This calculation does not take into account possible heat losses.
P = Power to install in kW
V = Volume to heat in liters (or dm3)
p = Weight in Kg/dm3
Vp = Weight to heat in Kg
t1 = Initial temperature in ºC
t2 = Final temperature in ºC
Cp = Specific heat in Kcal/Kg x ºC
T = Heating time in hours.
1.2 = Safety factor considering tolerance on sector voltage and resistance ohmic value.
