This calculation does not take into account possible heat losses.
P = Power to be installed in kW
V = Volume to be heated in I.(or dm3)
p = Weight in Kg/dm3
Vp = Weight to be heated in Kg
t1 = Initial temperature in ºC
t2 = Final temperature in ºC
Cp = Specific heat in Kcal/Kg x ºC
T = Heating up time in hours.
1.2 = Coef. of sec. considering tolerances on sector voltage and ohmic value of the cartridge.

W/Cm2 = Surface load W/cm2
P = Heating cartridge power (W)
S = Surface area (cm2) = diameter (units in cm)
| W/Cm2 = | P |
