1. Time needed to heat the water in the water heater.
Т1 - initial water temperature (entry into the tank, water is most often with temperature 12-13 degrees). Т2 - desired final temperature of the water.
Must: 0 < Т1 < 100
0 < Т2 < 100
Т2 >Т1 Set the color fields!
H - time in hours and minutes. W1 = 0.0011864 KWh - to heat 1 liter of water by 1 degree. T - degrees to increase the water temperature. Wn - power of the electric heater. Q - liters of water.
