Has anyone used a 250 gallon oil drum for a rocket in order to make the heat riser bigger...

Not that I know of.. You can (already) put a MUCH larger heat riser inside a 55 gallon drum. I'm not sure I would recommend anything much larger that the 8 inch size for home heating. Though I have been thinking about 10-12 inch systems for hot tubs.. Those systems won't need barrels. What do you have in mind??
