I've pointed out before that the official published fuel efficiency estimate for the Volt in Europe is 196 mpg (US gallons) which is not far from...
To be fair, it is also a result of their overall choice of battery size. An electric heater like the one in the Volt or LEAF would draw 5-6 kW of...
Whole house residential electric furnaces are commonly 10-15kW and cycle on and off like forced air gas furnaces. If you ran the Volt heater...
