fireplace heaters home depot

is it cheaper to use electricty to have my wall heater on or to plug in a portable heater?
It is so cold out and I am curious to know if it costs more to run my (not gas) wall heater or to purchase a portable heater. I really want to purchase one of the electric fireplaces that home depot sells, just wondering if it would help save my power bill.
Thank you
I am in Seattle
your wall heater should be more efficient than a plug in heater. The wall heater is most likely hooked to 240 volts which will use less energy to heat up a room than a plug in 120 volt heater. having insulated walls and attic and “newer” windows will keep the heat in. Check with your power company for windows or insulation, Most areas will pay for some of the work, depending on if your on low income or not. Good luck
