Utica CuB CHB-130
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.

Utica CuB CHB-130 in practice
The CuB CHB-130 is a space-heating-only model of Utica's CuB Series, documented on the live CuB product page and in the CHB submittal Rev. D. Its sea-level ratings table prints 43.5–130 MBH input, 110 MBH heating capacity, a 96 MBH net AHRI water rating (1.15 allowance) and 85% AFUE on a COPPER tube-and-fin heat exchanger with atmospheric combustion — a non-condensing design despite the 'modulating gas boiler' nameplate.
The CHB models provide dedicated domestic hot water connections for adding an indirect water heater plus a wired sensor for indirect-tank control and temperature reporting. The boiler is wall hung (optional floor stand), ASME 'H' stamped to 43.5 psig with a 30 psig relief valve, vents Category I or Category III, and runs on 120 V / 60 Hz with a factory-wired cord and internal circulator; the gas valve modulates from 100% to 33% of input.
Utica prints a 10-year limited heat exchanger warranty and a 2-year limited parts warranty. Boilers.ca records the CuB line as a legacy listing: the page and current documents are live but the line is absent from Utica's category cards. No official Canadian-sales statement was found, so canadianStatus stays 'unknown'; gas, venting and combustion work belongs with a licensed contractor against the CHB 100-150 IOM Rev. G.
Best suited to
- Homes whose heat-loss calculation fits inside 130 MBH of input
- Heating-only systems pairing the boiler with an indirect water heater
- High-temperature retrofits that suit a copper, non-condensing heat exchanger

Frequently asked questions
What are the CuB CHB-130 ratings?
43.5–130 MBH input, 110 MBH heating capacity, a 96 MBH net AHRI water rating and 85% AFUE per the official sea-level ratings table.
Does the CHB-130 make domestic hot water?
Not directly — the CHB models are heating-only with dedicated connections and a wired sensor for an indirect water heater.
Is the CuB CHB-130 a condensing boiler?
No — the official 85% AFUE rating with a copper tube-and-fin heat exchanger and atmospheric combustion describes a non-condensing design, despite the product nameplate reading 'modulating gas boiler'.
