Flowing gas water heater. Choice of geyser for heating water. According to the power of the column are divided into several types

Branded cheap water heater has high performance, has stylish original body, is one of the necessary design elements of the interior of the room. In the rating of water heating devices, they are very popular cheap flow gas boilers famous in the world trademarks: English Edisson, Italian Zanussi, Superlux, German Bosch, Vaillant, Roda, Russian Gazlux, Neva, Serbian Gorenje. A high-quality, inexpensive flow-through type household gas water heater is able to provide a draw-off point hot water in unlimited quantities. Also, a high-performance modern gas boiler can be used as a powerful auxiliary heater in an autonomous heating system. The original device for heating water of this type is provided with a multi-level system safe operation for a long period, can work in several modes.

We recommend purchasing a high-quality flow-type water heater with a manufacturer's warranty in special stores or dealerships!

A common everyday situation: you decide to buy a household appliance for autonomous supply hot water but don't know which is better - geyser or boiler. Indeed, both types of heaters boast many advantages, although they work in different ways. To help you understand this problem, we will compare the pros and cons of various water heaters and find out which one is better to choose in a given situation.

Types of water heaters and criteria for their comparison

All water heating devices for household needs are divided into 2 groups: storage boilers and flow-through water heaters. The first are a tank of a certain volume, where the water is heated different ways up to a maximum of 75 °C, after which it can be used. Flow heaters (they are also columns) are designed to “on the go” raise the temperature of the flow passing through the heat exchanger.

The main element of the storage water heater is a tank with a capacity of 35 ... 200 liters

The stores sell 3 types of water heaters for private houses and apartments:

  • electric and gas water heaters;
  • storage boilers running on electricity or natural gas;
  • boilers indirect heating.

Usually users are interested in which option is better - a geyser or electric water heater as these 2 varieties are the most popular.

The secret of popularity is quite simple. These household appliances are superior in their qualities to the rest: they are more reliable, efficient and cheaper. It is more difficult to install an electric column - the device consumes more power, so it is not suitable for installation in an apartment with old wiring or with a low electricity limit.


Due to the absence of a tank, the dimensions of the flow heaters are much smaller

Gas storage water heater for hot water also cannot be attributed to the demanded household appliances. The column is more convenient to use, and it’s easier to put it up. In turn, the indirect heating storage boiler is used in conjunction with another heat source -. These hot water tanks hold 100…300 liters, take up a lot of space and are available in 2 versions: floor and wall.

We will compare an electric boiler and a geyser according to 3 criteria:

  • equipment price;
  • complexity of installation;
  • convenience in operation.

But first, it does not hurt to analyze all the advantages and disadvantages of these water heaters.

Pros and cons of electric boilers

The principle of operation of these devices is as follows: the entire volume of water in the tank is heated by an electric heating element to the temperature set by the user. Her optimal value- 55 °С, maximum - 75 °С. For heating from scratch, it takes from 1 to 3 hours of time, depending on the initial temperature in the water supply.

When the maximum temperature threshold is reached, the electric boiler is able to immediately provide a large flow of hot water with a simultaneous request from several consumers. The duration of operation before cooling depends on the capacity of the tank and the flow rate. Considering these features, we list strengths storage heaters powered by electricity:

  1. The ability to satisfy the request for high water consumption from several consumers at the same time.
  2. The operation of the device does not depend on the pressure in the water supply and the initial temperature of the water.
  3. Installing and connecting a boiler is much easier than any other water heater. No permits are required for installation, chimney ducts and ventilation with triple air exchange are also not needed.
  4. Long service life. In most models from different manufacturers, the heating element is protected by a ceramic shell and will not burn out from scale formation.

Reference. The theoretical efficiency of electric heaters is traditionally the highest, efficiency = 99%. Although in practice, in comparison with this advantage, it is difficult to assess.

The weaknesses of the storage type water heater are the limitation of the total volume of hot water supplied and the long time for heating the next portion, when the stock in the tank has been completely used up. The disadvantage can be aggravated by the wrong choice of a boiler by volume, then 2 options are possible:

  • a device with a tank that is too large takes longer to heat up, and in standby mode it wastes more electricity;
  • a small container is an insufficient supply of hot water, which is not enough for all needs and you will have to constantly wait until a new portion is heated.

The last significant drawback is the significant size of the storage tank, which plays a big role in the apartment. It is not easy to allocate space in the kitchen or in the bathroom for an apparatus with a capacity of 80 liters, because approximately the same volume is needed for a family of 4 people.

