Utica cub-chb130 Wall Hung Gas Copper Boiler 130 Mbtu

Product Description

The UTICA cub-chb130 is a wall-hung, heat-only hydronic water boiler designed for residential and light-commercial hot water heating systems. Part of the CuB Series, this natural gas boiler features a copper heat exchanger and delivers 130 MBtu input capacity at 85% AFUE. An advanced modulating control system adjusts fuel delivery based on actual load conditions, reducing fuel consumption during mild weather without sacrificing comfort. Licensed plumbers and HVAC technicians install this unit as a primary heat source in hydronic systems. The modulating operation makes it well suited for installations where efficiency and reduced runtime are priorities.

The cub-chb130 is intended for wall-hung installations in residential hot water heating applications. Its modulating control measures outdoor and load conditions to match fuel use to demand, which is especially beneficial during shoulder seasons when full boiler output is not required. The copper heat exchanger provides reliable heat transfer in a compact, wall-mounted form factor. This boiler is sized for systems requiring 130 MBtu input and is configured for natural gas supply.

Key Features

• 130 MBtu input capacity for whole-home hydronic heating demand
• 85% AFUE rating for above-minimum efficiency performance
• Modulating control system matches fuel input to actual load conditions
• Copper heat exchanger construction for durable heat transfer
• Wall-hung design conserves floor space in mechanical rooms or utility areas
• Natural gas configuration with heat-only hydronic output

Compatibility

Designed as an OEM-style replacement or new-installation boiler for wall-hung natural gas hydronic heating systems requiring 130 MBtu input capacity. Alternate manufacturer part number: CHB0130000110.

Installation Notes

Installation must be performed by a licensed plumber or HVAC technician in accordance with local mechanical codes, IFGC requirements, and the manufacturer installation instructions. Shut off the gas supply and disconnect electrical power before servicing or replacing any boiler components. Verify proper venting configuration, gas line sizing, and hydronic system pressure before startup. Do not operate the boiler without confirming all connections are leak-free and the system has been properly filled and purged of air.
