So Pablo's plugged in tonight with a new engine block heater. The dealer has to remove a sub-frame member to install it because the manufacturer doesn't want to add $5 to the manufacturing cost. So it's 3.5 hours labour making for about a $400 total all in. Youch, but I knew that going in. $1 per watt ironically, as confirmed by the WattsUp meter.
Anyway, I'm hoping to save 13 cents worth of gas each weekday morning by spending 8 cents worth of electricity to do so. My mother used to mention pennywise - pound foolish or something like that, well this certainly is. I reckon the payback is about 40 years assuming 75% seasonal usage.
Anyway, tonight there's no timer involved so it's 32 cents and 11,000 BTUs of warmth for the engine. Watch me get the typical 18 LHK on my first leg tomorrow and see no difference.
