Cold Starts

Even then, without proper insulation you can still get corrosion. I no
longer leave mine plugged in 24/7 (I have Reiff cylinder and oil pad
heaters), because before my recent overhaul my mechanic noted that the front
cams were badly spalled and had sigificant corrosion where the rear ones
looked nearly new. The most likely explanation was the uninsulated prop
acting as a heat sink on the front end of the engine providing for a heavier
condensation density near the front of the engine. Reiff's article does say
to use a cover, but they fail to mention also insulating the prop.

Leaving heat on the engine all the time may set you up for condensation
rusting - depends on the details...

Yes...unless you use both a cylinder AND an oil sump heater.

It is, apparently. It also must be "customized" to the particular engine.

Right now it looks like $2300-$3000 or so for the Tanis system, or $675 for
the Reiff system for the bird I'm looking at.

Wow. When I installed my TANIS, with the heated bolts, it was less
expensive than your Reiff quote.

What kind of bird?

What all came with your system?

I once got some numbers from the tanis website, but can't find them now. I
do recall that it was expensive.

The Reiff system is their top of the line with all the goodies. I like the
Reiff design better from what I see, so if someone can tell me why Tanis is
better, I'd appreciate it.

Well you've got six cylinders vs my four. My TANIS system included four
heated cylinder bolts, a heated oil screen, a plug for the AC, and all the
necessary cabling. My AC plug is wrapped to the oil filler tube -- a plug
mounted on a plate is available. The cost was under $600. But that was a
few years back.

Not being an engineer, I can't discuss which is better, or even if one is
better than the other.

Ya put two glue on oil sump heater pads on that 550, wrap the whole
thing in a Kennon cowl cover and your pre heat problems are solved. If
I have to park outside they both get plugged in, if I'm in my hangar
then just one. After a few hours the oil is at 100F and each and every
CHT and EGT is 80F. All for less than half of that Tanis and Reiff
crap. Plus have you seen what all those cords look like under the cowl
after a few years of use? You will be replacing, splicing, etc.
They're always in the way when it comes to maintenence thereby costing
you more money.

I agree, all you need is the heat pad. But you can't leave it plugged
in all the time, you have to plug it in a few hours before the flight.

After I put the plane away the nose mitten goes on and the cord gets
plugged in, assuming the temp won't be over 45 before I fly again.
