Thermosiphon Shower Query

[diynewtothis]

Hi everyone, I am doing an internship with a great organisation and the project I’m doing is a non electric shower. I’m going to present the plan of a thermosiphon shower. As I understand a thermosiphon should only have one tank.

I watched a video of an off grid shower and it looked like it used the same kind of set up as a thermosiphon

and I thought it would definitely be easier to have a water catcher tank (so you can just fill water to the bottom barrel than the top) so now there are 2 tanks that connect to the solar grid. Will this be fine? I have concerns of back flow and if it will even work! I do not want to have the top barrel as the water catcher as I’d like to keep it as it without cutting it in half etc.

This is my idea for the organisation and the barrels will be connected to the solar pipes using hoses.
Thank you in advance!

It did not use a thermosyphon.

It was gravity from the catcher tank to the heating tank with a person controlling how much water was allowed to get in to the heating tank,

Then from the heating tank to the shower cabin was again gravity down what appears to be quite a steep hill.

The surface level of water in the catcher tank will have to be at or above the required level in the the water barrel if you want to have water in the barrel.

Thanks so much for your response and I changed it right away, does this look better or will it still not flow? Thank you

Yup, already available. Could you adapt/modify the tech to suit the location/site that you are designing for using local equipment, no reason why not I wouldn't think

Great oner pager here of how it works and the pluses/minuses

Thank you for your response and link I’ll have a read. Yes that is the plan! It will be made using hopefully recycled parts and anything lying around. It will be for a village so we have been told to keep the budget as low as possible.

The set up has mostly taken inspiration from this video and the thermosiphon technique from this video

OK, I see the idea, only things that would need thought through would be temp control and a suitable gravity/mains water supply.

The water supply could be from a large tank above the installation fed from rain or manually filled and there would be a need for a blending mechanism to regulate the outlet temp.

Apart from that all relatively easy to do I would think.
