How to choose a reliable geyser. Rating of the best geyser models

Modern man accustomed to comfort. That is why the majority of Russian citizens, when purchasing heating equipment, give preference to devices controlled by electronics.

Automatic is a flow-through heating device, the ignition, control and protection from emergency situations is carried out automatically, i.e. without human intervention.

But you have to pay for comfort, so the price of an automatic gas water heater is 30-50% higher than the cost of manually operated devices and 15-25% higher than their semi-automatic competitors.

To find out where to buy a gas water heater of the brand you are interested in, technical specifications and real cost selected model, contact the online product catalog Tkat.ru.

Design features

What does the consumer mean when choosing automatic device to create hot water supply in an apartment or private house: when you turn the tap handle, the unit turns on automatically and supplies hot water at the set temperature to the tap.

When the tap is closed, the unit turns off automatically. This is exactly how an automatic gas water heater should work, judging by the reviews.

What does the manufacturer mean by automatic device:

1. Equipping the unit with electric ignition. When the tap is opened and sufficient pressure is reached in the circuit, the sensor gives a command to the control system to create a spark in the fuel combustion chamber. Almost simultaneously with the spark, gas is supplied to the burner. After closing the hot water tap, the pressure in the circuit drops and the electronics shut off the fuel supply to the main burner. There is also more expensive equipment - a built-in hydraulic turbine. It does not require mains power or batteries to operate: it itself produces voltage to create a spark, with a water pressure in the circuit of 0.35 - 0.45 atmospheres.

2. Equipping the heating device with a modulating burner. Each automatic gas water heater has a water temperature programming function. The modulating burner can independently adjust to the fluid pressure in the heat exchanger. For example, for a comfortable bath, the user needs a water temperature of 50°C. When the pressure in the water supply or its temperature fluctuates, the burner independently regulates the flame size to achieve the desired temperature.

In addition, manufacturers of such units equip devices with protection that operates automatically. All models, regardless of the manufacturer, turn off the fuel supply when the water pressure in the heat exchanger drops, stop the operation of the device when the power supply is turned off, stop the gas supply when the draft in the chimney decreases or the fan is turned off in turbocharged units.

You can find out how much an automatic gas water heater costs, the required performance and the required brand on the pages of the electronic product catalog Tkat.ru.

Leading European and domestic companies produce automatic and semi-automatic instantaneous gas boilers. Modern speakers bear little resemblance to those used in the 60s of the last century. When immediately after washing you had to run and turn off the boiler. Modern semi-automatic dispensers differ from fully automatic models only in the ignition principle used.

When choosing a suitable water heater, you need to consider the following aspects:

• price;
• ease of use;
• principle of operation;
• pros and cons of each model.

Column machine - what is it

All built-in functions: flame modulation, automatic adjustment temperatures and others are present regardless of the type of ignition used. For this reason, to say that a semi-automatic is definitely worse would be a hasty and erroneous opinion.

How automatic speakers work

• the device has only one gas burner;
• when the hot water tap is opened, water flows into the reducer connected to the gas valve and the electric ignition unit;
• the created pressure sets the rod in motion, which sends a signal to supply gas and generate a spark that ignites the gas;
• after closing the DHW tap, boilers with automatic switching on and switching off completely extinguishes.

In the latest generation of water heaters, ignition is carried out using a hydraulic turbine. Automatic ignition uses electricity generated from the movement of water. Otherwise, the operation of the speaker is identical to that running on batteries.

On outside The casing houses a mechanical or touch control unit: two levers that change the pressure of gas and water supplied to the burner and heat exchanger. The settings are permanent and do not change during the water heating process. When the pressure changes, the heating intensity of the liquid changes.

The gas water heater with automatic water temperature control has a modulating burner. The consumer sets the required DHW heating intensity, which radically changes the purpose of the control automation. Sensors monitor any changes and, with less or more water pressure, automatically adjust the operation of the burner so that the DHW output is at the set temperature. Typically, such speakers have an electronic control board.

Pros and cons of electronic speakers

• Economical - in the process of heating water, the columns burn the same amount of gas as semi-automatic models. Costs are lower due to the fact that there is no constantly burning pilot wick.
• Ease of use- automatic gas instantaneous boilers turn on independently when the DHW tap is opened and turn off immediately after it is closed. On the external front panel there is an LED display connected to temperature sensors and displaying the temperature.
  Setting up an automatic gas water heater is not difficult; just turn the knobs to change the water pressure or gas pressure, focusing on the digital heating value. Models with electronically controlled equipped with a touch panel, which adds even more comfort.

