Has anybody explored (or built) an engine pre-heater using a portable oil filled electric heater? You know, the ones that look like old fashioned radiators?
Seems to me this might be a reasonably safe approach given the fairly low surface temperatures of the fins, no exposed glowing heating elements, etc. The thought experiment approach would be to fabricate a sheet metal enclosure on one side of the radiator with a pair of 4 inch round outlets on the top of the enclosure to attach scat tube or similar. Tubes would then feed cowl inlet openings via convection.
Any ideas, comments, experience?
