Superheated Steam | Spirax Sarco

The steam is therefore not only dry but also has some degree of superheat. The excess energy = 2 741.7 - 2 706.7 = 35 kJ/kg and this is used to raise the temperature of the steam from the saturation temperature of 120 °C to 136 °C.

$ Delta T = dfrac{0.1 J}{1 mg cdot 1 J/(g K)} = 100°C $ ignoring losses to the environment. So you can't say which voltage or power is needed to heat the resistor to 200°C. The small resistor reaches a very high temperature soon without applying much energy. You'll have to define what thermal energy you need and then we can talk again.
