys are used along with a display showing the current state of the unit. Any consultant of the Ariston network will help to find out the equipment of the model.

Water heaters, the instructions for which strongly recommend equipping your unit with the ability to turn off (if it is not available), will not turn on at the slightest change in temperature in this case, which will greatly help you save energy and extend the life of the device.

You can make such a switch yourself, you just need to have a little knowledge in this area and acquire an automatic machine (bag).

During a long trip or absence, it is best to drain the water from the boiler in order to avoid breakage or flooding of neighbors. It is not difficult to do this, the Ariston water heater 15 liters (Ariston INOX PW 15, Ariston VLS QH 15) and larger models are equipped with a special hole in the tap.

Boiler capacity

As for the specific volume of the tank, not all buyers represent exactly what volume they need. On the one hand, it seems that the larger the apartment, the larger the volume should be, but on the other hand, one can only partially agree with this. Choosing the maximum displacement, you will rarely use it to the maximum, especially since such a volume is costly and difficult to maintain.

The best option for simple apartments there will be an Ariston water heater of 80 liters (Ariston INOX PW 80, Ariston VLS QH 80, Ariston ABS Slim 80). Its volume is more than enough to take a bath, while getting quite an acceptable temperature.

And if we are talking only about the shower, then 4 family members will be able to use hot water without problems. Moreover, a 120-liter boiler will cost almost twice as much as an 80-liter one, and not every room is suitable for installing a tank of this volume.

Water heater power

On the shelves of company stores, models with a power of 1.5-2 kW are most often found. Such consumption is optimal for standard wiring, regardless of which model you use - an Ariston gas water heater or an electric one.

But in order to avoid any problems, before buying a unit, you should consult with a specialist who, in turn, will check your rated voltage and the actual wiring itself. The average heating rate (80 liters) is about 3 hours to the maximum temperature. A smaller volume (15-20 liters) is perfect for the kitchen and heats up in 1 hour.

Internal coating

The Ariston electric water heater is equipped with two types of coatings - enameled and stainless. There are advantages as well as disadvantages for both types. "Stainless steel" seems to be more serious, but the quality always leaves much to be desired, and the enameled coating is subject to increased wear at high temperatures, so it is not recommended to heat such a boiler above 60 degrees.

Location type

The question regarding the location of the boiler arises in rooms where space is very limited. The most popular units are models with a vertical type of arrangement, occupying the space of a room along the wall. Another advantage of such models is the increase in efficiency due to the longer time for the water to cool.

The horizontal type of boilers is less common. For example, take "Ariston" (water heaters). The instruction to them directly says that these units are inferior to vertical ones in terms of the efficiency of maintaining the temperature of heated water. They cost a little less and have a very specific installation process.

Water heater installation

In most cases, boilers are placed either in the bathroom or in the toilet. Since the weight of the heater can reach 30 kg, the wall, like the fasteners, should be chosen wisely. Repair of Ariston water heaters involves the removal of the unit, therefore, both installation and dismantling are strongly recommended to be entrusted to specialists.

The most difficult thing in the installation process is the wiring, which sometimes has to be additionally lengthened, since the standard cable is almost always short. Otherwise, everything goes pretty quickly and without additional costs.

Convenient connection of water-heating equipment from the company "Ariston" consists in the use of manufacturers of an autoclave special flange mechanism. The basic principle of operation of such a mechanism is based on pressing the gasket under the influence of water pressure. As a result, it is possible to completely eliminate not only the leakage of liquid, but also the formation of watery smudges. To avoid excessive heat loss, fastening electrical models water heater from the company "Ariston" is carried out in close proximity to the point of output.

Water connection

Next comes the connection to the water supply. A scheme is thought out, first drawn on a piece of paper, and then transferred to the walls with real dimensions. Along the lines where the pipes will pass, holes are drilled and clips are installed.

We close the valve at the water inlet, install a tee on the branch closest to the boiler. From it is a pipe to the water heater. A valve is installed on it so that it is convenient to repair the device, a strainer and a check valve.

