[suggestion] about warm water

[Trixi]

my thoughts of your heating system/warmth need/hot water and so on.

transport of hot water:

you mentioned in your update video, that you want to do an extra transport system for hot water. Im against it. I dont wanna build all pipes double, just because i need some hot water. In most cases hot and cold water pipes are installed paralelle. So my suggest would be that you could use the already installed pipes and just save, if its a hot or cold water flowing. The solution could be, that you build a heater and that you have to connect to your pipe system.

then an idea for the showers:

i think it would be suit to this system, if you have a prisoner thats showering, his warmth need will increase stronger if i showers cold. but if a shower is connected to hot water, the warmth need could be easier fulfilled with the shower.

Another thing. if somebody takes a shower, the temperatur of the spot should be slightly increased. If one shower it shouldnt have a big effect then, but if you plan a shower time, with lots of prisoners showering simulataniously (with hot water) the shower rooms gets automatically warm, even if its not radiated.
