Does anyone have a suggestion for keeping the engine bay warm overnight?

Many of my flights are at dawn and the cooler temperatures now mean my 912S is taking ages to warm up. Rather than waiting for 10 minutes (+) starting from ambient temperature, I’m convinced that a 20 degree head-start with some kind of overnight heater will easily halve the time.

I could just put it in the engine bay and turn it on the night before I fly.

Does anyone use one of these?

To help warming up on a Rotax 912 for winter months:-

Is an oil thermostat fitted?
Have you got the coolant radiator partially blanked?
Also Oil cooler partially blanked?
Both will speed up engine warm up.
Takes a bit of experimentation to get right amount blanked off but then should warm up as fast as in summer.

Oi!

I’m quite up to date actually, I’ll have you know. I’ve got power steering on my Land Rover and everything. :D

No oil thermostat (I dont think).

Maybe something this simple wood help?

You definitely need a proper Oil thermostat for a Rotax fitted in the line between the oil pump and tank. Makes a big difference.
Talk to either CFS ( Rotax dealer) or Eccleston ( sub dealer). My choice would be Eccleston as thay are more user friendly.

I made this to keep my O360 dry in the winter. Fan and about 40W of resistors blows warm air into air intake and flexi tube recirculates from other air intake.

You mean you don't have your butler start it up and have it ready for you? :D

£20 would get you an electric blanket, designed for humans. Wrap it round, shove it on a time clock... (no mains electricity in my hanger so i can only dream...)

Your own first idea was the best. Scrub round anything “home made” as you may have a tough time explaining to the insurance company about the pile of ashes that was your aircraft and hangar.
