Hot for heating radiators is fine if you want to be warm. If your faucets are producing water that is too hot for your hands the water is too hot - over heated. Waste of energy if you need cold water to make it useful to you.

Bizarrely, I'm now going to argue for mixing taps.
Other family members wants different water temperatures, plus you want hotter water if you're going to hand wash pans etc...
If you want cooler water, you can use mixing taps to cool the hotter water.
Damn, I just lost my original argument 😂 😂 😂 😂
This is the way. Water heated to the lowest temp needed for hand washing, dishes, bathing. And those with more delicate hands can add cold. Most people set their water temp way higher than they want it and then add cold to cool it down. Madness! (Unless it’s heated with an ASIC!)
I'm not sure my BitAxe would survive under water 🤣
