Gas boilers Neva: technical specifications, range overview and maintenance

Currently, many people install gas boilers in their homes. This product is widely represented in the stores of heating equipment. Today we will talk about such devices from the company Neva.

Neva gas boilers are single-circuit or double-circuit equipment that has an open or closed combustion chamber. The temperature regulator is built in each of such devices. It controls the temperature of the coolant.

The operation of such units can be generated with a thermostat.that will provide an opportunity to accurately set the temperature. The burner of this unit has automatic equipment used to control the flame.

Each Neva boiler is equipped with a pressure gauge. (a device for measuring the pressure of gas and liquid). Install it on the device panel. With a significant increase in temperature regime increases the pressure in the system. Heating devices of this company can work stably even with low pressure of water and gas.

On such gas boilers there is a screen with which you can set the desired temperature mode. Thanks to the display, the operation of blocks and nodes is monitored. Attached is a special control panel. In one set with the device itself there is an expansion tank, a circulation pump and a detailed diagram, which contains a complete description of the installation of the device.

Gas boilers have several important advantages.

• Modern design. These boilers have a beautiful and neat appearance, as evidenced by many consumer reviews.
• Low price. According to most experts, this technology for heating will be affordable for almost anyone.
• Good performance.Such units can work stably even with too low pressure of gas and water.
• Security. This equipment is equipped with a multi-level security system.
• Ease of management. To set the desired mode, you just need to select the temperature you need on the monitor using the remote control.
• The possibility of heating for two wings. Gas boilers Neva can be used to heat a house with two branches.

Despite this list of positive qualities, Neva gas boilers have some drawbacks.

• The presence of noise. Often, during operation, such an apparatus emits extraneous sounds.
• The possibility of breaking the buttons of the screen. Some users noted that after a small amount of time after purchase, a breakdown of the button, which is responsible for switching the temperature mode, occurred in these units. After that, it had to additionally buy, as well as set for a separate price.

Neva currently produces many different models and series of gas boilers. So, one of the most popular equipment lines is BaltGaz.

It includes the following instances:

• Neva 14 Turbo;
• Neva 18 Turbo;
• Neva 11 Turbo;
• Neva 24 Turbo;

Convection boiler Neva 24 Turbo has a closed combustion chamber. This model is wall. It is designed for single phase network. This copy has a double-circuit heat exchanger of bithermic type.

Coolant temperature in the model Neva 24 Turbo is 20-80. Included with the device itself is an expansion tank. Its volume reaches 6 liters. Built-in circular pump also comes in a set with the device. The heated area with such a device can be 240 sq. M.

The next model is the Neva 11 Turbo. It boasts a high level of efficiency. It is almost 92%. The combustion chamber, as in the previous sample, is closed. By means of this unit it is possible to establish system of a heat-insulated floor. The heated area of ​​this equipment is 110 square meters. The dimensions of this specimen are standard - 420x700x270 mm.

Another example of such a series of boilers is the Neva 14 Turbo. It also has a high level of efficiency, which is more than 90%. Like the previous device, this equipment is often used to connect a floor heating system. The combustion chamber of the unit is closed.The heated area is only 140 sq. M.

The gas Neva 18 Turbo device, as well as other models of the BaltGaz line, has a closed combustion chamber, an expansion tank (its volume is 6 liters) and an additional circulation pump. Its dimensions reach 420x700x270 mm. The heated surface area is 180 sq. M.

Another popular collection of gas boilers of the company is Lux. It includes several models. So, one of them is Lux 7023. This sample is used for space heating of no more than 240 sq. M.

Model units Neva Lux 7023 is often used to create an autonomous heating system. The heat generator at such a heating apparatus has a special coaxial heat exchanger, which provides rapid heating of the water. Removal of all harmful gases in such devices is due to the exhaust fan.

Another model of this series is the Neva Lux 7218. As a rule, this sample is installed in buildings with an area of ​​less than 180 sq. M. Its heat exchanger is bithermic. It allows to significantly reduce the cost of the heat generator.

A copy of the Neva Lux 7224 has the ignition, which is turned on automatically.To make the modulation of the flame in this apparatus, there is an electronic type of control. The closed combustion chamber for this model is manufactured with forced ventilation.

