Bought this heater unit to try on a generic stove that looks the same style as the Gosystem unit, you all know the type! It fits perfectly on the grill cover. Tried this in the garage with the door open and it gives out some good heat and on full power, you can see the inner layer glow! The heat is felt all around the unit and above. It
certainly gets hot! As it says, don't use this in a tent, and certainly do not remove the heater part and leave it on plastic or anything that is flammable,as it stays very hot for a while after removal. PS use the included removal tool. For a small space i would recommend this heater attachment. The only gripe? The bulk for packing. Would like a unit that folds flat, but of course you could store/transfer items inside it, but don't forget to remove them!!.
