I tried using a tea light stove yesterday, and I was not impressed. I used denatured alcohol filled all the way to the top. It burned for 14 minutes, and the water never boiled. I am in Phoenix, elevation is around 1500 feet. The ambient temperature was approximately 60 F. The stove was in my garage and out of the wind. The water quantity was 24 oz., and the water temperature was about 70 F. Is this the performance that can be expected with the tea light stove, or was there something I was doing wrong.
