Solution
Result
Average heat flux generated by the planar heater is (171.76 - 51.02) / 0.42977 = 281 W/m².
Engineering question
Represent the very thin heater film as a surface heat source, apply indoor and outdoor convection, and solve the 3D steady-state temperature distribution in the glass.

Simulation problem
Problem Type
A 3D problem of Heat Transfer.
There are 10 mm paddings between the glass edges and the heater.
Heater power 600 W/m².
Indoor air temperature is +20°C, convection coefficient is 8 W/m²*K.
Outdoor air temperature is -15°C, convection coefficient is 23 W/m²*K.
Calculate temperature distribution in the glass.
Film thickness (~0.01 mm) is much less than the glass thickness. So we do not model film as a body, but as a surface with a surface power heat specified instead. For simplicity we assume that the heating power is evenly distributed in the serpentine stripe.
Glass inner surface average temperature is +5.3°C, outdoor surface average temperature is +2.4°C.
