Hello, I will soon build an outside shower using a rocketstove.
I am thinking about 4 possible systems. I would like your help to find out which one is the best, pros and cons....
This is what I want to achieve:
- a system which is safe and simple (there will be different people coming over and using the shower, everyone has to be able to use the system without my supervision, so everything has to be straight forward and it has to be impossible to trig the system into a potential bomb by opening or closing in accidental way the valves)
- a system which delivers water to one shower only but it can give hot water for many people (about 15), one at the time, without waiting much between one person and the next.
The shower is going to be built in a remote area, so no electricity and no main water. The water comes from a cistern on a high spot, so I am using the force of gravity.
The drawings I posted should speak for themselves. The numbers are in meters and liters.
Here are my comments and doubts:
System 1 - I like this system but it can become dangerous if someone by accident closes the valve 1. Is there a way to make sure this will not happen?
In the case of valve 1 open and valve 2 closed, can the steam potentially developed inside of the small tank (inside the rocketstove) climb the pipe
and discharge itself into the big cistern, so creating bubbles? Or do you think that the pressure of the water of the cistern is too great therefore
turning the small tank into a bomb, like if it was plugged to the main water system?
System 2 - This system is safe, but I am not sure it can deliver enough hot water. It is quite expensive to buy the copper pipe.
The internal diameter of the copper pipe I found is 15mm (0.59 inches). Will this pipe deliver enough water to have a decent shower?
System 3 - This system is safe, but the small tank has to be placed higher than the shower but lower than the cistern, it will look like a small tower. The heat
riser is going to be quite long. I am not sure that the small tank will deliver enough pressure to the shower.
System 4 - This system is safe but not very comfortable. Moreover a good solid structure has to be built above the shower and a stair to reach the top. I don't
know much about hand pumps, I am thinking that perhaps the pump can work even if I put it on the floor and pump water on the bucket above the
shower.
Here are the drawings:
