The NPE-180S2 is the size most single-family homes actually need. It modulates between 15,000 and 150,000 BTU/h at a 0.96 UEF, which puts it in ENERGY STAR territory while keeping the purchase price below the 199,000 BTU models.
Up to 8.4 GPM at a 35°F rise suits a house with two or three bathrooms where a couple of fixtures may run together. Dual stainless steel heat exchangers give the unit its condensing efficiency and its service life; the wall-hung cabinet installs indoors or outdoors.

Before you order
Check the published Navien documentation for this model against the property: heat loss or hot water demand, gas supply and meter capacity, gas line sizing, venting route and materials, condensate disposal, electrical supply, and clearances. A condensing tankless water heater that is oversized for the load is not a safer choice — it cycles more and modulates less.
Grabllo sells equipment only. Gas, venting, electrical, and hydronic work must be carried out by an appropriately licensed professional, with any permits the local jurisdiction requires. Manufacturer warranty terms are set by Navien and normally depend on qualified installation and registration.
