Electrolux appliances have good quality... The service life of gas water heaters is ten to fifteen years, but subject to their regular maintenance and respect for the equipment.

Device and principle of operation

All gas water heaters have a similar design and system of functioning. The Electrolux geyser on the body has toggle knobs that regulate the heating power and water supply. Each device has its own throughput, some columns can heat up to sixteen liters of liquid per minute. Thanks to the optimal chimney connection, the technology of this manufacturer is characterized by versatility. Geysers can work together with an exhaust system.

Equipment items:

control pads and adjustment buttons (many Electrolux models are equipped with a display on which you can see water temperature and all other indicators);
solenoid valve;
copper heat exchanger;
holes for water and gas inlet;
a hole for the outlet of the heated liquid;

fasteners.

Due to the quality of parts and design, this equipment is absolutely adapted for use in our country. If the water supply pressure or gas pressure changes in the line, the device will function at the same level. Two pipes are mounted in the casing of the gas columns, the first for the flow of gas, the second for water. At the bottom of the equipment there are burners, which have a basic view and an ignition one. Depending on the selected model, the device has electric ignition, piezo ignition or manual ignition.

There is nothing complicated in the principle of the operation of a water heater. The heat exchanger passes cold water, the liquid is heated in it thanks to the burners located below. The oxygen required for combustion penetrates into the apparatus through ventilation system... The exhaust gas exits through the chimney. The incoming heated water enters the sink through a pipe.

Popular models

Electrolux has established itself from the very better side... This is evidenced by the reviews of buyers and specialists. Electrolux GWH 265 ERN Nano Plus is a heater in demand today, which is characterized by a power of 20 kW, as well as a capacity of ten liters of water per minute.

User manual

Everyone who has purchased water heating equipment must use it correctly, without violating safety rules. Basic rules of use:

it is prohibited to use a gas water heater at a time when there is no draft in the chimney;
broken equipment cannot be used;
the room in which the gas water heater is installed should not have leaks - if such a situation arises, it is necessary to urgently ventilate the room and call the gas service.

Every gas water heater owner should remember that gas leaks can be very dangerous. The operating instructions supplied with the kit must be fully followed. There are situations when the column does not work when the water is turned on or heats up the water weakly. In this case, it will be necessary to check its heating elements. It is important to know that any heating element has an expiration date, so the user should have batteries in stock to change at the right time.

Everyone who has just purchased Electrolux equipment is interested in the question of how to turn on the column and light it up. The first step is to turn on the taps for water and gas supply. This is done in three ways.

Manually.
Piezo ignition, which is quite simple to use. To turn on the device, it is enough to press a button, as a result of which the filter is ignited.
Automatically. It is a pleasure to use equipment with such a system, because practically nothing needs to be done, everything is done by the technician.

To properly set up the operation of the gas water heater, you do not have to use a lot of knowledge and skills. There is a scale and two handles on the panel of the device. On the first scale there are divisions, and using the handle, the required fluid supply is set. At the same time, the second scale and the knob are intended for setting and adjusting the gas supply. It is necessary to adjust the functioning of the gas column immediately after installing the device. Thus, the operation of the device and the consumption of water and gas are optimized.

It is necessary to adjust the water consumption, guided by the nominal pressure, which is indicated in the technical passport of the product. In order to set the performance value, the valve is opened with hot water, the handle is installed on the scale, and the valve closes.

To prepare the work of the gas valve, first of all, you need to install the equipment at the minimum mark. Then you need to connect the column to the network or insert batteries. Then the tap on the gas pipe opens. After the hot water tap is opened, the device will automatically turn on and the liquid will be heated. Many Electrolux models provide economy mode, the setting of which is described in the instructions for the equipment.

Malfunctions and their elimination

Gas water heaters are devices that are used continuously, so even the most expensive model can have breakdowns. The main problems that the user encounters when operating this type of equipment are the following.

