Comparison
Verdict in brief
The INN 1350N is the largest Innovation: 1,350 MBH input and 96% certified efficiency against the 1060N's 1,060 MBH and 95%, with turndown up to 27:1 versus 21:1, 11 GPH maximum condensate flow versus 8 GPH, 19.9 gallons of water versus 22.0 and 50 lb more dry weight.

| Specification | AERCO Innovation INN 1060N | AERCO Innovation INN 1350N |
|---|---|---|
| Input | 1,060 MBH | 1,350 MBH |
| Certified efficiency (DOE 10 CFR Part 431) | 95 % | 96 % |
| Turndown ratio (up to) | 21:1 | 27:1 |
| Gas connection (natural gas) | 1.5" NPT male | 1.5" NPT male |
| Water inlet and outlet | 2" NPT male | 2" NPT male |
| Maximum continuous water flow | 50 GPM | 50 GPM |
| Maximum condensate flow | 8 GPH | 11 GPH |
| Water volume | 22 gal | 19.9 gal |
| Weight, installed (dry / wet) | 1000 / 1190 lb | 1050 / 1222 lb |
| Shipping weight | 1,100 lb | 1,150 lb |
Both are DHW-only condensing units with the same connections (2" NPT water, 1.5" NPT gas) and 6" flue and air intake; neither offers the 4" vent option. The 1350N is the line's efficiency leader at 96% certified (DOE 10 CFR Part 431), one point above the 1060N.
Turndown rises to 27:1 on the 1350N against 21:1 on the 1060N, the deepest in the Innovation line, and condensate production climbs to 11 GPH versus 8 GPH.
The larger unit carries slightly less water volume (19.9 vs 22.0 gal) and weighs more: 1,050 lb dry / 1,222 lb wet and 1,150 lb shipping against 1,000 / 1,190 and 1,100 lb. For plants near the 1,000 MBH load line, the 1060N is often the better match; the 1350N is for genuine peak demand.
