Geyser with automatic maintenance of temperature. Which geyser is the most reliable? Choosing the best

The Russian market of water heaters is presented various models from leading manufacturers. However, in terms of efficiency, an individual source of hot water supply is clearly in the lead - geyser. Owner reviews highlight them aesthetic design, ease of operation, small dimensions, long service life and economical fuel consumption. Choosing a geyser is a difficult process that requires knowledge of the basic characteristics of water heaters. In large supermarkets, a huge range of water heaters is presented, which differ in their properties and functionality. In this review, we will try to figure out how to choose the right gas water heater.

Before we explore how to choose a geyser for a summer residence and an apartment, we will consider the distinctive features of an instantaneous water heater. These devices differ in that the water is directly heated in a copper heat exchanger by a burner flame. The temperature of the water is maintained by changing the intensity of the flame.

The main modular elements include:

1. Power supply that coordinates the operation of all nodes and provides a multi-stage control system.
2. Gas and water control device for safe and optimal performance device over a wide power range.
3. modular burner.
4. The display for indication of temperature of the warmed up liquid.
5. A heat exchanger designed to provide heat transfer from heated gases to running water.
6. Chimney with draft sensor.

2 pipelines are connected to the body of the water heater: one supplies cold water, the other, respectively, gas. The lower part of the instrument is equipped with the main and pilot burners. When a water faucet is opened, gas flows through the valve. It causes a fire from the pilot burner to the main burner. The water is thus heated as it passes through spiral tube located in the heat exchanger. At the same time, emissions of harmful substances disappear through the chimney, and hot liquid enters the tap. Automation of processes in the column allows you to quickly get heated water.

Basic selection options

To consider which gas burner to choose for a room, let's get acquainted with the main distinguishing features of heating appliances. They differ in appearance, type of combustion chamber, power, type of ignition, gas pressure in the system, different removal of combustion products and additional functional characteristics.

Types of combustion chambers

The geyser may have open and closed combustion chamber. In the first types of equipment, the flame burns out with the air that comes from the room. For this, a fence is provided below. Combustion products are removed through a special chimney, which is in any apartment.

Speakers with closed cells to support the fire using oxygen from the street. A coaxial chimney is mounted with a water heater. As a result, the products of combustion are removed using the built-in fan. The devices are complex and expensive.

Note! For speakers closed type power is used to run the fan. In the event of a power outage, there will be no electricity and hot water.

Water heater power

The next important parameter that the user should pay attention to when choosing a gas water heater is power. It depends on it the performance of the device. This characteristic shows the amount of water that the device can heat in a certain period of time.

• low - 17-17 kW;
• medium - 22-24 kW;
• high - 28-31 kW.

Depending on the tasks that the device must solve, the technical characteristics of the water heating device are selected. A powerful gas column will be needed for work several water points, models with low power, as a rule, provide hot water for a kitchen sink or shower room.

Attention! When choosing a water heater with a burner, remember that the performance is indicated taking into account the heating of water to a temperature of 25 degrees. If it is necessary to increase the heating temperature at low pressure, then the performance will be different than that stated in the device's passport.

Ignition type

Depending on the way the gas column is turned on, there are electronic, manual ignition and piezo ignition. Gone are the days when the wick was lit with matches. Now you can light the burners automatically or using the buttons. Let's consider each of the options.

1. Ignition from batteries. It turns on automatically after the tap opens. Batteries are the source of energy. Their resource is enough for 3-4 months.
2. Ignition from hydro turbine. This type of igniter is used in expensive models. The source of energy is an electric generator. This option is suitable for those whose water pressure is more than 0.35-0.5 bar.
3. Piezo ignition. With the help of a special button with a piezoelectric element, the wick is lit. Since the location of the button is inconveniently located, it is difficult for owners to use the pier ignition.

Geyser with battery ignition

Device management

A gas water heater should be not only functional, but also convenient to use. It can be regulated, in addition to the level of gas supply, its pressure. In this case, the column will work at reduced water pressure in the tap. Availability liquid crystal display will allow you to see the main parameters of the device:

• outlet water temperature;
• flame modulation;
• error codes in case of device malfunction and other parameters.

