Cost of running an electric space heater?
Cost of running an electric space heater?
(OP)
How can I calculate the cost per hour of running a 1500 watt electric heater if the heater runs on 120 volt power,and pulls 12.5 amps.
Thanks for your help and any explanations you may provide.

RE: Cost of running an electric space heater?
this assumes that you normally consume enough power to overcome the base charge, etc....
if you have demand charges, etc. then the cost may or may not be higher... (demand charges are usually for commercial and industrial customers)
RE: Cost of running an electric space heater?
total kwh= (watts/1000)*hrs run
Total cost will be (cost/kwh)*kwh used.
In your case if use your heater for one hour, total kwh consumed will be 1.5kW*1 hr = 1.5 kwh.
For your info, Watts=V*I for single phase (which is your case). 1500W=120V * 12.5 Amps.
Hope this helps.
