I've been following this thread for a while and I'm surprised that
nobody mentioned an other type of oil heater. I had installed it in my
Grumann Tiger. It' been ten years since I've bought this heater so
perhaps it's not in the market any more.

The heater looks like an electronic circuit board. I think it was
rated at 200W, but don't nail me on that. You had to clean the bottom
of the oil pan and then the heater was glued to it. You secure the
110V plug so that it can't rip out the heater when pulled. You plug it
in and leave it connected all the time. The heat from the oil pan
travels up and keeps the engine warm enough not to have to be worried
about cold start. I guess if you live in Alaska you may want to wrap
your engine cowl with a blanket. In 1992 I paid about US$130 for it.
It was all over Trade a Plane. Never had a problem with it up here in
Toronto.

If electricity comes from electrons...
does that mean that morality comes from morons?

One idea I heard was to use flex ducting to direct car exhaust into
the cowling; that does present CO concerns, but on could leave the a/c
doors open. - Mike
