Under the common term " geyser" refers to a gas instantaneous water heater - a household appliance that provides hot water by heating it using a gas burner. This equipment is used in many houses and apartments. Geyser, which is better and which is worse - reviews from customers and specialists presented in our review will help you understand these issues.

Gas water heaters, their types and choice

It can be difficult to choose a geyser for an apartment or private house - this is due to the variety of models, which often do not differ from each other or have minor differences. Consumers are also confused by the opinions of sellers that do not always agree with each other. Some of them praise certain models, others praise competitors' products. As a result, buyers, unable to stop their choice, begin to study reviews of geysers.

Expert reviews can be more useful than any other information, because they are given by those who have already encountered certain models. Let's see what properties the hypothetical most reliable gas water heater should have:

• No breakdowns throughout the entire service life;
• High-quality heat exchanger;
• No leaks;
• Accurate operation of electric ignition;
• Minimal maintenance required;
• Stable operation even with fluctuations in water and gas pressure.

Some geysers have a long service life, while others begin to act up from the first day of operation.

Sometimes it happens that devices from leading brands break down almost every day, while cheap Chinese geysers (for example, some Vektor models) work like a good Swiss watch.

Let's look at the main types of geysers:

• Domestic and foreign consumers tend to choose imported models, often ignoring Russian-made models;
• With electric ignition, piezoelectric ignition and hydrodynamic ignition;
• With flame modulation or simple mechanical control - the former are distinguished by maintaining a stable temperature;
• With open and closed combustion chambers;
• In terms of performance, geysers are available for sale, providing from 5 to 25 liters of hot water per minute.

When developing geysers, manufacturers use various technological solutions, which affects the reliability of the design. And here there is one small rule - the more expensive the device, the better it is. There are exceptions to the rule, so you should rely on it with caution.

Let's see how to choose the right gas water heater for an apartment or household, and what is best to pay attention to. This information will be presented in the context of reviews received from specialists and customers. The review will include models produced in 2016 and 2017, as well as samples released several years earlier, but still being sold.

Reviews from specialists and buyers

Choosing a geyser is not an easy task, because every consumer wants to have high-quality and reliable equipment, which will not bother you with frequent breakdowns and leaks. Especially for you, we have compiled a unique rating of geysers in terms of quality and reliability, collecting the most popular models.

Alexander, 47 years old

The best geysers are made by the Conord plant. It probably couldn’t be simpler and more reliable. I bought the speaker for 4 thousand rubles. The Don water heater is lightweight and reliable, with a beautiful front panel and good performance. Connects to ordinary chimney, and according to its internal structure it simpler than a brick. Three years have passed since installation, during which time there has not been a single breakdown. It makes moderate noise, like any other model with an open combustion chamber. It’s easier to adjust the final temperature with a mixer to your liking.

Flaws:

• Demanding on batteries - we tried using cheap batteries, they ran out in literally 3 weeks. Therefore, you have to buy expensive alkaline ones;
• I didn’t really understand the purpose of the “winter-summer” knob - as a result, the column works year-round in one position of this knob;
• The adjustment knobs are not the most accurate - you have to suffer before you get the desired mode.

Russian geysers the better that they are adapted to our conditions.

Efim, 34 years old

I was faced with the task of choosing a gas water heater for a private home. The double-circuit boiler was immediately brushed aside - I work in a heating equipment store and I know how much trouble this unit can cause. It is best to install a separate heating boiler in the house, and in conjunction with it a boiler and instantaneous water heater. I didn’t have room for a boiler, so I settled on a simple gas water heater. It does have some drawbacks, but I don’t see the point in overpaying 10-15 thousand rubles and getting about the same thing.

Advantages:

• There are no unnecessary functions - believe me, all of these additional options in most cases they are not needed, you are unlikely to use them;
• Quite quickly reaching the set temperature;
• It ignites quickly and without making a noise.

Flaws:

• Sensitivity to the temperature and pressure of incoming water - at the slightest fluctuation in these parameters, the outlet temperature begins to “float”;
• It may go out when you try to add cold water with a mixer - this happens when you suddenly open a “cold” tap.

But in general, the device is very good, it has been in the house for two years, there have been no problems so far. Although I know a lot of examples when complex double-circuit boilers started to fail in the second year.

