    Why do Finnish parking spaces have electric posts?

    The lämmitystolppa and how it is used.

    Answered at: Checked at:

    Short answer

    The posts are heating posts (lämmitystolppa). They supply electricity to the car's engine preheater, usually a block heater that warms the coolant. A cable from the car is plugged into the post before cold mornings. Autoliitto says preheating helps older cars start at all in frost and saves money, the car and the environment. Many posts have a timer or a button so the power comes on only when needed.

    Why

    1. MTV Uutiset quotes Autoliitto on why preheating matters in frost.
    2. A block heater is plugged into a socket with a power cable.
    3. Moottori notes that electric heaters include block, hose and oil pan heaters.

    Details

    Some cars have an interior heater on the same cable. MTV Uutiset notes that interior heaters are meant for a few hours of use at a time because of the fire risk.

    Tip

    Do not use someone else's heating post without permission. Posts in housing and work car parks are often assigned to specific spaces.

    What may differ

    Not every car has an electric preheater. Some use a fuel-operated heater instead.

    Common misconception

    The posts are electric car chargers.

    What actually happens

    Most are heating posts for engine preheaters, not EV chargers.
