Occupies 80% less space than a traditional floor standing boiler and tank water heater.
Stainless steel heat exchangers for hydronic heating are warranted for 10 years. They resist corrosion longer than copper or aluminum heat exchangers.
The sophisticated gas flow control system provides a high turn down ratio, reducing energy waste and excessive boiler cycling and enhances temperature control for DHW.
For extraordinarily large domestic hot water flow demand, the NCB can be cascaded with an NPE unit.
Navien Combi boiler is appliances in one. It provides sufficient heat for your hydronic radiator system and your hot water for your taps and showers, without sacrificing quality.
Flow technology is an advanced system designed to provide the most comfortable and seamless delivery of hot water on the market. The two key components on all “A” model condensing tankless water heaters are, internal insulated buffer tank and a recirculation pump. Since Navien is the only tankless manufacturer to provide you with these premium features you never have to worry about the “cold water sandwich” phenomenon that affects many other tankless water heaters.
Accuserv replaced my propane boiler and hot water tank with a combination boiler/tankless natural gas system. The project was done professionally and carefully. I am very happy with the end result! Aaron and Jared were courteous, knowledgeable and professional, paying attention to all the details. I would recommend Accuserv for anyone who needs a furnace and/or hot water system replacement. I also enrolled in the monthly service plan as I feel confident my new system is in the right hands for years to come. Thanks Aaron!
Old heater/boiler failed due to usual builders’ shotty corner cutting practices. With a 3 week old newborn this couldnt be a worse timing! Long story short, Aaron, James and Josh were able to push their appointments and accommodate to my urgent needs. 2 days later I now have a new efficient and functional heater/boiler unit! Couldn’t appreciate more for the prompt turnaround and friendly customer service guys!
