Engine pre-heat guidelines

[MacCool]

In an area where winter temps are typically 30s - 40s (F°), the Twin Hornet 22 might work fine. I can't attest...I have more robust needs, and my cowl and intakes are not particularly amenable to that configuration. I can endorse the quality of construction by that company as I do use a Hornet 45 cockpit heater and like it a lot.

What is different about your cowl that would make this heater a poor choice for your plane? All RV's are the same?

Mid 20's to mid 40's (F) would be of concern here.

All RV's are similar. I have a carbon fiber-capped plenum which leaves no room to shove a pair of Hornet 22's in there. I have zero interest in de-cowling to apply pre-heat and find that a Reiff XP sump heater and cylinder bands perform that pre-heat function much more efficiently in my particular local climate. All I have to do is remember to plug it in to the cell-phone siwtch before I leave the hangar...just another step in addition to plugging in the dehydrator and the battery maintainer. My Turbo XP is entirely plug-and-play, and all I have to do is pull up the app and turn it on remotely about 4-5 hours in advance from wherever in the world I happen to be.
