Rating of geysers: choose the best in terms of reliability and quality

An autonomous hot water supply system is extremely convenient. In many private houses and city apartments, gas water heaters are used for this. They have long and firmly entered into human life, fit perfectly into the interior of the kitchen, without spoiling it at all. A gas water heater gives the apartment owner a feeling of independence from the central heating supply, that is, annual preventive work will not affect the availability of hot water in the household. In addition, the column helps to save significantly - water is heated when it is really necessary, in the required quantities, and it is possible to adjust the level of temperature rise.

However, previously installed devices sooner or later exhaust their resources, therefore, both for safety reasons and to improve the comfort of use, they have to be replaced. And many homeowners are planning the initial purchase of such a unit, deciding once and for all to get rid of dependence on the central hot water system. In both situations, the problem of choosing the optimal model will certainly arise. The variety of assortment on sale sometimes even makes this task difficult. Therefore, we hope that the rating of geysers presented below will be of good help to the reader of this article.

But before moving on to the rating series, it makes sense to say a few words about the types of geysers found on sale, and about what parameters the model should be evaluated by.

Differences between a chimneyless device and a conventional one

A significant feature of the design of the device is a closed chamber into which street air is supplied using a fan (turbine). Traditional water heating devices use room air during burner operation through an opening located at the bottom of the column.

Any device operating on gas emits hazardous substances that must be removed outside. The turbo column is no exception, only here, instead of the usual chimney, a horizontal pipe (coaxial) is used, led out into the street through a hole in the wall. gas-type water heater with a closed firebox has several more properties:

• for complete combustion of gas, the turbine delivers air from the street using a coaxial double-walled (double-circuit) chimney, through which toxic gases are discharged outside;
• the device is equipped with multi-stage and modulating burners that can change the power and intensity of heating;
• there is no regularly burning pilot wick, piezo ignition button or traditional batteries to start the water heating process;
• a gas water heater
  without a chimney does not completely stop operating in automatic mode from the moment it is ignited until it is turned off;
• the electronic unit (controller) changes the air and gas flow in good accordance with the appropriate heating mode;
• turbocharged devices operate from the electrical network.

In most cases, gas-type with a coaxial chimney are equipped with an electric ignition system with electrodes to produce a spark. But not all types of columns use a mechanical hydrogenerator, which generates energy from a moving stream of water. Based on the properties of the devices, it is clear that they are equipped with a large number of purposes that increase comfort and operational safety.

Rules for operating a chimneyless gas water heater

Turbocharged water heaters are the best water heaters today. Most models operate in automatic mode, have simple controls and a multi-stage protection system. Basic rules for operating turbocharged water heating equipment:

• the first start-up is carried out in the presence of an inspector or other representative of the gas service;
• during operation, the water heater cannot be moved further than 1.5 m from its original location;
• the socket is installed away from the column with a gap of at least 0.4 m;
• if there is a smell of gas in the room or the water heater malfunctions, turn off the gas supply and call the emergency service;
• depending on the type of chimneyless dispensers, maintenance is required 1-2 times a year;
• in a gas storage boiler for heating water with a closed combustion chamber, the magnesium anode is regularly changed, regardless of the internal structure and type, the nozzles and burner are cleaned.

Before using the water heater, you should carefully read the operating instructions and carefully follow the manufacturer's recommendations. Thus, you can extend the service life and prevent common malfunctions and breakdowns of household appliances.

Operation of the unit with supercharging

All gas flow structures operate on the same principle: when the hot water valve in the apparatus is opened, the burner lights up under flow pressure and begins to warm the liquid circulating through the heat exchanger. In a turbocharged device, the process occurs a little differently:

1. While in standby mode, the device is connected to the electrical network. There is no combustion process in the chamber, since there is no ignition wick.
2. When you open the water tap, the flow meter and membrane fabrics of the water unit are turned on. Under its influence, a valve is activated, allowing gas access to the burner mechanism.
3. The controller sends a command to the electrodes located next to the burner, a spark appears that ignites the gas. The meter reacts to the flame and signals to the control unit, the spark formation ends, and at the same time the turbine is turned on, pumping air.
4. When the DHW tap is closed, the gas supply ends, the burner goes out, so the water heating process is completed.

Thanks to the improved design, the efficiency of a chimneyless unit can reach 88–90%, while that of an ordinary atmospheric unit is 84%. Effectiveness is determined by such functions:

• precise dosing of incoming gas and air needed for the combustion process;
• maintaining the required temperature regime is a function that allows you to save gas, since the consumption of excessive heating is eliminated;
• preheating of the street air flow with a coaxial chimney.

