One wall-hung cabinet covering both hydronic space heating and domestic hot water is what makes a combi worth specifying — no separate tank, no second flue, and a considerably smaller mechanical footprint. The NCB-190/080H is the mid-small heating output in that family.
Heating output reaches 80,000 BTU/h at 95% AFUE, suiting a wide range of typical homes. The hot water side delivers up to 160,000 BTU/h with a 15:1 turndown and 4.3 GPM at a 37°C rise, so showers hold temperature without the boiler hunting.

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 combi-boiler 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.
