NTI Compass NC110C
The NTI Compass NC110C is the smallest floor-standing Compass combi: space heating at 11 to 110 MBH input plus 2.7 GPM continuous DHW at a 77°F rise, rated 95% AFUE in a 194 lb floor cabinet.

NTI Compass NC110C in practice
The NC110C is the entry combi of the Compass floor line, adding domestic hot water to the platform without a separate tank: NTI rates its continuous DHW at 2.7 GPM for a 77°F temperature rise, alongside an 11 to 110 MBH space-heating input at 95% AFUE. The cabinet weighs 194 lb — 1 lb more than the heating-only NC110 — and keeps the same reversible connections and integrated pump package.
For a compact BC home replacing an old floor-mounted boiler and tank, the NC110C offers one-appliance simplicity on an existing footprint. The practical check is the 2.7 GPM continuous DHW figure against the household's real draws: steady single-shower use fits, while simultaneous multi-bathroom draws point to the NC150C (3.6 GPM) or an indirect-tank design.
Best suited to
- Homes replacing a floor boiler and tank with one floor-standing appliance
- Compact houses whose heating load fits within 110 MBH
- Retrofits where the existing floor footprint and piping orientation are retained

Frequently asked questions
How much hot water does the NC110C deliver?
2.7 GPM continuous at a 77°F rise per the NTI product page. Delivery depends on incoming water temperature, so a site check matters for winter sizing.
Is the NC110C a combi version of the NC110?
Yes. Both heat at 11 to 110 MBH at 95% AFUE; the C adds the domestic hot water function and weighs 194 lb against the NC110's 193 lb.
Does the Compass NC110C need a floor stand?
No. The Compass is a floor-standing cabinet; NTI markets the line as needing no wall construction or stands.
