Capacity: 105 – 496 MBH Input
Efficiency: to 86%

North America’s Best Built Full-Featured Oil Boiler

Performance, durability and versatility rank Slant/Fin’s Intrepid among the world’s best oil boilers. Intrepid is a full-featured oil boiler with models in hot water and steam with options for tankless heaters and direct vent models. All feature simplified maintenance. Energy Star models with 86% AFUE. An exceptionally low draft loss ensures excellent performance across a broad range of chimney and draft conditions. More Btu’s per section than ordinary boilers.

  • Input: 105,000 to 469,000 Btu/hr
  • 0.75 to 3.35 GPH oil input
  • For residential to light commercial requirements
  • Dual firing rates
  • High efficiency. AFUE to 86.0%
  • Domestic hot water coil optional
  • Robust cast-iron heat exchanger
  • Installer-friendly features
  • Steam models available

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. Intrepid water boilers are so reliable, they are backed by a lifetime 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

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.

Q3 Boiler

The Q3 boiler is a high-efficiency hot water oil-fired cast iron boiler. Its cast-iron design is recognized by heating professionals everywhere as the longest lasting, most durable heat exchanger material. It’s an ideal choice for new construction.

The Q3 is DOE 2021 compliant.

The Q3 Series efficiency is a result of the boiler’s unique three pass design heat exchanger with specially designed baffles for maximum heat exchanger contact, flue circulation, and heat transfer. AFUE is 87%.

The three pass design of the Q3 makes it very quiet too. There is plenty of room for thermal expansion of the flue gasses to keep burner and flame noise to a minimum. It is easy to clean, the door is reversible, the baffles are removable and brushing the flueways is a snap.

The Q3 boiler, like other Slant/Fin oil boilers, will operate cleanly under all different operating conditions. We’ve done the testing and have matched burners and components to this boiler to make sure the boiler will stay running clean after you leave the job.
