Our take on the L.B. White Tradesman K125 Portable Kerosene Heater

The L.B. White Tradesman K125 is a portable kerosene forced-air heater rated at 125,000 BTU, aimed at construction sites, workshops and large garages. It burns kerosene and uses a thermostat to cycle the burner, so it holds a set temperature instead of running flat out. Compared with smaller torpedo heaters it moves far more heat and covers a bigger open space, but it needs ventilation, a steady fuel supply and more room around it. It suits people heating a job site or outbuilding, not a bedroom or small office.

Questions and answers

Is the Tradesman K125 safe to use indoors?
Only in a ventilated space. It burns kerosene and produces exhaust, so it is meant for open or well-ventilated areas such as sites and garages, never sealed living rooms or bedrooms.
How much space does 125,000 BTU heat?
In practice it suits large open areas like a construction shell, warehouse or big workshop. Insulation, ceiling height and outdoor temperature change the coverage a lot, so treat any square-foot figure as a rough guide.
What fuel does it take?
Kerosene, typically clear 1-K grade. Clean fuel keeps the burner and wick working properly; dirty or mixed fuel causes smoke and starting problems.
Does the thermostat really control the temperature?
Yes. The thermostat turns the burner on and off to hold your setting rather than running continuously, which uses less fuel once the space is warm.
How does it compare with a smaller torpedo heater?
It delivers much more heat than the common 50,000 to 70,000 BTU units, so it warms a bigger space faster but burns more fuel and needs more clearance. For a small garage, a smaller unit is usually the better fit.
What maintenance does it need?
Keep the fuel tank clean, check the filter and nozzle, and store it dry between seasons. Kerosene left sitting can gum up the burner, so drain it if the heater will be idle for months.
