The best geyser with piezo ignition for an apartment. How to choose a gas water heater: characteristics of water heaters for an apartment

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 are usually divided into two large classes:

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;
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 would also be useful for this type of speaker in an apartment to have an additional filtration system for tap water, i.e. . The hydrogenerator operates under 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:

Columns 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.
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 made by turning the gas tap handle. 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 you need to buy a water 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 of the instantaneous water heater, for which purpose measurements are taken of the installation site. 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 homes, the minimum water pressure at which the water heater can turn on will be of great importance. 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 descriptions of the 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 geyser is a water heating device, usually a flow-through type, that uses gas to heat water. When an apartment building is 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 to prepare hot water, and in old two-story houses they can be used to maintain the temperature of the coolant.

Instantaneous gas water heaters can usually be found in older homes. Homeowners in multi-storey buildings with centralized hot water supply are practically unfamiliar with this unit. But the inhabitants of Khrushchev buildings quite actively use these devices.

An instantaneous gas water heater, or in simple words a gas water heater, is a unit for preparing household 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, a water heater of this type is quite convenient - when you open it, 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:

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

Gorenje GWH 10 NNBW - price up to 20,000 rub.
Beretta Idrabagno Aqua 14i - price up to 25,000 rub.
Bosch WRD 13-2G - price up to 22,000 rubles.
Mora Vega 13 - cost up to 20,000 rubles.
Ariston Fast Evo 11C - price up to RUB 13,060.
Zanussi GWH 10 - cost up to 12,000 rubles.
Electrolux GWH 265 ERN Nano Plus – price up to RUB 10,000.
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 have an original design, but 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.

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.
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.
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:

chimney - the most optimal choice when the corrugated sleeve 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 equipped 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 the key points when choosing a device is the free 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:

For a single person living with a single pet, a dispenser with a capacity of 10 l/min is suitable. and less.
A couple with a baby or pet can get by with a 9 l/min dispenser.
A family of three people and a pet or four people, two of whom are children – up to 15 l/min.
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.

A device with low power can supply hot water to only one point in the house, for example, a 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. The 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 what 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 to automatically turn on the gas water heater when the hot water tap opens and turns it 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;
low water pressure sensor - 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 to install gas equipment, for example, a stove, installing a water heater 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:

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

After which the specialists cut into the 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 does not need to be installed, but it can be used to monitor the operation of gas devices. It monitors the level of propane in the air and, if detected, signals this.

The water heater cannot be installed on a load-bearing wall of a 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 installing pipes yourself, you must follow the following rules:

Before starting work, turn off the gas.
Work must be carried out with open windows.
Debris that appears in the pipes during installation must be removed.
Pipes cannot be routed through windows and doors.
It is prohibited to use the ventilation shaft for laying pipes.
The gas pipeline should not be installed in a wall.
The use of thin flexible hoses longer than 3 meters is prohibited.
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.

It is difficult to imagine a modern person’s house or apartment without hot water. However, many houses do not have central hot water supply. This problem can be solved with the help of a water heating agent, which can easily run on gas.

Device and purpose

The geyser is the most famous device on the heating equipment market, which provides any type of living space with hot water. In the modern world there are a large number of water heating devices, but no one has yet been able to replace the gas water heater. This can be explained by several factors:

a geyser is characterized by great savings, as it can provide hot water supply to several hot water intake points located in a house or apartment;
A geyser allows you to use hot water at any time and in unlimited quantities.

Geysers consist of a huge number of elements:

main burner, the best material for which is steel;
a system of pipes necessary for water circulation;
the heat exchanger can be made of either steel or copper;
a housing that not only regulates the amount, but also controls the flow of water;
ignition unit, which directly depends on the power supply;

a control unit with which you can monitor the parameters responsible for the normal functioning of the column;
pipes necessary for the water to be supplied, gas and hot water discharge;
membrane gas valve;
a safety system that is necessary if there is no water, the pressure changes, the dispenser overheats, or other situations that may lead to accidents;
combustion product removal unit.

It should be noted that geysers are water heating devices that heat water instantly. Water enters the column through the incoming pipe. Next, the water flows through a pipe system, which is influenced by the heat emanating from the heating equipment. As water moves through the pipe system, its temperature increases. This entails supplying hot water from the flue pipe to the tap.

Ignition of the main burner in various models of modern columns can be carried out using different elements.

Using a piezoelectric element. To light the speaker using this method, you need to press a certain button. The pilot light inside the column is constantly lit, turning it off will turn off the entire column.

Using batteries, providing the electric spark necessary to ignite the burner. If the device does not work, gas is not consumed. Batteries are a very convenient tool as they can last up to 1 year.

Using a hydraulic turbine, which causes the spark needed to ignite the burner. The hydraulic turbine starts working only when the column is turned on. However, such models are very sensitive to low water pressure.

What to consider when choosing?

When choosing a gas water heater, it is necessary to take into account a number of basic characteristics, heating equipment must have:

power;
ignition type;
burner type;
type of combustion products removal;
safety.

Power is one of the most important characteristics that must be taken into account when choosing heating equipment. Power determines the overall performance of the equipment. In other words, it sets the amount of water that the geyser can handle in a certain time interval. The geyser is designed for power from 6 to 32 kW. It is worth noting that the power of an electric water heater ranges from 1.5 to 3 kW.

Therefore, depending on the number of kW, power is divided into three types:

small (from 6 to 19 kW);
medium (from 20 to 28 kW);
high (from 29 to 32 kW).

For a private house with several water intake points, the best option is a gas water heater with medium and high power.

The type of ignition is also an important characteristic that can influence the purchasing decision. If previously, matches and lighters were used to light the device, now modern models offer an improved ignition system. There are two types of systems: semi-automatic and automatic.

