Dunno, that’s only a by-product of why I’m doing it. But there must be benefits to engines to start up at 25 degrees compared to 0 degrees.

Every component in an engine is manufactured to a dimensional tolerance at (21.5deg C if I remember right). So there will be variations in dimensional shrinkage depending on the bulk of each component.
Effectively, nothing fits properly until working temp is reached.

I just want to be able to get airborne without a 15 minute wait!

As for which bit heats up faster than the other, I’m not really that worried about that bit.

Just sayin that’s how it gets wore out

Lucky you - for most of us that would be less than normal

The cockpit to get rid of the condensation .

Not fun with ice on the inside .

I have to say it's unaccpeable in 2020 that the modern aviation engine lacks temp control.

Slight thread drift (and may be too modern and high-tech for Mr Farmer) but I’m using remote switching via the internet and Moes devices for a few things around the hangar and workshop. You do of course need a working WiFi set up but it makes switching things on and off from home a piece of cake. On a really cold morning I can switch the workshop heater on before I leave home and enjoy an extra productive hour when I arrive.