The second drawback is also associated with the listed nodes. As statistics show, water heater breakdowns most often occur due to malfunctions in the ignition unit and regulator. The causes of malfunctions range from the most banal: the batteries are dead (you will have to change every few months) to the complex: the spark producing unit has failed.

Popular models of automatic speakers

• Hyundai H-GW1-AMW-UI305 / H-GW1-AMBL-UI306- a simple classic model with electric ignition and basic functions. The heating temperature is changed using rotary mechanical knobs. It has a beautiful and stylish appearance.
• Ariston Gi7S 11L FFI - the dispenser is equipped with touch controls and can operate on natural and liquefied gas. The body is made of of stainless steel. There is a turbocharged modulating burner, a closed combustion chamber.
• Electrolux GWH 10 High Performance- ignition from the mains. Mechanical control unit. A screen is installed on the external panel to display the heating temperature.
• Ariston NEXT EVO SFT 11 NG EXP- geyser with flame modulation. Operates from a household power supply of 220 V. Has a closed combustion chamber and a system that prevents freezing. Control via touch panel.
• Edison P 24 MD - model with modulation heating control. There is a convenient temperature memory function. The column will automatically heat the water to the parameters used the last time it was turned on. There is a self-diagnosis system and multi-stage protection against overheating and gas leaks.
• BOSCH WTD 18 AME - a column with a closed combustion chamber and forced removal of combustion products. Combustion modulation is carried out within 60-100% of the rated power.

Semi-automatic dispenser - what is it?

The main difference is that when starting the water heater, human intervention is required. After igniting the wick, the column works like an automatic machine. The igniter is ignited with matches (in older models) or a piezoelectric element.

How does a semi-automatic dispenser work?

• Turning on - before using, you must light the wick. The pilot light will burn continuously and ignite the main burner. To turn on the semi-automatic dispenser you need to complete the following steps:
  1. put gas on the igniter;
  2. wait 10-15 seconds;
  3. light the wick using the piezo ignition button;
  4. Without pressing the gas supply button, wait another 20 seconds;
  5. release the key, the wick should continue to burn.
  The automation of semi-automatic water heaters works like... When heated, static electricity is generated, which clamps the valve. Once the required temperature is reached, the wick will continue to burn until the gas supply is manually turned off.
• After igniting the wick, you can light a semi-automatic gas water heater in the same way as an automatic one. Just open the hot water tap and the main burner will start working. After the DHW is closed, the fire goes out.

The operating principle of semi-automatic geysers and their internal organization in many ways identical to automatic water heaters. The only difference is that ignition is carried out by means of a constantly lit wick.

Advantages and disadvantages of semi-automatic

• simplicity of the device;
• lack of expensive electronics;
• low cost compared to automatic speakers.

• Using gas semi-automatic instantaneous water heaters is less convenient than their automatic counterparts. Every day in the morning you will have to light the wick, which is left to burn constantly.
• The igniter consumes about 0.8 m³ of gas per day.

The best models of semi-automatic speakers

• Vaillant AtmoMAG exclusive 14-0 RXZ- a powerful column for simultaneous provision of two water collection points. Flow rate 14 l/min. On the outer front side there is a mechanical control unit and a piezo ignition button.
• Teplox GPVS-10 - flow column, powered by a wick. The water heating temperature is displayed on the display. There is a “summer-winter” mode. Adjustment is carried out using rotating knobs that change the pressure of water and gas.
• Mora Vega 10 is a simple and reliable speaker for household needs. Suitable for providing domestic hot water for one point of consumption. Capacity 10l/min.

• BOSCH WR 15-2P is a semi-automatic dispenser with flame modulation function. Atmospheric combustion chamber. Capacity 15 l/min. Suitable for providing multiple water points.
• Baxi SIG-2 11p is another model with automatic maintenance of the set temperature through flame modulation. The column automatically maintains the set water heating temperature. Changes combustion power when pressure drops in the supply pipeline. The display shows the water heating temperature.

Conclusion - automatic or semi-automatic?

