How to choose the right gas water heater, taking into account all the parameters. Which geyser is better? Reviews from experts and owners

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, repairs, accidents and the like.

It is no secret that not only the owners of private houses, but also the owners of apartments in high-rise buildings have recently increasingly installed their own, independent systems home heating and hot water supply. About heating boilers - 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 for your household hot water.

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 work uses the same principles and internal structure, and functionality.

The diagram shows the approximate structure of a typical modern flow-through gas heater. Of course, specific models from various 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. May be different principles actions - this will be discussed below.

5 - gas burner, more precisely, several lines of gas burners, providing0 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 connection to the disassembly line hot water.

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-buttons or touch panels management.

17 and 18 – cascade of column operation sensors. The specific “filling” may be different - this will be mentioned later 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 in any way on the operation of the boiler rooms.

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 a water heater, 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 speakers precisely in the light of persistent myths about their danger or inconvenience.

Video: general structure of a typical gas water heater

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 who have been tormented since childhood by the old Soviet speakers, with their whims, noise, unsightly appearance, with constant “pressure” from elders about strict rules of use and the danger of violating them, they don’t 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 off 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.

- One more modern method is the "HidroPower" system. In the supply pipe cold water a hydraulic turbine is built into the column. At a certain liquid pressure (usually about 0.3 - 0. 5 bar ) turbine induces electric 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're talking about 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 same 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- much less, and the likelihood of a gas leak from the stove or oven into the living quarters 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 geyser will completely ruin the kitchen interior.

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 Another thing 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 assistants in 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:

Gas water heaters low power. 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 as a guide when developing 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 the water comes from the 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 time 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:

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 not difficult.

• 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.

Calculator required power geyser

In apartments there are often interruptions in hot water supply; in general, it is necessary to create a individual system. To organize an uninterrupted supply of hot water, the best solution There will be an instantaneous water heater installed, but first you need to select it.

A good option is a gas water heater. Which one is better, reviews from experts and consumers will help you find out about it.

Why is a gas water heater better for heating water?

A device for heating water by burning gas (natural or liquefied) is called a gas water heater.

The resulting water can be used for economic, domestic or technical purposes. Note!

The gas unit provides hot water supply around the clock and uninterruptedly.

Depending on their design, heaters are divided into flow-type and storage-type devices. Geysers are instantaneous water heaters. They are more economical compared to electrical appliances, due to gas tariffs.

The device consists of a steel body to which water and gas are supplied. Inside the unit there is a spiral-shaped heat exchanger (coil) and a gas burner. The heated water is sent through a pipeline from the column to the tap. Gas combustion products are discharged into the chimney.

The igniter on the device can be ignited in three ways:

• manual option;
• electronic;
• piezo ignition.

In the first case, matches are required, and the main burner is ignited by turning the handle. Such variants of units are long outdated. Modern geysers are equipped with an electronic control system and are capable of operating automatically. The consumer only needs to open the tap, and the unit will turn on; after the valve is closed, the burner will go out.

When using a device with piezo ignition, for initial activation you must press a special button located on the front of the device. The resulting spark will ignite the pilot, which will ignite the burner. After turning off the water, the burner will go out, and the pilot light will continue to burn continuously.

What you should pay attention to when choosing a device

Before choosing a gas water heater, you need to decide on the power; it should be enough for all consumers. The higher this indicator, the more water volume the device will produce.

A 17 kW column provides 10 liters of hot water per minute - this is enough to wash your hands and take a shower. If you like to take a bath, then you should consider a 24 kW unit - it will produce 14 liters of water.

An important parameter is the ability of the device to heat water to a certain temperature. This indicator is denoted by the letters Dt. It is enough to raise the temperature to 37 degrees, and it can already be used. There are devices that heat up to 50 degrees, but their power will be greater, which means the price will increase.

The resulting water can be used for economic, domestic or technical purposes. When connecting multiple plumbing fixtures to the system, it is imperative to choose equipment of higher power.

An important addition are the unit’s safety sensors; they protect against such phenomena as:

• attenuation of the main and additional burners;
• overheating of the device;
• sudden cessation of water supply;
• fluctuations in water temperature;
• low pressure;
• spasmodic unstable combustion.

The design and placement in the room depends on the size of the devices. Most often, gas water heaters are installed in the kitchen, less often in bathrooms and toilets.

To understand how to choose a gas water heater, you need to know the features and advantages of different models.

Advantages of gas water heaters

Compared to electric water heaters gas appliances have a number of advantages:

• Heating occurs immediately after the burner is ignited, this ensures instant use of water without waiting for it to be heated by the heating element.
• Small overall size. The large dimensions of the boiler do not allow it to be placed anywhere. In addition, the speaker will look neat and not clutter up the room.
• Economical consumption of resources. Gas units They heat water as needed, so gas consumption is minimal. In addition, modern automatic gas water heaters have the ability to regulate power.
• The presence of sensors eliminates the possibility of gas leaks and makes the devices completely safe.

