Central heating pumps run for several minutes,
if the pump motor was the source of the RFI your Wi-Fi link would also be down for several minutes.
There is an electro-mechanical valve which is only activated momentarily (seconds) when the pump motor starts.
So a faulty electro-mechanical valve could be the source of RFI and your momentary loss of Wi-Fi, (and the banging).
OK, so electro-mechanical valve noted..

Of course, if you try it in a freezer, and the freezer is in different stages of its cycle, each time you do the experiment, you may get the unexpected answer. Also, warm water may trigger the cooling pump to operate sooner, which should also affect the fairness of the test..
But there's no thermal inertia in the simple setup you are implying.
But if the warm water and the cold water were to go into the freezer at the same time alongside each other, the cold water would definitely win?

You could scrape some of your skin off as well.. Mind you just a bit, cos too much and it will reveal the red layer under and it will sting!
