A geyser is a water heating device, usually a flow-through type, that uses gas to heat water. When apartment house often left without hot water supply, it is recommended to think about purchasing a unit that will ensure its uninterrupted supply. “Plumber Portal” will tell you how to choose a gas water heater for an apartment that will do its job efficiently and smoothly.

The gas flow model has all the advantages of its electric counterpart, but at the same time does not load the wiring. In apartments, instantaneous gas water heaters are usually used for preparing hot water, and in old two-story houses they can be used to maintain the coolant temperature.

Instantaneous gas water heaters can usually be found in older homes. Homeowners in multi-storey buildings, where there is a centralized hot water supply, are practically not familiar with this unit. But the inhabitants of Khrushchev buildings quite actively use these devices.

Instantaneous gas water heater or in simple words A geyser is a unit for preparing domestic hot water in a stream. Main design elements:

• heat exchanger - necessary to transfer heat to water from burning gas;
• burner;
• control, protective and regulating fittings - flow sensor, pressure switch, ignition device, temperature sensor, gas and water regulators, draft detector;
• smoke exhaust system.

Heating is carried out during the combustion of natural gas, which becomes impossible in the absence of oxygen supply and removal of combustion products.

The unit works quite simply - as soon as the mixer is opened, liquid begins to flow through the device, the burner lights up and the water is heated. From the consumer's point of view, the water heater of this type quite convenient - when you open the wound, hot water immediately flows.

Pros and cons of a gas heater

The question arises, which geyser is better, and what are the advantages of this design? Choosing a gas water heater: advantages over an electric one:

1. Power outages (frequent in rural areas) do not affect the operation of the unit.
2. Electrical wiring in old Soviet houses will not be able to cope with the load with the mass installation of electric water heaters.
3. Gas is cheaper than electricity. When heating 1 m3 of water, 9 times less money is spent than when heating using electricity.
4. Compared to its electric counterpart, gas is capable of serving several hot water points.

The downside of these water heaters is the need to install a ventilation pipe. The disadvantages also include monitoring the status of the device. The devices are very sensitive to pressure changes in the natural gas supply source.

1. Gorenje GWH 10 NNBW - price up to 20,000 rub.
2. Beretta Idrabagno Aqua 14i - price up to 25,000 rub.
3. Bosch WRD 13-2G - price up to 22,000 rubles.
4. Mora Vega 13 - cost up to 20,000 rubles.
5. Ariston Fast Evo 11C - price up to RUB 13,060.
6. Zanussi GWH 10 - cost up to 12,000 rubles.
7. Electrolux GWH 265 ERN Nano Plus – price up to RUB 10,000.
8. Neva or Neva 4510-M – cost up to 8,000 rubles.

These models received the most positive reviews from consumers who installed the device both in an apartment in a multi-storey building and in a country house.

Oasis devices are different original design, however, in terms of technical characteristics they are inferior to the models from the rating.

Types of gas water heaters

Gas water heaters are distinguished by the method of ignition. Due to the fact that the equipment represents a source of increased danger, the unit is equipped with an automatic shutdown function for the gas supply in the event that a backdraft occurs in the chimney and the wick collapses. There are geysers that require a spark to ignite after pressing a button, and there are devices where this function operates automatically.

1. Manual ignition gas water heaters. An old proven scheme: bring a burning match to a special window in the column where the gas is ignited. This method is always somewhat “exciting”, but modern units are much safer compared to their Soviet counterparts.
2. Gas heater with piezo ignition. To ignite the gas, you just need to press the button located on the front side of the column. The piezoelectric element inside produces an electric discharge that ignites the gas. Essentially, a piezoelectric element is a device that can last forever, so you don't have to worry about it ever running out like a battery.
3. Geyser with electronic ignition. This device is another monument to how laziness drives progress. The gas ignites as soon as the tap is opened.

According to the method of removing combustion products, columns are divided into:

• chimneys are the most optimal choice when the corrugated hose of the column is discharged into a chimney that already exists in the house;
• turbocharged - presents some difficulties during operation, since it is necessary to punch an outlet for the column in the wall, and because of this, the outlet paths may freeze in extreme cold and in order to prevent the heat exchanger from rupturing, it is necessary to constantly drain the remaining water.

