NPF700-100U5CH FAQs
What are the advantages of a hydronic forced-air furnace?
One of the quietest furnaces you can buy. The NPF is also energy efficient burning gas at 97% efficiency and using high efficiency electric motors. The NPF is also Ultra-low NOx compliant so it is a good steward for the environment minimizing the emissions that can contribute to ozone and acid rain. The EZ-Nav interface allows the system to be configured quickly and precisely meeting the specific comfort needs of any home.
What is an upflow furnace?
An upflow furnace is one that discharges the conditioned air vertically, out of the top of the unit, into a discharge plenum which connects it to the ductwork which then distributes the conditioned air throughout the home.
How long does a hydro air furnace last?
Same as a traditional residential gas furnace, when properly maintained, atleast 20 years
Does hydronic forced-air heating cause humidity?
The hydro-furnace does not add humidity to the conditioned space.
As a homeowner, if I have an issue with my unit can I call technical support for troubleshooting help?
If you have an issue with your Hydro-furnace, please contact the original installation contractor or you can go to the Navien website (www.navieninc.com) to locate your nearest qualified Navien contractor.
Does Navien have field technicians available to service my hydro-furnace?
