I smoke cigars outside on the covered rear porch year round. For the past couple years I've been using a tank top propane heater with mixed results. One of the draw backs is I tend to run out of fuel half way through a cigar. A couple weeks ago I ran across a Presto Heat Dish heater at Costcos and decided to give it a try. This is one of those heaters with a reflector disk that looks like a small satellite dish. To my surprise, this puts off far more heat then my tank top. I set my heaters on top of a bucket so that the heat is more concentrated toward my upper body and face. I had to push this heater about a foot further away from me, then where I had the old propane tank top. I've been out there when temps where in the upper teens, and so far, so good. Needless to say, the old tank top has been retired, plus I no longer have to worry about running out of propane.
