It's more like they need the heat when it's cold out to help the engine start. Unlike a gas engine that uses a combustible fuel/air mixture that ignited with a spark plug, a diesel uses just the heat developed when the piston compresses the air in the cylinder (fuel is injected directly into the cylinder once the air is compressed).Diesels love heat.
Hemi owners have a more likely of wiping out a cam/lifter than the grid heater bolt on a Cummins failing.
