Did you see any benefit of 220 over 110?
Did you see any benefits or savings gong big like that over the standard size?
My experience with the oem 400 watt honda block heater is 2 hours gets the coolant up to about 110 degrees or so. Any less and its under 100 degrees, after 8 hours you get to about 130 degrees, so 2 hours became my and a few other users standard.
No noticeable improvements in mpg, but its nice to have heat withing 2 miles of driving.