Criteria for choosing a geyser

In an apartment where a chimney duct is equipped, it would be more rational to install a chimney gas water heater. Typically, such channels are installed in all high-rise buildings with gas stoves, in particular in “Khrushchev” and “Stalin” buildings. A pipe from the gas water heater is led into it, through which combustion products will be removed, thus protecting both the apartment residents from combustion products and the other residents in the house.

So, which instantaneous gas water heater should you choose? When choosing a geyser for heating water, before buying it, you need to pay attention to many parameters that directly affect the service life of the unit. Also one of key points When choosing a device, consider the available space in the apartment.

Hot water performance is also one of the important characteristics of how happy the unit can make you. How to choose a suitable geyser:

1. For a single person living with a single pet, a dispenser with a capacity of 10 l/min is suitable. and less.
2. A couple with a baby or pet can get by with a 9 l/min dispenser.
3. A family of three people and a pet or four people, two of whom are children – up to 15 l/min.
4. A large family of four people and several pets needs a unit with a capacity of 16 l/min or more.

The unit comes in three kW ranges: 17-19; 22-24, 28-31.

Low power device capable of supplying hot water only one point in the house, such as the bathroom or kitchen. If it is necessary to service several points, the column should produce at least 15-20 l/min. with a heating temperature of 35-40o C, the power in this case should at least be average.

The pressure inside the water supply system also plays an important role, since even a powerful unit will not be able to cope with its task if it is insufficient. Therefore, in this case, there is no point in purchasing a powerful, expensive unit.

The gas pressure in the system is perhaps the key parameter that needs to be paid special attention to. Domestic gas system differs from the European one in lower pressure: 13 mbar versus 20. Therefore, when purchasing a gas water heater from a European manufacturer, you need to find out which gas pressure scale is used for this device and whether it has a gas reducer to maintain constant pressure.

An equally important characteristic is safety. A geyser for a home or apartment is a highly dangerous device, a supply system for both water and gas. Because of this, devices are equipped with a variety of protective relays and sensors. When asking which device to take, you need to pay attention to the presence or absence of any elements in the chosen device.

The main such sensors are:

• ionization sensor – immediately shuts off the gas supply at the moment the wick goes out;
• combustion sensor - is a safety device in the case when the ionization sensor does not work, performing its work in the event of its failure;
• overheating sensor – prevents the water temperature from rising, thereby preventing rupture of the heat exchanger, and in addition neutralizes the likelihood of scale formation;
• flow sensor – serves for automatic switching on geyser, when the hot water tap opens and turns off when it closes;
• draft sensor - designed to block the activation of the unit in the absence of draft in the chimney, thereby preventing the formation of carbon monoxide in the room;
• temperature sensor – designed to control flame power;
• safety relief valve – protects the heat exchanger from damage by blocking the unit if the water pressure in the system increases;
• sensor low blood pressure water – blocks the column from turning on if the water pressure is too weak for its safe operation.

Remember! If the water hardness seriously exceeds the requirements of the instructions, it is necessary to install a water softener. High hardness provokes the formation of scale, which seriously reduces the service life of the device.

When can a column not be installed?

In a house where there is permission for installation gas equipment, such as slabs, installation of a column may be prohibited. This restriction applies to houses above 11 floors. Permission to install a water heater in such a building will not be issued by any regulatory organization, due to the potential danger for the people living in it.

In addition to the number of floors, permission may also be denied due to redevelopment. A studio apartment is also included in the list where a gas water heater cannot be installed, due to the fact that this equipment cannot be installed in sleeping areas. When the kitchen is combined with a living room, installing a gas water heater will also be prohibited. Before you start redevelopment, you need to remember these restrictions. All of the above can be attributed to apartments where there is no kitchen at all or it is shared.

If the house does not have the restrictions listed above, then you will need to collect a package of documents that are needed to register the unit. The procedure is as follows:

1. An application is written to the office that deals with gas distribution.
2. Get a plan from the BTI or Rosreestr.
3. Provide an extract from Rosreestr, which confirms ownership.
4. Contact the relevant organization to draw up a project.
5. Contact certified specialists from an organization involved in gas work.

After which the specialists crash into gas pipe, connect the device and hand over its operation. In order to determine the possibility of installation, it is necessary to carefully study the cadastral passport of the apartment. There you can find out about the parameters of the room where you plan to install the water heater.

It is absolutely forbidden to install this device yourself, disregarding the procedure established by law, no matter what your goal is. This can not only lead to a hefty fine, but also put the lives of others in danger.

