This Korean heating equipment manufacturer offers both floor-standing and wall-mounted boilers on the domestic consumer market. Navien sells a wide range of boiler equipment, including those powered by natural gas.
The manufacturer has mastered the production of condensing boilers, atmospheric gas generators, and closed-chamber hot water heaters.
Popularity of Navien Gas Boilers
Today, Navien Korean gas boilers have become widely popular among the population due to the following advantages:
- An attractive pricing policy: under the Korean brand, customers purchase boilers assembled using Western European technology, but at a significantly lower price;
- Boiler equipment can easily be converted to operate with liquefied fuel (propane-butane mixture);
- Gas hot water heaters are adapted to low pressure in main pipelines, maintaining combustion even at 4 mbar;
- Dual-circuit models provide a hot water circuit with low cold water pressure at the boiler inlet;
- the electronic control unit is resistant to voltage fluctuations, and an SMPS chip provides reliable protection.
Navien Dual-Circuit Korean Gas Boilers
Products in this segment include models with thermal outputs ranging from 16 to 35 kW, allowing the boilers to heat areas up to 350 square meters and produce 8-15 liters of hot water per minute from the secondary circuit (DHW). Dual-circuit models are in demand due to their design features, which affect the equipment’s MTBF. For example, a Korean manufacturer makes the heat exchangers of its boilers from high-alloy steel. Stainless steel lasts significantly longer than copper alloys for a number of reasons:
- Alloy steel is chemically inert to salts present in water;
- The stainless steel surface of the water jacket is less prone to salt deposits, which reduce heat transfer efficiency;
- steel lasts significantly longer under flame exposure.
When purchasing a Navien dual-circuit boiler, experts https://domioffis.com/ recommend considering that its primary function is to produce hot water for domestic use. Therefore, using this type of unit in commercial establishments (cafes, cafeterias) with intensive hot water consumption is not recommended. Prolonged operation of the water heater in DHW mode will negatively impact the temperature in the heated spaces.
