Do electric space heaters use up oxygen?
Answer Hello, No electric space heaters that I know of use oxygen. Electrical energy is converted directly to heat energy. It’s the same as in an electric cook stove. The electrical power comes from a power plant that may be atomic powered, but more likely burns some fossil fuel. The fossil fuel power plants would consume oxygen. But I think you were asking about oxygen in your home. There may be some kerosene or fuel oil burning heaters that use electricity to power a fan. If so, that would consume some oxygen.
