(Apologies for repost, I had put this in the forum for heating but this is more of a cooking stove type)
I am new in the forum and on the rocket stove world. Still starting to look at solutions for heating water for shower on an off-grid site where I will camp with a group of 5 people.
The goal is to heat water for an outdoors bucket shower, meaning i need 15 L of "hot" water for one shower. Apparently the ideal temperature for showering is around 45ºC.
What do you think is better: A) to heat 15L at a time up to 50ºC and then transfer the water for the bucket in the shower, or B) to boil 5L of water (100ºC) and add 10L of cold water (15ºC). It really is feasible to transport the 15L from the place where the stove will be, to where the bucket is. I would intuitively think A is better because there should be more heat losses after some point in solution B? Am I wrong?
And regarding expectations about time? I didn't find so much info around. In this post the author mentions it takes 25 minutes to boil 5L of water. Is there any other posts you recommend me to read? Any spreadsheet around that could be useful for me?
Honestly I would appreciate a lower time for taking all the showers. Assuming solutions A and B would take the same amount of time, I would need 2.5 hours to take 5 showers. So I saw a third, more complex possibility: C) something like www.youtube.com/watch?v=B9BQGamXLMk. They mention that heating about 120 liters of water would take 2 hours and would allow 10 showers. My question is whether heating water for 5 showers would take half of that time or is there any scale issue? Could I assume that when heating water only for one bucket shower it will take roughly 1/10 of the 2h?
(Plus solution B would allow me use the same stove to cook soup as well. I know I am mixing apples with oranges, but it is more simple and versatile, right?)