Rules for installing the device in an apartment

Incorrect installation of a gas processing device can result in serious hazards. To eliminate the slightest risks, site consultants recommend thoroughly studying all the details and subtleties of the installation process.

The gas water heater must be installed in a room whose cubic capacity is more than 7.5 m3. The height of the room must be at least 2.0 meters. This height is optimal for the operation of the unit. The room must be glazed, and the window must not be blank, so that it can be ventilated in case of a leak.

The total glazing area, excluding the frame, can be determined by the formula:

C=O*0.03,

Where: C – glazing area, O – volume of air in the room.

The window should be able to ventilate the room in case of an emergency. As a rule, an ordinary kitchen fits these parameters quite well if it has a door. If not, you need to install it.

In addition, it is advisable to install a gas analyzer in the room. Thanks to it, gas leaks can be detected. This device It is not necessary to install, but it can be used to monitor the work gas devices. It monitors the level of propane in the air and, if detected, signals this.

The water heater must not be installed on load-bearing wall building. Because because of this, an explosion may damage or even destroy the entire building. To clarify this information, it is recommended to use the cadastral passport of the apartment or the general plan of the house. You can also check this information with specialists.

Requirements also apply to the distance from the column to the opposite wall. It should not be less than one meter. This is done to allow free access to the device during its maintenance and inspection. In addition, installing gas supply pipes into walls is prohibited.

The pipes located in the apartment belong to its owner, but making any changes to them is prohibited. Any changes must be authorized by the gas service, otherwise you may face a serious fine. If the column was already previously installed in this location, then this will not cause any special changes to the project. You can close the gas supply valve on the pipe and simply replace the device, or take it for repairs. When installing the device for the first time, it is necessary to make wiring.

Before self-installation pipes, the following rules must be observed:

1. Before starting work, turn off the gas.
2. Work must be carried out with open windows.
3. Debris that appears in the pipes during installation must be removed.
4. Pipes cannot be routed through windows and doors.
5. Prohibited use ventilation shaft for laying pipes.
6. The gas pipeline should not be installed in a wall.
7. The use of thin flexible hoses longer than 3 meters is prohibited.
8. Metal pipes must be pre-painted.

Particular attention should be paid to sealing the gas pipeline connection elements. For this purpose, sealant and sealant are used. After the wiring is completed, you can proceed directly to installing the device.

Thus, a gas water heater is an excellent alternative to electric storage water heaters. However, it is not enough to know how to choose a gas water heater for an apartment; to install it in a house, you must obtain the appropriate permission and invite a specialist to install and connect the device to the general gas main.

If you purchase a really high-quality water heater, you will always have hot water in the house, and this is also a fairly economical solution that can supply liquid to several water intake points at once. So let's find out what to look for when going to the store, and which manufacturers should be trusted.

Geyser or electric water heater - which is better to choose?

Each type of equipment has its own advantages, for geysers these are:

1. Beautiful design.
2. Simple and convenient operation.
3. Long service life.
4. Safety of use.

If you compare it with electric boilers, then it is worth mentioning the small size of geysers and their good performance. Modern technologies allow manufacturers to make high-quality and effective products that are safe to use, even despite their explosive fuel.

Without productive technology, human life is practically impossible, because we are all accustomed to comfortable conditions and the use of all the blessings of life. That's why the residents multi-storey buildings More and more people are refusing the services of public utilities and purchasing a gas water heater. The issue of saving is also important, because such a water heater will be cheaper than heating water from central systems or using electrical devices.

Equipment selection criteria

And yet, which boiler to buy? To make the right choice, you need to familiarize yourself with the main characteristics that will help you purchase the best option.

First of all, you need to pay attention to the power of the device. The overall performance of the equipment largely depends on this characteristic, because it determines the amount of water that the column can heat in a certain time.

According to this criterion, geysers are divided into three types:

• Low power (17-19 kilowatts);
• Average performance (22-24 kilowatts);
• With high power (28-31 kilowatts).

You need to choose a specific column depending on your needs and the number of water intake points in the apartment. If you need the ability to draw water from several points at the same time, then it is better to choose an option with medium or high power.

