Probably related to the recent bank fears in the US and higher than normal demand for cash if it was a recent withdrawal. Or somewhere a inventory was taken and older cash was moved to the front for distribution.

You know how something just gets left at the back of the cubbard/drawer because you keep restocking at home? That is probably what this is. Somewhere at some cash depo (bank or otherwise in the distribution system for ATMs) these were sitting "at the back" in the inventory and higher than usual ATM witdrawals for example made them finally enter circulation.

The Dutch are such fanatic warmongers they have been trying to pick a fight with Atlantic ocean for a few centuries now.

Like, give it a break. Eventually she will wake up and drown you all :(

> Unless you live in a temperate climate heat pumps have to be really oversized (3x? If it gets really cold) to work in winter.

I think people are stuck in the past when it comes to heat pumps honestly. People install even air based heat pumps up here in northern Sweden.

Yes, if it gets extremely cold you will probably be using some direct electric heating as well. But how often does it get to -15C in the Netherlands? The level where good modern heatpumps really start to struggle. For a typical Dutch winter heat pumps should be no problem what so ever from a tech standpoint.
