Sold. Past tense. I ordered one up and he got back to me and said the place that was making them was vandalized and was not planning to start making them again, at least for a while. Maybe if enough of us speak up? He has other choices, but none that intantly set them selves up!

Now that is what I am talking about. For a long camping trip you can not beat a hot shower. Bring the wife and presto instant shower scene.
It could even smoth over making your other mad at you.
 
Most of the homemade heat exchangers that I have seen are made out of Copper tubing and piping. Here's the question....does the copper react with Anti-Freeze and contaminate the coolant? I am using factory Toyota Red Coolant and I am very curious if the coolant corrodes the copper and thus gets contaminated. Anyone know. I am very close to building on if these setups but want to understand this detail a bit better first.

Great thread by the way!
 
you could run a piece of threaded pvc for the outer with screw on caps and run aluminum tubing on the inside instead of copper if you were that concerned
 
I think that PVC bursts at a much higher temperature than copper. This could be a bad thing in the winter time as low temperatures will strain all parts of the cooling system and PVC might burst whenn the coolant reachs ~10 degrees as opposed to ~-20 for copper. I don't think I'll be using PVC for this reason as my truck sits for periods of time in remote areas in super-cold weather. Also there is some concern with mixing Aluminum and other metals in a closed loop cooling system as the metals can react with each other and the coolant corroding some or all parts. Not sure how this will play out for the block, radiator etc. but my understanding is that the fewer metals introduced the fewer likely problems will result. I did do some research and it appears that the additives in the antifreeze do prevent against copper corrosion. Now if someone knows off the top of their head specifically what metals and materials the coolant comes in touch with....I drive a '96 FZJ80. Thanks

Also as I remember it, Toyota RED is Etylene Glycol which has great corrosion protection so I am not sure if I am overthinking this whole thing or not.
 
you might look into some of the tube in tube heat exchangers sold for things like biodiesel applications...
there is a place- greasel.com I think- that sells some tube in tube that is designed for heating fuel, but could probably heat water.

personally, I've got the Glind shower setup in our 60 and can't say enough good things about it. Works great. Clean. Easy. Good stuff. www.glind.com.au

you wont be wanting to use 1/2" soft copper inside the tube. too big.

i made my own, dont have a pic of the coils, but its almost excactly the same as what yankeetoys did EXCEPT,,,,

i used 2" copper with caps and barbs, then i coiled 3/8 soft copper around a broomstick to fit inside the 2". it works great, with the engine at operating temp it can make water warm enough from a cold stream to shower comfy.

Rhino,

I was planning to do an inner coil as you describe, but did you have any trouble w/ the tubing crimping when you wrapped it around the broomstick? I was wondering if that wouldn't flatten it too much--if I'd need to use a tubing bender.

As a general note, from all I know about biological counterflow exchange systems, I plan to have the coolant flowing through the outer tube in the opposite direction to the water inside the coil--you get much more efficient exchange that way. Can't wait to get started on this--great thread! :bounce:

I read an article about bending the tubing: Take table salt and crush it to a fine powder in a blender or spice grinder. Cap one end of the copper tubing...using a funnel fill the tube with the fine salt powder; cap the other end. Carefully bend the tubing around a broomstick or whatever; you may, to prevent surface deformation, need to make/use a wooden mandrel to bend the tubing. When completed empty the salt, rinsing with hot water...

I wish someone would make a shower/toilet enclosure similar to the OzTent setup that David Dearborn sells tho! It'd be nice to just throw it up in the air and it'd pop up done! I have a cheap on with poles that "SUCKS" really, takes way too long to setup.. Still lookign for a better solution for the tent..

also.. Didn't find a spare at the house last night.. Sorry! Can't quite make it across the garage to the Fj62 either to pop the hood!

I have one of those square shower enclosures that hang. I
clamp a telescoping golf ball retriever pole to my roof rack
and when extended it hangs the shower stall perfectly next
to the truck. If tree limbs are handy I'll use them, but the
pole works great. I use a R&N system for the shower.
 
While flipping through my archives I came across these three shots I saved from a really old thread on the Pirate board that talked about onboard showers. I don't remember who the owner was, but the setup was really clean!

didn't think about the burst temp. i live in the deep south, it's not an issue here.

Chad,

Got anymore details on the heat exchanger you used?

Their site has lots of usefull stuff. If I had to do it over again, I would just get the heat exchanger. I ended up using custom mounting brackets and sourced my own hoses. I also like the idea of having an underhood mounted pump and I was not happy with the shower in the kit.

I know that few people are mounting the pump under hood. Even though during usage, the hood may be left open but is there any concern for the extreme heat that pump will experience during its lifetime? I didn't see any specs in Flojet's site for the environment. Regardless, these things normally don't see the temps that an underhood install will see. Thoughts?
