ac/dc module & heat transfer module

Hi,
I have designed a double spiral micro heater using ac/dc & heat transfer module.I have used aluminium material & this is giving heat of 1300k at 0.2v supply voltage(DC).But i am unable to determine the power consumption of the heater so that am not able to choose the write material for the model.So would you be kind enough to tell me the procedure to calculate the power consumption of the heater.



Thanks
