Wow lets see....Radiant. Radiant heat kind of spreads the heat out and heats everything as opposed to a blast forward that heats just in front and then the heat spreads around. Perhaps a poor explanation but I don't know how else to do it
Mine is Diesel/fuel oil/Kerosene. I have moved to Kerosene because it is cleaner but I don't use this heater anymore. I went back to a Torpedo heater. My goal is to build a nice garage with insulation and go with a mobile home furnace. I have one I use in my semi garage and I like it. If I could get the money together I would go mini split.
