Description
Navien has been pushing the boundaries of efficiency for 25 years. The NPE-240S2 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.
