The external cladding is made of metal-plastic. Three layers - primer, galvanization and enamel - reliably protect the boiler from corrosion. They feature improved control panels.

Features of operation

Before you start using Neva Lux, read the manufacturer's instructions. Yes, the boiler is easy to use, but following basic rules will help extend its service life and protect your home from unexpected problems.

On the outer cover of the housing there are two regulators - for heating and domestic hot water. Setting to “zero” means excluding the circuit from operation. Nearby is a reset button.

The operating algorithm of Neva Lux is based on the “switch on and forget” principle. It is enough to set the temperature once, and its parameters will not change under any circumstances.

If the electricity goes out, the mode will be restored automatically when it appears.

The control program includes an economical mode, which allows you not to turn off the heater during short-term departures. It is possible to program several days in advance. The remote control provides additional convenience to the user.

When gas supply stops, to prevent defrosting of the heating system in winter, a mode is provided to prevent freezing of the coolant. In this case, water circulates through the system when the burner is not working.

Neva Lux control panel

Connecting external temperature sensors makes it easier to control the temperature. The sensor is installed in the room farthest from the heater. If the air temperature in it drops below the programmed one, the boiler will turn on (burner) and restore the parameter. It is allowed to install 2-3 sensors simultaneously in different places.

An outdoor temperature sensor also makes the task easier, but its inclusion in the circuit is not recommended due to various types of interference in the form of solar heating, wind, or air with high/low humidity. Such a sensor is installed in proven places that eliminate or minimize the impact of “harmful” factors.

Installation and connection

Before you begin installing and connecting the Neva Lux boiler, think over and sketch out a diagram. The project determines where and how the unit will be inserted, taking into account subsequent piping, and also creates a connection diagram to the electrical network.

The diagram itself will be useful in the future when replacing or repairing the unit. You can install and connect the Neva Lux boiler yourself. There is nothing complicated there. The main thing is to comply with the operating conditions set out in the manufacturer's instructions. But it’s better to trust the professionals. Thanks to their experience and special knowledge, they will accurately determine the required list of strapping elements and carry out the work at the proper level.

On average, the installation process takes 3-4 hours. This is an approximate time. Installing additional thermostats and connecting to the control system may take longer.

Neva Lux boilers are easy to install because they are ready-to-use safe units.

Possible faults

The more complex the equipment, the greater the likelihood of it failing. This is especially true for the electronics included in the control system. Despite the fact that Neva Lux heating boilers are considered extremely reliable, some types of malfunctions cannot be avoided. More often for reasons not related to the equipment itself. These include:

• Low gas or water pressure in the system;
• Breakage and attenuation of the flame;
• Mechanical breakdowns.

The built-in self-diagnosis system displays an error code on the display, which is identified by the table on the last page of the instructions. If there is no warranty, you can fix some simple malfunctions yourself, but it is still better to contact the manufacturer’s customer support service or directly to the service center.

Conclusion

Having studied the characteristics and properties of Neva Lux boilers, we conclude that these gas units are in no way inferior to imported analogues and even surpass them in a number of indicators, for example, cost. At the same time, the units are equipped with imported components, which equalizes the functionality.

The video shows a presentation of Neva Lux gas wall heaters:

Do not forget about the high maintainability of Russian equipment and an extensive network of service centers. This is one of the decisive factors in the popularity of Neva Lux boilers.

One more point - two circuits. If you install such a unit, then nothing else will be needed. The boiler will provide an apartment, house or cottage with heat and hot water without additional costs in the form of an indirect heating tank, etc.

There are no problems with repairs or maintenance either. Spare parts are sold in stores in any region.

Removing the Neva Lux cladding

The only weak point of Neva Lux heating boilers is their dependence on energy. Despite all the convenience of electronic control, a simple shutdown of the light makes them inoperable.

And the problem with our power grids is unstable operation. Voltage surges can lead to failure of the electronic board - the brain of the unit. The problem is solved by using a generator and a voltage stabilization system - UPS.

Russian wall-mounted gas double-circuit boilers Neva provide consumers with maximum comfort when switching to autonomous heating and hot water supply. This equipment is intended for use in multi-apartment residential premises and country houses. For the production of boilers, modern materials are used, as well as high-quality components from the best European suppliers. The company's designers conduct a constant scientific research, testing prototypes of new models at the Gazapparat pilot plant before launching into mass production. Thanks to this, it is possible to correct all the shortcomings, improve the manufacturability of production and, which is important for gas equipment, increase the degree of its reliability.
The domestic manufacturer BaltGaz has implemented two design options in Neva Lux gas double-circuit boilers. Thus, in the boilers of the 72 series, as well as in the BaltGaz 18 DBF boiler, a single bithermal heat exchanger is installed to work with heating and hot water circuits. This decision made it possible to reduce production costs, which had a positive effect on the pricing of these products. In addition, the products of the 72 series provide precise temperature control with a tolerance of 1 0 C. The models of the 82 and 86 series use a traditional layout with two heat exchangers - copper for the heating circuit and plate for the hot water supply circuit. The entire line of double-circuit boilers, with the exception of the Nevalux-8624 model, is equipped with a closed combustion chamber.
In addition to the above, Nevalux gas double-circuit boilers are distinguished by thermal performance and minor design details:

• Nevalux-7211 - thermal power 11 kW, bithermal heat exchanger, maximum heating area - 110 m2