Advantages and disadvantages of gas water heaters

The strength of domestic flow-type gas water heaters lies in the ability to instantly heat water, one has only to open the corresponding tap on the mixer.

Moreover, the column continues to supply hot water indefinitely while the valve is open. It is these qualities that make flowing gas heaters so attractive in the eyes of users.

Let's pay attention to other advantages of gas water heaters:

  1. Models with an open combustion chamber do not depend on the supply of electricity.
  2. turbocharged vehicles with closed camera economical and efficient, as they are equipped with a multi-stage or modulating burner, whose power is automatically regulated depending on the load.
  3. The gas heater takes up little space due to small size. Harmoniously fit it into the interior of any kitchen - no problem.

The very best speakers are not as efficient as electric heaters. Their efficiency does not exceed 90%, although in practice this is imperceptible.


The flow apparatus is equally easily placed in the boiler room of a private house and in the kitchen of an apartment

You ask: if everything is so good with gas water heaters, then why do many owners of private houses and apartments buy and install electric boilers? This is due to the shortcomings of the columns, of which there are few, but they are quite significant:

  1. The device gives out the amount of water indicated in the passport, heated by a certain amount (delta). For example, a gas column Neva 4511 with a power of 21 kW can provide a flow rate of 11 l / min when water is heated by 25 ° C. If water with a temperature of only 10 ° C enters the house, then heating it to 35 ° C will be enough for only one consumer. And at a delta of 40 ° C, the flow rate becomes much less - 7 l / min. To increase it to at least 8.5 l / min, you need more power - 28 kW and a more expensive heater.
  2. A geyser cannot simply be bought, installed and connected. It is necessary to coordinate the installation of gas-using equipment with management company and complete the project, and to connect, hire an installation company whose staff has the appropriate "crust" and permissions.
  3. When gas is burned, combustion products are formed that require discharge into or through a coaxial pipe.
  4. If the pressure in the water supply drops below a certain level, the water heater will turn off.

A chimney is required to remove combustion products from the column

Now that all the pros and cons are well known, let's move on to choosing a water heater.

What to choose - a boiler or a column

The first thing that worries the average user when choosing any product is the price. But an electric storage water heater and a geyser are completely different devices in terms of the principle of operation. This means that a comparison of their cost can be made only on one basis - the ability to provide hot water to a family of 3 people.

For example, let's take fairly reliable devices of the middle price category - a flow heater from the NEVA brand and a 50-liter Gorenje boiler. That's what came out of it:

Notes:

  1. If we take for comparison a geyser from the Gorenje brand, then it will cost even cheaper than the Neva - about 135 USD. e.
  2. The table gives the electric power of the boiler, but it is almost equal to the thermal one.

Conclusion. At the price of the equipment, a hot water column powered by natural gas clearly wins.

Comparison in terms of installation and connection complexity

This criterion plays an important role, because it is associated with certain costs - financial and time. When comparing, we will not take into account the supply of cold and hot water, it is present in both cases. Features of the installation of different water heaters are described in the comparative table:

Conclusion. Although some difficulties arise during the installation of a heavy and dimensional boiler, in general it is much easier and cheaper to install and connect it than a geyser. The accumulative heater, if desired, is placed with your own hands.

Convenience during operation

After analyzing all the pros and cons of operating household water heaters, we will collect them in one list:

  1. The column heats the water immediately after opening the tap, which is very comfortable. The boiler takes time to prepare water - from 1 to 3 hours, depending on its temperature and the volume of the tank.
  2. The accumulator gives a large flow rate and provides several consumers at once. When drawing water at 2-3 points, the column does not have time to heat the water and its temperature drops.
  3. The flowing gas heater heats water indefinitely. The duration of the supply from the boiler depends on its capacity.

    4. Speaking about operation, we should not forget about the maintenance of equipment. In this regard, a storage electric water heater is more reliable, since it only needs periodic cleaning of the tank and replacement of the anode. Geysers are complex devices, and not everyone can repair them.

    Conclusion. enjoy flow devices nevertheless it is more convenient provided that they have enough thermal power for all needs. Another thing is maintenance and repair, in this regard, the maintenance of the boiler will be cheaper.


