There are a couple of problems with this set-up. The greatest problem being
if you use that holding tank for both drinking water and water for a shower,
the hotter temperature encourages biological growth. I don't think it would
be long before you would have all kinds of things growing in that tank.
Trying to keep the coils clean without having to completely disassemble the
thing every time you clean it would present a major challenge. Lastly, is
convenience. What if you want shower in the morning or do your dishes
late-night, after the van has been shut off for a while? Don't think I want
to burn up a bunch of gas heating water.
You then have to figure out a way to get the water to a shower head. I don't
think this would be a major obstacle. Probably just insert a tee in line
with a shutoff valves to divert the water one way or another. An on/off
switch at the shower head would be ideal. To me, it's just a lot more
maintenance and things to break.
Having a way to regulate the temperature on demand would also be nice as
your body acclimates to the temperature you tend to want the water warmer.
All of these problems are solved very nicely with the Coleman hot water on
demand. The biggest complaint of course is the thing is just too big, but
it's rated at 30000 BTU versus the Zodi at 10000btu and the dual burner
one is at 20,000. The problem with the Zodi is the pump and flame are
controlled separately, so it's hard to shut it off in the middle of the
shower without getting scalded when you restart it-- just not very
practical. The smaller on likes to tip over as well.
Again, the Coleman takes care of this problem and also has the ability to
deliver 160° water for coffee and tea or just warm up some dishwater.
Sometimes, simple is better though and heating a 5 gallon bucket over the
campfire or boiling some H20 on the stove and mixing with cold water to
taste, and then using a portable $20 pump takes care of the problem nicely.
