Reply to comment by squeezy102 in LPT: If you want to check the water temperature at the tap, touch the metal tap end instead of putting your hand under the water. by Independent-Aerie-42
The tap couldn’t be hotter than the water. The water sets the max temperature.

I’m not arguing that. I’m arguing that 180 degree water and 180 degree metal do very different things to skin.
I don’t know what it’s called, maybe specific heat capacity, maybe thermal conductivity, I don’t study this shit - but I will tell you from experience that there are temperatures where the water won’t burn you but the metal will.

It's the thermal conductivity. Specific heat capacity is the amount of heat energy an object can hold per unit temperature. It doesn't really matter in most cases as it doesn't take much energy to burn you. Also, water has a very high specific heat capacity - much higher than metal.

Ok cool. I don’t wanna give unsafe advice, and I can’t get a clear answer from google so I’ll remove the tip. I was just trying to stop people getting wet hands for no reason. I don’t know what boiler you have, but I was talking about temperatures around 40 degrees Celsius, so no one’s gonna get burnt or scolded.