The second criterion for selection will be the type of ignition used. Once upon a time, ordinary matches or a lighter were used to ignite the column. If you come across such a “dinosaur” today, it is better to bypass it and opt for modern models. Now the dispenser has an automatic ignition system, the spark appears thanks to turbines or batteries, and the wick is ignited only when hot water is used. As a result, to start the system you just need to open the tap, and this is not only convenient, but also safer.

There is another one Alternative option– piezo ignition, it is quite popular, but not entirely convenient. The fact is that ignition begins when you press a special button, and if the equipment is installed in a hard-to-reach place, then it is difficult to press the button. Also, in this method, the wick will burn even after ignition, thereby increasing gas consumption.

When choosing a gas water heater, you cannot ignore the type of burner. Thus, a burner with constant power requires manual adjustment. It is clear that such a solution is not entirely convenient, because the water pressure is central system changes often. It is better to buy a burner device with modulating power; it will independently adjust to the power of the jet and ensure a normal temperature of the liquid.

Safety remains an important factor. High-quality equipment is equipped with a three-level protection system, and an automatic locking function when the flame goes out or when reverse thrust. Safety dispensers are also equipped with hydraulic safety valves that help prevent overheating.

Another important factor will be the removal of combustion elements. Here the speakers are divided into two types: turbocharged and chimney. In the first version, the device throws combustion elements into the street, and in the second, into the chimney system.

Besides, important criteria are the reputation of the manufacturing company, and, of course, the cost of the equipment, because no one wants to overpay. Therefore, it is important to buy affordable and high-quality equipment.

The gas equipment market today offers a large number of models of water heating appliances from imported and domestic manufacturers. Below we will discuss how to choose a geyser. After all, in order to choose a suitable device, you need to understand the features of different types of speakers and their characteristics.

Types of water heating columns

A gas water heater for an apartment is often chosen based on the type of ignition. Modern devices usually divided into two large classes:

1. Semi-automatic(piezo ignition), ignition of the pilot burner in which occurs from sparking when pressing a button acting on the built-in piezoelectric element;
2. Automatic, in which an electronic unit is responsible for supplying a spark to the ignition or main burner.

A spark in automatic geysers of different models can be generated in two ways - by a spark gap when powered by a pair of “D” size batteries (the largest battery) and by a small electric generator driven by a hydraulic turbine (hydraulic ignition).

Each column has disadvantages and advantages. Let's consider what you need to consider so as not to spend a long time choosing which geyser to buy in the store:

• The ignition burner of semi-automatic water heaters must burn constantly, otherwise the main burner simply will not light up when the water tap is opened, which entails a significant overconsumption of gas - in a day a small wick “eats” up to 0.8 cubic meters. m of gas;
• batteries of automatic speakers have to be changed periodically (about once a year), which is not always convenient;
• water heaters with a hydrogenerator are expensive, and the hydrogenerator is sensitive to water quality - if this device becomes clogged, the column will simply stop functioning.

And before you buy an automatic gas water heater with a hydraulic turbine, make sure that the pressure in your water supply is normal, i.e. above 0.4 atm, otherwise it simply will not turn on at low pressure. It is also useful for this type of speakers in the apartment to have additional system filtering tap water, i.e. . hydrogenerator operates at high water pressure and good water quality.

Nevertheless, the comfort of using automatic geysers determines the increased demand for them, even despite the high price. The “automatic machine” starts working immediately after the consumer opens the hot water - there is no need to press or set anything on fire.

Semi-automatic speakers have also still not lost their popularity, primarily due to their low price, simplicity, lack of expensive electronic components and high level of reliability. Therefore, consumers often choose these water heaters when answering the question of which gas water heater is best to buy.

Gas water heaters differ in the way they regulate gas flow. According to this parameter they are divided into the following types:

1. Speakers with automatic adjustment, in which the set water temperature is maintained constant by changing the amount of gas supplied to the burner in a fully automatic mode.
2. With smooth or step manual adjustment. The water temperature changes when its flow rate or gas pressure in the line changes, but the user has the ability to change the gas flow to the burner to maintain the temperature regime.

Manual temperature adjustment is done by turning the knob gas tap. If you twist it too much, the column may go out. Also, it is better not to operate such speakers in the mode of mixing heated and cold tap water, otherwise they will quickly fail.

Parameters for choosing a water heating gas water heater

To understand how to choose a gas water heater for an apartment, study not only the type of water heater, but also the parameters, the main one of which is power, usually expressed in kilowatts (kW). You can focus on the following statistics:

• to heat water only for a shower or sink, a low power column of up to 19 kW will be sufficient;
• if several water intake points must operate simultaneously, then it is necessary to buy a dispenser with a power of 22 kW or more.

