Navien NHB boiler install video on YouTube
An outdated floor-standing heating system makes way for Navien’s new high-tech wall-hung condensing modulating boiler, the NHB, in a video shot during a recent Pennsylvania retrofit. Featuring a most efficient turndown ratio of 15:1, installer Dave Yates of F.W. Behler recommends this product while he fully expects to see an energy consumption reduction of 30% to 50% for his customer.
You can view the video on YouTube or Navien’s NHB website.