Kirill, 34 years old

It’s hard to find a better one for an apartment than this geyser. One of the most reliable devices I have ever installed. The most difficult thing is to persuade the client to pay a significant amount for this model, since everyone is trying to save money. The manufacturer has done everything possible to make the water heater truly reliable. Inside we will see a durable heat exchanger that takes maximum heat from the burner. The unit is equipped with electric ignition, unlike older models that had an igniter. Therefore, now there are concerns about own safety unnecessary.

Advantages:

• High efficiency - on average, this figure is higher than most models. In practice, this leads to savings of several percent on gas fuel;
• A solid heat exchanger - this is not foil, but durable metal. As a specialist, I can say the same about the burner;
• The desired temperature can be easily set without tedious turning of the knobs.

Flaws:

• When you turn it on, sometimes it manages to overheat the water, so you don’t need to immediately put your hands under the stream - it’s better to wait a few seconds;
• Older models use ignition with a pilot light, which can overheat the water even more during the initial start;
• If you open two taps at once, the gas water heater may not be able to cope with the supply. required quantity water.

If you need a gas water heater for a private house or apartment, and you don’t want to waste money, it’s best to pay attention to this model.

Alexey, 29 years old

Our company recommends modern geysers for apartments and private houses. The time for using traditional units with simple mechanical controls has already passed. The future belongs to more advanced models with electronic control. A typical example of this is a device from Hyundai under the tricky name H-GW1-AMW-UI305. Its productivity is 10 l/min, Maximum temperature heating is +60 degrees. There is electronic flame modulation here - the geyser can independently maintain the set temperature. It also has a self-diagnosis system that detects breakdowns.

Advantages:

• Stable outlet water temperature – forget about constant fluctuations;
• Reliable heat exchanger - will last for several years without repair or replacement;
• Convenient electronic control - just set the desired temperature and forget about further settings.

Flaws:

• You cannot enable two parsing points at once - it is best to use them in turn;
• It doesn't work as quietly as we would really like.

The main advantage is the optimal ratio of price, quality and functionality. There is nothing superfluous, there is flame modulation, a long service life - it’s simply not better to find.

The estimated price of this model on the domestic market is about 7.5-8 thousand rubles. It is better to buy a geyser in an online store, where its price may be lower.

Oleg, 30 years old.

My grandmother’s old Soviet-made gas water heater broke down - it often leaked, and during operation it hummed and made noise like an aircraft turbine. We went to the store to choose a new one. We put Chinese models aside, they are unreliable, often break, and the quality of their internal filling does not stand up to criticism. We settled on a model from the well-known company Ariston, with electronics. But they didn’t notice the expected quality, that China and Italy are all the same. Within six months, a puddle of water formed under the gas water heater, and then the controls failed. It would be better to take Bosch than this defect. Although, they say, the quality of Bosch has also deteriorated, so it is not clear what is better now.

Advantages:

• Compactness - the device is really small and neat, smaller than its Soviet counterpart, which went to the landfill;
• The geyser is equipped with a fan, so interruptions in draft do not affect its operation;
• It shows the temperature on the screen - you couldn’t imagine anything better, but previously you had to set the optimal temperature for the water by touch.

Flaws:

• Weak heat exchanger - leaked quickly;
• I had to invite a specialist to install it - otherwise they threatened to void the warranty;
• Lack of resistance to voltage surges - I had to buy an additional stabilizer;
• We thought that it would work quietly, but that was not the case - it makes noise.

We spent almost 11 thousand, but received some kind of Chinese counterfeit. I advise you to better analyze reviews of geysers in the future so as not to buy a pig in a poke.

Mikhail, 38 years old

The store told us that it is best to buy geysers from domestic producers– they say, they are inexpensive, easy to repair, and work reliably. They recommended taking the VPG-6E model, and we decided to listen to the advice. This is not to say that the unit works without failures. Firstly, 10 months after purchase it began to drip - the heat exchanger had leaked. And secondly, without a display it turned out to be not very convenient to control the temperature. Cousin, who works as a heating engineering specialist, said that it is better not to buy such equipment in the future - it is no different from Chinese heaters.

Advantages:

• “Iron” ignition activation when opening the tap;
• Small thickness of the case - only 14 cm;
• Easy to install yourself - the device weighs only 6 kg.

Not the most successful model, there are better ones.

