Which geyser to choose for your home. Which geyser is better? Reviews from experts and owners

It is no secret that not only owners of private houses, but also owners of apartments in high-rise buildings have recently increasingly installed their own independent heating and hot water supply systems. About - in a separate publication, and this article will be devoted to questions of how to choose a gas water heater so as not to have problems providing your household with hot water.

Probably everyone knows common Since ancient times, the expression: “my home is my fortress.” You can, of course, put a variety of meanings into it. But if you look from an everyday point of view, from the position of a caring and economical owner, then this can be perceived as a desire for the greatest possible autonomy, for independence from public utilities with their unpredictable quirks in the form of changes in the conditions for the provision of services, tariff increases, supply failures, preventive maintenance, accidents and the like.

But even before the speech will do about the problems, in fact, of choosing these devices, you need to, at least briefly, familiarize yourself with their basic structure. This is necessary, first of all, in order to try to dispel a number of fairly common prejudices that were formed in the collective consciousness regarding speakers quite a long time ago are firmly entrenched there and are very difficult to “neutralize.”

The design of a geyser and its advantages

In order not to make mistakes when choosing such a heating device, it is necessary to at least approximately understand its structure. Although The range of modern geysers is quite large; their operation uses the same principles of both internal structure and functionality.

The diagram shows the approximate structure of a typical modern flow-through gas heater. Of course, specific models from different manufacturers may have their own characteristics, but only in matters of layout or ease of use.

1 – fume hood, closed with metal walls, a volume from which gas combustion products are removed in one way or another. It can be completely sealed or connected to the atmosphere (in conventional, chimney or chimneyless columns).

2 – copper heat exchanger. A pipe system with a “jacket” that receives the direct impact of the flame of gas burners. This is where the heating of running water takes place.

3 – ignition sensor. Provides a control signal to open the common gas solenoid valve only if the ignition wick is operating.

4 – ignition wick. There may be different principles of operation - this will be discussed below.

5 - gas burner, more precisely, several lines of gas burners, providing their uniform heating of water in the heat exchanger.

6 – water unit, which includes, among other things, a fitting for connecting a cold water main (pos. 9), a screw water flow regulator (pos. 9, not for all models), and a drain valve (pos. 10, also optional, not on all speakers).

Water valve - “frog”

The main element of a water node is always so-called "frog".

In essence, it is a working cylinder, the volume of which is divided into two parts using an elastic membrane.

Both halves of the “frog” are connected to each other by a fitting of a certain diameter. The point is that when water is opened through the column, due to the pressure difference in the two parts of this “frog”, the membrane bends upward and pushes the rod, which is connected to the spring-loaded gas valve, opening it. As soon as the water flow is stopped (the water tap is closed), the pressure under the membrane drops, the valve returns to its original position, and the gas burner, accordingly, immediately goes out.

11 - in this diagram - a unit with microswitches (optional).

12 – gas block with gas hose connection fitting (pos. 13). This is where the spring-loaded gas valve is located, connected by a rod (rod) to the water unit.

14 – in this column – the electronics unit that controls the operation of the water heater. In inexpensive simple speakers it may simply be absent. Pos. 8 – compartment for batteries (batteries) necessary to generate an ignition pulse on the igniter.

15 – connection fitting to the hot water distribution line.

16 – mechanical regulator that switches operating modes, controls the levels of water flow and gas supply. In modern speakers it can be completely replaced by an electronics unit, with control signals transmitted through push-button or touch control panels.

17 and 18 – cascade of column operation sensors. The specific “filling” may be different - this will be mentioned below in the article.

As already mentioned, any model may have its own distinctive features, but the basic principle of the structure still remains the same.

The diagram for connecting the column to the water supply pipes, regardless of its model, is the same for everyone - it is shown in the figure.

So, when you open the water at the hot water tap, water from the cold main begins to flow through the column. The pressure of the water flow opens the gas supply valve, which causes the burners to ignite (more on the ignition mechanism below). The energy of the combustion gas is converted into heating water - and water flows at the required temperature from the “hot” taps on the mixers.

This is one of the main advantages of a geyser - it works exclusively at the moment when hot water is required, the rest of the time being in “standby mode” or in the off state. The owners of the house (apartment) use hot water only when needed, and at the same time do not depend on work in any way.

The second main advantage is, of course, operating costs. So far, no other energy carriers can match the cost of natural gas.

The speaker, of course, also has disadvantages, and considerable ones.

