heat exchanger

basically a device that has two coils in it,one for the hot engine coolant and one for the shower water,an electric pump to circulate the shower water

Traveling.  It leaves you speechless and then turns you into a storyteller.

Creating the heat isn't really that much of an issue for me. In my application I will be moving daily and depending on the method heat exchanger or my little Truma having access to water is an issue. I found I went through a great deal of water in the dessert. In my home province or in Russia water wasn't an issue. Warm/Hot water was. We used the exchangers in Russia and took showers in the morning and night. Quarters were tight. The diesels never shut off in Russia so we just loaded a trough with snow and angled it with a hose above an acumulator tank. Tank warmed the snow and it melted and added water to the accumulator tank which cycled through the exchanger. The reverse issue temperture wise can be painful. Usually that initial cold blast of water that gets warm. With exchangers it can get too hot very quickly and we humans are not that good at determining tempature on the skin. Think back!! But a ten minute shower is super nice option to have for the time you have plentiful water. You need to be careful with exchangers. Pump psi can be 50 and so do not save a buck on hoses and fittings. We had three failures in the years we did Russia. All of them fittings. This can send a jet of scalding water and murphy says you be standing junk out right in the perfect spot.

Don't buy cheap exchangers if they clog then the pressure has to go someplace. Think above senario but with steam.

We kept them in the engine compartment. With quick release valves for source water and accumulator tank. We would drain the exchanger with the last shower by removing the source water and letting the shower pump run dry. So get a pump that can be run dry as the exchanger could freeze in the engine compartment. Depending on the style thi could damage a weld and leak. I would be really hesiitent to install into the rig. This being said my current rig is being built with a 30,000 btu exchanger style heater for warm air. But the pump/expansion tank and exchanger is outside the rig and only the fan exchanger is inside and at a low point, with a drain. Valves isolate the fan/exchanger and draining the unit is not required as it is filled with gylcol and not water.

I've played with recyceling water used in the shower and cleaning it with a UV and filter medium. I have yet to be able to call these tests sucessful. We lay in bathwater and call ourselves clean but the idea of using recycled water to shower is somhow repugnant. Now showering in someone elses water I get. But five gallons for a long shower used three times sounds like heaven. 2 gallon quick shower or 5 gallon used three times? Get the thinking on this?

Here they use these http://www.sunflower-solar.com/index.php...uler_id=61

up on the roof. They are strong but I wonder the surface area and longevity on a mobile roof structure. Never had cold water or heard the Genny go on yet.

Out there in the desert, and on other camping trips, I have used a pump-up garden sprayer (with kitchen sink spray nozzle) and just left it out in the sun for several hours until it was warm. I step inside my little pop-up privy tent, and I'm fresh and clean in about 5 minutes. 

Of course this wont work when its cold, but then again, when it's cold, we generally don't sweat as much, so showers can be simpler and less frequent, for me, anyway....sometimes to the extent that a spit-bath and/or a small spray bottle with water warmed on the stove can get the job done.

I think people over think showers, at least I did, initially. I felt like I needed a shower, a creature comfort I wasn’t going to live without, something warm to stand under to wash. I bought one of those submersible pumps like a bilge pump with a hose and a nozzle, I used to throw it in a bucket that I heated in the sun or boiled on the stove and showered outside, It was ok but since it burnt up a few years back I never replaced it, I just use the warmed up water in the bucket pouring it over myself with one of my pots, It works great, feels just as nice with less hassle and I end up using less water.
