Hello, I am an electronic circuit designer needing thermal assistance with a heating element. I have designed of the electronic control circuitry, but the thermal end is out of my expertise. My goal is to first calculate the power required, second - source manufacturing for the element. The project is a coffee mug (think mobile travelers mug). The requirements are to maintain beverage at 175F. Not heat the beverage from ambient, the beverage will all ready be 175 when poured into the cup. I need real math to calculate how much power (wattage) is necessary to maintain this temperature. Again, not heat, need the lowest power maintain. Final element will be running off of 3.7VDC I am looking for math not assumptions, or guess. If you have any manufacturing contacts / suggestion this would also be helpful. Thank you
