The Neva 4510 geyser is an equipment capable of operating on both liquefied and natural gas. This model is well suited for those who do not have a significant budget for the purchase of such equipment. There are also a lot of reviews on it, and almost all of them are laudatory. It is worth finding out whether it is really possible to purchase reliable and durable equipment for such a low price of $ 150.

Technical characteristics of the geyser Neva 4510

productivity is at the level of 10 liters per minute,
power - 17 kW,
the minimum allowable water pressure in the system is 0.3 bar,
maximum allowable - 6 bar,
auto ignition is used in the gas water heater,
the obtained efficiency level is 84%,
maximum allowable water pressure - 1 MPa,
nominal consumption of natural gas - 1.95 m3 / h,
nominal consumption of liquefied gas - 0.64 m3 / h,
nominal pressure of natural gas 1.3-2.0 kPa,
nominal pressure of liquefied gas - 2.9 kPa,
required chimney diameter: 125 mm.

Due to the ability to work even with the pressure of the supplied water of only 0.15 atmospheres, the column will become a good choice for a house, whose communications have a problem with the supply. However, the manufacturer does not recommend frequent use of the column in adverse conditions.

Advantages of the Neva 4510 geyser

even when the intensity of the incoming water flow changes, the water temperature is maintained in a given mode,
multilevel security system will provide automatic disconnection from the network in case of failures,
digital display,
the heat exchanger is made of copper, without admixture of other metals,
good value for money makes this model a leader in its price segment,
copper built-in heat exchanger,
modern design,
large water passage,
when properly operated, it requires a call of the master only once a year, when carrying out scheduled maintenance.

The geyser itself has earned versatile reviews. On the one hand, at its price, miracles are clearly not worth expecting. On the other hand, during its operation, design flaws are increasingly manifested.

Automation allows the column to turn on only when the tap is opened, the rest of the time it is in "sleep" mode. This saves energy spent on the operation of the column.

Judging by the reviews, not all the positive aspects of the older models were transferred to the Neva 4510 geyser. Despite its constructive simplicity, the range of adjustments is clearly overestimated.

Disadvantages of the Neva 4510 geyser

The gas water heater is sensitive to the quality of the supplied water. It is not uncommon when, when rusty water is supplied from the water pipes, the channels are simply clogged, because of which the working pressure begins to drop. Despite the fact that on the scale each valve has about fifteen positions for adjustment, users notice a different range of adjustments for gas injectors. In fact, only three provisions are mentioned.
Often, the column heats water to an excessively high temperature, which is also typical for storage water heaters. In the main mode, the column heats water up to 45 ° С. At the same time, automatic protection often serves as a certain disadvantage. For example, when simultaneously opening and cold tap, there are cases of activation and automatic shutdown of the column.
When the tap is loosened more than half the advertised low noise level is clearly higher than the values in the brochure. Users note such a strong contrast that in this case, the speaker drowns out even conversation in calm tones, and this is a level of 60 dB. The problem lies in the operation of the radiator itself.

The declared copper in the heat exchanger is more valuable for collectors of precious metals. Scale builds up quickly on the heat exchanger due to hard water. Since copper does not react chemically with most cleaning agents, descaling the heat exchanger is extremely difficult. As the technologists note, the use of stainless steel heating elements would be more expedient.
It is also noted that the gas water heater often operates in a different temperature range. Of course, a contrast shower is good for health, but the truth is not every person likes it, especially if it is compulsory. Complaints about frequent leaks are also common, due to which the gas water heater itself often fails.

On the whole, there is an ambiguous picture. On the one hand, there are many accolades. So laudatory and professionally written that the hired copywriters are suspected. On the other hand, there are many negative reviews about the same design flaws. It seems that the buyer is faced with a difficult task: to trust the reviews, or to buy this model himself and soon join one of the parties.

Advantages and disadvantages

Based on the technical characteristics and reviews about the Neva-4511 gas column, the following advantages can be distinguished:

Modern speaker design.
Acceptable price.
Ease of use.
Small size.
Works practically silently.
The column is equipped with a temperature indicator.
Inexpensive spare parts.
It is convenient to turn the column on and off.
A high-quality security system that meets all the requirements.
Temperature level and water flow can be adjusted.
Availability of service centers. Service and repair is available to everyone.

But the Neva-4511 column also has some disadvantages:

Low efficiency. Foreign manufacturers produce models with a higher efficiency value.
The bandwidth is low. If one tap is turned on in the house, then it is undesirable to turn on the other, since hot water will flow in the first.
The leaving water temperature cannot be controlled. If the water temperature at the inlet rises, then too hot water will flow from the tap.
If the water is of poor quality, then the heat exchanger will quickly become dirty.
To install the column, a dry wall with high-quality thermal insulation is required.
Periodic battery replacement is required.
Not everyone has a gas water heater for a long time. Since the service life is affected by the observance of all the rules of use, as well as the quality of the equipment assembly.

