Whenever the topic of propane heaters come up, there are always dire warnings about the dangers of using them. They are no more dangerous then using the typical cooktop in most RVs. My cooktop is not vented to the outside and that is true of many others. The Buddy heater has tilt and an oxygen sensor to shut it down if it tips over or the oxygen level drops below a certain level. It will also shut the gas off if the pilot flame goes out. The typical cooktop is much more dangerous than the Buddy and I don't see warnings about the dangers of cooking.