    Work on servicing a gas-using water heater should be entrusted to a specialist

    So what is better to choose - a flow or storage heater? The answer depends on many conditions:

    1. If you are limited in time and money, it is better to install a boiler. The higher price of the equipment is compensated by the costs of connection and execution of documents required during the commissioning of the dispenser.
    2. When in an apartment or private house gas is not supplied, it is pointless to buy a flowing water heater.
    3. With high water consumption for the needs of hot water supply, it is more comfortable to use a boiler, you just need to clearly guess the time when it reaches the maximum temperature.
    4. Having no more than 2 points of water intake (for example, in an apartment) and also successfully guessing with the order of use, you can just as successfully use a gas column for heating. This is more convenient than waiting for the 50-liter tank to warm up.
    5. The geyser is the only alternative when the electricity limit does not allow connecting the heating equipment to the network or there are frequent shutdowns.

    There is another factor that can be regarded differently - the price of gas and electricity. AT Russian Federation the cost of gas is low, and therefore it is more profitable to put a column. In Ukraine, the picture is different: there the price of natural gas is comparable to electricity, any gas-using equipment will begin to significantly "hit the pocket" of the owner of a private house or apartment.

A geyser will not only allow you to use hot water from several sources in one house and not depend on problems or failures in the central system.

Flowing gas most often have small dimensions, they are an ideal choice for a small apartment. The device is connected directly to the cold water supply system, it works on both natural and liquefied gas.

The principle of operation of the column is very simple: water enters the heat exchanger, where it is heated by the combustible gas, and is immediately fed into the mixer.

The accumulative geyser can accommodate a large number of liquid, so it requires a lot of space. The heater heats a certain amount of water in the tank and keeps the temperature for a long time.

If the water cools down, the column automatically heats it up to the desired temperature. The water tank is well insulated, so the water stays hot longer.

Depending on your needs, you can choose gas water heater with a reservoir for liquid from 50 liters and above.

  • Power. Depending on how much liquid is heated, the geyser can have a power of 6 to 30 kW.
  • Ignition type– can be automatic and semi-automatic. Automatic type The ignition is triggered when the water supply is turned on or when the water in the tank has cooled down.

The semi-automatic type of speakers works only if the piezo ignition button is pressed. Such a device increases the gas consumption, since the igniter flame must always burn.

  • Burner type- can be with constant and modulated power. Devices with a constant power are less convenient in places where the water pressure and, accordingly, the heating temperature often change.

The burner with modulating power automatically adjusts to the pressure of the water and maintains the initially set temperature.

  • Type of removal of combustion products. The chimney column is equipped if the corrugated sleeve can be brought into an existing chimney.

Turbocharged units are less popular as there is a risk of the outlets freezing when low temperatures. In this case, it is often necessary to drain the collected water so that the heat exchanger does not explode.

  • Security- the geyser is a dangerous device, so you need to pay attention to the presence of protective sensors and relays.

  1. Dimensions- if this item does not matter, you can choose a column, taking into account only the main characteristics and requirements. If the room does not allow you to install a large storage column, you can choose the most compact flow column.
  2. The form– if you hide the device in kitchen set, it is better to choose square shape required sizes.

The first geysers appeared in 1895 in Germany, and in Russia they began to be actively used only in the middle of the last century. At that time, the country was experiencing a boom in housing construction, and hot water supply and a private bath became indispensable attributes of a city apartment, but not all houses could be connected to the general system. It was then in Khrushchev and early Brezhnevka that they began to put columns - flow-type gas water heaters. The choice was small, and in terms of ease of use, the first units left much to be desired. Today, such devices have become more technologically advanced, functional and safe, and their range has grown significantly. Let's try to figure out how to choose a gas water heater for an apartment and a house, and figure out what parameters you should definitely pay attention to.

No. 1. Types of gas water heaters: flow and storage

Depending on the device, gas water heaters are divided into two types:

  • flowing;
  • cumulative.

Wall-mounted instantaneous water heaters are popularly called geysers. They are the most widespread. Accumulative type devices in domestic open spaces are practically not used.

Flowing gas water heaters

The geyser does not have a storage tank and is intended for instant hot water. Inside the unit there is a heat exchanger through which a water tube passes. Under the heat exchanger is gas-burner. As a result of gas combustion, heat is generated, which heats the water passing through the heat exchanger. Exhaust gases are collected in a collector and discharged to the street. This is circuit diagram operation of the column, but the features of the functioning of some nodes from model to model may differ.

In the simplest columns light the burner you have to manually, more expensive models have automatic ignition: as soon as someone turns on the hot water tap, the column will start working and turn off when the tap is closed. The water temperature can be controlled both by a simple reducer and by sophisticated modern electronics.

