Advanced design ensures superb performance

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.

Quality assured

The Intrepid boiler’s cast-iron design is recognized by heating professionals everywhere as the longest lasting, most durable heat exchanger material. The cast-iron heat exchanger is assembled with durable metal push nipples.

Specially shaped thermal pins promote efficient heat transfer. For reliability, every burner is fully combustion tested and fine-tuned in the factory for optimal performance. Final adjustments are made by the installer, based on the unique chimney draft conditions of each individual house. A generous 3″ supply tapping helps produce drier steam, resulting in quieter operation of the heating system. Intrepid steam boilers are backed by a one-year limited warranty

Easy to install and maintain for like-new performance

The Intrepid boiler is “service friendly.” Virtually 100% of heat exchanger surfaces are flue brush accessible to maintain the high heat transfer characteristics of the boiler’s cast-iron thermal pins. The easy-off flue collector can be quickly and repeatedly removed and put back into place with fiberglass rope seal. The burner door swings open for routine servicing. It also lifts off, making it easy to move the boiler to its installation location.

Optional high output tankless heater coil

This “instant” hot water maker serves the needs of your kitchen, bath, and laundry. Intrepid’s extended coil well accommodates a larger coil to maximize output. The cover plate is visible for easy inspection. Stainless steel cap nuts facilitate routine maintenance.