Manufacturers usually indicate how much water the column can heat by 25 degrees in a minute. Here it should be taken into account that if the column heats a maximum of about 11 liters of water by the specified amount, then the productivity is only sufficient for one water collection point. A dispenser with a capacity of 14 liters can already work at two points, 16 liters - at three points.

You should not take a powerful speaker if the water pressure in the apartment is low - the device will still not produce the required power, and you will overpay. If the maximum flow rate in your house is, say, 10 liters, and you take a dispenser with a flow rate of 15-16 liters, then, depending on the manufacturer, the automatic or semi-automatic device will either heat the water ineffectively or will not turn on at all.

It is also important to correctly determine the overall dimensions. instantaneous water heater, for which measurements of the installation site are made. The diameter of the chimney to which the water heater is planned to be connected is also measured. If the need arises, you can purchase a special adapter to connect the gas water heater to the chimney.

Speaker for a private home

To know how to choose a geyser for your home, you need to understand what requirements these devices impose on the presence and properties of the chimney in the building, as well as on the quality of ventilation.

Gas water heaters work not only in apartments, but also in private houses. True, before installing a water heater in a private home, you need to decide how and where the flue gases will be discharged. If the house already has an exhaust duct with sufficient draft, then any type of instantaneous gas water heater will be suitable for installation.

In the absence of an exhaust duct, for example, in a five-story apartment converted to use water heating devices or in a private house, it is possible to use only parapet or chimneyless water heaters. In this case, combustion products are removed by a fan, for which a hole is installed in the wall. The room itself should also be well ventilated.

Also for private houses great importance will have a minimum water pressure value at which the column can turn on. As previously noted, the highest minimum pressure required for the operation of the column are automatic models with a hydrogenerator. For them, this value corresponds to 0.35-0.45 atm. It is better to choose water heaters that operate at 0.1 atm.

The best models of geysers

Below are the characteristics and description best devices offered on the market today. This way you can roughly figure out which gas water heater to choose.

One of the best inexpensive economy class geysers with an open combustion chamber, automatic electric ignition from batteries, but with a minimal set of functions. Produced since 2009 in St. Petersburg by the Gazapparat plant. There is no outlet temperature control, and the maximum flow rate is low - only 11 liters. Therefore, it is impossible to open the tap, for example, in the kitchen while the shower is running without the risk of burning the bather. But you can buy a gas water heater for a low price, and it works with low water pressure of only 0.1 Bar.

This is a reliable and safe geyser, one of the best on the market. It is equipped with a piezo ignition system with a constantly burning wick and automatic maintenance of the temperature set at the outlet, and has the entire necessary set of safety sensors. Works even at low pressure in the water supply network (only 0.1 Bar). In addition, this device is actually the only one on the market that protects against back draft, making it ideal for apartments with poor ventilation and poor smoke removal. Disadvantages - expensive spare parts and low flow rate - 10 l/min.

In terms of price/quality ratio, the water heater is one of the best. It is problematic to buy a geyser with similar characteristics at the same price, but the device is characterized by high reliability and ease of control with one handle to set the temperature. The column has high productivity (14 l/min, 28 kW), automatic electric ignition and hydraulic adjustment of the flame on the burner depending on the value of the inlet water pressure. That is, the temperature of the column does not change due to changes in water pressure in the network.

A gas water heater is a technique used to heat water in private homes and apartments. For this she uses natural gas, therefore it is the cheapest (in terms of operation), and therefore the most popular device in this category household appliances. When purchasing such devices, buyers are often interested in which geyser is better. To answer this question, you need to know possible options choices and their features, and then decide on your priority parameters.

Types of gas water heaters

Some buyers often confuse gas water heaters with heating boilers. These are different things. The first ones are used for heating water for washing dishes or bathing, and the second - for the purpose of heating the home.

The principle of operation of a geyser is simple - the incoming gas burns and releases heat, which is sent to the heat exchanger, heating it. This assembly is usually made of copper or other materials with high thermal conductivity. And a coil made of the same material is twisted around it to heat up from the temperature of the heat exchanger. Cold water enters the coil and, passing through it, gradually heats up, and then goes to the tap, being already hot at the exit. As for the resulting combustion products, they enter the chimney and leave the room.

