How It Works

The Intrepid boiler is designed to protect against the adverse effects of changing operating conditions. Many boilers suffer from poor combustion and soot buildup when their setup conditions are changed by cold oil, cold air or changes in chimney draft. The contoured shape of Intrepid’s heat exchanger has one of the lowest draft losses in the industry. This supports stable combustion. Burners are configured for each specific model to provide smooth, clean, efficient operation. Unlike most oil boilers, Intrepid’s push nipples are located to the side, out of the way of the flue gasses. This creates more uniform heat transfer, minimizes draft loss and reduces soot build-up.

For Steam Model: A generous 3” supply tapping helps produce drier steam, resulting in quieter operation of the heating system.
