Jefferson Tools JEFHTSPC105 Inferno 105 Direct Oil Space Heater

When the temperature drops but the work still has to move, you need heat that shows up fast and keeps pace. The Jefferson Inferno 105 Direct Oil Space Heater is built for large, well-ventilated environments where rapid warm-up and strong airflow matter—workshops, warehouses, garages, agricultural buildings, and busy industrial spaces where stopping isn’t an option.

Delivering a powerful 105,000 BTU / 31kW heat output, the Inferno 105 uses a direct oil-fired system to generate a high-temperature heat stream inside the combustion chamber. A high-displacement fan then drives warm air out quickly and consistently, helping you bring comfort back to big areas in a short time—especially useful in draughty buildings where slower heating methods struggle to keep up.

Designed for real-world site and workshop conditions, it features durable steel construction with solid rubber wheels for easy movement across rough floors. Day-to-day usability is strengthened by practical touches like an integral fuel gauge, plus safety-focused systems including electronic flame control, thermal protection for the motor, and an error indicator light to support dependable operation during long shifts.

With a generous 38L fuel tank and an economical maximum fuel consumption of 3.0L/hr, the heater offers up to 13 hours endurance (usage dependent), reducing refuelling interruptions when you need steady, uninterrupted heat.
