Don't know yet. There is already an electric heater but it runs forever trying to heat up the room so I don't expect much of a change if any. If it was set for 5000 watts in a large space it would be more for sure. Hardly ever gets to freezing here except this week when it snowed-very rare. Anyway I was impressed with the heater and wanted to pass it on. Many of the electric ceiling heaters are noisy and bussy-this one is smooth and quiet.