Top 10 best gas heaters according to users

To choose the right device, it is worth considering the rating of geysers based on their quality and reliability, compiled based on consumer opinions.

Among the most budget options can be attributed to this model. Ergonomic design and small dimensions will allow the device to fit into any style and interior design solution. Water is heated instantly. Protection systems will protect equipment from problems, and low cost makes it popular with buyers.

Gas is a dangerous fuel that requires serious consideration and increased attention. Negligence may result in a leak, resulting in an explosion.

Gas equipment must be installed correctly and connections must be taken care of to avoid an explosive situation.

Installation can only be entrusted to professionals, since experience and skill in such work are important. A gas heater is not a device that you can install yourself using instructions, but if the work is done correctly, it will serve you for a long time.

In addition, you need to know and follow the rules for using the device, otherwise any geyser - Mora, Ariston or Electrolux - will fail. You should not heat the water above 60 degrees, otherwise salt deposits will appear on the heat exchanger. This will result in the need to clean or replace it.

Attention! If you often have power outages, then you should stock up on IPS for automatic appliances. A voltage stabilizer will also not hurt, especially with frequent power surges in the network.

High water hardness can also lead to clogging of the device. To avoid this, use a special filter or means to soften it. You cannot disassemble and clean the column yourself - this is dangerous. Entrust such work better for specialists who will do all the work efficiently and on time.

Water heaters allow you to get hot water at any time, so they are often purchased for greater comfort in living in an apartment or house. Among them, geysers are the most profitable, however, modern devices of this type have a large list of characteristics, which can be difficult for the average user to understand.

Before you go to the store for such equipment, it is worth finding out what types of such heaters are available, as well as reading reviews from experts and consumers.

Kinds

Depending on power

• With low power (9-20 kW). Such devices are capable of providing warm water to only 1 point.
• With average power (20-24 kW). By installing such a column, you can count on simultaneous use of 2 points, but the intensity at them will be different (for example, the pressure in the bathroom will be stronger than in the kitchen).
• With high power (more than 25 kW). Such equipment is capable of supplying hot water to 2 points with equally high pressure or to 3 points with different intensities.

Considering the type of ignition

• With manual ignition. This is an inconvenient and outdated option that is becoming less and less common these days.
• With piezo ignition (semi-automatic). The burner inside the device is constantly smoldering, and ignition is ensured by turning on the button. Gas consumption is higher, but the dispenser itself is cheaper.
• With electric ignition (automatic). The most expensive, but also the most convenient ignition option, which uses a spark from batteries, and the burner in the column ignites when the tap is opened.

Depending on the regulation of flame combustion

• With automatic regulation. The most convenient option that ensures that a certain temperature is maintained despite changes in water pressure.
• With smooth regulation.
• With step regulation.

Depending on the exhaust system

• Turbocharged. Such equipment removes combustion products to the street through a special hole in the wall.
• With outlet to the chimney. In such a device, combustion products are discharged into a common chimney for the entire house.

Gas water heaters for apartments

Buying a speaker in city ​​apartment, first you need to decide on the power of the device depending on the needs for hot water.

Further, for a city apartment it is important to pay attention to the safety of the device. The homeowner must be sure that the water heater will not become dangerous for the apartment or its residents if the flame suddenly goes out or the water pressure in the pipes changes. In addition, you should find out in advance about all permits for installing the column. Sometimes it is necessary to obtain approval not only from the gas service, but also from neighbors.

When choosing equipment that will heat water for both showering and washing dishes at the same time, look for more powerful speakers.

Reviews

When assessing the power of modern water dispensers, users and experts give preference to medium-power devices that can supply hot water to 2 taps.

When discussing manufacturers, most buyers speak well of the speakers of such foreign companies:

• Ariston - the equipment of this Italian manufacturer is called high-quality, and its prices are considered acceptable.
• Vaillant - everyone likes the large number of options in devices of this brand, as well as high quality devices.
• Beretta – what consumers like most about this manufacturer’s models is design and reliable performance.
• Bosch - people are attracted to the good reputation of the brand, so such speakers are in demand for their safety and simplicity. Plus, they have a fairly affordable price.
• Termaxi - devices from this company are attractive due to the presence of a modulating burner. Modulation is also found in models Neva 5514, Beretta Idrabagno, speakers from Junker and Vaillant.

Attitude to Russian manufacturers ambiguous, but almost all consumers note that the higher the price domestic apparatus, the better its characteristics. Some buyers are satisfied with the long service and decent quality domestic speakers . Others like the availability of components and repair work . Those who respond to heaters Russian production negative, note short term

battery life, column sensitivity to water pressure, frequent breakdowns. It is also important to follow the instructions when using it, and if any problem appears with the column, immediately contact technical service. In most cases negative experience

As for the type of arson, consumer opinions regarding it are very different. Most buyers call piezo ignition the most reliable and practical, but note that electric ignition is more convenient to use. At the same time, users confirm that devices with electric ignition are more capricious in terms of water pressure.