We lead a flexible hose to the boiler and connect it to the pipe. Usually the input is marked in blue. In the same way, we draw a branch to the watershed point. It is not advised to connect without flexible hoses. On the one hand, it looks better and more reliable, but if there are sudden pressure drops, the tank takes the whole blow.

The inlet to the boiler is marked in blue

After connecting all the nodes, the valves open and all connections are checked for leaks. If they are found, reconnections are made or more tow is added to the threads.

Description of anode rods

The magnesium rod eliminates corrosion of the inner walls of the tank, and also softens the scale that forms on the heating element during the operation of the water heater. It is a magnesium alloy rod on a metal threaded stud and is screwed to the heating element flange, together with which it is inserted inside the water heater tank. The hole thread diameter ranges from M4 to M8 depending on the size and weight of the magnesium alloy on the stud. The larger the size and weight, the thicker the magnesium anode stud. The diameter of the magnesium anode is from 14 to 25 mm. The length of the magnesium part without the stud is from 140 to 660 mm.

Operating principle

The water entering the water heater contains soluble calcium and magnesium bicarbonates, which are present in it in the form of Mg2+, Ca2+, HCO3- ions. Magnesium is the first to react with water, since it is more active than iron and binds free oxygen formed during heating due to a multiple increase in the amount of Mg2+ cations. When the anode is installed in the tank, not hard scale (CaCO3) is formed, but soft scale (MgCO3 or Mg(OH)3), which is easier to remove when cleaning the water heater, or which itself falls to the bottom of the tank during the operation of the water heater due to thermal expansion or contraction of the heating metal element. The anode will dissolve over time, so it is advisable to check or replace the magnesium anode once a year or follow the water heater manufacturer's instructions.

Is it necessary to install a magnesium anode in a water heater?

Modern boilers have tanks made of stainless steel, with titanium, glass-porcelain, enamel coating. In this case, the tank corrodes at the welds and begins to leak over time, so it is necessary to regularly replace the magnesium anode. If it was not originally in the water heater, then it must be installed in the case when scale forms on the heater. In this case, the manufacturer most likely performed welding using a special technology or even made the tank one-piece, without welds. Without an anode, hard scale is formed, which has a lower thermal conductivity. This increases the heating time and the amount of energy consumed, reduces the efficiency, there is a constant overheating of the metal of the heating element. In the end, this leads to its rupture and failure. Therefore, timely and regular replacement of the anode will allow your water heater to work for many years.

What to look for when choosing a magnesium anode?

The main selection criterion is the diameter of the thread on the stud so that the anode can be fixed on the heating element flange or nearby, if such fastening is provided. The second criterion is the length, since meter ones, for example, simply may not fit. The next criterion is thickness. Anodes with a large diameter can touch the heater tubes, although in this case the plate with the mounting hole can be bent. The next criterion is the length of the stud. This choice is rare, as certain electric heaters require a long stud to keep the heating tubes out of the way.

Advantages of Ariston technology

Like all Ariston appliances, the water heaters of this company have a lot of benefits:

The first of these can be called stylish design which helps to decorate any interior. Moreover, each of the models is created in accordance with the latest technologies.
Ariston 80 water heater is different longest service life . This effect was achieved due to the fact that internal walls storage tank covered with a layer modern material which protects the tank from plaque and rust.
Built-in latest dividers, prevent mixing of already heated and cold water . This allows you to keep the temperature of the liquid. Also, the Ariston heater is protected from overheating, thanks to built-in temperature control sensors.
Presence of a safety shutdown device , which is triggered at moments of a sharp change in voltage.
Using Ariston water heaters, users can significant savings on gas or electricity consumption . This is facilitated by the presence of thermal insulation, which keeps the water hot for a long period of time.
Many models of water heaters equipped with bacteria protection which makes it possible to use purified water. If there is no water in the system, then you do not have to worry that the water heater will turn on, as it is equipped with special protection.

Repair

If we break down the repair actions of the units into several stages, they will be as follows:

It is necessary to diagnose the type of failure.
Determine the fault
Replace the failed assembly or part.

