For those who want an alternative heat source but also enjoy entertaining outside during warmer months too for example hosting family gatherings or parties where open flame fires can be dangerous due to wind gusts blowing out flames and sparks towards guests seated nearby, opting for something like propane is usually best because they're easy enough to turn on and off with push button ignition plus require very little maintenance over time compared to wood or gas burning stoves, plus they also have a much shorter lifespan too. Another benefit of propane is that there are no ashes or fumes to clean up afterwards like with wood burning types either so it's more convenient overall for those who don't want as much work involved after hosting gatherings outside.
