Your basic fan motor uses about 4 amps x 120 volts = 480 watts. 500 w =1/2 kw. multiply your cost for elec in cents/kwh to get the cost. Ie 8c/kwh x .5 kwh = 4c/hour x 24 hrs = $1/day + taxes = $365/yr. Shocking Eh. Thats why we sell new units with energy saving ECM motors. Not sure what a ceiling fan uses but if you can find the specs/amperage draw you can figure it out. You can get Norton electric furnaces (my favorite) with ECM motors. The elements may be obsolete for your old unit and they can be a SERIOUS fire hazard when they start shorting out. Wiring gets VERY brittle and starts arcing and sparking on those old units due to poor/corroded/overheated connections etc. Good chance some of your elements/sequencers are already faulty/burnt out and contributing to your high cost. Need an experienced service electrician or tech who does electric furnaces ( few do) to check it.
