Shower / hot water system

Thanks again for the info!
I was just poking around under the hood of the XJ with the Shurflo in hand. It's pretty tight under there. To simplify plumbing and space issues, I'm considering running just one outlet controlled by the anti-scald. If I want cooler water, I just shut the engine down. If I want cold, I'll wait Thoughts?

Just had an awesome idea---what about a couple of diverter valves in the coolant lines to and from the heat exchanger that would allow you to bypass the heat exchanger?

My reasoning is twofold---first, you could have cold(er) water if you wanted from your one output; and, second, if the "rumored to be fragile" plate style heat exchanger fails, you can bypass it easily. It actually may make more sense to run in bypass normally.

Thoughts?

yes bypass makes more sense than 2 outputs, i just didn't have room to easily get a bypass valve and handle into my intended "control panel", and i didn't want to spring for this: http://www.davis.com/catalog/product_view.asp?sku=0861774

i'm looking at setting up a permanent on-board-tank soon and so several aspects of the design may change on mine.

also, if you have a really old vehicle, note that coolant only flows through your heater core when you have the heat turned on, so you can control the temperature based on the heater settings. on almost all newer vehicles, the heater core is "live" all the time though, and you need dual outputs or a y-valve to get cold water out of your system.

This is how we plumb many of the Helton installs, for example on my 04' Tacoma I use my temp control switch on the dash to regulate the temperature of my shower, works really well and allows for quick & easy adjustments.
