Block Heater

From EcoModder

Introduction
Block heaters pre-warm the engine before starting. The reduced warm-up time can dramatically improve fuel economy, especially for short trips. It is recommended to put the heater on a timer that starts to heat the engine no more than about 3 hours before departure to avoid wasting electricity.