Modern geysers are divided into types according to the following criteria:

• by place of production - abroad or in Russia;
• by type of ignition: manual, automatic or semi-automatic;
• by power: low, medium and high;
• by type of control: mechanical or with flame modulation;
• by type of combustion chamber: open or closed;
• by performance: heating hot water from 5 to 25 liters per minute;
• by the number of water intake points: one or two.

Thus, there are many flow household speakers, therefore, you should carefully choose a reliable and high-quality device for your home, taking into account whole line selection criteria.

Column selection criteria

Before purchasing a speaker for a private home or for a Khrushchev building, you need to decide how the equipment will be used. To do this, it is worth considering how many points you need to supply water to, what power is needed, the type of ignition and other factors.

Power

Gas water heaters are distinguished low, medium and high power. In the first case, the devices (from 9 to 20 kW) are designed to heat water for only one point. Columns of the second type (from 20 to 24 kW) make it possible to use two points at once, but for one of them the water pressure will be significantly weaker. Whereas equipment with high power (over 25 kW) is capable of supplying hot water with the same intensity to 2 points, or to 3, but with different pressure.

Advice! For a one-room apartment with one or two residents, a low-power device is sufficient. For a family of 3 people, it is better to choose a medium-power device. If there are several roommates in the house (from 4) or more than one bathroom, then you should pay attention to equipment with high power.

Arson

According to the type of ignition, geysers are divided into manual, semi-automatic (with piezo ignition) or automatic. The first ones are considered obsolete and are practically not produced today. To light them, you need to light the pilot light with a match, and then turn the knob to supply gas and ignite the burner. In semi-automatic dispensers, to ignite the gas supplied to the igniter, you need to press a button to generate a spark, and then open its supply to the burner.

Advice! During the day, the igniter of a semi-automatic water heater can be left unextinguished, which means that to heat the water you only need to open the gas supply to the burner.

IN automatic speakers Batteries are used for ignition, and the burner is ignited by turning the handle of the hot water tap. Manual and semi-automatic speakers are cheaper, but they need to be hung in a way that allows easy access to the device. In addition, devices with piezo ignition constantly consume small amounts of gas. Automatic gas water heaters operate completely independently, they do not require access, and there is no need for a constant ignition of the igniter.

When choosing a geyser, you should pay attention to such an important characteristic as setting the water temperature, which depends on the intensity of the flame and allows you to set and maintain the selected temperature regime. There are three types of adjustment:

• stepped, in which three modes are available: low, medium and high temperature;
• smooth, in which case the regulator gradually switches the settings from the minimum value to the maximum;
• automatic, in which the device independently determines the temperature thanks to electronic sensors.

Water pressure

In addition to external regulation, the final temperature is also affected by the water pressure. If it goes up or down, the temperature will change. In cases where the burner power does not change, you will need to set the degree of water heating manually, and this causes certain inconvenience.

Advice! When choosing, it is better to choose a column whose burner has modulating power. It independently adapts to changing pressure and maintains the set water temperature.

Depending on the exhaust system and methods for removing combustion products, water heaters are turbocharged or with chimney outlet. The former remove smoke and burnt particles out through a hole in the wall, and the latter into a common chimney. Based on this criterion, everyone determines for themselves the preferred output method, based on the planned location of the column.

Safety

In addition to the criteria listed above, it is worth paying attention to the presence of security sensors. These include:

• combustion and ionization sensors - if the flame goes out, they shut off the gas supply;
• draft sensor - detects its presence, and if there is no draft, or carbon monoxide goes back into the room, then the flow of gas is blocked;
• hydraulic valve - turns off overheated equipment;
• flow sensor - when the tap is opened, it turns on the column, and when closed it performs the opposite action;
• safety valve - is responsible for protecting pipes from ruptures when water pressure increases;
• pressure reduction sensor - in the absence of water or low pressure, this element blocks the start of the column;
• gas supply sensor - stops the operation of the water heater if there is no gas.

Important! When choosing a geyser, you need to make sure that all the listed sensors are installed in it, otherwise its use is very dangerous for humans.

Quality Rating

When purchasing a geyser for a home or apartment, it is worth studying reviews from experts, which may also be in the form of videos with reviews of models. You can find such information on specialized forums. According to the reliability and quality rating in 2017 and 2018, the best equipment is considered to be produced by Neva, Electrolux, Mora, Zanussi, Vaillant, Bosch, Ariston, which can be purchased in Leroy or in any specialized stores.

