NTI Trinity TFTN110
The NTI Trinity TFTN110 is the 95% AFUE wall-hung TFTN between the 085 and the 150: 11 to 110 MBH input in the same 107 lb cabinet as the TFTN085, with 2" venting to 100 ft or 3" to 150 ft.

Input is gas energy consumed; output is heat delivered. Never size from input alone.
NTI Trinity TFTN110 in practice
The TFTN110 adds 25 MBH of ceiling to the TFTN085's range without changing the cabinet: both weigh 107 lb with water and share the same 19 7/8 by 34 1/8 by 17 1/4 inch dimensions. It is rated 95% AFUE, heating-only, and connects on 1 1/4" NPT CH pipe with 3/4" NPT gas.
Its 11 MBH minimum fire keeps mild-weather modulation close to the 085's behaviour while the extra ceiling absorbs higher design-day loads and indirect-tank recovery. For a typical Lower Mainland detached house whose heat-loss calculation lands above 85 MBH, the TFTN110 is often the first size that genuinely fits.
Best suited to
- Detached homes whose heat-loss calculation exceeds the TFTN085's 85 MBH
- Houses adding an indirect tank that raises the recovery load
- Projects wanting the TFTN family's compact cabinet with more headroom
