The PTC heater pills can be widely applied to electric appliance,like facial sauna,cooking devices,coffee maker,steam iron,etc. If you can characterize the resistance vs temperature of the heating element, your controller could have a separate mode where it initially limits power on startup until you reach some temperature where you know that the resistance is such that the controller turning full on or 100% duty cycle on your PWM will not draw more power than is acceptable to you. A resistor (including a purpose-built electric heating element) always turns 100% of the dissipated energy into heat*, *Of course, any hot object will subsequently radiate away some of its heat as. With this property, they are used as overcurrent protection devices. The resistance of the PTC then increases substantially, which in turn reduces the high current to levels that do not overstress the system. Their compact size, efficient heat transfer, reliability, and ability to self-control the amount of heat produced are highly valued.
