Heating gas boiler navien: design and technical characteristics of wall-mounted and floor-mounted units + owner reviews

Boiler range

The very first Navien gas boiler that entered the domestic markets received reserved reviews from consumers. People noted that the internal elements of the boiler are not reliable enough and are prone to leaks. Taking into account user complaints, the company corrected the shortcomings and today Navien gas boilers are an example of durability and trouble-free operation.

In view of this, the number of consumers of products from the Korean brand has increased, and the manufacturer decided to expand the linear range of products. If a few years ago domestic buyers could only purchase a Navien Ace gas boiler, the operating instructions for which regulated the use of the heating device, today the following options are available on the market - these are atmospheric, condensing and turbocharged boilers.

Atmospheric series

The main difference between the boilers of this series is the special design of the open gas combustion chamber. The series brought together boilers adapted to difficult working conditions. For example, the Navien Atmo atmospheric gas boiler can operate with low gas pressure in the pipelines and minimal coolant pressure in the circuit.

In the line of the Korean brand, Navien atmospheric gas boilers, reviews of which are worth reading before purchasing, are presented in models of various capacities.

Depending on the heating needs, the consumer can install a device with a rated power of 13, 16, 20 and 24 kW in the home.

The specificity of this boiler lies in the possibility of remote control of temperature conditions and operating time, achieved by equipping the boiler with a remote control panel. It is worth understanding that the device will work quite effectively in the heating system if the owner follows certain recommendations - do not fill the circuit with antifreeze, monitor the pressure level in the system, etc.

The operating characteristics of the boiler are presented as follows:

• maximum water heating temperature - 80°C;
• Efficiency - 86%;
• working pressure – up to 3 bar.

Turbocharged series

This series combines three product categories. These are boilers under the Deluxe, Prime and Smart TOK brands. Each group contains heaters of varying power, designed to heat rooms with a certain area. For example, the Navien Deluxe Coaxial 24k gas boiler, reviews of which are positive, is a wall-mounted heater designed to heat 240 square meters. m.

If the Navien Deluxe 24 kW gas boiler, reviews of which will help you form an opinion about the efficiency of operation, is too powerful for the consumer, he can pay attention to turbocharged boilers with a minimum rated power. This could be a Navien 16 kW gas boiler, the price of which will be more affordable and can vary in the range of $250-300. Such a boiler will provide heating for a house up to 120 square meters. m.

The Navien turbocharged gas boiler, the instructions for which contain information for consumers, has a number of design differences. It is equipped with a closed combustion chamber into which air is supplied by a forced method. For this purpose, a fan is used, the performance of which is regulated by an integrated controller.

Street air from outside the building, using a coaxial chimney and a fan, is forced into a combustion chamber with sealed walls. Thanks to the use of forced air injection technology, the Korean developer managed to achieve excellent efficiency for all turbocharged boilers. So, the minimum value of this coefficient is 92%.

As for the configuration features, any Navien wall-mounted gas boiler with a forced air injection system is equipped with an expansion membrane, a built-in pump to create pressure within the network, as well as a second heat exchanger. The last element expands the functionality of the boiler and allows the use of a second circuit to supply hot water used for domestic needs.

Condensation series

Heating devices of this series are characterized by the highest operating efficiency. These include the Navien wall-mounted gas boiler with the abbreviations NCN and NCB. The design feature is that the heat exchanger is designed by the manufacturer with the ability to collect not only active, but also passive heat. A stainless steel heat exchanger installed in a Navien gas boiler, reviews of which speak of high efficiency, removes the latent heat generated when gas burns.

Unlike boilers of the turbocharged and atmospheric series, the condensing gas boiler Navien 24 kW, the price of which can reach one thousand dollars, will ensure rational consumption of resources and open up reserves for savings in the future. Despite the fact that the cost of the boiler is high, installing it in a heating system will allow you to achieve an extremely high efficiency of 98% and reduce monthly bills for natural gas consumption.

Basic errors and their elimination

Gas boiler units are equipped with a good diagnostic system, which scans the boiler operating parameters every minute and, if they are violated, issues a coded signal to the operating panel to eliminate the malfunction:

Basic failure codes for Navien gas boilers:

1. E01 - overheating of the coolant in the boiler. Insufficient water circulation through the device; it is necessary to check the operation of the pump, the presence of leaks and blockages in the heat exchanger. If the latter is detected, before eliminating the error, it is recommended to flush the heat exchanger from scale using the technology specified by the manufacturer.
2. E02 - error 02, low coolant pressure in the heating circuit. Check for leaks in heating networks and, if necessary, recharge the circuit.
3. E03 - problems in the boiler electric ignition system. It is necessary to check the presence of power in the system, the presence of pressure and the electrode for the presence of a spark.