• Cost - the price of a semi-automatic dispenser is almost 50% cheaper. If you don’t have extra funds and need a budget model of a gas boiler, then there will be no better option. Automatic gas water heater good quality costs starting from 25-30 thousand rubles.
• Cost-effective - flame modulation in the column is available both in the automatic column and in the semi-automatic analogue. A constantly burning wick spends about 0.8 m³ per day, which is quite wasteful; additional costs per month will be 24 m³.
• Ease of use- an automatic machine differs from a semi-automatic machine in the principle of ignition. The constant need for a wick somewhat reduces the comfort of using models with piezoelectric elements.
• Easy to use- even with the help of the operating instructions supplied by the manufacturer, learning to use a semi-automatic dispenser is not easy. Automatic water heaters operate independently of humans. They turn on and off when the DHW tap is opened/closed.
• Reliability - the undisputed leader is occupied by semi-automatic boilers, in which there is simply nothing to break. Only some gaskets are subject to wear and can be easily replaced if you have technical skills yourself. Automatic boilers have a sensitive ignition unit and automation, which requires repair on average every 4-5 years.

During the construction of apartments, hot water is currently supplied centrally, but for residents of Khrushchev-era apartment buildings and individual houses, the question of how to choose a gas water heater is still on the agenda. Of course, modern speakers are not those harsh units with manual control and ignition with matches that were equipped with apartments in the middle of the last century. They staged “New Year’s fireworks” when forgetful owners tried to dilute too hot water. However, current devices have quite enough individual nuances for buyers to approach this issue with due responsibility.

Key parameters to pay attention to

If you are already thinking about which geyser is best to buy, pay attention to the following parameters.

The power of the unit comes in three kW ranges: 17-19; 22-24, 28-31. The lowest power of the device is enough to supply hot water one point in the house, such as a bathroom or kitchen. If it is necessary to serve two or more, then at least 15-20 liters per minute should pass through the column at a heating temperature of up to 35-40 degrees, and here it is better to choose at least medium power.

The water pressure in the apartment also plays an important role, because even with powerful unit it may not be enough to heat the water as required. Spending money on an expensive device with high power in this case it makes no sense.

The type of ignition that a modern column has is of two types:

• automatic - the device starts automatically when the water is turned on, while a spark is knocked out using a turbine or battery;
• semi-automatic - the gas water heater has a piezo ignition, a spark is knocked out when you press a special button.

Automatic speakers are the most expensive in price, due to their increased comfort and the ability to save gas, because they do not have a pilot igniter and the wick only lights up when the water is turned on. When you directly turn the handle of a hot water tap, the electronics immediately ignite the igniter or supply a spark to the main burner. After the tap is closed, a special valve blocks the access of gas to the column from the pipe. Such devices can be powered by electricity or batteries.

In dispensers with piezo ignition, the pilot flame must be lit, otherwise the dispenser will not work when the water is turned on. This increases gas consumption if the wick is constantly on in standby mode.

The type of burner also plays an important role and comes in two types:

• with constant power - this option is inconvenient because it requires manual adjustment, because the water pressure in the system often changes, and the heating temperature changes accordingly, which has to be constantly adjusted manually;
• with modulating power - it is better to choose this type of device, because it adapts to the water pressure in the system and maintains the temperature that was initially set.

The gas pressure in the system is something that you definitely need to pay attention to the seller in the store. In our country, the gas pressure in the network is less than in European countries: 13 mbar versus 20, so when buying a gas water heater from a European manufacturer, be sure to ask which gas pressure scale is applicable for of this device and whether a gas reducer is installed in it to maintain constant pressure. If the column is not adapted to Russian utility standards, then the device will not be able to gain the required power.

Regarding the removal of combustion products, columns are divided into:

• chimney - it is best to choose this one best option when the corrugated hose of the column is discharged into the chimney existing in the house;
• turbocharged ones are a rather risky system, when the outlet under the column is made directly into the wall, which is fraught with freezing of the outlet paths in extreme cold and you need to constantly drain the remaining water so as not to rupture the heat exchanger.