This function is the most effective, allowing you to replace the heat that is carried away with gas toxins. Cool air, entering through the same pipe, only in a different plane, takes heat from the oncoming smoke waste through the steel wall of the inner pipe.

Column

gas with a coaxial type chimney is equipped with safety features. They work in situations like this:

• lack of draft in the chimney due to the cessation of operation of the turbine, which stopped during a power outage;
• the burner went out spontaneously;
• reduced water consumption;
• controller function failure.

• lack of draft in the chimney due to the cessation of operation of the turbine, which stopped during a power outage;
• the burner went out spontaneously;
• reduced water consumption;
• controller function failure.

In any case, the gas

valve that shuts off fuel. It also reacts to power outages, burner extinguishing and pressure surges in the gas pipeline, without controller intervention.

Pros of a turbocharged device

There is no turbocharged column, and in devices that have a supercharging function, its design has been simplified. Now it is possible to use chimneyless devices not only in privatized houses, but also in residential areas. You just need to make a hole in the wall that communicates with the street and bring out the chimney

in a horizontal position along the shortest path.

If necessary, chimney can be placed vertically on the roof of a private building, having previously prepared a shaft for it from a material that does not burn. There are other positive qualities of a column with a coaxial chimney:

1. It is more efficient and economical compared to conventional water heating devices.
2. The closed firebox eliminates the emission of dangerous smoke gases and bad odors in the room.
3. The process of installing supply and exhaust ventilation is easy, since it is hardly possible to do without it.
4. The presence of a high degree of automation of the coaxial apparatus brings convenience to the operation of the equipment.
5. The function of energy carrier is usually performed not only by real gas, but also by liquefied gas. But this requires the use of a specialized hood located closer to the floor surface (propane is heavier than air).

In addition to the sensors that ensure safety and water temperature conditions, chimneyless units have an anti-freeze system for the heat exchanger. The working principle is this: at a low temperature in the room, a tubular-type heating element powered from the mains automatically turns on, which heats the heat exchanger and prevents the water from freezing.

The anti-freeze function in the coaxial column will be useful in case of unexpected shutdown of the heating system in winter. It will eliminate defrosting of expensive equipment and its failure.

Advantages and disadvantages

For apartments where chimney ducts are not provided, previously there was only one solution to heat water - an electric storage water heater. Since the appearance of forced-flow heaters, residents of such apartments have had an alternative option. This is one of the main advantages of columns with a closed combustion chamber. In addition, there are a number of advantages:

• there is no need to organize a flow of combustion air into the room; conventional supply and exhaust ventilation will be quite sufficient;
• the devices are highly efficient and economical;
• gas water heaters without a chimney are characterized by complete autonomy of operation and help create additional comfort during operation;
• when the fan and burner work together, surges in water temperature when opening several taps are smoothed out within the available power;
• the risk of various combustion products entering the house is minimized.

In addition to a large number of advantages, there are a number of disadvantages that also need to be taken into account when choosing a unit:

1. The described devices are quite expensive, this is due to the fact that the design includes auxiliary expensive elements and parts.
2. Turbocharged burners are a little noisy.
3. They are dependent on electrical energy, so it is not recommended to install them in areas that are prone to frequent power outages.
4. The design of the devices is such that the ability to service and clean the water heater yourself is excluded. In case of the slightest problems or malfunctions, you will have to contact service centers.

Summarizing all of the above, it is worth saying that the turbo gas water heater deserves special attention. Users note that with such devices they have made their life much easier. Their high efficiency and productivity are noted.

Disadvantages when using the device

The disadvantage of a coaxial gas water heater is its energy dependence. If there is a power outage, there will be no hot water. You will need to use an electric generator or a reliable uninterruptible power supply. Other negative aspects of these devices:

1. A coaxial unit running on gas is almost half more expensive than an atmospheric one. However, when comparing the purchase and installation process in combination, chimney will cost much less than making it out of brick or installing an insulated sandwich.
2. Fan noise can be heard on certain speaker models.
3. It is better to leave the cleaning of the device to a professional. Modern equipment does not have a simple structure, so it is not recommended to try to find the breakdown and remove it on your own.

To install a similar type of unit, you need permission from the organization supplying network gas. You should also inform your neighbors that a chimney will be installed on the facade of the house.

Features for installation in an apartment

To connect a standard gas water heater in a city apartment, the house must have a stationary channel for removing smoke. In most modern buildings, such ventilation ducts are laid in the walls, so connecting a chimney from a water heater to them is not a problem. However, many buildings of the last century do not have such channels, so it will not be possible to install a regular column in them. In this case, you can opt for a turbocharged model.

