If the reaction was exothermic, it would increase the entropy of its surroundings as well (or leave the surroundings alone and increase internal temperature and entropy even more), and it would therefore be spontaneous at all temperatures. It is precicely because it is endothermic, and thus lowers the entropy of the suroundings, that the reaction becomes spontaneous only above a certain temperature. | |

Don't call me when the building burns down or something :P But it certainly isn't as convenient as evaporating a liquid. | |

I somehow doubt dumping a flammable liquid into your thermostat, inserting a wick, and lighting it on fire is a satisfactory solution for you. That would be a great solution, although the OP wanted safe.