Column safety

Despite technological progress, this parameter must be taken into account when buying a geyser. How to choose a gas water heater that is safe to use? Some mandatory requirements apply to the device:

• in the event of interruptions in the supply of gas or water, the unit should automatically turn off;
• if the gas supply is resumed, there should be no leakage;
• in case of weak draft, the unit is automatically switched off.

To meet these requirements, manufacturers equip the device with special sensors.

1. Ionization sensor. If the flame goes out, the system itself turns off the gas supply.
2. Flame sensor. It performs the same functions as the previous device, if the ionization sensor does not work.
3. Relief safety valve designed to control the pressure of water through pipes.
4. flow sensor. The purpose of this function is to automatically turn off the device if the tap is closed and vice versa.
5. Thrust sensor. Prevents people from carbon monoxide poisoning in the absence of traction.
6. Low pressure sensor. Thanks to this protection system, the column will not turn on if the water pressure is low.
7. Overheating sensor. The main task is to control the temperature of the water: if it rises, the equipment turns off. This additional safety feature prevents pipes from bursting.

When buying, consider the presence of all these sensors. If any of the listed devices is not present, then the column cannot be called safe.

Which is better - storage or instantaneous water heater

A storage water heater is a boiler that has a built-in heating element and a thermos tank that holds warm water. In the flow version, there is no such capacity, it becomes warm during the operation of the column.

Here is a table comparing the two types of models:

Thus, in small families it is quite possible to use an instantaneous water heater, and in a spacious house you can no longer do without storage equipment.

The best storage water heaters

Such devices are most often designed for outdoor installation. In fact, these are ordinary boilers that only work on gas. They pre-heat water, which accumulates in a special tank. Its average volume is 150 liters. Among the best geysers in this rating are the most interesting models.

This is a good floorstanding speaker for those who spend little time at home or live in an apartment alone. Its power is not very large, 8.65 kW, so the water does not warm up quickly, but with high quality. The presence of a built-in thermometer allows you to control this process, although the device quite successfully copes with this on its own. The stainless steel body ensures a long service life.

The best instantaneous water heaters

As the name of the category implies, these models of geysers heat water directly at the moment it is supplied to the faucet. This makes them cheaper storage heaters and their choice in the market is much wider. In the category of the best gas water heaters, we present 4 models of flow type.

The column is included in the rating due to its convenience and practicality. It is ignited at the touch of a button thanks to the piezo system. At the same time, the strength of the flame can, if necessary, be adjusted, depending on the flow of water. This allows you to use it in the bathroom and in the kitchen at the same time, without losing temperature. Even when operating at a maximum power of 26.2 kW, the gas consumption does not exceed 2.1 m3 / h, and the liquefied one consumes almost half as much.

Which gas column is better to buy

If you want the equipment to serve both the kitchen and the bathroom at the same time, then its productivity should be above 10 liters per minute. For work in Khrushchev, especially on the top floors, it is important that the device can operate under conditions of low gas pressure (below 0.15 bar) and low water pressure. Those who do not want to control its operation should pay attention to models with electric ignition and a flame modulation option. To minimize heat loss, products with a heat exchanger made of copper or steel allow.

Here's what you can choose, depending on your needs:

• For one or two people, the Ariston SGA 200 or Baxi SAG3 100 option will be enough;
• In private homes, the powerful Bosch Wr 10-2p model will be very appropriate.
• In an apartment, especially in old houses, Ariston Fast Evo 11C will be relevant.
• To service several points of water intake, it is best to choose the Electrolux GWH 11 PRO Inverter.
• If needed a budget option, then you should pay attention to the geyser Neva Lux 5514 or Superlux Dgi 10l.

The rating included only the best gas water heaters on the market, but, as you can see, they also have certain nuances. Therefore, before buying, you must carefully read the description and characteristics of the product.

