Description
The Mr. Heater 125,000 BTU Forced Air Propane Heater is a powerful, portable heat source designed to warm large spaces quickly—ideal when you need dependable warmth on a job site, in a workshop, garage, or barn. Delivering 125,000 BTU per hour and capable of heating approximately 3,000 sq. ft., it uses forced air to move heat fast across open areas. Continuous ignition and a high temperature limit switch simplify operation and provide automatic control during extended use. QBT technology makes this unit about 50% quieter than a standard propane heater, so it’s less intrusive while still robust. On the low setting it can run up to 11 hours on a 40 lb. tank, and a 10 ft. hose with regulator is included for immediate connection to your propane source.
