Older homes with tankless water heater experience the opposite reaction: when someone flushes a toilet all the cold water rushes there. And you get some: hot - hothot - boiling! water.
Lol, in Germany those are only installed in shitty old houses with crap plumbing. They drive up the electricity bill like there’s no tomorrow. Just install adequate plumbing when building a new house and never deal with this problem.
Newer homes have tankless constant water heaters and it’s the greatest thing in the world.
