M optimized 140,000 BTU Diesel/Kerosene Forced-Air Heater — 10 gal / 38 L Tank, Thermostat (40°F / 5°C to 110°F / 45°C), Portable with Wheels for Garage & Construction

Powerful, rapid heating: Delivers 140,000 BTUs of forced-air heat to warm large spaces — ideal for workshops, barns, farms, garages and indoor areas up to 35315 cu ft / 1260 m3. Keeps equipment operating efficiently and improves worker comfort. Dual-fuel capability: Compatible with both Kerosene and Diesel (use only one fuel type at a time). For best results we recommend 1-K kerosene.

The unit includes a fuel gauge and an automatic low-fuel shutoff to prevent run-dry situations. Precision temperature control and safety: Features a thermostat knob with room temperature display adjustable from 40°F / 5°C to 110°F / 45°C; the heater stops heating once the room exceeds the set temperature to conserve fuel. Built-in overheat protection shuts the unit off at 176°F / 80°C.

Large tank, long runtime: The 10 gal / 38 L fuel tank typically consumes 1 gal/h under normal conditions, allowing up to 10 hours of operation on a full tank to minimize refueling interruptions. Portable and job-ready: Lightweight design with a convenient handle and wheels makes it easy to move where you need heat quickly — suitable for construction sites, warehouses, open barns, docks, shops and similar work environments.
