I've often wondered if having the lid on during a boil really makes that much of a difference. I guess it stands to reason that it should boil faster but I just had to put it to the test.
Any guesses before I reveal the results? I'll say this much - - the results were completely unexpected.
Cook System: My Self-Made "Carbon Felt Insert" Alcohol Stove
Cook Pot: The Stanley Adventure Camp Cookset
Fuel: Heet in the Yellow Bottle
Wind Screen: Self Made Arizona Iced Tea Type
Water Temp: ~67 F
Water Amount: 12 oz
Test #1: I started off the test with 12 oz of ~67F tap water with no lid and no wind screen. Results: The water boiled in 5:00 on the nose. Not a bad temp rise.
Test #2: After I cooled down the pot and re-filled with 12 oz of tap water, again at 67F I decided to not only lid the pot during the boil test, but I also wanted to add my self made windscreen to give what I thought would be the best conditions for a boil. Results: OVER 6:00! Shocking. Common sense told me that the windscreen had to be the culprit.
Test #3: Same conditions, this time without the windscreen. Results: 4:40. Now that makes much more sense and that's not a bad time and fuel savings just for putting a lid on the pot. Additionally, my temp probe didn't allow the lid to completely seal so I'm guessing that with a tighter seal even more time and fuel savings would result.
Got a trail tip you'd like to share? I know I'll be diving into alternate wind breaks in the future. I never would have guessed that my wind break was costing me over 1 minute of boil time.
