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 is not difficult to choose the optimal version of the 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 The operation of a gas water heater 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 Such heaters are already outdated; it is necessary to pay attention to new and modern speakers that have an automatic ignition system.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 it is not the most convenient way. 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 geyser This type of ignition 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 best solution, 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.
Security is an important factor, now almost everything quality water heaters They 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
Currently there are a variety of flow columns. 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:
- 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.
- 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.
- Zanussi GWH 10 Fonte - this column uses electronic ignition, a display, a copper heat exchanger, and a temperature controller. According to reviews, this best ratio cost and quality, the price of such a unit is only 5,300 rubles.
- 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.
- 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, maximum efficiency with a copper heat exchanger.
It can be noted that the top contains both famous brands water heaters and beginners alike. 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 boiler made in China or Turkish options, 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 various 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.

The design of the modern model is as follows:
- Pipes that supply gas and water;
- Burners;
- Heat exchanger.
When the tap opens hot water, 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:
- On the display of such models you can adjust the gas supply, as well as the water pressure.
- If the model is semi-automatic, you need to light the wick each time, automatic model this is not required, which greatly simplifies operation.
- An automatic machine does not have a button for the gas to start heating up, but a semi-automatic machine does.
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, back in Soviet era Many people used them to provide hot water to their homes. 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 gas water heater works much faster and can provide hot water to not one, but many points. It's also different small in size, which allows you to place it in any room.
At correct operation, the geyser will last at least 10 years. On average, models are in use for 15-17 years.
Modern speakers are equipped with reliable overheating control systems. Based on the above factors, the geyser is optimal solution for those who need a feed 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:
- 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.
- 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.
- 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.
- 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, given their long service life, and due to their compact size, even the smallest room can 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.
If you really buy quality speaker, then hot water will be in the house constantly, also - this is enough economical solution, which can provide liquid supply 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:
- Beautiful design.
- Simple and convenient operation.
- Long term services.
- 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 meet such a “dinosaur” today, it is better to bypass it and make a choice in favor modern models. Now the column is working automatic system ignition, 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 hard to reach place, then it’s 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 provide normal temperature liquids.
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 draft occurs. 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 this, 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.

Geyser - instantaneous water heater working for natural gas. If you do not have hot water supply, but gas is supplied, this equipment will increase the comfort of your life. You simply open the tap, hot water flows out of it, and its temperature is regulated by you yourself. Even if you have a centralized supply of hot water in your house or apartment, but you are not satisfied with the price you have to pay for heating, or perhaps you are not satisfied with the temperature, installing a gas water heater will also solve these problems. Heating water costs much less than it is provided centrally - this results in significant savings on utility bills. To understand which geyser is better, you will have to study the structure of the equipment and its types. Then the choice for you will be simple and conscious.
The structure of the geyser
- gas burner device and gas removal system;
- heat exchanger;
- ignition and control module.
All these units have several modifications and their arrangement gives different models With different characteristics. All this allows you to choose a unit to suit your own requirements, because you can only say which geyser is better by being tied to a specific situation.
Type of ignition
For the dispenser to start working, you need to light the gas. Older models were lit manually by holding a burning match to the igniter. Today such units are no longer on sale; they are a thing of the past. They have been replaced by others that operate in automatic or semi-automatic mode.
Piezo ignition
In geysers with a piezoelectric element, ignition occurs in a semi-automatic mode. There are two burners - main and pilot. The pilot burner is a small wick that burns continuously, whether there is hot water flow or not. The main burner turns on only when the tap opens. The rest of the time it is turned off.
The procedure for starting a gas water heater with piezo ignition is simple: press the button located on the front panel, a spark appears on the candles, which ignites the pilot burner. When the hot water tap opens, gas is supplied to the main burner, ignition occurs from the pilot burner. While water is being consumed, both burners are lit. The tap was closed, the gas supply to the main one stopped, only the pilot one was on again.
Piezo ignition device for geysers - a simple and inexpensive device
What are the advantages of geysers with piezoelectric elements? These are the cheapest models and usually have mechanical control- a regulator that allows you to change the height of the flame, thereby regulating the temperature of the hot water. These models are non-volatile, which can be important for a summer residence.
There are more shortcomings and they are more serious. The wick burns (should burn) constantly while you are using the column, and this is gas consumption. Even if it is small, but constant, as a result, quite a decent amount accumulates in a month. So this is far from the most economical way heat the water. The second disadvantage is also associated with the burning of the wick. If it goes out, you will not be able to light the column. The wick goes out because it does not have enough oxygen to burn, or because it periodically occurs in the chimney. reverse thrust, which blows out the flame. Since there is a flame controller, this is not a big deal - the gas shuts off automatically, but having to light the pilot burner again is unpleasant.
