For the convenience of getting hot water In the room, regardless of central heating, storage electric water heaters - boilers were developed. The range of electric heaters is very wide. Today we will take a closer look at the instruction manual for one of them, namely, the Ariston water heater.

Your task is to use it correctly

Having purchased Ariston electrical equipment for the home, do not forget to carefully study the instructions and always have it "at hand". Follow instructions should not in any way be skeptical and underestimated, since it is, first of all, your safety. Even if you accidentally lost the instructions from the device, you can get its electronic version specifically for your Ariston model on the official website of the manufacturer. People who create electrical devices, test them, test them, put the maximum useful information to the manuals for use and operation with the only important goal- so that you use them correctly. The same article will discuss General requirements and introductory moments.

Boiler diagram Ariston 50

Boiler designs have approximately the same construction scheme. It has a body, a water tank (the boiler itself), and a heating element (otherwise a heating element, sometimes there are several of them in the configuration). Be sure to install a magnesium anode next to the heating element, which prevents the formation of scale. The boiler itself from the outside and in its inner part has an insulating layer.

Two pipes lead to the water heater - one for supplying hot water, the second for cold. Boiler bodies can be cylindrical or flat. The boiler tank can have a different capacity - from 30 to 100 liters. The basic principle of operation of the boiler is to heat the water in the tank and maintain its constant temperature, set by a person, depending on the need.

What you need to know about Ariston boilers

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

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 according to 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 compact tank, designed for different volumes - 30, 50, 80, 100 liters. Boilers are of direct heating (they themselves heat water using gas or electricity) and indirect (such devices are located near the 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:

About installing an electric water heater Ariston according to the instructions

Before installing the water heater, make sure the wiring can handle the added power. It is especially important that the outlet to which you are going to connect the device is grounded and not in contact with water. The power supply to the water heater must go from the shield on a separate cable. When choosing a place to install an electric water heater, consider its weight together with water in three times the size and the strength of the walls.

For fastening, hooks with a size of at least 15 mm are required. It is recommended to install a water heater in the immediate vicinity of the displacer, which will also reduce heat loss when water is supplied to the point of analysis. 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?

If the water is hard, you must additionally install a filter, otherwise the water heater will quickly fail. It is impossible to install the device in rooms, the temperature regime of which may have a negative indicator, to exclude the influence of factors dangerous for the device - dampness, frost, direct sunlight, dust and insects. Maximum avoid splashing water, steam on the body of the device, that is, it is not recommended to install it directly above the bathtub.

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

Only branded parts

All parts of the water heater, when first installed, must be in good condition. This is especially true for the safety valve. If damage is noticeable, the part should be replaced with a similar one. In no case do not use adapters or extension cords, do not replace the water heater plug with another one. Separate power line required to power the boiler. If the power cord is damaged, replace it with a similar one.

When turning off the electric heater, use a two-pole switch, the gap between open contacts is from 3 mm. Also pay attention to the fact that the pipes to which the water heater pipes will be connected have withstood temperatures above 80 degrees Celsius and the maximum working pressure.

Precautionary measures

If you know that you will not 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 tee drain valve. A magnesium anode that wears out 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.

Prevention

With frequent use of the boiler, the first technical inspection should be carried out in six months or a year. Every 3 months it is recommended to drain the contents of the tank in order to remove sediment, which prevents heat transfer and reduces the efficiency of the heating element. It is also recommended to replace the magnesium anode after a year of operation of the device. Never ignore the error codes that appear. You can see in detail what each of them means in the instruction manual.

Comfort modern apartment impossible without warm water. But public utilities are in no hurry to make our lives easier and more enjoyable. Therefore, it is necessary to independently take care of the presence of comfort in your home. Hardware stores offer us a huge selection of water heaters. Which one to stop?

If your home is not suitable for installation geysers, then opt for Ariston boilers 80 liters. This is the famous Italian trademark, which has become a leader in the design and manufacture of household appliances. In order to dispel your doubts, we will explain the boring instructions in an accessible language.

Features of the water heater

A characteristic feature of water heaters is built-in tank. Water accumulates in it, keeping the temperature set by the program. Such a model will become relevant for those who from time to time have problems with hot and cold water supply. Eighty-liter tank of the model, as indicated by the instructions, perfect option for a family of three. Wash the dishes, take a shower, bathe the baby.