Features of water heaters "Ariston"

We are considering the repair of the Ariston electric boiler. Models from 50 to 100 liters. One of the advantages of the models of this company is the use of a classic autoclave flange. This solution does not allow water to flow through the gasket. The gasket is pressed against the pressure of the water in the water heater. The larger it is, the greater the tightness. But Chinese manufacturers have learned to fake this gasket, therefore, when purchasing it as a replacement, you need to look for a “native” one, avoiding fakes.

Boiler "Ariston"

The next feature is that the heating element is equipped with an extended knife contact, so heating elements from other manufacturers are not suitable.

The water heater is supplied with a magnesium anode.

Examination

Before starting the repair of Ariston water heaters, it is necessary to check whether there is electricity in the house and whether the water has been turned off. Often this factor misleads inexperienced users.

The next step is to check the correct connection to the mains and cold water. If these positions are maintained correctly, then the problems should be sought in the following:

The circuit breaker is off.
The automatic safety device has been activated.
The heating element burned out.
Electronics broke.

Replacing the heating element

If you find out that the heating element has burned out, then it needs to be replaced. Try to repair the Ariston water heater with your own hands.

Self repair

For this you need:

Disconnect the boiler from the power and water supply.
Unscrew the two screws and remove the protective box.
Turn off the power that is directly connected to the heater.
After unscrewing two more screws, remove the cover of the water heater.
Remove temperature sensor and thermostat.
Remove the non-return valve from the water supply pipe and drain the water from the boiler.
Unscrew the fixing nut with an adjustable wrench and remove the fastening on the bar to which the flange is attached.
Move the heating element inward, unfold and pull out. Do this carefully so as not to damage the flange. Don't forget to put a container under the flange, as water will still flow.
Replace the heating element or clean the flange and tank from dirt. It is not recommended to remove scale from the walls, as this is an additional protection of the tank from corrosion. Remove only the scale that has crumbled inside or is easily cleaned with a rag.
Replace or clean the magnesium anode. It spins next to the shade.
Replace all parts in reverse order.

At the end of the assembly, check the tank for leakage. If it leaks, replace the gasket.

When replacing the flange, it is important to put the same design as it was. Otherwise, the gasket may break, and the boiler will start to flow.

A heating element

If you do not regularly clean the water heaters, then the anode and the heating element will collapse, despite the good adaptation of Ariston products to our water. Therefore, it is so important to regularly inspect and repair the Ariston boiler, you can do it yourself.

Fake Parts

Connecting the boiler Ariston

It is better if this work is carried out by specialists. The rules to be followed when installing the device are given below:

It is necessary to inspect the safety valve, which should not have visible flaws. If they are, then the damaged part should be replaced.
Plastic dowels are used for driving screws.
Be sure to check all grounding elements.
The electric heater requires a separate power line to operate. The use of extension cords is strictly prohibited. The socket is placed in a non-humid place.
In operation, you must use the plug that came with the kit.

The water heater Ariston 80 performs the following functions :

Turn on/off . After switching on, the whole system starts up, which is due to the lights on, the temperature of the water in the boiler will be displayed. If the indicators are not displayed or flashing, this indicates a system shutdown.
Water heater ariston abs vls 80 has power level adjustment function , which makes it possible to set the necessary indicators.
Water heater ariston abs vls pw 80 allows you to use antibacterial function , which can be activated or deactivated by holding the "power" button for 5 seconds.
Possibility to adjust the temperature using the "+" or "-" buttons in the range from 30o to 75o; The set values are not fixed. After switching on again, the values \u200b\u200bmust be set again. Standard temperature values are 75 °, power - 1500 watts.

Water heating

Depending on the volume of the tank, the time of the first heating will differ. It takes about an hour to heat 30 liters of water to 65 degrees, 50 liters two hours, and 80 liters three hours. Also, the time depends on the heat of the incoming water and the power of the apparatus. In winter, the water comes in cold and it will take longer to warm up.

Boilers with more powerful heating elements spend less time and more electricity on primary heating. For example, Ariston Platinum SI 80 H with a volume of 80 liters and a heating element of 1.5 kW heats water from 20 to 65 degrees in 3 hours and 6 minutes.