The choice of gas equipment must be approached from the point of view of safety and reliability. Buying a cheap water heater can be fatal for its owner. It is necessary to familiarize yourself with the basic requirements for the maintenance of gas equipment. Do you agree?

We will tell you how to choose a geyser in order to purchase the perfect unit. The article we have proposed describes all the criteria that can affect the choice of gas wall-mounted equipment. We present popular models among consumers from proven manufacturers.

The general principle of operation and the device are characteristic of all models of gas-fired instantaneous water heaters. Propane enters the column through the nozzle. A valve is installed in the pipe that regulates the gas supply.

Water is brought to the adjacent branch pipe in the geyser. A control valve and a sensor are installed in the branch pipe. When the sensor is triggered, the gas enters the burner through the nozzle. The gas ignites in the burner.

In old Soviet models, the gas had to be ignited manually. In modern, three methods of igniting gas are used:

1. from a piezoelectric element.
2. From batteries.
3. from a hydro generator.

Piezo ignition means pressing the button every time you use the gas column (if you use gas economically). This is inconvenient, but more reliable than using automatic ignition, where the gas is ignited by a spark that is supplied by candles.

Image Gallery

The membrane in the block rises under the pressure of the water and exerts pressure on the stem, which turns on the gas. If traction is present, then it turns on gas-burner. Water passes through the tank and heats up.

What elements should you pay attention to?

When choosing a column, preference should be given to models with a copper heat exchanger. It may be covered with solder, but should not be made of thin sheet metal. Most often, models of Chinese manufacturers have tin heat exchangers. The service life of such columns does not exceed three years.

Regardless of the ignition method, an automatic type geyser starts working when water passes through the water block. If there are problems with the supply of a spark, then the cause, first of all, must be sought in the block (+)

Low cost achieved due to the cheap quality of the metal, which burns out over time. This leads to the need to purchase a new gas column.

Another important characteristic of the heat exchanger is the inner diameter of the tubes. The wider the tube, the less often it is necessary to clean the heat exchanger from scale and small debris from old water pipes.

It looks like a low-quality heat exchanger, which is installed on cheap models of instantaneous water heaters. Inside you can see that the metal is not made of copper and is an alloy of unknown origin.

Also an important detail is the water block of the column. This element must be made of metal. There are models made of plastic.

It looks like a quality heat exchanger that will last more than five years. It can be visually seen that it is made of copper and has sufficient thickness. Some manufacturers cover this element with solder or other coating.

Since the block also contains a mesh filter that needs to be changed, frequent unscrewing spoils the plastic thread and leads to the need for a complete replacement of the water block.

What parameters should be taken into account when choosing?

Before choosing the best option or a private house, you need to decide on the volume of water that comes from the tap. It is necessary to determine how many liters per minute flows out of the tap. To do this, the easiest way is to use a water meter if it is installed in an apartment on a pipe.

To do this, you need to record the readings on the counter. Next, you need to note the time and open the tap at full power, draining the water for exactly a minute. After that, you need to close the tap, and record the readings on the meter again. Then you need to subtract the primary indicators from the final indicators. The resulting number will help you choose the right model for performance.

If the value obtained is less than 10 liters, then it makes no sense to buy models with a capacity of 13-15 liters or more. If the house has old pipes in which the pressure often decreases, then a model with a reduced threshold is needed, otherwise the column will turn off when the water pressure decreases.

Regulation of water and gas supply

According to the method of controlling the water temperature, geysers are divided into manual and automatic. Models with a manual setting method are cheaper than with an automatic one.

Manual regulation implies the presence of two valves on the body of the geyser. Increasing the gas supply leads to more intense combustion and heating of the water. If increasing the gas supply is not enough for optimal heating, it is possible to reduce the pressure of the water entering the column.

The disadvantage of these models is the lack of modulation of the flame in the heating pad. When using two points of water intake at the same time, the water temperature will change. This is uncomfortable, especially if a person is taking a bath at this time.

Models with electronic ignition keep the temperature set by the user. This is achieved by modulating the flame in the burner, depending on the pressure of the water used. Maximum deviation from the specified temperature regime is between 1 and 3 degrees Celsius.

