eyeguy,
CCH is correct as to this being quit a bit smaller than other stoves. The 1st version brought just under a liter of water to a rolling boil in 30 min. This 2nd version has better surface contact so I expect boil times of 20 to 25 minutes which is pretty comparable with a Kifaru Para stove.
Other cykinder stoves I have built have been close to flat topped for boil times. In my experience, a damper or damper plate is more important with cylinder stoves to direct more heat to the cooking surface.
Boil times may seem kind of slow when compared to a gas stove, but with a wood stove you are just sitting around stoking it and enjoying the shirt sleeve warmth.
Chris,
The door is cut from 20 ga stainless. I could have cut. probably another ounce by using lighter material for the door, but the 20 ga with the spring latch makes for a nearly air tight stove.
