Navien NR-180 Natural Gas Tankless Hot Water Heater – You’ll stop planning your mornings and evenings around your hot water heater and set your own schedule, thanks to the Navien NR-180-. The 98% thermal efficiency of the Navien NR-180- condensing technology stems from Navien’s unique condensing design which incorporates two innovative stainless steel heat exchangers to achieve optimum heating value from every cubic foot. The Navien NR-180 has a stainless steel secondary heat exchanger system that recaptures residual heat from flue gases to pre-heat incoming ground water, which then circulates to the primary stainless steel heat exchanger.

Features:

  • Durable, Cold Rolled Carbon steel exterior.
  • Increased safety due to dual microprocessors controlling vital functions.