The structure of the boiler resembles a thermos: in it, the liquid not only heats up, but also retains heat. The heat-insulating material occupies the empty space between the body of the water heater and the tank. Schematic representation The manual clearly shows this to us. Thanks to him, energy is saved: after all, you do not have to constantly maintain the temperature.

The inner tank of the water heater "Ariston" 80 liters is made of quality steel, which has an increased resistance to corrosion processes. The fact is that under the influence of aggressive environments (constant high temperatures, humidity, changes in water level), metal components suffer first of all. Therefore, the Ariston engineering bureau developed a special alloy, which received maximum resistance to rust corrosion.

The heating element of the water heater (TEN) has a reliable insulation. The feature of the model is heating element material - alloy, which may contain:

  • copper;
  • stainless steel.

Thermal power is increased by a brass flange.

One of the main parts of the Ariston boiler 80 liters is a magnesium anode. It is made of a special alloy and is attached next to the heating element. Its function is to protect the walls of the water heater tank from rust, to reduce the amount of scale. If you do not start fighting corrosion in time, then over time it will begin to corrode the metal walls of the container and, as a result, it will begin to let water through. Scale layers on the heating element will increase the heating time, which will lead to waste of electricity, and even breakage of the element. Entering into chemical reaction With aggressive environment, the anode shields the internal parts from negative impact. You, of course, will not read this in the instructions for the device, but to obtain general information healthy.

Intelligent control system in which even a schoolboy will understand. The ergonomic design allows you to place the Ariston 80 liter water heater models in a horizontal position. In addition, the equipment is reliably protected from overheating, high pressure.

Water heater installation

So you bought a boiler and carefully study the instructions. Remember that in order for the water heater to work reliably, all installation actions should be entrusted to the service center employees. In case of an error at self installation, warranty obligations technology does not apply.

Water heater: control system

Before turning on the water heater, you must make sure that there is water in the tank.

When the boiler is connected to the network, within one or two seconds, the temperature readings will be displayed on the screen of the water heater control panel. The instruction indicates that if the numbers flash, then this means only one thing - the device is still turned off. Click on the "On / Off" button (in the upper left corner) to start the technique.

There is a power control button on the remote control. It can be used to adjust the strength voltage from 2500 W to 1500. This function allows you to increase or decrease the time for heating water.

The temperature setting is activated by holding the button (plus or minus) for a few seconds. The range ranges from 30C to 75C. After installation, the water heater remembers the program, working in the specified mode. The instruction says: if the device is turned off, all settings are reset.

If you have not read the instructions to the end, then you do not know about the very convenient function of the water heater - protection against bacteria. Hot water is an ideal breeding ground for all kinds of microorganisms. And heat kills them. By enabling this option, you force the technician to increase the degree above 65, that is, to a level where microbes cannot exist, multiply. Once a month is enough for your water heater tank to be freed from all evil spirits.

Possible breakdowns

Water heaters "Ariston" 80 liters belong to the technique with a high degree of reliability. However, as sad as it is to say, damage does happen.

According to the repair service employees, the most “popular” breakdown is the failure of the electronic scoreboard. Do not panic, flipping nervously through the instructions, this does not affect the overall operation of the water heater. Experts also recommend using not the maximum temperature, but within 60C.

Heating elements for boilers "Ariston" 80 liters need to be changed from time to time. No matter how powerful anti-scale protection is, the quality of our water still does not improve. Therefore, after two or three years, your heating element will turn into a small pebble. If you do not open the water heater, then you can determine the presence of this unpleasant feature by increasing the heating time.

The instructions for the water heater indicate the marking commonly reported errors:

  • E2 - an attempt to turn on the boiler with an empty tank;
  • E3 - temperature sensor depressurized, short circuit occurred;
  • E4 - in case of heating water up to 90C.

If you see any of the above on the water heater control panel, you need to contact the service center.

So, we examined the main characteristics of one of the popular models that Ariston water heaters represent 80 liters. With proper operation, compliance with all the rules of the instructions, this reliable device will serve you for many years. And a wide network of official service centers will nullify discomfort in the event of a breakdown.

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 rubber gasket does not pass water, so the boiler can be put into operation.

