Navien™ has been pushing the boundaries of efficiency for 25 years. The NPE-210S2 and all Navien™ models utilize condensing technology which captures additional heat lost by typical water heaters. Its energy factor is superior to traditional water heaters and non-condensing tankless models. Reduced vent temperatures due to this condensing technology allow you to use PVC venting, which saves you money and improves the ease of installation. The Navien™ tankless water heater has excellent technology for reducing your heating costs and carbon footprint.