Vladimir, 56 years old

I work in a small store as a storekeeper, and at the same time I am responsible for the supply of equipment. We have Chinese geysers on sale, as well as their approximate analogues from the Neva brand. Lately we have been abandoning the cheapest models; people often complain about them, so we carry them less and less. The exception is the good model Neva Lux 5514. It has increased productivity, weight is 12 kg - this indicates the use of high-quality components and a good heat exchanger (without saving on metal). As far as I know, complaints about this column are rare, even though many components are made in China.

Advantages:

• Good work at two water points - productivity is 14 l/min;
• Batteries last a long time, but it’s better to take good alkaline batteries rather than junk from stores with fixed prices;
• Can heat water to very high high temperatures, but it is best to limit it to reasonable limits so as not to injure the heat exchanger.

Flaws:

• In order for the heat exchanger in the geyser to last as long as possible, it is best to place it in front of it good filter. Otherwise, it quickly becomes clogged or leaks form;
• The model is noisy - it’s amazing how this can be achieved in our time;
• I heard from people that the speaker can burn a little immediately after turning it on - it’s not very clear why this happens.

If you want to purchase a domestic geyser, it is best to choose this model.

Innocent, 46 years old

If you want to provide hot water to two water points at once, it is best to choose a gas water heater with good performance. I recommend the Bosch WR 15-2P model for purchase. Indeed, Bosch used to be much better, but compared to what the Chinese are doing, this speaker is simply a standard. It has certain disadvantages, which I will definitely tell you about. But it is a leader in terms of price/quality/functionality ratio. I recommend her to all my clients, rarely anyone is dissatisfied.

Advantages:

• Does not make noise - this is a truly low-noise model. It ignites smoothly, without rattling or plaster falling off the ceiling;
• The case does not overheat - therefore, the speaker can be used in the most intensive mode without fear of its failure;
• It won’t scald your hands when you turn it on – here I’ll note a smooth increase in temperature, without jumps.

Flaws:

• If the heat exchanger deteriorates, repairs will be expensive - this is the main disadvantage. In order for the geyser to last a long time, it is better to study the quality of the water and ensure its filtration;
• The gas unit is weak - it is better not to adjust the temperature using the cold water knob, otherwise it may fail;
• There is no automatic flame modulation - if it were here, it would be an ideal gas water heater.

Dmitry, 38 years old

When I arrived at the store, I immediately indicated to the salesperson that I wanted the model with maximum performance. The seller said that it is best to take a powerful device from Rinnai. I had to wait two weeks for delivery, since the model was not in stock - they rarely take it. But the wait was worth it, as this is truly the best gas water heater I have ever encountered. The water can heat up to a record +70 degrees, the combustion chamber is closed, so I didn’t need a chimney. There are smart electronics on board that monitor overheating and safety. You can safely leave a gas water heater in an unheated house, as it has protection against freezing.

Advantages:

• Convenient digital controls - there are no outdated antediluvian knobs;
• Capacity up to 24 l/min - if you open two taps, the temperature and pressure will not change;
• There is a gas leak monitoring system;
• Convenient temperature control using the display.

Flaws:

• I had to call a specialist for installation, otherwise they would not provide a guarantee. Soon it will probably be impossible to change a light bulb yourself;
• Expensive – I had to pay 35 thousand rubles for a gas water heater.

There are almost no shortcomings, the device works at 5+.

Igor, 41 years old

I devoted almost 15 years of my life to repairing gas equipment, including water heaters. Not long ago I got a job at an installation company, we do heating in houses, we install equipment for heating and hot water preparation. A couple of months ago, equipment was installed in a small low-rise residential complex. Boilers for autonomous heating were installed in each townhouse; Zanussi GWH 10 Fonte gas water heaters were used to organize hot water supply. This scheme ensures maximum maintainability and increases the reliability of heating and water supply systems - these are not double-circuit units that plague you with heat exchanger breakdowns.

Advantages:

• There were a lot of townhouses, but during the entire period of operation of the speakers, we received a complaint from only one homeowner - his heat exchanger was leaking. Well, factory defects always have a right to exist.
• Affordable price - initially it was planned to purchase Chinese gas water heaters, but then they would definitely have bombarded us with rotten eggs and tomatoes. Therefore, we decided that it was better to go with Zanussi;
• There is no problem with frequently leaking heat exchangers, despite their low cost. This is partly due to good water;
• If something goes wrong due to small things, then repairing a geyser will not cost half of its cost - you can’t imagine anything better;

Flaws:

• Accurate ignition, without pops.
• When the pressure changes, it responds with a change in temperature - but this is quite expected;
• It is not recommended to adjust the temperature with a mixer; it is better to do this on the gas water heater itself - this way it goes out less, although I consider this a disadvantage. After all, that’s why it’s a faucet, so that you can adjust the temperature yourself without jumping out of the bathroom into the kitchen;

For the correct operation of a geyser, it is best to purchase good, expensive batteries - this results in extra costs, but the ignition works more stably and for a long time.

