The NPF in action
"If you're coming from a furnace retrofit background and have installed many furnace replacements, putting this in is no different. In fact, I found it way easier because I'm not messing around with dozens of little dip switches."
Brandon Farr, Farr Mechanical
"With the variable capacity on this particular furnace, the NPF, it's extremely quiet. Sometimes it's hard to even tell it's operating. The homeowner mentioned several times after the fact that he can't believe how quiet it is."

"Setting up the @navieninc NPF has never been easier with the “Setup Wizard” 🧙🏻♂️
Many of you may be familiar with this since the upgrade to the on-demand units. The NPF includes many of the same settings with the addition of water fill and airflow features."

"Having the flexibility to run my gas or condensate on either side of the unit is a great feature, and the set up wizard makes for an easy install!
Not to mention how quiet the unit was when it was operating!."
