Navien is a large South Korean corporation, which produces universal, high-quality and reliable gas boilers. Navien devices are characterized by reliability, practicality and functionality. These appliances have an open or closed combustion chamber, their functional part is durable. At the same time their cost is lower, compared to European counterparts.
Navien presents a universal water heating system
Navien Ace gas boilers are not afraid of low gas and water pressure, they are not afraid of voltage drops in the network. The operation of Navien gas boilers is characterized by a long period of operation and economical gas consumption. All Navien gas appliances meet the standards and norms of the Russian Federation and have the appropriate certificates.
Stability of the frost protection system
If the room temperature drops, then the automatic protection system works from freezing. When the water temperature drops, the heating is higher 10 degrees Celsius, the circulating pump is started automatically, resulting in constant circulation of the coolant in the heating system. If the heating water temperature drops to 6 degrees Celsius, the burner is automatically switched on and the coolant is heated to 21 degrees Celsius.
Safety at frequent voltage drops in the network
According to the instructions, voltage can fluctuate within ± 30 percent, due to the operation of the processor protection chip Switched - Mode Power Supply (SMPS). With the operation of the boiler does not stop, which prolongs its period of operation and prevents breakage.
Operating conditions of heating and hot water:
- under the condition of low inlet pressure in the gas pipeline system - stable and safe operation of the Navien Ace gas boiler is possible at a gas pressure of four mbar (40 millimeters of water column);
- under the condition of low inlet water pressure in the water supply system - stable operation of the Navien Ace gas boiler is possible under the condition that the inlet water pressure drops to the value 0,3 requires, what allows you to use this gas device in homes, where the low water pressure in the water supply system, including, where frequent pressure drops in the water supply system.
rational design
Navien gas boilers are small in size and light in weight, they are easy to transport, they are easy to install and there is a possibility of rational use of space. For easy installation, connecting tubes are located on both sides of the device, which greatly simplifies the tying and installation of the Navien Ace gas boiler.
Fuel preheating (KR series)
Fuel viscosity increases at low temperatures, resulting in the effect of paraffinization, what significantly impairs the flammability of diesel fuel and the operation of the Navien gas boiler becomes unstable. This feature is relevant for regions with harsh climates, therefore, Arctic and winter diesel fuel have been created for these conditions.
Navien gas appliances run on any Russian-made diesel fuel, however, the cost of winter or arctic diesel fuel is much higher, than annual, and the use of summer fuel is impossible at low temperatures without preheating.
Heating element, which is built into the burner of the Navien gas unit, before applying fuel to the injector, preheats it, resulting in high-quality fuel spraying and uninterruptible flammability. Due to preheating in Navien Ace gas boilers is the possibility of using inexpensive summer diesel fuel, which leads to significant savings.
construction
1. The heat exchanger is made of stainless steel
Stainless steel is used for the production of the heat exchanger, thus it does not corrode, which significantly extends the life of the Navien Ace boiler.
2. Modern diesel burner
Due to the modern efficient diesel burner low-noise stable operation with the minimum fuel consumption is provided. according to the instructions the burner can run on any diesel fuel, taking into account all types of fuel produced in the Russian Federation.
3. Fuel filter with replaceable cartridges
The fuel supply system is equipped with a filter to clean from unwanted impurities, as a result of which stable operation of the Navien Ace gas boiler is broken. Optional replacement cartridges are included with the Navien.
4. Russified control panel
With the help of a remote fully Russified control panel, equipped with a liquid crystal digital display, is being created the possibility of economical fuel consumption and reduced heating costs, as well as constant maintenance of comfortable temperature in the room thanks to the sensor of room temperature, built-in remote control.
Safety precautions
Safety instructions are provided in each user manual for the Navien boiler, where all the important information for safe use of the device is located. Failure to comply with any instructions may result in death, serious injuries and damage to the operated product.
The following abbreviations and symbols may be found on the Navien Ace boiler or in the instructions:
- OB - heating water;
- GWP - hot water supply;
- HVP - cold water supply;
- triangle, which has an exclamation mark inside - a threat to life, if safety rules are not followed;
- circle crossed out - prohibited actions;
- circle, with an exclamation mark inside - required action.
Navien gas boiler is an excellent alternative to expensive counterparts European production, which is not inferior to them in quality and durability. The main advantage over other European devices is the availability of warranty service.
