We have tried a Peltier Device but it was unable to affect the bimetallic thermostat that we have to close the circuit.
You don't want to heat it up; an endothermic action absorbs energy and cools down. You also aren't limited to a bimetallic strip; there are other reliable options. You can also buy a bimetallic strip by itself - they are usually sold as science demonstration tools.
