Inexpensive and reliable gas column. Choosing a geyser for heating water

If it so happened that there is no hot water supply in your house, but there is gas, then you need a geyser to heat water. Specialists of "Expert Price" analyzed the models of geysers that buyers were most interested in at the beginning of 2019, and chose the 15 best ones. Now you will learn about them. But first, let's choose a manufacturer.

Which company's gas water heater is better?

The leading positions in terms of popularity, reliability and build quality today are occupied by gas water heaters from the Czech manufacturer Mora Top. His products never lie in stores for a long time, and therefore sometimes you just need to have time to place an order. Among foreign manufacturers of gas water heaters, the always in demand brands Bosch and Ariston are not far behind. Products with a good price-quality ratio are offered on the Russian market by Zanussi and Hyundai. The best domestic manufacturers are traditionally represented by gas water heaters of the Neva and Ladogaz brands.

Useful tips to ensure long and reliable operation of gas water heaters

1. Installation and connection must be carried out by qualified personnel. Often, the quality of its work depends on how the geyser is set up.
2. It is necessary to regularly clean the igniter and heat exchanger from combustion products (it is strange to blame the column for blockages). This will significantly extend the "life" of the device.
3. In old houses with too low water pressure in the system, it is better to install special pumps. With a stable water pressure, automatic start-up occurs without problems, and the heating temperature will be maintained more correctly.
4. It is necessary to follow the important recommendations from the manufacturer, indicated in the user manual.

Right choose a column model depending on the required or desired amount of hot water. In principle, structurally modern gas instantaneous water heaters can only conditionally be divided into versions for one, two or more points of water intake. It's more about the declared maximum performance. A simple rule: less than 12-13 l / min - one tap or alternate use, more - enough for two or more.

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

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

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

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

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

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

Finally, in the matter of reliability of work, it is worth paying attention to safety. Modern models of geysers are equipped with three levels of protection, which manifests itself in various incidents - an accidental cessation of the flame, the sudden appearance of reverse thrust. Special hydraulic valves are also provided to help avoid overheating.

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

Analysis of popular gas water heaters

Experts in the field of such equipment have already compiled a rating of gas water heaters. The opinion of experts formed the basis of the review, which presents the top 5 best brands specializing in their manufacture.

1 seat for Bosch WR 10-2P

The undoubted leader of the review is the Bosch WR 10-2P model. It attracted ordinary users with its stylish design and compact size. The unit will harmoniously fit even into a small room. Experts unanimously recognize it mostreliable: The automatic ignition system is used. The device itself is activated when the hot water tap is opened. The limitation on the heating temperature is also thought out. Ignition is carried out using a piezo - batteries will not be needed.

Column Bosch WR 10-2P

With such a technique, you should not worry about pressure - it will work even if it does not differ in stable pressure. By the way, you can regulate the flame and the temperature of the liquid using special regulators.

However, such “perfection” also has small drawbacks.

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

2nd place for Ariston Fast Evo 11C

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

One of the main advantages is network operation, which is better than the option with batteries that can sit down at any time. The heating power of 19 kW will provide a productivity of 11 liters per minute of working time.

Column Ariston Fast Evo 11C

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

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

This, no doubt, can be called the Neva Lux 5514 option - this option may well compete in build quality with expensive foreign offers. Of course, the functionality here is not as chic as that of well-known brands, but in general, the model is impressive:

• auto ignition;
• intuitive control;
• independence from water pressure (can be adjusted using hydraulic adjustment);
• the body does not heat up during operation;
• can work with two points of water intake(there will be no temperature fluctuations);
• there is a gas control;
• the combustion chamber is cooled by a water system.

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

Column Neva Lux 5514

The following disadvantages prevent the rise of positions in the top:

• noticeable noise during operation;
• battery replacement;
• expensive in case of heat exchanger.

Advantages and disadvantages of Mora Vega 10 in 4th place

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

• European build quality (manufacturers promise that there is not a single detail from China in the design);
• copper heat exchanger (increases efficiency up to 92.5%);
• scale-free technology in pipes;
• a full range of security systems (does not start without turning on the water, protection against overheating, against the appearance of reverse thrust, the presence of fuses for the functioning of the burners).

Column Mora Vega 10

Unlike competitors, Mora Top has a more tangible weight - at least 2.5 kg. However, there is a drawback: with a weak water pressure, the device may simply not turn on (the manufacturer has calculated at least 0.2 bar).