For two people, a volume of 30 liters is enough, fifty is enough for a family of 3 people. An eighty-liter model should be enough for 4-5 people living in the room where the water heater is installed. Also, the consumption largely depends on the habits and purposes of using hot water.

The system for using the heater is very simple and straightforward.

The device may only be installed by qualified personnel. Before installing the tank, it is necessary to check the serviceability of the electrical wiring. Specialists must make sure that the voltage in the network corresponds to the permissible voltage for the tank, specified in the instructions for use of the device. The use of adapters or extensions is excluded. It is not allowed to connect additional electrical appliances to the same electrical line. The outlet must be dry and away from water sources. If the power cord becomes damaged over time, it can only be replaced by a specialist.

So, the tank is already connected, how now to turn on the Ariston water heater ?. Instructions for use will help you connect the heater.

First you need to turn off the hot water supply in the apartment. Otherwise, the contents of the boiler will flow into the riser. Despite the presence of a non-return valve, turn off the water.

Open the faucet, wait until the water has completely drained. When the liquid stops flowing, close the valve.

See also: How exactly does an instantaneous water heater work?

Cold water and heated water enter the boiler and back through two pipes. On the tank, they are marked with a blue and red label, respectively. These mixers on both pipes need to be opened. First turn on cold water, then hot. If you forget to turn on the hot water faucet, it will flow through the riser to the whole house.

When the air comes out of the device, and the liquid flows in an even stream, the boiler can be connected to the power supply and the desired program can be selected. Do not block the cold water pipe, the supply to the boiler is regulated automatically.

After five minutes, check the water in the tap, its temperature should increase. If so, then you did everything right.

There are also compact water heaters. Mounting such devices will not be difficult. They are installed in place of the old crane. After installation, the tank must be connected to a pipe through which cold water flows. Then turn off the hot water faucet and plug the appliance into the outlet. Turn on the water and you're done. To install such heaters, it is still better to contact specialists.

Any heating tank must be connected to a separate outlet, which is removed from sources of moisture.

When the boiler is finished using, it must be turned off. How to do it? Unplug the cord from the tank. Wait for the water in the tank to cool down. Close both taps, one of which supplies water to the tank, and the second releases hot water. After that, open the hot water riser.

If the boiler is used from time to time, then it is not necessary to drain the water from it. Water contributes to the fact that the parts in the device are less corroded. Drain the water just before using it again. When you do this, rinse, dial clean.

If a situation arises when the boiler needs to be emptied of liquid, then this can be done using the check valve installed on the device.

Be careful! When the tank is empty, its inclusion is strictly prohibited!

In order for the Ariston water heater to serve you for a long time, it needs care. Every six months it should be cleaned to protect the heating element from breakage. Any malfunction is best repaired by specialists.

To notice this, pay attention to the following:

water heats up noticeably longer;
hissing is heard during operation of the device;
the heater turns on and off more often.

With proper operation and timely care, the unit will last a long time, since Ariston uses only original spare parts for its devices. Heating elements are made of high-quality copper, a special system protects the device from overheating and freezing. Models are characterized by a flat shape, easy installation. Tanks are produced in volumes of 30, 50, 80 and 100 liters. The devices have a water purification system from bacteria. The displays are functional and easy to use.

Do-it-yourself Ariston boiler repair

Repair work related to the elimination of breakdowns in gas appliances requires the involvement of qualified specialists, and the repair of an electric boiler can be done independently.

Major mechanical failures are most often manifested by tank leaks., from which water begins to ooze or drip during operation. The cause of this failure may be corrosion in the weld areas or a malfunction of the reverse protection system of the valve, which operates and performs an emergency reset. In this case, it is necessary to eliminate the excess level of water and air pressure by means of a reducer. Any depressurization of the storage tank will require the purchase of a new tank. If such a defect is insignificant, then it is enough to replace the sealing gasket.

