The NHB-110H is a heating-only boiler — no domestic hot water module — which is the right answer whenever hot water is already handled by a tank, an indirect cylinder, or a separate tankless unit. Dropping the DHW side keeps the cabinet small and the price down.
It runs at up to 95% AFUE with a 15:1 turndown, so it modulates closely to the load instead of cycling. The cabinet measures 17.3″ wide, 23.8″ high, and 12.8″ deep and weighs 80 pounds, which makes it manageable in a tight mechanical closet. Forced draft direct venting accepts a range of vent materials and lengths.

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 heating 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.