5th place for Zanussi GWH 10 Fonte

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

Column Zanussi GWH 10 Fonte

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

Among others not included in the list, but no less worthy representatives are Vaillant, Electrolux, Termaxi, Beretta, Vector.

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

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

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

Coping with seasonal shutdowns of hot water supply is not a problem today, as there is a huge range of water heating equipment on the market. The most efficient are gas water heaters. Since gas is cheaper than electricity, they are also more economical to run. Which geyser is suitable for a private house? Read our article.

The principle of operation of the device

To make the right choice, you need to understand and. It is also called a flow heater.

Two tubes are connected to the body. One supplies gas, the other supplies water. When water is supplied to the line, pressure arises that acts on the membrane. It bends and opens the gas valve. The burner fires and heats the water, which passes through the heat exchanger coil. The flow exits when the mixer is opened.

In order to choose the right device for the cottage or home, it is necessary to take into account the parameters of the equipment and the condition of the water supply line. The correct setting of the device will depend on the pressure in the system. read the previous article.

What technique to choose

What should be considered to make the right purchase? First of all, the features of the room: its area, ventilation, the possibility of organizing a chimney. Then pay attention to the features of the technique:

• Power and performance. What pressure is the equipment designed for;
• Ignition type;
• Case dimensions;
• The combustion chamber;
• The quality of the heat exchanger;
• Work safety;
• Control;
• Price.

Performance and Power

The passport indicates the rated power of the device. The higher it is, the larger the displacement can be heated. So:

• 17 kW refers to low power;
• 22-24 kW - to the average;
• 28-31 kW - to high.

Important! Don't forget to consider the quality of the wiring in your home. If it is old, then replace it. Or choose a low-power technique.

To provide one sampling point, heating of 10 liters per minute is enough. This is quite enough for two people. For a shower and sink split and used by three people, 13-14 liters per minute will do. A large family will need 15-16 liters. In this case, you can connect all the necessary points.

It is important that there is enough pressure in the line to trigger a powerful column. Otherwise, it will not turn on or it will give out bad pressure. If you do not have a central water supply, but a well, you can install a circulation pump. For low pressure and small, weak water pressure, a pump is a great option.

Dimensions and type of ignition

How to choose a product by dimensions? To get started, select an installation location. Then you will understand what size the technique should be. In general, gas heaters are light and compact because they do not have a storage tank.

Selection by type of ignition begins with an inspection of the room, checking for the presence of a chimney or ventilation in it. Manufacturers no longer produce products with manual ignition of the wick. Today the following types are popular:

• Piezo ignition. The wick ignition system is automatic, but to start it, you need to press the piezo ignition button and hold it for at least 10 seconds. Model Data cheaper than others.
• Electric ignition. Batteries are located in a special compartment of the case. They are triggered at the moment the mixer is opened, striking a spark for the burner. All you need to do is change the batteries periodically.

• Ignition with a hydro turbine. Due to the water pressure in the housing, a turbine is rotated, which generates current for the spark. Ignition depends on the presence of pressure in the system. This is the most expensive type of speakers.

Type of combustion chamber

There are two types of combustion chambers:

• open. Requires a chimney. The fuel, together with oxygen, burns out indoors, and then the combustion products are removed through the chimney.
• Closed. A coaxial pipe is used. The best option for installation in a private house: the device does not burn fuel inside. Oxygen enters the chamber through the outer channel, and combustion products are removed through the inner channel. For this, the pipe is brought out into the street.

The disadvantage of closed chambers is that the built-in fan is powered by electricity. It follows from this: if the electricity is turned off, then there will be no hot water supply.

Heat exchanger material

The radiator or heat exchanger is an important part. Water passes through its coil for heating. Since it is constantly in contact with liquid and subjected to heat, the quality of its manufacture is important.

The material can be brass, copper, steel. Copper is considered the most efficient, it has a high efficiency. However, impurities in its composition lead to burnout of the radiator. Read the article " » to learn more about it.

When choosing a technique, carefully inspect the radiator. Cunning manufacturers install used blocks in factories that have already been soldered.

Control

Mechanical control allows you to separately adjust the force of water pressure and gas supply. The electronic control sets the indicators more precisely, and the set parameters are reflected on the display:

• Temperature;
• The strength of the flame;
• Fault codes.

Safety at work

It is important to choose a safe technique that should protect the user when:

• Interruptions in the supply of gas and water;
• Fuel leakage;
• Lack of traction, overheating or high pressure.

