Comparison
Verdict in brief
The FTVN085 and FTVN110 are the two smallest heating-only FTVN boilers and share the same 107 lb wall-hung cabinet, connections and venting. The 085 is the only FTVN rated 96% AFUE and fires down to 8.5 MBH; the 110 adds 25 MBH of ceiling at 95% AFUE, so the choice is the calculated heat loss, not floor area.

| Specification | NTI Trinity FTVN085 | NTI Trinity FTVN110 |
|---|---|---|
| Input, minimum | 8.5 MBH | 11 MBH |
| Input, maximum | 85 MBH | 110 MBH |
| Efficiency (AFUE) | 96 % | 95 % |
| Turndown ratio | up to 10:1 | up to 10:1 |
| Weight | 107 lb | 107 lb |
| Max. equivalent vent length, 2" | 100 ft | 100 ft |
| Max. equivalent vent length, 3" | 150 ft | 150 ft |
| CH water connections | 1 1/4" NPT | 1 1/4" NPT |
| Domestic hot water | Heating-only; pair with an indirect tank or separate water heater | Heating-only; pair with an indirect tank or separate water heater |
Both boilers are wall-hung, heating-only condensing units on the same FTVN platform with the same 107 lb weight, the same 1 1/4" NPT CH connections, and the same venting terms — 2" runs to 100 ft or 3" runs to 150 ft per side. NTI rates the FTVN085 at 96% AFUE and the FTVN110 at 95%.
The firing ranges tell the sizing story: the 085 runs 8.5 to 85 MBH and the 110 runs 11 to 110 MBH. In a well-insulated Lower Mainland home the 085's lower minimum fire tracks mild shoulder-season demand more closely; the 110's advantage appears only when the calculated load or indirect-tank recovery needs more than 85 MBH.
Both are heating-only, so domestic hot water comes from an indirect tank or separate water heater on either model, and neither has an installation advantage in weight or venting. The deciding input is the room-by-room heat-loss calculation: under about 85 MBH the 96% AFUE 085 is the better match, and beyond it the 110 earns its place.
NTI Boilers
The NTI Trinity FTVN085 is the entry point of the FTVN wall-hung condensing family: 8.5 to 85 MBH input at 96% AFUE — the only FTVN rated 96% — in a 107 lb heating-only boiler that also accepts 2" venting to 100 ft for retrofit-friendly runs.
NTI Boilers
The NTI Trinity FTVN110 is the 95% AFUE mid-size heating-only member of the FTVN wall-hung family, firing 11 to 110 MBH in the same 107 lb cabinet as the FTVN085, with 2" venting to 100 ft or 3" to 150 ft per side.
The FTVN085 is rated 96% AFUE and the FTVN110 95%, per NTI's product table — the 085 is the only 96% model in the FTVN line.
Yes. Both weigh 107 lb with the same cabinet, connections and venting; only the firing range (85 vs 110 MBH) and the AFUE rating differ.
When the heat-loss calculation plus hot-water recovery demand more than 85 MBH on a design day. Extra input without a matching load just raises the minimum fire the boiler idles at.
A consultation includes a heat-loss review so the size is right the first time.