It will not be possible to install it on your own - coordination with the relevant organizations, drawing up and approval of projects is required (unless, of course, the house was previously equipped with such water heaters).
The operation of the dispenser, even in its most modern version, still requires all residents to comply with certain safety rules.
A stock of heated water is not created, unlike an electric or gas boiler.
The initial installation of the column may involve very large-scale work to ensure the removal of combustion products or to create forced ventilation.

It should be noted that the designers of geysers managed to solve most of the “old problems” of gas instantaneous water heaters. Nevertheless, a certain number of people still have some kind of bias towards them. Therefore, in the next section of the article we will try to take a closer look at modern ones precisely in the light of persistent myths about their danger or inconvenience.

Modern geysers – should we be afraid?

An interesting feature of geysers is that, willingly or unwillingly, they can even change demand, and therefore prices, in the secondary housing market. Realtors won’t let you lie - very often one of the main issues during the initial consideration of proposals is connecting the house to a centralized hot water supply and, accordingly, the presence or absence of gas water heating systems.

It is characteristic that there is no unity of views on this issue. Of course, people, exhausted since childhood by the old Soviet ones, with their whims, noise, unsightly appearance, with constant “pressure” from elders about strict rules of use and the danger of violating them, do not want to hear about purchasing an apartment with gas water heaters.

However, there is also the opposite category - people who are already familiar with the fickleness of public utilities, with inflated tariffs and payment by meters for hot water (moreover, in order to wait for the first drops of hot water, it is often necessary to pour at least 3 ÷ 5 minutes of cold water, since the circuits circulation in many multi-storey houses are simply cut off). And such experienced clients, on the contrary, will be more satisfied with housing with a speaker. However, many people prefer to combine both possibilities - this is the most reasonable approach.

What are the main “myths” about geysers that continue to live, scaring away potential buyers of such equipment?

1. The column is very difficult to operate; it requires independent ignition with matches and constant monitoring.

Let's figure it out.

Well, firstly, any technique requires control, regardless of complexity. No one blames the gas stove with its open flame for this, or the faucet in the bathroom, which also needs to be monitored so that it does not leak over time.

Secondly, lighting with matches can only be found on those very “rarities” of the Soviet installation. Perhaps they are still produced somewhere, however, all, without exception, modern models worthy of mention are fired up differently.

— The simplest, “imperfect” modern speakers are equipped with piezo ignition. Before use, it is necessary to light the igniter wick by pressing the corresponding button, while turning the control handle to the appropriate position. Even this scheme is considered “outdated”, is used less and less and is giving way to other principles of ignition.

— Electric ignition is popular. At the moment the water starts, a sensor is triggered, which gives a signal to the electric igniter. At the same time, a channel for limited gas supply to the torch opens and a spark is generated to ignite it. The energy for sparking comes either from installed batteries (usually 1.5 or 3 volts) or from the power supply.

— Another modern method is the “HidroPower” system. A hydraulic turbine is built into the cold water supply pipe into the column. At a certain liquid pressure (usually about 0.3 - 0. 5 bar) the turbine induces an electrical charge sufficient to produce a spark for ignition of the igniter torch, which then it will transfer the fire to a common gas burner.

All this takes a long time to read - but in fact, the process of automatically igniting the flame when water is turned on occurs within just a few seconds.

So, in modern water heaters, no special human intervention is required (except for first opening the gas tap): turn on the hot water and use it.

By the way, you can immediately give an answer to a possible problem - why do you need an ignition burner (torch) at all? Surely it’s impossible to immediately ignite the main one?

It is forbidden! Until the torch warms up the sensor, the gas start solenoid valve will not operate. The very small amount that is taken at the moment of starting on the wick does not pose any danger to people - it will easily escape into the ventilation. But if suddenly the column accidentally goes out, the sensor has cooled down, then the gas supply will be blocked - the solenoid valve will close the line completely.

2. It is a very common belief that the column is a very explosive device.

What could explode there? If we are talking about gas, then it is no more dangerous in this regard than a regular gas stove. In the same way, provided that there is no leak, ventilation is normal, there is no place for an explosive concentration of gas to come from.

If we talk about the likelihood of an explosion of an overheated volume of water, then a boiler in this regard is probably even more dangerous. In the column, with its flow principle of operation, there are much fewer such conditions for an explosion. Moreover, in any (even the oldest and most imperfect) there are always at least two lines of “defense”, about which at or mentioned: an electromagnetic valve, which will not allow the burner to ignite independently, and a “frog” water valve, which shuts off the gas in the absence of water flow.

3. The fear is somewhat similar to the second point: there may not be an explosion, but a gas leak will lead to poisoning and a sad outcome.

