My target user? well........I want to limit the shower times of a few

results.

Same here. They either don't shower for days or shower for 30 to 45
minutes.


I agree that I should either turn off only the hot water and/
or first limit the flow as a warning. Turning off the water heater as
mentioned in a reply won't produce the results I'm looking for. The
water heater is a 45 gallon tank style.

You need a electrically controlled valve to turn off the hot water
line. Sprinkler valve might work, but not sure if it will be a problem
with hot water.


I recommend a valve for a washing machine or a dishwasher.
Inexpensive, available and known to be able handle the job, probably
120 Vac though, so an SSR is needed to control it.

They will NOT handle the job, very large pressure drop at low flow rates, bad choice, wrong technology...
