I think a 5kw heater would heat that area without a problem. Especially if you recirculated the air. 8kw are really 5kw so don’t worry about that when shopping.
Just make sure you keep a battery source between generator and heater. That way if the generator runs out of fuel or dies, you don’t toast the heater.