Each property owner wants to equip his house with an autonomous plumbing system that supplies hot water. Thus, you can use hot water all year round, regardless of the season or schedule of the centralized installation. The 50-liter Ariston water heater is in great demand because it has a wide range of advantages.

A water heating boiler is a specialized device that performs the function of heating water with further stable maintenance of the temperature regime for a long time. What exactly is interesting about the 50-liter model and what models the manufacturer offers - in our article.

Equipment classification

Units of this manufacturer are divided into several classifications based on the following parameters:

  • Water heaters are accumulative, flowing, indirect;
  • Floor or wall type devices;
  • Equipment that runs on natural gas or electricity.

Each device has a specific heating system, a control unit, fasteners corresponding to the classification and other additional options.

Purpose of the tank

Household units powered by electricity are often used during the period when the water supply from the centralized pipeline stops. For short-term use, small wall-mounted storage water heaters are purchased. At competent installation, the device will provide the house with a supply of warm water, which can be used to fulfill all household needs: washing dishes, wet cleaning, washing things or taking a shower.

In private cottages in combination with gas boilers use gas or electrical type heaters with large storage tank dimensions. In this case, the Ariston boiler is used year-round.

Rating of the best Ariston water heaters for 50 liters

The Italian company produces many modifications of water heaters, differing in the type of heating, volume, shape and other important technical specifications. We offer to consider the most popular models.

Ariston (50 liters) VELIS INOX

The wall-mounted device can be installed in a horizontal or vertical position. It is characterized by relatively low cost and medium volumes. The flat shape of the unit allows you to mount equipment not only on the open area of ​​\u200b\u200bthe wall, but also in a niche.

The Ariston water heater is equipped with copper heating elements and power up to 2500 watts. In addition, the device has a protection system located on the electrical cord and a fuse that prevents unexpected start-up of devices with an empty tank.

Short description:

Ariston ABS VLS INOX QH

The external parameters of the model have significant similarities with the previous modification. The unit is equipped with automatic equipment that quickly heats up and thoroughly filters the liquid. In addition, the device regularly monitors temperature regime the coolant itself, preventing the electric water heater from overheating.

Ariston ABS VELIS PW

The inside of the equipment is covered with a protective layer developed in accordance with the innovative AG + technological scheme. The equipment is equipped with a system of protection against bacteria and two heating elements.

When assembling the device, a special welding technology was used, providing a strong and monolithic connection, which eliminates the possibility of leakage.

Ariston ABS PRO R SLIM

The cylindrical shape of the equipment allows you to install the unit in any convenient corner of the room. Accumulative electrical elements produce rapid heating of the liquid. The budget version is divided into classifications by displacement - 30, 50, 65 and 80. You can buy a unit at an average cost - from 8,000 to 14,000 rubles.

First power on

In order for the device to properly perform the functions for its intended purpose, you need to follow the selection recommendations, install the equipment and make the first switch-on, taking into account all the rules. Most Ariston water heaters are characterized by the following step by step instructions launch:

  1. First of all, the cold water supply valve opens. It is very important not to confuse the element with the safety lever.
  2. At the same time, open all mixers that receive a hot stream of liquid. The faucets will produce loud sounds and the pressure will be intermittent.
  3. Wait until the tank is completely filled when a steady stream of water comes out of the faucet.
  4. Turn on the power, set the temperature to medium.

It will be possible to increase the degree of heating after the first start-up of the equipment.

Very important in a water heater accumulative Ariston 50, 60 or 100, fix the lever in the required position, which is responsible for supplying hot pressure. If you ignore the situation, the heated liquid can enter the common riser of the house.

Repair work

Like any other technique, an electric storage water heater of 50 liters is flat or rounded, has vulnerable elements. In this case it is:

  • Thermoregulatory system;
  • Heat transfer sensors;
  • Switches;
  • heating elements.

Valves or gaskets are often the first to fail. The integrity of the boiler is violated in rare cases. The reason for this can be corrosion formations and improper operation. In case of serious damage, you must contact the service department.

Repair of Ariston 50 at home provides only preventive processes associated with the timely cleaning of heating elements. Experts recommend cleaning parts at least twice a year.