It is very important that the heating of water when turned on runs smoothly, without sudden jumps. If the burner first heats up a lot, and then lowers the temperature, you will have to wait for the water temperature to normalize. This increases the water consumption.

Landmarks on the method of gas ignition

Speakers that are ignited by a piezoelectric element are more reliable than automatic counterparts. Models with a piezoelectric element allow you to manually control the gas supply to the column, unlike automatic igniters. In these models, it is possible to leave the flame on the pilot burner in normal mode.

This allows you not to re-ignite the column with each use. The flame is maintained in the pilot burner and ignites the main heating element when the sensor detects water flow.

The location of the ignition button differs in columns from different manufacturers. In some models, in addition to pressing the button, you have to move the slider

Water heaters that receive a spark from a battery-powered igniter cannot be installed in rooms with high humidity. Condensation forms inside the plastic battery case. Over time, metal parts become damp and need to be completely replaced.

The batteries themselves should be changed as needed. At constant use instrument replacement frequency increases. It is better to use high-quality batteries, they last for a year or more

Columns ignited by a hydro generator are noisy. They emit a small whistle, reminiscent of the wind. In expensive models, this problem is solved by soundproofing the case. These water heaters also turn on when a hot tap is opened. Visually, the hydrogenerator does not stand out, as it is installed in the water heater housing.

According to the method of removal of combustion products

Flowing gas heaters require the removal of combustion products. The safest withdrawal method carbon monoxide is a chimney with a pipe outlet to the street.

The more powerful, the wider the diameter of the chimney pipe. If a water heater is bought to replace a failed device, then you need to measure the diameter of the pipe so that there is no need to dismantle the old one.

On Russian market you can find models of instantaneous gas water heaters without a chimney. Their placement in a confined space is hazardous to health. It is highly undesirable to install them in rooms without ventilation holes in the walls.

In the bathroom, their installation is prohibited, as there is a risk of carbon monoxide poisoning. A distinctive feature of these models is low power. The article we recommend will acquaint you with.

How oxygen is supplied

In budget models of geysers, there is no bottom cover on the case, or there are ventilation holes on the body of the device.

The disadvantage of this device is the partial ingress of combustion waste into the apartment through these holes. In addition to carbon monoxide, propane can leak

In expensive models, a different oxygen supply device is used. It is a pipe that is removed from the column in its lower part. Additionally, the body of the column is closed by the lower and upper covers, which does not allow carbon dioxide to enter the apartment. The effect is achieved by convection.

How to determine the required power?

Water heaters of low power (17-19 kW) are designed for systems with a small and serving only one point of consumption. They are installed in houses with old pipes.

No point in buying more powerful column if the system flows less than 10 liters of water per minute. It's a waste of money

If the apartment has good water pressure (10-14 liters per minute), then you can choose a gas water heater for two hot water supply points. Water heaters of medium power (20-24 kW) may react poorly when the pressure in the system decreases if it is not enough to turn on automatic system gas ignition.

High power geysers (28-31 kW) are not intended for apartments. They are used in private country houses. Some manufacturers produce modular columns specially designed to work as a single water heating system.

Conclusions and useful video on the topic

The video shows frequent breakdowns gas water heaters:

What is dangerous self-installation of a geyser:

After the choice of the water heater is made, you need to order the installation at the manufacturer's service center. Only in this case, the guarantee for the geyser is valid. This practice applies to all major suppliers.

Savings on installation leads to waste on repairs, which you will have to pay for yourself. The column must be registered with the gas service, since once a year it must be inspected by specialists.

Tell us about how you chose a geyser, what criterion became decisive in choosing equipment. Perhaps you have stock helpful advice for site visitors planning to buy a gas wall-mounted boiler? Please write your comments in the box below.

