MASTER Oil Heater B360 Direct Fired 111kW

Direct-fired and uncompromisingly powerful, the MASTER B360 delivers 111 kW of clean, immediate heat without a flue — a workhorse for warehouses, construction sites, and agricultural buildings where ventilation is already sufficient. Unlike indirect units that sacrifice efficiency through heat exchangers, this heater pushes nearly all combustion energy straight into the space, cutting warm-up times and fuel waste.

Highlights

• 111 kW (379,000 BTU/h) heating output for large volumes up to ~2,500 m³
• Direct combustion with electronic ignition and gear pump for reliable starts
• 105 L fuel tank supports long unattended operation
• High-efficiency axial fan moves 3,300 m³/h for rapid air circulation
• Robust steel housing with IP41 protection and integrated wheels
• Optional external thermostat for automatic temperature control

In daily use

The B360 is built for continuous duty in demanding environments. Fill the large tank with diesel or kerosene, set the optional thermostat, and the heater maintains the target temperature without constant supervision. The electronic ignition eliminates manual lighting, while the gear pump ensures steady fuel delivery even in cold conditions. Because exhaust gases are released into the heated space, the area must have adequate ventilation — a standard requirement for direct-fired units. The included wheels and balanced chassis make repositioning straightforward across smooth floors.