A relatively inexpensive undertaking is self-replacement some electrical parts, including heating elements, bimetal thermostats, sensors or switches. In case of prolonged heating, noise or hiss, as well as in the event of an ABS system shutdown protection, a replacement of the heating element is required, the average service life of which does not exceed five years. Replacement is carried out after de-energizing the device, draining the water and removing the flange.

It is very important to systematically check the magnesium anode, which is a consumable item and is intended for effective protection the inner surface of the tank and the heating element from corrosive changes. When the anode is thinned by ½ of the original volume, a mandatory replacement is carried out

The heating element is able to last much longer if the so-called “dry” heating element is installed in the structure.

Installation

Do-it-yourself Ariston is a simple matter if you carefully read the instructions and follow its instructions. Of course, you can invite specialists who will do everything quickly and efficiently. The only “but” is the price of this service. For example, in Moscow it is from $100. Meanwhile, having minimal skills in working with plumbing, you can cope with this task in just 2-3 hours. Considering that you will spend some amount on Consumables, the net savings will be approximately $60.

Evaluating the pros and cons, consider the risk of flooding the neighbors from below, if something goes wrong, measure your strength. The advantages of self-solving this problem include:

saving time and money;
acquisition of skills that you will need in the process of operating the water heater.

Access to the storage water heater (boiler) must be absolutely free, and the wall for fastening must be strong, capable of withstanding double the weight (with a unit capacity of 50 liters, calculate the load of 100 kg). Determine the condition of your electrical wiring: is it capable of handling a significant additional load? For example, for a water heater of 2000 W, there should be a copper wire cross section of 2.5 mm². Keep in mind that if you have old water pipes in an apartment, sometimes you have to first replace them and only then connect the boiler. Find out how much current your electricity meter is designed for. If less than 40 A, you will have to replace it.

Turning on

If you are turning on the boiler for the first time, you should do the following:

We examine the inlet pipes to the water heater and find the check valve. If the normal pressure is exceeded, water will pour out of it. Therefore, you should either substitute a small container under it, or connect and bring the tube into the sewer.
We collect a tank. We open the valves at the inlet and outlet of water from the device. To do this, turn the handle of the taps 90 degrees counterclockwise. Open the hot water faucet. We are waiting for the container to be filled. If water starts to flow, this means that the Ariston boiler is full.
It is advisable to visually inspect the pipes for leaks. If water drips somewhere, it is necessary to turn off the water and call specialists to fix the breakdown.
We turn on the device in the network. To do this, either insert the plug into the socket, or turn on the machine to which it is connected. electrical cable. The machine may be located near the installation site or in a switchboard.
Set the desired water temperature. It is recommended to set the level of 60-65 degrees. At higher temperatures, scale actively accumulates, and at lower temperatures, harmful bacteria can begin to multiply.
The temperature can be set with a mechanical knob, as in the Ariston SG 30 OR model, or with buttons on the control panel, as in the Ariston VELIS EVO PW model.

After that, it remains to wait until the liquid heats up and start using hot water. For convenience, you can mix cold tap water with warm water from the boiler to achieve the desired temperature.

Water heater Ariston

It is very important to prepare in advance all the tools and consumables for the work. Before starting installation, make sure you have the following tools: .

Tools for mounting storage water heater.

roulette;

Installation

Installation of the water heater "Ariston can" is done by hand.

Installation of the Ariston water heater must be carried out in strict accordance with the instructions.

Installation instructions for the Ariston water heater, of course, are included with the purchase of the unit.

It is necessary to check the outlet and test the voltage in the electrical network. The socket must be grounded and have a separate wire from the shield.

Fastening

Since the weight of the device will be quite heavy due to the large amount of water, the wall on which it will be installed must be strong. The bolts with which this structure will be attached must also be strong. It is better to use metal fasteners: hooks, bolts, screws, with a diameter of 10mm. The connection of the Ariston water heater should be close to the place of hot water supply so that there is no unnecessary heat loss. It is necessary to clearly mark the place of attachment of the water heater using a level and a tape measure. Make sure that the load is evenly distributed, there are no distortions. Using a drill, holes are drilled in the wall, to which brackets and holders are attached, on which the boiler is hung.