To do this, the device has special sensors that, reacting to deviations in operation, turn it off:

• Flame control. There is an electrode near the burner. In the presence of a flame, it supplies current to the controller. As soon as the flame goes out, the current supply stops and the column turns off;
• Flame sensor. Control of the previous sensor. If the electrode does not work, the combustion sensor comes to the rescue;
• Protection against overpressure in the system. The safety valve releases liquid when the pressure exceeds the nominal values;
• Overheat sensor. If the heating temperature exceeds 100 degrees, the equipment will automatically stop working;
• Traction sensor. Weak draft is dangerous for carbon monoxide leakage into the room. To avoid this a sensor is installed that monitors the presence and absence of traction;
• Limit timer. Turns off the heater after 20-30 minutes of heating.

When choosing the best water heater, consider the presence of protective systems. Functionality is specified in the product data sheet.

Manufacturers and price

Much when choosing a column also depends on the manufacturer and the place of assembly. The most popular brands are:

• . Italian brand. The panels are equipped with a display and convenient control;

• . German production. The technique is characterized by high performance, the presence of a display and indication;

• produced by Bosch. It is possible to regulate the power by modulating the burner flame;

The geyser is the most popular among all water heaters.

Main advantages:

1. Economy in use. The heated water is used immediately, there is no need to maintain the temperature for a long time.
2. beautiful appearance devices and compact dimensions compared to electric heaters.
3. Reliability, durability and safety. High-quality geysers are able to please uninterrupted operation for many years.

Currently, all new buildings are equipped with centralized hot water, however, residents of individual houses and Khrushchevs continue to actively use boilers. Gas water heaters are one of the most economical devices that can provide hot water to several water points that are located in a residential building.

Modern speakers are very different from those used before, they have become the most convenient and productive. They have an adjustment function that makes it possible to lower or increase the temperature.

Most are equipped with a display for easy setup. For successful operation of the device, the outlet water temperature must be up to 60C.

How to choose a column?

The gas water heater consists of:

1. Protective housing to prevent damage to the necessary components and elements.
2. Modulating burner that performs the function of heating water.
3. Heat exchanger.
4. Automation.

To select a suitable gas column, you need to familiarize yourself with its technical capabilities:

1. Power.
2. Performance.
3. Ignition type.
4. Burner type.
5. Additional functions.

The performance of the system depends on the power of the gas column.

On average, its value varies from 17 to 30 kW and is divided into 3 types:

1. Up to 19 kW Serves 1 point of water intake (small).
2. 20 to 28 kW power is enough for 2 points (average).
3. Over 28 kW can serve domestic hot water from 3 or more outlets (high).

When choosing, you need to determine the amount of hot water used. If the apartment has 1 or 2 water supply points, the heater power may be minimal. When using 3 or more faucets at the same time. you need a powerful unit, with a maximum supply of hot water.

You should carefully read the instructions and make sure that these indicators are in the "Useful power" line. Not to be confused with power consumption!

The next important factor of the water heater is its performance. In most cases, it is measured in l/m. When choosing a column with a total capacity of 10l / min, the device is able to pass 10 liters of water when heated from 10C to 35C.

You can calculate the level of water flow based on the number of taps in the house. According to average data, 1 faucet in an apartment passes 7 liters of water in 1 minute. When using 1 mixer, you can order a water heater with a capacity of 10 l / m. If the consumer uses water from 2 taps at once, it is recommended to choose a device with a capacity of 13 l / m.

Previously, gas water heaters were lit with matches. Modern equipment works differently, there are:

1. Automatic method- when the water is turned on, the device starts working due to the appearance of a spark using electricity or a battery. When you stop using hot water, the device turns off.
2. Semi-automatic method- to ignite the igniter, it is necessary to press a special button, with which the piezoelectric element is turned on. When the water is turned on, the main burner lights up, when turned off, the burner goes out, the wick remains burning. Accordingly, this is an uneconomical option, since more gas is consumed.
3. Hydro power system- the device is switched on due to the electric discharge generated by the built-in hydraulic turbine. For operation, a stream of water with sufficient pressure and gas is required.

Automatic dispensers are comfortable and economical, they do not have an on-duty wick, gas is used only when the water is turned on. That is why they are the most expensive.

The type of burner also plays an important role.

