I'll use solid state (thyristor, yes, for DC) switch, that's given.

We don't have very cold weather in Portland, practically never snows.

I'm trying to decide id a few watts of loss worth ripping apart the
dash.

BTW, other than U-shaped water heating element and overloaded
large ceramic resistor immersed in water, can anyone suggest a
good water heating element? Will just two metal plates immersed
in salty water do the trick?
