Despite the fact that in most new apartments in our time hot water is supplied from the central city boiler room, flowing gas water heaters - columns are still relevant. This is especially true for apartments and houses built back in Soviet times: "Khrushchev", "Stalinok" and "Brezhnevok".

Today we will talk about the most common brand on the market - "Neva" from the St. Petersburg company "Baltgaz", and specifically, about gas column Neva 4511, reviews of which are very different, due to the fact that this model is very popular in Russia and abroad.

We will analyze its internal structure, technical specifications and reviews, design features, compare the dimensions, according to the operating instructions, the pros and cons of working, as well as the prices for the Neva 4511 gas water heater, if you plan to buy it.

Features of the Neva 4511 geyser model

Geyser Neva 4511 is a typical modern gas instantaneous water heater. Despite the fact that the company "" is located in St. Petersburg, the apparatus is now being assembled in the city of Armavir Krasnodar Territory. All components and spare parts for this model are made in Russia or China.

Geyser "Neva 4511"

The ignition of this model is automatic, i.e. there is no need to press any buttons, move levers and wait. All you have to do is turn on the faucet hot water in the kitchen or bathroom, and the speaker will turn on automatically. When the faucet is closed, it will turn itself off. Automatic ignition of the burner is achieved by two batteries - batteries ("finger type", type LR 20).

Batteries are installed at the bottom of the device in a special box. Replacement of batteries for the speaker is done by yourself, and this does not affect its 2-year warranty. Their service life varies, as a rule, from one to six months, depending on the manufacturer. For example, Duracell or Energizer batteries will last longer than lesser known Chinese brands.

On the front panel of the Neva-4511 column there is a viewing window and two control knobs. The one marked in blue is responsible for the water pressure, and the red one sets the temperature we need. A digital display is installed between these two handles, which shows the water temperature at the outlet of the geyser.

The numbers in the model 4511 tell us the following: 45 is a series of columns, 11 is the capacity in l / min. In practice, this performance is quite enough for one point of water intake, and this is either a bathroom or a kitchen. If you plan to use hot water both in the kitchen and in the bathroom, then it is recommended to buy a Neva gas water heater of higher power, with a capacity of 13-14 l / min.

The case of this model is painted with enamel and is available in two color solutions:

- white;
- dark gray (silver).

This does not affect the operation of the device, its functions, equipment and characteristics, but, depending on the color, there will be a slightly different price for a geyser, “silver” is sold, as a rule, a little more expensive than white.

Today we reviewed the most popular gas flow-through water heater in Russia - geyser Neva 4511. The reviews left by the owners on the Internet are very different for this model. Let's watch the video.

We only tried to give our subjective assessment, having analyzed the internal structure, technical characteristics, thanks to the instruction manual and sales experience of this model. The price of this geyser as of 2016 is about 9500-10000 rubles.

The NEVA 4511 gas water heater is a compact water heater with a rated power of 21 kW. This indicator is quite enough to provide apartments and country houses of various sizes with hot coolant.

The NEVA 4511 geyser is a budget and rather compact technique that is convenient and easy to use. The flame of the burner is ignited by batteries. The built-in LCD display informs the user about the key operating parameters of the unit. The design provides for the presence of a water cooling system for the combustion chamber. The modest dimensions of the unit make the speaker invisible in any room, which can be considered as an additional plus.

The device of the NEVA 4511 gas column is quite simple, but at the same time, modern technical achievements in matters of efficiency and safety are not alien to it. This model is produced in accordance with domestic and international requirements for equipment of this kind. This indicates that the manufacturer takes a responsible approach to the design of water heating equipment, taking care of both the consumer and its reputation in the international market.

Speaking about the device of the gas column NEVA 4511, it should be noted that the device is designed for convenient operation. The technique starts automatically when the hot water tap is opened and fades out when the user turns off the tap. With an inexpensive and reliable column NEVA series 4511, you can forget about a burning wick, which can become a serious hazard. The fact that the column is ignited by batteries ensures the durability of the main components and extends the life of the unit as a whole.

Model Features

Let's single out a number of advantages with which this column is able to please a potential buyer:

Compactness and ergonomics. The dimensions of the unit are very modest and amount to 565x290x221 mm. At the same time, the entire design is designed in the best ergonomic standards - a convenient control panel and a minimalistic design are the characteristic features of the model.
High operational qualities. The design of the NEVA 4511 geyser took place taking into account the fact that the equipment will work mainly in the difficult conditions of the Russian climate. Because of this, it was made hardy, strong, durable and high-performance. In addition, model 4511 is adapted to work in conditions of low pressure in the water supply system, which can be considered an important plus for users from our country, where interruptions of this kind happen quite often.
Safety and reliability. The unit is equipped with a flame control sensor, which reduces the risk of an unforeseen accident hundreds of times.

disadvantages

Obviously, any domestic water heating equipment has a number of disadvantages. In this regard, the NEVA 4511 model is also far from ideal. With a rated power of 21 kW, it produces up to 11 liters of hot water per minute.