Some models are installed on the floor. In this case, the symmetrical installation is adjusted by the feet of the appliance.

Connection to the water supply system

The hoses and other connecting elements used for connection must withstand the design pressure and temperature of about 80 degrees. When connecting to a water supply system, it is best not to connect two different metals to each other, such as copper and steel (in pipes). To do this, you need to use a dielectric adapter.

With the help of a valve included in the device, a pipe for cold water is connected. The hot water pipe is connected using a pipe. Your task is not to confuse these two inputs when connecting the Ariston boiler.

Start installation with a cold water pipe, it is marked in blue. A sealing tape or tow is wound on the pipe. If you take tow, then it must be lubricated with a special paste. Then the tee is screwed on. There will be a relief valve at the bottom of the tee. It is installed in an upward direction. This valve will control pressure and superheat. On the side of the tee we put an emergency drain valve. You will use it if you need to completely drain the water from the boiler.

The shut-off valve is placed at the bottom and the boiler is connected to the water supply through an adapter.

Also, through a shut-off tap and an adapter, a connection to hot water is made.

The correct scheme for connecting the Ariston water heater to the water supply is shown in the video:

Electrical connection

Only after the connection to the water is made, we connect it to the electrical wiring. Since this unit consumes a lot of electricity, the wires must also meet the requirements.

Connecting the Ariston water heater to the mains is as follows:

Disconnect the water heater from the electrical network.
The power supply wires are connected to the screw terminals of the thermostat.
Be sure to observe the phases when connecting: - L, A or P1 - phase wire; N, B or P2 - neutral wire.
Connect the ground wire to the clamp on the boiler body.
Connect the test lamp terminals to the terminals.
Press the thermostat button.
close lid
Before switching on the power supply, it is necessary to check the filling of the boiler with water.
Turn on power.

Scheme of connecting the boiler "Ariston" to electricity through a double circuit breaker:

Boiler connection

The electric wire for the boiler must pass through the wall or be hidden in a corrugation made of non-combustible material. The connection cable must be three-core, preferably copper. Installation of the Ariston water heater must provide for grounding. Grounding is not done on metal objects and pipes, such as sewers, plumbing, and so on.

Beginning of work

Before starting work, you should once again make sure that the flange is exactly in the center. If it is slightly off to the side, install it correctly (loose or tighten). After filling the tank with cold water, open the hot water outlet cock on the boiler to allow excess air to escape, then close it.

When you turn on the heating pressure on the body of the water heater, the lamp should light up. Sometimes during operation, the cold water hose heats up. In some Ariston models, the temperature can be adjusted with a special knob connected to the thermostat with a screw. Economy mode is marked on the unit with the letter "E".

In the event of an unexpected breakdown or malfunction of the new water heater, you can contact the warranty repair shop in your city. The usual warranty period for the Ariston boiler is 1-2 years, depending on the model (the same as for the Termex, Bosch or Nova Tek water heater). If before the expiration of this time you tried to open and repair the unit yourself, then most likely you will be denied free warranty service. Keep the warranty card issued by the store until the end of the warranty period.

The storage water heater from the company "Ariston" - the unit is quite simple to operate and reliable. If you strictly follow the instructions during installation and when further use, it will serve you faithfully for more than one year.

Boiler installation

Accumulative water heaters heat water for a certain time in special tanks from 10 to 150 liters and more. In small city apartments, most often they put boilers of 50 or 80 liters. Fastening to a fragile wall (for example, drywall) is excluded. There is no fundamental difference in installing a small or large tank, except that the larger the unit, the more powerful the fastening elements.

Scheme of the storage water heater.

Break the work into several stages. The main and most important stage is fixing the boiler to the wall. If the container is horizontal, it is advisable to attach it higher, under the ceiling, if it is vertical - at the level of the person's head or chest. Under the boiler, the floors must be waterproofed in case of leakage.

You need to work carefully, avoiding scratches and damage to the outer surface of the unit from tools. It must also be borne in mind that the electronic control unit of the boiler does not have an independent power supply, in case of any power failure, the settings will fail and a restart will be required.

