Required power:
The total power required is calculated as per below:
Pt = A x k x dt x 1.25 x S / I
Pt | = | The required power (Total power in W). |
A | = | The heatable sheath surface in m² |
k | = | The heat permeability of the insulation in W/m°C (for mineral wool = 0.046) |
dt | = | The difference in temperature in °C (the lowest permitted temperature of the medium minus the lowest frequent ambient temperature) |
S | = | Safety factor, is put to 1.3-1.7 depending on how it is exposed to weather and wind. |
I | = | The thickness of the insulation in meter. |
