No and yes.
In your room, no oxygen will be consumed by the electric heater, so it's safe to use it in an unventilated room. Remember, though, not to cover it to prevent overheating (and possibly fire).
To create the electricity, though, it's very likely that some oxygen was used
(unless you get your electricity from a renewable source: hydro, wind, etc, or nuclear).
In the power station fuel is burned, so this does reduce the oxygen level, but not locally.

Why are room heaters kept at the ground level?
To circulate the air. The heaters warm the air closest to them, which rises. This forces cold air to replace the warm air - which is then heated... and the cycle continues.
How many electrons does oxygen have in its first level?
Oxygen has 2 electrons in its first energy level.
What are 3 examples of household appliances that use thermostats?
Refrigerators: Thermostats control the temperature inside the fridge to keep food cold and prevent spoilage. Water heaters: Thermostats regulate the water temperature to ensure it is at a comfortable level for use. Air conditioners: Thermostats monitor room temperature and adjust the cooling or heating settings to maintain a desired comfort level.
What is the concentration level of exygen necessary to support combustion?
Combustion generally requires at least 16% oxygen in the air for sustained burning. This is known as the oxygen concentration level necessary to support combustion. If the oxygen level falls below this threshold, combustion may not occur or may be incomplete.
Why is the process of photosynthesis called an air purifying process?
Photosynthesis is called an air purifying process because plants take in carbon dioxide from the air during photosynthesis and release oxygen as a byproduct. This helps to reduce the amount of carbon dioxide in the atmosphere and increase the level of oxygen, which benefits both plants and animals by improving air quality.