Electric ignition
Automatic geysers have electric ignition. This is an electric spark generator that is activated when the tap is opened. The rest of the time the gas is not lit, which significantly saves fuel. There is an electric ignition powered by batteries, and there is one from a 220 V network. Which gas water heater is better for this parameter must be chosen depending on the circumstances.
If your lights go out frequently, it makes sense to choose a battery-powered model. As you understand, in this case you have to make sure that they don’t “sit down.” If there are no problems with electricity or there is a backup power source, it is better to choose a gas water heater operating from a 220 V network. Plug the cord into the outlet once and forget about it. Electricity consumption is negligible, so they have almost no impact on bills.
Gas water heaters have electronic control. A board with a microprocessor is installed in the case; the desired temperature is set from a small control panel (push-button or touch). A small liquid crystal screen is often installed here, which displays the current state of the equipment, the temperature of the water, if it is being heated. This type of geyser is the best if you value ease of use.
Disadvantages - more high price and power requirements. Electronics need a stable voltage of 220 V with small deviations of the order of 2 * 3 V. We cannot maintain such parameters, so in order for an automatic gas water heater to work for a long time, a stabilizer is required, and it is better not a relay, but an electronic one. It not only stabilizes the voltage, but also evens out the shape of the pulses, which is also very important for imported water heaters.
Burner, combustion chamber, chimney
Heating of water in a gas water heater occurs due to the heat released during gas combustion. The combustion itself occurs in the burner, and it is “packed” into the combustion chamber. Unburnt gases that remain in the chamber are discharged through the chimney. Let's take a closer look at all these devices.
Burner - main unit
Burner
The heat source in the gas column is gas burner. There are three types: single-stage, two-stage, modulated. The first two types in lately are almost never found - they do not allow maintaining the set temperature, so there is no point in considering them - all columns have a modulating burner.
Modulating burners can be controlled manually - with a special handle mounted on the body - or through a microprocessor that maintains a given water temperature. Burners are made mainly of galvanized steel, since this material is optimal for performing the assigned tasks. It is inexpensive, durable, has a high melting point, and can withstand frequent heating.
Types of combustion chamber and chimney
Combustion chambers in geysers are of two types - open and closed. Their name reflects the essence:
- closed (turbocharged, fan) is a metal box into which a burner is inserted with a socket at the top for installing a chimney;
- open (atmospheric) - this is actually the entire body of the column, since there is no isolated space, just a burner is installed in a certain place, on top there is a lid with a socket to which the chimney is connected.
For different types of combustion chamber it is necessary different chimney. IN open cell Air intake occurs from the room, therefore an effective ventilation system, normal air flow and an atmospheric chimney exiting into the ventilation duct are necessary. The closed chamber is equipped coaxial chimney(two pipes different diameters, inserted one into the other), which is led out through the wall to the street. In this case, combustion products are removed forcibly using a fan inner tube, and oxygen flows directly to the burner through the outside.
More stable at normal conditions the gas water heater is working with closed camera combustion, but it has disadvantages. In winter, the chimney can become overgrown with frost, causing the heater to go out (it is extinguished by an automatic system that controls the removal of combustion products). The second point is that with a strong side wind, the air flow can blow out the flame. The gas supply is turned off by the same automatic system, but the situation is unpleasant. The third circumstance is that not all city authorities allow holes in the walls of houses and the insertion of pipes.
So in this case, it is difficult to say exactly which geyser is better - it depends on many factors.
Heat exchanger
Water is heated while it flows through the heat exchanger. It represents metal pipe installed above the burner. The shape of the heat exchanger in a gas water heater is special - a pipe with fins is laid in a snake at the bottom, then a sheet of metal is installed around it, on top of which the pipe is wound in a spiral. Water flowing through this long path is heated by the heated metal.
Heat exchangers are made of galvanized steel (the most budget option), stainless steel and copper. The best in terms of efficient heat transfer are copper. They are the most economical, but also expensive. The most durable ones are stainless steel, but they are much worse at heat transfer. Which one in in this case a geyser is better - it's up to you to decide. Choose the quality that is more important to you.
If you decide to buy a gas water heater with a copper heat exchanger, do not try to find cheap model. In order to reduce the price, manufacturers use low-quality copper, and the tubes are also made with thin walls. Such a heat exchanger will serve warranty period, and then problems begin - a leak appears.
If you remove the casing, you will see fistulas in the tubes through which water drips. They are located mostly on the outside of the pipe, exactly in the place where condensation forms. If the pipe is of normal thickness, this is not a problem, but it quickly corrodes thin walls. Such a heat exchanger with a leak does not need to be replaced (it costs about 1/3 of the total price), it can be soldered. You will need refractory solder with a melting point of about 200°C, a powerful soldering iron and soldering flux. The technology of work is usual - clean the damaged area to bare metal, degrease, tin, and solder.
