Yes.
You can leave an electric heater on all day, but it’s not always the most energy-efficient option. Electric heaters can be expensive to operate, especially if you’re using them to heat a large space. It’s usually best to use an electric heater only when you need it, and to turn it off when you’re not in the room. If you need to heat a space for an extended period of time, it may be more cost-effective to use a different type of heater, such as a central heating system or a wood-burning stove.
