Not so. Yes, a fan does "use" some electricity, but, as stated by the First Law of Thermodynamics, energy can not be destroyed, it can only be converted from one form to another. A fan converts electrical energy to heat energy and mechanical energy (wind). The wind is then converted to heat, by way of air friction. No energy is lost.
Thus, any 1500 watt heater. either with or without a fan will put out precisely 5118.2124495 BTU/Hour. The electric heater is the only type of device that is 100% efficient.
