I... Genuinely only realizing this now
(lemmy.world)
For real. Everytime I get in the shower I end up having to point the showerhead away and cower from the cold water and I could have just turned it on first?
I've never waited for more than five seconds for the water to reach acceptable, and 10 seconds for the set temperature (40° max in my case). Always had and used a tankless water heater.
Which has a high initial cost + yearly maintenance.
250€ and biyearly maintenance. For that you get instant hot water.
That does not track with what I've researched, at least not the price. I'm sure you can get away with not maintaining things frequently — although I'm not sure I want to take that risk with something my water flows through.

227€, same specs as the one currently powering my apt.
I just asked my dad, how often he maintains the one in our bathroom. He was surprised that was even possible. There was actually never any change in temperature, flow rate or noise in the 10.5 years it's running, with the second highest water hardness.
The only more expensive part is the running cost of 18-24 kW
