Studies show that the average shower takes 8 minutes and consumes approximately 96 liters (12L/min) of water depending on the flow rate of the shower. An energy-smart shower uses up to 2,2 kWh and does not exceed 75L of water regardless of temperature.

Specific heat capacity
Q = m * c * (T2 - T1)
Q = 8068 kJ
Liter for specific shower temperature
m = 8068 / (4,2 * (T2 - T1))

LED light will effectively display when in moderate use, to bring awareness and to remind the user to turn off the water while soaping. Example: 60L of 40c water for 5 minutes (12L/min).