Please advise which gas water heater is better to choose? This question is often asked by those who need hot water supply, for example, in a country house or in a private house, or even in an apartment, but do not want to overpay. What aspects should you pay attention to when purchasing a geyser? How to choose this device and how does it generally work? Let's try to figure it out in detail.

You should refer to the reviews of experts, look at the rating best models for 2016-2017 and then it’s not difficult to choose best option device specifically for a specific budget and interior.

Experts believe that you need to choose a geyser based on several characteristics:

• Power;
• Brand;
• Ignition type;
• Presence of a chimney;
• Price.

Reviews from experts say that it is better to choose an automatic geyser from trusted manufacturers. Be sure to pay attention to the material used to decorate the geyser inside and outside, as well as the presence of a chimney. This factor will indicate whether the speaker can be placed inside the apartment.

To buy the ideal boiler for your home and budget, you should familiarize yourself with the following characteristics that will help you navigate your choice. The most important factor in the operation of a geyser is the power of the equipment. This is what determines the volume of water that the column can warm over a certain period of time.

Modern gas heating columns with a modulating burner are divided into types, and vary in power:

• Low-power (up to 20 kilowatts);
• Medium-power (from 21 to 24 kilowatts);
• High-power (25-30 kilowatts).

If you do not plan to heat a large amount of water, then one low-power column will be enough. Otherwise, pay attention to medium- and high-power units to draw water from several points at the same time.

Another important criterion when choosing a water heater is the type of ignition. Now there are few models left that require ignition with matches or a lighter. Such heaters are already outdated; it is necessary to pay attention to new and modern columns that have an automatic ignition system. It is produced using batteries or turbines; the wick is directly ignited when hot water is used. That is, for the system to start working, you only need to start using water, that is, open the tap. This type of speaker is safe during operation and is also much more convenient than older models.

There is also a type of ignition called piezo ignition. It is currently gaining popularity, but it can be noted that this is not the most convenient method. In this case, ignition is carried out by pressing a button, but it is not always possible to successfully install it so that the button is in a convenient place.

Also, due to this type of ignition, the gas water heater consumes more gas.

The type of burner will help you choose the best option. For example, if the burner has a constant power, then it will require manual adjustment. This is not the most The best decision, because the pressure is uneven and changes frequently. It is much better if the device has modulating burner power, then the jet will independently adjust to the pressure, and the water temperature will always be optimal.

Safety is an important factor; now almost all high-quality water heaters have three-stage protection, as well as overheating fuses. There must be a lock if the flame goes out. You should also be aware of the presence of a chimney. If the dispenser is turbocharged, then everything that burns is thrown out into the street, but if there is a chimney, then all waste is removed through it.

Instructions: how to choose a gas water heater for an apartment

There are a wide variety of flow columns available today. All types of Turkish production and Belarusian with automatic modulation, the Chinese manufacturer is very popular because of the prices.

The ratings of specialists and users will help you choose good household water heating appliance brands:

1. Vector JSD-20W is a Chinese water heater with electric ignition. In Russia, this high-quality water heating machine costs 8,000 rubles. There is a temperature sensor, this small compact water heater is ideal for small apartments with weak pressure.
2. Termaxi JSD 20-W - its functionality is much more modern, it has piezo ignition and a display good quality, copper pipe. The water temperature is also conveniently regulated. Price 6500 rub.
3. Zanussi GWH 10 Fonte - this column uses electronic ignition, a display, a copper heat exchanger, and a temperature controller. According to reviews, this is the best ratio of cost and quality, the price of such a unit is only 5,300 rubles.
4. Domestic, but not old Soviet manufacturers, for example, Neva or Iskra, also make high-quality heaters that use gas. Neva 4510-M costs 7,000 rubles, has two-stage flame modulation, and good safety control. It may be noted that this good heater at an affordable price.
5. Mora Vega 10 - completes the top of the best geysers. This is an expensive device, its price reaches 18,000 rubles, but its service life is long. During operation, not a single Chinese element is used, the assembly is exclusively European. This model has high strength, safety, and maximum efficiency with a copper heat exchanger.

It can be noted that the top contains both already well-known brands of water heaters and newcomers. Don’t be afraid of Chinese manufacturers; now they are not inferior to the “old guys” on the market and make really high-quality equipment.

