I need one of these in the worst way. Last night it was 22 degrees, 40 inside the house. It's now currently up to 49 degrees. I am working toward getting a heater unit for the window. One of these will heat my tiny house nicely throughout the winter season, and keep it cool in the summer. Could you remember us during this holiday season by dropping some coinage into my tip jar? The life you save could be my own.