Disadvantages of gas water heaters Vector

Most users are sure that for little money they purchase a super unit that is equipped with all the technical characteristics and functions. However, this is absolutely not the case. It should be understood that due to the use of the most economical version of Chinese spare parts, such a column will not be able to serve for many years, as, for example, similar models of a more expensive price segment. In some cases, after some time, alternative options for replacing components may be needed.

In addition, although the walls of the heat exchanger are made of copper, they have a very thin layer of it, so over time they can burn out, not withstanding high temperatures. As mentioned above, the column turns off only after the water reaches a temperature of 80 degrees. therefore walls become thinner over time

, as a result of this, the device becomes unusable.

In fact, there are as many opinions as there are users. Some owners consider this column to be the best purchase, while others consider the models of this manufacturer not the most successful. In any case, until a person tries to use it on his own, he will not be able to give an objective assessment.

Column ignition

The column can be kindled in different ways:

The most convenient and popular is electronic ignition. Columns with such ignition are slightly more expensive than others. But they are more reliable and economical. Most often, batteries are used as a battery.

In piezo ignition it is necessary to press the button on the panel to ignite the gas. In new models, this method is sometimes used.

In modern models, manual ignition is rarely found. Such columns are practically not produced.

Columns with microturbine ignition are quite expensive. In such models, the current is generated by a hydrodynamic generator that controls the water flow. These columns are easy to use. After opening the tap with water, the gas is ignited automatically. This results in significant gas savings.

Security

Everyone knows that any gas equipment is dangerous. Therefore, for safe use, the gas water heater is equipped with various control sensors. If the fire goes out, the ionisation sensor automatically shuts off the gas supply.

With the help of a heating sensor, the temperature regime of the entire device and heating elements is monitored.

If the ionization sensor stops working, then the additional thermal sensor starts working.

At the moment when the water is drawn, it is necessary to turn on or off the gas supply. For this, a water pressure sensor is used. In modern models, they began to install a temperature change control sensor. In this model of the gas water heater, such sensors are not used.

To control the supply of gas or water to the column, a gas and water pressure sensor is used.

If the pressure rises in the system, the safety valves automatically shut off the gas and water supply.

Advantages of geysers Vector

Gas instantaneous water heaters from the manufacturer in question have a number of visible advantages, thanks to which they began to be widely used by Russian consumers. And first of all, it is an affordable price. Not every person is ready to pay more than 10 thousand rubles for such equipment, and it is not always possible to do without it, living in a private house. In the lineup of gas water heatersVektor
there are devices no more than 4000 rubles, at the same time they are able to solve all universal problems.
Stylish look helps preserve the trendy design of the room

Since the column is available in a universal color scheme, it will not draw attention to itself, and in some cases it may even become a decorative element. In addition, the manufacturer Vector takes care of saving space in the room, so the gas water heater is not large.

In the event that the device fails for any reason, then in any market you can find Chinese-made parts that do not require large financial costs, and will also extend the service life of the column.

At the column convenient control system

... Modern models have two knobs for adjusting the gas supply to the burner and the amount of water flowing through the heat exchanger. Some devices have another switch - between winter / summer modes. In the first program, the burner operates on all sections; in the "Summer" program, some of the sections are switched off. On the case (if there is an electronic display), you can see the set temperature regime of the water.

Possible speaker malfunctions and how they can be eliminated

If you have a minor breakdown, then you can fix it yourself. Here is some of them:

After a short operation, the water heating device turns off. Low thrust is the reason. To do this, it is enough to clean the chimney. And it also does not hurt to check the connection of the gas outlet pipe. In the event of a malfunction, the connection must be sealed;
If water comes out with a temperature over 90 °. To eliminate such a problem, you need to lower the gas consumption, and, on the contrary, increase the water consumption. In this way, the desired inlet temperature can be achieved;
If the column does not start when you open the tap. To do this, you need to replace the batteries or check their installation;
Carbon build-up on the flame detector. It is necessary to clean it;
If the water pressure in the system is weak, then you should contact the utility service;
If there is not enough water, you need to adjust the flow rate;
If scale appears in the heat exchanger or filters are clogged, then it is necessary to clean it;
It is necessary to fully open the taps at the water inlet and outlet if they are partially open;
If, after opening the tap, the column does not start, but there is a spark. In this case, open the gas supply valve;
When you turn it on for the first time or after a long downtime, air often appears in the communications. To solve this problem, you can open the tap for a few seconds, then close and reopen it. This procedure can be carried out several times;
If no spark enters the gas stream. With such a problem, it is necessary to adjust the distance between the burner and the spark plug electrode.

Before using the Neva-4511 geyser, you must carefully study the attached instructions. It describes in detail all possible problems and how to fix them. In more difficult situations, it is necessary to consult a specialist.

The Neva-4511 column is an excellent inexpensive option that is produced in Russia. In addition, it has many positive aspects. For a small family, such a column is perfect.