From the school chemistry course, you must remember that the combustion of gas requires oxygen, which is contained in the air. Simple household speakers are equipped with an open combustion chamber and get air from the room. Combustion products are removed either through a conventional chimney(option for private houses), or through horizontal pipe with forced draft fan. The latter option is used in apartment buildings.

Geysers are equipped multi-stage security system, therefore, they cannot cause any harm, unless, of course, the installation was carried out correctly, and you do not violate safety precautions.

Advantages of geysers:


Some manage to put a column even in rooms that are not connected to the gas pipeline, as there are models that allow gas bottle powered.

There are gas water heaters and cons:


Accumulative gas water heaters

Similar devices by design reminiscent of electric boilers. The difference lies only in the source of heat: instead of electricity, gas is used here. The basis of such a unit is storage tank where hot water is stored. A tube passes through the tank - this is a heat exchanger, inside which hot products of gas combustion move. A burner is installed at the bottom of the tube, where the combustion process takes place. In order for the gases, moving up, to have time to give up all their heat, the heat exchanger receives a complex structure with dividers.

The volume of the tank ranges from 50-500 liters, but the most common models are 100 and 200 liters. For a family of 2-3 people, a unit with a volume of 80-150 liters is suitable. The tank receives reliable thermal insulation, so a once heated supply of water can be stored for a relatively long time - there is no need to turn on the device each time.

To the main benefits storage gas water heaters include:

  • profitability;
  • availability of a constant supply of hot water;
  • the possibility of installation where the gas supply line is weak;
  • the ability to work with a large number of water intake points.

Similar units take up a lot of space, but this is not their main drawback. They are standing quite expensive, in our area they did not acquire distribution, therefore their range is extremely limited. Most opt ​​for flow heaters or. Due to the low popularity of this kind of units, we will focus on how to choose a geyser - a device with flow type heating.

No. 2. Power of geysers

The power of the geyser is indicated in kW. It is directly related to performance equipment and indicates how many liters of water per minute the column can heat. It is worth noting that the best geyser is not necessarily the most powerful device. It all depends on how many people live in the apartment, and how many of them can use hot water at the same time (or how many are installed). It is believed that one mixer is capable of passing 6-7 l / min. It is enough to multiply this parameter by the number of taps, throw in a small margin and get the result. Power is indicated either on the column itself, or in the technical documentation for it. For example, a 23-24 kW column allows you to heat about 14 liters of water per minute to a temperature of about 25 degrees.

According to the power, the speakers are divided into several types:

  • 17-20 kW - minimum power, sufficient to supply one point of water intake, i.e. it will be possible to either comfortably accept or wash the dishes - it will be difficult to do both at the same time. Their productivity is 9-10 l / min, no more. Option for a small family or one person;
  • 20-26 kW - medium power columns, heat 15-20 l / min and are suitable for heating water up to comfortable temperature for 2-3 points of water consumption. The most popular option;
  • more than 26 kW - powerful units for large families and private houses.

In pursuit of power, do not lose your common sense and do not forget to take into account the water pressure indicator. It makes no sense to take a column designed to heat 25 liters of water per minute if the water supply network is not capable of providing such pressure.

No. 3. Type of gas column ignition

The type of ignition is one of the most important parameters of the column. It depends on how often you will approach the device, as well as how safe and economical the process of obtaining a flame will be. So, one of the following can be used in geysers types of ignition:


Speakers with electric ignition can be divided into two types: volatile and non-volatile. In volatile systems, the ignition system is connected to the household power supply. If you live in a city apartment and do not experience any special problems with the supply of electricity, then this is quite a good option. In non-volatile electric columns, ignition can be implemented in several ways:

No. 4. Combustion chamber type

To choose a geyser, you need to pay attention to a lot of technical details, and the type of combustion chamber is one of highlights. There are only two options here:

  • open combustion chamber;
  • closed combustion chamber.

Speakers with an open chamber are the simplest and cheapest. They use air from the room in which the device hangs to burn gas. The fence is conducted through the holes at the bottom of the column. Such units are mounted in kitchens or in separate utility rooms (an excellent option for owners of private houses). The products of combustion are discharged through the chimney thanks to natural draft. Such devices are characterized by minimal noise during operation, but are more suitable for private houses, as they require connection to a chimney. In addition, in the room where the device will be installed, it is necessary to ensure sufficient.