You can refute it by citing all the same arguments that were presented two paragraphs above. And we can only add once again: the degrees of protection of a conventional gas stove are much lower, and the likelihood of a gas leak from the stove or oven into the living space is much higher. Nevertheless, for some reason, they are more afraid of gas water heaters in this regard, although this is completely illogical.

4. Another very persistent, but completely incomprehensible prejudice is that a gas water heater will completely ruin the interior of the kitchen.

Probably, only someone who can’t get the image of an old, rust-covered ancient pump with metal pipes leading to it in his imagination, can say this only.

Blaming modern geysers for being unsightly is the same as making similar complaints about refrigerators, microwaves, hoods, ovens, etc. Gas water heaters fit perfectly into the kitchen decor, take up very little space, and sometimes stand out against the general interior background just by the presence of a chimney pipe. (and even then - not always).

What else to consider when choosing a column

So, we come to a common opinion: there is no need to be afraid of geysers, they should become reliable and safe helpers in the household. This means that we should take a closer look at the criteria that should be taken into account when choosing this device in a store.

Gas water heater power

Under this parameter lies the ability of the geyser to heat a certain amount of water per unit of time to the required temperature. In general, the entire variety of these devices can be divided into three classes:

Low power geysers. The rating does not exceed 19 kW, and such a water heater is capable of serving only one point of consumption at a time.

Medium power speakers include devices rated from 20 to 28 kW. Usually they are already enough to simultaneously draw heated water in two places.

The most powerful are geysers that produce 29 kW or more. Their performance is even enough to take a bath in one place with simultaneous, for example, washing dishes in the kitchen, or with simultaneous using hot water in three places is quite enough for any “everyday” situation, even in a large country mansion.

It may be objected that kilowatts, although they are indicated in the product passport and on the information plate on the case, still mean little to the average user. It’s difficult to argue with this, so we’ll try to explain this meaning more clearly.

The main purpose of the column is to raise the water temperature from the initial value ( TVx) to what is necessary for domestic use ( TN). The difference between these two values (delta) will show what our water heater is capable of.

ΔТ = Тн - Твх

The “delta” itself is not interesting - you need to know how much water the column can heat for such a difference per unit of time. (usually measured in liters per minute).

How to determine the required power?

It can be taken as a statement that for the normal functioning of a kitchen sink, about 4 liters of heated water per minute are required. For taking a shower, 6 liters is usually enough. (These values have been tested in practice, and, by the way, they are what are used to guide the development of special economizer devices in the form of aerators or special fittings, which, even if desired, do not allow the use of larger volumes, thereby helping to save water).

The power of the required water heater can be calculated using the formula:

М = ΔТ × Σv/14.3

M – required power,

ΔT– heating value (see above)

Σ v– total volume of simultaneous consumption;

14,3 – coefficient taking into account the heat capacity of water.

Let's assume that a column is selected that allows simultaneous use of a shower and sink in the kitchen. The total volume will be Σ v= 4 + 6 = 10 l/min.

Magnitude ΔT– depends, of course, on the inlet water temperature. If we assume that water comes from a water supply with a temperature of about 10 - 15 ° WITH, then a rise of 25 degrees should be quite acceptable - the output will be about 40 ° WITH, which is enough for both taking a shower and washing dishes.

In total we get:

M = 25 × 10 / 14.3 = 17.4 kW

It is clear that this value is the lower acceptable limit. It is recommended to add another 15 - 20% reserve to it, and then round up to whole numbers. We get 21 kW. The speaker you purchase must have this power. Of course, all models of water heaters have their own gradations and capacities, but you need to buy one so that the value is not lower.

Perhaps this may seem too complicated. In addition, the initial temperature value may be different, for example, in winter, the water may have about 5 degrees at the inlet. In order not to force readers to “suffer” with formulas, it is better to provide a table in which the power of the column will be linked to the inlet temperature and the overall performance of the device, provided that it supplies water to the mixer at 40 ° WITH:

Temperature of tap water at the inlet to the column	The amount of water heated to +40 °C, depending on the power of the column (liters per minute)
	up to 3 kW	6 kW	8 kW	12 kW	15 kW	18 kW	21 kW	24 kW	27 kW
5 °C	1,3	2,75	3,6	5,5	6,75	8,25	9,4	10,75	12
10 °C	1,5	3,1	4,2	6,1	7,75	9,25	10,75	12,3	13.75
15 °C	1,75	3,6	4,75	7,25	9,0	10,75	12,75	14,3	16.2
18 °C	2,1	4,3	5,75	5,5	10,7	12,9	15,0	17,25	19.25

Usually both power and ΔT are the basic values of the water heater and must be indicated in the technical documentation.

