Your conversion took a wrong turn somewhere. BAC is just percentage, promille is parts per thousand. So to convert, multiply by ten. Making it 4,2 promille. Really shitfaced. Very potentially life threatening even if you are not driving.

A truly horrifying prospect.

Radiant heat is great, and heat pumps absolutely can and should be used to supply the heat. Radiant cooling, while technically possible, has a lot of downfalls, forced air is your best bet there. The same heat pump can be used for both though, just need a valve to switch between different supply loops.

USA had the same thing, “Cash for Clunkers”. Some of the cars we were better off getting rid of. Some of them not, whether because they were rare or classic, or old but still more fuel efficient than a truck or SUV. Sure increased the average price of a used car though.

Of course. Those resources are just a much larger impact percentage wise on an appliance replaced every two years vs 25.

More water and energy efficient to run, yes. If you have to replace them every couple of years the resources used to make new ones need to be included too though, and that will have a big impact on the comparison. That said, I have had a modern front load pair for at least 5 years now, no issues.
