On demand recirculating works reasonably well but only for people who tolerate it. Push button, wait 3 min, water hot. It works for me but I know it’s way too much trouble for other people. It saves water and energy.
hot water circulation systems should be more common
That just sounds like a waste of energy. Why not have the water heater right next to your shower, so that there’s no wait? It’s how it was set up in my parents home. Really enjoyed that setup, never had to wait for hot water.

If you have a consistent schedule, you can also use timers for those so you don’t always need to remember to run it.

Oh, yeah, that makes much more sense actually. Now I kinda want that setup, but I bet it’s expensive.

I assume electric showers are pretty rare over there? We’d have like a 16mm2 cable ran to the bathroom for a 10.5kW shower. And with one of those it’s practically instant heat, and enough to heat high flow.

I’ve never seen one. We’ve got on-demand water heaters that feed entire homes, but the electric versions are notorious for breaking a lot. The trend is toward heat pump hot water storage tanks that cool the air around them and put that heat into the water tank.

Thanks for info, good to learn.

Because the kitchen isn’t always wall to wall with the bathroom?

That’s still confusing to me. My parents had the water heater tank in the bathroom, between the shower/bath and the sink. The kitchen sink had a separate small water heater.

Most houses in the US have a single water heater, usually in the basement or utility room, with pipes running all through the house.