And the most accurate calculation using the same formula will be possible with the proposed online calculator.

Using it is easy.

First, the temperature that is planned to be obtained at the output of their column is indicated. At the discretion of the future owner - for some, 40 degrees is enough, but maybe someone wants it cooler or, conversely, hotter.
The next step is to indicate the temperature of the water supplied to the column. Here you can proceed either from existing circumstances. For example, from some sources - wells, boreholes, storage tanks, water is supplied, regardless of the time of year, always at approximately the same temperature. And you can calculate it for the most unfavorable conditions, when the water in winter is so cold that it is not far from the freezing line.
Next, you need to indicate (check the boxes) those hot water collection points that, according to the owners, can be used simultaneously without interfering with one another. Of course, if you supply water to all plumbing fixtures at once, then you probably won’t find such a powerful device.

But this is all decided at home, so to speak, by administrative methods. And it’s difficult to imagine a situation where one family member, for example, is washing dishes in the kitchen, while a second one is standing in the shower stall, a third one is taking a bath, etc. And the calculator, by the way, will help you fully imagine what can be used at the same time.

All other values - the average statistical consumption at points of consumption and the heat capacity of water - have already been entered into the calculation program.
All that remains is to press the “CALCULATE…” button - and the answer will be given, expressed in kilowatts of the required thermal power of the column. In addition to the calculated value, another one will be shown - taking into account the 15% power reserve, since “driving” the water heater to the limit of its operating capabilities is far from the best solution.

Gas water heaters will effectively help heat water in the house. This will restore hot water supply in the event of a sudden or systematic shutdown. This rating of the best geysers for 2018 - 2019 makes it possible to choose a suitable model that has an excellent price-quality ratio.

The lack of centralized hot water supply is a problem only if the apartment or house does not have a good water heater. The geyser provides optimal comfort, it is reliable and powerful, and allows programming according to a number of parameters. But there is a huge selection of equipment on sale, which can be difficult to navigate. Next, you will find out which is the best and most reliable geyser, what parameters to pay attention to when choosing, whether it is worth paying for the brand.

How to choose

A good geyser is one that meets the needs of a specific buyer. Equipment may have different parameters and features - they need to be taken into account and known. There are also many manufacturers on sale - there are lesser and more well-known ones, and the price range is wide.

Main characteristics for comparing the best geysers:

Power;
Burner type;
Ignition;
Safety.

A practical and reliable geyser must be powerful enough - in this case, it will cope with current tasks and will last the stated period of time.

Power determines performance - namely the volume of water that the device pumps in a given period of time. Conventionally, the best geysers are divided into 3 groups based on power - medium, low-power, and powerful. The general range of values is 17-31 kW. Be sure to take into account the approximate number of water intake points in the room. If there are a lot of them, it would be better to choose a medium or high-power unit.

The next parameter is the ignition type. Previously, they used matches and lighters, but now there are more options to choose from. Modern models require a fully automated system (the best geysers come with automatic ignition), in which batteries or turbines create the spark. To start a model with auto-ignition, you need to open the hot tap. Geysers with piezo ignition are also one of the best; they represent an average semi-automatic option. In this case, you will need to press a specially designed button - and the column will start working. Fuel consumption in models with semi-automatic activation is quite high, which is their relative disadvantage (the wick burns even after the flame has died out).

Special attention should be paid to the type of burner. The best option is with flame modulation, since constant power products will have to be constantly adjusted, adapting to the pressure parameters inside the system. The modulating power independently adjusts to the water jet.

The next point is safety. Modern models have a three-level set of protection, which is triggered when the flame disappears or reverse draft develops, which should not exist. Separately, hydraulic valves are provided to prevent overheating.

Important! Various options for removing combustion products are available. The main ones are through a chimney or in a turbocharged way. In the first scheme, everything goes out into the street, in the second - into an equipped chimney. Both options can be implemented in a house; a chimney is not installed in an apartment.

Analysis of popular models of geysers: rating (TOP best)

Which geyser is better and how to choose is a question that interests every buyer of this equipment. Experts compile popularity ratings that will help you decide. They include the best geysers for homes and apartments from the perspective of consumers and experts. So, the most modern and reliable geyser - compare, analyze, choose.

How to make the best geysers work as efficiently as possible

We work at low pressure and will be better for an apartment or house, now let’s see how to increase their operating time.

