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 small 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 as low as 0.15 atmospheres, the column will be 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,
a multi-level 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, constructive 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 allows you to save 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 for a situation when, when rusty water is supplied from 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 too high a 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 clearly exceeds 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, it is extremely difficult to descale the heat exchanger. 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.

Lineup of geysers Vector

Speaking about geysers Vector, the following models can be noted.

In the budget price category, Vector gas water heaters are the best option for instantaneous water heaters. They are easy to operate, have a good security system and stylish design. Since not the highest quality Chinese components are used for production (which can significantly reduce the price of this equipment), the service life without repair is not very long. In any case, it will not be difficult to find components for restoring the performance of the gas column.

The VEKTOR geyser is a lightweight and compact water heater, the installation of which will not be a problem in small spaces. Despite their compact size, the speakers are powerful enough to provide two taps.

Gas water heater VEKTOR Production:

The production of dispensers was established in Russia with the participation of the BaltGaz trademark created on the basis of gas water heaters produced at the Leningrad Gas Equipment Plant whose history dates back to 1945. The hallmark of VEKTOR gas water heaters has become an original solution in the design of a glass facing panel in the form of various paintings. A wide palette of paints and color solutions has always found a positive response from buyers.

The VEKTOR geyser met the certification standards of the State Standard of the Russian Federation. The design solutions made it possible to operate efficiently - at an initial pressure of 0.2 bar. The equipment safety concept is based on a multi-level protection system. This approach was supposed to provide the buyer with safe operation.

VECTOR brand products were created for convenience at the lowest cost. In the Russian market, it was probably difficult to find analogues at a cheaper price. The modification of the water heaters had a fairly wide linear range.

Specifications:

However, according to customer reviews, the acceptable price of the Vektor column does not justify the poor quality of the product. And multi-layered protection is constantly failing. It is noted that the columns are an inconvenient collector due to which the mixing chambers become clogged with dust, which cannot be completely cleaned. It is difficult to achieve the desired temperature, the readings on the thermometer are constantly floating up and down.
At times, the column is ignited with a clap, although the burner and heat exchanger are clean. After a short time of operation, it begins to leak, the fittings connections leave much to be desired. The reason for this was the assembly of VEKTOR speakers from cheap Chinese components. Currently, the production of such speakers has been completely discontinued. The VEKTOR gas column has been completely redesigned.

Geyser VEKTOR - new life

Since the column is discontinued, we will not do a detailed review of the models that have sunk into the summer. A new generation of water heaters under the NEVA brand has replaced. The production of NEVA series devices is carried out by the "Armavir Gas Equipment Plant". Which, in turn, is part of the concern of enterprises of the BaltGaz Group.

The most popular models of gas water heaters are the Chinese product - "gas column Vector". Customers from Russia control the orders of this product.

Testing and quality control of gas water heaters is carried out at the factory. All this is done by qualified specialists.

Gas water heater "Vector" is a popular model among consumers in the Russian market. But the reviews about the gas column "Vector" are contradictory.

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.

Main characteristics of model 4510

The geyser "Neva 4510", reviews of which you can read below, has an auto-ignition system. Its weight is 10 kg. There is an indication of inclusion and gas control in the design. The minimum water pressure reaches 0.3 bar. The liquefied gas consumption is 0.77 m3 per hour. As for natural gas, its consumption during the operation of the column will be 1.95 m3 per hour.

Before purchasing a gas column "Neva Lux", it is recommended to read reviews about it. You can find them below. But considering the characteristics, you will understand that the described model does not have a remote control. It runs on liquefied gas and has an open combustion chamber. For ease of use, the manufacturer has provided the design with a heating indication.

Safety

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.

Gas column device

The general principle of operation and the device are typical for all models of instantaneous gas water heaters. Propane enters the column through a branch pipe. A valve is installed in the branch pipe that regulates the gas supply. Water is supplied to the adjacent pipe in the gas column. A control valve and a sensor are installed in the branch pipe. When the sensor is triggered, gas enters the burner through the branch pipe. The gas ignites in the burner.

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

From a piezoelectric element.
From batteries.
From a hydrogenerator.

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

The diaphragm in the block rises under the pressure of water and exerts pressure on the stem, which turns on the gas. If there is a draft, then the gas burner turns on. Water flows through the tank and heats up.

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.

Main characteristics of model 6011

If you liked the 6011 column model, then you should pay attention to its main characteristics, among the main ones it is necessary to highlight the nominal power. It is 21 kW. The equipment weighs 11 kg, it has an auto-ignition.

The advantages include indication of switching on and gas control. The minimum water pressure is 0.15 bar. When connecting, take into account the diameter of the chimney, it is 125 mm. There is a display and indication of heating in this equipment. The design is based on an open combustion chamber. This flow-through device operates on liquefied gas and does not have a control panel, which is important for many consumers, which is justified, because this makes it easier to control the column. In one minute, using the "Neva" gas column, reviews of which are presented in the article, you can get 11 liters of warm water.

Model reviews

The geyser "Neva Lux 5514", reviews of which will be presented below, according to consumers, is a safe equipment to use. It is easy to operate and has auto-ignition, which can be called an important advantage. There is no constantly burning ignition flame in the device, this indicates the durability and safety of the column, which is very popular with customers.

This model is quite often chosen by buyers for the reason that it has a moderate cost, but the power is quite high. It is noteworthy that the equipment has a security system, as well as an ionization flame control sensor. The device is capable of operating at the lowest possible water pressure within 0.3 bar, which is very important for problematic systems.