But starting with a hydrogen generator causes a negative reaction among many consumers. Almost all of them note that with this, the most modern form ignition, you have to additionally install a booster pump and listen to neighbors' dissatisfaction about the low water pressure in the common riser.

When buying a Russian water pump, experienced users and experts advise additionally installing a pump to maintain sufficient water pressure in the pipes. For very hard water, installing a filter is also recommended to prevent scale formation and damage to the heat exchanger.

For information on what you should pay attention to when buying a gas water heater, watch the video of the Heat Engineering St. Petersburg channel.

How to choose a gas water heater and what criteria should you follow when making a purchase? This question interests many people who want to provide their home with hot water supply. Plus, this equipment is considered the most economical and it can simultaneously serve two or three water intake points. Let's figure out which manufacturers are better and what to look for when you come to the store.

Features of this equipment

Choosing a gas water heater is a responsible process, so first you need to figure out why this equipment finds wide application both in houses and apartments? To do this, let’s name the main advantages of speakers:

• ease of operation;
• aesthetic appearance;
• durability, safety of use;

Compared to storage equipment (boilers), geysers have acceptable dimensions and are not inferior to them in performance. Current technologies make it possible to create reliable, highly efficient devices characterized by uninterrupted operation.

Without quality technical equipment modern life is unthinkable, since people are accustomed to comfort and want to enjoy the benefits of life to the fullest. For this reason, people do not want to depend on the utility service and install a gas water heater in their apartment. There is also a fact of saving energy costs, because the equipment in question “absorbs” less money than electric water heaters.

The geyser is mounted at an accessible height in accordance with the installation instructions - each model has its own

What criteria should you pay attention to?

Which geyser to choose? So that our readers who are faced with this problem do the right purchase, in this article we will try to provide the most relevant and comprehensive information.

So what should you pay attention to?

First aspect– power. The overall performance of the system depends on this important parameter, because we are talking about a certain amount of water that the device can heat per unit of time. In this regard, geysers come in three types: low (17-19 kilowatts), medium (22-24 kilowatts), high (28-31 kilowatts) power. The choice of a specific model depends on the following factors:

• individual user needs;
• number of water intake points. For example, if you plan to consume at several points, you need to give preference to higher power and good performance.

Second aspect– type of ignition. Gone are the days when a geyser was lit with matches, because today it is an improved equipment: you just need to open the tap and the device will work. Automatic ignition is the most reliable and this statement is supported by significant arguments. The bottom line is that the spark is created using a turbine or batteries, and the wick is ignited only by direct consumption of water.

As for piezo ignition, this method is quite common, but somewhat inconvenient. Why? Because ignition is carried out by pressing a button, that is, if the column is located in hard to reach place, this button is difficult to reach. In addition, after ignition, the wick continues to burn, consuming gas.

Third aspect– burner type. When answering the question of how to choose the right geyser, one cannot fail to mention this criterion. A constant power burner requires manual adjustment. Everyone understands that there is no convenience here, since the water pressure in the system is constantly changing. But a burner with modulating power is much more practical: it adapts to the pressure of the water flow, ensuring a stable temperature.

Fourth aspect- safety. The best geyser has a three-level security system and is automatically blocked when the flame goes out, in the absence of draft, or when reverse thrust. It is also advisable that the equipment be equipped with a hydraulic safety valve that protects the device from overheating.

Fifth aspect– removal of combustion products. In principle, geysers are divided into turbocharged and chimney. In the first case, the equipment discharges combustion products into the street, and in the second, the column is connected to the chimney.

Sixth aspect- manufacturer. This is a broad topic, so we will look at it in more detail and present to your attention a unique rating of geysers.

Rating of the most famous manufacturers

Yes, the market range is very diverse, so deciding which geyser is better is not so easy. For this reason, we want to provide a list of manufacturers whose products are the most in demand:

• Ariston– devices from this manufacturer occupy a golden mean, because for quite reasonable money buyers can buy a decent Italian quality. Ariston gas instantaneous water heaters are characterized by high efficiency and are equipped with the function of maintaining a set temperature. The main components of the equipment are made of composite material guaranteeing long service life and corrosion resistance;
• Termaxi– geysers are made in China, but they are famous good quality. Their competitive advantage is the presence of a modulation burner. Also in the line of water dispensers there is a model that provides 12 liters of hot water per minute - this means that three water intake sources can be connected to the equipment;
• Vaillant– there is no doubt about the high quality of equipment from a German manufacturer, since geysers are characterized by reliability and unpretentiousness. They cause minimal problems for users and last a very long time because they are equipped with a durable copper heat exchanger.
• Beretta– instantaneous water heaters made in Italy have extremely positive reviews from consumers. Why? The reason is clear: ease of use, beautiful appearance, high quality components, wide range. For example, the model range includes devices with electric ignition and flame modulation.

We really hope that after reading our article, you will be able to purchase the best geysers for your apartment or house, which will best meet your needs and wishes.
