• Quality Heat Exchanger Design
    The KWC 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 the boiler maintains a water tight seal.
  • Efficiency
    The KWC Series provides an annual fuel utilization efficiency of up to 86.2% as certified by the US Department of Energy.
  • Warranty
    20 Year Limited Heat Exchanger Warranty (Residential)
  • Operating Control
    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.
  • Swing Burner Door
    Provides easy access for servicing and maintaining the burner/boiler.