Use bolts, hooks, screws with a diameter of at least 10 mm. Using a tape measure, mark the level of the attachment points. Make sure that all dots on reverse side of the unit provided for installation have been used, do not skew. Drill holes with a drill, then attach brackets and holders to them, on which the boiler is hung.

Instructions for the water heater Ariston 80 liters and a number of other issues regarding this equipment will be discussed in our material. We will talk about the main advantages of Ariston equipment, the device, the rules for connecting and operating the units.

Ariston products are in rather impressive demand in the domestic market. Many people choose this particular manufacturer when buying a water heater. What is the reason for this? The advantages that a boiler of 30, 50, 80 or even 100 liters carries.

When choosing a boiler for 30, 50, 80 or 100 liters, you should rely on the number of users and the number of consumer points. If this is a small family of 2 people, 30 or 50 liters is enough. But for families of 3 people or more, it is better to take a boiler for 80 or 100 liters.

Now about the benefits of Ariston.

Attractive, modern design Ariston. Many are guided not only by the efficiency of the boiler, but also by appearance, since the unit will be located in a conspicuous place. In this regard, Ariston appliances are able to decorate the interior, and not only provide hot water.
Long service life. Ariston boilers with a volume of 30, 50, 80 and 100 liters have a factory warranty for several years, but in reality they can serve for more than ten years. This was achieved through the use of special materials that cover the inner walls of the boilers. They protect against scale, rust, plaque.
Modern dividers are used. Due to them, cold water does not mix with heated water. Therefore, when heated, not even a large number water in the boiler for 30, 50, 80 or 100 liters, you can use hot water, and not wait for the entire volume of the water heater to heat up.
Protective mechanisms of the water heater. They work very efficiently, responding to potentially dangerous power surges. This largely ensures such a long service life of Ariston equipment, which we talked about earlier.
Antibacterial protection. With its help, you can safely wash under water from a boiler that has been operating in your house for more than a year, without fear of water pollution.
Protection of the water heater from an empty tank. Everyone knows that it is impossible to turn on the boiler when the tank is empty. Otherwise it burns out. But there have been many precedents. Unlike them, Ariston water heaters are equipped with a special mechanism that does not allow the device to be put into operation if the tank is empty.

Device

Now let's see what components a modern Ariston water heater consists of. In fact, regardless of the tank of 30, 50, 80 or 100 liters, the design remains identical. Only differences are in the size of the elements, their characteristics, capabilities.

Water heater body. This is the outer shell that hides all the internal components. The designers did a great job making Ariston boilers not only effective, but also very beautiful;
Internal capacity. Or a tank. This is the same tank where cold water is poured from the water supply system;
TEN. A heating element that provides heating of the incoming cold water to the boiler. In models with a volume of 30 and 50 liters, one heating element is used, and water heaters of 80 and 100 liters can be equipped with two heating elements at once. This contributes to faster heating of a large volume of water;
Thermal insulation layer. An effective heat-insulating layer on Ariston boilers contributes to the long-term preservation of the temperature of the heated liquid;
Pipe and splitter. These devices are responsible for the separation of heated and cold water, as well as the supply of hot liquid to taps, shower heads and other consumers;
magnesium anode. This is an indispensable element of any boiler. Its task is to prevent salt deposits on internal surfaces. Considering the quality of the water entering the boiler from the centralized water supply, the developers used an improved efficiency anode to cope with less than perfect water. It is not uncommon for the repair of Ariston water heaters to involve the replacement of the anode or heating element;
Temperature controller. It is necessary in order to turn off the operation of the heating element when the water temperature reaches the user-set mark;
Thermal relay. An important unit that contributes to the automatic inclusion of the heating element in a situation where the temperature drops below a predetermined mark;
indicator lamp. This voltage indicator allows you to monitor the operation of the boiler;
Thermometer. All Ariston water heaters are equipped with built-in thermometers. With their help, the user can monitor the change in the temperature of the heated water.