Other features of installing a chimney in apartments are the following nuances:

• The inside of the chimney should be smooth and without any narrowing.
• Most often it is installed vertically. No more than 3 bends are allowed.
• The pipe must be well sealed to prevent combustion products from entering living spaces.

As for the choice of pipe material, corrugated aluminum, despite its simplicity and low cost, is called an unsuitable option. Such pipes burn out quite quickly, so they are recommended only when the column is rarely used. For installation in an apartment, a steel chimney is preferable.

Boiler column with a closed chamber

of gas type device

, is a reservoir in which water is heated, and then distributed through pipe lines to water distribution points.
The water in the tank is regularly hot, and not at the moment the hot water tap is opened, as when using a flow-through heat generator. A turbocharged column
does not stop working according to a similar rule: when the temperature in the tank drops, the temperature sensor sends a signal to the burner device to turn on. During operation of the burner, hot air enters the smoke tube, surrounded by water, and transfers heat to it. As soon as the water heats up to the set mode, the burner turns off.

The container of the device is equipped with thermal insulation, thanks to which, akin to a thermos, it can keep the temperature for a long time. You can always use hot water very quickly and in the required volume. The capacity of the storage device tank is different for all models and can vary from 10 to 500 liters. The body is made of steel, covered with enamel or porcelain glass. The main positive quality of a storage water heater is the use of a large volume of hot water even when the water supply is completely turned off.

However, like any technological design, a gas water heater

without a chimney has a disadvantage - hot water remains in the gap between the hot water valve and the tank, which then cools down. Thanks to this, the client, after opening the tap, needs to wait until the cool water comes out.

This kind of problem is solved with the help of a circulation plant, which consists of a small pump that is connected by a pipe with a small diameter to a system of pipes leading to the end points. Using a pump, the remaining unused water is pumped back into the tank, thereby eliminating its cooling.

What to consider when choosing a chimney system ↑

1. Select the appropriate model of the chimney system. Select the necessary components for this design.
2. Chimney height. The smoke duct must be at least 4.5 meters in height. In this case, any narrowing of the channel is strictly prohibited, otherwise the thrust of the entire system will decrease.
3. Chimney diameter. It depends on the boiler model, but most often the standard value is 11 or 13 cm.
4. Climatic conditions. Gas equipment and the smoke exhaust system are quite susceptible to temperature changes that occur between combustion products and the environment.
5. The location of the chimney relative to the roof of the house. The chimney system must rise above the cover by at least 1 meter.

Tips for selection

It is impossible to give any specific recommendations regarding the place of purchase of a gas-powered device. It is necessary to focus on stores that are famous for their quality of service, different assortment, and the availability of good models.

Special plumbing and heating stores provide a huge selection of products, the parameters of which can be seen in person and the appearance of the column can be assessed. Purchasing through an online store also has its own positive qualities - the ability to exchange and return the product within 14 days without specifying the reason, a very large selection, ordering a rare model, reading reviews from other consumers.

The column is popular

gas Neva with a closed firebox.
This equipment is distinguished by flow-through heating of water, the use of liquefied gas, and the ability to connect to bottled gas. Based on operating practice, it is known that using this device you can obtain 6 liters of hot water per minute. The flow column
is equipped with sensors and timers that are responsible for the proper functioning of the instrument. Has a power of 9 kW.

When purchasing gas-type , the first thing you need to do is make sure that you have a decent security system for comfortable use of the equipment. It must be equipped with sensors that monitor flame, overheating and chimney backdraft. You can choose any ignition option based on your own wishes and desires.

When a chimney is not needed: chimneyless speakers

Nowadays, due to the spread of turbocharged speakers, it is precisely such devices that are called chimneyless, since they do not require a special chimney, and their coaxial chimney is discharged through the wall. However, there are also columns that discharge combustion products into the room in which they are installed. As a rule, these are low-power models with low performance. An example of such a dispenser is Neva 3001, whose power is 9 kW and productivity is only 2.6 liters per minute.

To install such a speaker, good ventilation of the room is very important, but even in this case there is a danger of carbon monoxide poisoning, because it has no odor and affects a person when he is not even aware of the mortal danger. That is why the chimneyless column loses to the turbocharged one and has recently been practically not used.

One of the options for solving the issue of hot water supply is to install a gas water heater. One of the important aspects of installing a gas water heater, on which ensuring high-quality draft and removal of combustion products, and, accordingly, efficient operation of the equipment depends, is the selection of a suitable chimney and its correct installation. Read an overview of the characteristics of a galvanized steel chimney on this page.

