You might think it wastes double the power.
It actually saves power. Instead of leaving the standard single 600 watt heater plugged in all night I have found that you really only need about two hours with double block heaters to reach close to the same level of heat you get running a single block heater all night.

I would consider leaving 600 watt block heater pugged in all night only when it's really cold outside (-20 °F or colder). Usually 1-2 hours is enough for a normal I4-engine. A huge V8 might need more time.
I would rather have 600 watt block heater working together with a 200-300 watt oil heater. Oil heater heats the oil much faster than any block heater.