It is better to take a gas water heater from Zanussi than from an unnamed Chinese manufacturer.

Video The geyser is one of the most convenient devices for those who do not want to depend on the whims of public utilities, as well as for those who want to achieve with a high level of comfort. Constant improvement of speakers makes them increasingly popular among almost all segments of the population.

In many multi-apartment buildings, the problem of providing comfortable water procedures falls on the shoulders of the residents. This fully applies to owners of private houses. There are three ways to solve the problem - install a boiler, instantaneous electric heater or geyser. The third option is the most economical. Let's consider which geyser is better, and expert reviews will help in this matter.

Before you figure out which gas water heater to choose, let's figure out how it functions. Geyser is a wall-mounted instantaneous water heater. It is designed to quickly heat water using the energy of combustion of natural or liquefied gas.

Modern speakers They are distinguished by their ease of use due to the partial or complete automation of many mechanisms, but in terms of the operating principle and basic elements they are almost no different from their “predecessors”. The main structural components of the device are:

• pipes - for gas supply, cold water inlet and hot water outlet;
• burners - main and pilot;
• heat exchanger

When you open the hot water tap, a flow of liquid appears at the inlet pipe of the column. In response to this, the gas valve is activated. The fuel begins to flow to the main burner, which is ignited by the pilot burner. The combustion of gas leads to the release of heat, which enters a heat exchanger with a coil - a spiral pipe through which flows cold water. As a result, the liquid is heated and supplied to the water supply.

The air necessary for the combustion process comes from the room through the window. Combustion products are removed under the influence of natural or forced draft through a chimney or shaft. As soon as the water flow stops, the gas valve closes and the column turns off.

Advantages

Gas water heaters have remained in demand for several decades. Their main advantages:

1. Easy to use. This feature does not apply to older devices. But using new modifications comes down to pressing one button.
2. Economical. Heating water with a gas water heater is more profitable in terms of cost savings than using a boiler. In the latter case, energy is spent not only on achieving required temperature, but also to maintain it. And gas is consumed exclusively during the period of time when hot water is needed. In addition, the cost of gas is lower than that of electricity.
3. Comfort. A gas water heater can heat a large number of liquids in a short period of time. It can provide several water points at the same time.
4. Compact size and attractive appearance. The small size makes it easy to find a place to place the speaker. Modern models have fashion design, as well as various additions in the form of drawings on the front panel.
5. Durability, reliability. At correct operation and high-quality performance of the device, it can last for several decades.
6. Safety. Modern speakers are equipped with control systems that are responsible for automatic shutdown in case of various problems.

Features of choice

If there is a problem with how to choose the right gas water heater, you need to pay attention to the following parameters:

• method of removing combustion products;
• power;
• ignition type;
• method of adjusting water temperature.

Method for removing combustion products

The geyser can be equipped with a chimney or work without it. In the first case, combustion products are removed through the pipe by natural draft. Typically, a chimney is inserted into the heater's corrugated hose, which goes out onto the roof of the house. If the question is how to choose a gas water heater for an apartment, then in most cases such devices are not suitable, since modern houses there is no technical possibility of installing a chimney.

Columns of the second type are also called turbocharged. Carbon monoxide is removed under the influence of forced pressure created by a fan. The exhaust is discharged into a vertical or horizontal pipe without natural draft, connected to the column. As a rule, it is brought outside through a hole in the wall.

Turbocharged speakers are suitable in cases where the house does not have a chimney. But they are more expensive than chimney-based devices and rely on electrical power. In addition, you need to ensure that the external outlet routes do not freeze, otherwise the coil may rupture.

Power

When figuring out which geyser is better, in the reviews of experts you can see a recommendation to use Special attention for power. It determines how much water is heated in 1 minute. The device power can fall into one of three ranges:

• 17-20 kW;
• 20-26 kW;
• 26-31 kW.

When choosing a column based on this parameter, you should take two points into account:

• number of water points in the house;
• volume of hot water required daily.