Specifics of gas-type water heaters without chimney

Residents of apartments or privatized houses cannot do without hot water. You just need to decide which device heats cold water best. Turbocharged column

very convenient to use and provides the hot water needs of all residents who use it. In some cases, it is most optimal to use gas boilers, in others, flow-type water heaters are perfect.

For multi-apartment high-rise buildings, the most comfortable and functional solution would be to use a turbocharged dispenser.

Installation steps

Installation of a chimney when installing a geyser includes the following steps:

1. Assessment of conditions for installation work.
2. Choosing a suitable chimney option.
3. Installation of the chimney section at the point of its connection with the gas water heater.
4. Installation of a chimney inside the house or on an external wall (for installation in a private house).
5. Exiting the pipe through the hole to the street (if a coaxial chimney is installed).
6. Checking traction.

Gas-type water heating device without chimney

The working principle of the geyser is to release the energy of the combustion gas, which is used to heat water, and it does not require any additional chimney. For such a device, it is most optimal to use liquefied or network gas from cylinders or an intra-house network.

This column

does not need the usual vertical chimney; it has a different system for removing gaseous, liquid and solid substances.
In such a device, the firebox is considered sealed , and the removal of gaseous, liquid and solid substances is carried out through a coaxial chimney
, which is discharged directly into the street through the wall. You need to immediately make a hole in one of the walls when installing a turbocharged column. This device has a built-in fan that directs gaseous, liquid and solid substances in the required direction.

Through the inner part of the coaxial pipe, carbon monoxide is discharged to the street, and fresh air, which is intended for the combustion process, enters through the external channel.

This column

It is also convenient in that it does not dry out the air in the room and does not require additional air flow to support combustion.
Due to the fact that there is no need to install a separate vertical chimney, it is possible to significantly save on the purchase of materials and installation work.
When selecting a turbocharged gas water heater, the following characteristics are first taken into account:

• productivity;
• type of ignition;
• power;
• security parameter;
• types of burners.

An important factor is the method of placing the device - horizontal or vertical, due to the fact that the combustion product exhaust system in a wide variety of columns is designed differently.

The disadvantages of this device include the increased temperature of the exhaust gases, as well as the lack of an additional pipe for draining water.

The characteristics of the storage geyser-boiler “BAXI SAG3 300” are presented in the table:

Power and Productivity

Correctly selected power affects the operating performance of the device. It is the main parameter of the geyser , which is primarily taken into account when selecting a water heater. A high power level provides a much larger volume of water heated in instantaneous heating mode.

The instructions for the device must indicate its productivity , in other words, the volume of hot water that a flow-type water heater creates in one minute of operation, taking into account the increase in water temperature.

For example, at a temperature of 25 degrees mentioned in the instructions, the buyer can get 14 liters of hot water in one minute. If at the entrance to the gas-type

If the water temperature is 8 degrees, then thanks to the operation of the device it rises by another 25 degrees and at the exit it will be warmed to 33 degrees.

Modern flow-through boilers, which operate without the use of a conventional chimney, have 3 types of ignition systems - hydroturbine ignition, piezo ignition and electric ignition. They make the column easy to use and safe.

Hydroturbine ignition is performed from a hydrodynamic generator. Many current devices have installed mini-hydroelectric power stations, the generator of which is mounted in the wire of the water heater pipes. The incoming water flows through the turbine, rotating its blades, and the generator begins to generate the necessary electricity for the ignition wick. Such water heaters do not need to install additional energy sources needed for ignition.

Piezo ignition has a special element that generates electrical potential from the action of mechanics, which causes a spark to appear, with the help of which the burner is ignited. Such ignition has one drawback - the ignition wick must be in a burning state in advance so that when the water is turned on, the main burner will light.

Electric ignition requires connecting the speaker to an electrical outlet or installing power components, such as batteries or rechargeable batteries. When the tap is opened, the water pressure meter is triggered, which gives the command to ignite the ignition wick using a spark gas discharge device.

Features for installation in a private home

If you thought about a chimney at the construction stage of a building, the best choice would be to install a vertical brick shaft, inside of which a steel or asbestos pipe can be located. At the same time, it is important that the gas water heater and the heating system have different shafts for removing smoke.

If the building has already been built, the most suitable chimney option is an insulated steel pipe. It can either be attached to one of the external walls, or installed inside the building through its ceilings and roof.

Other nuances of installing a chimney in a house are the following:

• The material and design of the chimney, as well as the installation location, must comply with current regulations.
• The chimney must be easily accessible so that, if necessary, possible problems can be quickly eliminated.
• When installing a chimney vertically in a house, it is important to prevent a significant deviation of the pipe - it should not deviate more than 1 meter throughout the entire structure.
• The end of the chimney pipe should protrude at least 40-50 cm above the roof.

