Both need to hold their temperature as long as possible and get up(or down) to temperate at some balance point between speed and efficiency. I want my provider to even it out and set a reasonable price between the variable extremes so I don't have to think about it.
The advantages are a lower rate and a guaranteed 8 hours straight on-time per day.
Of course, the actual implementations can (and in many cases have) been a lot worse than that.
You're not thinking capitalistically enough.
The fact that IoT is still a running joke and just a tolerated parasite to lower the sticker price at best is proof that the data is garbage because none of them are making much money off of it. Until they have an actual monetiziation plan for the data it is plain magical thinking.
"People mostly increase demand on their hot water heater in the early morning, evening, and night for showers dishwashers, and laundry on a semi-weekly, weekly, or bi-weekly basis."
"Well I could have told you that without spending six to seven figures on unnecessary expenses on a product line!"
Call it what it is: exploitation.
Greet and fraud are encouraged, if not idealised.
That’s not capitalism fault though.
Every other form of economic policy has the same problem, so it can’t be those systems in and of themselves that are the sole issue.
Might.
And probably trivially more, especially when you factor in a software update bricking your fridge and the manufacturer has conveniently disappeared / gone bankrupt / changed hands so many times no one knows who supports it.
You’re assuming an ideal world, which can’t possibly happen.
This was more of a method of managing peak load, however, still seems applicable.
So whether it's a tank of 80°C water or a tank of 65°C water make no difference to the 38°C water coming out of the thermostatic mixer in your shower.
I don't have the regulations to hand but it's enough to bring it to a high temperature once every few days for some period of time (to kill the bacteria that cause legionnaires disease).