Experts are sure that the technique will not cope with its work if water is taken from two points at the same time. For example, washing dishes when someone in the household is taking a bath will not be easy. The power of the unit is not enough to provide two draw-off points with enough hot water. In addition, the design does not provide for a system of smooth modulation of the flame, which cannot be said about more modern columns.

If you do not need such a powerful unit, and operational know-how is not so important to you, the NEVA 4511 gas water heater will be the best choice for you in terms of price, quality and performance parameters.

Repair

Very often on the network you can find requests like "geyser NEVA 4511 do-it-yourself repair." That is why below will be given typical malfunctions and methods for their self-elimination.

Column does not light up

If the column does not ignite, there can be many reasons for this. Among them:

Lack of draft in the ventilation system. The problem is solved by cleaning the ventilation duct.
Problems with the power supply (batteries are dead). The problem is solved by replacing the power element.
Low water pressure in the water supply system. You can independently wash the filters, clean the column from combustion products and replace the membrane on the water unit. If the problem persists, contact the utility company with appropriate inquiries about the cause of the low pressure in the system.
Incorrect balance between cold and hot water. In this case, you need to adjust the temperature of the coolant produced by the column so that you do not have to mix cold and hot water.

The column turns on with characteristic pops

As a rule, the reason for this is that the ventilation is clogged, the batteries are discharged, the gas is supplied too intensively, or the jet is clogged. In all these cases, it is recommended to consult a specialist. On your own, you can replace the batteries or clean the ventilation ducts.

Water heating is inefficient

If the column turns on, but it does not heat the water to the desired temperature, there may be several reasons for this. Firstly, your equipment may not meet your needs in terms of power parameters. Secondly, if the column is clogged, it loses performance, and this must be taken into account. You can adjust the hot coolant supply valve and call a specialist from the service center who will clean the equipment.

conclusions

The fact that the repair of the NEVA 4511 gas column can be done by hand makes this model a very attractive unit for the Russian buyer. At the same time, the column is inexpensive, has been functioning for decades and does not require special care during operation. Being a universal water heater of domestic production, NEVA 4511 is ideal for operation in Russian houses and apartments.

Buyers say:

Geyser Neva 4511 gets good reviews: Most buyers focus on affordable price and good quality product.

“The parents, having decided to change the column at home, consulted the seller and purchased the domestic Neva 4511. Since they are pensioners, the low cost of the water heater suited them perfectly. Using, they are very happy, the device works without problems, it does not take up much space, decent power. Recommend to all my family and friends."

Sveta Seliverstova, Moscow.

“Having tested this unit, I can highlight the advantages: automation, a copper radiator. The disadvantages include: often you need to change the batteries, every 2-3 months, it is better to put alkaline ones (they are more expensive, but will last longer); wires stick out from under the bottom; components made in China. If it turns off after heating, then it is necessary to replace the draft sensor. I turned it 180 0 and set it up. After that, the warm air from the burner does not get on it, everything is fine.

Igor, Voronezh.

“I like the model 4511 that there is a temperature indicator, temperature and pressure adjustments, compact dimensions, low price. I didn’t like the work, which sometimes makes noise, the throughput is low, the water temperature depends on the pressure. ”

Mikhail Granyuk, Korolev.

“The sizes are small, it works quietly, there is no wick. Made in Russia, and the parts are most likely Chinese. Sometimes there are pops when turned on, for 5 months of use it has become a little louder to work. But when compared with what was before, it works almost silently. When the second tap is opened, the pressure drops very much.

Marina Azhar, Rostov-on-Don.

“I installed it myself for a shower in the country. Be sure to check all details before installation. Most nuts are simply slid onto connectors. We've been using it for over a year. At first it worked well, though there was uneven heating. With a weak gas flow, it warms up for a long time. If the gas is turned on strongly, it quickly heats up and turns off due to overheating. Moreover, a strong flow of water is needed, with a weak one it does not turn on. After a month and a half of work, the solenoid valve broke. Changed. After wintering in a dry room, in the new season it began to work normally. After a couple of weeks, pops began to be heard. Changed the batteries. And again, after a couple of weeks, the solenoid valve broke down.

Andrey Shishparenok, Moscow.

“I chose a column for a long time, I stopped at Neva 4511. I have been using it for more than two years. There are no complaints. The batteries are still the same. Some begin to complain about cotton. I don't care, I can't hear it at all in the bathroom. Disadvantage: the water pressure affects, the less, the hotter. I guess it's normal."

Valery, St. Petersburg.
