NTI Compass NC110
The NTI Compass NC110 is the 95% AFUE floor-standing Compass at 11 to 110 MBH input — the same 193 lb cabinet as the NC085 with 25 MBH more ceiling for detached homes with an indirect tank.

NTI Compass NC110 in practice
The NC110 lifts the Compass line to an 110 MBH ceiling at 95% AFUE while keeping the 193 lb floor cabinet shared with the NC085. It is heating-only on 1 1/4" NPT CH connections, with domestic hot water from an indirect tank or separate water heater, and carries the same integrated ECM pump and primary/secondary piping as the rest of the platform.
For homes whose heat-loss calculation exceeds the NC085's 85 MBH — or that add recovery demand through an indirect tank — the NC110 adds ceiling with no footprint change, since the Compass cabinet is common across the heating models up to the NC199. Its 11 MBH minimum fire keeps low-load modulation practical in BC's mild climate.
Best suited to
- Detached homes whose load calculation lands between 85 and 110 MBH
- Houses pairing the floor-standing Compass with an indirect tank
- Retrofits wanting a floor-footprint replacement with more headroom than the NC085

Frequently asked questions
How does the NC110 compare with the NC085?
Both are heating-only Compass models in the same 193 lb floor cabinet. The NC110 fires 11 to 110 MBH at 95% AFUE; the NC085 fires 8.5 to 85 MBH at 96%.
Does the NC110 need a wall?
No — the Compass is floor-standing. NTI markets it as dropping into an existing floor-mounted footprint without wall construction or stands.
What are the NC110's venting limits?
2" runs to 100 ft or 3" runs to 150 ft per side, per the NTI Compass product page.