How to determine power
First of all, you need to decide on the power or performance of the gas water heater. These are two interrelated characteristics that simply reflect different characteristics unit. Performance is how many liters of water a column can heat per minute, and power is how much heat it can release. Some manufacturers indicate power, others - performance, so you need to understand exactly what you need.
Let's first figure out what kind of performance you need from your geyser. It depends on the number of consumers that need to be provided warm water. There are consumption standards for different types of equipment:
If you are connected to hot water kitchen sink, shower and washbasin, so that all three points work simultaneously and the water temperature does not drop, a capacity of 4 + 4 + 10 = 18 l/min is required. This is a lot, the price tag will be substantial. If you think about it, you will realize that all three devices are almost never turned on at the same time. There are situations when the shower and one of the taps work together. To provide them with hot water, the capacity must be 14 l/min. This is a little more modest, but quite enough for a comfortable stay. Look for the found value in technical specifications, it should not be less.
Now let's look at power. Gas water heaters can allocate from 6 kW to 40 kW of heat for heating water. Here the division is:
- a gas water heater with a capacity of up to 19 kW is suitable for heating water for one water collection point;
- for two points the power should be from 20 kW to 28 kW;
- three require more than 29 kW.
Now, you can definitely say which geyser is better in terms of power in relation to your needs.
What else to look for when choosing
There are a few more lines in the technical characteristics of geysers that are worth paying attention to. First, look at the minimum water and gas pressure that this model can work with. Imported gas water heaters from European manufacturers are more capricious in this regard - they are designed for stable pressure and do not tolerate changes well. But under normal conditions they work stably and without breakdowns.
Some manufacturers, in order to adapt their equipment to our conditions, install gearboxes that compensate for surges. If the model you like does not have such a device, and your water and/or gas pressure fluctuates, you can install the reducer in front of the entrance to the dispenser. This device is simply placed into a pipe break; installation is standard. At the same time, your other consumers will be protected.
It is also useful to review the list of utility programs and protection levels. The safety and comfort of equipment operation depends on them. It is highly desirable to have the following functionality:
- Gas control. Monitors the presence of a flame on the burner; if it goes out, it shuts off the gas supply.
- Traction control. The presence of draft in the chimney is controlled. If combustion products are not removed, the gas supply is shut off.
- Flow control or hydraulic valve. Turns off the column if the water pressure is too weak or there is none at all.
- Overheat protection. The temperature sensor monitors the temperature of the water in the heat exchanger; when it approaches a critical point (boiling), it turns off the column. This extends the service life of the equipment (if it boils, the heat exchanger can rupture, as can the pipes).
These functions are required for safe work geyser. This is almost a standard set that is found in all good gas water heaters. All others are optional. They, as a rule, are no longer so critical (for example, the remote control).
Geyser sizes and prices
Dimensions gas water heaters small - they are comparable to a small mounted kitchen cabinet. The average height is 550-650 mm, width 300-400 mm, depth 200-300 mm. But if you wish, you can find models that are wide and flat, or vice versa, narrow and deep. Which geyser is better based on this parameter can only be determined by reference to the installation site, so there is no definite answer here either.
Prices for geysers vary widely. Simple models with piezo ignition and galvanized burner cost from $110. Equipment with electric ignition and heap service functions- up to $450. So there is somewhere to roam.

An automatic gas water heater will give you many advantages. In particular, it will save you from the need to heat water on the stove, or even endure the inconvenience. An automatic geyser is an alternative to the central hot water supply, which often does not fully provide residents.
It's different from electric water heaters different types not only because it runs on gas, but also some nuances of the device. The machine is also characterized by automated control, which was not the case in Soviet-style geysers.
1 What is a geyser?
A good automatic gas water heater looks like a box or cabinet. It is not too big, but it is still worth finding a place for installation in advance.
From of this device both water and gas pipes, each of them is responsible for supplying its own resource. Inside the structure there is a heat exchanger - a serpentine pipe; it is through it that the water will flow, which will already be hot at the exit.
How the column works gas machine Neva is that there is a burner inside it, which, burning gas, heats the water with the heat it releases. That is, everything is simple and clear. Combustion products, which are naturally released when working with gas, are then discharged through the chimney.
