Navien NPE-180S2 150,000 BTU Condensing Premium Gas Tankless Water Heater


Navien NPE-180S2 150,000 BTU Condensing PremiumGas Tankless Water Heater

Navien has been pushing the boundaries of efficiency for 25 years. The NPE-180S2 is a result of their dedication to providing an effective and green water heating unit. The NPE-180S2 and all Navien models utilize condensing technology which captures additional heat lost by typical water heaters. The Navien NPE-180S2's energy factor is superior to both traditional water heaters and noncondensing tankless models. Reduced vent temperatures due to this condensing technology allow you to use PVC venting, which saves you money and contributes to the ease of installation. The Navien NPE-180S2 has excellent technology for reducing your heating costs and carbon footprint.