Water heaters are necessary not only for residents of the private sector, but also for people living in apartments. The central water supply is not always stable, the water supply is turned off to repair and prevent the system. In the summer, without hot water supply (hot water supply), it is difficult. Which geysers are better to choose in order to feel comfortable at any time of the year? What equipment to buy for installation in Khrushchev, a private house or a modern apartment? To help you choose, we have compiled a list of the most best models according to users and experts.

Which gas column to choose? With some criteria you need to decide before going to the store. Look around your premises. Is it spacious or cramped? Is the wiring installed old or new? How long have the pipes been changed? Why the answers to these questions are important, you will now find out.

Device power. More powerful devices consume a large amount of electricity, so they require connection to thick wiring. It is worth focusing on the number of sampling points. So, a low power of 9-20 kW can provide one point of intake. Average 20–24 kW - two points. High 25 kW and above - two points with stable operation or three with pressure drops.

Combustion chamber type. Products open type are a classic design. The air that is needed to burn the flame is taken from the room. Therefore, it is important natural ventilation. The products of combustion are removed through the chimney.

closed kame ra provides for the installation of a coaxial chimney. It is based on the principle of a pipe in a pipe. Combustion products are removed through one tube, oxygen for combustion enters through the other. The safety of such devices is much higher. Therefore, they are preferable for installation in a residential area.

Ignition type. This is an important criterion on which the convenience of using equipment depends.

• With auto ignition. The burner ignites when the mixer is opened. There are water and gas regulators on the panel, it is possible to have a display.
• With piezo ignition (semi-automatic). To start the burner, you need to hold the button. The cost of such models is lower, but in operation they consume a large amount of fuel.
• Manual ignition was used in older models. It is inconvenient and unsafe.

Safety. When buying, pay attention to this criterion. The presence of flame sensors, thrust, temperature allows you to protect the device from damage, and the user - from poisoning. If the column fails, the sensors signal the control module, after which the operation is turned off.

Choice problems

Which devices are better - domestic or imported? Someone thinks that Russian and Belarusian speakers are the most reliable. The cost of products is much lower than imported ones, besides, they are easier to repair and find spare parts.

Foreign products are often assembled in our country from Chinese parts. Of course, this is much more profitable for manufacturers. It turns out that the client overpays only for the brand / brand, but the equipment is the same?

Another example in favor domestic manufacturer. Products are adapted for normal operation in our "not normal" conditions. That is, the column can operate at a minimum system pressure of up to 0.1 bar. And this is true for residents of Khrushchev, where the old water supply is installed. The most famous manufacturers are "", "", "Don". Staurolit and Vestal are also in demand.

On the other hand, if you turn to an official supplier, you can purchase high-quality imported equipment. Yes, it will cost more. Yes, in the event of a breakdown, you will have to order original spare parts. But reliable parts, high-quality components and materials will do their job. Such a product can last more than 10 years. Much depends on the operating conditions.

Sergey

Powerful and high quality speaker. Suitable for hard water, I have been in operation for the fifth year. This is despite the fact that in the water there are impurities of sand that precipitate. So I added a filter. The assembly is good, it provides stable 2 intake points - in the kitchen and in the bathroom. Periodically I clean the heat exchanger, because not a single device can withstand such water for a long time. In general, I am satisfied with the work. One minus - the regulator cannot turn off the operation of the batteries. Pulling them out every time is inconvenient.

It can be connected to a common line or run from a gas cylinder. The device works quietly, which will not prevent the owners from spending time in the kitchen.

The cost is from 8 000 rubles.

Julia

I chose a water heater for a long time and settled onBosch WR 10-2P with piezo ignition. Met negative feedback that the radiator is leaking. I have been using the equipment for three years, no problems. It is necessary to clean the heat exchanger in time and not set a high temperature. Adjusted once, and after that stably issues hot water. I recommend to buy.

Even the best, according to buyers, technology has its drawbacks and advantages. No wonder they say that best repair is prevention. If you have made your choice trademark devices, we give several recommendations for long-term operation:

• To install the product, it is better to contact a specialist.
• It is not recommended to mix hot and cold streams on a mixer.
• Once a year, inspect the column nodes.

We wish you a good choice!