Entrust installation, connection, commissioning of installations to qualified craftsmen. The quality of equipment service depends on how correctly the settings were made.
The output temperature should not be more than 60 degrees; for some models the maximum limit is 40 degrees. If you ignore the requirement, scale will begin to accumulate on the membrane.
For hard water, a system against salt deposits can be installed in the water heater. Its arrangement costs little, but it will avoid many problems.
While the boiler is operating, temperatures cannot be adjusted, especially by opening a cold tap. This will end with the formation of excess steam in the system, and the pressure will increase to critical levels. Water leaks are possible.
The heat exchanger and igniter should be cleaned regularly to remove blockages resulting from the accumulation of combustion products.
It is important to monitor the water pressure in the system - if it is low, then install an additional pump.

Preventive measures are simple, clear and will prevent unnecessary breakdowns. Modern geysers have an impressive service life and are able to work much longer than the period stated in the manual.

conclusions

Gas water heaters from Vaillant, Electrolux, Zanussi, Bosch, Termaxi, Beretta, Vector and some others have proven themselves in the market, have high reliability and a solid service life. To choose the best gas water heater with automatic or piezo ignition, you need to compare the characteristics and features of different models. All water heaters presented in the rating are of high quality, but not everyone is suitable for hard water and low pressure. When analyzing prices, you need to take into account both the cost of the installation itself and the costs of its maintenance.

The common term “gas water heater” refers to a gas instantaneous water heater - a household appliance that provides the preparation of hot water by heating it with a gas burner. This equipment is used in many houses and apartments. Geyser, which is better and which is worse - reviews from customers and specialists presented in our review will help you understand these issues.

Gas water heaters, their types and choice

It can be difficult to choose a geyser for an apartment or private house - this is due to the variety of models, which often do not differ from each other or have minor differences. Consumers are also confused by the opinions of sellers that do not always agree with each other. Some of them praise certain models, others praise competitors' products. As a result, buyers, unable to stop their choice, begin to study reviews of geysers.

Expert reviews can be more useful than any other information, because they are given by those who have already encountered certain models. Let's see what properties the hypothetical most reliable gas water heater should have:

No breakdowns throughout the entire service life;
High-quality heat exchanger;
No leaks;
Accurate operation of electric ignition;
Minimal maintenance required;
Stable operation even with fluctuations in water and gas pressure.

Some geysers have a long service life, while others begin to act up from the first day of operation.

Sometimes it happens that devices from leading brands break down almost every day, while cheap Chinese geysers (for example, some Vektor models) work like a good Swiss watch.

Let's look at the main types of geysers:

Domestic and foreign consumers tend to choose imported models, often ignoring Russian-made models;
With electric ignition, piezoelectric ignition and hydrodynamic ignition;
With flame modulation or simple mechanical control - the former are distinguished by maintaining a stable temperature;
With open and closed combustion chambers;
In terms of performance, geysers are available for sale, providing from 5 to 25 liters of hot water per minute.

When developing geysers, manufacturers use various technological solutions, which affects the reliability of the design. And here there is one small rule - the more expensive the device, the better it is. There are exceptions to the rule, so you should rely on it with caution.

Let's see how to choose the right gas water heater for an apartment or household, and what is best to pay attention to. This information will be presented in the context of reviews received from specialists and customers. The review will include models produced in 2016 and 2017, as well as samples released several years earlier, but still being sold.

Reviews from specialists and buyers

Choosing a geyser is not an easy task, because every consumer wants to have high-quality and reliable equipment at their disposal that will not be bothered by frequent breakdowns and leaks. Especially for you, we have compiled a unique rating of geysers in terms of quality and reliability, collecting the most popular models.

Alexander, 47 years old

The best geysers are made by the Conord factory. It probably couldn’t be simpler and more reliable. I bought the speaker for 4 thousand rubles. The Don water heater is lightweight and reliable, with a beautiful front panel and good performance. It is connected to a regular chimney, and its internal structure is simpler than a brick. Three years have passed since installation, during which time there has not been a single breakdown. It makes moderate noise, like any other model with an open combustion chamber. It’s easier to adjust the final temperature with a mixer to your liking.

Flaws:

Demanding on batteries - we tried using cheap batteries, they ran out in literally 3 weeks. Therefore, you have to buy expensive alkaline ones;
I didn’t really understand the purpose of the “winter-summer” knob - as a result, the column works year-round in one position of this knob;
The adjustment knobs are not the most accurate - you have to suffer before you get the desired mode.

Russian gas water heaters are better because they are adapted to our conditions.

Efim, 34 years old

I was faced with the task of choosing a gas water heater for a private home. The double-circuit boiler was immediately brushed aside - I work in a heating equipment store and I know how much trouble this unit can cause. It is best to install a separate heating boiler in the house, and in conjunction with it a boiler and instantaneous water heater. I didn’t have room for a boiler, so I settled on a simple gas water heater. It does have some drawbacks, but I don’t see the point in overpaying 10-15 thousand rubles and getting about the same thing.

