This should boil down to a simple math problem that can be solved by a graph.
You know how much energy is needed to heat a litre of water by one degree, the efficiency of your heating element/system and the amount of water that flows through your showerhead.
🤔💡 Maybe I'll do some checks and measurements tonight to figure out at which point it's better to shower quicker vs cooler.
@sheogorath How long does it usually take you, to find the right temperature? For me its about 3-5 seconds as soon as I have hot water at the tap.
