Despite the fact that the networks of housing and communal services are constantly being upgraded, the quality of the services they provide currently leaves much to be desired.
Need to use
This is especially true for hot water supply. In order to solve this problem, you need to purchase a gas column. However, you must first consider all the parameters that you need to pay attention to. Modern manufacturers offer for sale a wide range of devices, models of which differ in their own operational characteristics and technical features. However, all geysers can be divided into storage and flow.
Description of flowing gas columns
The Neva gas column, a review of which will be presented in the article, can be flowing. This design has a compact size due to the lack of a hot water tank and a small gas burner. You can install it in a small room with natural good ventilation. Such units have low performance, to connect several points of water intake to the hot water supply system, you need to purchase a device that has great power. Such speakers are most often purchased by owners of urban apartments.
Characteristics of storage gas columns
Cumulative geyser "Neva", a review of which will allow you to make a choice, can be cumulative. A similar device has an impressive size. The volume of the tank can vary from 50 to 500 liters. To use hot water, it will not be necessary to operate the appliance each time. The tank has effective thermal insulation, which allows you to save heat for a long period. The devices have heat exchangers that are more efficient. Among the main shortcomings, significant dimensions can be distinguished, which forces homeowners to install devices in basements, special boiler rooms or in attics.
If you will purchase the Neva-4511 storage gas column, then you should expect that the device has a significant weight in a tank filled with water. This involves the preparation of a concrete base. It is more expedient to operate such heaters in private houses and cottages, where there are several points of water intake.
Description of geysers by productivity
If you visited a store with the aim of acquiring a gas water heater, you can find out that productivity is sometimes indicated in kilowatts or liters per minute. If you want to know this indicator, then you need to look at a special plate located on the column body. Sometimes the manufacturer mentions a figure in the passport of the device. Most often, performance is indicated in liters per minute. If there is a need to determine the column power, then the number of water intake points, i.e. the number of mixers, should be taken into account. Before you buy a Neva gas column, a review of which will allow you to decide on the choice of device, you should consider that one mixer is capable of letting about 7 liters of water per minute. If we assume that the column will be installed in an apartment in which there are two faucets in the kitchen and in the bathroom, then for comfortable simultaneous use of hot water you need equipment with a capacity of 13 liters per minute.
Product characteristics depending on water pressure
Neva gas columns, the characteristics of which are described in the article, should be used at a specific water pressure. In this case, experts advise paying attention to two parameters, among them the minimum pressure at which the device will turn on, as well as the maximum pressure, the last of which is able to withstand the heat exchanger. If we are talking about a flowing water heater, then the minimum pressure is very important, since this parameter will depend on whether the device can turn on. This is especially important for owners of houses that were built a long time ago, since the systems in them are very worn out, and the pressure is too small. It is best if this indicator does not exceed the figures of 0.15 bar. If you will be purchasing a Neva-Lux column, then the maximum pressure that it can withstand is also important. This is due to the fact that the water supply system is characterized by water hammer. This leads to a short-term increase in pressure in the water supply system, which, in turn, causes a rupture of the coolant of the device. Experts advise you to purchase a device whose maximum pressure varies from 11 to 12 bar.
Reviews of columns with different types of ignition
The Neva gas column, reviews of which will be useful to read before visiting the store, may have a different type of ignition. If you want to save, you will have to prefer less technically advanced devices that include a manual kind of ignition. It is carried out by pressing a button and bringing the flame to the soldering iron. If the column is in an inaccessible place, then this technique can be called not only uncomfortable, but also unsafe. Users claim that after starting the wick continues to burn, which can not be called economical. The Neva-4511 gas column has piezo ignition, this option provides for the presence of an electromechanical match, which is integrated into the system. Activation will occur at the touch of a button, however, some users refuse this option, since control occurs with a minimum of electronic components. Most modern speakers have an electric ignition system. An automatic geyser may have its own ignition system, which is divided into volatile and non-volatile. In the first case, when the power is turned off, the column will stop working.
Power Modulation Reviews
The Neva Lux 5514 gas column has power modulation, which, according to users, is a very convenient functionality. With it, it will be possible to adjust the flame intensity in the heat exchanger, which depends on the pressure of cold water. This device allows you to use water of a certain temperature, and it will not depend on the inclusion of water by neighbors. According to users, with the help of power modulation it is possible to significantly reduce gas consumption and increase the comfort of using hot water supply. Among other things, you can protect your loved ones and yourself from getting thermal burns.
Characteristics of columns by type of heat exchangers
The Neva gas column, the installation instructions of which must be attached by the manufacturer, can have different types of heat exchangers. At the heart of the latter are most often highly refined copper, steel, or plain copper. Steel heat exchangers have a low cost and are resistant to corrosion. Models equipped with such elements have an impressive weight, but are very reliable. The Neva gas column, the price of which can vary depending on the heat exchanger, is also supplied with highly purified copper elements. Such a material is similar to that made of steel, but its heat transfer is much higher. This provides a higher level of performance. Simple copper in the device due to the presence of impurities gives uneven heating and the possibility of damage to the tank. However, you can count on the fact that such models will be the most budget. The Neva gas column, the price of which is 9,000 rubles, can be purchased in the store of the corresponding goods.