The column does not light up

There are several reasons that caused this situation. First of all, you need to check the combustion of the igniter, if it is faulty, then it is worth calling a master who will clean the element. In columns with electronic ignition, it is recommended to check the solenoid valve, it often cuts off the gas supply. The solution may be to simply replace the battery. The gas water heater does not turn on if there is no draft in the ventilation well. Removing the blockage will help to return it. The deterioration of the water membrane can be considered as the reason for the lack of ignition. In case of deformation, spare parts should be replaced. Also, we must not forget about the possible clogging of the filter, which can be easily replaced by yourself.

2016-10-14 Evgeny Fomenko

To start Electrolux, you need water to enter the system. To do this, first of all, open the tap and drain the water a little. It is important to inspect all pipe connections for leaks.

After that, the gas valve opens. In this case, the characteristic sound of gas entering the system will be heard. After that, you can turn on the tap, from which the heated water should flow. The tap opens as soon as possible. If the water pressure is strong enough, the crackling of a piezo ignition spark in the column and the sound of gas ignition will be heard. In order for the water heater to work, the pressure must be in the range from 0.15 to 10 atmospheres. After a short time, the water will heat up. If the column is new, the water may have a slight machine oil odor, which will wash off over time.

When using the Electrolux gas water heater, it is not recommended to dilute heated water with cold water. When turned on cold water resistance is created for hot, the flow decreases, the column can go out. It is necessary to set a comfortable temperature level in advance and adjust it as needed on the column itself. To make the water a little hotter, you can reduce the flow of water. But at the same time, if the pressure is too low, the flame will automatically go out.

Regular use

Gas water heaters from left to right Electrolux GWH 275, 285, 350

To extend the service life of the Electrolux gas water heater, it is important to adhere to several recommendations when using hot water.

The most expensive part of a column is the thermostat. In Electrolux 275, 285 and 350 water heaters, the heat exchanger is made of copper. It is constantly in contact with hot water, therefore scale forms on it. It is not recommended to set the maximum water temperature. Optimum temperature for work 45-50 degrees.

Using the tap to the right of the display, you need to limit the water pressure in the column. This will avoid sudden pressure drops in the structure.

If you know that the hardness of your water is high, it is advisable to install an additional purification system. Calcium and magnesium salts, which are contained in such water, quickly build up scale in the thermostat. Installing a filter at the inlet of the device will extend the life of the device.

Even if all the recommendations are followed, scale will still appear. According to the instructions, you need to clean the Electrolux column once a year. It should only be carried out by specialists. Workers clean the thermostat from scale and the burner from carbon deposits.

Safety engineering

Any gas equipment requires compliance with safety regulations. Before starting work, it is important to carefully read the official instructions.

Here are the main excerpts from these instructions:

Columns Electrolux 275, 285 and 350 are equipped with gas attenuation control and water temperature limitation.
First of all, with prolonged use of the gas water heater, from time to time you should check the draft of the chimney. To do this, a match is brought to it and the presence of an air flow is determined by the movement of the flame. Gas workers have special instruments for measuring the thrust force. It is recommended to check it every three months.
For safety reasons, the window must be open during the operation of the column. A two-centimeter gap is made at the bottom of the door of the room.
Install water heaters in a place protected from the access of small children. It is forbidden to independently make changes to the structure. Some parts of the water heater may be hot and burns.
If you smell gas in the room, you should urgently put out the fire, disconnect the column, turn off all electrical appliances and call emergency service... Can't obstruct access to gas pipes and equipment, as well as tying clotheslines to them.
If the column is installed in a room without heating, in cold weather, when it is not used, you need to remove water from it.

Advantages

Gas water heaters Electrolux 275, 285 and 350 have a number of advantages over other models of water heaters:

Low price, simple construction and wherein high reliability... The lack of a lot of fashionable electronics reduces the likelihood of device breakdown.

Among the disadvantages can be noted too high sensitivity of the throttle control knob. And a feature of all gas water heaters is the need high pressure water, without which it simply does not start.

