Answers:    A Kilowatt hr = 1000 watts for 1 hr.
I estimate at "low" it still consumes 1000 watts/hr so that will be 24 hrs x 1 = 24 KWH per afternoon.

@ .15/KWH that would be $3.60/day or $108 for 30 days.

At full use would be $199.80/ month
Why did my clothes dryer stop producing boil?
It might. I'm using one as well but since I'm not paying the electric bill, I don't enjoy to worry.