Advantages:

There are no unnecessary functions - believe me, all these additional options are not needed in most cases, you are unlikely to use them;
Quite quickly reaching the set temperature;
It ignites quickly and without making a noise.

Flaws:

Sensitivity to the temperature and pressure of incoming water - at the slightest fluctuation in these parameters, the outlet temperature begins to “float”;
It may go out when you try to add cold water with a mixer - this happens when you suddenly open a “cold” tap.

But in general, the device is very good, it has been in the house for two years, there have been no problems so far. Although I know a lot of examples when complex double-circuit boilers began to fail in the second year.

Kirill, 34 years old

It’s hard to find a better one for an apartment than this geyser. One of the most reliable devices I have ever installed. The most difficult thing is to persuade the client to pay a significant amount for this model, since everyone is trying to save money. The manufacturer has done everything possible to make the water heater truly reliable. Inside we will see a durable heat exchanger that takes maximum heat from the burner. The unit is equipped with electric ignition, unlike older models that had an igniter. Therefore, now there is no need to fear for one’s own safety.

Advantages:

High efficiency - on average, this figure is higher than that of most models. In practice, this leads to savings of several percent on gas fuel;
A solid heat exchanger - this is not foil, but durable metal. As a specialist, I can say the same about the burner;
The desired temperature can be easily set without tedious turning of the knobs.

Flaws:

When you turn it on, sometimes it manages to overheat the water, so you don’t need to immediately put your hands under the stream - it’s better to wait a few seconds;
Older models use ignition with a pilot light, which can overheat the water even more during the initial start;
If you open two taps at once, the gas water heater may not be able to supply the required amount of water.

If you need a gas water heater for a private house or apartment, and you don’t want to waste money, it’s best to pay attention to this model.

Alexey, 29 years old

Our company recommends modern geysers for apartments and private houses. The time of using traditional units with simple mechanical controls has already passed. The future belongs to more advanced models with electronic control. A typical example of this is a device from Hyundai under the tricky name H-GW1-AMW-UI305. Its productivity is 10 l/min, the maximum heating temperature is +60 degrees. There is electronic flame modulation here - the geyser can independently maintain the set temperature. It also has a self-diagnosis system that detects breakdowns.

Advantages:

Stable outlet water temperature – forget about constant fluctuations;
Reliable heat exchanger - will last for several years without repair or replacement;
Convenient electronic control - just set the desired temperature and forget about further settings.

Flaws:

You cannot enable two parsing points at once - it is best to use them in turn;
It doesn't work as quietly as we would really like.

The main advantage is the optimal ratio of price, quality and functionality. There is nothing superfluous, there is flame modulation, a long service life - it’s simply not better to find.

The estimated price of this model on the domestic market is about 7.5-8 thousand rubles. It is better to buy a geyser in an online store, where its price may be lower.

Oleg, 30 years old.

My grandmother’s old Soviet-made gas water heater broke down - it often leaked, and during operation it hummed and made noise like an aircraft turbine. We went to the store to choose a new one. We put Chinese models aside, they are unreliable, often break, and the quality of their internal filling does not stand up to criticism. We settled on a model from the well-known company Ariston, with electronics. But they didn’t notice the expected quality, that China and Italy are all the same. Within six months, a puddle of water formed under the gas water heater, and then the controls failed. It would be better to take Bosch than this defect. Although they say that the quality of Bosch has also deteriorated, so it is not clear what is better now.

Advantages:

Compactness - the device is really small and neat, smaller than its Soviet counterpart, which went to the landfill;
The geyser is equipped with a fan, so interruptions in draft do not affect its operation;
It shows the temperature on the screen - you can’t imagine anything better, but previously you had to set the optimal temperature for water by touch.

Flaws:

Weak heat exchanger - leaked quickly;
I had to invite a specialist to install it - otherwise they threatened to void the warranty;
Lack of resistance to voltage surges - I had to buy an additional stabilizer;
We thought that it would work quietly, but that was not the case - it is noisy.

We spent almost 11 thousand, but received some kind of Chinese counterfeit. I advise you to better analyze reviews of geysers in the future so as not to buy a pig in a poke.

Mikhail, 38 years old

In the store we were told that it is best to buy geysers from domestic manufacturers - they say they are inexpensive, easy to repair, and work reliably. They recommended taking the VPG-6E model, and we decided to listen to the advice. This is not to say that the unit works without failures. Firstly, 10 months after purchase it began to drip - the heat exchanger had leaked. And secondly, without a display it turned out to be not very convenient to control the temperature. My cousin, who works as a heating engineer, said that it was better not to buy such equipment in the future - it is no different from Chinese heaters.