Safety is the most important parameter

A gas water heater is a highly dangerous device; various malfunctions often occur in the gas and water supply system. Therefore, the units are equipped with various protective sensors and relays. When the question arises of how to choose a gas water heater, pay attention to how many such devices are available in the models you like. The most basic of these sensors are the following:

• ionization sensor - instantly shuts off the gas supply when the wick goes out;
• thermocouple (combustion sensor) - serves as a safety device in case of failure of the ionization sensor, performing its functions due to failure;
• overheating sensor - prevents the temperature of the heated water from exceeding, protecting the heat exchanger from rupture, and also neutralizes the possibility of scale formation;
• flow sensor - automatically turns on the gas water heater the moment the hot water tap opens and turns it off when closed;
• draft sensor - blocks the activation of the column in the absence of draft in the chimney, preventing the formation carbon monoxide in room;
• temperature sensor - adjusts the flame power;
• safety relief valve - protects the heat exchanger from damage by blocking the column when high blood pressure water in the system;
• low water pressure sensor - does not start the column if the water pressure is not enough for its safe use.

The best manufacturers of geysers

To ensure that your purchase is successful, before choosing a device, it is better to familiarize yourself in advance with the list of the most popular companies producing geysers.

• Ariston – excellent Italian quality at the best price. The devices are characterized by high operating efficiency and are equipped with a complex of various functions. Units and parts are made of composite material, which guarantees long service life and corrosion resistance;
• Vaillant is a quality German brand on the market gas equipment. The devices are distinguished by high productivity and unpretentiousness in operation. Equipped with reliable copper heat exchanger, create a minimum of problems, have a long service life. These speakers are distinguished by a beautiful silver surface, suitable for kitchen appliances.
• Junkers is a series of speakers produced in Germany by the famous company Bosch. Consistently popular on the Russian market for many years, they embody all the best qualities of this famous brand and satisfy the requirements of the most demanding customers;
• Electrolux - burners in columns of this brand are equipped with a small number of nozzles, so the operation of the device is accompanied by much less noise than in models from other manufacturers. This point may be important for some consumers and it is better for them to choose just such a column. For process safety, an Intelligent control system is used that monitors the correct functioning of all sensors and systems.

Lack of hot water supply is not a problem - everything is solved by installation good water heater. Gas options have proven themselves to be excellent. However, it is very easy to get confused in the modern assortment, so even before going to the store, you need to figure out in advance which geyser is better and find out expert reviews about specific products.

There are many manufacturers of such units - among them there are many worthy and reliable options. It is important to focus on the following indicators:

• power of equipment;
• ignition type;
• type of burner;
• safety.

The power characteristic affects its overall performance. In fact, it determines the amount of water that the device can handle in a certain period of time. Power can be low (from 17 to 19 kW), medium (22-24 kW), high (from 28 to 31 kW). When choosing power, you need to focus on the expected number of water intake points in your home. If there are several of them (and their simultaneous operation is assumed), then it is better to choose a unit with medium and high power.

The type of ignition is also relevant. Previously, a lighter and matches were used for this. Modern models suggest semi-automatic or completely improved automatic system . In machines, the spark is provided by turbines or a battery, and to start, you just need to open the hot water tap. There is also piezo ignition (semi-automatic option), which involves pressing the button intended for this. The bad thing here is that this method increases fuel consumption (the wick will burn even after ignition is completed).

It is worth paying attention to the type of burner. You should not take one that has a constant power - you will have to regulate it, adjusting it to the water pressure in the system. The best idea of ​​the developers is if the power is modulating. Such an element is capable of independently adjusting to the flow, and then the temperature will be relevant.

Finally, when it comes to operational reliability, you should pay attention to safety. Modern models of geysers are equipped with three levels of protection, which manifests itself in various incidents - accidental cessation of flame, sudden appearance of reverse draft. There are also special hydraulic valves to help avoid overheating.

It is also important how the combustion products will be removed - this can be done using the turbocharged method and using a chimney. In the first case, everything will go straight into the street, and in the second, into the chimney system.

Analysis of popular geysers

Experts in the field of such equipment have already compiled a rating of geysers. The opinion of experts formed the basis of the review, which presents the top 5 best brands who specialize in their production.

1 place for Bosch WR 10-2P

The undoubted leader of the review is the Bosch WR 10-2P model. It attracted ordinary users stylish design and compact sizes. The unit will fit harmoniously even into small room. Experts unanimously recognize it mostreliable: Automatic ignition system is used. The device itself is activated when a hot water tap is opened. The heating temperature limitation has also been thought out. Ignition is carried out using a piezo - no batteries are needed.