Control system for gas dispensers

Burner flame control can be variable or constant with stepped power.

1. Columns with variable control, after setting the desired temperature regime, begin to work stably, supplying water at the output at the required temperature, regardless of external factors. As a rule, such speakers are an electronic push-button system with a digital display.
2. Water heaters with burners of stepped power allow you to adjust the burner flame on your own, achieving the desired water temperature. But here external factors have a serious influence, for example the temperature of incoming cold water or changes in atmospheric pressure, which can significantly affect the water heating temperature.

The temperature is changed by turning the tap handle in either direction. You cannot tighten it too much, as it may have the opposite effect - the instantaneous water heater may simply turn off. With such an adjustment, it is forbidden to mix cold water from the tap and heated water using a column.

Advice from experts on choosing speakers for an apartment or home

If the speaker will be used in the bathroom - in a damp room - experts recommend choosing only semi -automatic models . Steam from hot water negatively affects the operation of all electrical components inside the column.

Vending machines can only be installed in the kitchen.

First, you need to determine the water consumption, and then use these values ​​to select the power of the unit. Power must be selected with reserve.

should be correlated with the power of the column . If the pressure created by the pump is small, a too powerful column will not heat the water, but boil it. In the summer this is completely useless. To choose the right devices, it is recommended to make calculations before purchasing, and also take into account the number of water consumption points.

Safety of turbocharged speakers

Many people consider the operation of gas-powered dispensers without chimneys to be completely harmless, but it is still best to follow specific precautions and rules for the safe use of the device.

If for no apparent reason one of the components of the water heater system fails or the coolant overheats, the column

will turn off automatically. This proves the very high safety of a gas-powered appliance only if it is installed correctly.

However, if this device is installed in an apartment in a high-rise building, and there are a couple more floors above this apartment, then the coaxial pipe that removes gaseous, liquid and solid substances from the heater can become very dangerous for residents present on the upper floor. The carbon monoxide coming out of the pipe begins to rise and the air flow can easily carry it into the open window of the apartment located above, which can create big problems.

Therefore, before installing this equipment, it is best to consult with gas service workers. But in privatized houses or residential areas that are located on the top floor, such a column can be installed without any fear of causing harm to anyone.

Before purchasing an expensive gas-type without a chimney, you need to evaluate its pros and cons. Moreover, you should find a place where it will be placed. If anything causes suspicion or difficulty, it is best to turn your attention to other types of water heaters.

How to choose a gas-type water heater that does not require a chimney?

Types of columns without chimney

Everyone needs hot water, in any weather and whenever. Gas-type water heaters can provide us with such an important event for our everyday comfort.

(columns), thanks to which, regardless of the central water supplier, we will begin to use hot water.

Turbocharged column

- a device that will be the best option in situations where there is a need to provide hot water in an apartment, a house of several floors - where the presence of a chimney exhaust is either unrealistic or was not calculated by the developer.

Plus, this type of gas-powered dispenser is also called a chimneyless turbocharged dispenser

may be the best solution if you need to save as much space as possible in your home, on your summer cottage, or in a room for industrial needs.

Column

without a chimney - an original engineering design, which, by introducing a modern type of firebox, and a radical change in the system for removing gas waste products, created a new type of gas-powered, multifunctional dispensers.

Criterias of choice

To make the right choice of model, you need to study the device parameters and take into account important installation nuances:

• First, they decide on the place where the water heater will be installed. Based on the location in the room, it is easier to determine the dimensions of the device, as well as calculate the cost of purchasing additional materials for installation, such as pipes for exhaust and water.
• Burner power is the first parameter that requires attention when choosing a column. For domestic use, models with an average rating are suitable, capable of providing hot water to 1–2 points. If analysis is carried out simultaneously from 3-4 points, you will need a device with a higher power burner.
• The performance of a gas water heater is determined by the consumption of hot water. The optimal rate is in the range of 10–11 l/min.
• The automatic water heater has a threshold for maximum and minimum water pressure in the water supply. If these values ​​do not match, the column simply will not turn on.
• Most water heaters are designed to be connected to a centralized mains, but there are water heaters that run on bottled liquefied gas.
• They choose a speaker not because of the popularity of the manufacturer, but by the availability of spare parts and their cost. There is no such water heater that will constantly work without repair.

Modern manufacturers are trying to equip their products with additional functions. Most of them are unnecessary, and you shouldn't overpay. There is a competent opinion: the more a device is endowed with additional functions, the more capricious it works and the more expensive it is to repair.
