I love using my Mr. Heater Buddy Flex Heater. It provides great heat in the hunting blind, and is always on hand in the winter to provide emergency heat if the power goes out. However, one drawback to any type of heater like this is that it can quickly burn through a small bottle of propane. In this video I show you how to use the 5 foot extension hose and connect a 30 lb tank of propane to your heater. This is quick and easy, and works really well. I hope you find this useful!