If you need to provide hot water to one point, and there are 1-2 people living in the house, then a device with low power is sufficient. An indicator of 20-26 kW is acceptable for most city apartments. The power of such a column is enough for 2-3 water points and a family of 3-4 people. If you have several bathrooms and your household loves water procedures, you should opt for a heater with high power.

Important: When choosing a column, you should take into account the gas pressure in the system. If it is insufficient, the device will not be able to operate at full capacity. There are devices with a gas reducer that maintains constant pressure.

Ignition type

Depending on how the pilot burner lights up, geysers are divided into devices with a piezoelectric element and electronic ignition. In addition, there are devices whose wick must be lit with a match, but they are rare.

In devices with a piezoelectric element, the igniter ignites as a result of exposure to an electrical discharge with a potential of several kilovolts. As a rule, ignition is carried out once a day by pressing a button on the column panel. Then the “duty” wick burns throughout the day, and the main burner lights up the moment the tap is opened. The disadvantages of such a water heater are the need for easy access to it and constant, albeit insignificant, gas consumption.

The column with electronic ignition is equipped automatic device, emitting a spark that ignites the igniter or immediately the main burner at the moment the tap is opened. Electronic elements are powered by batteries, mains power, or a small hydraulic turbine generator built into the housing. Experts advise choosing a column with a hydraulic turbine if the water pressure in the system is not lower than 0.35 atm.

A “smart” water heater costs more than a column with a piezoelectric element. Its advantages are fully automatic operation and no need for constant burning of the wick.

Adjusting the water temperature

When thinking about how to choose a gas water heater for a private house or apartment, you should consider the method of adjusting the water temperature. There are two aspects to this issue:

• setting the desired temperature;
• maintaining a constant temperature.

The regulator, which allows you to set the water temperature, can work:

• smoothly – the selector knob turns smoothly within the range between the minimum and maximum limits;
• stepwise - you can choose one of three indicators - low, medium or high temperature;
• automatically - the degree of water heating is set using an electronic system.

One of the factors influencing the final water temperature is its pressure in the system. If it is unstable, the temperature will fluctuate. If the burner has a constant power, then you can only adjust the water parameters manually, which is very inconvenient. More comfortable option– burners with modulating power. They adapt to changes in pressure, automatically maintaining the temperature initially selected by the user.

Protective devices

Safety during operation is one of key parameters when choosing a gas water heater. The device should automatically turn off or not turn on at all in case of interruptions in gas, water or lack of combustion. For this purpose, it is equipped with many sensors. The main ones:

1. Ionization and combustion sensors (thermocouple). They are designed to automatically stop the gas supply to the burner when the flame goes out. First, the ionization sensor must operate, and if it fails, the combustion sensor must operate.
2. Traction sensor. It controls the presence of traction. If it is absent or a backflow of combustion products occurs (for example, due to the chimney being blocked by debris), the gas supply is blocked. This mechanism protects home residents from carbon monoxide poisoning.
3. Hydraulic valve that turns off the column when it overheats.
4. Flow sensor. It is responsible for automatically turning on/off the device when opening/closing a hot water tap.
5. Water pressure sensors. Safety valve prevents pipe rupture under increased pressure. Sensor low blood pressure does not allow starting or turns off the column if water is not supplied at all.
6. Gas supply sensor. It blocks the operation of the device when the fuel supply stops. This protects against leaks.

When purchasing a speaker, it is important to make sure that it is equipped with all of the following protective devices. Otherwise, it cannot be called safe for humans.

Operating rules

The service life of a geyser depends not only on the quality of components and assembly accuracy, but also on the correctness of its operation. Basic recommendations:

1. Installation and maintenance of equipment should be trusted to professionals.
2. The heat exchanger must be cleaned regularly.
3. You should not set the outlet water temperature above 40-60°. This leads to accelerated scale formation on the membrane, resulting in reduced column performance.
4. If the water in the system is very hard, then to protect the heater it should be additionally equipped with a system that prevents salt deposits.
5. It is impossible to regulate the temperature of the liquid by opening the tap cold water. Temperature selectors should be used. Otherwise the system will be delayed hot water, steam is formed and overpressure. As a result, water may begin to leak from the heat exchanger.

A geyser is a device capable of providing individual hot water supply in a house or apartment with minimal costs. When choosing a device, it is important to consider its power, safety and operating features. You should not save on buying a water heater, since high-quality automatic devices can provide comfort during water procedures for a long time.
