REFLECTOR: Engine pre-heat

[Jeff Howell]

I would rather see 120v connected to a oil pre-hearter that was designed to heat the oil than a wal mart heater. I currently work at NASA and explosion proof is a must.  120vac is not dangerous when used properly. A heating coil, electric fan and a blanket is way more dangerous than approved oil pan heaters with no moving parts. Jeff

The 100LL and the motor oil aren't fire proof or explosion proof. It makes me nervous putting 120 VAC in the engine compartment overnight unattended. Maybe I worry too much.

one of the advantages of buying an actual oil pre-heater heater is that it is EXPLOSION PROOF. the walmart heaters with a little bit of 100LL can be dangerious, Although they heat the whole engine more evenly than the oil pre-heaters. Oil pre-heaters come in a pad form that rtv to the side or bottom of your oil pan. I would rather pay a few hundred more for the explosion proof heaters just for my own added insurance. I would hate to go to the hanger and see my plane burnt to a crisp... Jeff
