That's 70ºC, 49ºC (120ºF) is usually plenty hot enough and the recommended temperature. It can actually cause burns with long enough direct exposure at 50, 70 is madness.
In the US the standard safety temperature for the water heater is 120° F
You don't need it higher than that unless you have a small tank and use a lot of it. Tankless is 120°F.
I don't know where you got 70°C from.
You said:
That's 70ºC and I'm agreeing that it is a ridiculously high temperature to keep a water tank at. That's instant second degree burn temperatures, completely unsafe.
Ohh I see now.
Yeah 160° is too hot. But people do it. Small tank multiple showers needed. You can stretch it.
I was saying for people that have their water too hot. The regulator inside the US mixing valve has a stopper so you can't go to max hot. That's all the piece inside does, stops you from turning the valve more. Doesn't help reglate the temperature. Someone in comments said their regulator is bad and I thought it was OP.
I keep mine at 145, because I fear legionella.
