This one has a better design, but I think they are more for ambiance than a source of outdoor warmth.That is neat looking but maybe not so practical for a fire pit. Maybe after the propane tanks gets really hot, it will put off some heat. It seems that fire gazing would only be practical when looking straight on from the one end, but what would I know, I have never seen one in use nor ever heard of one prior to this post.
Now that one looks to do a good job of heat and ambiance but it looks a little overbuild. Is that 1" plate on the wings and 6" box tubing for the struts? WOW.