If you correctly install the Electrolux gas water heater and observe safety precautions when using it, then it will regularly supply you with hot water and will last a long time. Over time, users get used to the peculiarities of work gas water heaters and consider them the best choice.

Interruptions in hot water supply deprive us of the usual comfort. To prevent this from happening, you can use the additional options for obtaining hot water. One of the devices dedicated to this purpose is a gas water heater. If you learn to use it correctly, the technique will be easy to operate. And one of the pressing questions: how to turn on the gas water heater?

One of the most common myths that scares off potential buyers is that this technique is dangerous to use. However, this bias is valid when using old-style models. Today, the units are improved and safe, many of them (for example, proposals from Bosch) are equipped with automatic protection , in which in an emergency, the flow of fuel is cut off.

To know the terms of use, you should draw up represent it internal organization. Any firm's models include all of the following:

gas equipment unit;
water connection unit;
exhaust connection system;
other mechanisms;
electrical appliances.

The body itself resembles outward appearance cabinet that connects to the water supply and gas supply. Heating elements located in its lower part and represented by the main burner and igniter.

How to use a gas water heater correctly? The device operates according to the following principle:

cold water under pressure enters the heat exchanger - this will automatically open the fuel valve;
the ignition device ignites;
gas will go to the main burner, where it is ignited from the igniter;
heat will heat the water;
combustion products are removed through the chimney and exhaust system.

How to light up the apparatus

Before starting work, you must open the gas and water taps. There are three ways to light a gas water heater.

Manually

The manual method was used in old-style models... In this case, you have to light it with matches. Here it was necessary to perform a number of such preliminary manipulations:

open the water supply connected to the device;
open the main valve for the fuel flow to the igniter;
light the wick with matches;
turn on the valve (main) for gas supply.

The downside is that you have to turn off the wick manually. It is required to master the above practical skills and keep children away from the device.

With piezo ignition

We can say that this is a semiautomatic column. How to use this type of gas water heater? It will be enough push the button to ignite the wick in the combustion chamber. With the help of mechanical force, a spark is transformed - it is enough for the ignition filter to ignite. With this method, a number of mandatory requirements must also be met:

in order to ignite the main burner, it will be necessary to turn on the main regulator in the fuel supply;
the pilot filter will remain lit when the regulator is returned to the main position and the water is turned off.

There is a drawback in such designs - excessive fuel consumption. Vivid examples of such speakers are the Bosch WR 10-2 P miniMAXX-2, Nevalux 5111, Junkers WR 10-2 PВ models and other options.

Automatically

Opportunity automatic switching on provide completely advanced modifications that are easy and safe to use even for beginners. Hydropower system offered by most modern manufacturers (Bosch, its direct competitor Electrolux and many others). The process of starting a job is simplified to the limit.

For example, in the Bosch Therm 6000 O, the water pressure drives the turbine. It launches inside the device automatic system fuse of both the wick and the main burner.
Have manufacturer Bosch there are Therm 2000 O and Therm 4000 O lines, which carry out electric ignition from batteries (it will be necessary to monitor their service life).
Have speakers Bosch the AM1E series already has a digital control panel that will show everything at a glance possible mistakes inclusion.

A fully automated process has one drawback: many homes have low water supply pressure, and this may not be enough to normal work turbines. In addition, such devices are significantly more expensive than their less perfect counterparts.

Mandatory precautions

Any purchased equipment comes with instructions for correct operation gas water heater. The principle of operation of most of them is identical to that indicated above, but here the mandatory adherence to safety precautions should be highlighted.

It is required to conduct preventive cleaning gas water heater in order to avoid disruption of the efficiency of its work (how to do this, you can read in the document that goes to the gas water heater - instructions).
It is important to check the condition of the chimney ducts - this will help to avoid clogging.
If the device fails, you should immediately contact gas service... Unauthorized attempts to fix the problem are prohibited.

In more detail, the inclusion of the unit is shown in the video:

It is enough to understand once how to light the device to provide comfortable and instant heating. running water... And then you can simply enjoy the operation of this convenient heater.