Advantages:

“Iron” ignition activation when opening the tap;
Small thickness of the case - only 14 cm;
Easy to install yourself - the device weighs only 6 kg.

Not the most successful model, there are better ones.

Vladimir, 56 years old

I work in a small store as a storekeeper, and at the same time I am responsible for the supply of equipment. We have Chinese geysers on sale, as well as their approximate analogues from the Neva brand. Lately we have been abandoning the cheapest models; people often complain about them, so we carry them less and less. The exception is the good model Neva Lux 5514. It has increased productivity, the weight is 12 kg - this indicates the use of high-quality components and a good heat exchanger (without saving on metal). As far as I know, complaints about this column are rare, even though many components are made in China.

Advantages:

Good work at two water points - productivity is 14 l/min;
Batteries last a long time, but it’s better to take good alkaline batteries rather than junk from stores with fixed prices;
It can heat water to very high temperatures, but it is best to limit it to reasonable limits so as not to damage the heat exchanger.

Flaws:

In order for the heat exchanger in a geyser to last as long as possible, it is best to place a good filter in front of it. Otherwise, it quickly becomes clogged or leaks form;
The model is noisy - it’s amazing how this can be achieved in our time;
I heard from people that the speaker can burn a little immediately after turning it on - it’s not very clear why this happens.

If you want to purchase a domestic geyser, it is best to choose this model.

Innocent, 46 years old

If you want to provide hot water to two water points at once, it is best to choose a gas water heater with good performance. I recommend the Bosch WR 15-2P model for purchase. Indeed, Bosch used to be much better, but compared to what the Chinese are doing, this speaker is simply a standard. It has certain disadvantages, which I will definitely tell you about. But it is a leader in terms of price/quality/functionality ratio. I recommend her to all my clients, rarely anyone is dissatisfied.

Advantages:

Does not make noise - this is a truly low-noise model. It lights up smoothly, without rattling or plaster falling off the ceiling;
The case does not overheat - therefore, the speaker can be used in the most intensive mode without fear of its failure;
It won’t scald your hands when you turn it on – here I’ll note a smooth increase in temperature, without jumps.

Flaws:

If the heat exchanger deteriorates, repairs will be expensive - this is the main disadvantage. In order for the geyser to last a long time, it is better to study the quality of the water and ensure its filtration;
The gas unit is weak - it is better not to adjust the temperature using the cold water knob, otherwise it may fail;
There is no automatic flame modulation - if it were here, it would be an ideal gas water heater.

Dmitry, 38 years old

When I arrived at the store, I immediately indicated to the salesperson that I wanted the model with maximum performance. The seller said that it is best to take a powerful device from Rinnai. I had to wait two weeks for delivery, since the model was not in stock - they rarely take it. But the wait was worth it, as this is truly the best gas water heater I have ever encountered. The water can heat up to a record +70 degrees, the combustion chamber is closed, so I didn’t need a chimney. There are smart electronics on board that monitor overheating and safety. You can safely leave a gas water heater in an unheated house, as it has protection against freezing.

Advantages:

Convenient digital controls - there are no outdated antediluvian knobs;
Capacity up to 24 l/min - if you open two taps, the temperature and pressure will not change;
There is a gas leak monitoring system;
Convenient temperature control using the display.

Flaws:

I had to call a specialist for installation, otherwise they would not provide a guarantee. Soon it will probably be impossible to change a light bulb yourself;
Expensive – I had to pay 35 thousand rubles for a gas water heater.

There are almost no shortcomings, the device works at 5+.

Igor, 41 years old

I devoted almost 15 years of my life to repairing gas equipment, including water heaters. Not long ago I got a job at an installation company, we do heating in houses, we install equipment for heating and hot water preparation. A couple of months ago, equipment was installed in a small low-rise residential complex. Boilers for autonomous heating were installed in each townhouse; Zanussi GWH 10 Fonte gas water heaters were used to organize hot water supply. This scheme ensures maximum maintainability and increases the reliability of heating and water supply systems - these are not double-circuit units that plague you with heat exchanger breakdowns. There were a lot of townhouses, but during the entire period of operation of the speakers, we received a complaint from only one homeowner - his heat exchanger was leaking. Well, factory defects always have a right to exist.

