Comparison
Verdict in brief
The PEG075EID and PEG112EID are adjacent sizes in the current PEG-E gas-fired cast-iron STEAM line — both non-condensing atmospheric boilers with a rear-mounted integral draft hood, probe-type LWCO and pressure controls, rated at 82.2% and 82.4% AFUE. The PEG112EID fires 112 MBH against 75 MBH, printing 70 MBH of net steam (47) over 292 sq ft (195), with 4 cast-iron sections against 3; both use 2" (single) piping risers, both use a 5" vent pipe and a shipping weight of 368 lb against 297 lb.

| Specification | Utica PEG075EID | Utica PEG112EID |
|---|---|---|
| Input | 75 MBH | 112 MBH |
| Heating capacity | 62 MBH | 93 MBH |
| Net AHRI steam rating | 47 MBH | 70 MBH |
| Steam radiation | 195 sq ft | 292 sq ft |
| AFUE | 82.2 % | 82.4 % |
| Cast-iron sections | 3 | 4 |
| Vent pipe size | 5" | 5" |
| Piping risers | 2" (single) | 2" (single) |
| Dimensions (W x H x D) | 10⅞ × 35⅞ × 28⅜ | 14⅛ × 35⅞ × 28⅜ |
| Shipping weight | 297 lb | 368 lb |
Both models are PEG-E gas-fired cast-iron steam boilers — non-condensing, atmospheric chimney venting through a rear-mounted integral draft hood and vent damper, with cast-iron push nipples, stainless steel burners, and a probe-type low water cut-off with pressure high-limit control, pressure gauge and gauge glass. Neither modulates: input is fixed.
The sell-sheet ratings table prints 75 MBH input, 62 MBH heating capacity, 47 MBH net steam over 195 sq ft and 82.2% AFUE on the PEG075EID, against 112 MBH, 93 MBH, 70 MBH over 292 sq ft and 82.4% on the PEG112EID. Net steam ratings use a piping and pickup allowance of 1.333.
The physical step changes the near-boiler piping: both use 2" (single) piping risers, both use a 5" vent pipe, both take ½" NPT gas, and cabinet dimensions move from 10⅞ × 35⅞ × 28⅜ in to 14⅛ × 35⅞ × 28⅜ in with shipping weight from 297 to 368 lb. Steam sizing starts from the connected radiation load, so the heat-loss and radiation survey decides between the two — installation belongs with a licensed contractor.

112 MBH input against 75 MBH, 70 MBH net steam over 292 sq ft against 47 MBH over 195 sq ft, and 4 sections against 3, per the official PEG-E sell sheet.
PEG075EID: 2" (single); PEG112EID: 2" (single), per the IOM near-boiler piping figures. The product page describes single and dual piping riser options depending on boiler size.
No — every PEG-E is a non-condensing cast-iron steam boiler with atmospheric chimney venting, an integral draft hood and a vent damper.
A consultation includes a heat-loss review so the size is right the first time.
