  1. It's getting cold out here and I need a heater for chopping logs. I
    like to make my 1000W Holmes mini heater run medium. Right now it's
    built to be stuck on HI and my feet gets burned. So I thought maybe I
    can hook several car alternator diodes facing the heater coils and
    make it run cooler. Here, take a look at my sketch and please let me
    know if this is possible.

    I don't know what a car diode is rated at in terms of piv but I would
    definately use a diode with a piv of 400+ volts and an If of 20 A. This
    would provide roughly 50% derating and should work just fine.

    by adding diodes I assume in series you adding waste as basically heaters. WALLMART sell them heaters for $20.0 the diodes will cost more. Get real