There are 2 types: constant and variable power:

1. In inexpensive water heaters continuous burners installed. They are inconvenient in that the water temperature must be adjusted manually.
2. Columns with transient power burner and are the best. When using such equipment, power adjustment is performed automatically depending on the water pressure.

Recently, an improved model of a geyser using a modulating burner has appeared. It takes into account the temperature of the water entering the heater.

When choosing a water heater, it is necessary to clarify additional nuances:

1. Dimensions of incoming and outgoing pipes.
2. In the gas supply system the required amount of gas.
3. Maximum allowable water pressure.

The main thing is safety

The water and gas supply system often malfunctions, for this reason, the geyser is a high-risk device. The heaters are equipped with various protective sensors and relays. When buying, it is worth studying the availability of such devices.

The most necessary of them:

1. In the event of a gas supply failure– immediate automatic shutdown (ionization sensor).
2. Flame sensor- safety device, in case of failure of the ionization sensor.
3. Temperature setting function protects the device from breaking.
4. If there is no draft in the chimney, the appliance does not turn on, thereby neutralizing carbon monoxide poisoning.
5. flow sensor turns on the column when using a hot water tap and turns it off when closing.
6. With low pressure sensor, the column does not turn on if the water pressure is less than expected.
7. If the water pressure is high, the heat exchanger is protected by a safety relief valve.

If at least 1 of the above sensors is missing in the geyser, it cannot be called safe to use. An accident can happen at any time, so it is better to refuse such equipment, even if it is sold at a bargain price.

Manufacturer reputation

Choice of geyser is not an easy task. There are many heat exchangers on the market. To be sure of the quality and reliability of the device, it is better to give preference to well-known manufacturers.

The most requested are:

Neva 4510

Today, despite the active modernization of housing and communal systems, the problem of hot water supply remains relevant. During the season of repair and preventive maintenance at the CHP of residents of apartment buildings, we expect a massive shutdown of hot water.

The recurring need to heat water in a pile of pots on the stove or to plunge under the cold jets in the shower involuntarily makes you shiver. How to get out of the situation? An effective solution would be a geyser that performs the function of constant water heating. In this article, we have compiled for you an advanced rating of gas water heaters for an apartment for 2019-2020.

comparison table

If you have not yet decided which geyser for an apartment to choose from our rating, then you can compare all the models from the list using the table in which we have indicated the most important characteristics and their average price.

How to choose a good model for an apartment?

The most important criterion when choosing a model of a flowing geyser is its performance - the flow rate of liters of water per minute. The higher this indicator, the more efficient the water supply in the column will be. However, it is worth noting that a good geyser does not necessarily have to have maximum performance in the technical data sheet. Everything is directly proportional to several factors: the number of people living in the apartment, how many of them need to use hot water at the same time, as well as the number of mixers.

Another important criterion is thermal power. This indicator will help you figure out how many sources a gas water heater can provide with hot water at the same time. The minimum indicator is a mark of 17 kW - this type of water heater is able to ensure the operation of one mixer.

It is worth noting the criterion for the type of ignition of the gas column. The best option would be a water heater with electric or piezo ignition. They are automated and do not cause operational inconvenience to owners. To date, they are the most economical and modern, in contrast to the already out of circulation columns with a manual type of ignition.

The key factors when choosing a device can also be: weight, design, dimensions of the equipment, type of communications, equipment, a set of automated protective functions and, of course, the average price of the column. Together, all these indicators should correspond to a certain type of use - it is best to consult with the seller of the intended place of purchase to determine the optimal model of the water heater.

How to install and connect correctly?

Improper installation or installation of the gas unit can be a serious threat to the life and health of the user. To avoid such consequences, it is worth following a certain procedure. After purchasing gas equipment, in order to register it and confirm the possibility of installing it indoors, you must:

1. Write an application to the gas distribution company.
2. Get a plan from BTI or Rosreestr.
3. Provide an extract from Rosreestr confirming ownership.
4. Contact the relevant organization to draw up a project.
5. Find certified specialists from an organization that has a permit for gas work.

It is very risky to engage in communications and installation of the column yourself. The best way out is to call the wizard, who will qualitatively connect the device, help to understand the intricacies of its use.

In addition, incorrect or unauthorized installation of a gas water heater is punishable by significant fines, not to mention the fact that due to the threat created, people's lives can be in danger.

Entrust the work to professionals, asking in detail about all the nuances of his work, in order to further protect yourself and people close to you.
