Heat diverting question

[Durantefarm]

I just had a 30x40 pole barn built . It’s all open to the roof . Here is a pic of my burner .my Question is how can I divert the radiant heat coming off the top from just going up but pushing it out ? I was thinking of making a heat diverter about out of sheet metal so heat hits and goes outward . Or is a better option just putting up a ceiling fan to push heat down ? Thanks in advance .

This thing holds 3ft logs but I’m losing all heat up to roof .

You need fans to move the high heat down and insulation to keep it in the building.
