This is a video I took that proves my proof of concept.
I am planning on using this torpedo heater as part of a dual use system. 1 system that allows me to burn Kerosene/Diesel/#1 Fuel Oil as it was designed to heat my garage as the unit was designed. The 2nd system would allow me to push the heater tight against a 55 gallon drum that will be fitted with baffling to keep as much heat in as possible. I will then add some heavy gauge 4" pipe that I have. These pieces will run in one side and out the other to allow air to flow through them via a fan. This should help get more heat out of the system. I have also looked into using a couple radiators or pipes filled with water/antifreeze then the coolant can be pumped through them and to a radiator with fan in my garage. This will extract the hot air and blow it around my garage nicely!

Heater info:
This is an older model "Work Horse" 65,000 BTU "torpedo heater". It was designed to run on Kerosene (K1) or on #1 Fuel oil. I have also run it on diesel fuel with NO issues whatsoever.
