Yea, I have one rusting in storage. The radiant style is better. Smaller. Fuel tank comes out for refueling. 18 hours per fill. Fuel level, the wick is in, doesn't change as the fuel is consumed making periodic adjustment unnecessary. Of course lighting, extinguishing and refueling would be done outside on the small balcony. I don't own the model shown but my 30 year old heater is similar.

PS I just looked at the ad. Don't use diesel!!! Around here they sell K1 (kerosene) out of the pump for $4.00 a gal. As for refueling, a cheap syphon pump is included. When fuel shows in the sight window on the tank you open the vent on the pump stopping the syphon. I've never spilt a drop.
