This Coleman stove has two 10,000 BTU burners that have independently adjustable flames that let you simultaneously boil water (on HIGH) or simmer (on LOW) whatever it is you desire. You can hook in a single propane cylinder tank that gives you 45 to 60 minutes on HIGH depending on your atmospheric conditions. This is a Coleman PerfectFlow stove that allows regulation of the propane pressure so some use and experimentation will get you desired results. It is a small unit, but it is very versatile and well-crafted. This Coleman stove has adjustable sides that allow for larger cookware and/or use to control temperature. Matches or such are needed to ignite the propane fueled flame. The bottom line on this unit is that it can really throw out heat and it is easily regulated.
