How does cleaning of the heat exchanger work? From my experience with Jaccuzzi-style baths anything that recirculates bathwater gets very nasty very quick and is a nightmare to clean.

in Japan you tend to shower & wash yourself clean _before_ getting into any bath. In the west people don't do it or do it very half asset. And tbh. a lot of places have combined bath/shower so you kinda can't even do it Japanese style nicely.

That alone probably will make a huge difference in how often you have to deep clean it.

> you kinda can't even do it Japanese style nicely.

I mean you can as long as you make the bathroom a wet room and shower outside the tub, which is exactly how the Japanese do it.

my point is most _rented apartments_ are not setup like that and do not provide a reasonable path to have it

most owned apartments also are not build in a way where it's easy to retrofit. So if you don't do a "in depth" renovation anyway, its often just not a good option from a financial POV. Especially if you have to reroute plumbing (for the floor level wet room sink), especially if beton floor or pre-existing floor heating is involved.

Yes. But then those wouldn't be the places which GP was talking about, where the shower head is set up so you stand in the bath tub to take a shower.

I’ve used a bunch where the shower head is on a hose not fixed to the wall. Usually with a two-way faucet.

The biggest issue in the west is the room being wet to start with.

    The copy of The Garbage Collection Handbook at ~/Documents/Books_on_vm/ is the 2023 second edition, and it covers G1, ZGC, and Shenandoah by name with dedicated sections. What follows is read directly from that PDF (page numbers are the book’s own page numbers, printed in each page header — the PDF file’s own page index has a fixed +37 offset from these, front matter accounts for the difference).

Why should I keep reading an article if author the couldn't be bothered to read it themselves after copy-pasting it from a LLM?
