Whatever the temp is in our brand new airstream, it's too hot. Relying on mixing valves to keep people from hurting themselves is a mistake as far as I am concerned. If I could turn this new one down, I would. But there is no temp control on it. I've read that I can replace a thermistor and lower it, and I intend to do that at the first opportunity. I don't need THAT much hot water, and less hot is just fine with me.
If I had been able to spec a water heater, I would have gone with an older model with temp control.