Columns with a closed combustion chamber get air from the street. The chimney in such units is horizontal, goes out through the wall and is represented coaxial pipe(pipe within a pipe). Through the inner part of the pipe, the products of combustion are discharged to the street with the help of a fan, and air is supplied to the column through the outer pipe. You can install such a unit in any room, it is safer, but you will have to pay more for such a column, and the operation of the fan depends on the presence of electricity and is accompanied by a little noise.

No. 5. Removal of combustion products

Partially, we have already considered this issue above, but now we will stop in a little more detail. According to the type of carbon monoxide removal, columns are:

  • classic, with chimney. Great for homes that already have a chimney. Otherwise, it will have to be built separately. For residents apartment buildings in most cases, this option is impossible to implement;
  • chimneyless or turbine. The products of combustion are discharged through a pipe, a hole for which is made in the wall. The products of combustion are drawn out due to the operation of the fan.

The room in which the speaker stands must be well ventilated. If installed, you will have to equip them with a ventilation valve.

No. 6. Column heat exchanger type

The durability and wear resistance of the column is directly related to the material of manufacture of the heat exchanger:


It turns out that stainless steel and refined copper will be the preferred options.

No. 7. Water and gas pressure

Each column in the data sheet contains two main water pressure parameters: the minimum at which the unit will turn on, and the maximum - the pressure that the heat exchanger can withstand without losing integrity. It is advisable, before choosing a gas water heater, to clarify all the parameters of your water supply network. For city apartments where speakers are operated (and this is mostly stalin, i.e. old housing stock with worn out communications) it is better to choose a unit that can work with a minimum water pressure. Therefore, pay attention to those devices that can heat water at a pressure of already 0.15 bar.

High pressure can be destructive to the column, and water hammer, alas, is not uncommon. Purchase units that can withstand a short-term increase in network pressure up to 11-12 bar.

Also, don't forget to specify which gas pressure column can work. In domestic gas pipelines, the gas pressure is lower than in European ones (13 mbar versus 20 mbar), so when buying a column from a European manufacturer, you need to ask what market it was produced for and whether a gas reducer is installed in it in order to maintain constant pressure.

No. 8. Burner type and power modulation

Burners in geysers can be of two types:

  • with constant power. The simplest option, the main advantage of which is cheapness. When changing the water pressure, you will have to manually change the temperature on the column, and you can be tormented. If you do not change the temperature, then the water may flow at a scalding temperature. Let's say your neighbor turned on the water or someone let the water down. The water pressure has decreased, but the strength of the flame has remained the same, so the reduced amount of water that will flow through the heat exchanger will be heated to uncomfortably high temperatures;
  • with modulated power. Everything here is much more modern. You just need to enter the desired water temperature, and the flame power will be adjusted depending on the water pressure. This is the preferred option. Of course, water temperature control is present on all columns, but conventional devices cannot adapt to changes in pressure and gas pressure, and units with modulated power will produce water with exactly the required parameters under almost any conditions. Such speakers are more expensive, but in operation they are not only more comfortable, but also more economical.

Of course, a modulating burner would be the preferred option.

No. 9. Geyser security system

Many are still afraid to use gas water heaters. Real estate sales data show that apartments with similar equipment are 15% cheaper than similar ones, but without gas water heaters, and 70% of buyers do not even consider buying such a home. If you approach the selection and operation of the gas column wisely, then all risks can be minimized. It is important that the column automatically turns off when there is no supply of water, gas or the necessary draft, and does not allow poisoning. carbon monoxide. To do this, modern units are literally stuffed with all sorts of security systems:


No. 10. The best manufacturers of geysers

It is difficult to argue with the well-known fact that they produce high-quality, reliable and durable equipment. When safety and comfort are at stake, it is better to overpay a little, but sleep well, so we recommend pay attention to the gas water heaters of such manufacturers:


Finally, we note that there is no need to be afraid of gas water heaters - you just need to learn how to choose them correctly and monitor compliance with the operating rules.

Over 50 types gas heaters water you will find in the catalog of the online store "Plumber-Online". We offer flow and storage gas models for floor or wall mounting.

Depending on the power and productivity, gas water heaters serve from one to several points of selection. They create comfortable conditions for families from 2-3 to 7 or more people. The rated power of gas boilers for heating water is from 2 to 50 kW. The heating elements are heating elements and heat exchangers. Auto ignition in domestic gas water heaters is carried out in the following ways:

  • electronic;
  • piezo;
  • piezoelectric.

Taking advantage gas heater water, you do not have to waste time waiting. Immediately after turning the tap, the equipment will turn on and hot water will flow from the tap.
