    My apartment is all electric.
    My heating system is ineffective.
    So I use electric space heaters.
    I also use my oven, set on 'lo', and leave the door open.
    The space heaters use either 900 or 1500 'whatchamacallits'.
    The oven cycles on and off on low.
    Which of these uses the most electricity?

    p.s. this is not a riddle
    I really don't know. :shrug:

    Each coil that uses electricity to make heat is really about the same per watt, in terms of efficiency making heat. They simply are not efficient.

    An electric blanket on your bed [so once in bed your apartment's temps can go down], and a separate heater in each room [so you only heat the room your in]; is about as cheaply that you can heat with electricity.

    Actually, electric heating devices are close to 100% efficient. In other words, for every watt of electricity used an electric heating device will provide 3.4 BTUs per hour....doesn't make any difference what kinda of electirc device you use. Of course, if the heating device has a fan some of the energy consumed will be used to run the fan an dnot supply heat.

    Some will circulate that heat produced better and I'd be surprised to hear the oven was doing that job well at all. I'd expect the area in front of the oven is too warm and the further areas of the room are cool. If you place heaters by the outside walls you set up an air flow up the outside wall across the ceiling and down an inside wall.

    If you're renting, I believe the landlord is required to keep the heating system working effectively.

    Heating with your cook stove is even less efficient if you have installed a vent hood with outside exhaust. Even without running the fan, that hood dumps a LOT of heat outside.

    Yes, every watt of power that goes into a heater coil will make a watt of heat.

    It is considered that electricity is better suited to control systems and moving things [like air], rather than on making heat.

    Electricity is normally considered the most expensive source of heat.