On the one hand, the semi-automatic type of dispensers entails significant gas consumption. This is due to the fact that the wick cannot be turned off. To turn it on, you need to press the piezo ignition button. On the other hand, the automatic type of dispenser not only reduces gas consumption, but also starts up extremely simply. To start such a system, you need to open the hot water tap.

You should not lose attention to the type of burner, which comes in two types: with constant power and with regulating power. It is inconvenient to use burners with constant power, since you will have to adjust it yourself. This can be explained by the fact that the water pressure is constantly changing and entails a change in temperature. Consequently, temperature-simulating burners successfully cope with this problem. They independently adapt to changing pressure.

The type of exhaust of combustion products is not a fundamental characteristic that has a significant impact on the choice of equipment. However, it is recommended to study this characteristic in order to make the right choice. There are two types: chimney and turbocharged. On the one hand, a chimney column is needed only in one case: if the tubular channel can be routed into an existing chimney. On the other hand, turbocharged devices are not popular, as there is a risk of freezing if the temperature outside is below freezing.

The key issue is safety. Speakers must be equipped with several levels of protection. For example, modern speakers have three levels of protection. Each of them is necessary for different unforeseen situations. Therefore, you need to pay attention to the presence of protective sensors, since high product safety is a guarantee of reliability and quality.

However, there are factors that have a secondary influence on the decision to purchase an electric water heater:

size;
form.

The size of the geyser does not matter much, but it is necessary to take this factor into account. The size of the column is determined by the scale of the room. If the room allows you to install a large speaker, then choose the appropriate size.

If you want to hide a boiler in an apartment using a kitchen unit, then choose a compact form.

A gas water heater is a dangerous device, since its operation requires the use of flammable fuel. Therefore, during the installation process, care must be taken to avoid its leakage in the future.

In order for a geyser to serve for a long time, it is necessary to follow certain rules and recommendations for using gas water heaters:

they are recommended to be installed in a place where there is ventilation;
Do not install the device near flammable objects;
if the chimney is clogged, you need to call a technician as soon as possible who can fix the problem;
Great attention should be paid to the operation of the geyser, because its overheating can negatively affect its service life.

The gas water heater is the most popular among all water heating devices.

Main advantages:

Economical to use. The heated water is used immediately, there is no need to maintain the temperature for a long time.
Beautiful appearance devices and compact dimensions compared to electric heaters.
Reliability, durability and safety. High-quality geysers can delight you with uninterrupted operation for many years.

Currently, all new buildings are equipped with centralized hot water, however, residents of individual houses and Khrushchev-era buildings continue to actively use boilers. Gas water heaters are one of the most economical devices that can provide hot water to several water points 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 allows you 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:

Protective housing to prevent damage to necessary components and elements.
Modulating burner which performs the function of heating water.
Heat exchanger.
Automation.

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

Power.
Performance.
Type of ignition.
Burner type.
Additional functions.

The performance of the system depends on the power of the gas water heater.

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

Up to 19 kW serves 1 water collection point (small).
From 20 to 28 kW The power is enough for 2 points (medium).
Over 28 kW can serve DHW from 3 or more points (high).

When choosing, you need to determine the volume 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 taps at the same time. You need a powerful unit with maximum hot water supply.

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 a water heater is its performance. In most cases, it is measured in l/m. When choosing a column with a total capacity of 10 l/min, the device is capable of passing 10 l of water when heated with a temperature increase of 10 C to 35 C.

You can calculate the water flow level 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, geysers were lit with matches. Modern equipment works differently, they include:

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.
Semi-automatic method– to ignite the igniter, you must press a special button, which turns on the piezoelectric element. 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.
HydroPower system– the device is turned on due to an electric discharge generated by the built-in hydraulic turbine. To operate, you need a flow of water with sufficient pressure and gas.

Automatic water dispensers are comfortable and economical; they do not have a standby wick, and gas is used only when the water is turned on. That's why they are the most expensive.

The type of burner also serves an important function.

There are 2 types: constant and variable power:

In inexpensive water heaters Continuous power burners are installed. They are inconvenient because the water temperature must be adjusted manually.
Columns with burner transition power and are the best. When using such equipment, power adjustment is made automatically depending on the water pressure.

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

When choosing a water heater, you need to clarify additional nuances:

Dimensions of inlet and outlet pipes.
In the gas supply system availability of the required amount of gas.
Maximum permissible water pressure.

The main thing is safety

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

The most necessary of them:

If gas supply failure occurs– instant automatic shutdown (ionization sensor).
Flame sensor– a safety device in case of failure of the ionization sensor.
Temperature setting function protects the device from rupture.
If there is no draft in the chimney, the device does not turn on, thereby neutralizing carbon monoxide poisoning.
Flow sensor turns on the column when using a hot water tap and turns off when closing.
Thanks to the low pressure sensor, the column does not turn on if the water pressure is less than prescribed.
If the water pressure is high, the heat exchanger is protected by a relief safety valve.

If a gas water heater lacks at least 1 of the above sensors, it cannot be called safe for 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

Selecting a geyser- not an easy task. There are a large number of 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 popular are:

Neva 4510

Created using domestic and imported components. Works both from a centralized water supply system and from a source of liquefied gas. Thanks to this, it can be installed in country houses where gas cylinders are used.

Maximum heating is 25C when the flow rate is 10 l/min.

Ariston

Water heater with piezoelectric or electric ignition type. Excellent Italian quality with a reliable security system, for reasonable money. At a flow rate of 11 l/min, heating to 25 C.

Termaxi

Chinese geysers of good quality. The advantage is the modulation burner. Among them there is a device model for 12 l/min, which allows you to connect 3 hot water taps.
