Engine Pre-heater

So now that winter is over thought I?d give you a little feedback on the Twin Hornet 22 Preheater. Worked great. Simple. Just shove it in your oil door and put a couple blankets over the cowl. I was seeing consistent 65 degree engine temps at start up in 30-40 degree outside air temps.

Sure. But it was a cheaper, didn't have to install it, and it heats the whole engine compartment. Not a contest here, just saying - it's simple.
 
Yea, but can you through it your other airplane, or into your cockpit onto you seat? So there. Your move. LOL
 
I have to agree with Tacco, I have made units similar with a built in Thermostat, the Beauty is that you heat the whole engine with no cold spots. When you heat the oil with a pan heater the Moisture in the oil Creates condensation on any of the cold parts which include the case the cam and parts of the crank. I believe this is a better way to heat your engine!
FYI you should cover your prop with some form Of insulation to keep the prop acting as a heat sink.

Looks nice and simple. Did you try it in cooler temps (like 10-20F?). Was your plane in a hangar?

Thanks for sharing.

Yes, hangared and occasionally that cold. Worked fine. I also use intake plugs and my prop is composite (not so much of a heat sink)
