> peltiers) are essential Peltiers have a lifetime measured in cycles, cycling from active (maximum delta Temp) to inactive (both sides ambient). After 1-2k cycles, Peltiers gradually lose efficiency and transition from a heat pump to a hot plate. For this reason I've avoided them in my own permanent installations. Have you encountered this?
