I also had a question regarding the burner itself but generally how long does a 20lb tank of propane last while using the burner continuously?
We are user of the stove ourselves for last 20 years. A 20lb propane tank usually lasts 3~4 months. My wife cooks 1~2 dishes a day on the stove. We have 2 tanks, a full tank sitting ready to swap in case the 1st one runs out in the middle of cooking.
