Editing Block heater (section)

== Considerations ==
The vehicle operator must have access to electrical power. In cold climates, parking areas for residents, employees, or students, or paid public parking areas, may have electrical outlets.

The operator must disconnect the power cord before driving away. Forgetting to disconnect can result in damage to the power cord or the vehicle. After a snow storm, the cable may not be visible under the snow. Residential overnight street parking may not allow an extension cord to cross a public sidewalk.

The energy used to heat the engine adds a cost. However, the savings in fuel generally outweigh this cost, especially if a timer is used to limit the heating period to about 4 hours before the expected start time. Taking the needed precautions, a [[kerosene]] jet-heater can also be used to pre-heat the engine.<ref name="MU Extension 2021">{{cite web |date=2021-01-12 |title=Unvented Portable Kerosene Heaters - Safety Considerations |url=https://extension.missouri.edu/publications/g1999 |access-date=2022-10-17 |website=MU Extension}}</ref>
