Direct oil-fired fan heaters from 48 to 111 kW: the flame heats the air stream directly, which gives high output from a light, mobile unit. The combustion gases are part of the warm air, so these heaters are for well-ventilated halls, open building shells and outdoor work only. Fuel: diesel or kerosene, depending on the model also heating oil EL or HVO 100. Our heater guide covers sizing and ventilation.
