Utica Heating 15B Series

15B Series

The Utica Heating 15B Series Boiler is an affordable gas-fired water home heating solution.


  • Quality Heat Exchanger Design
    The 15B Series features a dependable cast iron heat exchanger with cast iron push nipples. The sections and push nipples expand at the same rate when heated. By using similar materials instead of less expensive gaskets, or steel push nipples, the boiler maintains a water tight seal.
  • Efficiency
    The 15B Series provides an annual fuel utilization efficiency of 82% as certified by the US Department of Energy.
  • Easy Installation and Maintenance
    The 15B Series features a Low Profile Draft Hood and Vent Damper. The low profile, compact design makes it ideal for low clearance installations.
  • Warranty
    20 Year Limited Heat Exchanger Warranty
  • Choice of Two Operating Controls
    Honeywell or HydroLevel 3250
    • Standard Honeywell control, with digital display and diagnostics, monitors water temperature and delays burner from starting until the residual heat energy with in the boiler is consumed.
    • Optional HydroLevel 3250, with digital display and diagnostics, adjusts the water temperature based on your heating system demand which further reduces your heating costs. It also features a built-in low water cut-off (LWCO) to protect the boiler from potentially dangerous low water conditions.
