Brand hub
Utica Boilers is an American boiler manufacturer whose official site runs a French-Canadian distributor page naming Morden National (519-627-0791) as the Canadian contact. Its current catalogue centres on the Oneida Series (condensing CO combis and CH central-heat boilers at up to 95.2% AFUE) and the cast-iron mid-efficiency lines: MGB-K and MGC Series 4 water boilers (84% AFUE, both tagged 'Available in Canada') plus the PEG-E/PEG-F gas steam boilers and the induced-draft SVB Series 4. Boilers.ca documents these at model level; the older MAC/MAH, SSC and UB90 condensing pages carry legacy or archived status, and the CuB, UB95M-200 and MGB Series II/MGC Series pages are live-with-archived or unlisted legacy listings.

Utica Boilers publishes its product catalogues from uticaboilers.com, with pages for condensing gas boilers, gas boilers, condensing combi boilers, oil boilers and related heating products. Its French-language distributor page ('Trouvez un distributeur') directs Canadian distributor enquiries to Morden National by email (customerservice@mordennational.com) or telephone (519) 627-0791, which is why Boilers.ca records Utica's canadianStatus as available while its product pages themselves remain US-market catalogues.
Checked on September 8, 2026, Utica's current condensing and combi catalogue centres on the Oneida Series: the CO (Combi) residential combi in three sizes up to 200,000 BTU/hr input and the CH (Central Heat) residential boiler in five sizes up to 180,000 BTU/hr, rated up to 95.2% AFUE with up to 10:1 turndown, plus commercial CH-299/399/499 sizes on a separate page. Boilers.ca documents the Oneida CO and CH residential models at model level under the Oneida (CO/CH) series record. The older condensing pages — MAC/MAH with MACF/MAHF floor versions (all '(While supplies last)', archived documents), the SSC wall-hung boiler and the UCS-240/380 units — remain live with legacy status, and Boilers.ca does not model them as current.
Naming note for owners and contractors: on the official site the MGC (Series 3/4) and MGB-K gas boilers are non-condensing cast-iron models (chimney-vented, around 84% AFUE); the 'MGC Series II / MGB Series II' names that appear in older references belong to a legacy archived page for earlier non-condensing cast-iron units, not to condensing equipment. The official Gas Boilers category page (checked September 9, 2026) lists the MGB-K, MGC Series 4, SVB Series 4, PEG-E and PEG-F as Current, with 'Available in Canada' tags on the MGB-K and MGC Series 4. The CuB is a copper-heat-exchanger, 85% AFUE atmospheric boiler whose page stays live with current documents but is absent from the category cards, and the UB95M-200 and MGB Series II/MGC Series pages print 'Sorry, There are no current documents for this product!' with archived-only literature. Service and replacement guidance for an installed Utica boiler should come from a licensed contractor or a Utica distributor, and any fault display should be read against the documentation for the specific unit.
Series
Each series hub lists its models, verified specifications, manuals and documented alerts.
Utica's condensing gas boiler category, as titled on uticaboilers.com, now centres on the Oneida Series: the Oneida CO residential combi and Oneida CH central-heat models rated up to 95.2% AFUE with up to 10:1 turndown. Older condensing pages — the MAC/MAH wall units with MACF/MAHF floor versions, the SSC wall-hung boiler and the UCS-240/380 units — are carried with 'while supplies last'/archived-document status, and the MGC/MGB nameplates belong to Utica's non-condensing cast-iron gas models, not condensing lines.
The Oneida Series is Utica's current residential combi/condensing line: the CO (Combi) models — CO-90/150/200, producing domestic hot water up to 5.1 GPM — and the CH (Central Heat) heating-only models CH-80 through CH-180, all wall-hung on a stainless steel water-tube heat exchanger at 95.2% AFUE with up to 10:1 turndown. The commercial CH-299/399/499 sizes (95.1–95.6% as printed) are documented by Utica but not modelled here.
The MAC/MAH family is Utica's wall-hung 'AI' condensing platform — combis MAC-115/150/205 and central-heating models MAH-75/100/125/165 (there is no MAH-205) — on 316L stainless steel heat exchangers at 95% AFUE. Both official pages print a '(While supplies last)' badge with an empty 'Current Documents' tab, so Boilers.ca records the line as discontinued (sell-through).