Copies of the Neva Lux 8023, 8029 are of the same type. They are often used to heat large industrial buildings, because with such a powerful device you can easily heat an area of ​​up to 300 sq m. In it, each individual circuit has its own heat exchanger, but the main one is considered to be the heating circuit.

The water supply circuit is secondary. It is made of stainless steel, has a plastic appearance. This prevents scale build up on the surface of the product. Elimination of excess gas emissions is carried out thanks to the action of an exhaust fan.

Neva Lux 8224, 8230 and 8235 devices have similar characteristics and properties. These two-circuit devices are often used not only to heat ordinary spaces, but also to rapidly warm water resources. The last two digits in the numerical index of each sample indicate their power (the Neva Lux 8224 has a power rating of 24 kW, for the Neva Lux 8230 it reaches 30 kW, and for the Neva Lux 8235 the power rating is 35 kW).

To increase the service life, these models are produced with a special water cooling system for heat exchangers. Their generators are equipped with a special hydraulic unit. In addition, inside these elements are ultra-modern electronic circuit boards.

A copy of the Neva Lux 8520 has a capacity of 20 kW and is capable of heating rooms on a scale of no more than 200 square meters. It has two heat exchangers at once (the primary one is in the heating circuit, the secondary plate element is located in the hot water circuit). Such elements of the boiler are made of stainless steel. It does not allow scale accumulate on the details.

The Neva Lux 8618 device is designed for space heating on a scale of 30-180 sq m. Its efficiency is almost 90%. According to many experts, the device has the highest level of efficiency.

The device Neva Lux 8624 is equipped with an open version of the combustion chamber. The special system of water cooling is built in it. Also in the production of this model has been improved electronic system. Thus, it became possible to use the remote control at a distance, as well as the possibility of stable operation with the connection of a personal computer or an outdoor sensor.

In one set with a heating device is the instruction manual. However, many experts believe that the management of Neva devices is simple, despite the functionality.

On the control panel of the boiler there are two regulators. One of them controls the heating of water, and the other - the temperature of the coolant. If you set a mark to “0” for any of these elements, it will turn off and the heating will stop. It is very convenient in the summer, when the home does not need heating.

If you want to remove the initial settings or simply restart the unit, then you need to press the button, which is located near the temperature fixers.

Having reached the set temperature, the boiler will automatically shut off. This unit also has a function that ensures that the equipment operates at a minimum temperature level. It will not allow the heating system to freeze. As a rule, it is used in the case when the owners of the dwelling leave for a long time from their dwelling.

Sometimes Neva gas appliances encounter some malfunctions and also require repairs. In the event of a breakdown, error codes will be displayed on the device monitor. Their readings allow to detect the defect.

Error codes may be different. Reading the code “01” may mean that the boiler does not turn on / does not heat for the following reasons:

• ignition failure;
• automatic ignition contamination;
• loss of gas supply;
• violation of the supply voltage;

Error code "02" is associated with boiler failure due to overheating of the coolant.

This may occur for the following reasons:

• the appearance of an airlock in the circuit;
• pump breakdown;
• overheating sensor malfunction;
• filter contamination;
• breakdown of the regulator responsible for the gas supply;

Error code “03” means no traction.

This may occur due to:

• flue pollution;
• breakage of the pump or automatic valve;
• defect in the fan;

Error code “04” indicates a too low pressure level in the circuit.

This is due to:

• the formation of an airlock;
• failure of the pressure sensor;
• in cases when water is not fed;

Error code "05" indicates a malfunction of the temperature sensor in the heating system.

The reasons for this may be:

• short circuit of the sensor circuit;
• open circuit of this mechanism;

Error “06” indicates the breakdown of the temperature sensor in the water supply system.

It can occur for the following reasons:

• short circuit between the electronic board and the sensor itself;
• sensor breakage.

Spare parts for Neva boilers can be found in specialized stores.

Most often, consumers have to buy the following parts for replacement:

• jet thread;
• ignition transformer;
• pressure gauge;
• the electronic board;
• ignition candle;
• pressure meter;
