Percentage wise the difference is minimal.

Granted it's engine preheater propaganda,
I believe there's some truth to the research in

or

I'm leaning towards a Reiff System, probably the Turbo XP system. It just
seems a better design especially with a
JPI EDM-700 installation.


I've had a TANIS system for about fifteen years, along with an Insight
GEM.
The "cylinder" heating is taken care of by heated intake bolts, so no
interference with anything else. The oil heating is via a heated oil
screen (the upper one).

Isn't the GEM a single cylinder monitor? The EDM-700 has six and I think
that precludes using the Tanis.


I have no experience with the Reiff system.

With a cover, my cylinders are usually around 100°F and the oil around
80°F
with OAT's down to -5°F or so.

Gets the cabin heater going more quickly, too, I surmise.
