Utica Boilers · Series
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).
Series facts
85% AFUE as printed on the CuB product page. The heat exchanger is copper and combustion is atmospheric — the design is non-condensing despite the 'modulating' nameplate.
The CuB Series is Utica's modulating gas hot-water boiler family, positioned on the product page for heating-only and combination ('combi') heating and domestic hot water applications, including single-family homes, apartments and multi-family dwellings with individual appliances, and retrofits for high-temperature systems. The page prints 85% AFUE, a COPPER heat exchanger, atmospheric combustion, chimney or horizontal venting and hot-water boiler type; a fan and gas valve modulate between 33% and 100% of capacity, and the advanced controls provide a digital display with temperature indication, diagnostics and status symbols for heating mode, burner on and burner modulation level.
Two configurations are documented: the combination CCB-150 combi, available at 150 MBH with a stainless steel brazed-plate heat exchanger for potable domestic hot water and an additional DHW mode in the control; and the space-heating-only CHB models, available in 100 MBH and 130 MBH with dedicated domestic hot water connections for adding an indirect water heater. Options include an LP gas conversion kit, a horizontal vent termination concentric kit, a floor stand kit, an indirect hot water tank sensor and an outdoor air temperature reset sensor. Utica prints a 10-year limited copper heat exchanger warranty and a 2-year limited parts warranty.
Status note: the CuB page remains live with current documents — the CCB 150 IOM Rev. H, the CHB 100-150 IOM Rev. G, spec sheets, submittals, application guides, user manuals and warranty — but the line does not appear on Utica's category cards, so the utica2 research records it as a legacy listing rather than part of the current catalogue. Despite the 'modulating gas boiler' nameplate, the official 85% AFUE rating with a copper heat exchanger and atmospheric combustion describes a NON-condensing design, and Boilers.ca records it that way. Gas, venting and combustion work belongs with a licensed contractor.

Utica Boilers
The Utica CuB CCB-150 is the combination model of the CuB Series: a copper-heat-exchanger, atmospheric gas boiler firing 50–150 MBH for 130 MBH heating capacity and a 110 MBH net AHRI water rating at 85% AFUE, with a stainless brazed-plate DHW heat exchanger delivering 6.3 GPM at a 40 °F rise.
Utica Boilers
The Utica CuB CHB-100 is a heating-only model of the CuB Series: a copper-heat-exchanger, atmospheric gas boiler firing 31.5–100 MBH for 85 MBH heating capacity and a 73 MBH net AHRI water rating at 85% AFUE, with dedicated connections for an indirect water heater.
Utica Boilers
The Utica CuB CHB-130 is a heating-only model of the CuB Series: a copper-heat-exchanger, atmospheric gas boiler firing 43.5–130 MBH for 110 MBH heating capacity and a 96 MBH net AHRI water rating at 85% AFUE, with dedicated connections for an indirect water heater.

Services for Utica Boilers boilers
No. The official page prints 85% AFUE with a copper heat exchanger and atmospheric combustion — a non-condensing design. The 'modulating gas boiler' title refers to its 33–100% capacity modulation, not to condensing operation.
The CCB-150 combination (combi) model at 150 MBH with a stainless steel brazed-plate domestic hot water heat exchanger, and the heating-only CHB models at 100 MBH and 130 MBH with dedicated DHW connections for an indirect water heater.
The page is live and carries current documents (CCB 150 IOM Rev. H, CHB 100-150 IOM Rev. G), but the line does not appear on Utica's category cards, so it is recorded as a legacy listing — documented and serviceable rather than shown in the current category.
