I put a wood burner in my GH and it works just fine. Only problem is keeping it going over night. Plus wood heaters are a lot of work. I stopped using it and put in a thermostatic controlled propane radiant heater. Cost a little more to run but is better for me and more reliable. I will run the wood heater if I am going to be in the GH for any length of time plus the propane heater will take over when the fire goes out.
