i purchased this heater december 2nd,my billed in january was only $65 and that included 2weeks without it. the sales associate got on line before my purchase to show me the difference between this model and another being offered for $100 cheaper. the heater does not dry out my sinuses or skin and is heating my entire house. i am all on one floor and the only time my furnace kicks on is when the outside temperature drops under 20 degrees. i was so impressed by its performance i bought my daughter one for christmas.
