On Board Water?

Will be finishing up mine as the weather warms also.

 

I have have thinking of doing and OBW setup and this is the best thread of have seen on any forum. Seems like you have answered all of the right questions so I don't have to. Have you made any progress since your last post?

 

well, no. no physical progress.

I have been waiting to get sliders to turn into air tank sliders. Then was going to convert my OBA tank (5-7gal Aluminum) to an OBW tank. - I have an High Output DI/RO system I was going to use for this to make 'pure' water for the setup. Drinking in one tank and regular potable in another. - Thats one Idea, Might just fill the whole system from the same port.

Jeep has some interesting bumpers that double as water storage. I like the idea. just do not want that much weight that far back from the axels.

 

I've added a Lifestraw Family purifier to my gear. Now so long as I can find a muddy ditch to get water out of, I don't have to carry a bunch any more. It works great, doesn't take up much space and filters about 2-1/2 gallons per hour.

 

Where would you install the plate heat exchanger? I would prefer it to be as close to heater core hoses as possible but there is not that much space where the hoses come out of the firewall.
Also which hose is coming out of the heater core. Is it the top or the bottom? I haven't tried to hard to see where the hoses come from to narrow it down and I figured it would be easier to just ask.

 

I quoted all the posts again from the other thread to try to keep all the info in one spot for people not subs to the other threads.

Spencer, take a look at this.

If you read back a couple pages, it looks like the EXACT unit someone else had used. Meets all your criteria too. Not cheap, not plastic, durable etc.

 

here is where "Tweek" mounted

 

Found the mixing valve and a 40 plate heat exchange on Amazon! not too expensive either.
found the heat exchange with 1/2" barbed fittings..... someone mentioned the truck heater core was 5/8" - if i use the 1/2 barbed with two good hose clamps, it should be fine.... right?

 

I've always used bota bags for fresh water. You can drink out of them, carry them easily when hiking since they hug your body and don't bounce, hang them here there and everywhere on your camping vehicle, very durable, I still have some I've used for twenty years. http://www.walmart.com/ip/Stansport-2-Liter-Bota-Wine-Bag/11962970?action=product_interest&action_type=title&placement_id=irs_top&strategy=PWVUB&visitor_id=80838374491&category=0%3A4125%3A546956%3A4128%3A1080844%3A1080865&client_guid=5f281a32-a3ec-44e6-8c12-650f7c8da5ff&config_id=2&parent_item_id=13848620&guid=4e6130b5-f67b-45a7-8da4-7479c9904719&bucket_id=irsbucketdefault&findingMethod=p13n

Bota bags can be stored anywhere and they don't produce mildew or bad taste, require no cleaning. The simplest method is always the best.

Two liters of fresh water from one bag goes a long way. For cleaning, you pack the cleaning wipes you get at BBQ joints, they cost about $0.10 apiece. Like this

$33 Royal RF1MB Moist Wet Wipe Towelette, Individually Wrapped, Package, 1000 Count (Pack of 1), White

Hmmm....
Now If they made huge ones over 5 gallons that'd be awesome to stock up on water when I found it & shower with it later.

 

Heck, just buy four bota bags. They really do work well. Like I said I still have some I've used for twenty years. Neatsfoot oil on the leather to keep it from drying out and cracking. It's a simple, cheap and very effective way to carry water for mobile applications.

The cleaning wipes are dynamite also. You carry them in your pockets so they're body warmth. Sure beats trying to wash with cold water and soap.

Is this what u are looking for?

Haha ok so we're both maintaining threads about on board showers under titles that address different issues... On board water is one thing & exhaust heated shower is a very different concept yet they both now describe how to use a heat exchanger for a shower.

I say one of us starts a new thread titled HOW TO INSTALL ON BOARD SHOWER or something glaringly obvious.

 

The purpose of the OBW IS the shower and drinking water. That's why I started combining it all in one thread a long time ago.

For on board air, OBA, the title isn't "trail pneumatic tools" - using an all in one title encompasses the many options that way it is easier to reference.

 

Where can I find the full thread?

I just reviewed this thread. I really like Josh's setup which was listed here from a post from last December.

I may try and replicate that.

I have tried the L5 Eco Temp, Solar bag and vehicle mounted showers, and I also have a Helio pressure shower. They all work given the right circumstances. That said, they all have shortcomings too. Too much wind (L5), not enough sun (solar), heating water on a stove and pouring it, (too much manual work).

So, I think I might delve into the vehicle mounted, heat exchanger option with tank. What I like about Josh's system consisting of two pumps is that it's relatively simple and controlled with manual switches. One place I see for improvement is, if a temperature controlled circuit could be introduced to control the recirculating pump. That would make it perfect.

EDIT: I thought about it some more and perhaps the same result could be achieved with one pump and a way to direct the flow of water. For example, recirculate water to desired temperature with circuit perhaps; when shower is needed, turn valve which would direct the water to the shower outlet.

EDIT #2, I think I found a decent digital temperature controller for a project like this. $32.50, +12v DC, temperature range is -50 to +100 C, and temperature probe is 10', and relay contact capacity is rated for 10A.

 

Nice work crom
