T18skyguy,
Just a question if I may. If you keep the water heater set at 105 degrees so you can bath without adding any cold water to the mix, is the water at the sink hot enough to wash dishes with? 105* is probably hotter than I like my showers, so I'm just curious. The tankless system we have in the house is set at 122*, and I think it should be a bit hotter for dishwashing. We keep it set low at 122 so in case any of the "little kids" visiting hit the hot water at a sink, they won't scald themselves, otherwise I'd bump it up a bit. 105 seems a bit on the cool side, but I guess it depends upon what you're used to.

I don't know how high the thermostat will go, but the beauty of tankless is you can set it what ever you want and within a minute it's there. The issue would be if you want to do dishes while someone showers then that would be a problem. The rule for dishes would be the same. Set the temperature and turn on the faucet and leave it. Tankless does not like on and off. Where there can be a problem is when you want to trickle the water to rinse plates. If it doesn't get the flow the tankless shuts down. Tankless is not so good for people who do a lot of dry camping. It's not made to save water. We use 105 degrees for everything including dishes. I did try setting it at 112 to shower but it was way too hot for me. I don't miss the campground showers, but my wife and daughter still use them out of habit. One important thing to remember is that static pressure is always higher than running pressure You need to have the static pressure high enough so that the running pressure keeps the tankless happy. I find running pressure to be about 20 PSI lower than static. I can't say enough good things about the adjustable Rinaldo pressure gauge. Very high quality and go it on Amazon.