Advantages:

Affordable price - initially it was planned to purchase Chinese gas water heaters, but then they would definitely have bombarded us with rotten eggs and tomatoes. Therefore, we decided that it was better to go with Zanussi;
There is no problem with frequently leaking heat exchangers, despite their low cost. This is partly due to good water;
If something goes wrong due to small things, then repairing a geyser will not cost half of its cost - you can’t imagine anything better;
Accurate ignition, without pops.

Flaws:

When the pressure changes, it responds with a change in temperature - but this is quite expected;
It is not recommended to adjust the temperature with a mixer; it is better to do this on the gas water heater itself - this way it goes out less, although I consider this a disadvantage. After all, that’s why it’s a faucet, so that you can adjust the temperature yourself without jumping out of the bathroom into the kitchen;
For the correct operation of a geyser, it is best to purchase good, expensive batteries - this results in extra costs, but the ignition works more stably and for a long time.

It is better to take a gas water heater from Zanussi than from an unnamed Chinese manufacturer.

Video

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, the following aspects must be taken into account:

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

To begin with, in order to decide whether an automatic or semi-automatic gas water heater is better, you should briefly consider how each model works, as well as learn about the existing advantages and disadvantages. Only after this can an informed decision be made.

Column machine - what is it

Despite the stylish name, this term refers to a flow-type gas boiler, in which the burner is ignited using an electronic unit, without human intervention. Otherwise, automatic geysers work the same as semi-automatic ones.

All built-in functions: flame modulation, automatic temperature control 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 technical and operational characteristics of water heaters come from their internal structure. In other words, the operating principle of an automatic geyser directly affects ease of use, efficiency and other operating parameters. Turning on and off a boiler powered by batteries or mains power occurs as follows:

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 off are completely extinguished.

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 the outside of the casing there is 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

Automatic instantaneous gas water heaters have several positive aspects that explain their popularity and demand among domestic consumers:

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. Electronically controlled models are equipped with a touch panel, which adds even more comfort.

Boilers with a flame modulation function have automatic temperature control, but this plus also applies to similar models with semi-automatic ignition. If we talk about the disadvantages, then the price of the equipment comes to the fore. The cost of an automatic gas water heater will be 30-50% more. The reason for the high price is due to the ignition unit and electronic temperature controller present in the device.

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 production unit has failed.

Popular models of automatic speakers

Below is a list and brief description of the best water heaters, according to consumers. The top best speakers included exclusively foreign models, presented in premium and budget versions:

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 case is made 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.

The average cost of a machine column with flame modulation, depending on the manufacturer and the presence of built-in functions, is up to 30 thousand rubles. A budget atmospheric speaker is sold starting from 7-10 thousand rubles.

Semi-automatic dispenser - what is it?

As already noted, the main difference between instantaneous boilers is the ignition principle. The semi-automatic gas water heater has two burners. The main one works to heat water. The additional one is used as an igniter and burns constantly.

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?

There are no significant differences in the internal structure compared to automatic water heaters. The only difference is in the ignition features. Semi-automatic geysers work as follows:

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 structure are 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

Despite certain difficulties in operation, flow-through semi-automatic gas boilers have still not lost their relevance and are in constant demand due to several advantages:

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

Water heater malfunctions are rare. Breakdowns are mainly associated with wear of gaskets and debris in internal components due to poor quality water. There are only two disadvantages:

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 existing disadvantages make us think about the advisability of connecting a semi-automatic speaker. Despite this, as statistics show, about 35-40% of all speakers purchased by domestic buyers do not have automatic ignition.

The best models of semi-automatic speakers

Recognized leaders in the production of water heating equipment produce boilers with piezo ignition. The popularity of the speakers is ensured by their reasonable cost, simple and reliable design and trouble-free operation. Below is the top water heater, based on positive consumer reviews:

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 is a 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.

High-quality semi-automatic water heaters from a European manufacturer with flame modulation will cost only 10-12 thousand rubles, which is significantly cheaper than the cost of an automatic water heater.

Conclusion - automatic or semi-automatic?

There is no clear answer to this question. Otherwise, manufacturers would completely remove from production the type of water heater that is worse. Before making a decision, you should remember what is the difference between an automatic gas water heater and a semi-automatic gas water heater and compare the characteristics of both models:

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. An automatic gas water heater of 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.

Based on the criteria described above, it becomes obvious that it is better to buy a speaker that is suitable for individual operating conditions. If you don’t have extra money to buy a water heater, and the need to ignite the burner daily does not cause inconvenience or difficulty, you can safely purchase a semi-automatic boiler. Only when choosing, you need to pay attention to the fact that the design includes a flame modulation function. This way you can level out the gas costs associated with the constant operation of the igniter.