The SSC is Utica's wall-hung condensing boiler on the patented 316L/444 stainless steel fin-coil heat exchanger (US Patent 10,012,413): six sizes UBSSC-050 through UBSSC-299 at 95.0% AFUE with a 5:1 turndown ratio, built-in primary/secondary manifold piping and pump, built-in probe-type LWCO and 150 psi MAWP. The product page stays live with current documents (IOM Rev. G) but the SSC sits outside Utica's current condensing category cards.
The UB90 Series 4 is Utica's compact floor-standing condensing boiler line: three sizes UB90-50/75/100 at 90% AFUE on a cast aluminum heat exchanger with HSI ignition and a Hydrolevel combination high-limit/LWCO control with boiler water temperature reset. The product page is live with current documents (IOM Rev. F), so Boilers.ca records the series as current.
The UB90-200 Series II is Utica's larger 90% AFUE condensing boiler line: sizes covering 125, 150, 175 and 200 MBH on the cast aluminum monoblock heat exchanger with the Fuel Smart Hydrostat control (temperature limit, LWCO and boiler reset in one control). Its product page prints 'Sorry, There are no current documents for this product!', so Boilers.ca records the series as discontinued.
The MGB-K ('MGB Series') is Utica's current mid-efficiency cast-iron water boiler line: seven atmospheric chimney-vented sizes from 59 to 235 MBH at 84% AFUE, a dry-leg cast-iron heat exchanger, Hydrolevel control with built-in low water cut-off, and a 20-year non-prorated residential warranty. It is one of only two cast-iron Utica lines the official category page tags 'Available in Canada'.
The MGC Series 4 is Utica's current two-size cast-iron water boiler line — MGC-8D and MGC-9D at 262 and 299 MBH, 84.0% AFUE — built for chimney venting with a Hydrolevel FuelSmart control, integral draft diverter and automatic vent damper. It is the second of the two cast-iron lines the official category page tags 'Available in Canada'.
The PEG-E is Utica's current gas-fired cast-iron STEAM boiler line: seven sizes from 75 to 299 MBH at 82.2–83.4% AFUE, atmospheric chimney venting through a rear-mounted integral draft hood and vent damper, 2" single or dual piping risers depending on boiler size, probe-type LWCO with pressure controls, and a 12-year non-prorated residential warranty plus 5-year parts.
The PEG-F is Utica's current gas-fired cast-iron STEAM boiler line: seven sizes from 75 to 299 MBH at 82.0–82.7% AFUE, atmospheric chimney venting through a front-mounted integral draft hood and vent damper, 2½" NPT supply and return connections with two tappings each, electronic low water cut-off with a ¾" probe, and a 12-year non-prorated residential warranty plus 5-year parts.
The SVB Series 4 is Utica's current induced-draft cast-iron water boiler line: five sell-sheet sizes SVB-2 through SVB-6 from 42.5 to 187.5 MBH at 84.0–84.4% AFUE, ventable through a chimney or sidewall, with a Honeywell high-limit/electronic-ignition control, titanium burners and a 20-year non-prorated residential warranty.
The CuB Series is Utica's modulating gas hot-water boiler family on a COPPER heat exchanger: the CCB-150 combi and the heating-only CHB-130/CHB-100, at 85% AFUE with atmospheric combustion and chimney or horizontal venting. The official page is live with current documents but the line is absent from Utica's category cards, so it is recorded as a legacy listing (documented and serviceable, not shown in the current category).
The UB95M-200 is Utica's archived modulating condensing gas boiler: 92.5% AFUE, infinitely modulating from 80 to 200 MBH on a cast-aluminium monoblock heat exchanger, sealed combustion and direct venting in 3" PVC to 100 ft. The page's Current Documents tab prints 'Sorry, There are no current documents for this product!', so it is recorded as discontinued.
The MGB Series II / MGC Series is Utica's legacy non-condensing cast-iron water boiler line: nine sizes from 50 to 299 MBH with efficiencies up to 83.9% AFUE, chimney venting, a Hydrolevel FuelSmart control and an integral draft hood with automatic vent damper. The page prints 'Sorry, There are no current documents for this product!', so it is recorded as discontinued (superseded in the current catalogue by the MGB-K and MGC Series 4 records).
