    Tanis heater. I leave mine plugged in all the time. Oil temp at 80-85 on start. Prevents condensation from forming. Easy to install.
    Oil pan heater and four intake bolt heaters.

    No doubt the Tanis system is a good one and despite controvery regarding such systems, I mostly agree with their statement on their website that leaving it on all the time is OK....

    "Resistance heat cannot create moisture. Moisture is always present inside your engine and specifically within your oil. Use of our system will NOT result in corrosion because a Tanis preheat system keeps all of the metal parts that are above the oil level above “dew point” and as a result condensation cannot occur on these parts. Tanis preheat systems are not to be cycled on and off as this could cause the engine to go through “dew point” (timers and thermostats are not to be used)."

    Keeping the cylinders at a temp at or above the oil temp is part of the benefits of their design. But, I would comment that rust can form when temps are above dew point, so keeping it above dew point does not necessarily eliminate rusting.

    For many reasons, I prefer not to use a system that must be left "on" continuously. Things can go wrong (I worry too much about systems that I can't monitor.) and cold steel is less prone to rust than warm steel.

    My preference would be to dehumidify the crankcase after flight and leave it cold until just before wanting to fly. Cold and dry air, with Camguard and/or oil that sticks to all surfaces is the best rust protection IMHO.

    Since I am a recreational flyer, the two hours to pre-heat is OK for me, but if time were more valuable the Tanis system (or the Aerotherm fan) with a cell phone activation or the ultra fast pre-heat like Dan L uses would be good. Getting the plane ready is part of the fun for me.
