I'm looking for ideas on building a shop heater. The type made fron 2 55gal barrels stacked. Where the top barrel has pipes.with a blower to distribute the. Heat. I've look online but haven't found detailed instructions on the build and setup. If anyone has one would you explain.
1. Could I drip the oil. Or does it have to be sprayed

2. What size blower for the oil & what size blower for the top barrel.

I understand the fundamentals. Just would like some guidance from someone with experience on this build.