2 What to look for when buying a geyser?
- The first thing you should know is that there are two options for a modern gas-powered dispenser. This is an automatic option and a semi-automatic geyser. The only difference between them is the method of igniting the burner. In the first option, everything happens automatically without human intervention. As soon as the water intake tap opens, the burner turns on and begins to heat. Automatic ignition is provided by batteries. This device is economical, since gas is used only when necessary. The semi-automatic device must be ignited manually every time you need to heat water. This is done with matches, which is not very safe, especially if the speaker has already had an impressive service life. A semi-automatic device is not as economical because the igniter is constantly on. But there is a semi-automatic and plus in the Bosch gas water heater. If something breaks in it, you can still light the pilot light with a match, which will still heat the water.
If you don’t know which option to choose, then decide what is more priority for you: savings and safety or insurance for the future. People's opinions on this topic are varied. Everyone is partially right.
Still, it is worth noting that everything breaks down over time, but this occurs less often with an automatic machine, since it does not work around the clock. Geysers with automatic ignition, however, are more expensive than semi-automatic ones.
- When buying a speaker, pay attention to the models at least average price. Since the cheapest ones will break, which is logical and proven by numerous reviews.
- Before buying, think about which one is more convenient for you: vertical or horizontal. Based on this, buy a device designed for a specific type of chimney.
- It is also better to buy a Bosch speaker with the power that would suit you. There is no point in overpaying for an automatic device with great opportunities, if you don't even have a chance to use them.
- It is also better to buy a speaker with an automated security system. Such a device will not turn on in case of certain breakdowns. A shutdown will also occur if there is a danger of explosion - this could be overheating or a clogged igniter, for example. Also, such a device will not turn on if there is no water or gas supply, which will protect it from damage.
- You can also purchase Neva geysers that would work on liquefied gas, which is sold in cylinders. Such a Neva column can be installed in a dacha where there is no central gas supply.
- It’s better to take a gas water heater that turns on as quietly as possible, because a constant or frequent hum is not always ignored by everyone and can seriously annoy some household members.
Such a device for heating water will cost at least 8-10 thousand rubles.
2.1 What kind of breakdowns can occur in the Neva automatic gas water heater?
Everything breaks down someday and needs to be repaired or replaced. To know whether to immediately contact a specialist or try to fix everything yourself, it’s worth understanding some types of breakdowns.
Often people are faced with the fact that the automatic gas water heater does not turn on. This can happen if the igniter is not working, it may be clogged. In this case, you need to invite a gas technician to clean it. You cannot climb to the gas yourself, as it can be dangerous.
Also, ignition may not occur if automatic device the battery is old. They simply change it and continue to use the heater.
Another reason that the Neva column does not work may be the lack of good traction. The chimney is responsible for this, which also becomes clogged over time. You can clean it yourself.
Water filters can also wear out, the heat exchanger becomes clogged, and scale builds up. The reason for this is the hardness of the water in the water supply. All this can be cleaned, but it is better to avoid it. To do this, you just don’t need to set the final water temperature above 70 degrees, since at this level scale will not yet form.
There are breakdowns that do not relate to either the plumbing or the gas part. It could be a glitch in the automation. , powered by electricity. With such problems it is better to contact the service maintenance. If the device is still under warranty, the repair will be free.
The geyser is a long-known, familiar and in-demand thing. The operating principle of this unit is more or less clear to everyone. In a column connected to gas and water supply systems, the following process occurs: you open water tap, And cold water under pressure enters the heat exchanger. Under its pressure it opens gas valve. Gas entering the main burner is ignited by the ignition device. The ignition system can be triggered automatically or manually (semi-automatically). According to this criterion, geysers are divided into two types: automatic and semi-automatic.
Semi-automatic speakers
The older generation of the post-Soviet space remembers Soviet gas water heaters well. Including such a column is not an entirely simple matter, it is quite responsible and requires some skills. To do this, it was first necessary to open the water supply connected to the column. Then open the main valve to supply gas to the ignition wick and light it with matches. Then turn on the main valve and only after that (if you did everything correctly) the column should turn on. But this all happened in the last century.
A modern semi-automatic speaker has a built-in piezoelectric element. The wick is also ignited manually, but not with a match, but by pressing special button. The wick in such a column always burns. When you open a hot tap, the column turns on, and when you close it it automatically turns off, but the wick remains lit. It is the presence of a constant light in the column that many consumers do not like. In addition, this column system is already somewhat outdated. Advanced gas flow heaters waters have completely automated system inclusions.
Automatic geysers
Modern automatic speakers in turn there are also two types:
- with battery ignition system;
- with a built-in hydrogenerator (hydraulic turbine).
To turn on any of these heaters, simply open hot tap. The first type of ignition requires replacing batteries, but they are not expensive at all and last a long time (at least six months). The second one does not provide any consumables, but is very sensitive to pressure and water quality. If there are problems with water pressure, it is risky to buy this unit.
We conclude: the most the best option heating water in modern house is an automatic gas water heater with a battery-powered ignition system. Convenient, reliable and safe.
