Tradesman K125 Portable Forced-Air Kerosene Heater – 125,000 BTU High-Output Jobsite Heater with Integrated Thermostat and Multi-Fuel Capability

Overview

The Tradesman K125 is an industrial-grade, high-capacity forced-air heater engineered for construction crews, warehouse managers, and agricultural professionals who require immediate, reliable warmth in large, unheated spaces. Delivering a massive 125,000 BTUs of heat, this unit is capable of warming areas up to 3,125 square feet, making it an essential tool for curing concrete, drying drywall, or maintaining workable temperatures in open-air garages. The defining feature of the K125 is its heavy-duty multi-fuel system, which is designed to run efficiently on K1 kerosene, #1 and #2 diesel, or JP8 fuel, providing maximum flexibility based on jobsite availability.

Durability and safety are at the core of the Tradesman design. The heater is anchored by a rugged steel housing and a high-limit thermal switch that automatically shuts down the unit if internal temperatures exceed safe operating limits. Unlike basic torpedo heaters, the K125 features a built-in adjustable thermostat, allowing the operator to set a specific temperature and conserve fuel once the space is warmed. Built on a heavy-duty frame with large, puncture-proof wheels and an integrated fuel gauge, this portable heater is a high-efficiency powerhouse built to provide a lifetime of service in the harshest winter environments.

Top Performance Features

• 125,000 BTU Heating Capacity: Provides a high-velocity stream of heated air to rapidly raise the temperature in large commercial bays or outdoor workspaces.
