A little about the Neva company

The company has existed for more than half a century, and initially it was a state-owned enterprise called Gazapparat. This enterprise specialized, as the name suggests, in the production of household gas equipment: water heaters, various heaters, and also produced heating boilers.

At the end of the 90s, the enterprise became the property of the Baltic Gas Company concern, while maintaining production facilities in the city of St. Petersburg. It was under the management of this giant that the company, one might say, received a second life and began to develop rapidly.

New types of Neva gas boilers, equipped with modern automation, saw the light. Errors and shortcomings of the first models were taken into account, and the equipment was seriously improved. As a result, today the domestic consumer has the opportunity to purchase a reliable single-circuit or double-circuit luxury series boiler at an affordable price. And the company is seriously thinking about entering the global sales market.

Main types of Neva Lux boilers

Models and technical characteristics of boilers
There are 2 basic modifications in the model range - Turbo and Lux. Turbo boilers are energy dependent. For their uninterrupted operation, an uninterruptible power supply, a 220 V network, and an electric generator are required.

The Neva Lux boiler is controlled by a thermostat. The automation operates completely autonomously and reduces fuel consumption. As a result of automatic regulation, the control unit independently adjusts the temperature regime depending on the degree of heating of the room.

Double-circuit gas boiler

Traditionally, the company produces models for main gas. But for those who only have liquefied liquid in stock, several models are available.

Double-circuit gas boilers are designed for heating and hot water supply. Owners of apartment buildings can refuse utility services and provide hot water themselves. It will be cheaper. The water temperature can be adjusted.

Single-circuit gas boiler

Models with one thermal circuit are smaller in size than dual-circuit ones. Their operation is much simpler. They only maintain the temperature of the coolant in the heating system. The most important of the current off-season maintenance is cleaning the working chamber and chimney from carbon deposits. Annual maintenance will prevent the occurrence of significant problems during operation.

Overview of the boiler line

Model 8224 Turbo is suitable for heating an apartment up to 250 sq. m.
m The Lux model line has been updated with a new Turbo modification. This is a separate series of equipment. It was made taking into account the advantages and disadvantages of the previous modification.

Widely used models:

• For heating an apartment or house, a single-circuit wall-mounted boiler is suitable. Instead of a water circuit, you can install an indirect heating boiler. The modulation burner allows you to effectively save fuel. The 8618 boiler is attractive due to its simplicity of design and low cost. It does not contain volatile, complex electronics. Compact dimensions allow installation in small spaces. The circulation pump in the boiler makes it possible to connect to existing heating systems. It is possible to connect an indirect heating boiler, a forced smoke removal fan, or a room thermostat.
• The 7218 and 8224 Lux series are very popular among dual-circuit models. Modern automation monitors the temperature in the hot water supply and at the same time energizes the heated floor outlets. To reduce heating costs, a separate thermostat is installed to monitor the room temperature - it turns on the boiler only when the set temperature drops. Neva Lux 7218 is suitable for heating an area of ​​180 sq.m. The bithermic heat exchanger reduces equipment costs while maintaining user-specific features. The efficiency is 90%. The device can be converted to liquefied gas. It has a closed combustion chamber. The coolant temperature is 30-85 degrees. An electronic safety unit with permanent flame monitoring constantly checks the burner.
• Neva Lux 8224 heats 250 sq. m. of residential premises. Water cooling of the combustion chamber doubles the operating life. The microprocessor maintains the temperature level of the working environment with an accuracy of 1 degree. A copper heat exchanger is used for the heating circuit; a stainless steel one is used for the hot water supply. The ability to connect a computer has been added to the control to simplify diagnostics and equipment configuration. The digital display displays self-diagnosis information with parameters and errors.

The operation of the boiler is based on the “set it and forget it” principle. Once you set the parameters, you don't have to worry even when you turn off the power. During a long business trip or trip, the equipment is set to minimum mode and saves gas. When the gas supply stops, the boiler switches to circulation mode and circulates water around the circuit, preventing it from freezing.
