You can leave a Duramax block heater plugged in for several hours, typically 3 to 4 hours, to adequately warm the engine for easier starting in cold weather. However, leaving it plugged in for extended periods, like overnight, is generally safe but may lead to unnecessary energy consumption. Using a timer can help optimize usage and reduce electricity costs.
