Awesome kit! Running for that long and only needed a short, 20min recharge is very convenient and means less time mucking around. Plus, it keeps things in order and saves the pump/ battery from getting a bit messy. So many cool ideas on this thread!

Like barrel01 mentioned, the system will be completely automatic (depending on gas situation) and the HOTTAP will start heating up the water as soon as it senses water flow. Any open/ close valve will do the trick here, so, you could exchange the shower head for your tap and have no issue at all. An idea may be to fit a T-piece on the water outlet (on the HOTTAP) and run one line to your tap and the other to your shower. You'd only be able to use one appliance at a time, but this would make things a bit smoother.
In terms of leaving the gas on or off, I'd leave it off. Like Fizzie said, it is really down to how you want to do things here. Let me give you a couple points as to why I recommend leaving it off:
- It is safer. I'm always one to make sure the gas is turned off when I'm done with the HOTTAP, or my BBQ, or any other gas appliance. It doesn't take long to turn it off and I don't want to take any risks. I'm not saying anything will happen, but I think it is better safe than sorry.
- Let's say a fitting blows within your set up and water starts flowing through the unit, engaging the burners - you'd run out of water and gas in this situation. I also turn off power to my pump for this reason. If I know I won't be needing hot water for a while then everything is off.

We once had 12LPM and 18LPM pumps with 40PSI, so, these were not operating at mains pressure. I can't recall the pumps I may have been referring to unfortunately. Our FLOTAP6 is at 60PSI, but this still would not be enough for your reverse osmosis unit. In saying this, I suggest using a different pump for your reverse osmosis system (not using the same one for HOTTAP) as the high pressure may lead to hose swelling and fittings blowing. Even though I do believe it is beneficial to take items that have more than one use, this situation is a bit trickier.
With the gas side of things, an idea might be to look into something like this:
