Overall I am very happy with the natural gas heater. Relatively easy to build and fires up very easily. My only complaint is that if you want to use this as a portable heater and move it around there is no way for it to be secured to the patio unless you want to bolt it to the ground which I don’t want to do as I like to move it around. With the propane patio heaters the weight of the tank keeps it from tipping over however with the natural gas heater it is extremely tipsy and any little movement by wind or even slightly touch will cause the heater to fall over. I have searched the internet for a gizmo that will help keep it in place and as of now no luck