Useful Features

Having chosen a boiler from Ariston for 100, 80, 50 or 30 liters, it will be useful to know about the capabilities of this equipment.

Turning on and off. A working boiler is determined by luminous indicators;
Power adjustment. The user himself sets the parameters on which the equipment works;
antibacterial mode. To turn it on or off, hold the "Power" button for 5 seconds;
Temperature change. You can change from 30 to 75 degrees by pressing the + or - buttons.

Installation instructions

Let's be honest, the installation of boilers for 30, 50, 80 and 100 liters is best left to a specialist. But if you decide to do everything yourself, then we recommend that you follow certain rules.

Check Status safety valve. If it has visually noticeable defects, be sure to replace it with a new one.
When installing the screws used to install the boiler, be sure to use plastic dowels.
Make sure that the grounding elements are installed correctly.
Use only a separate power line to connect the boiler. No extensions. Choose waterproof outlets.
To connect Ariston water heaters Use only the plug that came with the kit.

Operating rules

In order for your Ariston boiler to work for more than one year, and always efficiently heat all 30, 50, 80 or even 100 liters of water, follow certain recommendations for operating the equipment.

Check the presence of liquid in the container before each shutdown and restart of the equipment. Only when the tank is full can power be applied. Despite the presence of a protective system in Ariston, ignore this advice do not recommend.
If the boiler cord is damaged, the replacement is carried out exclusively with a component of the same manufacturer and with the same characteristics. It is better to buy accessories for Ariston boilers in branded or specialized outlets.
When planning a long shutdown of the water heater, be sure to drain the old water according to the instructions for your boiler model, then turn off the water supply tap from the water supply system, and then turn off the power.
Periodically, your Ariston will need a system cleanup. Here we recommend using a warranty and post-warranty agreement so that this procedure is performed by specialists. You can learn all the subtleties, in order to then do the work with your own hands.

Ariston boilers are time-tested water heaters that rightly occupy their high positions in the market.

Temperature setting:
The water heating temperature can be adjusted using the temperature controller, if the water heater is switched on. Temperature control is carried out in the range from 300C to 750C. The water heater will maintain the set temperature automatically.

7. Moments that need attention

1. At the first start-up of the water heater, as well as at each start-up after switching off, make sure that the water heater is filled with water and only then connect it to the network.
2. If the power cord is damaged, it should be replaced with a special cord. This cord can be purchased from an authorized service center.
3. In winter and in cold areas, when the heater is not used for a long time, drain the water from the heater. To do this: close the cold water supply valve, open the drain valve (if there is a mixer, turn its regulator to the maximum temperature position), close the sludge removal drain (be careful not to scald), then drain the water.
4. Socket outlets must be properly grounded.
5. Clean the heater periodically during operation. Sequence of actions: disconnect the water heater from the network, shut off water faucet, open the drain valve by turning the handle, open the drain hole (be careful not to scald) and drain the dirt. It is advisable that this work be done by a qualified specialist.
6. If there is heavy scale formation in the heating elements or a large amount of sediment, remove the heating elements and clean them. When reinstalling them, observe the following: the bolts must be tightened evenly, without significant application of force, the fixing support must not be tilted. The power supply can only be connected after filling the water heater with water.
7. If the heater is not used for a long time, turn off the cold water supply tap and disconnect the water heater from the mains.
8. If the water pressure exceeds 6 bar, water drops or leaks may appear on the outlet of the safety valve.
The rare appearance of water droplets on the drain hole of the safety valve indicates normal operation of the heater.
The frequent appearance of water drops on the drain hole of the safety valve means that the water pressure is too high. In this case, it is necessary to install a reducer on the cold water supply pipe to reduce the pressure, which should be located at the maximum distance from the heater.
To drain the resulting water droplets, a drain pipe can be used, the end of which must point downwards and not be closed.
9. Before contacting the service center, make sure that the malfunction of the device is not related to the shutdown of the cold water supply, power supply, etc. If the water heater is not powered, the water overheating safety thermostat may have tripped. In this case, contact an Authorized Service Center. Have your warranty card ready. It will be needed by a service specialist during the repair of Ariston.