At the same time, they are quite cheap, and in terms of quality they are almost equal to European companies.

If we choose German, Italian models, as well as from a Russian manufacturer, then they all differ in quality and reliability. Each gas heater made in China or Turkish versions has different performance and sizes.

Selecting a geyser by design

When choosing, pay attention to the above factors, and the column will last a long time without interruption. But you need to choose a gas water heater for an apartment based on whether there is a chimney. After all, almost all geysers can be easily installed in an apartment. The chimney goes to the roof of the house, that is, all waste generated during the combustion process is removed through the pipe. It is not possible to install a chimney in apartments, so such speakers are not suitable for installation in modern houses. Popular turbine dispensers remove waste using fan pressure. The exhaust enters a pipe that is attached to the column and is discharged outside through a special hole in the wall.

Speakers with a turbine are more expensive and depend on electricity.

These are the types of geysers that can be installed in apartments. To ensure that choosing a gas water heater does not present any difficulties, you should first understand how this device works. So, a gas water heater (boiler) is a wall-mounted heater that performs the function of quickly heating water by burning gas. Currently, there is a huge range of different heaters with different functions. They are practically no different from Soviet models, except that the design has become more modern and the functionality is simpler and more convenient.

Design modern model as follows:

• Pipes that supply gas and water;
• Burners;
• Heat exchanger.

When a hot water tap opens, the gas valve is activated. Gas enters the burner, this ensures the generation of heat and heating of water, as well as its supply through pipes. Air enters through a special hole. When the water flow stops, the gas supply stops.

Semi-automatic gas water heater and automatic machine

Currently, there are different geysers on the water heater market; they differ in their method of heating water. The automatic version runs on batteries; in fact, you just need to turn on the water and the heater will work on its own.

Nuances:

1. On the display of such models you can adjust the gas supply, as well as the water pressure.
2. If the model is semi-automatic, you need to light the wick every time, the automatic model does not require this, which makes operation much easier.
3. U automatic machine There is no button for the gas to start heating up, but a semi-automatic machine implies this.

In principle, after lighting the wick in a semi-automatic machine, it is no different from an automatic machine. Therefore, you should not be afraid of semi-automatic models; they cost a little less, and in operation they are practically no different from automatic ones.

Modern geysers: advantages

Gas water heaters have been popular for several years; even in Soviet times, many people used them to provide their home with hot water. They have various advantages as easy to operate.

Old-style devices are quite difficult to operate, because:

• You need to light the fuse every time;
• Adjust the temperature;
• Regulating the pressure, in general, is a long and complex process.

Modern models are much more convenient; automatic heaters work immediately after opening the water tap. Heating water using a gas water heater is much more profitable in terms of budget. Gas is only used when hot water is required, while the boiler uses additional energy to keep the water hot.

A geyser works much faster and can provide hot water to not one, but many points. It is also small in size, which allows it to be placed in any room.

With proper operation, the geyser will last at least 10 years. On average, models are in use for 15-17 years.

Modern speakers equipped with reliable overheating control systems. Based on the above factors, a geyser is the optimal solution for those who need to supply large quantity hot water.

How to choose a gas water heater for a private home: review

Choosing a geyser for a private home is quite simple, because you can purchase both models with a chimney and those without. So, you need to choose the right gas water heater for your home based on certain factors.

Namely:

1. Is there sufficient protection against overheating or gas supply without flame? In a private home, you need to pay special attention to the safety factor.
2. Protection against overheating of the model; there must be a fuse that will turn off the column if the heat exchanger approaches the boiling point.
3. Please note that there is a chimney that will help dispose of waste from heating water. In a private home, you can purchase models that include a chimney on the roof.
4. Be sure to look at the power of the device, as well as the material from which the heat exchanger is made.

It is imperative to look at the water heater’s passport to assess the safety of the device and its power.

Types of geysers (video)

In conclusion, it can be noted that a geyser is the best option for a water heater for those who have small room, but there is a need for hot water supply. Modern boilers are very simple and easy to use, but at the same time they are more reliable than old boilers and can last for several decades. The cost of water heaters is affordable, considering long term their work, and due to its compact size, even the smallest room will allow you to install this unit. The insulation makes these models silent, their design, and the display on some models, makes the speakers perfect for any bathroom or kitchen interior.
