We have just erected a premenantly fixed steel gazebo/sunshade type of thing on the patio decking. We are now looking for a good heater that will efficiently take the chill out of a late summer evening. The Gazebo is 10x12 and is adjacent to the house. There seem to be loads available but wondered if any of you expert chaps have any recommendations for one that will give a good overall effect rather than a focussed one towards one area as such. Thanks