First signs of breakdown

  1. During operation, the device emits a hiss.
  2. The average amount of time spent on heating water has increased significantly.

Before proceeding with repair work, it is necessary to carry out preliminary preparation of the device. To begin with, the power supply is turned off, the liquid is drained from the system, the water supply is shut off.

The most optimal option for descaling is considered lemon acid previously diluted in water. The liquid is poured into the tank for a day, after which the mixture is poured out and the container is washed from the remnants of plaque with clean water.

The magnesium anode helps to solve the scale problem, in which the potential limit is lower than that of the tank coating and the heating element itself. If to speak plain language, the process of rust formation begins precisely from the anode, and only then it “spreads” to the heating element and inner surface tank. With regular replacement of the anode (on average 1 time in 8-12 months), the heating element will not need to be cleaned, and the equipment itself will work properly.

All modern water heating equipment is already equipped with removable magnesium anodes. The user is only required to timely replace with original consumables.

If you need to replace parts yourself, you should purchase only original items. Spare parts can be ordered from a specialist dealer or from direct suppliers.

Disadvantages of Ariston 50 l, 60, 100

  • Requires regular preventive maintenance to clean the heating element from scale. If you clean the heating element less often, this will lead to a quick breakdown of the device.
  • Uneconomical consumption of electricity.
  • Expensive repairs and spare parts.

Typical boiler diagram Ariston 50


Electrical accessories storage water heater Ariston.

Electric storage water heater Ariston consists of:

  • outer case;
  • bracket;
  • internal tank;
  • hot water outlet;
  • magnesium anode;
  • cold water inlet;
  • heat insulator;
  • thermostat sleeves;
  • heating element (TEN);
  • flange;
  • thermostat;
  • power cable;
  • regulator knobs.

To connect the Ariston boiler correctly, you must follow the manufacturer's instructions.

First, the water heater is mounted on a wall or a supporting surface and a drain is provided from water pipe(cold water). It is most advantageous 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. In the absence of a collector, the nearest segment of the water pipe is cut, a standard tee is installed at the cut site.

The installation method of the tee depends on the material from which the pipes are made. On plastic fasteners is carried out using a special soldering iron, on metal - threaded.

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


Scheme for connecting an electric storage water heater Ariston.

To connect the water heater to the water supply, you should:

  1. Pay attention to the hot and cold water pipes - it is important not to confuse them. Installed on cold check valve, it can be included in the standard package. Hot water is connected via a pipe. First, a cold water pipe is mounted, then a hot one.
  2. A special tape is wound on the threads as a sealant and sealant, this is recommended by the manufacturer.
  3. 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 emergency possible under abnormal pressure or heat. A shut-off valve and an adapter are installed under the tee at a short distance. The next step is connecting to the water supply.
  4. Connection to hot water is also made by installing a shut-off valve.
  5. In the case of connecting different metals, adapters should be used.

The connection to the mains is carried out as follows:

  1. V switchboard a separate machine (RCD) is installed, it is connected to a 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 gate is punched in the wall).
  2. 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 the machine. The "switch" is closed in a compact cabinet with a removable panel.
  3. A separate RCD machine and a “switch” are connected by a wire.
  4. A three-wire wire is connected to the heating element, for this the bottom panel is removed from the water heater.
  5. Then the output of the machine is connected to the boiler.
  6. The next step is to wire the ground, phase and zero lines to the appropriate connectors.

Scheme of connecting the Ariston water heater to the mains.

Before turning on the device, you must make sure there are no leaks and correct position flange (strictly in the middle). Then fill the tank cold water and open the hot water faucet to release the air. After the air is released, the valve closes and a trial run is carried out.

How to identify a malfunction

For repair work the user needs to notice a malfunction in the operation of the water heater in time. Ariston boilers are often equipped with an electronic display on which messages appear in case of equipment failures.

Direct signs of a malfunction can be:

  • operation of the machine at the moment the boiler is turned on - this indicates a malfunction of the heating element;
  • heating water above the maximum allowable temperature - this indicates a failure of the thermostat;
  • heating water below the required indicators - this may indicate contamination of the heating element, the appearance of scale;
  • drips at the bottom of the tank and on its walls;
  • breakdown of the information board, which most often does not cause significant failures in the overall functionality of the device, but can reduce comfort during its use.
