OAT 13C car cold soaked over night, on first boot and up to ICE start the CANVIEW showed the ICE temp as 32C. my Classic with the block heater which works out to 324 watts on for 3 hours and the OAT was 12C on ICE start the ICE temp was 47C. We pay 6.5 cents a kilowatt so I get 47c for less than a dime. any guesses on what the ICE temp would be with both the thermos and a block heater on a G2
