Navien America Launches Innovative ASME Approved Condensing Combination Gas Boiler


N


avien America Inc., the pioneer in high efficiency tankless water heaters, introduced its new Condensing Combination wall hung boiler in


response to the rapidly growing demand for a tankless unit that fulfills a combination of heating applications. Navien’s Condensing Combination Boiler is versatile


and ideal for domestic water heating and space-heating applications, including in-floor radiant heating, base- board heating, and fan assistance-air handler heating applications. It also features Navien’s signature condensing technology and uses PVC venting which lowers the cost of installation and simplifies the process significantly. The Combi unit has all the traditional lifestyle benefits of Navien tankless technology and can offer substantial energy savings for end consumers. The Combination Fin-type stainless-steel heat


exchanger, stainless-steel condensing heat exchanger and premixed burner are components that make this product so unique. The Combi unit has an integrated primary and secondary heat exchanger that are made of stainless steel which prevents corrosion and ensures a longer lifespan over copper parts. The Stainless-steel components also maintain temperature consistency even during long periods of use, With the Combi model, Hydronic heating is made possible due to the stainless- steel’s capacity to maintain low and consistent temperature levels and the unit captures as much condensation as possible making it highly efficient. The “combi” unit is green-friendly and utilizes an “ECO” Pre-mixed Burner that generates at least 20% less


CO2 and about 75% less harmful air pollutants such as NOx emission. Also, an Outdoor Sensor can be connected to Navien’s Condensing Combi water heater and the unit can e Circle 19 on reader reply form on page 111


model and we expect it to be very well accepted by contractors, wholesalers and consumers across North America” said Ted Kwak, President of Navien America.


“Navien’s Combination unit uses condensing technology and can fulfill many domestic water heating applications. It is easy to install with the use of PVC venting and cost effective and installers and contractors will appreciate the Combi unit for its versatility.” The Combi unit also has an ASA Control System that


maintains a consistent, comfortable temperature throughout the home at all times which even takes into account the home’s design as well as outside temperatures. The secret to this system involves a built- in thermostat which senses even the slightest temperature changes. The Combi’s space-heating application calculates the amount of heat required based on the difference between the return-water temperature and the indoor temperature, then automatically adjusts and controls the temperature accordingly. Professional contractors can purchase these


innovative, Condensing Combination tankless gas water heaters, along with the rest of the Navien’s product line at major plumbing wholesale houses across the United States and Canada. ;