Column Bosch WR 10-2P

With this technique you don’t have to worry about the pressure – it will work even if the pressure is not stable. By the way, you can regulate the flame and temperature of the liquid using special regulators.

However, such “perfection” also has minor drawbacks.

1. The performance of the model is approximately 10 liters per minute. This is considered not the best indicator.
2. The quality of the water affects its performance.
3. To clean the device, it must be completely disassembled.
4. Service is expensive, and not every city has an authorized Bosch representative. In addition, you will immediately have to prepare for high cost of original spare parts.

2nd place for Ariston Fast Evo 11C

Ariston Fast Evo 11C is on par with its competitor from Bosch: it is also capable of operating even at a nominal water pressure of 0.1 bar. There is also a well-thought-out safety system: flame control, a thermostat that protects from overheating, and a draft sensor. You can set the maximum temperature (limit 65°C).

One of the main advantages is work from the network, What better option with batteries that can run out at any time. A heating power of 19 kW will provide a productivity of 11 liters per minute of working time.

Column Ariston Fast Evo 11C

There is also a minus that did not allow this device to take a leading place in the top - the temperature on its digital display is displayed incorrectly.

The best inexpensive offer in 3rd place from Neva Lux 5514

This, without a doubt, can be called the Neva Lux 5514 option - this option can easily compete in build quality with expensive foreign offers. Of course, the functionality here is not as chic as that of popular brands, but overall the model is impressive:

Users are delighted with another point - the initial settings last for several years. Everything will work efficiently and will not go wrong.

Column Neva Lux 5514

The following disadvantages prevent you from rising to the top:

• noticeable noise during operation;
• replacing batteries;
• expensive in case of heat exchanger.

Advantages and disadvantages of Mora Vega 10 in 4th place

The Czech manufacturer from Mora Top Vega 10 has a capacity of less than 10 liters, but it won fourth place in the top best geysers thanks to another number of advantages:

• European build quality (manufacturers promise that the design does not contain a single part from the Middle Kingdom);
• copper heat exchanger (increases efficiency to 92.5%);
• scale-free technology in pipes;
• a full range of safety systems (does not start without turning on the water, protection against overheating, against the appearance of reverse draft, the presence of fuses for the operation of burners).

Column Mora Vega 10

Unlike competitors, Mora Top has a more noticeable weight - at least 2.5 kg. However, there is also a drawback: with low water pressure, the device may simply not turn on (the manufacturer sets a calculation of at least 0.2 bar).

5th place for Zanussi GWH 10 Fonte

The excellent Zanussi GWH 10 Fonte geyser will quickly and efficiently heat water in a cottage or apartment. The unit will look good in any interior, it makes little noise and uses resources economically. Productivity can be adjusted from 5 to 10 l/minute. The equipment will work even with low water pressure (literally from 0.15 bar). The disadvantage of the device is that it will require periodic replacement of batteries.

Speaker Zanussi GWH 10 Fonte

All presented samples are the best geysers, despite the allocated places. The choice will be determined by the objective and subjective indicators that the buyer expects from his purchase.

Others not included in the list, but no less worthy representatives include Vaillant, Electrolux, Termaxi, Beretta, Vector.

Having decided which geyser is better, the buyer purchases new equipment. It doesn’t matter which model was chosen from the proposed top - in order for it to work better, you need to listen to useful advice.

1. Installation and connection should be trusted qualified specialists, because the settings directly affect the quality of its work.
2. The output temperature should not exceed 60 degrees (for some models 40 will be enough). This is necessary to prevent the formation of scale that will collect on the membrane.
3. If it is known in advance about hard water, then it is better to equip the unit in advance with a system that will prevent salt deposition.
4. During operation of the device, it is prohibited to adjust the temperature by opening the tap from cold water. This will cause steam and excess pressure to build up in the system due to excess hot water. This is also bad because water may begin to leak from the heat exchanger.
5. It is important to regularly clean the igniter and heat exchanger. Here it is necessary to clear blockages that appear from combustion products.
6. It is also important to monitor the water pressure - if it is insufficient, you will have to additionally install a special pump.

Such prevention will help the device to perform its “duties” well, and users – all year round enjoy hot water.
