This is a new-in-box heavy duty commercial grade patio heater made of 304 stainless steel very similar to this one at Costco. http://www.costco.com/Browse/Product.aspx?Prodid=11165131&whse=BC&topnav=&browse=&lang=en-US&s=1 I bought two of these and since I can't fit it on the patio of the house I just bought I am selling the one in the unopened box. I don't check my Email often so would be best to call me at 264-2190 if you would like to see/purchase this heater. newmexico
