Burnham 104139-01 Tankless Coil Replacement Assembly 222AR with Gasket

The Burnham 104139-01 is an OEM replacement tankless coil assembly designed for Burnham Advantage series boilers. Supplied as the 222AR assembly and includes a mounting gasket, this drop-in replacement restores on-demand domestic hot water production to your heating boiler system without requiring a separate water heater.

Tankless coils are finned copper heat exchangers that mount directly inside the boiler jacket. As cold supply water passes through the coil, it absorbs heat from the surrounding boiler water and exits at usable domestic hot water temperatures — delivering hot water on demand with no standby tank losses.

Key Features:

• OEM Burnham replacement part — engineered to exact factory specifications for the Advantage boiler line
• 222AR tankless coil assembly for correct fit and performance
• Includes mounting gasket for a complete, leak-free installation
• Finned copper construction for efficient heat transfer
• Restores domestic hot water capability to compatible Burnham Advantage boilers
• Direct replacement to simplify serviceability and reduce downtime

This assembly is the factory-correct replacement coil for Burnham Advantage boilers equipped with a tankless domestic hot water coil port. Always verify boiler model compatibility prior to installation. OEM part number: 104139-01.
